
To compare the population pharmacokinetics (PPK) of IBI305 and bevacizumab in subjects with
advanced or recurrent non-squamous NSCLC

To compare the PD of IBI305 and bevacizumab in subjects with advanced or recurrent non-squamous
NSCLC
Study design:
This is a randomized, double-blinded, multi-center phase III study. The study planned to enroll and randomize 436
subjects with non-squamous NSCLC in a 1:1 ratio to IBI305 plus paclitaxel/carboplatin group or bevacizumab plus
paclitaxel/carboplatin group. Stratifying factors include age (< 60 vs. ≥60 years old) and EGFR status (wild type vs.
unknown type).
Each treatment cycle is 3 weeks for both groups. 15 mg/kg IBI305 or bevacizumab is administered on D1 of each
cycle along with paclitaxel/carboplatin. Subjects will receive up to 6 treatment cycles of combination therapy until
PD, unacceptable toxicity, withdrawal of informed consent, loss to follow-up, or death (whichever comes first).
Then subjects receive maintenance monotherapy, that is, discontinuing paclitaxel/carboplatin while continuing
therapy with IBI305 or bevacizumab. The maintenance monotherapy continues every 3 weeks. On D1 of each
treatment cycle, subjects will be administered 7.5 mg/kg of either IBI305 or bevacizumab until PD, unacceptable
toxicity, withdrawal of informed consent, loss to follow-up, death, or end of study (whichever comes first).
During the study, a CT or an MRI will be performed every 6 weeks (± 7 days) and be determined whether the study
treatment will be continued by investigators at each site through tumor assessments until PD, withdrawal of
informed consent, lost to follow-up, death, start of other anti-tumor therapies, or end of study. If subjects discontinue
the study treatment for reasons other than PD, tumor assessments will be continued until PD, withdrawal of
informed consent, loss of follow-up, death, start of other anti-tumor therapies, or end of study. If subjects discontinue
the study treatment for PD, the investigators will make telephone follow-up every 12 weeks (± 7 days) to collect
information of subsequent anti-tumor therapies and survival until withdrawal of informed consent, lost to follow-up,
death, or end of study.

Statistical methods:
Sample size calculation:
A number of 218 subjects for each group (436 subjects in total) can provide 80% test power to confirm the clinical
equivalence between the treatments of IBI305 in combination with paclitaxel/carboplatin and bevacizumab in
combination with paclitaxel/carboplatin. Estimation parameters for sample size: The significance level of the two-
sided test is 0.05, the ORR of subjects in the IBI305 and bevacizumab groups is about 50.0%, and the equivalence
margin for the ratio of ORR is taken as (0.75, 1/0.75). Based on the above hypothesis, each group requires 218
subjects (436 subjects in total).
Efficacy analysis:
Clinical equivalence will be determined by whether the 90% confidence interval (CI) of the ratio of ORR between
the IBI305 and bevacizumab arms falls within the preset margin of (0.75, 1/0.75). The ORR and 95% CI of two
groups, ORR difference and 90% CI, and ORR ratio and 90% CI will be estimated using the generalized linear
model (GLM, including groups and stratification factors).
Median survival (OS) and survival curves will be estimated using the Kaplan-Meier method. The hazard ratio (HR)
and 95% CI of two groups will be estimated using the Cox model. DORs and PFSs will be analyzed by the same
method as the median survivals. DCR will be analyzed using the same method for primary efficacy endpoints, but
an equivalence test will not be conducted.
Safety analysis:
All adverse events (AE) will be coded using MedDRA and graded according to CTCAE v4.03. All treatment-
emergent adverse events (TEAEs), Grade 3 or greater TEAEs, serious adverse events (SAEs), investigational drug-
related TEAEs, investigational drug-related SAEs, TEAEs leading to treatment discontinuation, TEAEs leading
to study termination, and adverse events of special interest (AESIs) will be listed based on system organ class,
preferred terms, and groups and the numbers of corresponding subjects and percentages will be summarized.
In addition, the severity of TEAEs and the correlation with the study drug will also be summarized by system
organ class, preferred terms, and treatment groups.
Measured values and changes from baseline for vital signs, physical examination, laboratory tests and 12-lead ECG
will be analyzed using descriptive statistics. Baseline results and worst results during the study will be presented in
cross tabulation.
The number and percentage of subjects who developed anti-drug antibodies and neutralizing antibodies during the
study will be summarized by treatment group.
PK/PD exploratory analysis:
Mainly based on description, and inter-group comparison will be carried out if necessary

a.
After completing the on-site end-of-treatment visit 28 days after the last dose, subjects who discontinue the
investigational drug treatment due to reasons other than PD should continue to undergo tumor assessments once
every 6 weeks (±7 days) until PD (and begin post-PD follow-up thereafter), withdrawal of consent, start of another
antineoplastic treatment, loss to follow-up, death, or study completion.
b.
For subjects with PD, collect survival information once every 12 weeks (84 days, ±7 days) by phone until death,
loss to follow-up, withdrawal of informed consent, or study completion. Subsequent antineoplastic treatments
should be documented in the eCRF.
c.
Only measure weight.
d.
Clinical laboratory tests are carried out at the laboratory of each hospital. If screening laboratory tests (routine
blood test, blood chemistry, and urinalysis) are performed within 7 days prior to the first dose, the screening
results may be used as baseline data. For subsequent visits, all laboratory tests have to be completed within 3
days prior to the dose administration.
e.
A urinalysis is required before each IBI305/bevacizumab infusion to test urine protein.
f.
Women of childbearing age should undergo a serum/urine pregnancy test.
g.
Immunogenicity tests will be performed in all subjects at 3 blood sampling time points: Within 1 hour prior to
the first dose of the study treatment (IBI305/bevacizumab) in C1, within 1 hour prior to the administration of
the study treatment in C4, and during the end-of-treatment visit. Blood specimens that are positive for anti-drug
antibodies (ADA) after dosing will be further tested for neutralizing antibodies (NAb). Samples will be tested
at the designated central laboratory.
h.
Image assessments (CT or MRI) of the brain, chest, abdomen, and pelvis should be completed at baseline. If
these tests are performed within 28 days prior to the first dose of the study drug, they do not need to be repeated
unless the investigator believes that there have been changes in the subject's tumor burden. After the start of
treatment, imaging tests are performed once every 6 weeks (±7 days) and have to be completed within 7 days
prior to the scheduled visits, until progressive disease, start of other treatment, withdrawal of informed consent,
loss to follow-up, death, or study completion. The same method of imaging test is used at baseline and during
follow-up. Imaging evaluations of the chest, abdomen, and pelvis are required.
i.
All subjects should undergo tumor tissue EGFR testing.

j.
Each treatment cycle of the investigational product contains 3 weeks. The dose of IBI305 or bevacizumab is 15
mg/kg when used in combination with chemotherapeutic drugs and 7.5 mg/kg in the maintenance monotherapy,
given on D1 of every treatment cycle until progressive disease (PD), unacceptable toxic reactions, withdrawal
of informed consent, loss to follow-up, death, or end of study, whichever occurs first. After all assessments
were completed, the study drug was administered followed by chemotherapy. The first dose of study drug was
completed within 24 h after randomization.
k.
Each treatment cycle is 3 weeks long. Chemotherapy (paclitaxel + carboplatin) is administered on D1 of each
cycle for up to 6 cycles, or until disease progression (PD), unacceptable toxicity, withdrawal of informed
consent, loss to follow-up, or death. Paclitaxel is administered after the infusion of study drug is completed,
followed by carboplatin.

1 INTRODUCTION
1.1 Study Background
1.1.1 Disease background
Lung cancer has the highest incidence and mortality globally among all cancers. According to
the 2012 Global Cancer Statistics (GLOBOCAN 2012) published by International Agency for
Research on Cancer, there were approximately 1.8 million new lung cancer cases worldwide,
which accounted for 13% of the global newly-diagnosed cancers, and 58% of these cases
occurred in underdeveloped areas1. According to the data released by the National Central
Cancer Registry of China in 2015, lung cancer was the most prevalent malignancy in China in
2011, with about 650,000 new cases every year. Lung cancer was also the leading cause of death,
with about 520,000 deaths per year2. The limited clinical treatment of lung cancer is the main
reason for its poor prognosis. There is a huge demand for new types of lung cancer treatment
drugs.
Approximately 85–90% of lung cancers are non-small cell lung cancer (NSCLC) and patients
with NSCLC are usually in the advanced stages when diagnosed3. According to the Chinese
guidelines for the diagnosis and treatment of primary lung cancer, anatomic pulmonary resection
is the mainstay of treatment for early stage lung cancers4. However, despite surgery, some
patients develop distance metastases that eventually lead to death5. Surgery is not possible for
most patients with clearly diagnosed stage IIIB and IV as well as some patients with stage IIIA
NSCLC4. Comprehensive treatment based on systemic therapy is used to maximize patient
survival, control progressive disease, and improve the quality of life6.
In recent years, anti-tumor therapies have entered a new era with the emergency of targeted
drugs. Some of these targeted drugs have demonstrated satisfactory efficacy in the treatment of
advanced NSCLC. These targeted drugs include monoclonal antibodies and tyrosine kinase
inhibitors (TKIs), mostly targeting epidermal growth factor receptors (EGFRs) and vascular
endothelial growth factor (VEGF), such as bevacizumab, cetuximab, gefitinib, erlotinib, and
icotinib. Monoclonal antibodies have become the drugs of choice in various treatment guidelines
due to the good targeting ability, low drug resistance, and good patient tolerability. Bevacizumab
combination chemotherapy is a first-line therapy of NSCLC recommended by the National
Comprehensive Cancer Network (NCCN)7. Additionally, bevacizumab in combination with
paclitaxel/carboplatin has also been approved as the first-line therapy of unresectable advanced,
metastatic, or relapsed non-squamous NSCLC by China Food and Drug Administration (CFDA)
on Jul. 9, 20156.

Compared with traditional chemotherapy that directly inhibit or kill tumor cells, anti-angiogenic
drugs have the following unique advantages8:

The targets are genetically stable vascular endothelial cells (VECs) rather than highly
heterogeneous tumor cells, thus leading to lower drug resistance;

The number of tumor-induced VECs is far less than that of tumor cells, and the efficacy
is preferable targeting on VECs and their cytokines;

Normal VECs are quiescent, whereas tumor VECs are active in proliferation. Anti-
angiogenic therapy targets activated cells and avoids damage to normal VECs, thus
leading to better targeting ability;

Anti-angiogenic therapy can normalize the tumor vessels and thereby reduce the
pressure in tumor tissues. This enhances the delivery of chemotherapeutic agents into
tumor tissues, thus increasing the efficacy of chemotherapy.
Angiogenesis is a basic biological characteristic of tumors. The growth of both solid and
hematologic tumors are depended on angiogenesis regardless of the nature of tumor cells.
Therefore, anti-angiogenic therapy is broad-spectrum and applicable to various tumors.
Bevacizumab is a recombinant humanized monoclonal antibody that selectively binds to human
VEGF and blocks its biological activity. Bevacizumab consists of a framework region of a
human antibody and a humanized murine antigen binding region that can inhibit the binding of
VEGF to its receptors on epithelial cells, Flt-1 and KDR. By blocking the activity of VEGF and
reducing tumor angiogenesis, tumor growth is inhibited9.
In a study conducted by the Estern Cooperative Oncology Group (ECOG), compared with
chemotherapy alone (paclitaxel/ carboplatin), bevacizumab in combination with paclitaxel/carboplatin
significantly increased the overall survival (OS) (median: 12.3 vs. 10.3 months), progression-free
survival (PFS) (median: 6.2 vs. 4.5 months), and overall response rate (ORR) (35% vs. 15%) in
patients with advanced, metastatic, or relapsed non-squamous NSCLC10. In another foreign
AVAiL study, different doses of bevacizumab (7 and 15 mg/kg) in combination with
chemotherapy (cisplatin and gemcitabine) and placebo combine with chemotherapy were
compared for the treatment of non-squamous NSCLC. The study found that the two
bevacizumab groups had significantly increased the PFS (median: 6.7 months (7.5 mg/kg
combination chemotherapy group) vs. 6.5 months (15 mg/kg combination chemotherapy group)
vs. 6.1 months (placebo combination chemotherapy group)) and the ORR (37.8% (7.5 mg/kg
combination chemotherapy group) vs. 34.6% (15 mg/kg combination chemotherapy group) vs.
21.6% (placebo combination chemotherapy group)) in patients with locally advanced, metastatic,
or relapsed non-squamous NSCLC11. In a BEYOND study conducted in China, compared with

placebo in combination with paclitaxel/carboplatin, bevacizumab in combination with
paclitaxel/carboplatin significantly increase the PFS (median: 9.2 vs. 6.5 months), OS (median:
24.3 vs. 17.7 months), and the ORR (54% vs. 26%) in patients with advanced or relapsed non-
squamous NSCLC12.
In China, the antibodies and fusion proteins targeting VEGF are research hotspots. However,
since 2006, the clinical efficacies of various drugs have not been verified and no products have
been marketed. Considering the complexity of macromolecular drugs and the limitations of drug
development capability in China, advanced technologies in antibody development, production,
and quality control is required to develop high-quality VEGF inhibitors that are safe and
effective. IBI305 has showed high similarity to bevacizumab in various pharmaceutical and
nonclinical studies (refer to Investigator's Brochure [IB]). Besides, the efficacy and safety of
bevacizumab for treatment of locally advanced, metastatic or relapsed lung cancer have been
verified. The relevant domestic and external pivotal clinical studies are referable for the protocol
design of IBI305 clinical study. In summary, the clinical study of IBI305 for treatment of
NSCLC has a solid foundation and relatively low risks. The successful development of IBI305
indicates an additional first-line targeted drug for lung cancer in China, providing doctors and
patients with more therapeutic options.
1.1.2 Investigational drug
1.1.2.1 Description of investigational drug
IBI305 is a recombinant humanized anti-VEGF monoclonal antibody injection developed by
Innovent Biologics (Suzhou) Co., Ltd. (hereafter as sponsor) that specifically binds human
VEGF. The molecular weight of IBI305 is 149 KDa. IBI305 specifically binds to VEGF-A,
inhibits the binding of VEGF-A to VEGF-R1 and VEGF-R2, blocks the signaling pathways such
as PI3K/Akt/PKB and Ras-Raf-MEK-ERK. IBI305 also inhibits the growth, proliferation, and
migration of VECs and angiogenesis, decreases the vascular permeability, blocks blood supply to
tumor tissues, inhibits the proliferation and metastasis of tumor cells, and induces the apoptosis
of tumor cells, thereby generates anti-tumor effects. The main active ingredient is recombinant
humanized anti-VEGF monoclonal antibody and excipients include sodium acetate, sorbitol, and
polysorbate 8013. Refer to the Investigator's Brochure for the detailed structure and
physicochemical properties of IBI305.

1.1.2.2 Preclinical studies
Pharmaceutical studies
The pharmaceutical studies showed that stability, primary structure, higher-order structure,
oligosaccharide distribution, charge variant, and product-related impurities of IBI305 are highly
similar to those of bevacizumab, and the process-related impurities meet the proposed
specification. Therefore, IBI305 is considered to have highly similar protein properties and
product quality to bevacizumab13.
Pharmacodynamic studies
In vitro and in vivo pharmacodynamic (PD) studies of IBI305 showed the following findings:
1)
Target: IBI305 displayed specifically high-affinity binding to recombinant human
VEGF-A with an affinity constant same as that of bevacizumab, indicating that IBI305,
the same as bevacizumab, is a specific human VEGF blocker with a clear target.
2)
Specificity: IBI305 displayed specifically high-affinity binding to recombinant human
VEGF-A, medium-affinity binding to canine VEGF-A, but low-affinity binding to
human VEGF-B, VEGF-C, VEGF-D, PlGF, suggesting that IBI305 recognizes specific
targets and has low off-target toxicity risk; no obvious affinity to mouse VEGF-A164
and rat VEGF-A164, suggesting that IBI305 has high species specificity.
3)
Mechanism of action: IBI305 specifically binds to VEGF-A and inhibits the activation
of VEGFR-2 and ERK1/2, blocks the proliferation and migration of HUVEC, and
inhibits the sprouting from rat aortic ring, suggesting that IBI305 antagonizes VEGF-
A-induced signaling pathway to block the proliferation and migration of VECs and
inhibit angiogenesis, which leads to the reduction of nutritional supply and metastasis
of tumor.
4)
Anti-tumor effects: IBI305 significantly inhibits the growth of human colon cancer
Ls174t and lung cancer NCI-H460 cells in xenografts in nude mice, indicating that
IBI305 has significant anti-tumor effects.
Results from in vitro and in vivo studies of IBI305 showed highly similarity with that of
bevacizumab designed simultaneously, demonstrating that the target, mechanism of action,
and anti-tumor effects of IBI305 are highly similar to bevacizumab13.

Pharmacokinetic studies
In vitro and in vivo pharmacokinetic (PK) studies of IBI305 showed the following findings:
1)
IBI305 showed no significant cross-reactivity with normal human tissues and
cynomolgus monkey tissues, and only cross-reacted with the positive-control. i.e.
human angiosarcoma tissue, suggesting that IBI305 is highly specific to cancer tissues
rather than normal human tissues and has very low on-target toxicity.
2)
Linearity: With single dose or repeated doses of IBI305 (2-50 mg/kg) vis intravenous
injection in cynomolgus monkeys, the test showed significant PK, thus reducing the
suddenly rising toxicity risks with increased clinical doses.
3)
Immunogenicity: With single dose or repeated doses of IBI305 or bevacizumab via
intravenous injection in cynomolgus monkeys, the test showed abnormal changes of
drug concentration-time curves in several animals. The anti-drug antibody (ADA) test
results showed that IBI305 has a medium immunogenicity.
4)
Accumulation: With repeated doses of IBI305 or bevacizumab via intravenous
injection in cynomolgus monkeys, the test showed that drug exposure of the last
dose was significantly higher than that of the first dose, and the steady-state drug
concentration after repeated doses was higher than that after a single dose, suggesting
that the drug may be accumulated in body.
The results of tissue cross-reactivity and PK/toxicokinetic studies in cynomolgus monkeys
indicated that IBI305 and bevacizumab have similar characteristics in tissue cross-reactivity and
PK/toxicokinetics13.
Toxicological studies
Toxicological studies of IBI305 showed the following findings:
1)
Single dose: With single dose of IBI305 (up to 300 mg/kg) via intravenous injection in
cynomolgus monkeys, the test showed good tolerability without any abnormal clinical
symptoms and toxicity. The dose was about 48 times the proposed clinical dose for
human based on body surface area. In the safety pharmacology test, with single dose of
IBI305 (50 mg/kg) via intravenous injection in cynomolgus monkeys, the test showed
no significant effects on the central nervous system, respiratory system, and
cardiovascular system, suggesting that the single dose of IBI305 via intravenous
injection has a high safety.

2)
Repeated doses: With repeated doses of IBI305 (up to 50 mg/kg) via intravenous
injection twice weekly for 9 consecutive doses in cynomolgus monkeys, equivalent to
20 times the proposed clinical dose for humans (based on the weight), the test showed
extremely mild to mild linear growth arrest of metaphyseal lines at knee joint and
disordered chondrocyte proliferation, extremely mild increases in macrophage count
in white pulp of spleen, pulmonary (including bronchial) hemorrhage, and deposits of
hemosiderin in lymphoid tissue of bronchial mucosa, indicating that the target organ
toxicities are mainly in the bone, spleen, and lungs.
3)
Immunotoxicity and immunogenicity: With repeated doses of IBI305 via intravenous
injection twice weekly for 9 consecutive doses in cynomolgus monkeys, the test
showed medium immunotoxicity to the spleen. Different doses of IBI305 may result in
the production of ADAs, a portion of which are neutralizing antibodies (NAbs),
indicating that IBI305 has medium immunotoxicity and immunogenicity.
4)
Local irritation test: With repeated dose of IBI305 via intravenous injection in
cynomolgus monkeys, the test showed no irritation at the injection site, suggesting that
administration of IBI305 via intravenous injection is safe and feasible.
5)
In vitro hemolysis assay: With maximum proposed clinical concentration of IBI305
(9 mg/mL), the assay showed no hemolysis, suggesting that IBI305 is suitable for
intravenous injection.
IBI305 has high similarity with bevacizumab in safety pharmacology, long-term toxicity,
immunotoxicity, immunogenicity, local irritation, and hemolysis13.
1.2 Study Principles and Risk/Benefit Assessment
1.2.1 Study principles and dose selection
A biosimilar drug refers to a therapeutic biological product that is similar in quality, safety and
efficacy with an approved reference drug14. IBI305, developed and sold in the market by the
sponsor, is a bevacizumab biosimilar, and has the same administration method and indications
as bevacizumab.

This study is conducted in accordance with the "Guidelines on Development and Evaluation of
Bosimilars (for Trial Version)" issued by the NMPA (formerly CFDA)14. The doses of IBI305
selected in this study are based on the preclinical studies that showed highly similarity between
IBI305 and bevacizumab in pharmacology, PD, PK and toxicology (refer to the Investigator's
Brochure for details). Besides, the efficacy and safety of bevacizumab for treatment of advanced,
metastatic or relapsed non-squamous NSCLC have been verified, and the indications have also
been approved in China. Therefore, the dose and administration of IBI305 is similar to
bevacizumab in this study, that is, 15 mg/kg intravenously on D1 of every 3-week cycle
when used in combination with chemotherapy (paclitaxel and carboplatin). In the subsequent
maintenance monotherapy therapy, IBI305 will be given intravenously at a dose of 7.5 mg/kg on
the first day of every 3-week cycle. This design of this study is to further demonstrate that
IBI305 is similar to bevacizumab in clinical efficacy, safety, and immunogenicity in subjects
with advanced, metastatic or relapsed non-squamous NSCLC.
1.2.2 Risk/benefit assessment
IBI305 is a bevacizumab biosimilar developed by the sponsor. Based on the clinical pharmacology
and toxicology characteristics of IBI305, the risks and benefits of IBI305 are expected to be similar
to bevacizumab.
The treatment-related risks of bevacizumab are detailed in its prescribing information. This study
is the first human study of IBI305 so that unexpected adverse reactions will be possible. The
design of this study ensures the minimized subject risks by close monitoring of the adverse
events (AEs) before, during, and after the infusion of the investigational drugs. Once an adverse
reaction occurs, the investigator will immediately take appropriate action for the subject safety.
The platinum-based therapy is the standard first-line regimen of advanced NSCLC4. This study
uses the combination of paclitaxel/carboplatin, ensuring the basic anti-tumor therapy for subjects.

3 STUDY PLAN
3.1 Overview of Study Design
This is a randomized, double-blind, active-controlled, and multi-center phase III study. A total of
436 subjects across 35 study sites with non-squamous NSCLC will be planned, randomized in a
1:1 ratio into the IBI305 plus paclitaxel/carboplatin group or bevacizumab plus paclitaxel/carboplatin
group, and stratified according to age (< 60 vs. ≥60 years old) and epidermal growth factor
receptor (EGFR) status (wild type vs. unknown type). Each treatment cycle is 3 weeks for both
groups. 15 mg/kg IBI305 or bevacizumab is administered on D1 of each cycle along with
paclitaxel/carboplatin. Subjects will receive up to 6 treatment cycles of combination therapy until
PD, unacceptable toxicity, withdrawal of informed consent, loss of follow-up, or death
(whichever comes first). Then subjects received maintenance monotherapy, that is, discontinuing
paclitaxel/carboplatin while continuing maintenance therapy with IBI305 or bevacizumab. The
maintenance monotherapy continues every 3 weeks. On D1 of each treatment cycle, subjects will
be administered 7.5 mg/kg of either IBI305 or bevacizumab until PD, unacceptable toxicity,
withdrawal of informed consent, lost to follow-up, death, or end of study (whichever comes first).
After discontinuing the study drug, subjects will return to the study site 28 days (± 7 days) after
the last dose for an end-of-treatment visit. If the subjects discontinue the study treatment for
reasons other than PD, subsequent follow-up will be continued until PD, withdrawal of informed
consent, start of other anti-tumor therapies, loss of follow-up, death, or end of study. If the
subjects discontinue the study treatment for PD, the investigator will make telephone follow-up
every 12 weeks (± 7 days) to collect information of subsequent anti-tumor therapies and survival.
A CT or an MRI will be performed every 6 weeks (± 7 days) until PD, withdrawal of informed
consent, start of other anti-tumor therapies, loss of follow-up, death, or end of study. The method
for subsequent imaging examination should be consistent with that at baseline, and the chest,
abdomen and pelvis of the subject must be scanned. Each assessment must be completed within
7 days from the most recent visit. The investigators then perform the evaluation based on the
RECIST v1.1 criteria to determine whether the subject can continue receiving the next cycle of
treatment. Furthermore, the independent tumor evaluation committee (Section 11.1.1) will also
evaluate tumor response according to the RECIST v1.1. If the subjects discontinue the study
treatment for reasons other than PD, subsequent tumor evaluation should be continued according
to the study procedures until PD, withdrawal of informed consent, start of other anti-tumor
therapies, loss of follow-up, death or, end of study.
The study design is shown in Figure 1.

* If the subject is determined by the investigator and the sponsor's doctor to be medically suitable
to continue with the study drugs without any risk or inconvenience, the mistakenly enrolled or
randomized subject will continue with the study treatment and assessments.
In any cases, reasons for withdrawal must be documented in the eCRFs. If the subject withdraws
from the study prematurely for any reason, the investigator should make every effort to persuade
the subject to receive the corresponding assessment, and continue the follow-up of all unresolved
AEs based on the AE reports and follow-up requirements (Table 2):

If the subject withdraws during the study, the series of assessments listed under the End
of Treatment Visit (Section 6.9) should be performed

If the subject withdraws after the end of the treatment visit and has not experienced PD,
the series of assessments listed under the Follow-Up for PD (Section 6.10) should be
performed (tumor assessment is not required to be repeated if it has been performed
within 6 weeks prior to this follow-up)

If the subject withdraws during the follow-up for survival, the information of subsequent
anti-tumor therapies and survival should be collected by telephone follow-up only

5 STUDY TREATMENT
5.1 Therapies by Study Drugs
The study drugs of this study are IBI305 and bevacizumab.
In this study, the dose of IBI305 or bevacizumab during combination therapy with chemotherapy
is 15 mg/kg, while the dose during maintenance monotherapy is 7.5 mg/kg. The study drugs are
administered intravenously on D1 of each 3-week cycle until PD, unacceptable toxicity,
withdrawal of informed consent, loss to follow-up, death, or end of study (whichever comes first).
The duration of the first dose of IBI305 or bevacizumab should be 90 min (± 15 min). If the
first infusion is well-tolerated by the subject, then the duration of the second infusion can be
shortened to 60 min (± 15 min). If the 60 min infusion is also well-tolerated by the subject, then
the subsequent infusions can be completed within 30 min (± 15 min).
5.2 Chemotherapy
Paclitaxel will be administered after the IBI305 or bevacizumab infusion is completed, then
followed by carboplatin:
Paclitaxel: 175 mg/m² administered via intravenous infusion for 3 h (may be adjusted according
to clinical practice of each study site) on D1 of every 3-week cycle for up to 6 cycles until PD,
unacceptable toxicity, withdrawal of informed consent, loss of follow-up, or death.
Carboplatin: AUC 6.0, the infusion time is based on the standard practice of each study site,
administered on D1 of every 3-week cycle for up to 6 cycles until PD, unacceptable toxicity,
withdrawal of informed consent, loss of follow-up, or death.
The chemotherapeutic agents are supplied by the sponsor.
Formulas for calculating surface area, creatinine clearance and carboplatin dose are shown in
Section 13.2.
5.3 Dose Adjustment of Each Study Drug
5.3.1 General principles
The reasons for dose adjustments or delayed administration, measures taken, and
results should be documented in the medical records and eCRFs

Confidential
If the concomitant symptoms exist at baseline, the investigator will determine whether
the dose should be adjusted according to the change in severity of toxicity. For example,
if the subject has Grade 1 "weakness" at baseline and Grade 2 "weakness" during the
study treatment, the dose should be adjusted based on Grade 1 toxicity since the
severity has increased by one grade
If several toxic reactions of different grades or severity occur simultaneously, the dose
will be adjusted according to the highest observed grade/severity
If a dose adjustment is required solely due to abnormal lab test results, then the dose
should be adjusted based on the measured values obtained prior to the start of the
treatment cycle
If the investigator determines that the toxicity is unlikely to further develop into a
serious or life-threatening event, the current dose will be continued without any
adjustments or treatment interruptions. In addition, dose adjustments or treatment
interruptions will not be performed for non-hemolytic anemia as the symptoms can be
alleviated through blood transfusions.
If the investigator determines that a toxicity is caused by a specific therapeutic drug,
then the dose adjustments of other drugs are not required
Discontinuation of one or two therapeutic drugs before PD will not affect the continued
treatment with other drugs
Dose reductions or adjustments of IBI305 or bevacizumab are not permitted.
Subsequent therapeutic dose will not be adjusted according to weight change, unless
the subject weight has changed by ≥10% from baseline
Once the dose of any chemotherapeutic agents is reduced, the original dose should no
longer be adopted
If any but not all of the therapeutic drug (IBI305, bevacizumab or chemotherapeutic
agents) treatments is interrupted due to toxicity, then this treatment will be considered
as a treatment cycle
If the administration of any one of the chemotherapeutic agents is delayed for more
than 3 weeks, the subject should permanently discontinue that chemotherapeutic agent

5.3.2 Dose adjustments of study drugs
Dose adjustments of IBI305 or bevacizumab are not permitted except for the adjustments
(adjusted to 7.5 mg/kg for maintenance monotherapy) specified in the study protocol. The dose
of IBI305 or bevacizumab is calculated according to the subject weight at baseline (prior to the
first dose), and remains unchanged throughout the study, unless the subject weight has changed
by ≥10% from baseline.
If an infusion reaction occurs during a 60-minute infusion, the infusion time should be extended
to 90 minutes for all subsequent infusions. Likewise, if an infusion reaction occurs during a 30-
minute infusion, the infusion time should be extended to 60 minutes for all subsequent infusions.
IBI305 or bevacizumab in combination with paclitaxel/carboplatin will be administered every
3-week treatment cycle for 6 cycles. If PD is not observed in subject during treatment, then the
subject will continue to receive IBI305 or bevacizumab as maintenance monotherapy every 3-
week treatment cycle until PD, unacceptable toxicity, withdrawal of informed consent, loss of
follow-up, death, or end of study (whichever comes first).
If IBI305 or bevacizumab is permanently discontinued due to unacceptable toxicity or subject
refusal to continue the study drugs during the combination therapy, then the subject will continue
to receive the chemotherapy (paclitaxel/carboplatin) until 6 treatment cycles are completed as
determined by the investigator. If any one of the chemotherapeutic agents (paclitaxel or carboplatin)
is prematurely discontinued due to unacceptable toxicity, the subject can continue to receive
IBI305 or bevacizumab treatment until PD, unacceptable toxicity, withdrawal of informed
consent, loss of follow-up, or death (whichever comes first).
When a Grade 3 or 4 IBI305- or bevacizumab-related toxicity is observed, the investigators
should determine whether to continue or terminate IBI305 or bevacizumab treatment according
to the followings:
First occurrence:
IBI305 or bevacizumab administration should be interrupted until toxicity symptoms return to
baseline level or are at least reduced to the Common Terminology Criteria for Adverse Events
(CTCAE) Grade 1 or lower (except for the special circumstances listed below)
Note that when Grade 4 febrile neutropenia and/or thrombocytopenia occur(s), IBI305
or bevacizumab administration should be interrupted until the symptoms return to
baseline levels or at least reduced to CTCAE Grade 1 or lower, since these events
increase the risk of hemorrhage.

Re-occurrence in re-administration:
If Grade 3 IBI305- or bevacizumab-related toxicity occurs again, the investigator
should assess the risk/benefit of study drug continuation for the subject. If such toxicity
re-occurs again after re-administration, IBI305 or bevacizumab should be permanently
discontinued
If Grade 4 IBI305- or bevacizumab-related toxicity occurs again, IBI305 or
bevacizumab should be permanently discontinued
Measures should be taken in the following special circumstances (classified based on CTCAE
version 4.03):
Hemorrhage
Subjects with Grade 3 or 4 hemorrhages should be treated accordingly and permanently
discontinue the study treatment
Thrombosis/embolism

Subjects with arterial thrombosis of any severity grades should permanently
discontinue the study treatment

Subjects with Grade 4 venous thrombosis should permanently discontinue the
study treatment

Subjects with Grade 3 venous thrombosis should interrupt the study treatment. If
the anticoagulant therapy at the planned therapeutic dose is < 2 weeks, the study
treatment should be interrupted until the anticoagulant therapy is completed. If
the anticoagulant therapy at the planned therapeutic dose is > 2 weeks, IBI305
or bevacizumab administration should be interrupted for 2 weeks, and the study
treatment can be restarted during the anticoagulant therapy if the following criteria
are met:
- INR is within the target range (usually 2-3) prior to restarting of study treatment
- Subjects must not have experienced Grade 3 or 4 hemorrhage since enrollment
- No signs of great vessel invasion or adjacency to great vessels from previous
tumor assessments
Note: Therapeutic dose of anticoagulant therapy is defined as the escalating dose of
warfarin or other anticogulants until INR is maintained at no less than 1.5 (usually

Posterior reversible encephalopathy syndrome (PRES)
There have been a few reports of subjects with signs and symptoms consistent with PRES after
study treatment. This is a rare neurological disease and its signs and symptoms include epilepsy,
headache, altered mental status, visual impairment, or cortical blindness, with or without
hypertension. Subjects with PRES should permanently discontinue the study treatment.
Proteinuria
Urinalysis should be performed prior to each dose of IBI305/bevacizumab unless a 24-hour
urinary protein test has already been done.
First occurrence of proteinuria:
After carrying out the urinalysis, if:
Urine protein is < 2+, continue study treatment as scheduled, no additional tests are
required.
≥2+ (urinalysis): perform 24-hour urinary protein test within 3 days prior to
administration:
•
24-hour urinary protein ≤2 g: continue study treatment as scheduled. and perform
urinalysis dipstick test before each scheduled dose.
•
24-hour urinary protein > 2 g: delay study treatment until 24-hour urinary protein ≤2 g.
and a 24-h urine protein test prior to each subsequent dose is performed until urine protein is
reduced to ≤1 g/24 h. Interrupt study treatment only when 24 h urine protein is > 2 g.
Second and subsequent occurrence of proteinuria:
< 3+ (urinalysis): continue study treatment as scheduled, no additional tests indicated.
≥3+ (urinalysis): perform 24-hour urinary protein test within 3 days prior to
administration:
• 24-hour urinary protein ≤2 g: continue study treatment as scheduled.
• 24-hour urinary protein > 2 g: delay study treatment until 24-hour urinary protein ≤2 g.
and a 24-h urine protein test prior to each subsequent dose is performed until urine protein is
reduced to ≤1 g/24 h. Interrupt study treatment only when 24 h urine protein is > 2 g.
Nephrotic syndrome (Grade 4): Study treatment is permanently discontinued

If gastrointestinal perforation occurs, appropriate measures should be taken and the study
treatment should be permanently discontinued.
Wound healing complications
The study treatment should not begin within 28 d after a major surgery, or before the surgical
wound is fully healed. If a complication of wound healing occurs during study treatment, the
study treatment should be interrupted until the wound is fully healed. If an elective surgery is
required, the study treatment should be interrupted.
Abdominal abscess or fistula
If abdominal abscess or fistula occurs, the study treatment should be discontinued. However, the
investigator will determine whether study treatment will be continued if the above AE is resolved.
Infusion-related and allergic reactions:
Infusion-related reactions after first dose of the study drug is uncommon (< 3%), and the incidence
of a severe reaction is only 0.2%.
If a mild (grade 1 or 2) reaction (such as fever, chills, headache, and nausea) occurs, pretreatment
prior to subsequent administration should be performed and infusion time should not be reduced.
If the subject is well-tolerated during infusion after pretreatment, the infusion time can be
reduced by 30 minutes (+10 minutes) for subsequent administration with pretreatment. If an
infusion-related AE occurs during a 60-minute infusion, the subsequent infusion should be
completed within 90 minutes (+15 minutes) with pretreatment. Likewise, if an infusion-related
AE occurs during a 30-minute infusion, the subsequent infusion should be completed in 60 minutes
(+10 minutes) with pretreatment. If a subject has a grade 3 infusion-related reaction, the study
treatment should be interrupted and not be restarted on the same day. However, since there lacks
the dose adjustment method for grade 3 infusion-related reactions, the investigators may decide
to either discontinue the study drug or perform pretreatment, and complete the infusion within
90 minutes (+15 minutes). If an adverse reaction still occurs during a 90-minute infusion, the
infusion should be continued at a slower rate and then gradually returned to a 90-minute infusion.
If the investigator is uncertain about the handling, the study treatment should be discontinued.
When the study treatment is restarted, the subject should be closely monitored based on routine
clinical practice until the possible time of adverse reaction has passed. If a subject has a grade 4
infusion-related reaction, the study treatment should be discontinued.
An allergic reaction is defined as the vascular collapse or shock (systolic BP < 90 mmHg,
unresponsive to rehydration) that occurs within 30 minutes of a study drug infusion caused by
an allergy, with or without respiratory distress. Skin reactions include pruritus, urticaria, and
angioedema. Subjects with allergic reactions should discontinue the study treatment.

5.3.3 Dose adjustments of chemotherapy
Paclitaxel and carboplatin should be administered according to the study site guidelines and local
prescribing information. For the specific information for use, preparation, and storage of
paclitaxel and carboplatin, refer to the prescribing information and local dosing information.
Carboplatin-based chemotherapies have a relatively high incidence of emesis. Therefore,
antiemetics for prophylaxis can be used.
Hematological toxicity:
Absolute neutrophil count (ANC; dose can only be reduced when febrile neutropenia occurs.
ANC must be ≥1.5 × 109/L and platelet count must be ≥100 × 109/L on D1 of each treatment
cycle). Once the chemotherapeutic dose is reduced due to febrile neutropenia or
thrombocytopenia (platelet count < 25 × 109/L or 50 × 109/L with hemorrhage or blood
transfusion required), the original dose should no longer be adopted. If the dose reduction is
required for the third time, the chemotherapy should be immediately discontinued.

Chemotherapy may be delayed for up to 3 weeks. If after the chemotherapy has been delayed for
3 weeks, ANC does not reach ≥1.5 × 109/L and platelet count does not reach ≥100 × 109/L on
D1 of the scheduled chemotherapy, the chemotherapy should be permanently discontinued. If the
above values have been reached, the next course of chemotherapy should be continued.
The investigator should monitor the subject closely for toxicity with particular attention to early
and evident signs of myelosuppression, infection, or febrile neutropenia to timely and
appropriately treat the complications.
Subjects should be informed to pay attention to these signs and receive treatment as soon as possible.
If the chemotherapy must be interrupted due to hematological toxicity, the complete blood count
should be performed regularly (including WBC differentials) until all the counts reach the minimum
requirements for treatment continuation. Thereafter the scheduled treatment plan will be performed.
Dose adjustments are not required for anemia. However, treatment based on guidelines of each
clinic should be performed.
Gastrointestinal toxicity
Antiemetics will be used to control nausea and/or emesis. If grade 3 or 4 nausea and/or emesis
occur(s) despite of antiemetics, the chemotherapeutic dose should be reduced by 20% for the
next treatment cycle. The dose should be returned to the initial level as possible if the subject is
tolerated.
If the subject experiences stomatitis on D1 of any treatment cycle, the chemotherapy should be
interrupted until the symptoms resolve. If the stomatitis has not resolved after 3 weeks, the
chemotherapy should be permanently discontinued (refer to CTCAE version 4.03). If an acute
Grade 3 stomatitis occurs, the chemotherapeutic dose should be reduced to 75% of the proposed
dose when symptoms resolve.
Hepatotoxicity (Paclitaxel)
The paclitaxel dose should be determined based on the lab values measured on D1 of each
treatment cycle.

If paclitaxel is interrupted due to hepatotoxicity, carboplatin should also be interrupted until
paclitaxel is restarted. Paclitaxel will be interrupted for up to 3 weeks. If the subject's hepatic
function does not return to the acceptable ranges in 3 weeks, paclitaxel should be permanently
discontinued. The carboplatin dose will not be adjusted when hepatotoxicity occurs.
The investigators should avoid PD due to abnormal hepatic enzyme levels as possible. If PD
occurs, all the study drugs should be permanently discontinued, including chemotherapy.
Cardiovascular toxicity (paclitaxel)
The arrhythmia in subjects was infrequent in previous clinical studies. However, most subjects
were asymptomatic and electrocardiographic monitoring was not required. Asymptomatic
transient bradycardia was observed in 29% of subjects, but significant atrioventricular block was
rare. Cardiac events should be treated as follows:
Asymptomatic bradycardia: no intervention indicated
Symptomatic arrhythmia during infusion: Discontinue paclitaxel infusion and perform
routine treatment of arrhythmia. Discontinue subsequent paclitaxel treatment.
Document this AE in the AE Report Form of eCRF.
Chest pain and/or symptomatic hypotension (< 90/60 mmHg or rehydration therapy
required): discontinue the paclitaxel infusion. Perform electrocardiography (ECG). If
hypersensitivity reaction is suspected, administer diphenhydramine and dexamethasone
via intravenous infusion. If the chest pain is not considered as cardiogenic, epinephrine
or bronchodilators will be administered. Document this AE in the AE Report Form of
eCRF. Discontinue subsequent paclitaxel treatment and provide symptomatic treatment.
Consult a cardiologist if needed.
Neurotoxicity (paclitaxel)
The dose of paclitaxel should be adjusted according to Table when neuropathy occurs. The dose
adjustment of carboplatin is not needed when neurotoxicity occurs.

Grade 3 or above
Interrupt treatment until return to grade 1, then reduce dose to 125 mg/m2

Once the dose is reduced due to neurotoxicity, the original dose should no longer be adopted.
If the neurotoxicity does not return to grade 1 after paclitaxel interruption for 3 weeks, paclitaxel
should be permanently discontinued.
Allergic reactions/hypersensitivity reactions (paclitaxel)
Note: Prophylaxis for hypersensitivity reactions (see below) and close monitoring of vital signs
are recommended for subjects with history of mild to moderate hypersensitivity reactions when
hypersensitivity reactions reoccur.
Mild symptoms: complete paclitaxel infusion. Close monitoring; no treatment indicated.
Moderate symptoms: Interrupt paclitaxel infusion, administer diphenhydramine 25–
50 mg and dexamethasone 10 mg via intravenous infusion. Once symptoms have
resolved, resume paclitaxel infusion at a slower rate (20 mL/hour for 15 minutes, then
at 40 mL/hour for 15 minutes, and if no further symptoms develop, continue at original
rate until infusion is complete). Document this AE in the AE Report Form of eCRF. If
symptoms reoccur, interrupt the paclitaxel infusion and permanently discontinue
subsequent paclitaxel infusion.
Severe and life-threatening symptoms: Interrupt paclitaxel infusion, administer
diphenhydramine and dexamethasone via intravenous infusion (as above). Use
epinephrine or bronchodilators if indicated. Document this AE in the AE Report Form
of eCRF. Subsequent courses of paclitaxel infusion should be permanently
discontinued.
Moderate or severe hypersensitivity reactions should be documented as AEs.
Other toxicities
If other unmentioned grade 3–4 toxicities occur, the chemotherapy should be interrupted until
symptoms resolve or return to grade 1. Thereafter restart the infusion at 50% of the original dose
(which should no longer be adopted). If the toxicity does not return to grade 1 after an
interruption for 3 weeks, the chemotherapy should be permanently discontinued. Dose
adjustments are not recommended for grade 1 and 2 toxicities.

5.8 Blinding
This is a randomized, double-blind, and active-controlled study, and only relevant study
personnel had access to the randomization numbers. A non-blinded pharmacist or research nurse
will prepare the medications since IBI305 and bevacizumab do not have an identical appearance.
The pharmacist or research nurse who is responsible for preparing the study drugs is not allowed
to disclose any information regarding treatment allocation to the subject, the subject's family
members, or other personnel including the physician and the relevant study staff.
Unblinding: Subject unblinding should only be performed after database locking.
Emergency unblinding: In case of an emergency where the investigator must know the
medication given to a particular subject, the investigator will unblind the subject via the IWRS
and immediately inform the sponsor and CRO. The reasons for unblinding, date, and outcomes
should be documented in the source document and eCRF of the subject.
5.9 Concomitant Medications and Treatments
All medications except for the study drugs, including other chemotherapies not specified in the
study, Chinese herbal medicines, and other non-traditional therapies, are considered concomitant
medications. All concomitant medications used within 30 days prior to screening should be
documented in the eCRFs, including the information of generic name, route of administration,
start date, end date, and indication.
5.9.1 Prohibited treatment
No other anti-tumor therapies or medications with anti-tumor indications, including Chinese
herbal medicine, radiotherapy, or other investigational drugs, are allowed during this study other
than IBI305, bevacizumab, paclitaxel, and carboplatin.
Severe myelosuppression is possible after chemotherapy. Granulocyte colony-stimulating factor
or granulocyte-macrophage colony-stimulating factor are not allowed to be used prophylactically
in the first treatment cycle.
5.9.2 Permitted treatment
Prophylactic use of anti-emetics, glucocorticoids, or other treatments targeting toxicities is permitted
during the study. Unconventional treatments (such as acupuncture) and vitamins/microelements are
permitted if their use does not affect the study endpoints as determined by the investigators.
Starting from the 2nd chemotherapy cycle, granulocyte colony-stimulating factor or granulocyte-
macrophage colony-stimulating factor are allowed to be used prophylactically to prevent severe
myelosuppression.

If the subject has not experienced PD, the subsequent follow-up for PD will be performed
(Section 6.10). If the subject has experienced PD, the subsequent follow-up for survival will be
performed (Section 6.11).
6.10 Disease Progression Visit
If the study drugs are discontinued for reasons other than PD, the end of treatment visit in study
sites will be conducted in 28 days after the last dose of study drug, and tumor assessments should
be conducted every 6 weeks (±7 days) until PD if possible (after which, follow-up for survival
will be conducted [Section 6.11]), withdraw of informed consent, loss to follow-up, death,

measurements will be performed, and any subsequent anti-tumor therapies will be documented.
6.11 Survival Follow-Up
The investigator will make telephone follow-up every 12 weeks (±7 days) to collect the
information of subsequent anti-tumor therapies and survival until withdrawal of informed
consent, loss to follow-up, death, or end of study.
6.12 Study Completion
The end of this study will be the18th month after randomization of the last subject. If the subjects
continue to receive the study drug treatment before this cut-off time, the treatment should be
discontinued and the end of treatment visit should be completed (Section 6.9).

6.13 Tumor Assessment
Imaging tests (CT or MRI) of the brain, chest, abdomen, and pelvis are required at baseline. If
these tests are performed within 28 days prior to the first dose of the study drug, they do not need
to be repeated unless the investigator believes that there have been changes in the subject's tumor
burden. After the start of treatment, imaging tests are performed once every 6 weeks (±7 days)
and have to be completed within 7 days prior to the scheduled visits, until progressive disease,
start of other treatment, withdrawal of informed consent, loss to follow-up, death, or study
completion. The same method of imaging test was used at baseline and during follow-up.
Imaging evaluations of the chest, abdomen, and pelvis are required.
The investigator should perform a tumor assessment based on RECIST v1.1 (Section 13.3) prior
to each dose to determine whether the subject should continue with the next round of treatment.
An independent review committee will also assess the tumor response (Section 11.1.1). Imaging
tests will not be rescheduled if the study drugs or chemotherapeutic agents are interrupted due to
toxicities. Every effort should be made to continue the schedule for imaging tests even for
subjects who discontinue one or two study treatment(s) due to drug-related toxicities.
If subject experience PD according to the RECIST v1.1 criteria, the attending doctor should
discuss with the subject regarding subsequent routine cancer therapies.
6.14 Clinical Laboratory Evaluations
Clinical laboratory tests will be conducted at the laboratories of each study site. Sample collection
and analysis should be performed according to the requirements of each laboratory.
The following laboratory tests should be conducted according to the study procedures (Table 1.

➢
Pregnancy test: Serum/urine pregnancy tests are performed on women of
childbearing age during screening and the end-of-treatment visit.
These tests are carried out at the laboratory of each trial site.
For subsequent visits, all laboratory tests need to be completed within 3 days prior to the
administration. During the study, the frequency of these laboratory tests will be increased if
safety is a concern. The investigator should review the laboratory test results throughout the
study to determine whether the results are clinically significant. The investigator should assess
the changes in laboratory test results. If the investigator considers a laboratory test result to be
abnormal and of clinical significance, it is considered as an AE.
6.15 Vital Signs, Physical Examinations, and Other Safety Assessments
6.15.1 Vital signs
Vital signs include pulse, BP, temperature, and respiratory rate. The subject must rest for at least
5 minutes prior to each vital sign assessment.

7 STUDY ASSESSMENTS
7.1 Efficacy Assessment
7.1.1 Primary efficacy endpoint

Objective response rate (ORR)
ORR will be assessed using RECIST v1.1. ORR is defined as the proportion of subjects with
tumor size reduction of a predefined amount and for a minimum time period, including patients
who achieved complete response (CR) and partial response (PR). The cut-off date for data
included in the primary efficacy evaluation is the 18th week after the last subject is randomized.
7.1.2 Secondary efficacy endpoints

Duration of response (DOR)

Progression-free survival (PFS)

Disease control rate (DCR)

Overall survival (OS)
Each endpoint will be assessed using RECIST v1.1.
DOR is defined as the time from initial tumor response (CR or PR) to PD or death before PD;
Subjects with CR or PR who do not progress or die will be censored on the date of the last tumor
assessment.
PFS is defined as the time from the date of randomization to the date of PD or death; Subjects
who do not progress or die will be censored on the date of the last tumor assessment.
DCR is defined as the proportion of patients whose tumor volume has reduced to a
predetermined value for a minimum time limit, including patients who achieved CR, PR, and SD.
OS is defined as the time from the date of randomization to the date of death of any cause. For
subjects that are alive on the date of study completion or are lost to follow-up, their survival time
will be censored at the date of last contact.

7.2 Safety Assessments
7.2.1 Adverse events
7.2.1.1 Definition
Adverse event
An AE refers to any untoward medical occurrence in a subject after signing the informed consent
form, and does not necessarily have a causal relationship with the treatment. Thus, an AE can be
any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or
disease, whether considered drug related.
Abnormalities resulting from PD are not considered as AEs.
Serious adverse event
A SAE refers to an AE meeting at least one of the followings:
(1)
Lead to death, except for deaths caused by PD.
(2)
Life-threatening (a "life-threatening event" is defined as an AE when the subject is at
immediate risk of death at the time, but does not include the case that may lead to death
only when the event worsens).
(3)
Requires hospitalization or prolonged hospitalization, excluding an emergency or
outpatient visit. Subjects with existing diseases or conditions prior to the enrollment
that do not worsen during the study, and having hospitalization and/or surgery that was
scheduled before the study or during the study do not meet the SAE criterion.
Hospitalizations resulting from PD are not considered as SAEs.
(4)
Results in permanent or severe disability/incapacity.
(5)
Results in congenital anomalies/birth defects.
(6)
Other important medical events: The event that does not result in death, is not life-
threatening or does not require hospitalization, but may jeopardize the health of subjects
and require medical intervention to prevent the SAEs above, is considered as an SAE
7.2.1.2 Severity of adverse events
The severity of AEs is evaluated using the 5-level criteria of NCI CTCAE v4.03.
For AEs not included in CTCAE v4.03, use the following CTCAE general guidelines:

Grade 1: Mild; asymptomatic or mild signs; clinical or diagnostic observations only;
medical intervention not indicated.


Grade 2: Moderate; minimal/local or noninvasive intervention indicated; limiting age-
appropriate instrumental activities of daily life (such as cooking, shopping, using the
phone, financial management, etc.).

Grade 3: Severe or clinically significant but not immediately life-threatening;
hospitalization or prolonged hospitalization indicated; disability; limited ability of self-
care (such as bathing, dressing, undressing, eating, using the toilet, taking medication),
but not bedridden.

Grade 4: Life-threatening consequences; urgent intervention indicated.

Grade 5: Death related to AE
7.2.1.3 Relationship between adverse events and the investigational drug
The relationship between the study drugs and AEs can be determined using the followings:
Table 1. Correlation between AEs and investigational drugs

7.2.1.7 Pregnancy
Bevacizumab may be harmful to the fetus. Subjects or female partners of male subjects must use
an effective form of contraception during the 6 months after the last dose.
During the study, if a female subject exposed to the study drug becomes pregnant, she must
discontinue study treatment. The investigator must report to the sponsor within 24 hours of
noticing the event and submit the "Innovent clinical Study Pregnancy Report/Follow-Up Form".
During the study, if a female partner of a male subject exposed to the study drugs becomes
pregnant, the subject will continue in the study. The investigator must report to the sponsor
within 24 hours of noticing the event and submit the "Innovent Clinical Study Pregnancy
Report/Follow-Up Form".
The investigator must continuously monitor and visit on the outcome of the pregnancy until 8
weeks after the subject gives birth. The outcome should be reported to the sponsor.
If the outcome of the pregnancy is stillbirth, spontaneous abortion, fetal malformation (any
congenital anomaly/birth defect), or medical abortion, it should be considered as an SAE and the
event is required to be reported in accordance with SAE procedures and time limits.
If the subject also experiences a SAE during the pregnancy, the CFDA SAE Report Form should
also be filled out and reported according to SAE's procedures.
7.2.1.8 Time limits of documenting and reporting AEs
All AEs occurring from the time the subject signs the informed consent form to the time
specified in the protocol (Table 2) (including SAEs and non-SAEs), regardless of their severity,
must be collected and recorded on the AE page of the eCRF.
The investigator must fill out all the required information, including the description of the AE,
start date, end date, severity, measures taken, outcome, seriousness, and causality with the
investigational drug. Each AE should be documented separately.

7.2.1.9 Precautions for AE documentation
Diagnosis, signs, and symptoms
If a diagnosis is already made, the eCRF should record the diagnosis instead of individual
symptoms and signs (such as hepatic failure rather than jaundice, transaminase increased, and
asterixis). However, if the signs and symptoms cannot be attributed to a definitive diagnosis, each
independent event should be documented in the eCRFs as an AE or SAE. Update the report with
visit information if a diagnosis is confirmed later.
AEs secondary to other events
Generally, AEs secondary to other events (such as result of another event or clinical sequelae)
should be documented as the primary event, unless the event is severe or an SAE. However,
clinically significant secondary events should be recorded as independent adverse events in the
eCRFs if they occur at different times than the primary event. If the relationship between events is
unclear, document them as separate events in the eCRFs.
Ongoing or recurrent AEs
An ongoing AE refers to an event that does not resolve and is ongoing between two assessment
time points. These AEs should only be documented once in the eCRFs. The initial severity should
be documented, and the information should be updated if the event exacerbates.
Recurring AEs refer to AE that have resolved between the two time points of assessment but
subsequently occur. These events should be independently documented in the eCRFs.
Abnormalities in laboratory tests/vital signs
All clinically significant laboratory test abnormalities should be reported as AEs. It is the
responsibility of the investigator to review all abnormal laboratory test results, and to make
medical judgments as whether each abnormal laboratory test result should be reported as an AE.

Death
During the entire course of the study, all the deaths that occurred within 90 days after the last dose
were documented in the Death Report Form in the eCRFs, regardless of the causality with the
investigational drug.
When recording a death event, if the cause of death is clear, the cause of death is recorded as an
adverse event with the result of the adverse event being death, and the event is reported as an SAE;
if the cause of the death is unknown at the time of reporting , "Death with Unknown Cause" should
be recorded on the Adverse Event Form of the eCRF and the "Death with Unknown Cause" should
be reported as an SAE first before further investigation is carried out to find the exact cause of
death.
Pre-existing medical conditions
Symptoms/signs presenting during the screening period will be recorded and reported as AEs only
if their severity, frequency, or property becomes aggravated (except for worsening of the studied
disease). The relative change should be documented, such as "increased frequency of headaches".
Hospitalization and prolonged hospitalization, or surgery
Any AE that results in hospitalization or prolonged hospitalization should be documented and
reported as an SAE, except for the following situations:

Hospitalization or prolonged hospitalization as required by study protocol (such as for dose
administration, efficacy evaluation, etc.)

Hospitalization due to a pre-existing medical condition that remains stable, e.g. elective
surgery/therapy scheduled prior to the study.
However, elective surgery/therapy required because of the exacerbated condition during the study
(e.g. surgery/therapy required earlier than scheduled) should be considered as an AE.
The investigator should fill in all required information, including AE terms
(diagnostic terms, or the record of symptoms and signs including laboratory test abnormalities if
there is no diagnosis), start date, end date, severity level, whether it is an AESI, measures taken for
the investigational product, treatment given for the AE, outcome, seriousness, and relationship with
the investigational product. If the signs and symptoms cannot be attributed to a definitive diagnosis,
each AE should be documented independently.

Progressive disease
A progressive disease is defined as the worsening of subject condition caused by the primary tumor
that the investigational drug is targeting, the appearance of new lesions, or the progression of the
primary lesion. Expected progressive disease should not be reported as an AE. Any deaths, life-
threatening events, hospitalization or prolonged hospitalization, permanent or significant
disability/incapacity, congenital anomaly/birth defects, or other important medical events caused
by progressive disease should not be reported as an SAE
8 STATISTICS
8.1 Sample Size Determination
A number of 218 subjects for each group (436 subjects in total) can provide 80% test power to
confirm the clinical equivalence between the treatments of IBI305 in combination with
paclitaxel/carboplatin and bevacizumab in combination with paclitaxel/carboplatin.
The sample size is estimated based on the following assumptions:

The ORRs between IBI305 and bevacizumab group are equivalent

The ORR of subjects in the bevacizumab groups is set to 50.0%

The equivalence margin for the ratio of ORR is taken as (0.75, 1/0.75))

The significance level of the two one-side test is 0.05

1:1 randomization
Based on the above hypotheses, a number of 218 subjects for each group is required (436
subjects in total). The sample size was estimated using PASS 2013.
8.2 Statistical Population
Intention-to-Treat (ITT): All randomized subjects.
Full Analysis Set (FAS): All randomized and evaluable subjects who received at least one dose
of the study treatment. This dataset is used as the primary analysis set for efficacy assessment.
Per-Protocol (PP): Based on the FAS, subjects with the predetermined minimum drug exposure
and without any predetermined major protocol deviations. This dataset is used as the secondary
analysis set for efficacy assessment.

treatment and have safety evaluation data. This data set is used for the safety evaluation of this
study.
PK analysis set (PKAS): Includes subjects in the FAS with at least one PPK measured value.
Pharmacodynamic analysis set (PDAS): Includes all subjects in the FAS set with at least one PD
measured value.
8.3 General Principles for Statistical Analyses
For continuous variables, descriptive statistics should include the count, mean, standard
deviation, median, maximum, and minimum. For categorical variables, descriptive statistics will
include the number and percentage of each category. Statistical analyses will be carried out using
SAS 9.4.
8.4 Statistical Methods
8.4.1 Adjustments for covariates
The stratification factors of randomization in this study include age and EGFR status, and the
stratification factors will be considered in the model analysis (GLM or Cox) of primary and
secondary efficacy parameters
8.4.2 Managing dropouts and missing data
The handling of dropout and missing data will be detailed in the statistical analysis plan
8.4.3 Multi-center study
Since this is a multicenter study, the primary endpoint (ORR) will be listed according to study
sites and treatment groups. However, individual equivalence analysis will not be conducted.
Trial sites with fewer than 5 ITT subjects per treatment group will need to be combined for
analysis. Details will be discussed in the data review meeting.
8.4.4 Multiple comparisons and adjustments to multiplicity
The α adjustment for multiple comparisons is not considered.

8.5 Statistical Analyses
8.5.1 Subject distribution
Refer to Figure 1: Study design schematic for the schedule of activities. The number and
percentage of patients who have completed or dropped out of the study (including the reason for
dropouts such as loss to follow-up, AEs, and poor compliance) are summarized based on
treatment groups.
The number and percentage of subjects in each analysis set are calculated based on treatment groups.
The number and percentage of protocol deviations are calculated based on treatment groups.
8.5.2 Demographics and other baseline characteristics
Demographic information such as age, height, sex, and weight, and other baseline characteristics
such as disease history (including NSCLC diagnosis, staging, previous cancer treatment, and
target and nontarget lesions) are summarized using descriptive statistics.
8.5.3 Compliance and drug exposure
The required dose and the actual dose must be documented in the eCRF. Subject compliance is
calculated based on the ratio of the actual dose (number of doses) to the required dose (number
of doses). Subject compliance is classified into the following categories: < 80%, 80–120%, and >
120%. The number and percentage of subjects in each category will be summarized.
8.5.4 Efficacy
The efficacy analysis will be based on the FAS. Results of the PP set will also be presented.
8.5.4.1 Primary efficacy endpoint
The primary objective of this study is to determine the clinical equivalence between IBI305 +
paclitaxel/carboplatin and bevacizumab + paclitaxel/carboplatin for the treatment of advanced or
relapsed non-squamous non-small cell lung cancer (NSCLC). The primary endpoint is objective
response rate (ORR). ORR is defined as the incidence of confirmed complete response (CR) or
partial response (PR), using a validated imaging method to evaluate target lesions and non-target
lesions according to RECIST v1.1. Subjects without tumor assessments after baseline will be
considered as not assessable. Subjects qualified for the evaluation of CR or PR must have at least
one measurable lesion according to RECIST v1.1. The evaluation of clinical equivalence will be
based on the ORR provided by the independent review committee (IRC). Results provided by the

investigator will be used for sensitivity analysis.
Clinical equivalence will be determined by whether the 90% CIs of ORR ratio for subjects in
both IBI305 and bevacizumab groups falls within the equivalence margins of (0.75, 1/0.75).
The ORR and corresponding 95% confidence interval of the two treatment groups, the ORR
difference and the 90% confidence interval, as well as the ORR ratio between the two groups and
the 90% confidence interval will be estimated using the generalized linear model (GLM, which
includes treatment groups and stratification factors).
8.5.4.2 Secondary efficacy endpoints
The secondary endpoints for this study include DOR, DCR, progress-free survival (PFS), and
overall survival (OS).
DCR is defined as the incidence of patients with confirmed complete response (CR), partial
response (PR), and stable disease (SD), when a validated imaging method and RECIST v1.1 are
used to evaluate target and non-target lesions.
DOR is defined as the time from initial tumor response (CR or PR) to PD or death; Subjects with
CR or PR who do not progress or die will be censored on the date of the last tumor assessment.
OS refers to the time from the date of randomization to the date of death (of any cause). For
subjects who are still alive at the time of the analysis, their survival time is censored on the last
known alive date. PFS refers to the time from the date of randomization to the date of first
documented PD or death, whichever occurs first. Subjects who do not progress or die will be
censored on the date of the last tumor assessment. Subjects without tumor assessments after
baseline are censored on their date of randomization.
Median OS and its 95% CI will be estimated using the Kaplan-Meier method. The survival curve
will be plotted. The hazard ratio (HR) between the two groups and its 95% CI will be estimated
using a Cox model. The Cox model includes treatment groups and stratification factors. DOR
and PFS will be analyzed using the same method as for OS. DCR will be analyzed using the
same method for primary efficacy endpoints, but an equivalence test will not be conducted.
8.5.4.3 Sensitivity analysis
The center effect (fixed or random) will be considered in the primary and secondary endpoints
analysis models (GLM or Cox).
8.5.4.4 Antibody and efficacy analysis
Subjects who produce antibodies during the study will be listed. The difference in efficacy
between subjects with and without antibodies will be compared if necessary.

9 QUALITY ASSURANCE AND QUALITY CONTROL
According to GCP principles, the sponsor is responsible for implementing and maintaining
quality assurance and quality control systems based on standard operating procedures (SOP),
to ensure that the implementation of the clinical trial and the collection, documentation, and
reporting of trial data is in accordance with the protocol, GCP, and applicable regulatory
requirements.
To ensure that the data is reliable and processed correctly, there should be quality control for
every step during the data processing.
In addition, the Clinical Quality Assurance (CQA) Department of the sponsor and/or CRO may
conduct regular audits of the study process, including but not limited to auditing the study site,
on-site visits, central laboratory, suppliers, clinical database, and the final clinical study report.
Regulatory authorities may also conduct inspections during the trial or at any time after the trial
is completed. The investigator and the research institution must allow the sponsor's representative
and regulatory authorities to review source data.
9.1 Clinical Monitoring
The sponsor has authorized Wuxi Clinical Co., Ltd. to conduct clinical monitoring for this study.
The clinical research associate (CRA) should follow the SOPs of Wuxi Clinical Co., Ltd. when
carrying out monitoring, and has the same rights and responsibilities as the sponsor's monitor.
The CRA should maintain regular communication with the investigator and the sponsor.
Before the start of the study, the associate monitor assess the qualifications of each study site,
and report issues related to facilities, technical equipment, or medical staff to the sponsor. During

the study, the CRA will be responsible for confirming whether written informed consent is
obtained from all subjects, and whether data documentation is accurate and complete. At the
same time, the CRA will compare data entered in to the eCRF with source data, and notify the
investigator of any errors or omissions. The CRA will also verify protocol compliance of the
study site, as well as the dispensing and storage of investigational drugs to ensure protocol
requirements are met.
The monitoring visit will be conducted in accordance with applicable statutes and regulations.
Each site receives regular monitoring visits from the time the subjects are enrolled. The CRA
should submit a written report to the sponsor after each monitoring visit to the study site.
9.2 Data Management/Coding
The Data Management and Biostatistics Department of Wuxi Clinical Co., Ltd will process data
generated from this study in accordance with relevant SOPs.
This study will use an electronic data capture (EDC) system. Trial data will be entered into the
eCRF by the investigator or authorized study personnel. Prior to launching of the study site or
data entry, the investigator and authorized study personnel will receive appropriate training, and
appropriate safety measures will be taken.
All data are input in Chinese. The eCRF should be completed during or soon after each visit, and
should be constantly updated to ensure that it reflects the latest status of the subject. To avoid
discrepancies in outcome assessments between different evaluators, ensure that baseline and all
subsequent efficacy and safety assessments for the same subject are performed by the same
person. The investigator must review trial data to ensure the accuracy and correctness of all data
entered into the eCRF. During the study, the investigator should document any evaluations that
are not conducted, or any information that is not available, applicable, or known. The
investigator needs to sign all verified data electronically.
The CRA will review the eCRF, and evaluate its completeness and consistency. The CRA will
also compare the eCRF with the source documents to ensure the consistency of critical data. Data
entry, corrections, or modifications are completed by the investigator or designated staff. The
CRA do not have access to data entry. The data in eCRF is submitted to the data server, and any
changes to the data will be documented in the audit trail, including the reason for the change, the
name of the operator, as well as the time and date of the change. The roles and permissions of
study personnel responsible for data entry will be predetermined. The CRA or data manager will
submit data queries in the EDC system, and study personnel shall respond to the queries. The
EDC system will record the audit trail of each query, including the name of the investigator, as
well as the time and date.

Unless otherwise specified, the eCRF should be considered simply as a form for data collection
and not a source document. A source file is used by the investigator or hospital, relevant to the
subject, and can prove the existence of the subject, inclusion criteria, and all records of
participation in the study, including laboratory records, ECG results, memorandum, pharmacy
dispensing records, and subject folders.
The investigators are required to maintain all source documents and to offer the documents to the
CRA for review during each visit. In addition, the investigator must submit a complete eCRF for
each subject, regardless of the duration of the subject's participation in the study. The study
number and subject number in all supporting documents (such as laboratory records or hospital
records) submitted along with the eCRF should be carefully verified. All personal privacy
information (including the name of the subject) should be deleted or be made indecipherable in
order to protect subject privacy.
The investigator could be automatically added to the eCRF with his/her user ID. The investigators
verify that the record have been reviewed and that the data are accurate with an electronic
signature. The electronic signature is completed with the investigator's user ID and password.
The system automatically attaches the date and time of the signature. The investigator could not
share the user ID and password with other personnel. If data in the eCRF need to be modified,
the procedures defined by the EDC system have to be followed. All modifications and reasons
for the changes are recorded in the audit trail.
Training on the EDC system will be provided to study personnel at the study site.
Adverse events, and concurrent diseases/medical history will be coded. The medical dictionary
used for coding will be described in the Clinical Study Report (CSR).
9.3 Audits and Inspections
The sponsor or its representative (WuXi Clinical Co., Ltd) may conduct quality assurance audits
on the study site, database, and relevant study-related documents. Also, regulatory authorities
may also decide to inspect the study site, database, and relevant study-related documents at its
own discretion. The aim of audits and inspections is to systematically and independently check
all study-related procedures and documents to ensure that the clinical study is being carried out
in accordance with requirements of the trial protocol, GCP, Declaration of Helsinki, and
applicable regulations. The investigator must inform the sponsor immediately when an
inspection notice is received from the regulatory authorities.

document the informed consent process in the source document of the trial.
10.4 Protection of Subject Data
Information about data protection and privacy protection will be included in the ICF (or in some
cases, in a separate document).
Study personnel must ensure that the privacy of clinical trial subjects are protected. In all
documents submitted to the sponsor, the clinical trial subjects must only be identified with
subject number and not with the full name.
Additional precautions should be taken to ensure the confidentiality of the documents and
to prevent the identification of subjects based on genetic data. However, under special
circumstances, some personnel may be permitted to see the genetic data and personal
identification number of a subject. For example, in the event of a medical emergency, the
sponsor, designated physician, or investigator will have access to the subject identification code
and the subject's genetic data. In addition, regulatory agencies may request access to relevant
documents.

MEASURABILITY OF TUMOR AT BASELINE
1.1
Definitions
At baseline, tumor lesions/lymph nodes will be categorized as measurable or not measurable as
follows:
1.1.1
Measurable
Tumor lesions: must be accurately measured in at least one dimension (longest diameter in the
plane of measurement is to be recorded) with a minimum size of:

10 mm by CT scan (CT scan slice thickness no greater than 5 mm)

10 mm caliper measurement by clinical exam (lesions which cannot be accurately
measured with calipers should be documented as not measurable).

20 mm by chest X-ray.
Malignant lymph nodes: To be considered pathologically enlarged and measurable, a lymph
node must be ≥15 mm in short axis when assessed by CT scan (CT scan slice thickness
recommended to be no greater than 5 mm). At baseline and in follow-up, only the short axis will
be measured and followed.
1.1.2
Not measurable
All other lesions, including small lesions (longest diameter <10 mm or pathological lymph nodes
with a short axis ≥10 and <15 mm) as well as truly not measurable lesions. Lesions considered
truly not measurable include: leptomeningeal disease, ascites, pleural or pericardial effusion,
inflammatory breast disease, lymphangitis involving the skin or lungs, abdominal masses/
abdominal organomegaly identified by physical exam but not measurable by reproducible
imaging techniques.
1.1.3
Special considerations regarding measurable bone lesions, cystic lesions, and lesions
with prior locoregional treatment:
Bone lesions:

Bone scan, PET scan or plain films are not considered adequate imaging
techniques to measure bone lesions. However, these techniques can be used to
confirm the presence or disappearance of bone lesions.


Lytic bone lesions or mixed lytic-blastic lesions, with identifiable soft tissue
components, that can be evaluated by cross sectional imaging techniques (such as
CT or MRI) can be considered as measurable lesions if the soft tissue
components meet the definition of measurability described above.

Blastic bone lesions are not measurable.
Cystic lesions:

Lesions that meet the criteria for radiographically defined simple cysts should not
be considered as malignant lesions (neither measurable nor not measurable) since
they are, by definition, simple cysts.

‘Cystic lesions’ thought to represent cystic metastases can be considered as
measurable lesions, if they meet the definition of measurability described above.
However, if noncystic lesions are present in the same patient, these noncystic
lesions are preferred for selection as target lesions.
Lesions with prior locoregional treatment:

Tumor lesions situated in a previously irradiated area or in an area subjected to
other locoregional therapy are usually not considered measurable, unless there
has been demonstrated progression in the lesion. The study protocol should detail
the conditions under which such lesions would be considered measurable.
1.2
Specifications by Methods of Measurements
1.2.1
Measurement of lesions
All measurements should be documented with metric symbols. Calipers should be used if clinical
assessments are required. All baseline evaluations should be performed as close as possible to
the beginning of the treatment but never more than 4 weeks before the beginning of the treatment.
1.2.2
Method of assessment
The same method of assessment and the same technique should be used to characterize each
identified and reported lesion at baseline and during follow-up. Imaging evaluation should
always be done rather than clinical examination unless the lesion(s) being followed cannot be
imaged but are assessable by clinical examination.
Clinical lesions: Clinical lesions will only be considered measurable when they are superficial
and its diameter is ≥10 mm as assessed using calipers (e.g. skin nodules). For skin lesions,
documentation by color photography including a plotting scale to estimate the size of the lesion
is recommended. As noted above, when lesions can be evaluated by both clinical examination
and imaging evaluation, the latter should be undertaken since it is more objective and may also

be reviewed at the end of the study.
Chest X-ray: Chest CT is preferred over chest X-ray, particularly when progression is an
important endpoint, since CT is more sensitive than X-ray, particularly in identifying new lesions.
However, lesions on chest X-ray may be considered measurable if they have clear boundaries
and are surrounded by aerated lung tissues.
CT and MRI: CT is the best currently available and reproducible method to measure lesions
selected for response assessment. This guideline has defined measurability of lesions on CT scan
based on the assumption that CT slice thickness is 5 mm or less. When CT scans have a slice
thickness greater than 5 mm, the minimum size for a measurable lesion should be twice the slice
thickness. MRI is also acceptable in certain situations (e.g. for body scans).
Ultrasound: Ultrasound should not be used for measuring lesion size and should not be used as
a method of measurement. Ultrasound examinations cannot be reproduced in their entirety for
independent review at a later date and, because they are operator dependent, it cannot be
guaranteed that the same technique and measurements will be taken from one assessment to the
next. If new lesions are identified by ultrasound in the course of the study, confirmation by CT
or MRI is recommended. If there is concern about radiation exposure at CT, MRI may be used
instead of CT in selected instances.
Endoscopy and laparoscopy: The utilization of these techniques is not recommended for
objective tumor evaluation. However, they can be used to confirm complete pathological
response when biopsies are obtained or to determine relapse in trials where recurrence following
complete response or surgical resection is an endpoint.
Tumor markers: Tumor markers alone cannot be used to assess objective tumor response. If
markers are initially above the upper limit of normal, however, they must normalize for a patient
to be considered in complete response. Because tumor markers are disease specific, instructions
for their measurement should be incorporated into the protocol on a disease specific basis.
Specific guidelines for both CA-125 response (in recurrent ovarian cancer) and PSA response
(in recurrent prostate cancer) have been published. In addition, the Gynecologic Cancer
Intergroup has developed CA125 progression criteria which are to be integrated with objective
tumor assessment for use in first-line trials in ovarian cancer.
Cytology and histology: These techniques can be used to differentiate between PR and CR in rare
cases if required by the protocol (for example, residual lesions in tumor types such as seminoma,
where known residual benign tumors can remain). When effusions are known to be a potential
adverse effect of treatment (e.g. with certain taxane compounds or angiogenesis inhibitors),
cytological confirmation of the neoplastic origin of any effusion that appears or worsens during

treatment can be considered if the measurable tumor has met criteria for response or stable
disease in order to differentiate between response (or stable disease) and progressive disease.
2.
TUMOR RESPONSE EVALUATION
2.1
Assessment of Overall Tumor Burden and Measurable Disease
To assess objective response or future progression, it is necessary to estimate the overall tumor
burden at baseline and use this as a comparator for subsequent measurements. Only patients with
measurable disease at baseline should be included in regimens where objective tumor response is
the primary endpoint. Measurable disease is defined by the presence of at least one measurable
lesion. In studies where the primary endpoint is tumor progression (either time to progression or
proportion with progression at a fixed date), the protocol must specify if entry is restricted to
those with measurable disease or whether patients having non-measurable disease only are also
eligible.
2.2
Baseline Documentation of "Target" and "Non-Target" Lesions
When more than one measurable lesion is present at baseline, all lesions (five lesions at most,
and two lesions per organ at most) representative of all involved organs should be identified as
target lesions and will be recorded and measured at baseline (This means in instances where
patients have only one or two organ sites involved, a maximum of two and four lesions
respectively will be recorded).
Target lesions should be selected on the basis of their size (lesions with the longest diameter), be
representative of all involved organs, and should be those with reproducible repeated
measurements. It may be the case that, the largest lesion does not have reproducible
measurements, in which circumstance the next largest lesion with reproducible measurements
should be selected.
Lymph nodes merit special mention since their normal anatomical structures may be visible by
imaging even if not involved by tumor. Pathological nodes which are defined as measurable and
may be identified as target lesions must have a short axis of ≥15 mm by CT scan. Only the short
axis of these nodes will contribute to the baseline sum. The short axis of the node is the diameter
normally used by radiologists to judge if a node is invaded by solid tumor. Nodal size is
normally reported as two dimensions in the plane in which the image is obtained (for CT scan
this is almost always the axial plane; for MRI the plane of acquisition may be axial, sagittal or
coronal). The smaller of these measures is the short axis. For example, an abdominal node which
is reported as being 20 mm × 30 mm has a short axis of 20 mm and qualifies as a malignant
measurable node. In this example, 20 mm should be reported as the node measurement. All other
pathological nodes (those with a short axis ≥10 mm but < 15 mm) should be considered non-

target lesions. Lymph nodes that have a short axis < 10 mm are considered non-pathological and
should not be recorded or followed.
A sum of the diameters (longest for non-nodal lesions; short axis for nodal lesions) for all target
lesions will be calculated and reported as the baseline sum of diameters. If lymph nodes are to be
included in the sum, then as noted above, only the short axis is added into the sum. The baseline
sum of diameters will be used as reference to further characterize any objective tumor regression
in the measurable dimension of the disease.
All other lesions (or sites of disease) including pathological lymph nodes should be identified as
non-target lesions and should also be recorded at baseline. Measurements are not required and
these lesions should be recorded as "present", "absent", or in rare cases "unequivocal
progression". In addition, it is possible to record multiple target lesions involving the same organ
as a single item on the case record form (e.g. ‘multiple enlarged pelvic lymph nodes’ or ‘multiple
liver metastases’).
2.3
Response Criteria
2.3.1
Evaluation of target lesions
Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes
(whether target or non-target) must have a reduced short axis of <10 mm.
Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions vs. the
baseline sum of diameters.
Progressive Disease (PD): At least a 20% increase in the sum of diameters of target lesions vs.
the smallest sum during the study (this includes the baseline sum if that is the smallest). In
addition to the relative increase of 20%, the sum must also have an absolute increase of at least
5 mm. (Note: The appearance of one or more new lesions is also considered progression).
Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to
qualify for PD, using the smallest sum of diameters during the study as reference.
2.3.2
Special notes on the assessment of lymph nodes which are target lesions
Lymph nodes identified as target lesions should always have the actual short axis measurement
recorded (measured in the same anatomical plane as during the baseline examination), even if the
nodes regress to below 10 mm at the time of the study. This means that when lymph nodes are
included as target lesions, the "sum" of lesions may not be zero even if complete response
criteria are met, since a normal lymph node is defined as having a short axis of <10 mm. Case
report forms or other data collection methods may therefore be designed to have target nodal
lesions recorded in a separate section where, in order to qualify for CR, each node must have a

short axis of <10 mm. For PR, SD, and PD, the actual short axis measurement of the nodes is to
be included in the sum of target lesions.
Target lesions that are "too small to measure". During the study, all lesions (nodal and non-
nodal) recorded at baseline should have their actual measurements recorded at each subsequent
evaluation, even when very small (e.g. 2 mm). However, sometimes lesions or lymph nodes
which are recorded as target lesions at baseline become so faint on CT scan that the radiologist
may not feel comfortable assigning an exact measurement and may report them as being "too
small to measure". When this occurs it is important that a value be recorded on the case report
form. If it is the opinion of the radiologist that the lesion has probably disappeared, the
measurement should be recorded as 0 mm. If the lesion is believed to be present and is faintly
seen but too small to measure, a default value of 5 mm should be assigned (Note: It is less likely
that this rule will be used for lymph nodes since they usually have a definable size when normal
and are frequently surrounded by fat such as in the retroperitoneum; however, if a lymph node is
believed to be present and is faintly seen but too small to measure, a default value of 5 mm
should be assigned in this circumstance as well). This default value is derived from the 5 mm CT
slice thickness (but should not be changed with varying CT slice thickness). The measurements
of these lesions are potentially non-reproducible, therefore providing this default value will
prevent false responses or progressions caused by measurement errors. To reiterate, however, if
the radiologist is able to provide an actual measurement, that value should be recorded, even if it
is below 5 mm.
Lesions that split or coalesced at the time of treatment. When non-nodal lesions fragment, the
longest diameters of the fragmented portions should be added together to calculate the target lesion sum.
Similarly, as lesions coalesce, a plane between them may be maintained that would aid in obtaining
maximal diameter measurements of each individual lesion. If the lesions have truly coalesced such that
they are no longer separable, the vector of the longest diameter in this instance should be the maximal
longest diameter for the "coalesced lesion".
2.3.3
Evaluation of non-target lesions
This section provides the definitions of the criteria used to determine the tumor response for the
group of non-target lesions. While some non-target lesions may actually be measurable, they do
not need to be measured and instead should be assessed only qualitatively at the time points
specified in the protocol.
Complete Response (CR): Disappearance of all non-target lesions and normalization of tumor
marker level. All lymph nodes must be non-pathological in size (short axis <10 mm).
Non-CR/Non-PD: Persistence of one or more non-target lesion(s) and/or maintenance of tumor
marker level above the normal limits.

Progressive Disease (PD): Unequivocal progression of existing non-target lesions. (Note: The
appearance of one or more new lesions is also considered progression).
2.3.4
Special notes on the assessment of progression of non-target lesions
The concept of progression of non-target disease requires additional explanation as follows: When
the patient also has measurable lesions. In this setting, to achieve ‘unequivocal progression’ on the
basis of the non-target lesion, there must be an overall level of substantial worsening in non-target
disease such that, even in the presence of SD or PR of the target disease, the overall tumor burden
has increased sufficiently to merit discontinuation of therapy. A minimal increase in the size of one
or more non-target lesions is usually not sufficient to quality for unequivocal progression status.
The designation of overall progression solely on the basis of change in non-target lesions in the
face of SD or PR of target disease will therefore be extremely rare.
When the patient has only lesions that are not measurable. This circumstance arises in some
phase III trials when the presence of measurable lesions is not a criterion for study enrollment.
The same general concepts apply here as well. However, in this instance there are no measurable
lesions to factor into the interpretation of an increase in non-measurable lesion burden. Because
worsening in non-target lesion cannot be easily quantified (by definition: if all lesions are truly
not measurable), a useful test that can be applied when assessing patients for unequivocal
progression is to consider if the increase in overall lesion burden based on the change in non-
measurable disease is comparable in magnitude to the increase that would be required to declare
PD for measurable disease: i.e. an increase in tumor burden representing an additional 73%
increase in volume (which is equivalent to a 20% increase of diameter in a measurable lesion).
Examples include an increase in pleural effusion from "trace" to "large amount", an increase in
lymphangitic lesion from localized to widespread, or a description in the protocol such as
"sufficient to require a change in therapy". If ‘unequivocal progression’ is seen, the patient
should be considered to have had overall PD at that point. While it would be ideal to have
objective criteria to apply to diseases that are not measurable, the very nature of these diseases
makes it impossible to do so, therefore the increase must be substantial.
2.3.5
New lesions
The appearance of new malignant lesions denotes disease progression; therefore, some
comments on the detection of new lesions are important. There are no specific criteria for the
identification of new radiographic lesions; however, the finding of a new lesion should be
unequivocal: i.e. not attributable to differences in scanning technique, change in imaging
modality or findings thought to represent something other than tumors (for example, some new
bone lesions which may be simply healed or flare of pre-existing lesions). This is particularly

important when the patient’s baseline lesions show partial or complete response. For example,
necrosis of a liver lesion may be reported by a CT scan as a "new" cystic lesion, while it is
actually not.
A lesion identified during a follow-up in an anatomical location that is not discovered during the
baseline scan is considered a new lesion and will indicate disease progression. For example, a
patient with a visceral disease at baseline has a brain CT or MRI which reveals metastases. The
patient's brain metastases are considered evidence of PD even if he/she does not have brain
imaging at baseline.
If a new lesion is equivocal, for example because of its small size, continued therapy and follow-
up evaluation will clarify if it represents a truly new lesion. If repeat scans confirm there is
definitely a new lesion, then progression should be declared using the date of the initial scan.
While FDG-PET response assessments need additional studies, it is sometimes reasonable to
incorporate the use of FDG-PET scanning to complement CT scanning in assessment of
progression (particularly possible "new" lesions). New lesions on the basis of FDG-PET imaging
can be identified as follows:
a.
A negative FDG-PET at baseline and a positive FDG-PET at follow-up is a sign of PD
based on a new lesion.
b.
No FDG-PET at baseline and a positive FDG-PET at follow-up:
If the positive FDG-PET at follow-up corresponds to a new lesion site confirmed by
CT, this is PD. If the positive FDG-PET at follow-up is not confirmed as a new lesion
site on CT, additional follow-up CT scans are needed to determine if there is truly
progression at that site (if so, the date of PD will be the date of the initial abnormal
FDG-PET scan). If the positive FDG-PET at follow-up corresponds to a pre-existing
lesion site on CT that is not progressing according to the anatomic images, this is not PD.
2.4
Evaluation of Best Overall Response
The best overall response is the best response recorded from the start of the study treatment until
the end of treatment, taking into account any requirement for confirmation. On occasion a
response may not be documented until after the end of therapy, so the study protocol should
clearly state if post-treatment assessments are to be considered when determining best overall
response. The study protocol must specify how any new therapy introduced before progression
will affect best response designation. Assignment of best overall response for the patient will
depend on the findings of both target and non-target lesions and will also take into consideration
the appearance of new lesions. Furthermore, depending on the nature of the study and the

protocol requirements, confirmatory measurement may also be required. Specifically, in non-
randomized trials where response is the primary endpoint, confirmation of PR or CR is needed to
determine which one is the "best overall response".
2.4.1
Time point response
It is assumed that at each time point specified by the study protocol, a response assessment
occurs. Table 1 on the next page provides a summary of the overall response status calculation at
each time point for patients who have measurable disease at baseline.
When patients have non-measurable (therefore non-target) disease only, Table 2 is to be used.
2.4.2
Missing assessments and non-evaluable targets
When no imaging/measurement is done at a particular time point, the patient is not evaluable
(NE) at that time point. If only a subset of lesion measurements is made at an assessment, usually
the case is also considered NE at that time point, unless a convincing argument can be made that
the missing lesion(s) would not change the response at the assigned time point. This would be
most likely to happen in the case of PD. For example, if a patient has a baseline sum of 50 mm
with three measured lesions and at follow-up only two lesions are assessed and with a sum of 80
mm, the patient will have achieved PD status, regardless of the contribution of the missing lesion.
2.4.3
Best overall response: all time points
The best response is determined once all the data for the patient is obtained.
Best response determination in trials where confirmation of complete or partial response is not
required: Best response in these trials is defined as the best response across all time points (for
example, the best overall response of a patient who has SD at the first assessment, PR at the
second, and PD at the last is PR). When SD is believed to be best response, it must also meet the
minimum time from baseline specified by the protocol. If the minimum time is not met,
otherwise SD is the best time point response, the patient’s best response depends on subsequent
assessments. For example, if a patient has SD at the first assessment, PD at the second and does
not meet the minimum duration for SD, his/her best response is PD. The same patient lost to
follow-up after the first SD assessment would be considered not evaluable.
Best response determination in trials where confirmation of complete or partial response is
required: Complete or partial responses may be claimed only if the criteria for each are met at a
subsequent time point specified in the protocol (generally 4 weeks later). In this circumstance,
the best overall response can be interpreted as in Table 3.

2.4.4
Special notes on response assessment
When nodal lesions are included in the sum of target lesions and the nodes decrease to "normal"
size (<10 mm), they may still have a measurement reported on scans. This measurement should
be recorded even if the nodes are normal in size in order not to overstate progression should it be
based on the increase in size of the nodes. As noted earlier, this means that patients with CR may
not have a total sum of "zero" on the case report form (CRF).
In trials where confirmation of response is required, repeated "NE" time point assessments may
complicate best response determination. The analysis plan for the trial must explain how missing
data/assessments will be addressed in the determination of response and progression. For
example, in most trials it is reasonable to consider a patient with time point responses of PR-NE-
PR as a confirmed response.
Patients with a global deterioration of health status requiring discontinuation of treatment without
objective evidence of disease progression at that time should be reported as "symptomatic
deterioration". Every effort should be made to document objective progression even after
discontinuation of treatment. Symptomatic deterioration is not a descriptor of an objective
response. Instead, it is a reason for stopping the study treatment. The objective response status of
this type of patients is to be determined by evaluation of target and non-target lesions as shown
in Table 1–3.
Conditions that define "early progression, early death, and non-evaluability" are study specific
and should be clearly described in each study protocol (depending on treatment duration and
treatment periodicity).
In some circumstances it may be difficult to distinguish a residual lesion from normal tissues.
When the evaluation of complete response depends upon this determination, it is recommended
that the residual lesion be investigated (by fine needle aspirate/biopsy) before assigning a status
of complete response.
Like a biopsy, FDG-PET may also be used to upgrade a response to a CR in cases where a
residual radiographic abnormality is thought to represent fibrosis or scarring. The use of FDG-
PET in this circumstance should be pre-defined in the protocol and supported by disease specific
medical literature for the indication. However, it must be acknowledged that both approaches
may lead to false positive CR due to limitations of FDG-PET and biopsy resolution/sensitivity.

a "Non-CR/non-PD" is preferred over "stable disease" for non-target disease, since SD is increasingly used as an
endpoint for assessment of efficacy in some trials, thus assigning this category in the absence of measurable
lesions is not advised.
For equivocal findings of progression (e.g. very small and uncertain new lesions; cystic changes
or necrosis in existing lesions), treatment may continue until the next scheduled assessment. If at
the next scheduled assessment, progression is confirmed, the date of progression should be the
earlier date when progression is suspected.

a If CR is truly achieved at the first time point, then any lesions seen at a subsequent time point, even those meeting
PR criteria relative to baseline, make the disease PD at that time point (since lesions must have reappeared after
CR). Best response would depend on whether the minimum duration for SD is met. However, sometimes CR may
be claimed and subsequent scans suggest small lesions are likely still present, while in fact the patient have PR
instead of CR at the first time point. Under these circumstances, CR should be changed to PR and the best response
is PR.
2.5 Frequency of Tumor Re-Evaluation
Frequency of tumor re-evaluation during treatment should be protocol specific and adapted to the
type and schedule of treatment. However, for phase II studies where the beneficial effect of the
treatment is not known, follow-up every 6–8 weeks (timed to coincide with the end of a cycle) is
reasonable. Smaller or greater time intervals may be justified for certain regimens or circumstances.
The study protocol should specify which organ sites are to be evaluated at baseline (usually those
most likely to be involved with metastatic disease for the tumor type under study) and how
often evaluations are repeated. Normally, all target and non-target sites are evaluated at each
assessment. Under certain circumstances, some non-target organs may be evaluated less frequently.
For example, bone scans may need to be repeated only when complete response is identified in
the target lesion or when progression is suspected.

After the end of the treatment, the need for repeated tumor evaluations depends on whether the
trial has a goal such as a certain response rate or a certain time to an event (progression/death).
If ‘time to an event’ (e.g. time to progression, disease-free survival, progression-free survival) is
the main endpoint of the study, then routine scheduled re-evaluation of lesion sites specified by
the protocol must be carried out. In randomized comparative trials in particular, the scheduled
assessments should be performed on time (for example: every 6–8 weeks during the treatment or
every 3–4 months after the treatment) and should not be affected by treatment delays, holidays or
any other events that might lead to imbalance in the timing of disease assessment between
treatment arms.
2.6 Confirmation of Measurements/Duration of Response
2.6.1 Confirmation
In non-randomized trials where response is the primary endpoint, confirmation of PR and CR is
required to ensure responses identified are not the result of measurement errors. This will also
permit appropriate interpretation of results in the context of historical data. Response
confirmation has been traditionally required in such trials. However, in all other circumstances,
i.e. in randomized trials (phase II or III) or studies where stable disease or progression are the
primary endpoints, confirmation of response is not required since it will not add value to the
interpretation of trial results. However, elimination of the requirement for response confirmation
may increase the importance of central review to protect against bias, in particular in studies
which are not blinded.
In the case of SD, measurements after study entry must have met the minimum interval for SD
(generally not shorter than 6–8 weeks) defined in the study protocol at least once.
2.6.2 Duration of overall response
The duration of overall response is measured from the time CR/PR measurement criteria are first
met CR/PR (whichever is first documented) until the date when recurrent or progressive disease
is objectively documented for the first time (using the shortest time to progressive disease
documented during the study as reference).
The duration of overall complete response is measured from the time CR measurement criteria
are first met until the date when recurrent disease is objectively documented for the first time.
2.6.3 Duration of stable disease
Stable disease is measured from the start of the treatment (in randomized trials, from the date
of randomization) until the criteria for progression are met, using the smallest sum during the
study as reference (if the baseline sum is the smallest, then it is used as the reference for the
calculation of PD).

The clinical relevance of the duration of stable disease varies with different studies and diseases.
If the proportion of patients achieving stable disease for a minimum period of time is an endpoint
of importance in a particular trial, the protocol should specify the minimal time interval required
between two measurements for the determination of stable disease.
Note: The duration of response and stable disease as well as the progression-free survival are
influenced by the frequency of follow-up after baseline evaluation. It is not in the scope of the
guidelines to define a standard follow-up frequency. The frequency should take into account
many parameters including disease types and stages, treatment periodicity, and standard practice.
However, limitations of the precision of the measured endpoint should be taken into account if
comparisons between trials are to be made.


To compare the PD of IBI305 and bevacizumab in subjects with advanced or recurrent non-squamous
NSCLC
Study design:
This is a randomized, double-blinded, multi-center phase III study. The study planned to enroll and randomize 436
subjects with non-squamous NSCLC in a 1:1 ratio to IBI305 plus paclitaxel/carboplatin group or bevacizumab plus
paclitaxel/carboplatin group. Stratifying factors include age (< 60 vs. ≥60 years old) and EGFR status (wild type vs.
unknown type).
Each treatment cycle is 3 weeks for both groups. 15 mg/kg IBI305 or bevacizumab is administered on D1 of each
cycle along with paclitaxel/carboplatin. Subjects will receive up to 6 treatment cycles of combination therapy until
PD, unacceptable toxicity, withdrawal of informed consent, loss to follow-up, or death (whichever comes first).
Then subjects receive maintenance monotherapy, that is, discontinuing paclitaxel/carboplatin while continuing
therapy with IBI305 or bevacizumab. The maintenance monotherapy continues every 3 weeks. On D1 of each
treatment cycle, subjects will be administered 7.5 mg/kg of either IBI305 or bevacizumab until PD, unacceptable
toxicity, withdrawal of informed consent, loss to follow-up, death, or end of study (whichever comes first).
During the study, a CT or an MRI will be performed every 6 weeks (± 7 days) and be determined whether the study
treatment will be continued by investigators at each site through tumor assessments until PD, withdrawal of informed
consent, lost to follow-up, death, start of other anti-tumor therapies, or end of study. If subjects discontinue the study
treatment for reasons other than PD, tumor assessments will be continued until PD, withdrawal of informed consent, loss
of follow-up, death, start of other anti-tumor therapies, or end of study. If subjects discontinue the study treatment for PD,
the investigators will make telephone follow-up every 12 weeks (± 7 days) to collect information of subsequent anti-tumor
therapies and survival until withdrawal of informed consent, lost to follow-up, death, or end of study.

Statistical methods:
Sample size calculation:
A number of 218 subjects for each group (436 subjects in total) can provide 80% test power to confirm the clinical
equivalence between the treatments of IBI305 in combination with paclitaxel/carboplatin and bevacizumab in
combination with paclitaxel/carboplatin. Estimation parameters for sample size: The significance level of the two-
sided test is 0.05, the ORR of subjects in the IBI305 and bevacizumab groups is about 50.0%, and the equivalence
margin for the ratio of ORR is taken as (0.75, 1/0.75). Based on the above hypothesis, each group requires 218
subjects (436 subjects in total).
Efficacy analysis:
Clinical equivalence will be determined by whether the 90% confidence interval (CI) of the ratio of ORR between
the IBI305 and bevacizumab arms falls within the preset margin of (0.75, 1/0.75). The ORR and 95% CI of two
groups, ORR difference and 90% CI, and ORR ratio and 90% CI will be estimated using the generalized linear
model (GLM, including groups and stratification factors).
Median survival (OS) and survival curves will be estimated using the Kaplan-Meier method. The hazard ratio (HR)
and 95% CI of two groups will be estimated using the Cox model. DORs and PFSs will be analyzed by the same
method as the median survivals. DCR will be analyzed using the same method for primary efficacy endpoints, but
an equivalence test will not be conducted.
Safety analysis:
All adverse events (AE) will be coded using MedDRA and graded according to CTCAE v4.03. All treatment-
emergent adverse events (TEAEs), Grade 3 or greater TEAEs, serious adverse events (SAEs), investigational drug-
related TEAEs, investigational drug-related SAEs, TEAEs leading to treatment discontinuation, TEAEs leading
to study termination, and adverse events of special interest (AESIs) will be listed based on system organ class,
preferred terms, and groups and the numbers of corresponding subjects and percentages will be summarized.
In addition, the severity of TEAEs and the correlation with the study drug will also be summarized by system
organ class, preferred terms, and treatment groups.
Measured values and changes from baseline for vital signs, physical examination, laboratory tests and 12-lead ECG
will be analyzed using descriptive statistics. Baseline results and worst results during the study will be presented in
cross tabulation.
The number and percentage of subjects who developed anti-drug antibodies and neutralizing antibodies during the
study will be summarized by treatment group.
PK/PD exploratory analysis:
Mainly based on description, and inter-group comparison will be carried out if necessary

a.
After completing the on-site end-of-treatment visit 28 days after the last dose, subjects who discontinue the
investigational drug treatment due to reasons other than PD should continue to undergo tumor assessments once
every 6 weeks (±7 days) until PD (and begin post-PD follow-up thereafter), withdrawal of consent, start of another
antineoplastic treatment, loss to follow-up, death, or study completion.
b.
For subjects with PD, collect survival information once every 12 weeks (84 days, ±7 days) by phone until death,
loss to follow-up, withdrawal of informed consent, or study completion. Subsequent antineoplastic treatments
should be documented in the eCRF.
c.
Only measure weight.
d.
Clinical laboratory tests are carried out at the laboratory of each hospital. If screening laboratory tests (routine
blood test, blood chemistry, and urinalysis) are performed within 7 days prior to the first dose, the screening
results may be used as baseline data. For subsequent visits, all laboratory tests have to be completed within 3
days prior to the dose administration.
e.
A urinalysis is required before each IBI305/bevacizumab infusion to test urine protein.
f.
Women of childbearing age should undergo a serum/urine pregnancy test.
g.
Immunogenicity tests will be performed in all subjects at 3 blood sampling time points: Within 1 hour prior to
the first dose of the study treatment (IBI305/bevacizumab) in C1, within 1 hour prior to the administration of
the study treatment in C4, and during the end-of-treatment visit. Blood specimens that are positive for anti-drug
antibodies (ADA) after dosing will be further tested for neutralizing antibodies (NAb). Samples will be tested
at the designated central laboratory.
h.
Image assessments (CT or MRI) of the brain, chest, abdomen, and pelvis should be completed at baseline. If
these tests are performed within 28 days prior to the first dose of the study drug, they do not need to be repeated
unless the investigator believes that there have been changes in the subject's tumor burden. After the start of
treatment, imaging tests are performed once every 6 weeks (±7 days) and have to be completed within 7 days
prior to the scheduled visits, until progressive disease, start of other treatment, withdrawal of informed consent,
loss to follow-up, death, or study completion. The same method of imaging test is used at baseline and during
follow-up. Imaging evaluations of the chest, abdomen, and pelvis are required.
i.
All subjects should undergo tumor tissue EGFR testing.

j.
Each treatment cycle of the investigational product contains 3 weeks. The dose of IBI305 or bevacizumab is 15
mg/kg when used in combination with chemotherapeutic drugs and 7.5 mg/kg in the maintenance monotherapy,
given on D1 of every treatment cycle until progressive disease (PD), unacceptable toxic reactions, withdrawal
of informed consent, loss to follow-up, death, or end of study, whichever occurs first. After all assessments
were completed, the study drug was administered followed by chemotherapy. The first dose of study drug was
completed within 24 h after randomization.
k.
Each treatment cycle is 3 weeks long. Chemotherapy (paclitaxel + carboplatin) is administered on D1 of each
cycle for up to 6 cycles, or until disease progression (PD), unacceptable toxicity, withdrawal of informed
consent, loss to follow-up, or death. Paclitaxel is administered after the infusion of study drug is completed,
followed by carboplatin.

1 INTRODUCTION
1.1 Study Background
1.1.1 Disease background
Lung cancer has the highest incidence and mortality globally among all cancers. According to
the 2012 Global Cancer Statistics (GLOBOCAN 2012) published by International Agency for
Research on Cancer, there were approximately 1.8 million new lung cancer cases worldwide,
which accounted for 13% of the global newly-diagnosed cancers, and 58% of these cases
occurred in underdeveloped areas1. According to the data released by the National Central
Cancer Registry of China in 2015, lung cancer was the most prevalent malignancy in China in
2011, with about 650,000 new cases every year. Lung cancer was also the leading cause of death,
with about 520,000 deaths per year2. The limited clinical treatment of lung cancer is the main
reason for its poor prognosis. There is a huge demand for new types of lung cancer treatment
drugs.
Approximately 85–90% of lung cancers are non-small cell lung cancer (NSCLC) and patients
with NSCLC are usually in the advanced stages when diagnosed3. According to the Chinese
guidelines for the diagnosis and treatment of primary lung cancer, anatomic pulmonary resection
is the mainstay of treatment for early stage lung cancers4. However, despite surgery, some
patients develop distance metastases that eventually lead to death5. Surgery is not possible for
most patients with clearly diagnosed stage IIIB and IV as well as some patients with stage IIIA
NSCLC4. Comprehensive treatment based on systemic therapy is used to maximize patient
survival, control progressive disease, and improve the quality of life6.
In recent years, anti-tumor therapies have entered a new era with the emergency of targeted
drugs. Some of these targeted drugs have demonstrated satisfactory efficacy in the treatment of
advanced NSCLC. These targeted drugs include monoclonal antibodies and tyrosine kinase
inhibitors (TKIs), mostly targeting epidermal growth factor receptors (EGFRs) and vascular
endothelial growth factor (VEGF), such as bevacizumab, cetuximab, gefitinib, erlotinib, and
icotinib. Monoclonal antibodies have become the drugs of choice in various treatment guidelines
due to the good targeting ability, low drug resistance, and good patient tolerability. Bevacizumab
combination chemotherapy is a first-line therapy of NSCLC recommended by the National
Comprehensive Cancer Network (NCCN)7. Additionally, bevacizumab in combination with
paclitaxel/carboplatin has also been approved as the first-line therapy of unresectable advanced,
metastatic, or relapsed non-squamous NSCLC by China Food and Drug Administration (CFDA)
on Jul. 9, 20156.

Compared with traditional chemotherapy that directly inhibit or kill tumor cells, anti-angiogenic
drugs have the following unique advantages8:

The targets are genetically stable vascular endothelial cells (VECs) rather than highly
heterogeneous tumor cells, thus leading to lower drug resistance;

The number of tumor-induced VECs is far less than that of tumor cells, and the efficacy
is preferable targeting on VECs and their cytokines;

Normal VECs are quiescent, whereas tumor VECs are active in proliferation. Anti-
angiogenic therapy targets activated cells and avoids damage to normal VECs, thus
leading to better targeting ability;

Anti-angiogenic therapy can normalize the tumor vessels and thereby reduce the
pressure in tumor tissues. This enhances the delivery of chemotherapeutic agents into
tumor tissues, thus increasing the efficacy of chemotherapy.
Angiogenesis is a basic biological characteristic of tumors. The growth of both solid and
hematologic tumors are depended on angiogenesis regardless of the nature of tumor cells.
Therefore, anti-angiogenic therapy is broad-spectrum and applicable to various tumors.
Bevacizumab is a recombinant humanized monoclonal antibody that selectively binds to human
VEGF and blocks its biological activity. Bevacizumab consists of a framework region of a
human antibody and a humanized murine antigen binding region that can inhibit the binding of
VEGF to its receptors on epithelial cells, Flt-1 and KDR. By blocking the activity of VEGF and
reducing tumor angiogenesis, tumor growth is inhibited9.
In a study conducted by the Estern Cooperative Oncology Group (ECOG), compared with
chemotherapy alone (paclitaxel/ carboplatin), bevacizumab in combination with paclitaxel/carboplatin
significantly increased the overall survival (OS) (median: 12.3 vs. 10.3 months), progression-free
survival (PFS) (median: 6.2 vs. 4.5 months), and overall response rate (ORR) (35% vs. 15%) in
patients with advanced, metastatic, or relapsed non-squamous NSCLC10. In another foreign
AVAiL study, different doses of bevacizumab (7 and 15 mg/kg) in combination with
chemotherapy (cisplatin and gemcitabine) and placebo combine with chemotherapy were
compared for the treatment of non-squamous NSCLC. The study found that the two
bevacizumab groups had significantly increased the PFS (median: 6.7 months (7.5 mg/kg
combination chemotherapy group) vs. 6.5 months (15 mg/kg combination chemotherapy group)
vs. 6.1 months (placebo combination chemotherapy group)) and the ORR (37.8% (7.5 mg/kg
combination chemotherapy group) vs. 34.6% (15 mg/kg combination chemotherapy group) vs.
21.6% (placebo combination chemotherapy group)) in patients with locally advanced, metastatic,
or relapsed non-squamous NSCLC11. In a BEYOND study conducted in China, compared with

placebo in combination with paclitaxel/carboplatin, bevacizumab in combination with
paclitaxel/carboplatin significantly increase the PFS (median: 9.2 vs. 6.5 months), OS (median:
24.3 vs. 17.7 months), and the ORR (54% vs. 26%) in patients with advanced or relapsed non-
squamous NSCLC12.
In China, the antibodies and fusion proteins targeting VEGF are research hotspots. However,
since 2006, the clinical efficacies of various drugs have not been verified and no products have
been marketed. Considering the complexity of macromolecular drugs and the limitations of drug
development capability in China, advanced technologies in antibody development, production,
and quality control is required to develop high-quality VEGF inhibitors that are safe and
effective. IBI305 has showed high similarity to bevacizumab in various pharmaceutical and
nonclinical studies (refer to Investigator's Brochure [IB]). Besides, the efficacy and safety of
bevacizumab for treatment of locally advanced, metastatic or relapsed lung cancer have been
verified. The relevant domestic and external pivotal clinical studies are referable for the protocol
design of IBI305 clinical study. In summary, the clinical study of IBI305 for treatment of
NSCLC has a solid foundation and relatively low risks. The successful development of IBI305
indicates an additional first-line targeted drug for lung cancer in China, providing doctors and
patients with more therapeutic options.
1.1.2 Investigational drug
1.1.2.1 Description of investigational drug
IBI305 is a recombinant humanized anti-VEGF monoclonal antibody injection developed by
Innovent Biologics (Suzhou) Co., Ltd. (hereafter as sponsor) that specifically binds human
VEGF. The molecular weight of IBI305 is 149 KDa. IBI305 specifically binds to VEGF-A,
inhibits the binding of VEGF-A to VEGF-R1 and VEGF-R2, blocks the signaling pathways such
as PI3K/Akt/PKB and Ras-Raf-MEK-ERK. IBI305 also inhibits the growth, proliferation, and
migration of VECs and angiogenesis, decreases the vascular permeability, blocks blood supply to
tumor tissues, inhibits the proliferation and metastasis of tumor cells, and induces the apoptosis
of tumor cells, thereby generates anti-tumor effects. The main active ingredient is recombinant
humanized anti-VEGF monoclonal antibody and excipients include sodium acetate, sorbitol, and
polysorbate 8013. Refer to the Investigator's Brochure for the detailed structure and
physicochemical properties of IBI305.

1.1.2.2 Preclinical studies
Pharmaceutical studies
The pharmaceutical studies showed that stability, primary structure, higher-order structure,
oligosaccharide distribution, charge variant, and product-related impurities of IBI305 are highly
similar to those of bevacizumab, and the process-related impurities meet the proposed
specification. Therefore, IBI305 is considered to have highly similar protein properties and
product quality to bevacizumab13.
Pharmacodynamic studies
In vitro and in vivo pharmacodynamic (PD) studies of IBI305 showed the following findings:
1)
Target: IBI305 displayed specifically high-affinity binding to recombinant human
VEGF-A with an affinity constant same as that of bevacizumab, indicating that IBI305,
the same as bevacizumab, is a specific human VEGF blocker with a clear target.
2)
Specificity: IBI305 displayed specifically high-affinity binding to recombinant human
VEGF-A, medium-affinity binding to canine VEGF-A, but low-affinity binding to
human VEGF-B, VEGF-C, VEGF-D, PlGF, suggesting that IBI305 recognizes specific
targets and has low off-target toxicity risk; no obvious affinity to mouse VEGF-A164
and rat VEGF-A164, suggesting that IBI305 has high species specificity.
3)
Mechanism of action: IBI305 specifically binds to VEGF-A and inhibits the activation
of VEGFR-2 and ERK1/2, blocks the proliferation and migration of HUVEC, and
inhibits the sprouting from rat aortic ring, suggesting that IBI305 antagonizes VEGF-
A-induced signaling pathway to block the proliferation and migration of VECs and
inhibit angiogenesis, which leads to the reduction of nutritional supply and metastasis
of tumor.
4)
Anti-tumor effects: IBI305 significantly inhibits the growth of human colon cancer
Ls174t and lung cancer NCI-H460 cells in xenografts in nude mice, indicating that
IBI305 has significant anti-tumor effects.
Results from in vitro and in vivo studies of IBI305 showed highly similarity with that of
bevacizumab designed simultaneously, demonstrating that the target, mechanism of action,
and anti-tumor effects of IBI305 are highly similar to bevacizumab13.

Pharmacokinetic studies
In vitro and in vivo pharmacokinetic (PK) studies of IBI305 showed the following findings:
1)
IBI305 showed no significant cross-reactivity with normal human tissues and
cynomolgus monkey tissues, and only cross-reacted with the positive-control. i.e.
human angiosarcoma tissue, suggesting that IBI305 is highly specific to cancer tissues
rather than normal human tissues and has very low on-target toxicity.
2)
Linearity: With single dose or repeated doses of IBI305 (2-50 mg/kg) vis intravenous
injection in cynomolgus monkeys, the test showed significant PK, thus reducing the
suddenly rising toxicity risks with increased clinical doses.
3)
Immunogenicity: With single dose or repeated doses of IBI305 or bevacizumab via
intravenous injection in cynomolgus monkeys, the test showed abnormal changes of
drug concentration-time curves in several animals. The anti-drug antibody (ADA) test
results showed that IBI305 has a medium immunogenicity.
4)
Accumulation: With repeated doses of IBI305 or bevacizumab via intravenous
injection in cynomolgus monkeys, the test showed that drug exposure of the last
dose was significantly higher than that of the first dose, and the steady-state drug
concentration after repeated doses was higher than that after a single dose, suggesting
that the drug may be accumulated in body.
The results of tissue cross-reactivity and PK/toxicokinetic studies in cynomolgus monkeys
indicated that IBI305 and bevacizumab have similar characteristics in tissue cross-reactivity and
PK/toxicokinetics13.
Toxicological studies
Toxicological studies of IBI305 showed the following findings:
1)
Single dose: With single dose of IBI305 (up to 300 mg/kg) via intravenous injection in
cynomolgus monkeys, the test showed good tolerability without any abnormal clinical
symptoms and toxicity. The dose was about 48 times the proposed clinical dose for
human based on body surface area. In the safety pharmacology test, with single dose of
IBI305 (50 mg/kg) via intravenous injection in cynomolgus monkeys, the test showed
no significant effects on the central nervous system, respiratory system, and
cardiovascular system, suggesting that the single dose of IBI305 via intravenous
injection has a high safety.

2)
Repeated doses: With repeated doses of IBI305 (up to 50 mg/kg) via intravenous
injection twice weekly for 9 consecutive doses in cynomolgus monkeys, equivalent to
20 times the proposed clinical dose for humans (based on the weight), the test showed
extremely mild to mild linear growth arrest of metaphyseal lines at knee joint and
disordered chondrocyte proliferation, extremely mild increases in macrophage count
in white pulp of spleen, pulmonary (including bronchial) hemorrhage, and deposits of
hemosiderin in lymphoid tissue of bronchial mucosa, indicating that the target organ
toxicities are mainly in the bone, spleen, and lungs.
3)
Immunotoxicity and immunogenicity: With repeated doses of IBI305 via intravenous
injection twice weekly for 9 consecutive doses in cynomolgus monkeys, the test
showed medium immunotoxicity to the spleen. Different doses of IBI305 may result in
the production of ADAs, a portion of which are neutralizing antibodies (NAbs),
indicating that IBI305 has medium immunotoxicity and immunogenicity.
4)
Local irritation test: With repeated dose of IBI305 via intravenous injection in
cynomolgus monkeys, the test showed no irritation at the injection site, suggesting that
administration of IBI305 via intravenous injection is safe and feasible.
5)
In vitro hemolysis assay: With maximum proposed clinical concentration of IBI305
(9 mg/mL), the assay showed no hemolysis, suggesting that IBI305 is suitable for
intravenous injection.
IBI305 has high similarity with bevacizumab in safety pharmacology, long-term toxicity,
immunotoxicity, immunogenicity, local irritation, and hemolysis13.
1.2 Study Principles and Risk/Benefit Assessment
1.2.1 Study principles and dose selection
A biosimilar drug refers to a therapeutic biological product that is similar in quality, safety and
efficacy with an approved reference drug14. IBI305, developed and sold in the market by the
sponsor, is a bevacizumab biosimilar, and has the same administration method and indications
as bevacizumab.

This study is conducted in accordance with the "Guidelines on Development and Evaluation of
Bosimilars (for Trial Version)" issued by the NMPA (formerly CFDA)14. The doses of IBI305
selected in this study are based on the preclinical studies that showed highly similarity between
IBI305 and bevacizumab in pharmacology, PD, PK and toxicology (refer to the Investigator's
Brochure for details). Besides, the efficacy and safety of bevacizumab for treatment of advanced,
metastatic or relapsed non-squamous NSCLC have been verified, and the indications have also
been approved in China. Therefore, the dose and administration of IBI305 is similar to
bevacizumab in this study, that is, 15 mg/kg intravenously on D1 of every 3-week cycle
when used in combination with chemotherapy (paclitaxel and carboplatin). In the subsequent
maintenance monotherapy therapy, IBI305 will be given intravenously at a dose of 7.5 mg/kg on
the first day of every 3-week cycle. This design of this study is to further demonstrate that
IBI305 is similar to bevacizumab in clinical efficacy, safety, and immunogenicity in subjects
with advanced, metastatic or relapsed non-squamous NSCLC.
1.2.2 Risk/benefit assessment
IBI305 is a bevacizumab biosimilar developed by the sponsor. Based on the clinical pharmacology
and toxicology characteristics of IBI305, the risks and benefits of IBI305 are expected to be similar
to bevacizumab.
The treatment-related risks of bevacizumab are detailed in its prescribing information. This study
is the first human study of IBI305 so that unexpected adverse reactions will be possible. The
design of this study ensures the minimized subject risks by close monitoring of the adverse
events (AEs) before, during, and after the infusion of the investigational drugs. Once an adverse
reaction occurs, the investigator will immediately take appropriate action for the subject safety.
The platinum-based therapy is the standard first-line regimen of advanced NSCLC4. This study
uses the combination of paclitaxel/carboplatin, ensuring the basic anti-tumor therapy for subjects.

3 STUDY PLAN
3.1 Overview of Study Design
This is a randomized, double-blind, active-controlled, and multi-center phase III study. A total of
436 subjects across 35 study sites with non-squamous NSCLC will be planned, randomized in a
1:1 ratio into the IBI305 plus paclitaxel/carboplatin group or bevacizumab plus paclitaxel/carboplatin
group, and stratified according to age (< 60 vs. ≥60 years old) and epidermal growth factor
receptor (EGFR) status (wild type vs. unknown type). Each treatment cycle is 3 weeks for both
groups. 15 mg/kg IBI305 or bevacizumab is administered on D1 of each cycle along with
paclitaxel/carboplatin. Subjects will receive up to 6 treatment cycles of combination therapy until
PD, unacceptable toxicity, withdrawal of informed consent, loss of follow-up, or death
(whichever comes first). Then subjects received maintenance monotherapy, that is, discontinuing
paclitaxel/carboplatin while continuing maintenance therapy with IBI305 or bevacizumab. The
maintenance monotherapy continues every 3 weeks. On D1 of each treatment cycle, subjects will
be administered 7.5 mg/kg of either IBI305 or bevacizumab until PD, unacceptable toxicity,
withdrawal of informed consent, lost to follow-up, death, or end of study (whichever comes first).
After discontinuing the study drug, subjects will return to the study site 28 days (± 7 days) after
the last dose for an end-of-treatment visit. If the subjects discontinue the study treatment for
reasons other than PD, subsequent follow-up will be continued until PD, withdrawal of informed
consent, start of other anti-tumor therapies, loss of follow-up, death, or end of study. If the
subjects discontinue the study treatment for PD, the investigator will make telephone follow-up
every 12 weeks (± 7 days) to collect information of subsequent anti-tumor therapies and survival.
A CT or an MRI will be performed every 6 weeks (± 7 days) until PD, withdrawal of informed
consent, start of other anti-tumor therapies, loss of follow-up, death, or end of study. The method
for subsequent imaging examination should be consistent with that at baseline, and the chest,
abdomen and pelvis of the subject must be scanned. Each assessment must be completed within
7 days from the most recent visit. The investigators then perform the evaluation based on the
RECIST v1.1 criteria to determine whether the subject can continue receiving the next cycle of
treatment. Furthermore, the independent tumor evaluation committee (Section 11.1.1) will also
evaluate tumor response according to the RECIST v1.1. If the subjects discontinue the study
treatment for reasons other than PD, subsequent tumor evaluation should be continued according
to the study procedures until PD, withdrawal of informed consent, start of other anti-tumor
therapies, loss of follow-up, death or, end of study.
The study design is shown in Figure 1.

* If the subject is determined by the investigator and the sponsor's doctor to be medically suitable
to continue with the study drugs without any risk or inconvenience, the mistakenly enrolled or
randomized subject will continue with the study treatment and assessments.
In any cases, reasons for withdrawal must be documented in the eCRFs. If the subject withdraws
from the study prematurely for any reason, the investigator should make every effort to persuade
the subject to receive the corresponding assessment, and continue the follow-up of all unresolved
AEs based on the AE reports and follow-up requirements (Table 2):

If the subject withdraws during the study, the series of assessments listed under the End
of Treatment Visit (Section 6.9) should be performed

If the subject withdraws after the end of the treatment visit and has not experienced PD,
the series of assessments listed under the Follow-Up for PD (Section 6.10) should be
performed (tumor assessment is not required to be repeated if it has been performed
within 6 weeks prior to this follow-up)

If the subject withdraws during the follow-up for survival, the information of subsequent
anti-tumor therapies and survival should be collected by telephone follow-up only

5 STUDY TREATMENT
5.1 Therapies by Study Drugs
The study drugs of this study are IBI305 and bevacizumab.
In this study, the dose of IBI305 or bevacizumab during combination therapy with chemotherapy
is 15 mg/kg, while the dose during maintenance monotherapy is 7.5 mg/kg. The study drugs are
administered intravenously on D1 of each 3-week cycle until PD, unacceptable toxicity,
withdrawal of informed consent, loss to follow-up, death, or end of study (whichever comes first).
The duration of the first dose of IBI305 or bevacizumab should be 90 min (± 15 min). If the
first infusion is well-tolerated by the subject, then the duration of the second infusion can be
shortened to 60 min (± 15 min). If the 60 min infusion is also well-tolerated by the subject, then
the subsequent infusions can be completed within 30 min (± 15 min).
5.2 Chemotherapy
Paclitaxel will be administered after the IBI305 or bevacizumab infusion is completed, then
followed by carboplatin:
Paclitaxel: 175 mg/m² administered via intravenous infusion for 3 h (may be adjusted according
to clinical practice of each study site) on D1 of every 3-week cycle for up to 6 cycles until PD,
unacceptable toxicity, withdrawal of informed consent, loss of follow-up, or death.
Carboplatin: AUC 6.0, the infusion time is based on the standard practice of each study site,
administered on D1 of every 3-week cycle for up to 6 cycles until PD, unacceptable toxicity,
withdrawal of informed consent, loss of follow-up, or death.
The chemotherapeutic agents are supplied by the sponsor.
Formulas for calculating surface area, creatinine clearance and carboplatin dose are shown in
Section 13.2.
5.3 Dose Adjustment of Each Study Drug
5.3.1 General principles
The reasons for dose adjustments or delayed administration, measures taken, and
results should be documented in the medical records and eCRFs

If the concomitant symptoms exist at baseline, the investigator will determine whether
the dose should be adjusted according to the change in severity of toxicity. For example,
if the subject has Grade 1 "weakness" at baseline and Grade 2 "weakness" during the
study treatment, the dose should be adjusted based on Grade 1 toxicity since the
severity has increased by one grade
If several toxic reactions of different grades or severity occur simultaneously, the dose
will be adjusted according to the highest observed grade/severity
If a dose adjustment is required solely due to abnormal lab test results, then the dose
should be adjusted based on the measured values obtained prior to the start of the
treatment cycle
If the investigator determines that the toxicity is unlikely to further develop into a
serious or life-threatening event, the current dose will be continued without any
adjustments or treatment interruptions. In addition, dose adjustments or treatment
interruptions will not be performed for non-hemolytic anemia as the symptoms can be
alleviated through blood transfusions.
If the investigator determines that a toxicity is caused by a specific therapeutic drug,
then the dose adjustments of other drugs are not required
Discontinuation of one or two therapeutic drugs before PD will not affect the continued
treatment with other drugs
Dose reductions or adjustments of IBI305 or bevacizumab are not permitted.
Subsequent therapeutic dose will not be adjusted according to weight change, unless
the subject weight has changed by ≥10% from baseline
Once the dose of any chemotherapeutic agents is reduced, the original dose should no
longer be adopted
If any but not all of the therapeutic drug (IBI305, bevacizumab or chemotherapeutic
agents) treatments is interrupted due to toxicity, then this treatment will be considered
as a treatment cycle
If the administration of any one of the chemotherapeutic agents is delayed for more
than 3 weeks, the subject should permanently discontinue that chemotherapeutic agent

5.3.2 Dose adjustments of study drugs
Dose adjustments of IBI305 or bevacizumab are not permitted except for the adjustments
(adjusted to 7.5 mg/kg for maintenance monotherapy) specified in the study protocol. The dose
of IBI305 or bevacizumab is calculated according to the subject weight at baseline (prior to the
first dose), and remains unchanged throughout the study, unless the subject weight has changed
by ≥10% from baseline.
If an infusion reaction occurs during a 60-minute infusion, the infusion time should be extended
to 90 minutes for all subsequent infusions. Likewise, if an infusion reaction occurs during a 30-
minute infusion, the infusion time should be extended to 60 minutes for all subsequent infusions.
IBI305 or bevacizumab in combination with paclitaxel/carboplatin will be administered every
3-week treatment cycle for 6 cycles. If PD is not observed in subject during treatment, then the
subject will continue to receive IBI305 or bevacizumab as maintenance monotherapy every 3-
week treatment cycle until PD, unacceptable toxicity, withdrawal of informed consent, loss of
follow-up, death, or end of study (whichever comes first).
If IBI305 or bevacizumab is permanently discontinued due to unacceptable toxicity or subject
refusal to continue the study drugs during the combination therapy, then the subject will continue
to receive the chemotherapy (paclitaxel/carboplatin) until 6 treatment cycles are completed as
determined by the investigator. If any one of the chemotherapeutic agents (paclitaxel or carboplatin)
is prematurely discontinued due to unacceptable toxicity, the subject can continue to receive
IBI305 or bevacizumab treatment until PD, unacceptable toxicity, withdrawal of informed
consent, loss of follow-up, or death (whichever comes first).
When a Grade 3 or 4 IBI305- or bevacizumab-related toxicity is observed, the investigators
should determine whether to continue or terminate IBI305 or bevacizumab treatment according
to the followings:
First occurrence:
IBI305 or bevacizumab administration should be interrupted until toxicity symptoms return to
baseline level or are at least reduced to the Common Terminology Criteria for Adverse Events
(CTCAE) Grade 1 or lower (except for the special circumstances listed below)
Note that when Grade 4 febrile neutropenia and/or thrombocytopenia occur(s), IBI305
or bevacizumab administration should be interrupted until the symptoms return to
baseline levels or at least reduced to CTCAE Grade 1 or lower, since these events
increase the risk of hemorrhage.

Re-occurrence in re-administration:
If Grade 3 IBI305- or bevacizumab-related toxicity occurs again, the investigator
should assess the risk/benefit of study drug continuation for the subject. If such toxicity
re-occurs again after re-administration, IBI305 or bevacizumab should be permanently
discontinued
If Grade 4 IBI305- or bevacizumab-related toxicity occurs again, IBI305 or
bevacizumab should be permanently discontinued
Measures should be taken in the following special circumstances (classified based on CTCAE
version 4.03):
Hemorrhage
Subjects with Grade 3 or 4 hemorrhages should be treated accordingly and permanently
discontinue the study treatment
Thrombosis/embolism

Subjects with arterial thrombosis of any severity grades should permanently
discontinue the study treatment

Subjects with Grade 4 venous thrombosis should permanently discontinue the
study treatment

Subjects with Grade 3 venous thrombosis should interrupt the study treatment. If
the anticoagulant therapy at the planned therapeutic dose is < 2 weeks, the study
treatment should be interrupted until the anticoagulant therapy is completed. If
the anticoagulant therapy at the planned therapeutic dose is > 2 weeks, IBI305
or bevacizumab administration should be interrupted for 2 weeks, and the study
treatment can be restarted during the anticoagulant therapy if the following criteria
are met:
- INR is within the target range (usually 2-3) prior to restarting of study treatment
- Subjects must not have experienced Grade 3 or 4 hemorrhage since enrollment
- No signs of great vessel invasion or adjacency to great vessels from previous
tumor assessments
Note: Therapeutic dose of anticoagulant therapy is defined as the escalating dose of
warfarin or other anticogulants until INR is maintained at no less than 1.5 (usually

Posterior reversible encephalopathy syndrome (PRES)
There have been a few reports of subjects with signs and symptoms consistent with PRES after
study treatment. This is a rare neurological disease and its signs and symptoms include epilepsy,
headache, altered mental status, visual impairment, or cortical blindness, with or without
hypertension. Subjects with PRES should permanently discontinue the study treatment.
Proteinuria
Urinalysis should be performed prior to each dose of IBI305/bevacizumab unless a 24-hour
urinary protein test has already been done.
First occurrence of proteinuria:
After carrying out the urinalysis, if:
Urine protein is < 2+, continue study treatment as scheduled, no additional tests are
required.
≥2+ (urinalysis): perform 24-hour urinary protein test within 3 days prior to
administration:
•
24-hour urinary protein ≤2 g: continue study treatment as scheduled. and perform
urinalysis dipstick test before each scheduled dose.
•
24-hour urinary protein > 2 g: delay study treatment until 24-hour urinary protein ≤2 g.
and a 24-h urine protein test prior to each subsequent dose is performed until urine protein is
reduced to ≤1 g/24 h. Interrupt study treatment only when 24 h urine protein is > 2 g.
Second and subsequent occurrence of proteinuria:
< 3+ (urinalysis): continue study treatment as scheduled, no additional tests indicated.
≥3+ (urinalysis): perform 24-hour urinary protein test within 3 days prior to
administration:
• 24-hour urinary protein ≤2 g: continue study treatment as scheduled.
• 24-hour urinary protein > 2 g: delay study treatment until 24-hour urinary protein ≤2 g.
and a 24-h urine protein test prior to each subsequent dose is performed until urine protein is
reduced to ≤1 g/24 h. Interrupt study treatment only when 24 h urine protein is > 2 g.

Gastrointestinal perforation
If gastrointestinal perforation occurs, appropriate measures should be taken and the study
treatment should be permanently discontinued.
Wound healing complications
The study treatment should not begin within 28 d after a major surgery, or before the surgical
wound is fully healed. If a complication of wound healing occurs during study treatment, the
study treatment should be interrupted until the wound is fully healed. If an elective surgery is
required, the study treatment should be interrupted.
Abdominal abscess or fistula
If abdominal abscess or fistula occurs, the study treatment should be discontinued. However, the
investigator will determine whether study treatment will be continued if the above AE is resolved.
Infusion-related and allergic reactions:
Infusion-related reactions after first dose of the study drug is uncommon (< 3%), and the incidence
of a severe reaction is only 0.2%.
If a mild (grade 1 or 2) reaction (such as fever, chills, headache, and nausea) occurs, pretreatment
prior to subsequent administration should be performed and infusion time should not be reduced.
If the subject is well-tolerated during infusion after pretreatment, the infusion time can be
reduced by 30 minutes (+10 minutes) for subsequent administration with pretreatment. If an
infusion-related AE occurs during a 60-minute infusion, the subsequent infusion should be
completed within 90 minutes (+15 minutes) with pretreatment. Likewise, if an infusion-related
AE occurs during a 30-minute infusion, the subsequent infusion should be completed in 60 minutes
(+10 minutes) with pretreatment. If a subject has a grade 3 infusion-related reaction, the study
treatment should be interrupted and not be restarted on the same day. However, since there lacks
the dose adjustment method for grade 3 infusion-related reactions, the investigators may decide
to either discontinue the study drug or perform pretreatment, and complete the infusion within
90 minutes (+15 minutes). If an adverse reaction still occurs during a 90-minute infusion, the
infusion should be continued at a slower rate and then gradually returned to a 90-minute infusion.
If the investigator is uncertain about the handling, the study treatment should be discontinued.
When the study treatment is restarted, the subject should be closely monitored based on routine
clinical practice until the possible time of adverse reaction has passed. If a subject has a grade 4
infusion-related reaction, the study treatment should be discontinued.
An allergic reaction is defined as the vascular collapse or shock (systolic BP < 90 mmHg,
unresponsive to rehydration) that occurs within 30 minutes of a study drug infusion caused by

an allergy, with or without respiratory distress. Skin reactions include pruritus, urticaria, and
angioedema. Subjects with allergic reactions should discontinue the study treatment.
5.3.3 Dose adjustments of chemotherapy
Paclitaxel and carboplatin should be administered according to the study site guidelines and local
prescribing information. For the specific information for use, preparation, and storage of
paclitaxel and carboplatin, refer to the prescribing information and local dosing information.
Carboplatin-based chemotherapies have a relatively high incidence of emesis. Therefore,
antiemetics for prophylaxis can be used.
Hematological toxicity:
Absolute neutrophil count (ANC; dose can only be reduced when febrile neutropenia occurs.
ANC must be ≥1.5 × 109/L and platelet count must be ≥100 × 109/L on D1 of each treatment
cycle). Once the chemotherapeutic dose is reduced due to febrile neutropenia or
thrombocytopenia (platelet count < 25 × 109/L or 50 × 109/L with hemorrhage or blood
transfusion required), the original dose should no longer be adopted. If the dose reduction is
required for the third time, the chemotherapy should be immediately discontinued.

Chemotherapy may be delayed for up to 3 weeks. If after the chemotherapy has been delayed for
3 weeks, ANC does not reach ≥1.5 × 109/L and platelet count does not reach ≥100 × 109/L on
D1 of the scheduled chemotherapy, the chemotherapy should be permanently discontinued. If the
above values have been reached, the next course of chemotherapy should be continued.
The investigator should monitor the subject closely for toxicity with particular attention to early
and evident signs of myelosuppression, infection, or febrile neutropenia to timely and
appropriately treat the complications.
Subjects should be informed to pay attention to these signs and receive treatment as soon as possible.
If the chemotherapy must be interrupted due to hematological toxicity, the complete blood count
should be performed regularly (including WBC differentials) until all the counts reach the
minimum requirements for treatment continuation. Thereafter the scheduled treatment plan will
be performed.
Dose adjustments are not required for anemia. However, treatment based on guidelines of each
clinic should be performed.
Gastrointestinal toxicity
Antiemetics will be used to control nausea and/or emesis. If grade 3 or 4 nausea and/or emesis
occur(s) despite of antiemetics, the chemotherapeutic dose should be reduced by 20% for the next
treatment cycle. The dose should be returned to the initial level as possible if the subject is tolerated.
If the subject experiences stomatitis on D1 of any treatment cycle, the chemotherapy should be
interrupted until the symptoms resolve. If the stomatitis has not resolved after 3 weeks, the
chemotherapy should be permanently discontinued (refer to CTCAE version 4.03). If an acute
Grade 3 stomatitis occurs, the chemotherapeutic dose should be reduced to 75% of the proposed
dose when symptoms resolve.
Hepatotoxicity (Paclitaxel)
The paclitaxel dose should be determined based on the lab values measured on D1 of each
treatment cycle.

If paclitaxel is interrupted due to hepatotoxicity, carboplatin should also be interrupted until
paclitaxel is restarted. Paclitaxel will be interrupted for up to 3 weeks. If the subject's hepatic
function does not return to the acceptable ranges in 3 weeks, paclitaxel should be permanently
discontinued. The carboplatin dose will not be adjusted when hepatotoxicity occurs.
The investigators should avoid PD due to abnormal hepatic enzyme levels as possible. If PD
occurs, all the study drugs should be permanently discontinued, including chemotherapy.
Cardiovascular toxicity (paclitaxel)
The arrhythmia in subjects was infrequent in previous clinical studies. However, most subjects
were asymptomatic and electrocardiographic monitoring was not required. Asymptomatic
transient bradycardia was observed in 29% of subjects, but significant atrioventricular block was
rare. Cardiac events should be treated as follows:
Asymptomatic bradycardia: no intervention indicated
Symptomatic arrhythmia during infusion: Discontinue paclitaxel infusion and perform
routine treatment of arrhythmia. Discontinue subsequent paclitaxel treatment.
Document this AE in the AE Report Form of eCRF.
Chest pain and/or symptomatic hypotension (< 90/60 mmHg or rehydration therapy
required): discontinue the paclitaxel infusion. Perform electrocardiography (ECG). If
hypersensitivity reaction is suspected, administer diphenhydramine and dexamethasone
via intravenous infusion. If the chest pain is not considered as cardiogenic, epinephrine
or bronchodilators will be administered. Document this AE in the AE Report Form of
eCRF. Discontinue subsequent paclitaxel treatment and provide symptomatic treatment.
Consult a cardiologist if needed.
Neurotoxicity (paclitaxel)
The dose of paclitaxel should be adjusted according to Table when neuropathy occurs. The dose
adjustment of carboplatin is not needed when neurotoxicity occurs.

Once the dose is reduced due to neurotoxicity, the original dose should no longer be adopted.
If the neurotoxicity does not return to grade 1 after paclitaxel interruption for 3 weeks, paclitaxel
should be permanently discontinued.
Allergic reactions/hypersensitivity reactions (paclitaxel)
Note: Prophylaxis for hypersensitivity reactions (see below) and close monitoring of vital signs
are recommended for subjects with history of mild to moderate hypersensitivity reactions when
hypersensitivity reactions reoccur.
Mild symptoms: complete paclitaxel infusion. Close monitoring; no treatment indicated.
Moderate symptoms: Interrupt paclitaxel infusion, administer diphenhydramine 25–
50 mg and dexamethasone 10 mg via intravenous infusion. Once symptoms have
resolved, resume paclitaxel infusion at a slower rate (20 mL/hour for 15 minutes, then
at 40 mL/hour for 15 minutes, and if no further symptoms develop, continue at original
rate until infusion is complete). Document this AE in the AE Report Form of eCRF. If
symptoms reoccur, interrupt the paclitaxel infusion and permanently discontinue
subsequent paclitaxel infusion.
Severe and life-threatening symptoms: Interrupt paclitaxel infusion, administer
diphenhydramine and dexamethasone via intravenous infusion (as above). Use
epinephrine or bronchodilators if indicated. Document this AE in the AE Report Form
of eCRF. Subsequent courses of paclitaxel infusion should be permanently
discontinued.
Moderate or severe hypersensitivity reactions should be documented as AEs.
Other toxicities
If other unmentioned grade 3–4 toxicities occur, the chemotherapy should be interrupted until
symptoms resolve or return to grade 1. Thereafter restart the infusion at 50% of the original dose
(which should no longer be adopted). If the toxicity does not return to grade 1 after an
interruption for 3 weeks, the chemotherapy should be permanently discontinued. Dose
adjustments are not recommended for grade 1 and 2 toxicities.

5.5 Preparation and Distribution
IBI305 or bevacizumab is diluted in 0.9% sodium chloride solution by the pharmacist or research
nurse before infusion. Check the particles and discoloration prior to administration.
The investigator should ensure that the pharmacist or research nurse administers the study drugs
according to study protocol.
5.6 Packaging, Labeling, and Storage
The sponsor should package and label the study drugs according to appropriate local regulations.
All study drugs (IBI305 and bevacizumab) must be stored at 2–8 °C away from light. The study
drugs should be stored in a safe zone only accessible by authorized staff prior to dispensation to
the subjects.
5.7 Subjects Allocation
After confirming that the subject meets all of the inclusion and exclusion criteria, the study site
will log in the Interactive Web Response System (IWRS) and enter the subject information into
the IWRS. The IWRS will allocate a random number to the subject and provide a medication

5.8 Blinding
This is a randomized, double-blind, and active-controlled study, and only relevant study
personnel had access to the randomization numbers. A non-blinded pharmacist or research nurse
will prepare the medications since IBI305 and bevacizumab do not have an identical appearance.
The pharmacist or research nurse who is responsible for preparing the study drugs is not allowed
to disclose any information regarding treatment allocation to the subject, the subject's family
members, or other personnel including the physician and the relevant study staff.
Unblinding: Subject unblinding should only be performed after database locking.
Emergency unblinding: In case of an emergency where the investigator must know the
medication given to a particular subject, the investigator will unblind the subject via the IWRS
and immediately inform the sponsor and CRO. The reasons for unblinding, date, and outcomes
should be documented in the source document and eCRF of the subject.
5.9 Concomitant Medications and Treatments
All medications except for the study drugs, including other chemotherapies not specified in the
study, Chinese herbal medicines, and other non-traditional therapies, are considered concomitant
medications. All concomitant medications used within 30 days prior to screening should be
documented in the eCRFs, including the information of generic name, route of administration,
start date, end date, and indication.
5.9.1 Prohibited treatment
No other anti-tumor therapies or medications with anti-tumor indications, including Chinese
herbal medicine, radiotherapy, or other investigational drugs, are allowed during this study other
than IBI305, bevacizumab, paclitaxel, and carboplatin.
Severe myelosuppression is possible after chemotherapy. Granulocyte colony-stimulating factor
or granulocyte-macrophage colony-stimulating factor are not allowed to be used prophylactically
in the first treatment cycle.
5.9.2 Permitted treatment
Prophylactic use of anti-emetics, glucocorticoids, or other treatments targeting toxicities is permitted
during the study. Unconventional treatments (such as acupuncture) and vitamins/microelements are
permitted if their use does not affect the study endpoints as determined by the investigators.

Starting from the 2nd chemotherapy cycle, granulocyte colony-stimulating factor or granulocyte-
macrophage colony-stimulating factor are allowed to be used prophylactically to prevent severe
myelosuppression.
Anti-viral therapy was permitted whenever necessary.
Stable doses of anti-epileptic drugs were permitted.
Radiotherapy for bone metastasis was permitted provided that the radiotherapy field did not
include the target lesion
5.9.3 Treatment after study treatment
Subsequent therapy after the end of study treatment should be determined by the subject's
attending doctor.
5.10 Treatment Compliance
Subjects should receive treatment at the study site. The dose and time of administration of
IBI305 or bevacizumab and paclitaxel/carboplatin should be documented in the source records
and eCRFs during each treatment cycle. Reasons for dose adjustments, therapy delay, and
therapy discontinuation should be documented. Treatment compliance is monitored by
medication dispensing and return records, medical records, and eCRFs.
5.11 Drug Return and Destruction
The containers, vials, infusion bags, and syringes of used and partially used drugs can be
destroyed on-site according to the appropriate guidelines and operating procedures established
by study sites and local agencies.
Unless the contents have significant safety issues requiring immediate destruction in accordance
with local regulations, all the unused drugs should be returned and destroyed based on the
requirements of sponsor.
5.12 Study Drug-Related Records
The designated personnel of the study sites should make timely records of receiving, dispensing,
using, storing, returning, and destroying the study drugs in accordance with the relevant
regulations and guidelines.

6.13 Tumor Assessment
Imaging tests (CT or MRI) of the brain, chest, abdomen, and pelvis are required at baseline. If
these tests are performed within 28 days prior to the first dose of the study drug, they do not need
to be repeated unless the investigator believes that there have been changes in the subject's tumor
burden. After the start of treatment, imaging tests are performed once every 6 weeks (±7 days)
and have to be completed within 7 days prior to the scheduled visits, until progressive disease,
start of other treatment, withdrawal of informed consent, loss to follow-up, death, or study
completion. The same method of imaging test was used at baseline and during follow-up.
Imaging evaluations of the chest, abdomen, and pelvis are required.
The investigator should perform a tumor assessment based on RECIST v1.1 (Section 13.3) prior
to each dose to determine whether the subject should continue with the next round of treatment.
An independent review committee will also assess the tumor response (Section 11.1.1). Imaging
tests will not be rescheduled if the study drugs or chemotherapeutic agents are interrupted due to
toxicities. Every effort should be made to continue the schedule for imaging tests even for
subjects who discontinue one or two study treatment(s) due to drug-related toxicities.
If subject experience PD according to the RECIST v1.1 criteria, the attending doctor should
discuss with the subject regarding subsequent routine cancer therapies.
6.14 Clinical Laboratory Evaluations
Clinical laboratory tests will be conducted at the laboratories of each study site. Sample collection
and analysis should be performed according to the requirements of each laboratory.

These tests are carried out at the laboratory of each trial site.
For subsequent visits, all laboratory tests need to be completed within 3 days prior to the
administration. During the study, the frequency of these laboratory tests will be increased if
safety is a concern. The investigator should review the laboratory test results throughout the
study to determine whether the results are clinically significant. The investigator should assess
the changes in laboratory test results. If the investigator considers a laboratory test result to be
abnormal and of clinical significance, it is considered as an AE.
6.15 Vital Signs, Physical Examinations, and Other Safety Assessments

6.15.4 12-Lead ECG
12-lead ECG will be performed during screening. During the study, each medication visit
requires an ECG examination. The following ECG parameters should be documented: HR, PR-
interval, QRS-complex, QT-interval, and QTc-interval. The subject must be in the supine
position for at least 5 minutes prior to undergoing the 12-lead ECG. All ECG are evaluated by
qualified physicians. All clinically significant abnormal findings should be reported as AEs.
6.15.5 Immunogenicity assessment
Immunogenicity tests will be performed in all subjects at 3 blood sampling time points: Within
1 hour prior to the first dose of the study treatment (IBI305/bevacizumab) in C1, within 1 hour
prior to the administration of the study treatment in C4, and during the end-of-treatment visit.
Blood specimens that are positive for anti-drug antibodies (ADA) after dosing will be further
tested for neutralizing antibodies (NAb). Samples were tested at the designated central laboratory.

7 STUDY ASSESSMENTS
7.1 Efficacy Assessment
7.1.1 Primary efficacy endpoint

Objective response rate (ORR)
ORR will be assessed using RECIST v1.1. ORR is defined as the proportion of subjects whose
tumor volume has reduced to a predetermined value, including patients who achieved complete
response (CR) and partial response (PR). The cut-off date for data included in the primary
efficacy evaluation is the 18th week after the last subject is randomized.
7.1.2 Secondary efficacy endpoints

Duration of response (DOR)

Progression-free survival (PFS)

Disease control rate (DCR)

Overall survival (OS)
Each endpoint will be assessed using RECIST v1.1.
DOR is defined as the time from initial tumor response (CR or PR) to PD or death before PD;
Subjects with CR or PR who do not progress or die will be censored on the date of the last tumor
assessment.
PFS is defined as the time from the date of randomization to the date of PD or death; Subjects
who do not progress or die will be censored on the date of the last tumor assessment.
DCR is defined as the proportion of patients whose tumor volume has reduced to a
predetermined value for a minimum time limit, including patients who achieved CR, PR, and SD.
OS is defined as the time from the date of randomization to the date of death of any cause. For
subjects that are alive on the date of study completion or are lost to follow-up, their survival time
will be censored at the date of last contact.

7.2 Safety Assessments
7.2.1 Adverse events
7.2.1.1 Definition
Adverse event
An AE refers to any untoward medical occurrence in a subject after signing the informed consent
form, and does not necessarily have a causal relationship with the treatment. Thus, an AE can be
any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or
disease, whether considered drug related.
Abnormalities resulting from PD are not considered as AEs.
Serious adverse event
A SAE refers to an AE meeting at least one of the followings:
(1) Lead to death, except for deaths caused by PD.
(2) Life-threatening (a "life-threatening event" is defined as an AE when the subject is at
immediate risk of death at the time, but does not include the case that may lead to death
only when the event worsens).
(3) Requires hospitalization or prolonged hospitalization, excluding an emergency or
outpatient visit. Subjects with existing diseases or conditions prior to the enrollment
that do not worsen during the study, and having hospitalization and/or surgery that was
scheduled before the study or during the study do not meet the SAE criterion.
Hospitalizations resulting from PD are not considered as SAEs.
(4) Results in permanent or severe disability/incapacity.
(5) Results in congenital anomalies/birth defects.
(6) Other important medical events: The event that does not result in death, is not life-
threatening or does not require hospitalization, but may jeopardize the health of
subjects and require medical intervention to prevent the SAEs above, is considered as
an SAE
7.2.1.2 Severity of adverse events
The severity of AEs is evaluated using the 5-level criteria of NCI CTCAE v4.03.
For AEs not included in CTCAE v4.03, use the following CTCAE general guidelines:

7.2.1.4 Serious adverse event reporting
SAEs that occur from the signing of informed consent form until 90 days (inclusive) after the last
dose should be reported. The investigator must fill out the "CFDA SAE Report Form", regardless
of whether it is the initial report or a follow-up report, and sign and date the form. The
investigator must report the SAE to the sponsor, CFDA, and ethics committee within 24 hours of
noticing the event. The contact information for reporting is shown in the table below.
For SAEs occurring outside of the above-mentioned period, those considered related to the
investigational drug shall also be reported to the sponsor.
The investigator must submit the completed SAE report form to the sponsor within 24 hours of
noticing the event. The investigator shall urgently perform visit on missing information and
provide a complete SAE report for events that result in death or are life-threatening.
The investigator should also report the event to the CFDA, health administration departments,
and ethics committees in accordance with the regulations.
When submitting the SAE report by email, it is recommended for the investigator to encrypt the
report file and send the report file and password in separate emails.

The investigator is responsible for providing appropriate medical treatment for all AEs (Indicate
the actions taken, such as suspension/termination of the investigational drug, dose modification,
drug therapy, etc.). When an AE occurs, the investigator should actively take appropriate
measures to ensure the safety of the subject. All AEs observed from the signing of the ICF
to the time specified in the protocol (Table 2) must be followed.
The investigator should report any SAE that occurs after the time specified in the protocol (Table 2)
and is suspected of being related to the investigational drug to the sponsor.

7.2.1.7 Pregnancy
Bevacizumab may be harmful to the fetus. Subjects or female partners of male subjects must use
an effective form of contraception during the 6 months after the last dose.
During the study, if a female subject exposed to the study drug becomes pregnant, she must
discontinue study treatment. The investigator must report to the sponsor within 24 hours of
noticing the event and submit the "Innovent clinical Study Pregnancy Report/Follow-Up Form".
During the study, if a female partner of a male subject exposed to the study drugs becomes
pregnant, the subject will continue in the study. The investigator must report to the sponsor
within 24 hours of noticing the event and submit the "Innovent Clinical Study Pregnancy
Report/Follow-Up Form".
The investigator must continuously monitor and visit on the outcome of the pregnancy until 8
weeks after the subject gives birth. The outcome should be reported to the sponsor.
If the outcome of the pregnancy is stillbirth, spontaneous abortion, fetal malformation (any
congenital anomaly/birth defect), or medical abortion, it should be considered as an SAE and the
event is required to be reported in accordance with SAE procedures and time limits.
If the subject also experiences a SAE during the pregnancy, the CFDA SAE Report Form should
also be filled out and reported according to SAE's procedures.
7.2.1.8 Time limits of documenting and reporting AEs
All AEs occurring from the time the subject signs the informed consent form to the time
specified in the protocol (Table 2) (including SAEs and non-SAEs), regardless of their severity,
must be collected and recorded on the AE page of the eCRF.
The investigator must fill out all the required information, including the description of the AE,
start date, end date, severity, measures taken, outcome, seriousness, and causality with the
investigational drug. Each AE should be documented separately.

7.2.1.9 Precautions for AE documentation
Diagnosis, signs, and symptoms
If a diagnosis is already made, the eCRF should record the diagnosis instead of individual
symptoms and signs (such as hepatic failure rather than jaundice, transaminase increased, and
asterixis). However, if the signs and symptoms cannot be attributed to a definitive diagnosis, each
independent event should be documented in the eCRFs as an AE or SAE. Update the report with
visit information if a diagnosis is confirmed later.
AEs secondary to other events
Generally, AEs secondary to other events (such as result of another event or clinical sequelae)
should be documented as the primary event, unless the event is severe or an SAE. However,
clinically significant secondary events should be recorded as independent adverse events in the
eCRFs if they occur at different times than the primary event. If the relationship between events is
unclear, document them as separate events in the eCRFs.
Ongoing or recurrent AEs
An ongoing AE refers to an event that does not resolve and is ongoing between two assessment
time points. These AEs should only be documented once in the eCRFs. The initial severity should
be documented, and the information should be updated if the event exacerbates.
Recurring AEs refer to AE that have resolved between the two time points of assessment but
subsequently occur. These events should be independently documented in the eCRFs.

Abnormalities in laboratory tests/vital signs
All clinically significant laboratory test abnormalities should be reported as AEs. It is the
responsibility of the investigator to review all abnormal laboratory test results, and to make
medical judgments as whether each abnormal laboratory test result should be reported as an AE.
Death
During the entire course of the study, all the deaths that occurred within 90 days after the last dose
were documented in the Death Report Form in the eCRFs, regardless of the causality with the
investigational drug.
When recording a death event, if the cause of death is clear, the cause of death is recorded as an
adverse event with the result of the adverse event being death, and the event is reported as an SAE;
if the cause of the death is unknown at the time of reporting , "Death with Unknown Cause" should
be recorded on the Adverse Event Form of the eCRF and the "Death with Unknown Cause" should
be reported as an SAE first before further investigation is carried out to find the exact cause of
death.
Pre-existing medical conditions
Symptoms/signs presenting during the screening period will be recorded and reported as AEs only
if their severity, frequency, or property becomes aggravated (except for worsening of the studied
disease). The relative change should be documented, such as "increased frequency of headaches".
Hospitalization and prolonged hospitalization, or surgery
Any AE that results in hospitalization or prolonged hospitalization should be documented and
reported as an SAE, except for the following situations:

Hospitalization or prolonged hospitalization as required by study protocol (such as for dose
administration, efficacy evaluation, etc.)

Hospitalization due to a pre-existing medical condition that remains stable, e.g. elective
surgery/therapy scheduled prior to the study.
However, elective surgery/therapy required because of the exacerbated condition during the study
(e.g. surgery/therapy required earlier than scheduled) should be considered as an AE.
The investigator should fill in all required information, including AE terms
(diagnostic terms, or the record of symptoms and signs including laboratory test abnormalities if
there is no diagnosis), start date, end date, severity level, whether it is an AESI, measures taken for
the investigational product, treatment given for the AE, outcome, seriousness, and relationship with
the investigational product. If the signs and symptoms cannot be attributed to a definitive diagnosis,
each AE should be documented independently.

Progressive disease
A progressive disease is defined as the worsening of subject condition caused by the primary tumor
that the investigational drug is targeting, the appearance of new lesions, or the progression of the

8 STATISTICS
8.1 Sample Size Determination
A number of 218 subjects for each group (436 subjects in total) can provide 80% test power to
confirm the clinical equivalence between the treatments of IBI305 in combination with
paclitaxel/carboplatin and bevacizumab in combination with paclitaxel/carboplatin.
The sample size is estimated based on the following assumptions:

The ORRs between IBI305 and bevacizumab group are equivalent

The ORR of subjects in the bevacizumab groups is set to 50.0%

The equivalence margin for the ratio of ORR is taken as (0.75, 1/0.75))

The significance level of the two one-side test is 0.05

1:1 randomization
Based on the above hypotheses, a number of 218 subjects for each group is required (436
subjects in total). The sample size was estimated using PASS 2013.
8.2 Statistical Population
Intention-to-Treat (ITT): All randomized subjects.
Full Analysis Set (FAS): All randomized and evaluable subjects who received at least one dose
of the study treatment. This dataset is used as the primary analysis set for efficacy assessment.
Per-Protocol (PP): Based on the FAS, subjects with the predetermined minimum drug exposure
and without any predetermined major protocol deviations. This dataset is used as the secondary
analysis set for efficacy assessment.
Safety set (SS): Includes all randomized subjects who received at least one dose of the study
treatment and have safety evaluation data. This data set is used for the safety evaluation of this study.

Pharmacodynamic analysis set (PDAS): Includes all subjects in the FAS set with at least one PD
measured value.
8.3 General Principles for Statistical Analyses
For continuous variables, descriptive statistics should include the count, mean, standard
deviation, median, maximum, and minimum. For categorical variables, descriptive statistics will
include the number and percentage of each category. Statistical analyses will be carried out using
SAS 9.4.
8.4 Statistical Methods
8.4.1 Adjustments for covariates
The stratification factors of randomization in this study include age and EGFR status, and the
stratification factors will be considered in the model analysis (GLM or Cox) of primary and
secondary efficacy parameters
8.4.2 Managing dropouts and missing data
The handling of dropout and missing data will be detailed in the statistical analysis plan
8.4.3 Multi-center study
Since this is a multicenter study, the primary endpoint (ORR) will be listed according to study
sites and treatment groups. However, individual equivalence analysis will not be conducted.
Trial sites with fewer than 5 ITT subjects per treatment group will need to be combined for
analysis. Details will be discussed in the data review meeting.
8.4.4 Multiple comparisons and adjustments to multiplicity
The α adjustment for multiple comparisons is not considered.
8.5 Statistical Analyses
8.5.1 Subject distribution
Refer to Figure 1: Study design schematic for the schedule of activities. The number and percentage
of patients who have completed or dropped out of the study (including the reason for dropouts such
as loss to follow-up, AEs, and poor compliance) are summarized based on treatment groups.

The number and percentage of subjects in each analysis set are calculated based on treatment groups.
The number and percentage of protocol deviations are calculated based on treatment groups.
8.5.2 Demographics and other baseline characteristics
Demographic information such as age, height, sex, and weight, and other baseline characteristics
such as disease history (including NSCLC diagnosis, staging, previous cancer treatment, and
target and nontarget lesions) are summarized using descriptive statistics.
8.5.3 Compliance and drug exposure
The required dose and the actual dose must be documented in the eCRF. Subject compliance is
calculated based on the ratio of the actual dose (number of doses) to the required dose (number
of doses). Subject compliance is classified into the following categories: < 80%, 80–120%, and >
120%. The number and percentage of subjects in each category will be summarized.
8.5.4 Efficacy
The efficacy analysis will be based on the FAS. Results of the PP set will also be presented.
8.5.4.1 Primary efficacy endpoint
The primary objective of this study is to determine the clinical equivalence between IBI305 +
paclitaxel/carboplatin and bevacizumab + paclitaxel/carboplatin for the treatment of advanced or relapsed
non-squamous non-small cell lung cancer (NSCLC). The primary endpoint is objective response rate
(ORR). ORR is defined as the incidence of complete response (CR) or partial response (PR), and
a radiological method is used to evaluate target and non-target lesions according to RECIST v1.1.
Subjects without tumor assessments after baseline will be considered as not assessable. Subjects
qualified for the evaluation of CR or PR must have at least one measurable lesion according to RECIST
v1.1. The evaluation of clinical equivalence will be based on the ORR provided by the independent
review committee (IRC). Results provided by the investigator will be used for sensitivity analysis.
Clinical equivalence will be determined by whether the 90% CIs of ORR ratio for subjects in
both IBI305 and bevacizumab groups falls within the equivalence margins of (0.75, 1/0.75).
The ORR and corresponding 95% confidence interval of the two treatment groups, the ORR
difference and the 90% confidence interval, as well as the ORR ratio between the two groups and
the 90% confidence interval will be estimated using the generalized linear model (GLM, which
includes treatment groups and stratification factors).
8.5.4.2 Secondary efficacy endpoints
The secondary endpoints for this study include DOR, DCR, progress-free survival (PFS), and
overall survival (OS).

DCR is defined as the incidence of complete response (CR), partial response (PR) and stable
disease (SD), and a radiological method is used to evaluate target and non-target lesions
according to RECIST v1.1.
DOR is defined as the time from initial tumor response (CR or PR) to PD or death; Subjects with
CR or PR who do not progress or die will be censored on the date of the last tumor assessment.
OS refers to the time from the date of randomization to the date of death (of any cause). For
subjects who are still alive at the time of the analysis, their survival time is censored on the last
known alive date. PFS refers to the time from the date of randomization to the date of first
documented PD or death, whichever occurs first. Subjects who do not progress or die will be
censored on the date of the last tumor assessment. Subjects without tumor assessments after
baseline are censored on their date of randomization.
Median OS and its 95% CI will be estimated using the Kaplan-Meier method. The survival curve
will be plotted. The hazard ratio (HR) between the two groups and its 95% CI will be estimated
using a Cox model. The Cox model includes treatment groups and stratification factors. DOR
and PFS will be analyzed using the same method as for OS. DCR will be analyzed using the
same method for primary efficacy endpoints, but an equivalence test will not be conducted.
8.5.4.3 Sensitivity analysis
The center effect (fixed or random) will be considered in the primary and secondary endpoints
analysis models (GLM or Cox).
8.5.4.4 Antibody and efficacy analysis
Subjects who produce antibodies during the study will be listed. The difference in efficacy
between subjects with and without antibodies will be compared if necessary.
Changes in PK parameters and steady-state trough concentrations of subjects with positive ADA
are analyzed.
8.5.5 Exploratory analysis
Pharmacodynamic parameters: The changes in the serum VEGF level at different time points are
described, and inter-group comparisons are carried out when necessary (based on the PD dataset)
Steady-state trough concentrations of the drug: The level of trough concentration is described
and inter-group comparisons are carried out when necessary (based on the PPK dataset)

9 QUALITY ASSURANCE AND QUALITY CONTROL
According to GCP principles, the sponsor is responsible for implementing and maintaining
quality assurance and quality control systems based on standard operating procedures (SOP),
to ensure that the implementation of the clinical trial and the collection, documentation, and
reporting of trial data is in accordance with the protocol, GCP, and applicable regulatory
requirements.
To ensure that the data is reliable and processed correctly, there should be quality control for
every step during the data processing.
In addition, the Clinical Quality Assurance (CQA) Department of the sponsor and/or CRO may
conduct regular audits of the study process, including but not limited to auditing the study site,
on-site visits, central laboratory, suppliers, clinical database, and the final clinical study report.
Regulatory authorities may also conduct inspections during the trial or at any time after the trial
is completed. The investigator and the research institution must allow the sponsor's representative
and regulatory authorities to review source data.
9.1 Clinical Monitoring
The sponsor has authorized Wuxi Clinical Co., Ltd. to conduct clinical monitoring for this study.
The clinical research associate (CRA) should follow the SOPs of Wuxi Clinical Co., Ltd. when
carrying out monitoring, and has the same rights and responsibilities as the sponsor's monitor.
The CRA should maintain regular communication with the investigator and the sponsor.
Before the start of the study, the associate monitor assess the qualifications of each study site,
and report issues related to facilities, technical equipment, or medical staff to the sponsor. During
the study, the CRA will be responsible for confirming whether written informed consent is
obtained from all subjects, and whether data documentation is accurate and complete. At the
same time, the CRA will compare data entered in to the eCRF with source data, and notify the
investigator of any errors or omissions. The CRA will also verify protocol compliance of the
study site, as well as the dispensing and storage of investigational drugs to ensure protocol
requirements are met.
The monitoring visit will be conducted in accordance with applicable statutes and regulations.
Each site receives regular monitoring visits from the time the subjects are enrolled. The CRA
should submit a written report to the sponsor after each monitoring visit to the study site.

9.2 Data Management/Coding
The Data Management and Biostatistics Department of Wuxi Clinical Co., Ltd will process data
generated from this study in accordance with relevant SOPs.
This study will use an electronic data capture (EDC) system. Trial data will be entered into the
eCRF by the investigator or authorized study personnel. Prior to launching of the study site or
data entry, the investigator and authorized study personnel will receive appropriate training, and
appropriate safety measures will be taken.
All data are input in Chinese. The eCRF should be completed during or soon after each visit, and
should be constantly updated to ensure that it reflects the latest status of the subject. To avoid
discrepancies in outcome assessments between different evaluators, ensure that baseline and all
subsequent efficacy and safety assessments for the same subject are performed by the same
person. The investigator must review trial data to ensure the accuracy and correctness of all data
entered into the eCRF. During the study, the investigator should document any evaluations that
are not conducted, or any information that is not available, applicable, or known. The
investigator needs to sign all verified data electronically.
The CRA will review the eCRF, and evaluate its completeness and consistency. The CRA will
also compare the eCRF with the source documents to ensure the consistency of critical data. Data
entry, corrections, or modifications are completed by the investigator or designated staff. The
CRA do not have access to data entry. The data in eCRF is submitted to the data server, and any
changes to the data will be documented in the audit trail, including the reason for the change, the
name of the operator, as well as the time and date of the change. The roles and permissions of
study personnel responsible for data entry will be predetermined. The CRA or data manager will
submit data queries in the EDC system, and study personnel shall respond to the queries. The
EDC system will record the audit trail of each query, including the name of the investigator, as
well as the time and date.
Unless otherwise specified, the eCRF should be considered simply as a form for data collection
and not a source document. A source file is used by the investigator or hospital, relevant to the
subject, and can prove the existence of the subject, inclusion criteria, and all records of
participation in the study, including laboratory records, ECG results, memorandum, pharmacy
dispensing records, and subject folders.

Confidential
The investigators are required to maintain all source documents and to offer the documents to the
CRA for review during each visit. In addition, the investigator must submit a complete eCRF for
each subject, regardless of the duration of the subject's participation in the study. The study
number and subject number in all supporting documents (such as laboratory records or hospital
records) submitted along with the eCRF should be carefully verified. All personal privacy
information (including the name of the subject) should be deleted or be made indecipherable in
order to protect subject privacy.
The investigator could be automatically added to the eCRF with his/her user ID. The investigators
verify that the record have been reviewed and that the data are accurate with an electronic
signature. The electronic signature is completed with the investigator's user ID and password.
The system automatically attaches the date and time of the signature. The investigator could not
share the user ID and password with other personnel. If data in the eCRF need to be modified,
the procedures defined by the EDC system have to be followed. All modifications and reasons
for the changes are recorded in the audit trail.
Training on the EDC system will be provided to study personnel at the study site.
Adverse events, and concurrent diseases/medical history will be coded. The medical dictionary
used for coding will be described in the Clinical Study Report (CSR).
9.3 Audits and Inspections
The sponsor or its representative (WuXi Clinical Co., Ltd) may conduct quality assurance audits
on the study site, database, and relevant study-related documents. Also, regulatory authorities
may also decide to inspect the study site, database, and relevant study-related documents at its
own discretion. The aim of audits and inspections is to systematically and independently check
all study-related procedures and documents to ensure that the clinical study is being carried out
in accordance with requirements of the trial protocol, GCP, Declaration of Helsinki, and
applicable regulations. The investigator must inform the sponsor immediately when an
inspection notice is received from the regulatory authorities.

10.3 Subject Information and Informed Consent
Prior to undergoing any study procedure, the ICF should be used to explain to potential participants
the potential risks and benefits of this study. The informed consent form should be in a language
that is simple and be easy to understand. The ICF should state that informed consent is voluntary,
emphasize the potential risks and benefits of participating in this study, and that the subject may
withdraw from the study at any time. The investigator may only enroll a subject after fully
explaining the details of the study, answering questions to the subject's satisfaction, giving
the subject sufficient time for consideration, and obtaining written consent from the subject or
his/her legal representative. All signed ICF must be retained in the investigator's documents or
the subject's folder.
The investigator is responsible for explaining the contents of the ICF and obtaining the ICF
signed and dated by the subject or his/her legal representative prior to starting the study. The
investigator should provide the subject with a copy of the signed ICF. The investigator must
document the informed consent process in the source document of the trial.
10.4 Protection of Subject Data
Information about data protection and privacy protection will be included in the ICF (or in some
cases, in a separate document).
Study personnel must ensure that the privacy of clinical trial subjects are protected. In all
documents submitted to the sponsor, the clinical trial subjects must only be identified with
subject number and not with the full name.
Additional precautions should be taken to ensure the confidentiality of the documents and
to prevent the identification of subjects based on genetic data. However, under special
circumstances, some personnel may be permitted to see the genetic data and personal
identification number of a subject. For example, in the event of a medical emergency, the
sponsor, designated physician, or investigator will have access to the subject identification code
and the subject's genetic data. In addition, regulatory agencies may request access to relevant
documents.

MEASURABILITY OF TUMOR AT BASELINE
1.1
Definitions
At baseline, tumor lesions/lymph nodes will be categorized as measurable or not measurable as
follows:
1.1.1
Measurable
Tumor lesions: must be accurately measured in at least one dimension (longest diameter in the
plane of measurement is to be recorded) with a minimum size of:

10 mm by CT scan (CT scan slice thickness no greater than 5 mm)

10 mm caliper measurement by clinical exam (lesions which cannot be accurately
measured with calipers should be documented as not measurable).

20 mm by chest X-ray.
Malignant lymph nodes: To be considered pathologically enlarged and measurable, a lymph
node must be ≥15 mm in short axis when assessed by CT scan (CT scan slice thickness
recommended to be no greater than 5 mm). At baseline and in follow-up, only the short axis will
be measured and followed.
1.1.2
Not measurable
All other lesions, including small lesions (longest diameter <10 mm or pathological lymph nodes
with a short axis ≥10 and <15 mm) as well as truly not measurable lesions. Lesions considered
truly not measurable include: leptomeningeal disease, ascites, pleural or pericardial effusion,
inflammatory breast disease, lymphangitis involving the skin or lungs, abdominal masses/
abdominal organomegaly identified by physical exam but not measurable by reproducible
imaging techniques.
1.1.3
Special considerations regarding measurable bone lesions, cystic lesions, and lesions
with prior locoregional treatment:
Bone lesions:

Bone scan, PET scan or plain films are not considered adequate imaging
techniques to measure bone lesions. However, these techniques can be used to
confirm the presence or disappearance of bone lesions.


Lytic bone lesions or mixed lytic-blastic lesions, with identifiable soft tissue
components, that can be evaluated by cross sectional imaging techniques (such as
CT or MRI) can be considered as measurable lesions if the soft tissue
components meet the definition of measurability described above.

Blastic bone lesions are not measurable.
Cystic lesions:

Lesions that meet the criteria for radiographically defined simple cysts should not
be considered as malignant lesions (neither measurable nor not measurable) since
they are, by definition, simple cysts.

‘Cystic lesions’ thought to represent cystic metastases can be considered as
measurable lesions, if they meet the definition of measurability described above.
However, if noncystic lesions are present in the same patient, these noncystic
lesions are preferred for selection as target lesions.
Lesions with prior locoregional treatment:

Tumor lesions situated in a previously irradiated area or in an area subjected to
other locoregional therapy are usually not considered measurable, unless there
has been demonstrated progression in the lesion. The study protocol should detail
the conditions under which such lesions would be considered measurable.
1.2
Specifications by Methods of Measurements
1.2.1
Measurement of lesions
All measurements should be documented with metric symbols. Calipers should be used if clinical
assessments are required. All baseline evaluations should be performed as close as possible to
the beginning of the treatment but never more than 4 weeks before the beginning of the treatment.
1.2.2
Method of assessment
The same method of assessment and the same technique should be used to characterize each
identified and reported lesion at baseline and during follow-up. Imaging evaluation should
always be done rather than clinical examination unless the lesion(s) being followed cannot be
imaged but are assessable by clinical examination.
Clinical lesions: Clinical lesions will only be considered measurable when they are superficial
and its diameter is ≥10 mm as assessed using calipers (e.g. skin nodules). For skin lesions,
documentation by color photography including a plotting scale to estimate the size of the lesion
is recommended. As noted above, when lesions can be evaluated by both clinical examination
and imaging evaluation, the latter should be undertaken since it is more objective and may also

be reviewed at the end of the study.
Chest X-ray: Chest CT is preferred over chest X-ray, particularly when progression is an
important endpoint, since CT is more sensitive than X-ray, particularly in identifying new lesions.
However, lesions on chest X-ray may be considered measurable if they have clear boundaries
and are surrounded by aerated lung tissues.
CT and MRI: CT is the best currently available and reproducible method to measure lesions
selected for response assessment. This guideline has defined measurability of lesions on CT scan
based on the assumption that CT slice thickness is 5 mm or less. When CT scans have a slice
thickness greater than 5 mm, the minimum size for a measurable lesion should be twice the slice
thickness. MRI is also acceptable in certain situations (e.g. for body scans).
Ultrasound: Ultrasound should not be used for measuring lesion size and should not be used as
a method of measurement. Ultrasound examinations cannot be reproduced in their entirety for
independent review at a later date and, because they are operator dependent, it cannot be
guaranteed that the same technique and measurements will be taken from one assessment to the
next. If new lesions are identified by ultrasound in the course of the study, confirmation by CT
or MRI is recommended. If there is concern about radiation exposure at CT, MRI may be used
instead of CT in selected instances.
Endoscopy and laparoscopy: The utilization of these techniques is not recommended for
objective tumor evaluation. However, they can be used to confirm complete pathological
response when biopsies are obtained or to determine relapse in trials where recurrence following
complete response or surgical resection is an endpoint.
Tumor markers: Tumor markers alone cannot be used to assess objective tumor response. If
markers are initially above the upper limit of normal, however, they must normalize for a patient
to be considered in complete response. Because tumor markers are disease specific, instructions
for their measurement should be incorporated into the protocol on a disease specific basis.
Specific guidelines for both CA-125 response (in recurrent ovarian cancer) and PSA response
(in recurrent prostate cancer) have been published. In addition, the Gynecologic Cancer
Intergroup has developed CA125 progression criteria which are to be integrated with objective
tumor assessment for use in first-line trials in ovarian cancer.
Cytology and histology: These techniques can be used to differentiate between PR and CR in rare
cases if required by the protocol (for example, residual lesions in tumor types such as seminoma,
where known residual benign tumors can remain). When effusions are known to be a potential
adverse effect of treatment (e.g. with certain taxane compounds or angiogenesis inhibitors),
cytological confirmation of the neoplastic origin of any effusion that appears or worsens during

treatment can be considered if the measurable tumor has met criteria for response or stable
disease in order to differentiate between response (or stable disease) and progressive disease.
2.
TUMOR RESPONSE EVALUATION
2.1
Assessment of Overall Tumor Burden and Measurable Disease
To assess objective response or future progression, it is necessary to estimate the overall tumor
burden at baseline and use this as a comparator for subsequent measurements. Only patients with
measurable disease at baseline should be included in regimens where objective tumor response is
the primary endpoint. Measurable disease is defined by the presence of at least one measurable
lesion. In studies where the primary endpoint is tumor progression (either time to progression or
proportion with progression at a fixed date), the protocol must specify if entry is restricted to
those with measurable disease or whether patients having non-measurable disease only are also
eligible.
2.2
Baseline Documentation of "Target" and "Non-Target" Lesions
When more than one measurable lesion is present at baseline, all lesions (five lesions at most,
and two lesions per organ at most) representative of all involved organs should be identified as
target lesions and will be recorded and measured at baseline (This means in instances where
patients have only one or two organ sites involved, a maximum of two and four lesions
respectively will be recorded).
Target lesions should be selected on the basis of their size (lesions with the longest diameter), be
representative of all involved organs, and should be those with reproducible repeated
measurements. It may be the case that, the largest lesion does not have reproducible
measurements, in which circumstance the next largest lesion with reproducible measurements
should be selected.
Lymph nodes merit special mention since their normal anatomical structures may be visible by
imaging even if not involved by tumor. Pathological nodes which are defined as measurable and
may be identified as target lesions must have a short axis of ≥15 mm by CT scan. Only the short
axis of these nodes will contribute to the baseline sum. The short axis of the node is the diameter
normally used by radiologists to judge if a node is invaded by solid tumor. Nodal size is
normally reported as two dimensions in the plane in which the image is obtained (for CT scan
this is almost always the axial plane; for MRI the plane of acquisition may be axial, sagittal or
coronal). The smaller of these measures is the short axis. For example, an abdominal node which
is reported as being 20 mm × 30 mm has a short axis of 20 mm and qualifies as a malignant
measurable node. In this example, 20 mm should be reported as the node measurement. All other
pathological nodes (those with a short axis ≥10 mm but < 15 mm) should be considered non-

target lesions. Lymph nodes that have a short axis < 10 mm are considered non-pathological and
should not be recorded or followed.
A sum of the diameters (longest for non-nodal lesions; short axis for nodal lesions) for all target
lesions will be calculated and reported as the baseline sum of diameters. If lymph nodes are to be
included in the sum, then as noted above, only the short axis is added into the sum. The baseline
sum of diameters will be used as reference to further characterize any objective tumor regression
in the measurable dimension of the disease.
All other lesions (or sites of disease) including pathological lymph nodes should be identified as
non-target lesions and should also be recorded at baseline. Measurements are not required and
these lesions should be recorded as "present", "absent", or in rare cases "unequivocal
progression". In addition, it is possible to record multiple target lesions involving the same organ
as a single item on the case record form (e.g. ‘multiple enlarged pelvic lymph nodes’ or ‘multiple
liver metastases’).
2.3
Response Criteria
2.3.1
Evaluation of target lesions
Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes
(whether target or non-target) must have a reduced short axis of <10 mm.
Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions vs. the
baseline sum of diameters.
Progressive Disease (PD): At least a 20% increase in the sum of diameters of target lesions vs.
the smallest sum during the study (this includes the baseline sum if that is the smallest). In
addition to the relative increase of 20%, the sum must also have an absolute increase of at least
5 mm. (Note: The appearance of one or more new lesions is also considered progression).
Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to
qualify for PD, using the smallest sum of diameters during the study as reference.
2.3.2
Special notes on the assessment of lymph nodes which are target lesions
Lymph nodes identified as target lesions should always have the actual short axis measurement
recorded (measured in the same anatomical plane as during the baseline examination), even if the
nodes regress to below 10 mm at the time of the study. This means that when lymph nodes are
included as target lesions, the "sum" of lesions may not be zero even if complete response
criteria are met, since a normal lymph node is defined as having a short axis of <10 mm. Case
report forms or other data collection methods may therefore be designed to have target nodal
lesions recorded in a separate section where, in order to qualify for CR, each node must have a

short axis of <10 mm. For PR, SD, and PD, the actual short axis measurement of the nodes is to
be included in the sum of target lesions.
Target lesions that are "too small to measure". During the study, all lesions (nodal and non-
nodal) recorded at baseline should have their actual measurements recorded at each subsequent
evaluation, even when very small (e.g. 2 mm). However, sometimes lesions or lymph nodes
which are recorded as target lesions at baseline become so faint on CT scan that the radiologist
may not feel comfortable assigning an exact measurement and may report them as being "too
small to measure". When this occurs it is important that a value be recorded on the case report
form. If it is the opinion of the radiologist that the lesion has probably disappeared, the
measurement should be recorded as 0 mm. If the lesion is believed to be present and is faintly
seen but too small to measure, a default value of 5 mm should be assigned (Note: It is less likely
that this rule will be used for lymph nodes since they usually have a definable size when normal
and are frequently surrounded by fat such as in the retroperitoneum; however, if a lymph node is
believed to be present and is faintly seen but too small to measure, a default value of 5 mm
should be assigned in this circumstance as well). This default value is derived from the 5 mm CT
slice thickness (but should not be changed with varying CT slice thickness). The measurements
of these lesions are potentially non-reproducible, therefore providing this default value will
prevent false responses or progressions caused by measurement errors. To reiterate, however, if
the radiologist is able to provide an actual measurement, that value should be recorded, even if it
is below 5 mm.
Lesions that split or coalesced at the time of treatment. When non-nodal lesions fragment, the
longest diameters of the fragmented portions should be added together to calculate the target lesion sum.
Similarly, as lesions coalesce, a plane between them may be maintained that would aid in obtaining
maximal diameter measurements of each individual lesion. If the lesions have truly coalesced such that
they are no longer separable, the vector of the longest diameter in this instance should be the maximal
longest diameter for the "coalesced lesion".
2.3.3
Evaluation of non-target lesions
This section provides the definitions of the criteria used to determine the tumor response for the
group of non-target lesions. While some non-target lesions may actually be measurable, they do
not need to be measured and instead should be assessed only qualitatively at the time points
specified in the protocol.
Complete Response (CR): Disappearance of all non-target lesions and normalization of tumor
marker level. All lymph nodes must be non-pathological in size (short axis <10 mm).
Non-CR/Non-PD: Persistence of one or more non-target lesion(s) and/or maintenance of tumor
marker level above the normal limits.

Progressive Disease (PD): Unequivocal progression of existing non-target lesions. (Note: The
appearance of one or more new lesions is also considered progression).
2.3.4
Special notes on the assessment of progression of non-target lesions
The concept of progression of non-target disease requires additional explanation as follows: When
the patient also has measurable lesions. In this setting, to achieve ‘unequivocal progression’ on the
basis of the non-target lesion, there must be an overall level of substantial worsening in non-target
disease such that, even in the presence of SD or PR of the target disease, the overall tumor burden
has increased sufficiently to merit discontinuation of therapy. A minimal increase in the size of one
or more non-target lesions is usually not sufficient to quality for unequivocal progression status.
The designation of overall progression solely on the basis of change in non-target lesions in the
face of SD or PR of target disease will therefore be extremely rare.
When the patient has only lesions that are not measurable. This circumstance arises in some
phase III trials when the presence of measurable lesions is not a criterion for study enrollment.
The same general concepts apply here as well. However, in this instance there are no measurable
lesions to factor into the interpretation of an increase in non-measurable lesion burden. Because
worsening in non-target lesion cannot be easily quantified (by definition: if all lesions are truly
not measurable), a useful test that can be applied when assessing patients for unequivocal
progression is to consider if the increase in overall lesion burden based on the change in non-
measurable disease is comparable in magnitude to the increase that would be required to declare
PD for measurable disease: i.e. an increase in tumor burden representing an additional 73%
increase in volume (which is equivalent to a 20% increase of diameter in a measurable lesion).
Examples include an increase in pleural effusion from "trace" to "large amount", an increase in
lymphangitic lesion from localized to widespread, or a description in the protocol such as
"sufficient to require a change in therapy". If ‘unequivocal progression’ is seen, the patient
should be considered to have had overall PD at that point. While it would be ideal to have
objective criteria to apply to diseases that are not measurable, the very nature of these diseases
makes it impossible to do so, therefore the increase must be substantial.
2.3.5
New lesions
The appearance of new malignant lesions denotes disease progression; therefore, some
comments on the detection of new lesions are important. There are no specific criteria for the
identification of new radiographic lesions; however, the finding of a new lesion should be
unequivocal: i.e. not attributable to differences in scanning technique, change in imaging
modality or findings thought to represent something other than tumors (for example, some new
bone lesions which may be simply healed or flare of pre-existing lesions). This is particularly

Confidential
important when the patient’s baseline lesions show partial or complete response. For example,
necrosis of a liver lesion may be reported by a CT scan as a "new" cystic lesion, while it is
actually not.
A lesion identified during a follow-up in an anatomical location that is not discovered during the
baseline scan is considered a new lesion and will indicate disease progression. For example, a
patient with a visceral disease at baseline has a brain CT or MRI which reveals metastases. The
patient's brain metastases are considered evidence of PD even if he/she does not have brain
imaging at baseline.
If a new lesion is equivocal, for example because of its small size, continued therapy and follow-
up evaluation will clarify if it represents a truly new lesion. If repeat scans confirm there is
definitely a new lesion, then progression should be declared using the date of the initial scan.
While FDG-PET response assessments need additional studies, it is sometimes reasonable to
incorporate the use of FDG-PET scanning to complement CT scanning in assessment of
progression (particularly possible "new" lesions). New lesions on the basis of FDG-PET imaging
can be identified as follows:
a.
A negative FDG-PET at baseline and a positive FDG-PET at follow-up is a sign of PD
based on a new lesion.
b.
No FDG-PET at baseline and a positive FDG-PET at follow-up:
If the positive FDG-PET at follow-up corresponds to a new lesion site confirmed by
CT, this is PD. If the positive FDG-PET at follow-up is not confirmed as a new lesion
site on CT, additional follow-up CT scans are needed to determine if there is truly
progression at that site (if so, the date of PD will be the date of the initial abnormal
FDG-PET scan). If the positive FDG-PET at follow-up corresponds to a pre-existing
lesion site on CT that is not progressing according to the anatomic images, this is not PD.
2.4
Evaluation of Best Overall Response
The best overall response is the best response recorded from the start of the study treatment until
the end of treatment, taking into account any requirement for confirmation. On occasion a
response may not be documented until after the end of therapy, so the study protocol should
clearly state if post-treatment assessments are to be considered when determining best overall
response. The study protocol must specify how any new therapy introduced before progression
will affect best response designation. Assignment of best overall response for the patient will
depend on the findings of both target and non-target lesions and will also take into consideration
the appearance of new lesions. Furthermore, depending on the nature of the study and the

Confidential
protocol requirements, confirmatory measurement may also be required. Specifically, in non-
randomized trials where response is the primary endpoint, confirmation of PR or CR is needed to
determine which one is the "best overall response".
2.4.1
Time point response
It is assumed that at each time point specified by the study protocol, a response assessment
occurs. Table 1 on the next page provides a summary of the overall response status calculation at
each time point for patients who have measurable disease at baseline.
When patients have non-measurable (therefore non-target) disease only, Table 2 is to be used.
2.4.2
Missing assessments and non-evaluable targets
When no imaging/measurement is done at a particular time point, the patient is not evaluable
(NE) at that time point. If only a subset of lesion measurements is made at an assessment, usually
the case is also considered NE at that time point, unless a convincing argument can be made that
the missing lesion(s) would not change the response at the assigned time point. This would be
most likely to happen in the case of PD. For example, if a patient has a baseline sum of 50 mm
with three measured lesions and at follow-up only two lesions are assessed and with a sum of 80
mm, the patient will have achieved PD status, regardless of the contribution of the missing lesion.
2.4.3
Best overall response: all time points
The best response is determined once all the data for the patient is obtained.
Best response determination in trials where confirmation of complete or partial response is not
required: Best response in these trials is defined as the best response across all time points (for
example, the best overall response of a patient who has SD at the first assessment, PR at the
second, and PD at the last is PR). When SD is believed to be best response, it must also meet the
minimum time from baseline specified by the protocol. If the minimum time is not met,
otherwise SD is the best time point response, the patient’s best response depends on subsequent
assessments. For example, if a patient has SD at the first assessment, PD at the second and does
not meet the minimum duration for SD, his/her best response is PD. The same patient lost to
follow-up after the first SD assessment would be considered not evaluable.
Best response determination in trials where confirmation of complete or partial response is
required: Complete or partial responses may be claimed only if the criteria for each are met at a
subsequent time point specified in the protocol (generally 4 weeks later). In this circumstance,
the best overall response can be interpreted as in Table 3.

2.4.4
Special notes on response assessment
When nodal lesions are included in the sum of target lesions and the nodes decrease to "normal"
size (<10 mm), they may still have a measurement reported on scans. This measurement should
be recorded even if the nodes are normal in size in order not to overstate progression should it be
based on the increase in size of the nodes. As noted earlier, this means that patients with CR may
not have a total sum of "zero" on the case report form (CRF).
In trials where confirmation of response is required, repeated "NE" time point assessments may
complicate best response determination. The analysis plan for the trial must explain how missing
data/assessments will be addressed in the determination of response and progression. For
example, in most trials it is reasonable to consider a patient with time point responses of PR-NE-
PR as a confirmed response.
Patients with a global deterioration of health status requiring discontinuation of treatment without
objective evidence of disease progression at that time should be reported as "symptomatic
deterioration". Every effort should be made to document objective progression even after
discontinuation of treatment. Symptomatic deterioration is not a descriptor of an objective
response. Instead, it is a reason for stopping the study treatment. The objective response status of
this type of patients is to be determined by evaluation of target and non-target lesions as shown
in Table 1–3.
Conditions that define "early progression, early death, and non-evaluability" are study specific
and should be clearly described in each study protocol (depending on treatment duration and
treatment periodicity).
In some circumstances it may be difficult to distinguish a residual lesion from normal tissues.
When the evaluation of complete response depends upon this determination, it is recommended
that the residual lesion be investigated (by fine needle aspirate/biopsy) before assigning a status
of complete response.
Like a biopsy, FDG-PET may also be used to upgrade a response to a CR in cases where a
residual radiographic abnormality is thought to represent fibrosis or scarring. The use of FDG-
PET in this circumstance should be pre-defined in the protocol and supported by disease specific
medical literature for the indication. However, it must be acknowledged that both approaches
may lead to false positive CR due to limitations of FDG-PET and biopsy resolution/sensitivity.

a "Non-CR/non-PD" is preferred over "stable disease" for non-target disease, since SD is increasingly used as an
endpoint for assessment of efficacy in some trials, thus assigning this category in the absence of measurable
lesions is not advised.
For equivocal findings of progression (e.g. very small and uncertain new lesions; cystic changes
or necrosis in existing lesions), treatment may continue until the next scheduled assessment. If at
the next scheduled assessment, progression is confirmed, the date of progression should be the
earlier date when progression is suspected.

CR = complete response, PR = partial response, SD = stable disease, PD = progressive disease, and NE = not
evaluable.
a If CR is truly achieved at the first time point, then any lesions seen at a subsequent time point, even those meeting
PR criteria relative to baseline, make the disease PD at that time point (since lesions must have reappeared after
CR). Best response would depend on whether the minimum duration for SD is met. However, sometimes CR may
be claimed and subsequent scans suggest small lesions are likely still present, while in fact the patient have PR
instead of CR at the first time point. Under these circumstances, CR should be changed to PR and the best response
is PR.
2.5 Frequency of Tumor Re-Evaluation
Frequency of tumor re-evaluation during treatment should be protocol specific and adapted to the
type and schedule of treatment. However, for phase II studies where the beneficial effect of the
treatment is not known, follow-up every 6–8 weeks (timed to coincide with the end of a cycle) is
reasonable. Smaller or greater time intervals may be justified for certain regimens or circumstances.
The study protocol should specify which organ sites are to be evaluated at baseline (usually those
most likely to be involved with metastatic disease for the tumor type under study) and how
often evaluations are repeated. Normally, all target and non-target sites are evaluated at each
assessment. Under certain circumstances, some non-target organs may be evaluated less frequently.
For example, bone scans may need to be repeated only when complete response is identified in
the target lesion or when progression is suspected.

After the end of the treatment, the need for repeated tumor evaluations depends on whether the
trial has a goal such as a certain response rate or a certain time to an event (progression/death).
If ‘time to an event’ (e.g. time to progression, disease-free survival, progression-free survival) is
the main endpoint of the study, then routine scheduled re-evaluation of lesion sites specified by
the protocol must be carried out. In randomized comparative trials in particular, the scheduled
assessments should be performed on time (for example: every 6–8 weeks during the treatment or
every 3–4 months after the treatment) and should not be affected by treatment delays, holidays or
any other events that might lead to imbalance in the timing of disease assessment between
treatment arms.
2.6 Confirmation of Measurements/Duration of Response
2.6.1 Confirmation
In non-randomized trials where response is the primary endpoint, confirmation of PR and CR is
required to ensure responses identified are not the result of measurement errors. This will also
permit appropriate interpretation of results in the context of historical data. Response
confirmation has been traditionally required in such trials. However, in all other circumstances,
i.e. in randomized trials (phase II or III) or studies where stable disease or progression are the
primary endpoints, confirmation of response is not required since it will not add value to the
interpretation of trial results. However, elimination of the requirement for response confirmation
may increase the importance of central review to protect against bias, in particular in studies
which are not blinded.
In the case of SD, measurements after study entry must have met the minimum interval for SD
(generally not shorter than 6–8 weeks) defined in the study protocol at least once.
2.6.2 Duration of overall response
The duration of overall response is measured from the time CR/PR measurement criteria are first
met CR/PR (whichever is first documented) until the date when recurrent or progressive disease
is objectively documented for the first time (using the shortest time to progressive disease
documented during the study as reference).
The duration of overall complete response is measured from the time CR measurement criteria
are first met until the date when recurrent disease is objectively documented for the first time.
2.6.3 Duration of stable disease
Stable disease is measured from the start of the treatment (in randomized trials, from the date
of randomization) until the criteria for progression are met, using the smallest sum during the
study as reference (if the baseline sum is the smallest, then it is used as the reference for the
calculation of PD).

The clinical relevance of the duration of stable disease varies with different studies and diseases.
If the proportion of patients achieving stable disease for a minimum period of time is an endpoint
of importance in a particular trial, the protocol should specify the minimal time interval required
between two measurements for the determination of stable disease.
Note: The duration of response and stable disease as well as the progression-free survival are
influenced by the frequency of follow-up after baseline evaluation. It is not in the scope of the
guidelines to define a standard follow-up frequency. The frequency should take into account
many parameters including disease types and stages, treatment periodicity, and standard practice.
However, limitations of the precision of the measured endpoint should be taken into account if
comparisons between trials are to be made.

Phase: III
Study Objectives:
Primary Objective:

To compare the objective response rate (ORR) of IBI305 plus paclitaxel/carboplatin versus bevacizumab
plus paclitaxel/carboplatin for the treatment of advanced or relapsed non-squamous non-small cell lung
cancer (NSCLC)
Secondary Objectives:

To compare the duration of response (DOR), progression-free survival (PFS), disease control rate (DCR),
and overall survival (OS) of IBI305 plus paclitaxel/carboplatin versus bevacizumab plus
paclitaxel/carboplatin for the treatment of advanced or relapsed non-squamous NSCLC

To compare the safety and immunogenicity of IBI305 plus paclitaxel/carboplatin versus bevacizumab
plus paclitaxel/carboplatin for the treatment of advanced or relapsed non-squamous NSCLC
Exploratory objectives:

advanced or recurrent non-squamous NSCLC

To compare the PD of IBI305 and bevacizumab in subjects with advanced or recurrent non-squamous
NSCLC
Study design:
This is a randomized, double-blinded, multi-center phase III study. The study planned to enroll and randomize 436
subjects with non-squamous NSCLC in a 1:1 ratio to IBI305 plus paclitaxel/carboplatin group or bevacizumab plus
paclitaxel/carboplatin group. Stratifying factors include age (< 60 vs. ≥60 years old) and EGFR status (wild type vs.
unknown type).
Each treatment cycle is 3 weeks for both groups. 15 mg/kg IBI305 or bevacizumab is administered on D1 of each
cycle along with paclitaxel/carboplatin. Subjects will receive up to 6 treatment cycles of combination therapy until
PD, unacceptable toxicity, withdrawal of informed consent, loss to follow-up, or death (whichever comes first).
Then subjects receive maintenance monotherapy, that is, discontinuing paclitaxel/carboplatin while continuing
therapy with IBI305 or bevacizumab. The maintenance monotherapy continues every 3 weeks. On D1 of each
treatment cycle, subjects will be administered 7.5 mg/kg of either IBI305 or bevacizumab until PD, unacceptable
toxicity, withdrawal of informed consent, loss to follow-up, death, or end of study (whichever comes first).
During the study, a CT or an MRI will be performed every 6 weeks (± 7 days) and be determined whether the study
treatment will be continued by investigators at each site through tumor assessments until PD, withdrawal of informed
consent, lost to follow-up, death, start of other anti-tumor therapies, or end of study. If subjects discontinue the study
treatment for reasons other than PD, tumor assessments will be continued until PD, withdrawal of informed consent, loss
of follow-up, death, start of other anti-tumor therapies, or end of study. If subjects discontinue the study treatment for PD,
the investigators will make telephone follow-up every 12 weeks (± 7 days) to collect information of subsequent anti-tumor
therapies and survival until withdrawal of informed consent, lost to follow-up, death, or end of study.

Statistical methods:
Sample size calculation:
A number of 218 subjects for each group (436 subjects in total) can provide 80% test power to confirm the clinical
equivalence between the treatments of IBI305 in combination with paclitaxel/carboplatin and bevacizumab in
combination with paclitaxel/carboplatin. Estimation parameters for sample size: The significance level of the two-
sided test is 0.05, the ORR of subjects in the IBI305 and bevacizumab groups is about 50.0%, and the equivalence
margin is taken as (-12.5%, 16.7%). Based on the above hypothesis, each group requires 218 subjects (436 subjects
in total).
Efficacy analysis:
Clinical equivalence will be determined by whether the 90% confidence interval (CI) of the difference in ORR
between the IBI305 and bevacizumab arms falls within the preset margin of (-12.5%, 16.7%). The ORR and 95% CI
of two groups, ORR difference and 90% CI, and ORR ratio and 90% CI will be estimated using the generalized
linear model (GLM, including groups and stratification factors).
Median survival (OS) and survival curves will be estimated using the Kaplan-Meier method. The hazard ratio (HR)
and 95% CI of two groups will be estimated using the Cox model. DORs and PFSs will be analyzed by the same
method as the median survivals. DCR will be analyzed using the same method for primary efficacy endpoints, but
an equivalence test will not be conducted.
Safety analysis:
All adverse events (AE) will be coded using MedDRA and graded according to CTCAE v4.03. All treatment-
emergent adverse events (TEAEs), Grade 3 or greater TEAEs, serious adverse events (SAEs), investigational drug-
related TEAEs, investigational drug-related SAEs, TEAEs leading to treatment discontinuation, TEAEs leading
to study termination, and adverse events of special interest (AESIs) will be listed based on system organ class,
preferred terms, and groups and the numbers of corresponding subjects and percentages will be summarized.
In addition, the severity of TEAEs and the correlation with the study drug will also be summarized by system
organ class, preferred terms, and treatment groups.
Measured values and changes from baseline for vital signs, physical examination, laboratory tests and 12-lead ECG
will be analyzed using descriptive statistics. Baseline results and worst results during the study will be presented in
cross tabulation.
The number and percentage of subjects who developed anti-drug antibodies and neutralizing antibodies during the
study will be summarized by treatment group.
PK/PD exploratory analysis:
Mainly based on description, and inter-group comparison will be carried out if necessary

a.
After completing the on-site end-of-treatment visit 28 days after the last dose, subjects who discontinue the
investigational drug treatment due to reasons other than PD should continue to undergo tumor assessments once
every 6 weeks (±7 days) until PD (and begin post-PD follow-up thereafter), withdrawal of consent, start of
another antineoplastic treatment, loss to follow-up, death, or study completion.
b.
For subjects with PD, collect survival information once every 12 weeks (84 days, ±7 days) by phone until death,
loss to follow-up, withdrawal of informed consent, or study completion. Subsequent antineoplastic treatments
should be documented in the eCRF.
c.
Only measure weight.
d.
Clinical laboratory tests are carried out at the laboratory of each hospital. If screening laboratory tests (routine
blood test, blood chemistry, and urinalysis) are performed within 7 days prior to the first dose, the screening
results may be used as baseline data. For subsequent visits, all laboratory tests have to be completed within 3
days prior to the dose administration.
e.
A urinalysis is required before each IBI305/bevacizumab infusion to test urine protein.
f.
Women of childbearing age should undergo a serum/urine pregnancy test.
g.
Immunogenicity tests will be performed in all subjects at 3 blood sampling time points: Within 1 hour prior to
the first dose of the study treatment (IBI305/bevacizumab) in C1, within 1 hour prior to the administration of
the study treatment in C4, and during the end-of-treatment visit. Blood specimens that are positive for anti-drug
antibodies (ADA) after dosing will be further tested for neutralizing antibodies (NAb). Samples will be tested
at the designated central laboratory.
h.
Image assessments (CT or MRI) of the brain, chest, abdomen, and pelvis should be completed at baseline. If
these tests are performed within 28 days prior to the first dose of the study drug, they do not need to be repeated
unless the investigator believes that there have been changes in the subject's tumor burden. After the start of
treatment, imaging tests are performed once every 6 weeks (±7 days) and have to be completed within 7 days
prior to the scheduled visits, until progressive disease, start of other treatment, withdrawal of informed consent,
loss to follow-up, death, or study completion. The same method of imaging test is used at baseline and during
follow-up. Imaging evaluations of the chest, abdomen, and pelvis are required.
i.
All subjects should undergo tumor tissue EGFR testing.

j.
Each treatment cycle of the investigational product contains 3 weeks. The dose of IBI305 or bevacizumab is 15
mg/kg when used in combination with chemotherapeutic drugs and 7.5 mg/kg in the maintenance monotherapy,
given on D1 of every treatment cycle until progressive disease (PD), unacceptable toxic reactions, withdrawal
of informed consent, loss to follow-up, death, or end of study, whichever occurs first. After all assessments
were completed, the study drug was administered followed by chemotherapy. The first dose of study drug was
completed within 24 h after randomization.
k.
Each treatment cycle is 3 weeks long. Chemotherapy (paclitaxel + carboplatin) is administered on D1 of each
cycle for up to 6 cycles, or until disease progression (PD), unacceptable toxicity, withdrawal of informed
consent, loss to follow-up, or death. Paclitaxel is administered after the infusion of study drug is completed,
followed by carboplatin.

1 INTRODUCTION
1.1 Study Background
1.1.1 Disease background
Lung cancer has the highest incidence and mortality globally among all cancers. According to
the 2012 Global Cancer Statistics (GLOBOCAN 2012) published by International Agency for
Research on Cancer, there were approximately 1.8 million new lung cancer cases worldwide,
which accounted for 13% of the global newly-diagnosed cancers, and 58% of these cases
occurred in underdeveloped areas1. According to the data released by the National Central
Cancer Registry of China in 2015, lung cancer was the most prevalent malignancy in China in
2011, with about 650,000 new cases every year. Lung cancer was also the leading cause of death,
with about 520,000 deaths per year2. The limited clinical treatment of lung cancer is the main
reason for its poor prognosis. There is a huge demand for new types of lung cancer treatment
drugs.
Approximately 85–90% of lung cancers are non-small cell lung cancer (NSCLC) and patients
with NSCLC are usually in the advanced stages when diagnosed3. According to the Chinese
guidelines for the diagnosis and treatment of primary lung cancer, anatomic pulmonary resection
is the mainstay of treatment for early stage lung cancers4. However, despite surgery, some
patients develop distance metastases that eventually lead to death5. Surgery is not possible for
most patients with clearly diagnosed stage IIIB and IV as well as some patients with stage IIIA
NSCLC4. Comprehensive treatment based on systemic therapy is used to maximize patient
survival, control progressive disease, and improve the quality of life6.
In recent years, anti-tumor therapies have entered a new era with the emergency of targeted
drugs. Some of these targeted drugs have demonstrated satisfactory efficacy in the treatment of
advanced NSCLC. These targeted drugs include monoclonal antibodies and tyrosine kinase
inhibitors (TKIs), mostly targeting epidermal growth factor receptors (EGFRs) and vascular
endothelial growth factor (VEGF), such as bevacizumab, cetuximab, gefitinib, erlotinib, and
icotinib. Monoclonal antibodies have become the drugs of choice in various treatment guidelines
due to the good targeting ability, low drug resistance, and good patient tolerability. Bevacizumab
combination chemotherapy is a first-line therapy of NSCLC recommended by the National
Comprehensive Cancer Network (NCCN)7. Additionally, bevacizumab in combination with
paclitaxel/carboplatin has also been approved as the first-line therapy of unresectable advanced,
metastatic, or relapsed non-squamous NSCLC by China Food and Drug Administration (CFDA)
on Jul. 9, 20156.

Compared with traditional chemotherapy that directly inhibit or kill tumor cells, anti-angiogenic
drugs have the following unique advantages8:

The targets are genetically stable vascular endothelial cells (VECs) rather than highly
heterogeneous tumor cells, thus leading to lower drug resistance;

The number of tumor-induced VECs is far less than that of tumor cells, and the efficacy
is preferable targeting on VECs and their cytokines;

Normal VECs are quiescent, whereas tumor VECs are active in proliferation. Anti-
angiogenic therapy targets activated cells and avoids damage to normal VECs, thus
leading to better targeting ability;

Anti-angiogenic therapy can normalize the tumor vessels and thereby reduce the
pressure in tumor tissues. This enhances the delivery of chemotherapeutic agents into
tumor tissues, thus increasing the efficacy of chemotherapy.
Angiogenesis is a basic biological characteristic of tumors. The growth of both solid and
hematologic tumors are depended on angiogenesis regardless of the nature of tumor cells.
Therefore, anti-angiogenic therapy is broad-spectrum and applicable to various tumors.
Bevacizumab is a recombinant humanized monoclonal antibody that selectively binds to human
VEGF and blocks its biological activity. Bevacizumab consists of a framework region of a
human antibody and a humanized murine antigen binding region that can inhibit the binding of
VEGF to its receptors on epithelial cells, Flt-1 and KDR. By blocking the activity of VEGF and
reducing tumor angiogenesis, tumor growth is inhibited9.
In a study conducted by the Estern Cooperative Oncology Group (ECOG), compared with
chemotherapy alone (paclitaxel/ carboplatin), bevacizumab in combination with paclitaxel/carboplatin
significantly increased the overall survival (OS) (median: 12.3 vs. 10.3 months), progression-free
survival (PFS) (median: 6.2 vs. 4.5 months), and overall response rate (ORR) (35% vs. 15%) in
patients with advanced, metastatic, or relapsed non-squamous NSCLC10. In another foreign
AVAiL study, different doses of bevacizumab (7 and 15 mg/kg) in combination with
chemotherapy (cisplatin and gemcitabine) and placebo combine with chemotherapy were
compared for the treatment of non-squamous NSCLC. The study found that the two
bevacizumab groups had significantly increased the PFS (median: 6.7 months (7.5 mg/kg
combination chemotherapy group) vs. 6.5 months (15 mg/kg combination chemotherapy group)
vs. 6.1 months (placebo combination chemotherapy group)) and the ORR (37.8% (7.5 mg/kg
combination chemotherapy group) vs. 34.6% (15 mg/kg combination chemotherapy group) vs.
21.6% (placebo combination chemotherapy group)) in patients with locally advanced, metastatic,
or relapsed non-squamous NSCLC11. In a BEYOND study conducted in China, compared with

placebo in combination with paclitaxel/carboplatin, bevacizumab in combination with
paclitaxel/carboplatin significantly increase the PFS (median: 9.2 vs. 6.5 months), OS (median:
24.3 vs. 17.7 months), and the ORR (54% vs. 26%) in patients with advanced or relapsed non-
squamous NSCLC12.
In China, the antibodies and fusion proteins targeting VEGF are research hotspots. However,
since 2006, the clinical efficacies of various drugs have not been verified and no products have
been marketed. Considering the complexity of macromolecular drugs and the limitations of drug
development capability in China, advanced technologies in antibody development, production,
and quality control is required to develop high-quality VEGF inhibitors that are safe and
effective. IBI305 has showed high similarity to bevacizumab in various pharmaceutical and
nonclinical studies (refer to Investigator's Brochure [IB]). Besides, the efficacy and safety of
bevacizumab for treatment of locally advanced, metastatic or relapsed lung cancer have been
verified. The relevant domestic and external pivotal clinical studies are referable for the protocol
design of IBI305 clinical study. In summary, the clinical study of IBI305 for treatment of
NSCLC has a solid foundation and relatively low risks. The successful development of IBI305
indicates an additional first-line targeted drug for lung cancer in China, providing doctors and
patients with more therapeutic options.
1.1.2 Investigational drug
1.1.2.1 Description of investigational drug
IBI305 is a recombinant humanized anti-VEGF monoclonal antibody injection developed by
Innovent Biologics (Suzhou) Co., Ltd. (hereafter as sponsor) that specifically binds human
VEGF. The molecular weight of IBI305 is 149 KDa. IBI305 specifically binds to VEGF-A,
inhibits the binding of VEGF-A to VEGF-R1 and VEGF-R2, blocks the signaling pathways such
as PI3K/Akt/PKB and Ras-Raf-MEK-ERK. IBI305 also inhibits the growth, proliferation, and
migration of VECs and angiogenesis, decreases the vascular permeability, blocks blood supply to
tumor tissues, inhibits the proliferation and metastasis of tumor cells, and induces the apoptosis
of tumor cells, thereby generates anti-tumor effects. The main active ingredient is recombinant
humanized anti-VEGF monoclonal antibody and excipients include sodium acetate, sorbitol, and
polysorbate 8013. Refer to the Investigator's Brochure for the detailed structure and
physicochemical properties of IBI305.

1.1.2.2 Preclinical studies
Pharmaceutical studies
The pharmaceutical studies showed that stability, primary structure, higher-order structure,
oligosaccharide distribution, charge variant, and product-related impurities of IBI305 are highly
similar to those of bevacizumab, and the process-related impurities meet the proposed
specification. Therefore, IBI305 is considered to have highly similar protein properties and
product quality to bevacizumab13.
Pharmacodynamic studies
In vitro and in vivo pharmacodynamic (PD) studies of IBI305 showed the following findings:
1)
Target: IBI305 displayed specifically high-affinity binding to recombinant human
VEGF-A with an affinity constant same as that of bevacizumab, indicating that IBI305,
the same as bevacizumab, is a specific human VEGF blocker with a clear target.
2)
Specificity: IBI305 displayed specifically high-affinity binding to recombinant human
VEGF-A, medium-affinity binding to canine VEGF-A, but low-affinity binding to
human VEGF-B, VEGF-C, VEGF-D, PlGF, suggesting that IBI305 recognizes specific
targets and has low off-target toxicity risk; no obvious affinity to mouse VEGF-A164
and rat VEGF-A164, suggesting that IBI305 has high species specificity.
3)
Mechanism of action: IBI305 specifically binds to VEGF-A and inhibits the activation
of VEGFR-2 and ERK1/2, blocks the proliferation and migration of HUVEC, and
inhibits the sprouting from rat aortic ring, suggesting that IBI305 antagonizes VEGF-
A-induced signaling pathway to block the proliferation and migration of VECs and
inhibit angiogenesis, which leads to the reduction of nutritional supply and metastasis
of tumor.
4)
Anti-tumor effects: IBI305 significantly inhibits the growth of human colon cancer
Ls174t and lung cancer NCI-H460 cells in xenografts in nude mice, indicating that
IBI305 has significant anti-tumor effects.
Results from in vitro and in vivo studies of IBI305 showed highly similarity with that of
bevacizumab designed simultaneously, demonstrating that the target, mechanism of action,
and anti-tumor effects of IBI305 are highly similar to bevacizumab13.

Pharmacokinetic studies
In vitro and in vivo pharmacokinetic (PK) studies of IBI305 showed the following findings:
1)
IBI305 showed no significant cross-reactivity with normal human tissues and
cynomolgus monkey tissues, and only cross-reacted with the positive-control. i.e.
human angiosarcoma tissue, suggesting that IBI305 is highly specific to cancer tissues
rather than normal human tissues and has very low on-target toxicity.
2)
Linearity: With single dose or repeated doses of IBI305 (2-50 mg/kg) vis intravenous
injection in cynomolgus monkeys, the test showed significant PK, thus reducing the
suddenly rising toxicity risks with increased clinical doses.
3)
Immunogenicity: With single dose or repeated doses of IBI305 or bevacizumab via
intravenous injection in cynomolgus monkeys, the test showed abnormal changes of
drug concentration-time curves in several animals. The anti-drug antibody (ADA) test
results showed that IBI305 has a medium immunogenicity.
4)
Accumulation: With repeated doses of IBI305 or bevacizumab via intravenous
injection in cynomolgus monkeys, the test showed that drug exposure of the last
dose was significantly higher than that of the first dose, and the steady-state drug
concentration after repeated doses was higher than that after a single dose, suggesting
that the drug may be accumulated in body.
The results of tissue cross-reactivity and PK/toxicokinetic studies in cynomolgus monkeys
indicated that IBI305 and bevacizumab have similar characteristics in tissue cross-reactivity and
PK/toxicokinetics13.
Toxicological studies
Toxicological studies of IBI305 showed the following findings:
1)
Single dose: With single dose of IBI305 (up to 300 mg/kg) via intravenous injection in
cynomolgus monkeys, the test showed good tolerability without any abnormal clinical
symptoms and toxicity. The dose was about 48 times the proposed clinical dose for
human based on body surface area. In the safety pharmacology test, with single dose of
IBI305 (50 mg/kg) via intravenous injection in cynomolgus monkeys, the test showed
no significant effects on the central nervous system, respiratory system, and
cardiovascular system, suggesting that the single dose of IBI305 via intravenous
injection has a high safety.

2)
Repeated doses: With repeated doses of IBI305 (up to 50 mg/kg) via intravenous
injection twice weekly for 9 consecutive doses in cynomolgus monkeys, equivalent to
20 times the proposed clinical dose for humans (based on the weight), the test showed
extremely mild to mild linear growth arrest of metaphyseal lines at knee joint and
disordered chondrocyte proliferation, extremely mild increases in macrophage count
in white pulp of spleen, pulmonary (including bronchial) hemorrhage, and deposits of
hemosiderin in lymphoid tissue of bronchial mucosa, indicating that the target organ
toxicities are mainly in the bone, spleen, and lungs.
3)
Immunotoxicity and immunogenicity: With repeated doses of IBI305 via intravenous
injection twice weekly for 9 consecutive doses in cynomolgus monkeys, the test
showed medium immunotoxicity to the spleen. Different doses of IBI305 may result in
the production of ADAs, a portion of which are neutralizing antibodies (NAbs),
indicating that IBI305 has medium immunotoxicity and immunogenicity.
4)
Local irritation test: With repeated dose of IBI305 via intravenous injection in
cynomolgus monkeys, the test showed no irritation at the injection site, suggesting that
administration of IBI305 via intravenous injection is safe and feasible.
5)
In vitro hemolysis assay: With maximum proposed clinical concentration of IBI305
(9 mg/mL), the assay showed no hemolysis, suggesting that IBI305 is suitable for
intravenous injection.
IBI305 has high similarity with bevacizumab in safety pharmacology, long-term toxicity,
immunotoxicity, immunogenicity, local irritation, and hemolysis13.
1.2 Study Principles and Risk/Benefit Assessment
1.2.1 Study principles and dose selection
A biosimilar drug refers to a therapeutic biological product that is similar in quality, safety and
efficacy with an approved reference drug14. IBI305, developed and sold in the market by the
sponsor, is a bevacizumab biosimilar, and has the same administration method and indications
as bevacizumab.

Confidential
This study is conducted in accordance with the "Guidelines on Development and Evaluation of
Bosimilars (for Trial Version)" issued by the NMPA (formerly CFDA)14. The doses of IBI305
selected in this study are based on the preclinical studies that showed highly similarity between
IBI305 and bevacizumab in pharmacology, PD, PK and toxicology (refer to the Investigator's
Brochure for details). Besides, the efficacy and safety of bevacizumab for treatment of advanced,
metastatic or relapsed non-squamous NSCLC have been verified, and the indications have also
been approved in China. Therefore, the dose and administration of IBI305 is similar to
bevacizumab in this study, that is, 15 mg/kg intravenously on D1 of every 3-week cycle
when used in combination with chemotherapy (paclitaxel and carboplatin). In the subsequent
maintenance monotherapy therapy, IBI305 will be given intravenously at a dose of 7.5 mg/kg on
the first day of every 3-week cycle. This design of this study is to further demonstrate that
IBI305 is similar to bevacizumab in clinical efficacy, safety, and immunogenicity in subjects
with advanced, metastatic or relapsed non-squamous NSCLC.
1.2.2 Risk/benefit assessment
IBI305 is a bevacizumab biosimilar developed by the sponsor. Based on the clinical pharmacology
and toxicology characteristics of IBI305, the risks and benefits of IBI305 are expected to be similar
to bevacizumab.
The treatment-related risks of bevacizumab are detailed in its prescribing information. This study
is the first human study of IBI305 so that unexpected adverse reactions will be possible. The
design of this study ensures the minimized subject risks by close monitoring of the adverse
events (AEs) before, during, and after the infusion of the investigational drugs. Once an adverse
reaction occurs, the investigator will immediately take appropriate action for the subject safety.
The platinum-based therapy is the standard first-line regimen of advanced NSCLC4. This study
uses the combination of paclitaxel/carboplatin, ensuring the basic anti-tumor therapy for subjects.

3 STUDY PLAN
3.1 Overview of Study Design
This is a randomized, double-blind, active-controlled, and multi-center phase III study. A total of
436 subjects across 35 study sites with non-squamous NSCLC will be planned, randomized in a
1:1 ratio into the IBI305 plus paclitaxel/carboplatin group or bevacizumab plus paclitaxel/carboplatin
group, and stratified according to age (< 60 vs. ≥60 years old) and epidermal growth factor
receptor (EGFR) status (wild type vs. unknown type). Each treatment cycle is 3 weeks for both
groups. 15 mg/kg IBI305 or bevacizumab is administered on D1 of each cycle along with
paclitaxel/carboplatin. Subjects will receive up to 6 treatment cycles of combination therapy until
PD, unacceptable toxicity, withdrawal of informed consent, loss of follow-up, or death
(whichever comes first). Then subjects received maintenance monotherapy, that is, discontinuing
paclitaxel/carboplatin while continuing maintenance therapy with IBI305 or bevacizumab. The
maintenance monotherapy continues every 3 weeks. On D1 of each treatment cycle, subjects will
be administered 7.5 mg/kg of either IBI305 or bevacizumab until PD, unacceptable toxicity,
withdrawal of informed consent, lost to follow-up, death, or end of study (whichever comes first).
After discontinuing the study drug, subjects will return to the study site 28 days (± 7 days) after
the last dose for an end-of-treatment visit. If the subjects discontinue the study treatment for
reasons other than PD, subsequent follow-up will be continued until PD, withdrawal of informed
consent, start of other anti-tumor therapies, loss of follow-up, death, or end of study. If the
subjects discontinue the study treatment for PD, the investigator will make telephone follow-up
every 12 weeks (± 7 days) to collect information of subsequent anti-tumor therapies and survival.
A CT or an MRI will be performed every 6 weeks (± 7 days) until PD, withdrawal of informed
consent, start of other anti-tumor therapies, loss of follow-up, death, or end of study. The method
for subsequent imaging examination should be consistent with that at baseline, and the chest,
abdomen and pelvis of the subject must be scanned. Each assessment must be completed within
7 days from the most recent visit. The investigators then perform the evaluation based on the
RECIST v1.1 criteria to determine whether the subject can continue receiving the next cycle of
treatment. Furthermore, the independent tumor evaluation committee (Section 11.1.1) will also
evaluate tumor response according to the RECIST v1.1. If the subjects discontinue the study
treatment for reasons other than PD, subsequent tumor evaluation should be continued according
to the study procedures until PD, withdrawal of informed consent, start of other anti-tumor
therapies, loss of follow-up, death or, end of study.
The study design is shown in Figure 1.

measures should be taken. In addition, the sponsor or personnel designated by the
sponsor should be notified.

Withdrawal of informed consent form by the subject

Serious protocol deviation determined by the investigator and/or sponsor

Poor protocol compliance

Study termination by the investigator or sponsor for any reason

Enrollment error* (enrollment of subjects who have violated the inclusion/exclusion
criteria)

Use of prohibited concomitant medications or other medications that the investigator
believes that it may result in toxicities or may affect study results

Subject lost to follow-up

Death of subject
* If the subject is determined by the investigator and the sponsor's doctor to be medically suitable
to continue with the study drugs without any risk or inconvenience, the mistakenly enrolled or
randomized subject will continue with the study treatment and assessments.
In any cases, reasons for withdrawal must be documented in the eCRFs. If the subject withdraws
from the study prematurely for any reason, the investigator should make every effort to persuade
the subject to receive the corresponding assessment, and continue the follow-up of all unresolved
AEs based on the AE reports and follow-up requirements (Table 2):

If the subject withdraws during the study, the series of assessments listed under the End
of Treatment Visit (Section 6.9) should be performed

If the subject withdraws after the end of the treatment visit and has not experienced PD,
the series of assessments listed under the Follow-Up for PD (Section 6.10) should be
performed (tumor assessment is not required to be repeated if it has been performed
within 6 weeks prior to this follow-up)

If the subject withdraws during the follow-up for survival, the information of subsequent
anti-tumor therapies and survival should be collected by telephone follow-up only
Subjects who withdraw their informed consent are not to be contacted again unless they clearly
indicate the willingness to be contacted. The sponsor may use the clinical study data obtained
before the withdrawal of informed consent.
Subjects who have been randomized will not be replaced.

5 STUDY TREATMENT
5.1 Therapies by Study Drugs
The study drugs of this study are IBI305 and bevacizumab.
In this study, the dose of IBI305 or bevacizumab during combination therapy with chemotherapy
is 15 mg/kg, while the dose during maintenance monotherapy is 7.5 mg/kg. The study drugs are
administered intravenously on D1 of each 3-week cycle until PD, unacceptable toxicity,
withdrawal of informed consent, loss to follow-up, death, or end of study (whichever comes first).
The duration of the first dose of IBI305 or bevacizumab should be 90 min (± 15 min). If the
first infusion is well-tolerated by the subject, then the duration of the second infusion can be
shortened to 60 min (± 15 min). If the 60 min infusion is also well-tolerated by the subject, then
the subsequent infusions can be completed within 30 min (± 15 min).
5.2 Chemotherapy
Paclitaxel will be administered after the IBI305 or bevacizumab infusion is completed, then
followed by carboplatin:
Paclitaxel: 175 mg/m² administered via intravenous infusion for 3 h (may be adjusted according
to clinical practice of each study site) on D1 of every 3-week cycle for up to 6 cycles until PD,
unacceptable toxicity, withdrawal of informed consent, loss of follow-up, or death.
Carboplatin: AUC 6.0, the infusion time is based on the standard practice of each study site,
administered on D1 of every 3-week cycle for up to 6 cycles until PD, unacceptable toxicity,
withdrawal of informed consent, loss of follow-up, or death.
The chemotherapeutic agents are supplied by the sponsor.
Formulas for calculating surface area, creatinine clearance and carboplatin dose are shown in
Section 13.2.
5.3 Dose Adjustment of Each Study Drug
5.3.1 General principles
The reasons for dose adjustments or delayed administration, measures taken, and
results should be documented in the medical records and eCRFs

Confidential
If the concomitant symptoms exist at baseline, the investigator will determine whether
the dose should be adjusted according to the change in severity of toxicity. For example,
if the subject has Grade 1 "weakness" at baseline and Grade 2 "weakness" during the
study treatment, the dose should be adjusted based on Grade 1 toxicity since the
severity has increased by one grade
If several toxic reactions of different grades or severity occur simultaneously, the dose
will be adjusted according to the highest observed grade/severity
If a dose adjustment is required solely due to abnormal lab test results, then the dose
should be adjusted based on the measured values obtained prior to the start of the
treatment cycle
If the investigator determines that the toxicity is unlikely to further develop into a
serious or life-threatening event, the current dose will be continued without any
adjustments or treatment interruptions. In addition, dose adjustments or treatment
interruptions will not be performed for non-hemolytic anemia as the symptoms can be
alleviated through blood transfusions.
If the investigator determines that a toxicity is caused by a specific therapeutic drug,
then the dose adjustments of other drugs are not required
Discontinuation of one or two therapeutic drugs before PD will not affect the continued
treatment with other drugs
Dose reductions or adjustments of IBI305 or bevacizumab are not permitted.
Subsequent therapeutic dose will not be adjusted according to weight change, unless
the subject weight has changed by ≥10% from baseline
Once the dose of any chemotherapeutic agents is reduced, the original dose should no
longer be adopted
If any but not all of the therapeutic drug (IBI305, bevacizumab or chemotherapeutic
agents) treatments is interrupted due to toxicity, then this treatment will be considered
as a treatment cycle
If the administration of any one of the chemotherapeutic agents is delayed for more
than 3 weeks, the subject should permanently discontinue that chemotherapeutic agent

5.3.2 Dose adjustments of study drugs
Dose adjustments of IBI305 or bevacizumab are not permitted except for the adjustments
(adjusted to 7.5 mg/kg for maintenance monotherapy) specified in the study protocol. The dose
of IBI305 or bevacizumab is calculated according to the subject weight at baseline (prior to the
first dose), and remains unchanged throughout the study, unless the subject weight has changed
by ≥10% from baseline.
If an infusion reaction occurs during a 60-minute infusion, the infusion time should be extended
to 90 minutes for all subsequent infusions. Likewise, if an infusion reaction occurs during a 30-
minute infusion, the infusion time should be extended to 60 minutes for all subsequent infusions.
IBI305 or bevacizumab in combination with paclitaxel/carboplatin will be administered every
3-week treatment cycle for 6 cycles. If PD is not observed in subject during treatment, then the
subject will continue to receive IBI305 or bevacizumab as maintenance monotherapy every 3-
week treatment cycle until PD, unacceptable toxicity, withdrawal of informed consent, loss of
follow-up, death, or end of study (whichever comes first).
If IBI305 or bevacizumab is permanently discontinued due to unacceptable toxicity or subject
refusal to continue the study drugs during the combination therapy, then the subject will continue
to receive the chemotherapy (paclitaxel/carboplatin) until 6 treatment cycles are completed as
determined by the investigator. If any one of the chemotherapeutic agents (paclitaxel or carboplatin)
is prematurely discontinued due to unacceptable toxicity, the subject can continue to receive
IBI305 or bevacizumab treatment until PD, unacceptable toxicity, withdrawal of informed
consent, loss of follow-up, or death (whichever comes first).
When a Grade 3 or 4 IBI305- or bevacizumab-related toxicity is observed, the investigators
should determine whether to continue or terminate IBI305 or bevacizumab treatment according
to the followings:
First occurrence:
IBI305 or bevacizumab administration should be interrupted until toxicity symptoms return to
baseline level or are at least reduced to the Common Terminology Criteria for Adverse Events
(CTCAE) Grade 1 or lower (except for the special circumstances listed below)
Note that when Grade 4 febrile neutropenia and/or thrombocytopenia occur(s), IBI305
or bevacizumab administration should be interrupted until the symptoms return to
baseline levels or at least reduced to CTCAE Grade 1 or lower, since these events
increase the risk of hemorrhage.

Re-occurrence in re-administration:
If Grade 3 IBI305- or bevacizumab-related toxicity occurs again, the investigator
should assess the risk/benefit of study drug continuation for the subject. If such toxicity
re-occurs again after re-administration, IBI305 or bevacizumab should be permanently
discontinued
If Grade 4 IBI305- or bevacizumab-related toxicity occurs again, IBI305 or
bevacizumab should be permanently discontinued
Measures should be taken in the following special circumstances (classified based on CTCAE
version 4.03):
Hemorrhage
Subjects with Grade 3 or 4 hemorrhages should be treated accordingly and permanently
discontinue the study treatment
Thrombosis/embolism

Subjects with arterial thrombosis of any severity grades should permanently
discontinue the study treatment

Subjects with Grade 4 venous thrombosis should permanently discontinue the
study treatment

Subjects with Grade 3 venous thrombosis should interrupt the study treatment. If
the anticoagulant therapy at the planned therapeutic dose is < 2 weeks, the study
treatment should be interrupted until the anticoagulant therapy is completed. If
the anticoagulant therapy at the planned therapeutic dose is > 2 weeks, IBI305
or bevacizumab administration should be interrupted for 2 weeks, and the study
treatment can be restarted during the anticoagulant therapy if the following criteria
are met:
- INR is within the target range (usually 2-3) prior to restarting of study treatment
- Subjects must not have experienced Grade 3 or 4 hemorrhage since enrollment
- No signs of great vessel invasion or adjacency to great vessels from previous
tumor assessments
Note: Therapeutic dose of anticoagulant therapy is defined as the escalating dose of
warfarin or other anticogulants until INR is maintained at no less than 1.5 (usually

Posterior reversible encephalopathy syndrome (PRES)
There have been a few reports of subjects with signs and symptoms consistent with PRES after
study treatment. This is a rare neurological disease and its signs and symptoms include epilepsy,
headache, altered mental status, visual impairment, or cortical blindness, with or without
hypertension. Subjects with PRES should permanently discontinue the study treatment.
Proteinuria
Urinalysis should be performed prior to each dose of IBI305/bevacizumab unless a 24-hour
urinary protein test has already been done.
First occurrence of proteinuria:
After carrying out the urinalysis, if:
Urine protein is < 2+, continue study treatment as scheduled, no additional tests are
required.
≥2+ (urinalysis): perform 24-hour urinary protein test within 3 days prior to
administration:
•
24-hour urinary protein ≤2 g: continue study treatment as scheduled. and perform
urinalysis dipstick test before each scheduled dose.
•
24-hour urinary protein > 2 g: delay study treatment until 24-hour urinary protein ≤2 g.
and a 24-h urine protein test prior to each subsequent dose is performed until urine protein is
reduced to ≤1 g/24 h. Interrupt study treatment only when 24 h urine protein is > 2 g.
Second and subsequent occurrence of proteinuria:
< 3+ (urinalysis): continue study treatment as scheduled, no additional tests indicated.
≥3+ (urinalysis): perform 24-hour urinary protein test within 3 days prior to
administration:
• 24-hour urinary protein ≤2 g: continue study treatment as scheduled.
• 24-hour urinary protein > 2 g: delay study treatment until 24-hour urinary protein ≤2 g.
and a 24-h urine protein test prior to each subsequent dose is performed until urine protein is
reduced to ≤1 g/24 h. Interrupt study treatment only when 24 h urine protein is > 2 g.

If gastrointestinal perforation occurs, appropriate measures should be taken and the study
treatment should be permanently discontinued.
Wound healing complications
The study treatment should not begin within 28 d after a major surgery, or before the surgical
wound is fully healed. If a complication of wound healing occurs during study treatment, the
study treatment should be interrupted until the wound is fully healed. If an elective surgery is
required, the study treatment should be interrupted.
Abdominal abscess or fistula
If abdominal abscess or fistula occurs, the study treatment should be discontinued. However, the
investigator will determine whether study treatment will be continued if the above AE is resolved.
Infusion-related and allergic reactions:
Infusion-related reactions after first dose of the study drug is uncommon (< 3%), and the incidence
of a severe reaction is only 0.2%.
If a mild (grade 1 or 2) reaction (such as fever, chills, headache, and nausea) occurs, pretreatment
prior to subsequent administration should be performed and infusion time should not be reduced.
If the subject is well-tolerated during infusion after pretreatment, the infusion time can be
reduced by 30 minutes (+10 minutes) for subsequent administration with pretreatment. If an
infusion-related AE occurs during a 60-minute infusion, the subsequent infusion should be
completed within 90 minutes (+15 minutes) with pretreatment. Likewise, if an infusion-related
AE occurs during a 30-minute infusion, the subsequent infusion should be completed in 60 minutes
(+10 minutes) with pretreatment. If a subject has a grade 3 infusion-related reaction, the study
treatment should be interrupted and not be restarted on the same day. However, since there lacks
the dose adjustment method for grade 3 infusion-related reactions, the investigators may decide
to either discontinue the study drug or perform pretreatment, and complete the infusion within
90 minutes (+15 minutes). If an adverse reaction still occurs during a 90-minute infusion, the
infusion should be continued at a slower rate and then gradually returned to a 90-minute infusion.
If the investigator is uncertain about the handling, the study treatment should be discontinued.
When the study treatment is restarted, the subject should be closely monitored based on routine
clinical practice until the possible time of adverse reaction has passed. If a subject has a grade 4
infusion-related reaction, the study treatment should be discontinued.
An allergic reaction is defined as the vascular collapse or shock (systolic BP < 90 mmHg,
unresponsive to rehydration) that occurs within 30 minutes of a study drug infusion caused by
an allergy, with or without respiratory distress. Skin reactions include pruritus, urticaria, and
angioedema. Subjects with allergic reactions should discontinue the study treatment.

5.3.3 Dose adjustments of chemotherapy
Paclitaxel and carboplatin should be administered according to the study site guidelines and local
prescribing information. For the specific information for use, preparation, and storage of
paclitaxel and carboplatin, refer to the prescribing information and local dosing information.
Carboplatin-based chemotherapies have a relatively high incidence of emesis. Therefore,
antiemetics for prophylaxis can be used.
Hematological toxicity:
Absolute neutrophil count (ANC; dose can only be reduced when febrile neutropenia occurs.
ANC must be ≥1.5 × 109/L and platelet count must be ≥100 × 109/L on D1 of each treatment
cycle). Once the chemotherapeutic dose is reduced due to febrile neutropenia or
thrombocytopenia (platelet count < 25 × 109/L or 50 × 109/L with hemorrhage or blood
transfusion required), the original dose should no longer be adopted. If the dose reduction is
required for the third time, the chemotherapy should be immediately discontinued.

If the dose adjustment is required when ANC and thrombocytopenia occur concurrently, the low-
dose chemotherapy should be adopted.
Chemotherapy may be delayed for up to 3 weeks. If after the chemotherapy has been delayed for
3 weeks, ANC does not reach ≥1.5 × 109/L and platelet count does not reach ≥100 × 109/L on
D1 of the scheduled chemotherapy, the chemotherapy should be permanently discontinued. If the
above values have been reached, the next course of chemotherapy should be continued.

The investigator should monitor the subject closely for toxicity with particular attention to early
and evident signs of myelosuppression, infection, or febrile neutropenia to timely and
appropriately treat the complications.
Subjects should be informed to pay attention to these signs and receive treatment as soon as possible.
If the chemotherapy must be interrupted due to hematological toxicity, the complete blood count
should be performed regularly (including WBC differentials) until all the counts reach the
minimum requirements for treatment continuation. Thereafter the scheduled treatment plan will
be performed.
Dose adjustments are not required for anemia. However, treatment based on guidelines of each
clinic should be performed.
Gastrointestinal toxicity
Antiemetics will be used to control nausea and/or emesis. If grade 3 or 4 nausea and/or emesis
occur(s) despite of antiemetics, the chemotherapeutic dose should be reduced by 20% for the
next treatment cycle. The dose should be returned to the initial level as possible if the subject is
tolerated.
If the subject experiences stomatitis on D1 of any treatment cycle, the chemotherapy should be
interrupted until the symptoms resolve. If the stomatitis has not resolved after 3 weeks, the
chemotherapy should be permanently discontinued (refer to CTCAE version 4.03). If an acute
Grade 3 stomatitis occurs, the chemotherapeutic dose should be reduced to 75% of the proposed
dose when symptoms resolve.
Hepatotoxicity (Paclitaxel)
The paclitaxel dose should be determined based on the lab values measured on D1 of each
treatment cycle.

If paclitaxel is interrupted due to hepatotoxicity, carboplatin should also be interrupted until
paclitaxel is restarted. Paclitaxel will be interrupted for up to 3 weeks. If the subject's hepatic
function does not return to the acceptable ranges in 3 weeks, paclitaxel should be permanently
discontinued. The carboplatin dose will not be adjusted when hepatotoxicity occurs.
The investigators should avoid PD due to abnormal hepatic enzyme levels as possible. If PD
occurs, all the study drugs should be permanently discontinued, including chemotherapy.
Cardiovascular toxicity (paclitaxel)
The arrhythmia in subjects was infrequent in previous clinical studies. However, most subjects
were asymptomatic and electrocardiographic monitoring was not required. Asymptomatic
transient bradycardia was observed in 29% of subjects, but significant atrioventricular block was
rare. Cardiac events should be treated as follows:
Asymptomatic bradycardia: no intervention indicated
Symptomatic arrhythmia during infusion: Discontinue paclitaxel infusion and perform
routine treatment of arrhythmia. Discontinue subsequent paclitaxel treatment.
Document this AE in the AE Report Form of eCRF.
Chest pain and/or symptomatic hypotension (< 90/60 mmHg or rehydration therapy
required): discontinue the paclitaxel infusion. Perform electrocardiography (ECG). If
hypersensitivity reaction is suspected, administer diphenhydramine and dexamethasone
via intravenous infusion. If the chest pain is not considered as cardiogenic, epinephrine
or bronchodilators will be administered. Document this AE in the AE Report Form of
eCRF. Discontinue subsequent paclitaxel treatment and provide symptomatic treatment.
Consult a cardiologist if needed.
Neurotoxicity (paclitaxel)
The dose of paclitaxel should be adjusted according to Table when neuropathy occurs. The dose
adjustment of carboplatin is not needed when neurotoxicity occurs.

Once the dose is reduced due to neurotoxicity, the original dose should no longer be adopted.
If the neurotoxicity does not return to grade 1 after paclitaxel interruption for 3 weeks, paclitaxel
should be permanently discontinued.
Allergic reactions/hypersensitivity reactions (paclitaxel)
Note: Prophylaxis for hypersensitivity reactions (see below) and close monitoring of vital signs
are recommended for subjects with history of mild to moderate hypersensitivity reactions when
hypersensitivity reactions reoccur.
Mild symptoms: complete paclitaxel infusion. Close monitoring; no treatment indicated.
Moderate symptoms: Interrupt paclitaxel infusion, administer diphenhydramine 25–
50 mg and dexamethasone 10 mg via intravenous infusion. Once symptoms have
resolved, resume paclitaxel infusion at a slower rate (20 mL/hour for 15 minutes, then
at 40 mL/hour for 15 minutes, and if no further symptoms develop, continue at original
rate until infusion is complete). Document this AE in the AE Report Form of eCRF. If
symptoms reoccur, interrupt the paclitaxel infusion and permanently discontinue
subsequent paclitaxel infusion.
Severe and life-threatening symptoms: Interrupt paclitaxel infusion, administer
diphenhydramine and dexamethasone via intravenous infusion (as above). Use
epinephrine or bronchodilators if indicated. Document this AE in the AE Report Form
of eCRF. Subsequent courses of paclitaxel infusion should be permanently
discontinued.
Moderate or severe hypersensitivity reactions should be documented as AEs.
Other toxicities
If other unmentioned grade 3–4 toxicities occur, the chemotherapy should be interrupted until
symptoms resolve or return to grade 1. Thereafter restart the infusion at 50% of the original dose
(which should no longer be adopted). If the toxicity does not return to grade 1 after an
interruption for 3 weeks, the chemotherapy should be permanently discontinued. Dose
adjustments are not recommended for grade 1 and 2 toxicities.

to disclose any information regarding treatment allocation to the subject, the subject's family
members, or other personnel including the physician and the relevant study staff.
Unblinding: Subject unblinding should only be performed after database locking.
Emergency unblinding: In case of an emergency where the investigator must know the
medication given to a particular subject, the investigator will unblind the subject via the IWRS
and immediately inform the sponsor and CRO. The reasons for unblinding, date, and outcomes
should be documented in the source document and eCRF of the subject.
5.9 Concomitant Medications and Treatments
All medications except for the study drugs, including other chemotherapies not specified in the
study, Chinese herbal medicines, and other non-traditional therapies, are considered concomitant
medications. All concomitant medications used within 30 days prior to screening should be
documented in the eCRFs, including the information of generic name, route of administration,
start date, end date, and indication.
5.9.1 Prohibited treatment
No other anti-tumor therapies or medications with anti-tumor indications, including Chinese
herbal medicine, radiotherapy, or other investigational drugs, are allowed during this study other
than IBI305, bevacizumab, paclitaxel, and carboplatin.
Severe myelosuppression is possible after chemotherapy. Granulocyte colony-stimulating factor
or granulocyte-macrophage colony-stimulating factor are not allowed to be used prophylactically
in the first treatment cycle.
5.9.2 Permitted treatment
Prophylactic use of anti-emetics, glucocorticoids, or other treatments targeting toxicities is permitted
during the study. Unconventional treatments (such as acupuncture) and vitamins/microelements are
permitted if their use does not affect the study endpoints as determined by the investigators.

Starting from the 2nd chemotherapy cycle, granulocyte colony-stimulating factor or granulocyte-
macrophage colony-stimulating factor are allowed to be used prophylactically to prevent severe
myelosuppression.
Anti-viral therapy was permitted whenever necessary.
Stable doses of anti-epileptic drugs were permitted.
Radiotherapy for bone metastasis was permitted provided that the radiotherapy field did not
include the target lesion
5.9.3 Treatment after study treatment
Subsequent therapy after the end of study treatment should be determined by the subject's
attending doctor.
5.10 Treatment Compliance
Subjects should receive treatment at the study site. The dose and time of administration of
IBI305 or bevacizumab and paclitaxel/carboplatin should be documented in the source records
and eCRFs during each treatment cycle. Reasons for dose adjustments, therapy delay, and
therapy discontinuation should be documented. Treatment compliance is monitored by
medication dispensing and return records, medical records, and eCRFs.
5.11 Drug Return and Destruction
The containers, vials, infusion bags, and syringes of used and partially used drugs can be
destroyed on-site according to the appropriate guidelines and operating procedures established
by study sites and local agencies.
Unless the contents have significant safety issues requiring immediate destruction in accordance
with local regulations, all the unused drugs should be returned and destroyed based on the
requirements of sponsor.
5.12 Study Drug-Related Records
The designated personnel of the study sites should make timely records of receiving, dispensing,
using, storing, returning, and destroying the study drugs in accordance with the relevant
regulations and guidelines.

6.13 Tumor Assessment
Imaging tests (CT or MRI) of the brain, chest, abdomen, and pelvis are required at baseline. If
these tests are performed within 28 days prior to the first dose of the study drug, they do not need
to be repeated unless the investigator believes that there have been changes in the subject's tumor
burden. After the start of treatment, imaging tests are performed once every 6 weeks (±7 days)
and have to be completed within 7 days prior to the scheduled visits, until progressive disease,
start of other treatment, withdrawal of informed consent, loss to follow-up, death, or study
completion. The same method of imaging test was used at baseline and during follow-up.
Imaging evaluations of the chest, abdomen, and pelvis are required.
The investigator should perform a tumor assessment based on RECIST v1.1 (Section 13.3) prior
to each dose to determine whether the subject should continue with the next round of treatment.
An independent review committee will also assess the tumor response (Section 11.1.1). Imaging
tests will not be rescheduled if the study drugs or chemotherapeutic agents are interrupted due to
toxicities. Every effort should be made to continue the schedule for imaging tests even for
subjects who discontinue one or two study treatment(s) due to drug-related toxicities.
If subject experience PD according to the RECIST v1.1 criteria, the attending doctor should
discuss with the subject regarding subsequent routine cancer therapies.
6.14 Clinical Laboratory Evaluations
Clinical laboratory tests will be conducted at the laboratories of each study site. Sample collection
and analysis should be performed according to the requirements of each laboratory.
The following laboratory tests should be conducted according to the study procedures (Table 1.

➢
Pregnancy test: Serum/urine pregnancy tests are performed on women of
childbearing age during screening and the end-of-treatment visit.
These tests are carried out at the laboratory of each trial site.
For subsequent visits, all laboratory tests need to be completed within 3 days prior to the
administration. During the study, the frequency of these laboratory tests will be increased if
safety is a concern. The investigator should review the laboratory test results throughout the
study to determine whether the results are clinically significant. The investigator should assess
the changes in laboratory test results. If the investigator considers a laboratory test result to be
abnormal and of clinical significance, it is considered as an AE.
6.15 Vital Signs, Physical Examinations, and Other Safety Assessments
6.15.1 Vital signs
Vital signs include pulse, BP, temperature, and respiratory rate. The subject must rest for at least

7 STUDY ASSESSMENTS
7.1 Efficacy Assessment
7.1.1 Primary efficacy endpoint

Objective response rate (ORR)
ORR will be assessed using RECIST v1.1. ORR is defined as the proportion of subjects whose
tumor volume has reduced to a predetermined value for a minimum time limit, including patients
who achieved complete response (CR) and partial response (PR). The cut-off date for the
analysis of primary efficacy endpoint in this study is 18 weeks after subject randomization.
7.1.2 Secondary efficacy endpoints

Duration of response (DOR)

Progression-free survival (PFS)

Disease control rate (DCR)

Overall survival (OS)
Each endpoint will be assessed using RECIST v1.1.
DOR is defined as the time from initial tumor response (CR or PR) to PD or death before PD;
Subjects with CR or PR who do not progress or die will be censored on the date of the last tumor
assessment.
PFS is defined as the time from the date of randomization to the date of PD or death; Subjects
who do not progress or die will be censored on the date of the last tumor assessment.
DCR is defined as the proportion of patients whose tumor volume has reduced to a
predetermined value for a minimum time limit, including patients who achieved CR, PR, and SD.
OS is defined as the time from the date of randomization to the date of death of any cause. For
subjects that are alive on the date of study completion or are lost to follow-up, their survival time
will be censored at the date of last contact.

7.2 Safety Assessments
7.2.1 Adverse events
7.2.1.1 Definition
Adverse event
An AE refers to any untoward medical occurrence in a subject after signing the informed consent
form, and does not necessarily have a causal relationship with the treatment. Thus, an AE can be
any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or
disease, whether considered drug related.
Abnormalities resulting from PD are not considered as AEs.
Serious adverse event
A SAE refers to an AE meeting at least one of the followings:
(1) Lead to death, except for deaths caused by PD.
(2) Life-threatening (a "life-threatening event" is defined as an AE when the subject is at
immediate risk of death at the time, but does not include the case that may lead to death
only when the event worsens).
(3) Requires hospitalization or prolonged hospitalization, excluding an emergency or
outpatient visit. Subjects with existing diseases or conditions prior to the enrollment
that do not worsen during the study, and having hospitalization and/or surgery that was
scheduled before the study or during the study do not meet the SAE criterion.
Hospitalizations resulting from PD are not considered as SAEs.
(4) Results in permanent or severe disability/incapacity.
(5) Results in congenital anomalies/birth defects.
(6) Other important medical events: The event that does not result in death, is not life-
threatening or does not require hospitalization, but may jeopardize the health of
subjects and require medical intervention to prevent the SAEs above, is considered as
an SAE
7.2.1.2 Severity of adverse events
The severity of AEs is evaluated using the 5-level criteria of NCI CTCAE v4.03.
For AEs not included in CTCAE v4.03, use the following CTCAE general guidelines:

7.2.1.4 Serious adverse event reporting
SAEs that occur from the signing of informed consent form until 90 days (inclusive) after the last
dose should be reported. The investigator must fill out the "CFDA SAE Report Form", regardless
of whether it is the initial report or a follow-up report, and sign and date the form. The
investigator must report the SAE to the sponsor, CFDA, and ethics committee within 24 hours of
noticing the event. The contact information for reporting is shown in the table below.
For SAEs occurring outside of the above-mentioned period, those considered related to the
investigational drug shall also be reported to the sponsor.
The investigator must submit the completed SAE report form to the sponsor within 24 hours of
noticing the event. The investigator shall urgently perform visit on missing information and
provide a complete SAE report for events that result in death or are life-threatening.
The investigator should also report the event to the CFDA, health administration departments,
and ethics committees in accordance with the regulations.
When submitting the SAE report by email, it is recommended for the investigator to encrypt the
report file and send the report file and password in separate emails.

The investigator is responsible for providing appropriate medical treatment for all AEs (Indicate
the actions taken, such as suspension/termination of the investigational drug, dose modification,
drug therapy, etc.). When an AE occurs, the investigator should actively take appropriate
measures to ensure the safety of the subject. All AEs observed from the signing of the ICF
to the time specified in the protocol (Table 2) must be followed.
The investigator should report any SAE that occurs after the time specified in the protocol (Table 2)
and is suspected of being related to the investigational drug to the sponsor.

7.2.1.7 Pregnancy
Bevacizumab may be harmful to the fetus. Subjects or female partners of male subjects must use
an effective form of contraception during the 6 months after the last dose.
During the study, if a female subject exposed to the study drug becomes pregnant, she must
discontinue study treatment. The investigator must report to the sponsor within 24 hours of
noticing the event and submit the "Innovent clinical Study Pregnancy Report/Follow-Up Form".
During the study, if a female partner of a male subject exposed to the study drugs becomes
pregnant, the subject will continue in the study. The investigator must report to the sponsor
within 24 hours of noticing the event and submit the "Innovent Clinical Study Pregnancy
Report/Follow-Up Form".
The investigator must continuously monitor and visit on the outcome of the pregnancy until 8
weeks after the subject gives birth. The outcome should be reported to the sponsor.
If the outcome of the pregnancy is stillbirth, spontaneous abortion, fetal malformation (any
congenital anomaly/birth defect), or medical abortion, it should be considered as an SAE and the
event is required to be reported in accordance with SAE procedures and time limits.
If the subject also experiences a SAE during the pregnancy, the CFDA SAE Report Form should
also be filled out and reported according to SAE's procedures.
7.2.1.8 Time limits of documenting and reporting AEs
All AEs occurring from the time the subject signs the informed consent form to the time
specified in the protocol (Table 2) (including SAEs and non-SAEs), regardless of their severity,
must be collected and recorded on the AE page of the eCRF.
The investigator must fill out all the required information, including the description of the AE,
start date, end date, severity, measures taken, outcome, seriousness, and causality with the
investigational drug. Each AE should be documented separately.

7.2.1.9 Precautions for AE documentation
Diagnosis, signs, and symptoms
If a diagnosis is already made, the eCRF should record the diagnosis instead of individual
symptoms and signs (such as hepatic failure rather than jaundice, transaminase increased, and
asterixis). However, if the signs and symptoms cannot be attributed to a definitive diagnosis, each
independent event should be documented in the eCRFs as an AE or SAE. Update the report with
visit information if a diagnosis is confirmed later.
AEs secondary to other events
Generally, AEs secondary to other events (such as result of another event or clinical sequelae)
should be documented as the primary event, unless the event is severe or an SAE. However,
clinically significant secondary events should be recorded as independent adverse events in the
eCRFs if they occur at different times than the primary event. If the relationship between events is
unclear, document them as separate events in the eCRFs.
Ongoing or recurrent AEs
An ongoing AE refers to an event that does not resolve and is ongoing between two assessment
time points. These AEs should only be documented once in the eCRFs. The initial severity should
be documented, and the information should be updated if the event exacerbates.
Recurring AEs refer to AE that have resolved between the two time points of assessment but
subsequently occur. These events should be independently documented in the eCRFs.
Abnormalities in laboratory tests/vital signs
All clinically significant laboratory test abnormalities should be reported as AEs. It is the
responsibility of the investigator to review all abnormal laboratory test results, and to make
medical judgments as whether each abnormal laboratory test result should be reported as an AE.

Death
During the entire course of the study, all the deaths that occurred within 90 days after the last dose
were documented in the Death Report Form in the eCRFs, regardless of the causality with the
investigational drug.
When recording a death event, if the cause of death is clear, the cause of death is recorded as an
adverse event with the result of the adverse event being death, and the event is reported as an SAE;
if the cause of the death is unknown at the time of reporting , "Death with Unknown Cause" should
be recorded on the Adverse Event Form of the eCRF and the "Death with Unknown Cause" should
be reported as an SAE first before further investigation is carried out to find the exact cause of
death.
Pre-existing medical conditions
Symptoms/signs presenting during the screening period will be recorded and reported as AEs only
if their severity, frequency, or property becomes aggravated (except for worsening of the studied
disease). The relative change should be documented, such as "increased frequency of headaches".
Hospitalization and prolonged hospitalization, or surgery
Any AE that results in hospitalization or prolonged hospitalization should be documented and
reported as an SAE, except for the following situations:

Hospitalization or prolonged hospitalization as required by study protocol (such as for dose
administration, efficacy evaluation, etc.)

Hospitalization due to a pre-existing medical condition that remains stable, e.g. elective
surgery/therapy scheduled prior to the study.
However, elective surgery/therapy required because of the exacerbated condition during the study
(e.g. surgery/therapy required earlier than scheduled) should be considered as an AE.
The investigator should fill in all required information, including AE terms
(diagnostic terms, or the record of symptoms and signs including laboratory test abnormalities if
there is no diagnosis), start date, end date, severity level, whether it is an AESI, measures taken for
the investigational product, treatment given for the AE, outcome, seriousness, and relationship with
the investigational product. If the signs and symptoms cannot be attributed to a definitive diagnosis,
each AE should be documented independently.

Progressive disease
A progressive disease is defined as the worsening of subject condition caused by the primary tumor
that the investigational drug is targeting, the appearance of new lesions, or the progression of the
primary lesion. Expected progressive disease should not be reported as an AE. Any deaths, life-
threatening events, hospitalization or prolonged hospitalization, permanent or significant
disability/incapacity, congenital anomaly/birth defects, or other important medical events caused
by progressive disease should not be reported as an SAE
8 STATISTICS
8.1 Sample Size Determination
A number of 218 subjects for each group (436 subjects in total) can provide 80% test power to
confirm the clinical equivalence between the treatments of IBI305 in combination with
paclitaxel/carboplatin and bevacizumab in combination with paclitaxel/carboplatin.
The sample size is estimated based on the following assumptions:

The ORRs between IBI305 and bevacizumab group are equivalent

The ORR of subjects in the bevacizumab groups is set to 50.0%

The equivalence margin is taken as (-12.5%, 16.7%)

The significance level of the two one-side test is 0.05

1:1 randomization
Based on the above hypotheses, a number of 218 subjects for each group is required (436
subjects in total). The sample size was estimated using PASS 2013.
8.2 Statistical Population
Intention-to-Treat (ITT): All randomized subjects.
Full Analysis Set (FAS): All randomized subjects who received at least one dose of the study
treatment. This dataset is used as the primary analysis set for efficacy assessment.
Per-Protocol (PP): Based on the FAS, subjects with the predetermined minimum drug exposure
and without any predetermined major protocol deviations. This dataset is used as the secondary
analysis set for efficacy assessment.
Safety set (SS): Includes all randomized subjects who received at least one dose of the study
treatment and have safety evaluation data. This data set is used for the safety evaluation of this study.

8.3 General Principles for Statistical Analyses
For continuous variables, descriptive statistics should include the count, mean, standard
deviation, median, maximum, and minimum. For categorical variables, descriptive statistics will
include the frequency as well as the absolute or relative percentage. Statistical analyses will be
carried out using SAS 9.4.
8.4 Statistical Methods
8.4.1 Adjustments for covariates
Not applicable.
8.4.2 Managing dropouts and missing data
The analyses of primary and secondary endpoints will include data from dropouts. The management
of missing data is described in the Statistical Analysis Plan.
8.4.3 Multi-center study
Since this is a multicenter study, the primary endpoint (ORR) will be listed according to study
sites and treatment groups. However, individual equivalence analysis will not be conducted.
Trial sites with fewer than 5 ITT subjects per treatment group will need to be combined for
analysis. Details will be discussed in the data review meeting.
8.4.4 Multiple comparisons and adjustments to multiplicity
The α adjustment for multiple comparisons is not considered.

The number and percentage of subjects in each analysis set are calculated based on treatment groups.
The number and percentage of protocol deviations are calculated based on treatment groups.
8.5.2 Demographics and other baseline characteristics
Demographic information such as age, height, sex, and weight, and other baseline characteristics
such as disease history (including NSCLC diagnosis, staging, previous cancer treatment, and
target and nontarget lesions) are summarized using descriptive statistics.
8.5.3 Compliance and drug exposure
The required dose and the actual dose must be documented in the eCRF. Subject compliance is
calculated based on the ratio of the actual dose (number of doses) to the required dose (number
of doses). Subject compliance is classified into the following categories: < 80%, 80–120%, and >
120%. The number and percentage of subjects in each category will be summarized.
8.5.4 Efficacy
The efficacy analysis will be based on the FAS. Results of the PP set will also be presented.
8.5.4.1 Primary efficacy endpoint
The primary objective of this study is to determine the clinical equivalence between IBI305 +
paclitaxel/carboplatin and bevacizumab + paclitaxel/carboplatin for the treatment of advanced or
relapsed non-squamous non-small cell lung cancer (NSCLC). The primary endpoint is objective
response rate (ORR). ORR is defined as the incidence of patients with confirmed complete
response (CR) or partial response (PR), when a validated imaging method and RECIST v1.1
are used to evaluate target and non-target lesions. Subjects without tumor assessments beyond
baseline will be considered unresponsive to treatment. Subjects qualified for the evaluation of
CR or PR must have at least one measurable lesion according to RECIST v1.1. The evaluation
of clinical equivalence will be based on the ORR provided by the independent review committee
(IRC). Results provided by the investigator will be used for sensitivity analysis.
Clinical equivalence will be declared if the 90% confidence interval of the difference in ORR
between IBI305 and bevacizumab groups falls within the preset margin of (-12.5%, 16.7%).
The ORR and corresponding 95% confidence interval of the two treatment groups, the ORR
difference and the 90% confidence interval, as well as the ORR ratio between the two groups and
the 90% confidence interval will be estimated using the generalized linear model (GLM, which
includes treatment groups and stratification factors).

8.5.4.2 Secondary efficacy endpoints
The secondary endpoints for this study include DOR, DCR, progress-free survival (PFS), and
overall survival (OS).
DCR is defined as the incidence of patients with confirmed complete response (CR), partial
response (PR), and stable disease (SD), when a validated imaging method and RECIST v1.1 are
used to evaluate target and non-target lesions.
DOR is defined as the time from initial tumor response (CR or PR) to PD or death; Subjects with
CR or PR who do not progress or die will be censored on the date of the last tumor assessment.
OS refers to the time from the date of randomization to the date of death (of any cause). For
subjects who are still alive at the time of the analysis, their survival time is censored on the last
known alive date. PFS refers to the time from the date of randomization to the date of first
documented PD or death, whichever occurs first. The investigator will assess PD using RECIST
v1.1. Subjects who do not progress or die will be censored on the date of the last tumor
assessment. Subjects without tumor assessments after baseline are censored on their date of
randomization.
Median OS and its 95% CI will be estimated using the Kaplan-Meier method. The survival curve
will be plotted. The hazard ratio (HR) between the two groups and its 95% CI will be estimated
using a Cox model. The Cox model includes treatment groups and stratification factors. DOR
and PFS will be analyzed using the same method as for OS. DCR will be analyzed using the
same method for primary efficacy endpoints, but an equivalence test will not be conducted.
8.5.4.3 Sensitivity analysis
The center effect (fixed or random) will be considered in the primary and secondary endpoints
analysis models (GLM or Cox).
8.5.4.4 Antibody and efficacy analysis
Subjects who develop antibodies during the clinical study will be summarized in detail. The
difference in efficacy between subjects with and without antibodies will be compared if
necessary.
Changes in PK parameters and steady-state trough concentrations of subjects with positive ADA
are analyzed.
8.5.5 Exploratory analysis
Pharmacodynamic parameters: The changes in the serum VEGF level at different time points are
described, and inter-group comparisons are carried out when necessary (based on the PD dataset)

9 QUALITY ASSURANCE AND QUALITY CONTROL
According to GCP principles, the sponsor is responsible for implementing and maintaining
quality assurance and quality control systems based on standard operating procedures (SOP),
to ensure that the implementation of the clinical trial and the collection, documentation, and
reporting of trial data is in accordance with the protocol, GCP, and applicable regulatory
requirements.
To ensure that the data is reliable and processed correctly, there should be quality control for
every step during the data processing.
In addition, the Clinical Quality Assurance (CQA) Department of the sponsor and/or CRO may
conduct regular audits of the study process, including but not limited to auditing the study site,
on-site visits, central laboratory, suppliers, clinical database, and the final clinical study report.
Regulatory authorities may also conduct inspections during the trial or at any time after the trial
is completed. The investigator and the research institution must allow the sponsor's representative
and regulatory authorities to review source data.
9.1 Clinical Monitoring
The sponsor has authorized Wuxi Clinical Co., Ltd. to conduct clinical monitoring for this study.
The clinical research associate (CRA) should follow the SOPs of Wuxi Clinical Co., Ltd. when
carrying out monitoring, and has the same rights and responsibilities as the sponsor's monitor.
The CRA should maintain regular communication with the investigator and the sponsor.
Before the start of the study, the associate monitor assess the qualifications of each study site,
and report issues related to facilities, technical equipment, or medical staff to the sponsor. During
the study, the CRA will be responsible for confirming whether written informed consent is
obtained from all subjects, and whether data documentation is accurate and complete. At the
same time, the CRA will compare data entered in to the eCRF with source data, and notify the
investigator of any errors or omissions. The CRA will also verify protocol compliance of the
study site, as well as the dispensing and storage of investigational drugs to ensure protocol
requirements are met.
The monitoring visit will be conducted in accordance with applicable statutes and regulations.
Each site receives regular monitoring visits from the time the subjects are enrolled. The CRA
should submit a written report to the sponsor after each monitoring visit to the study site.

9.2 Data Management/Coding
The Data Management and Biostatistics Department of Wuxi Clinical Co., Ltd will process data
generated from this study in accordance with relevant SOPs.
This study will use an electronic data capture (EDC) system. Trial data will be entered into the
eCRF by the investigator or authorized study personnel. Prior to launching of the study site or
data entry, the investigator and authorized study personnel will receive appropriate training, and
appropriate safety measures will be taken.
All data are input in Chinese. The eCRF should be completed during or soon after each visit, and
should be constantly updated to ensure that it reflects the latest status of the subject. To avoid
discrepancies in outcome assessments between different evaluators, ensure that baseline and all
subsequent efficacy and safety assessments for the same subject are performed by the same
person. The investigator must review trial data to ensure the accuracy and correctness of all data
entered into the eCRF. During the study, the investigator should document any evaluations that
are not conducted, or any information that is not available, applicable, or known. The
investigator needs to sign all verified data electronically.
The CRA will review the eCRF, and evaluate its completeness and consistency. The CRA will
also compare the eCRF with the source documents to ensure the consistency of critical data. Data
entry, corrections, or modifications are completed by the investigator or designated staff. The
CRA do not have access to data entry. The data in eCRF is submitted to the data server, and any
changes to the data will be documented in the audit trail, including the reason for the change, the
name of the operator, as well as the time and date of the change. The roles and permissions of
study personnel responsible for data entry will be predetermined. The CRA or data manager will
submit data queries in the EDC system, and study personnel shall respond to the queries. The
EDC system will record the audit trail of each query, including the name of the investigator, as
well as the time and date.
Unless otherwise specified, the eCRF should be considered simply as a form for data collection
and not a source document. A source file is used by the investigator or hospital, relevant to the
subject, and can prove the existence of the subject, inclusion criteria, and all records of
participation in the study, including laboratory records, ECG results, memorandum, pharmacy
dispensing records, and subject folders.

Confidential
The investigators are required to maintain all source documents and to offer the documents to the
CRA for review during each visit. In addition, the investigator must submit a complete eCRF for
each subject, regardless of the duration of the subject's participation in the study. The study
number and subject number in all supporting documents (such as laboratory records or hospital
records) submitted along with the eCRF should be carefully verified. All personal privacy
information (including the name of the subject) should be deleted or be made indecipherable in
order to protect subject privacy.
The investigator could be automatically added to the eCRF with his/her user ID. The investigators
verify that the record have been reviewed and that the data are accurate with an electronic
signature. The electronic signature is completed with the investigator's user ID and password.
The system automatically attaches the date and time of the signature. The investigator could not
share the user ID and password with other personnel. If data in the eCRF need to be modified,
the procedures defined by the EDC system have to be followed. All modifications and reasons
for the changes are recorded in the audit trail.
Training on the EDC system will be provided to study personnel at the study site.
Adverse events, and concurrent diseases/medical history will be coded. The medical dictionary
used for coding will be described in the Clinical Study Report (CSR).
9.3 Audits and Inspections
The sponsor or its representative (WuXi Clinical Co., Ltd) may conduct quality assurance audits
on the study site, database, and relevant study-related documents. Also, regulatory authorities
may also decide to inspect the study site, database, and relevant study-related documents at its
own discretion. The aim of audits and inspections is to systematically and independently check
all study-related procedures and documents to ensure that the clinical study is being carried out
in accordance with requirements of the trial protocol, GCP, Declaration of Helsinki, and
applicable regulations. The investigator must inform the sponsor immediately when an
inspection notice is received from the regulatory authorities.

independent ethics committee (IEC) of each study site. The trial protocol, informed consent form
(ICF), investigators brochure, subject recruitment material or advertisements (if applicable), as
well as other documents required by regulations must be submitted to the IEC for approval. Prior
to the start of the study, written approval from the IEC must be obtained and provided to the
sponsor. The IEC approval must clearly state the title, number, and version of the study protocol
as well as the version of other documents (e.g. ICF) and the date of approval. The investigator
must notify the sponsor of the IEC's written comments concerning delays, suspension and re-
approval.
The study site must follow the requirements of the IEC. IEC requirements may include
submitting the revised protocol, ICF, or subject recruitment material to the IEC for approval,
local regulatory requirements for safety reports, and regular reports, updates, and submitting the
final report as per IEC requirements. The above documents as well as the IEC approval must be
provided to the sponsor or its designated personnel.
10.2 Implementation of Ethical Principles
The study process and the acquisition of informed consent should comply with the Declaration of
Helsinki, relevant GCP requirements (CPMP/ICH/135/95), and applicable statutes and
regulations related to drugs and data protection in the country in which the study is conducted.
The GCP is an international ethical and scientific quality standard for designing, conducting,
recording and reporting clinical trials that involve the participation of human subjects. To protect
the rights, safety, and healthy of subjects, this study will be carried out in accordance with GCP
and applicable national regulations, as well as ethical principles outlined in the Declaration of
Helsinki.

10.3 Subject Information and Informed Consent
Prior to undergoing any study procedure, the ICF should be used to explain to potential participants
the potential risks and benefits of this study. The informed consent form should be in a language
that is simple and be easy to understand. The ICF should state that informed consent is voluntary,
emphasize the potential risks and benefits of participating in this study, and that the subject may
withdraw from the study at any time. The investigator may only enroll a subject after fully
explaining the details of the study, answering questions to the subject's satisfaction, giving
the subject sufficient time for consideration, and obtaining written consent from the subject or
his/her legal representative. All signed ICF must be retained in the investigator's documents or
the subject's folder.
The investigator is responsible for explaining the contents of the ICF and obtaining the ICF
signed and dated by the subject or his/her legal representative prior to starting the study. The
investigator should provide the subject with a copy of the signed ICF. The investigator must
document the informed consent process in the source document of the trial.
10.4 Protection of Subject Data
Information about data protection and privacy protection will be included in the ICF (or in some
cases, in a separate document).
Study personnel must ensure that the privacy of clinical trial subjects is protected. In all
documents submitted to the sponsor, the clinical trial subjects must only be identified with
subject number and not with the full name.
Additional precautions should be taken to ensure the confidentiality of the documents and
to prevent the identification of subjects based on genetic data. However, under special
circumstances, some personnel may be permitted to see the genetic data and personal
identification number of a subject. For example, in the event of a medical emergency, the
sponsor, designated physician, or investigator will have access to the subject identification code
and the subject's genetic data. In addition, regulatory agencies may request access to relevant
documents.

MEASURABILITY OF TUMOR AT BASELINE
1.1
Definitions
At baseline, tumor lesions/lymph nodes will be categorized as measurable or not measurable as
follows:
1.1.1
Measurable
Tumor lesions: must be accurately measured in at least one dimension (longest diameter in the
plane of measurement is to be recorded) with a minimum size of:

10 mm by CT scan (CT scan slice thickness no greater than 5 mm)

10 mm caliper measurement by clinical exam (lesions which cannot be accurately
measured with calipers should be documented as not measurable).

20 mm by chest X-ray.
Malignant lymph nodes: To be considered pathologically enlarged and measurable, a lymph
node must be ≥15 mm in short axis when assessed by CT scan (CT scan slice thickness
recommended to be no greater than 5 mm). At baseline and in follow-up, only the short axis will
be measured and followed.
1.1.2
Not measurable
All other lesions, including small lesions (longest diameter <10 mm or pathological lymph nodes
with a short axis ≥10 and <15 mm) as well as truly not measurable lesions. Lesions considered
truly not measurable include: leptomeningeal disease, ascites, pleural or pericardial effusion,
inflammatory breast disease, lymphangitis involving the skin or lungs, abdominal masses/
abdominal organomegaly identified by physical exam but not measurable by reproducible
imaging techniques.
1.1.3
Special considerations regarding measurable bone lesions, cystic lesions, and lesions
with prior locoregional treatment:
Bone lesions:

Bone scan, PET scan or plain films are not considered adequate imaging
techniques to measure bone lesions. However, these techniques can be used to
confirm the presence or disappearance of bone lesions.


Lytic bone lesions or mixed lytic-blastic lesions, with identifiable soft tissue
components, that can be evaluated by cross sectional imaging techniques (such as
CT or MRI) can be considered as measurable lesions if the soft tissue
components meet the definition of measurability described above.

Blastic bone lesions are not measurable.
Cystic lesions:

Lesions that meet the criteria for radiographically defined simple cysts should not
be considered as malignant lesions (neither measurable nor not measurable) since
they are, by definition, simple cysts.

‘Cystic lesions’ thought to represent cystic metastases can be considered as
measurable lesions, if they meet the definition of measurability described above.
However, if noncystic lesions are present in the same patient, these noncystic
lesions are preferred for selection as target lesions.
Lesions with prior locoregional treatment:

Tumor lesions situated in a previously irradiated area or in an area subjected to
other locoregional therapy are usually not considered measurable, unless there
has been demonstrated progression in the lesion. The study protocol should detail
the conditions under which such lesions would be considered measurable.
1.2
Specifications by Methods of Measurements
1.2.1
Measurement of lesions
All measurements should be documented with metric symbols. Calipers should be used if clinical
assessments are required. All baseline evaluations should be performed as close as possible to
the beginning of the treatment but never more than 4 weeks before the beginning of the treatment.
1.2.2
Method of assessment
The same method of assessment and the same technique should be used to characterize each
identified and reported lesion at baseline and during follow-up. Imaging evaluation should
always be done rather than clinical examination unless the lesion(s) being followed cannot be
imaged but are assessable by clinical examination.
Clinical lesions: Clinical lesions will only be considered measurable when they are superficial
and its diameter is ≥10 mm as assessed using calipers (e.g. skin nodules). For skin lesions,
documentation by color photography including a plotting scale to estimate the size of the lesion
is recommended. As noted above, when lesions can be evaluated by both clinical examination
and imaging evaluation, the latter should be undertaken since it is more objective and may also

be reviewed at the end of the study.
Chest X-ray: Chest CT is preferred over chest X-ray, particularly when progression is an
important endpoint, since CT is more sensitive than X-ray, particularly in identifying new lesions.
However, lesions on chest X-ray may be considered measurable if they have clear boundaries
and are surrounded by aerated lung tissues.
CT and MRI: CT is the best currently available and reproducible method to measure lesions
selected for response assessment. This guideline has defined measurability of lesions on CT scan
based on the assumption that CT slice thickness is 5 mm or less. When CT scans have a slice
thickness greater than 5 mm, the minimum size for a measurable lesion should be twice the slice
thickness. MRI is also acceptable in certain situations (e.g. for body scans).
Ultrasound: Ultrasound should not be used for measuring lesion size and should not be used as
a method of measurement. Ultrasound examinations cannot be reproduced in their entirety for
independent review at a later date and, because they are operator dependent, it cannot be
guaranteed that the same technique and measurements will be taken from one assessment to the
next. If new lesions are identified by ultrasound in the course of the study, confirmation by CT
or MRI is recommended. If there is concern about radiation exposure at CT, MRI may be used
instead of CT in selected instances.
Endoscopy and laparoscopy: The utilization of these techniques is not recommended for
objective tumor evaluation. However, they can be used to confirm complete pathological
response when biopsies are obtained or to determine relapse in trials where recurrence following
complete response or surgical resection is an endpoint.
Tumor markers: Tumor markers alone cannot be used to assess objective tumor response. If
markers are initially above the upper limit of normal, however, they must normalize for a patient
to be considered in complete response. Because tumor markers are disease specific, instructions
for their measurement should be incorporated into the protocol on a disease specific basis.
Specific guidelines for both CA-125 response (in recurrent ovarian cancer) and PSA response
(in recurrent prostate cancer) have been published. In addition, the Gynecologic Cancer
Intergroup has developed CA125 progression criteria which are to be integrated with objective
tumor assessment for use in first-line trials in ovarian cancer.
Cytology and histology: These techniques can be used to differentiate between PR and CR in rare
cases if required by the protocol (for example, residual lesions in tumor types such as seminoma,
where known residual benign tumors can remain). When effusions are known to be a potential
adverse effect of treatment (e.g. with certain taxane compounds or angiogenesis inhibitors),
cytological confirmation of the neoplastic origin of any effusion that appears or worsens during

treatment can be considered if the measurable tumor has met criteria for response or stable
disease in order to differentiate between response (or stable disease) and progressive disease.
2.
TUMOR RESPONSE EVALUATION
2.1
Assessment of Overall Tumor Burden and Measurable Disease
To assess objective response or future progression, it is necessary to estimate the overall tumor
burden at baseline and use this as a comparator for subsequent measurements. Only patients with
measurable disease at baseline should be included in regimens where objective tumor response is
the primary endpoint. Measurable disease is defined by the presence of at least one measurable
lesion. In studies where the primary endpoint is tumor progression (either time to progression or
proportion with progression at a fixed date), the protocol must specify if entry is restricted to
those with measurable disease or whether patients having non-measurable disease only are also
eligible.
2.2
Baseline Documentation of "Target" and "Non-Target" Lesions
When more than one measurable lesion is present at baseline, all lesions (five lesions at most,
and two lesions per organ at most) representative of all involved organs should be identified as
target lesions and will be recorded and measured at baseline (This means in instances where
patients have only one or two organ sites involved, a maximum of two and four lesions
respectively will be recorded).
Target lesions should be selected on the basis of their size (lesions with the longest diameter), be
representative of all involved organs, and should be those with reproducible repeated
measurements. It may be the case that, the largest lesion does not have reproducible
measurements, in which circumstance the next largest lesion with reproducible measurements
should be selected.
Lymph nodes merit special mention since their normal anatomical structures may be visible by
imaging even if not involved by tumor. Pathological nodes which are defined as measurable and
may be identified as target lesions must have a short axis of ≥15 mm by CT scan. Only the short
axis of these nodes will contribute to the baseline sum. The short axis of the node is the diameter
normally used by radiologists to judge if a node is invaded by solid tumor. Nodal size is
normally reported as two dimensions in the plane in which the image is obtained (for CT scan
this is almost always the axial plane; for MRI the plane of acquisition may be axial, sagittal or
coronal). The smaller of these measures is the short axis. For example, an abdominal node which
is reported as being 20 mm × 30 mm has a short axis of 20 mm and qualifies as a malignant
measurable node. In this example, 20 mm should be reported as the node measurement. All other
pathological nodes (those with a short axis ≥10 mm but < 15 mm) should be considered non-

target lesions. Lymph nodes that have a short axis < 10 mm are considered non-pathological and
should not be recorded or followed.
A sum of the diameters (longest for non-nodal lesions; short axis for nodal lesions) for all target
lesions will be calculated and reported as the baseline sum of diameters. If lymph nodes are to be
included in the sum, then as noted above, only the short axis is added into the sum. The baseline
sum of diameters will be used as reference to further characterize any objective tumor regression
in the measurable dimension of the disease.
All other lesions (or sites of disease) including pathological lymph nodes should be identified as
non-target lesions and should also be recorded at baseline. Measurements are not required and
these lesions should be recorded as "present", "absent", or in rare cases "unequivocal
progression". In addition, it is possible to record multiple target lesions involving the same organ
as a single item on the case record form (e.g. ‘multiple enlarged pelvic lymph nodes’ or ‘multiple
liver metastases’).
2.3
Response Criteria
2.3.1
Evaluation of target lesions
Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes
(whether target or non-target) must have a reduced short axis of <10 mm.
Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions vs. the
baseline sum of diameters.
Progressive Disease (PD): At least a 20% increase in the sum of diameters of target lesions vs.
the smallest sum during the study (this includes the baseline sum if that is the smallest). In
addition to the relative increase of 20%, the sum must also have an absolute increase of at least
5 mm. (Note: The appearance of one or more new lesions is also considered progression).
Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to
qualify for PD, using the smallest sum of diameters during the study as reference.
2.3.2
Special notes on the assessment of lymph nodes which are target lesions
Lymph nodes identified as target lesions should always have the actual short axis measurement
recorded (measured in the same anatomical plane as during the baseline examination), even if the
nodes regress to below 10 mm at the time of the study. This means that when lymph nodes are
included as target lesions, the "sum" of lesions may not be zero even if complete response
criteria are met, since a normal lymph node is defined as having a short axis of <10 mm. Case
report forms or other data collection methods may therefore be designed to have target nodal
lesions recorded in a separate section where, in order to qualify for CR, each node must have a

short axis of <10 mm. For PR, SD, and PD, the actual short axis measurement of the nodes is to
be included in the sum of target lesions.
Target lesions that are "too small to measure". During the study, all lesions (nodal and non-
nodal) recorded at baseline should have their actual measurements recorded at each subsequent
evaluation, even when very small (e.g. 2 mm). However, sometimes lesions or lymph nodes
which are recorded as target lesions at baseline become so faint on CT scan that the radiologist
may not feel comfortable assigning an exact measurement and may report them as being "too
small to measure". When this occurs it is important that a value be recorded on the case report
form. If it is the opinion of the radiologist that the lesion has probably disappeared, the
measurement should be recorded as 0 mm. If the lesion is believed to be present and is faintly
seen but too small to measure, a default value of 5 mm should be assigned (Note: It is less likely
that this rule will be used for lymph nodes since they usually have a definable size when normal
and are frequently surrounded by fat such as in the retroperitoneum; however, if a lymph node is
believed to be present and is faintly seen but too small to measure, a default value of 5 mm
should be assigned in this circumstance as well). This default value is derived from the 5 mm CT
slice thickness (but should not be changed with varying CT slice thickness). The measurements
of these lesions are potentially non-reproducible, therefore providing this default value will
prevent false responses or progressions caused by measurement errors. To reiterate, however, if
the radiologist is able to provide an actual measurement, that value should be recorded, even if it
is below 5 mm.
Lesions that split or coalesced at the time of treatment. When non-nodal lesions fragment, the
longest diameters of the fragmented portions should be added together to calculate the target lesion sum.
Similarly, as lesions coalesce, a plane between them may be maintained that would aid in obtaining
maximal diameter measurements of each individual lesion. If the lesions have truly coalesced such that
they are no longer separable, the vector of the longest diameter in this instance should be the maximal
longest diameter for the "coalesced lesion".
2.3.3
Evaluation of non-target lesions
This section provides the definitions of the criteria used to determine the tumor response for the
group of non-target lesions. While some non-target lesions may actually be measurable, they do
not need to be measured and instead should be assessed only qualitatively at the time points
specified in the protocol.
Complete Response (CR): Disappearance of all non-target lesions and normalization of tumor
marker level. All lymph nodes must be non-pathological in size (short axis <10 mm).
Non-CR/Non-PD: Persistence of one or more non-target lesion(s) and/or maintenance of tumor
marker level above the normal limits.

Progressive Disease (PD): Unequivocal progression of existing non-target lesions. (Note: The
appearance of one or more new lesions is also considered progression).
2.3.4
Special notes on the assessment of progression of non-target lesions
The concept of progression of non-target disease requires additional explanation as follows: When
the patient also has measurable lesions. In this setting, to achieve ‘unequivocal progression’ on the
basis of the non-target lesion, there must be an overall level of substantial worsening in non-target
disease such that, even in the presence of SD or PR of the target disease, the overall tumor burden
has increased sufficiently to merit discontinuation of therapy. A minimal increase in the size of one
or more non-target lesions is usually not sufficient to quality for unequivocal progression status.
The designation of overall progression solely on the basis of change in non-target lesions in the
face of SD or PR of target disease will therefore be extremely rare.
When the patient has only lesions that are not measurable. This circumstance arises in some
phase III trials when the presence of measurable lesions is not a criterion for study enrollment.
The same general concepts apply here as well. However, in this instance there are no measurable
lesions to factor into the interpretation of an increase in non-measurable lesion burden. Because
worsening in non-target lesion cannot be easily quantified (by definition: if all lesions are truly
not measurable), a useful test that can be applied when assessing patients for unequivocal
progression is to consider if the increase in overall lesion burden based on the change in non-
measurable disease is comparable in magnitude to the increase that would be required to declare
PD for measurable disease: i.e. an increase in tumor burden representing an additional 73%
increase in volume (which is equivalent to a 20% increase of diameter in a measurable lesion).
Examples include an increase in pleural effusion from "trace" to "large amount", an increase in
lymphangitic lesion from localized to widespread, or a description in the protocol such as
"sufficient to require a change in therapy". If ‘unequivocal progression’ is seen, the patient
should be considered to have had overall PD at that point. While it would be ideal to have
objective criteria to apply to diseases that are not measurable, the very nature of these diseases
makes it impossible to do so, therefore the increase must be substantial.
2.3.5
New lesions
The appearance of new malignant lesions denotes disease progression; therefore, some
comments on the detection of new lesions are important. There are no specific criteria for the
identification of new radiographic lesions; however, the finding of a new lesion should be
unequivocal: i.e. not attributable to differences in scanning technique, change in imaging
modality or findings thought to represent something other than tumors (for example, some new
bone lesions which may be simply healed or flare of pre-existing lesions). This is particularly

299/560

Confidential
important when the patient’s baseline lesions show partial or complete response. For example,
necrosis of a liver lesion may be reported by a CT scan as a "new" cystic lesion, while it is
actually not.
A lesion identified during a follow-up in an anatomical location that is not discovered during the
baseline scan is considered a new lesion and will indicate disease progression. For example, a
patient with a visceral disease at baseline has a brain CT or MRI which reveals metastases. The
patient's brain metastases are considered evidence of PD even if he/she does not have brain
imaging at baseline.
If a new lesion is equivocal, for example because of its small size, continued therapy and follow-
up evaluation will clarify if it represents a truly new lesion. If repeat scans confirm there is
definitely a new lesion, then progression should be declared using the date of the initial scan.
While FDG-PET response assessments need additional studies, it is sometimes reasonable to
incorporate the use of FDG-PET scanning to complement CT scanning in assessment of
progression (particularly possible "new" lesions). New lesions on the basis of FDG-PET imaging
can be identified as follows:
a.
A negative FDG-PET at baseline and a positive FDG-PET at follow-up is a sign of PD
based on a new lesion.
b.
No FDG-PET at baseline and a positive FDG-PET at follow-up:
If the positive FDG-PET at follow-up corresponds to a new lesion site confirmed by
CT, this is PD. If the positive FDG-PET at follow-up is not confirmed as a new lesion
site on CT, additional follow-up CT scans are needed to determine if there is truly
progression at that site (if so, the date of PD will be the date of the initial abnormal
FDG-PET scan). If the positive FDG-PET at follow-up corresponds to a pre-existing
lesion site on CT that is not progressing according to the anatomic images, this is not PD.
2.4
Evaluation of Best Overall Response
The best overall response is the best response recorded from the start of the study treatment until
the end of treatment, taking into account any requirement for confirmation. On occasion a
response may not be documented until after the end of therapy, so the study protocol should
clearly state if post-treatment assessments are to be considered when determining best overall
response. The study protocol must specify how any new therapy introduced before progression
will affect best response designation. Assignment of best overall response for the patient will
depend on the findings of both target and non-target lesions and will also take into consideration
the appearance of new lesions. Furthermore, depending on the nature of the study and the

protocol requirements, confirmatory measurement may also be required. Specifically, in non-
randomized trials where response is the primary endpoint, confirmation of PR or CR is needed to
determine which one is the "best overall response".
2.4.1
Time point response
It is assumed that at each time point specified by the study protocol, a response assessment
occurs. Table 1 on the next page provides a summary of the overall response status calculation at
each time point for patients who have measurable disease at baseline.
When patients have non-measurable (therefore non-target) disease only, Table 2 is to be used.
2.4.2
Missing assessments and non-evaluable targets
When no imaging/measurement is done at a particular time point, the patient is not evaluable
(NE) at that time point. If only a subset of lesion measurements is made at an assessment, usually
the case is also considered NE at that time point, unless a convincing argument can be made that
the missing lesion(s) would not change the response at the assigned time point. This would be
most likely to happen in the case of PD. For example, if a patient has a baseline sum of 50 mm
with three measured lesions and at follow-up only two lesions are assessed and with a sum of 80
mm, the patient will have achieved PD status, regardless of the contribution of the missing lesion.
2.4.3
Best overall response: all time points
The best response is determined once all the data for the patient is obtained.
Best response determination in trials where confirmation of complete or partial response is not
required: Best response in these trials is defined as the best response across all time points (for
example, the best overall response of a patient who has SD at the first assessment, PR at the
second, and PD at the last is PR). When SD is believed to be best response, it must also meet the
minimum time from baseline specified by the protocol. If the minimum time is not met,
otherwise SD is the best time point response, the patient’s best response depends on subsequent
assessments. For example, if a patient has SD at the first assessment, PD at the second and does
not meet the minimum duration for SD, his/her best response is PD. The same patient lost to
follow-up after the first SD assessment would be considered not evaluable.
Best response determination in trials where confirmation of complete or partial response is
required: Complete or partial responses may be claimed only if the criteria for each are met at a
subsequent time point specified in the protocol (generally 4 weeks later). In this circumstance,
the best overall response can be interpreted as in Table 3.

2.4.4
Special notes on response assessment
When nodal lesions are included in the sum of target lesions and the nodes decrease to "normal"
size (<10 mm), they may still have a measurement reported on scans. This measurement should
be recorded even if the nodes are normal in size in order not to overstate progression should it be
based on the increase in size of the nodes. As noted earlier, this means that patients with CR may
not have a total sum of "zero" on the case report form (CRF).
In trials where confirmation of response is required, repeated "NE" time point assessments may
complicate best response determination. The analysis plan for the trial must explain how missing
data/assessments will be addressed in the determination of response and progression. For
example, in most trials it is reasonable to consider a patient with time point responses of PR-NE-
PR as a confirmed response.
Patients with a global deterioration of health status requiring discontinuation of treatment without
objective evidence of disease progression at that time should be reported as "symptomatic
deterioration". Every effort should be made to document objective progression even after
discontinuation of treatment. Symptomatic deterioration is not a descriptor of an objective
response. Instead, it is a reason for stopping the study treatment. The objective response status of
this type of patients is to be determined by evaluation of target and non-target lesions as shown
in Table 1–3.
Conditions that define "early progression, early death, and non-evaluability" are study specific
and should be clearly described in each study protocol (depending on treatment duration and
treatment periodicity).
In some circumstances it may be difficult to distinguish a residual lesion from normal tissues.
When the evaluation of complete response depends upon this determination, it is recommended
that the residual lesion be investigated (by fine needle aspirate/biopsy) before assigning a status
of complete response.
Like a biopsy, FDG-PET may also be used to upgrade a response to a CR in cases where a
residual radiographic abnormality is thought to represent fibrosis or scarring. The use of FDG-
PET in this circumstance should be pre-defined in the protocol and supported by disease specific
medical literature for the indication. However, it must be acknowledged that both approaches
may lead to false positive CR due to limitations of FDG-PET and biopsy resolution/sensitivity.

a "Non-CR/non-PD" is preferred over "stable disease" for non-target disease, since SD is increasingly used as an
endpoint for assessment of efficacy in some trials, thus assigning this category in the absence of measurable
lesions is not advised.
For equivocal findings of progression (e.g. very small and uncertain new lesions; cystic changes
or necrosis in existing lesions), treatment may continue until the next scheduled assessment. If at
the next scheduled assessment, progression is confirmed, the date of progression should be the
earlier date when progression is suspected.

a If CR is truly achieved at the first time point, then any lesions seen at a subsequent time point, even those meeting
PR criteria relative to baseline, make the disease PD at that time point (since lesions must have reappeared after
CR). Best response would depend on whether the minimum duration for SD is met. However, sometimes CR may
be claimed and subsequent scans suggest small lesions are likely still present, while in fact the patient have PR
instead of CR at the first time point. Under these circumstances, CR should be changed to PR and the best response
is PR.
2.5 Frequency of Tumor Re-Evaluation
Frequency of tumor re-evaluation during treatment should be protocol specific and adapted to the
type and schedule of treatment. However, for phase II studies where the beneficial effect of the
treatment is not known, follow-up every 6–8 weeks (timed to coincide with the end of a cycle) is
reasonable. Smaller or greater time intervals may be justified for certain regimens or circumstances.
The study protocol should specify which organ sites are to be evaluated at baseline (usually those
most likely to be involved with metastatic disease for the tumor type under study) and how
often evaluations are repeated. Normally, all target and non-target sites are evaluated at each
assessment. Under certain circumstances, some non-target organs may be evaluated less frequently.
For example, bone scans may need to be repeated only when complete response is identified in
the target lesion or when progression is suspected.

After the end of the treatment, the need for repeated tumor evaluations depends on whether the
trial has a goal such as a certain response rate or a certain time to an event (progression/death).
If ‘time to an event’ (e.g. time to progression, disease-free survival, progression-free survival) is
the main endpoint of the study, then routine scheduled re-evaluation of lesion sites specified by
the protocol must be carried out. In randomized comparative trials in particular, the scheduled
assessments should be performed on time (for example: every 6–8 weeks during the treatment or
every 3–4 months after the treatment) and should not be affected by treatment delays, holidays or
any other events that might lead to imbalance in the timing of disease assessment between
treatment arms.
2.6 Confirmation of Measurements/Duration of Response
2.6.1 Confirmation
In non-randomized trials where response is the primary endpoint, confirmation of PR and CR is
required to ensure responses identified are not the result of measurement errors. This will also
permit appropriate interpretation of results in the context of historical data. Response
confirmation has been traditionally required in such trials. However, in all other circumstances,
i.e. in randomized trials (phase II or III) or studies where stable disease or progression are the
primary endpoints, confirmation of response is not required since it will not add value to the
interpretation of trial results. However, elimination of the requirement for response confirmation
may increase the importance of central review to protect against bias, in particular in studies
which are not blinded.
In the case of SD, measurements after study entry must have met the minimum interval for SD
(generally not shorter than 6–8 weeks) defined in the study protocol at least once.
2.6.2 Duration of overall response
The duration of overall response is measured from the time CR/PR measurement criteria are first
met CR/PR (whichever is first documented) until the date when recurrent or progressive disease
is objectively documented for the first time (using the shortest time to progressive disease
documented during the study as reference).
The duration of overall complete response is measured from the time CR measurement criteria
are first met until the date when recurrent disease is objectively documented for the first time.
2.6.3 Duration of stable disease
Stable disease is measured from the start of the treatment (in randomized trials, from the date
of randomization) until the criteria for progression are met, using the smallest sum during the
study as reference (if the baseline sum is the smallest, then it is used as the reference for the
calculation of PD).

The clinical relevance of the duration of stable disease varies with different studies and diseases.
If the proportion of patients achieving stable disease for a minimum period of time is an endpoint
of importance in a particular trial, the protocol should specify the minimal time interval required
between two measurements for the determination of stable disease.
Note: The duration of response and stable disease as well as the progression-free survival are
influenced by the frequency of follow-up after baseline evaluation. It is not in the scope of the
guidelines to define a standard follow-up frequency. The frequency should take into account
many parameters including disease types and stages, treatment periodicity, and standard practice.
However, limitations of the precision of the measured endpoint should be taken into account if
comparisons between trials are to be made.

However, surgical operations cannot be carried out for almost all
stage IV patients with a clear diagnosis, most stage IIIB patients, and

Judged by the investigator as clinically significant
It is the responsibility of the investigator to review all abnormal
laboratory test results and vital signs, and to determine whether each
abnormal laboratory test result or vital signs should be reported as
AEs.
If clinically significant laboratory abnormalities or abnormal vital
signs are characteristic of a disease or syndrome (such as increased
levels of alkaline phosphatase and total bilirubin caused by
cholecystitis that are higher than 5 times the upper limit of normal),
All clinically significant laboratory test abnormalities should be
reported as AEs. It is the responsibility of the investigator to review
all abnormal laboratory test results, and to make medical judgments
as whether each abnormal laboratory test result should be reported
as an AE.

only the diagnosis is recorded on the AE report of the eCRF (i.e.,
cholecystitis). Conversely, the laboratory abnormalities or abnormal
vital signs are recorded on the AE report of the eCRF, and it should
be indicated that whether the test value is above or below the
normal range (for example, it should be recorded as "blood
potassium increased" instead of "blood potassium abnormal"). If
there is a standard clinical term corresponding to the laboratory
abnormalities or abnormal vital signs, the clinical term should be
recorded on the eCRF (such as "anemia", instead of "hemoglobin
decreased"). The same clinically significant laboratory
abnormalities or abnormal vital signs found during multiple follow-
ups should not be repeatedly recorded as AEs or SAEs in the eCRF
unless there is a change in its severity or etiology.

within 90 days after the last dose were documented in the Death
Report Form in the eCRFs and reported to the sponsor timely,
regardless of the causality with the investigational drug.

Progressive disease
A progressive disease is defined as the worsening of subject
condition caused by the primary tumor that the investigational drug
is targeting, the appearance of new lesions, or the progression of the
primary lesion. Expected progressive disease should not be reported
as an AE. Any deaths, life-threatening events, hospitalization or

Phase: III
Study Objectives:
Primary Objective:

To compare the objective response rate (ORR) of IBI305 plus paclitaxel/carboplatin versus bevacizumab
plus paclitaxel/carboplatin for the treatment of advanced or relapsed non-squamous non-small cell lung
cancer (NSCLC)
Secondary Objectives:

To compare the duration of response (DOR), progression-free survival (PFS), disease control rate (DCR),
and overall survival (OS) of IBI305 plus paclitaxel/carboplatin versus bevacizumab plus
paclitaxel/carboplatin for the treatment of advanced or relapsed non-squamous NSCLC

To compare the safety and immunogenicity of IBI305 plus paclitaxel/carboplatin versus bevacizumab
plus paclitaxel/carboplatin for the treatment of advanced or relapsed non-squamous NSCLC
Exploratory objectives:

advanced or recurrent non-squamous NSCLC

To compare the PD of IBI305 and bevacizumab in subjects with advanced or recurrent non-squamous
NSCLC
Study design:
This is a randomized, double-blinded, multi-center phase III study. The study planned to enroll and randomize 436
subjects with non-squamous NSCLC in a 1:1 ratio to IBI305 plus paclitaxel/carboplatin group or bevacizumab plus
paclitaxel/carboplatin group. Stratifying factors include age (< 60 vs. ≥60 years old) and EGFR status (wild type vs.
unknown type).
Each treatment cycle is 3 weeks for both groups. 15 mg/kg IBI305 or bevacizumab is administered on D1 of each
cycle along with paclitaxel/carboplatin. Subjects will receive up to 6 treatment cycles of combination therapy until
PD, unacceptable toxicity, withdrawal of informed consent, loss to follow-up, or death (whichever comes first).
Then subjects receive maintenance monotherapy, that is, discontinuing paclitaxel/carboplatin while continuing
therapy with IBI305 or bevacizumab. The maintenance monotherapy continues every 3 weeks. On D1 of each
treatment cycle, subjects will be administered 7.5 mg/kg of either IBI305 or bevacizumab until PD, unacceptable
toxicity, withdrawal of informed consent, loss to follow-up, death, or end of study (whichever comes first).
During the study, a CT or an MRI will be performed every 6 weeks (± 7 days) and be determined whether the study
treatment will be continued by investigators at each site through tumor assessments until PD, withdrawal of
informed consent, lost to follow-up, death, start of other anti-tumor therapies, or end of study. If subjects discontinue
the study treatment for reasons other than PD, tumor assessments will be continued until PD, withdrawal of
informed consent, loss of follow-up, death, start of other anti-tumor therapies, or end of study. If subjects discontinue
the study treatment for PD, the investigators will make telephone follow-up every 12 weeks (± 7 days) to collect
information of subsequent anti-tumor therapies and survival until withdrawal of informed consent, lost to follow-up,
death, or end of study.

Statistical methods:
Sample size calculation:
A number of 218 subjects for each group (436 subjects in total) can provide 80% test power to confirm the clinical
equivalence between the treatments of IBI305 in combination with paclitaxel/carboplatin and bevacizumab in combination
with paclitaxel/carboplatin. Estimation parameters for sample size: The significance level of the two-sided test is 0.05, the
ORR of subjects in the IBI305 and bevacizumab groups is about 50.0%, and the equivalence margin is taken as (-12.5%,
16.7%). Based on the above hypothesis, each group requires 218 subjects (436 subjects in total).
Efficacy analysis:
Clinical equivalence will be determined by whether the 90% confidence interval (CI) of the difference in ORR
between the IBI305 and bevacizumab arms falls within the preset margin of (-12.5%, 16.7%). The ORR and 95% CI
of two groups, ORR difference and 90% CI, and ORR ratio and 90% CI will be estimated using the generalized

linear model (GLM, including groups and stratification factors).
Median survival (OS) and survival curves will be estimated using the Kaplan-Meier method. The hazard ratio (HR)
and 95% CI of two groups will be estimated using the Cox model. DORs and PFSs will be analyzed by the same
method as the median survivals. DCR will be analyzed using the same method for primary efficacy endpoints, but
an equivalence test will not be conducted.
Safety analysis:
All adverse events (AE) will be coded using MedDRA and graded according to CTCAE v4.03. All treatment-
emergent adverse events (TEAEs), Grade 3 or greater TEAEs, serious adverse events (SAEs), investigational drug-
related TEAEs, investigational drug-related SAEs, TEAEs leading to treatment discontinuation, TEAEs leading
to study termination, and adverse events of special interest (AESIs) will be listed based on system organ class,
preferred terms, and groups and the numbers of corresponding subjects and percentages will be summarized.
In addition, the severity of TEAEs and the correlation with the study drug will also be summarized by system
organ class, preferred terms, and treatment groups.
Measured values and changes from baseline for vital signs, physical examination, laboratory tests and 12-lead ECG
will be analyzed using descriptive statistics. Baseline results and worst results during the study will be presented in
cross tabulation.
The number and percentage of subjects who developed anti-drug antibodies and neutralizing antibodies during the
study will be summarized by treatment group.
PK/PD exploratory analysis:
Mainly based on description, and inter-group comparison will be carried out if necessary

a.
After completing the on-site end-of-treatment visit 28 days after the last dose, subjects who discontinue the
investigational drug treatment due to reasons other than PD should continue to undergo tumor assessments once
every 6 weeks (±7 days) until PD (and begin post-PD follow-up thereafter), withdrawal of consent, start of another
antineoplastic treatment, loss to follow-up, death, or study completion.
b.
For subjects with PD, collect survival information once every 12 weeks (84 days, ±7 days) by phone until death,
loss to follow-up, withdrawal of informed consent, or study completion. Subsequent antineoplastic treatments
should be documented in the eCRF.
c.
Only measure weight.
d.
Clinical laboratory tests are carried out at the laboratory of each hospital. If screening laboratory tests (routine
blood test, blood chemistry, and urinalysis) are performed within 7 days prior to the first dose, the screening
results may be used as baseline data. For subsequent visits, all laboratory tests have to be completed within 3
days prior to the dose administration.
e.
Prior to each IBI305/bevacizumab infusion, test paper should be used to examine urinary protein.
f.
Women of childbearing age should undergo serum pregnancy tests.
g.
Immunogenicity tests will be performed in all subjects at 3 blood sampling time points: Within 1 hour prior to
the first dose of the study treatment (IBI305/bevacizumab) in C1, within 1 hour prior to the administration of
the study treatment in C4, and during the end-of-treatment visit. Blood specimens that are positive for anti-drug
antibodies (ADA) after dosing will be further tested for neutralizing antibodies (NAb). Samples will be tested
at the designated central laboratory.
h.
Image assessments (CT or MRI) of the brain, chest, abdomen, and pelvis should be completed at baseline. If
these tests are performed within 28 days prior to the first dose of the study drug, they do not need to be repeated
unless the investigator believes that there have been changes in the subject's tumor burden. After the start of
treatment, imaging tests are performed once every 6 weeks (±7 days) and have to be completed within 7 days
prior to the scheduled visits, until progressive disease, start of other treatment, withdrawal of informed consent,
loss to follow-up, death, or study completion. The same method of imaging test is used at baseline and during
follow-up. Imaging evaluations of the chest, abdomen, and pelvis are required.
i.
All subjects should undergo tumor tissue EGFR testing, but the test does not need to be repeated if it can be
confirmed with relevant reports that the test has already been completed at the trial site. EGFR testing will be
carried out at the laboratory of each trial site.

j.
Each treatment cycle for the investigational drug is 3 weeks long. IBI305 or bevacizumab is administered on
D1 of each cycle, at 15 mg/kg during combination treatment with chemotherapy and 7.5 mg/kg during
monotherapy, until disease progression (PD), unacceptable toxicity, withdrawal of informed consent, loss to
follow-up, death, or study completion, whichever occurs first. After all assessments are completed, the study
drug is administered followed by chemotherapy. After all assessments are completed, the study drug is
administered followed by chemotherapy.
k.
Each treatment cycle is 3 weeks long. Chemotherapy (paclitaxel + carboplatin) is administered on D1 of each
cycle for up to 6 cycles, or until disease progression (PD), unacceptable toxicity, withdrawal of informed
consent, loss to follow-up, or death. Paclitaxel is administered after the infusion of study drug is completed,
followed by carboplatin.
l.
Study sites that are implementing version 2.0 of the study protocol should collect PK samples until 140 subjects
in this study meet the requirements for PPK assessment (based on the written notice of the sponsor). There are
6 PK sampling time points: Within 1 h before the first dose of the study drug (IBI305/bevacizumab) in C1,
immediately after the first infusion (within 5 minutes), within 1 h prior to the dose in C2, within 1 h prior to the
dose in C4, within 1 hour prior to the dose in C5, and within 1 h prior to the dose in C6. Serum will be
separated from the samples at the study site and the serum samples will be analyzed at the designated central
laboratory.
m.
Study sites that are implementing version 2.0 of the study protocol should collect PD samples until 140 subjects
in this study meet the requirements for VEGF testing (based on the written notice of the sponsor). There are 4
VEGF sampling time points: Within 1 h prior to the first dose of the study drug (IBI305/bevacizumab) in C1,
within 1 h prior to the dose in C2, within 1 h prior to the dose in C6, and at the end of treatment visit. Samples
were tested at the designated central laboratory.

1 INTRODUCTION
1.1 Study Background
1.1.1 Disease background
Lung cancer has the highest incidence and mortality globally among all cancers. According to the
2012 Global Cancer Statistics (GLOBOCAN 2012) published by International Agency for
Research on Cancer, there were approximately 1.8 million new lung cancer cases worldwide,
which accounted for 13% of the global newly-diagnosed cancers, and 58% of these cases occurred
in underdeveloped areas1. According to the data released by the National Central Cancer Registry
of China in 2015, lung cancer was the most prevalent malignancy in China in 2011, with about
650,000 new cases every year. Lung cancer was also the leading cause of death, with about
520,000 deaths per year2. The limited clinical treatment of lung cancer is the main reason for its
poor prognosis. There is a huge demand for new types of lung cancer treatment drugs.
Approximately 85–90% of lung cancers are non-small cell lung cancer (NSCLC) and patients
with NSCLC are usually in the advanced stages when diagnosed3. According to the Chinese
guidelines for the diagnosis and treatment of primary lung cancer, anatomic pulmonary resection
is the mainstay of treatment for early stage lung cancers4. However, despite surgery, some
patients develop distance metastases that eventually lead to death5. Surgery is not possible for
most patients with clearly diagnosed stage IIIb and IV as well as some patients with stage IIIa
NSCLC4. Comprehensive treatment based on systemic therapy is used to maximize patient
survival, control progressive disease, and improve the quality of life6.
In recent years, anti-tumor therapies have entered a new era with the emergency of targeted
drugs. Some of these targeted drugs have demonstrated satisfactory efficacy in the treatment of
advanced NSCLC. These targeted drugs include monoclonal antibodies and tyrosine kinase
inhibitors (TKIs), mostly targeting epidermal growth factor receptors (EGFRs) and vascular
endothelial growth factor (VEGF), such as bevacizumab, cetuximab, gefitinib, erlotinib, and
icotinib. Monoclonal antibodies have become the drugs of choice in various treatment guidelines
due to the good targeting ability, low drug resistance, and good patient tolerability. Bevacizumab
combination chemotherapy is a first-line therapy of NSCLC recommended by the National
Comprehensive Cancer Network (NCCN)7. Additionally, bevacizumab in combination with
paclitaxel/carboplatin has also been approved as the first-line therapy of unresectable advanced,
metastatic, or relapsed non-squamous NSCLC by China Food and Drug Administration (CFDA)
on Jul. 9, 20156.

Compared with traditional chemotherapy that directly inhibit or kill tumor cells, anti-angiogenic
drugs have the following unique advantages8:

The targets are genetically stable vascular endothelial cells (VECs) rather than highly
heterogeneous tumor cells, thus leading to lower drug resistance;

The number of tumor-induced VECs is far less than that of tumor cells, and the efficacy
is preferable targeting on VECs and their cytokines;

Normal VECs are quiescent, whereas tumor VECs are active in proliferation. Anti-
angiogenic therapy targets activated cells and avoids damage to normal VECs, thus
leading to better targeting ability;

Anti-angiogenic therapy can normalize the tumor vessels and thereby reduce the
pressure in tumor tissues. This enhances the delivery of chemotherapeutic agents into
tumor tissues, thus increasing the efficacy of chemotherapy.
Angiogenesis is a basic biological characteristic of tumors. The growth of both solid and
hematologic tumors are depended on angiogenesis regardless of the nature of tumor cells.
Therefore, anti-angiogenic therapy is broad-spectrum and applicable to various tumors.
Bevacizumab is a recombinant humanized monoclonal antibody that selectively binds to human
VEGF and blocks its biological activity. Bevacizumab consists of a framework region of a
human antibody and a humanized murine antigen binding region that can inhibit the binding of
VEGF to its receptors on epithelial cells, Flt-1 and KDR. By blocking the activity of VEGF and
reducing tumor angiogenesis, tumor growth is inhibited9.
In a study conducted by the Estern Cooperative Oncology Group (ECOG), compared with
chemotherapy alone (paclitaxel/ carboplatin), bevacizumab in combination with paclitaxel/carboplatin
significantly increased the overall survival (OS) (median: 12.3 vs. 10.3 months), progression-free
survival (PFS) (median: 6.2 vs. 4.5 months), and overall response rate (ORR) (35% vs. 15%) in
patients with advanced, metastatic, or relapsed non-squamous NSCLC10. In another foreign
AVAiL study, different doses of bevacizumab (7 and 15 mg/kg) in combination with
chemotherapy (cisplatin and gemcitabine) and placebo combine with chemotherapy were
compared for the treatment of non-squamous NSCLC. The study found that the two
bevacizumab groups had significantly increased the PFS (median: 6.7 months (7.5 mg/kg
combination chemotherapy group) vs. 6.5 months (15 mg/kg combination chemotherapy group)
vs. 6.1 months (placebo combination chemotherapy group)) and the ORR (37.8% (7.5 mg/kg
combination chemotherapy group) vs. 34.6% (15 mg/kg combination chemotherapy group) vs.
21.6% (placebo combination chemotherapy group)) in patients with locally advanced, metastatic,
or relapsed non-squamous NSCLC11. In a BEYOND study conducted in China, compared with

placebo in combination with paclitaxel/carboplatin, bevacizumab in combination with
paclitaxel/carboplatin significantly increase the PFS (median: 9.2 vs. 6.5 months), OS (median:
24.3 vs. 17.7 months), and the ORR (54% vs. 26%) in patients with advanced or relapsed non-
squamous NSCLC12.
In China, the antibodies and fusion proteins targeting VEGF are research hotspots. However,
since 2006, the clinical efficacies of various drugs have not been verified and no products have
been marketed. Considering the complexity of macromolecular drugs and the limitations of drug
development capability in China, advanced technologies in antibody development, production,
and quality control is required to develop high-quality VEGF inhibitors that are safe and
effective. IBI305 has showed high similarity to bevacizumab in various pharmaceutical and
nonclinical studies (refer to Investigator's Brochure [IB]). Besides, the efficacy and safety of
bevacizumab for treatment of locally advanced, metastatic or relapsed lung cancer have been
verified. The relevant domestic and external pivotal clinical studies are referable for the protocol
design of IBI305 clinical study. In summary, the clinical study of IBI305 for treatment of
NSCLC has a solid foundation and relatively low risks. The successful development of IBI305
indicates an additional first-line targeted drug for lung cancer in China, providing doctors and
patients with more therapeutic options.
1.1.2 Investigational drug
1.1.2.1 Description of investigational drug
IBI305 is a recombinant humanized anti-VEGF monoclonal antibody injection developed by
Innovent Biologics (Suzhou) Co., Ltd. (hereafter as sponsor) that specifically binds human
VEGF. The molecular weight of IBI305 is 149 KDa. IBI305 specifically binds to VEGF-A,
inhibits the binding of VEGF-A to VEGF-R1 and VEGF-R2, blocks the signaling pathways such
as PI3K/Akt/PKB and Ras-Raf-MEK-ERK. IBI305 also inhibits the growth, proliferation, and
migration of VECs and angiogenesis, decreases the vascular permeability, blocks blood supply to
tumor tissues, inhibits the proliferation and metastasis of tumor cells, and induces the apoptosis
of tumor cells, thereby generates anti-tumor effects. The main active ingredient is recombinant
humanized anti-VEGF monoclonal antibody and excipients include sodium acetate, sorbitol, and
polysorbate 8013. Refer to the Investigator's Brochure for the detailed structure and
physicochemical properties of IBI305.

1.1.2.2 Preclinical studies
Pharmaceutical studies
The pharmaceutical studies showed that stability, primary structure, higher-order structure,
oligosaccharide distribution, charge variant, and product-related impurities of IBI305 are highly
similar to those of bevacizumab, and the process-related impurities meet the proposed
specification. Therefore, IBI305 is considered to have highly similar protein properties and
product quality to bevacizumab13.
Pharmacodynamic studies
In vitro and in vivo pharmacodynamic (PD) studies of IBI305 showed the following findings:
1)
Target: IBI305 displayed specifically high-affinity binding to recombinant human
VEGF-A with an affinity constant same as that of bevacizumab, indicating that IBI305,
the same as bevacizumab, is a specific human VEGF blocker with a clear target.
2)
Specificity: IBI305 displayed specifically high-affinity binding to recombinant human
VEGF-A, medium-affinity binding to canine VEGF-A, but low-affinity binding to
human VEGF-B, VEGF-C, VEGF-D, PlGF, suggesting that IBI305 recognizes specific
targets and has low off-target toxicity risk; no obvious affinity to mouse VEGF-A164
and rat VEGF-A164, suggesting that IBI305 has high species specificity.
3)
Mechanism of action: IBI305 specifically binds to VEGF-A and inhibits the activation
of VEGFR-2 and ERK1/2, blocks the proliferation and migration of HUVEC, and
inhibits the sprouting from rat aortic ring, suggesting that IBI305 antagonizes VEGF-
A-induced signaling pathway to block the proliferation and migration of VECs and
inhibit angiogenesis, which leads to the reduction of nutritional supply and metastasis
of tumor.
4)
Anti-tumor effects: IBI305 significantly inhibits the growth of human colon cancer
Ls174t and lung cancer NCI-H460 cells in xenografts in nude mice, indicating that
IBI305 has significant anti-tumor effects.
Results from in vitro and in vivo studies of IBI305 showed highly similarity with that of
bevacizumab designed simultaneously, demonstrating that the target, mechanism of action,
and anti-tumor effects of IBI305 are highly similar to bevacizumab13.

Pharmacokinetic studies
In vitro and in vivo pharmacokinetic (PK) studies of IBI305 showed the following findings:
1)
IBI305 showed no significant cross-reactivity with normal human tissues and
cynomolgus monkey tissues, and only cross-reacted with the positive-control. i.e.
human angiosarcoma tissue, suggesting that IBI305 is highly specific to cancer tissues
rather than normal human tissues and has very low on-target toxicity.
2)
Linearity: With single dose or repeated doses of IBI305 (2-50 mg/kg) vis intravenous
injection in cynomolgus monkeys, the test showed significant PK, thus reducing the
suddenly rising toxicity risks with increased clinical doses.
3)
Immunogenicity: With single dose or repeated doses of IBI305 or bevacizumab via
intravenous injection in cynomolgus monkeys, the test showed abnormal changes of
drug concentration-time curves in several animals. The anti-drug antibody (ADA) test
results showed that IBI305 has a medium immunogenicity.
4)
Accumulation: With repeated doses of IBI305 or bevacizumab via intravenous
injection in cynomolgus monkeys, the test showed that drug exposure of the last
dose was significantly higher than that of the first dose, and the steady-state drug
concentration after repeated doses was higher than that after a single dose, suggesting
that the drug may be accumulated in body.
The results of tissue cross-reactivity and PK/toxicokinetic studies in cynomolgus monkeys
indicated that IBI305 and bevacizumab have similar characteristics in tissue cross-reactivity and
PK/toxicokinetics13.
Toxicological studies
Toxicological studies of IBI305 showed the following findings:
1)
Single dose: With single dose of IBI305 (up to 300 mg/kg) via intravenous injection in
cynomolgus monkeys, the test showed good tolerability without any abnormal clinical
symptoms and toxicity. The dose was about 48 times the proposed clinical dose for
human based on body surface area. In the safety pharmacology test, with single dose of
IBI305 (50 mg/kg) via intravenous injection in cynomolgus monkeys, the test showed
no significant effects on the central nervous system, respiratory system, and
cardiovascular system, suggesting that the single dose of IBI305 via intravenous
injection has a high safety.

2)
Repeated doses: With repeated doses of IBI305 (up to 50 mg/kg) via intravenous
injection twice weekly for 9 consecutive doses in cynomolgus monkeys, equivalent to
20 times the proposed clinical dose for humans (based on the weight), the test showed
extremely mild to mild linear growth arrest of metaphyseal lines at knee joint and
disordered chondrocyte proliferation, extremely mild increases in macrophage count
in white pulp of spleen, pulmonary (including bronchial) hemorrhage, and deposits of
hemosiderin in lymphoid tissue of bronchial mucosa, indicating that the target organ
toxicities are mainly in the bone, spleen, and lungs.
3)
Immunotoxicity and immunogenicity: With repeated doses of IBI305 via intravenous
injection twice weekly for 9 consecutive doses in cynomolgus monkeys, the test
showed medium immunotoxicity to the spleen. Different doses of IBI305 may result in
the production of ADAs, a portion of which are neutralizing antibodies (NAbs),
indicating that IBI305 has medium immunotoxicity and immunogenicity.
4)
Local irritation test: With repeated dose of IBI305 via intravenous injection in
cynomolgus monkeys, the test showed no irritation at the injection site, suggesting that
administration of IBI305 via intravenous injection is safe and feasible.
5)
In vitro hemolysis assay: With maximum proposed clinical concentration of IBI305
(9 mg/mL), the assay showed no hemolysis, suggesting that IBI305 is suitable for
intravenous injection.
IBI305 has high similarity with bevacizumab in safety pharmacology, long-term toxicity,
immunotoxicity, immunogenicity, local irritation, and hemolysis13.
1.2 Study Principles and Risk/Benefit Assessment
1.2.1 Study principles and dose selection
A biosimilar drug refers to a therapeutic biological product that is similar in quality, safety and
efficacy with an approved reference drug14. IBI305, developed and sold in the market by the
sponsor, is a bevacizumab biosimilar, and has the same administration method and indications
as bevacizumab.

Confidential
This study is conducted in accordance with the "Guidelines on Development and Evaluation of
Bosimilars (for Trial Version)" issued by the NMPA (formerly CFDA)14. The doses of IBI305
selected in this study are based on the preclinical studies that showed highly similarity between
IBI305 and bevacizumab in pharmacology, PD, PK and toxicology (refer to the Investigator's
Brochure for details). Besides, the efficacy and safety of bevacizumab for treatment of advanced,
metastatic or relapsed non-squamous NSCLC have been verified, and the indications have also
been approved in China. Therefore, the dose and administration of IBI305 is similar to
bevacizumab in this study, that is, 15 mg/kg intravenously on D1 of every 3-week cycle
when used in combination with chemotherapy (paclitaxel and carboplatin). In the subsequent
maintenance monotherapy therapy, IBI305 will be given intravenously at a dose of 7.5 mg/kg on
the first day of every 3-week cycle. This design of this study is to further demonstrate that
IBI305 is similar to bevacizumab in clinical efficacy, safety, and immunogenicity in subjects
with advanced, metastatic or relapsed non-squamous NSCLC.
1.2.2 Risk/benefit assessment
IBI305 is a bevacizumab biosimilar developed by the sponsor. Based on the clinical pharmacology
and toxicology characteristics of IBI305, the risks and benefits of IBI305 are expected to be similar
to bevacizumab.
The treatment-related risks of bevacizumab are detailed in its prescribing information. This study
is the first human study of IBI305 so that unexpected adverse reactions will be possible. The
design of this study ensures the minimized subject risks by close monitoring of the adverse
events (AEs) before, during, and after the infusion of the investigational drugs. Once an adverse
reaction occurs, the investigator will immediately take appropriate action for the subject safety.
The platinum-based therapy is the standard first-line regimen of advanced NSCLC4. This study
uses the combination of paclitaxel/carboplatin, ensuring the basic anti-tumor therapy for subjects.

3 STUDY PLAN
3.1 Overview of Study Design
This is a randomized, double-blind, active-controlled, and multi-center phase III study. A total of
436 subjects across 35 study sites with non-squamous NSCLC will be planned, randomized in a
1:1 ratio into the IBI305 plus paclitaxel/carboplatin group or bevacizumab plus paclitaxel/carboplatin
group, and stratified according to age (< 60 vs. ≥60 years old) and epidermal growth factor
receptor (EGFR) status (wild type vs. unknown type). Each treatment cycle is 3 weeks for both
groups. 15 mg/kg IBI305 or bevacizumab is administered on D1 of each cycle along with
paclitaxel/carboplatin. Subjects will receive up to 6 treatment cycles of combination therapy until
PD, unacceptable toxicity, withdrawal of informed consent, loss of follow-up, or death
(whichever comes first). Then subjects received maintenance monotherapy, that is, discontinuing
paclitaxel/carboplatin while continuing maintenance therapy with IBI305 or bevacizumab. The
maintenance monotherapy continues every 3 weeks. On D1 of each treatment cycle, subjects will
be administered 7.5 mg/kg of either IBI305 or bevacizumab until PD, unacceptable toxicity,
withdrawal of informed consent, lost to follow-up, death, or end of study (whichever comes first).
After discontinuing the study drug, subjects will return to the study site 28 days (± 7 days) after
the last dose for an end-of-treatment visit. If the subjects discontinue the study treatment for
reasons other than PD, subsequent follow-up will be continued until PD, withdrawal of informed
consent, start of other anti-tumor therapies, loss of follow-up, death, or end of study. If the
subjects discontinue the study treatment for PD, the investigator will make telephone follow-up
every 12 weeks (± 7 days) to collect information of subsequent anti-tumor therapies and survival.
A CT or an MRI will be performed every 6 weeks (± 7 days) until PD, withdrawal of informed
consent, start of other anti-tumor therapies, loss of follow-up, death, or end of study. The method
for subsequent imaging examination should be consistent with that at baseline, and the chest,
abdomen and pelvis of the subject must be scanned. Each assessment must be completed within
7 days from the most recent visit. The investigators then perform the evaluation based on the
RECIST v1.1 criteria to determine whether the subject can continue receiving the next cycle of
treatment. Furthermore, the independent tumor evaluation committee (Section 11.1.1) will also
evaluate tumor response according to the RECIST v1.1. If the subjects discontinue the study
treatment for reasons other than PD, subsequent tumor evaluation should be continued according
to the study procedures until PD, withdrawal of informed consent, start of other anti-tumor
therapies, loss of follow-up, death or, end of study.
The study design is shown in Figure 1.

5 STUDY TREATMENT
5.1 Therapies by Study Drugs
The study drugs of this study are IBI305 and bevacizumab.
In this study, the dose of IBI305 or bevacizumab during combination therapy with chemotherapy
is 15 mg/kg, while the dose during maintenance monotherapy is 7.5 mg/kg. The study drugs are
administered intravenously on D1 of each 3-week cycle until PD, unacceptable toxicity,
withdrawal of informed consent, loss to follow-up, death, or end of study (whichever comes first).
The duration of the first dose of IBI305 or bevacizumab should be 90 min (± 15 min). If the
first infusion is well-tolerated by the subject, then the duration of the second infusion can be
shortened to 60 min (± 15 min). If the 60 min infusion is also well-tolerated by the subject, then
the subsequent infusions can be completed within 30 min (± 15 min).
5.2 Chemotherapy
Paclitaxel will be administered after the IBI305 or bevacizumab infusion is completed, then
followed by carboplatin:
Paclitaxel: 175 mg/m² administered via intravenous infusion for 3 h (may be adjusted according
to clinical practice of each study site) on D1 of every 3-week cycle for up to 6 cycles until PD,
unacceptable toxicity, withdrawal of informed consent, loss of follow-up, or death.
Carboplatin: AUC 6.0, the infusion time is based on the standard practice of each study site,
administered on D1 of every 3-week cycle for up to 6 cycles until PD, unacceptable toxicity,
withdrawal of informed consent, loss of follow-up, or death.
The chemotherapeutic agents are supplied by the sponsor.
Formulas for calculating surface area, creatinine clearance and carboplatin dose are shown in
Section 13.2.
5.3 Dose Adjustment of Each Study Drug
5.3.1 General principles
The reasons for dose adjustments or delayed administration, measures taken, and
results should be documented in the medical records and eCRFs

Confidential
If the concomitant symptoms exist at baseline, the investigator will determine whether
the dose should be adjusted according to the change in severity of toxicity. For example,
if the subject has Grade 1 "weakness" at baseline and Grade 2 "weakness" during the
study treatment, the dose should be adjusted based on Grade 1 toxicity since the
severity has increased by one grade
If several toxic reactions of different grades or severity occur simultaneously, the dose
will be adjusted according to the highest observed grade/severity
If a dose adjustment is required solely due to abnormal lab test results, then the dose
should be adjusted based on the measured values obtained prior to the start of the
treatment cycle
If the investigator determines that the toxicity is unlikely to further develop into a
serious or life-threatening event, the current dose will be continued without any
adjustments or treatment interruptions. In addition, dose adjustments or treatment
interruptions will not be performed for non-hemolytic anemia as the symptoms can be
alleviated through blood transfusions.
If the investigator determines that a toxicity is caused by a specific therapeutic drug,
then the dose adjustments of other drugs are not required
Discontinuation of one or two therapeutic drugs before PD will not affect the continued
treatment with other drugs
Dose reductions or adjustments of IBI305 or bevacizumab are not permitted.
Subsequent therapeutic dose will not be adjusted according to weight change, unless
the subject weight has changed by ≥10% from baseline
Once the dose of any chemotherapeutic agents is reduced, the original dose should no
longer be adopted
If any but not all of the therapeutic drug (IBI305, bevacizumab or chemotherapeutic
agents) treatments is interrupted due to toxicity, then this treatment will be considered
as a treatment cycle
If the administration of any one of the chemotherapeutic agents is delayed for more
than 3 weeks, the subject should permanently discontinue that chemotherapeutic agent

5.3.2 Dose adjustments of study drugs
Dose adjustments of IBI305 or bevacizumab are not permitted except for the adjustments
(adjusted to 7.5 mg/kg for maintenance monotherapy) specified in the study protocol. The dose
of IBI305 or bevacizumab is calculated according to the subject weight at baseline (prior to the
first dose), and remains unchanged throughout the study, unless the subject weight has changed
by ≥10% from baseline.
If an infusion reaction occurs during a 60-minute infusion, the infusion time should be extended
to 90 minutes for all subsequent infusions. Likewise, if an infusion reaction occurs during a 30-
minute infusion, the infusion time should be extended to 60 minutes for all subsequent infusions.
IBI305 or bevacizumab in combination with paclitaxel/carboplatin will be administered every
3-week treatment cycle for 6 cycles. If PD is not observed in subject during treatment, then the
subject will continue to receive IBI305 or bevacizumab as maintenance monotherapy every 3-
week treatment cycle until PD, unacceptable toxicity, withdrawal of informed consent, loss of
follow-up, death, or end of study (whichever comes first).
If IBI305 or bevacizumab is permanently discontinued due to unacceptable toxicity or subject
refusal to continue the study drugs during the combination therapy, then the subject will continue
to receive the chemotherapy (paclitaxel/carboplatin) until 6 treatment cycles are completed as
determined by the investigator. If any one of the chemotherapeutic agents (paclitaxel or carboplatin)
is prematurely discontinued due to unacceptable toxicity, the subject can continue to receive
IBI305 or bevacizumab treatment until PD, unacceptable toxicity, withdrawal of informed
consent, loss of follow-up, or death (whichever comes first).
When a Grade 3 or 4 IBI305- or bevacizumab-related toxicity is observed, the investigators
should determine whether to continue or terminate IBI305 or bevacizumab treatment according
to the followings:
First occurrence:
IBI305 or bevacizumab administration should be interrupted until toxicity symptoms return to
baseline level or are at least reduced to the Common Terminology Criteria for Adverse Events
(CTCAE) Grade 1 or lower (except for the special circumstances listed below)
Note that when Grade 4 febrile neutropenia and/or thrombocytopenia occur(s), IBI305
or bevacizumab administration should be interrupted until the symptoms return to
baseline levels or at least reduced to CTCAE Grade 1 or lower, since these events
increase the risk of hemorrhage.

Re-occurrence in re-administration:
If Grade 3 IBI305- or bevacizumab-related toxicity occurs again, the investigator
should assess the risk/benefit of study drug continuation for the subject. If such toxicity
re-occurs again after re-administration, IBI305 or bevacizumab should be permanently
discontinued
If Grade 4 IBI305- or bevacizumab-related toxicity occurs again, IBI305 or
bevacizumab should be permanently discontinued
Measures should be taken in the following special circumstances (classified based on CTCAE
version 4.03):
Hemorrhage
Subjects with Grade 3 or 4 hemorrhages should be treated accordingly and permanently
discontinue the study treatment
Thrombosis/embolism

Subjects with arterial thrombosis of any severity grades should permanently
discontinue the study treatment

Subjects with Grade 4 venous thrombosis should permanently discontinue the
study treatment

Subjects with Grade 3 venous thrombosis should interrupt the study treatment. If
the anticoagulant therapy at the planned therapeutic dose is < 2 weeks, the study
treatment should be interrupted until the anticoagulant therapy is completed. If
the anticoagulant therapy at the planned therapeutic dose is > 2 weeks, IBI305
or bevacizumab administration should be interrupted for 2 weeks, and the study
treatment can be restarted during the anticoagulant therapy if the following criteria
are met:
- INR is within the target range (usually 2-3) prior to restarting of study treatment
- Subjects must not have experienced Grade 3 or 4 hemorrhage since enrollment
- No signs of great vessel invasion or adjacency to great vessels from previous
tumor assessments
Note: Therapeutic dose of anticoagulant therapy is defined as the escalating dose of
warfarin or other anticogulants until INR is maintained at no less than 1.5 (usually

2-3). The warfarin dose should be documented in the eCRFs, and the INR of
subjects receiving anticoagulant therapy should be monitored during the treatment.
Hypertension
BP should be measured frequently to monitor the occurrence and exacerbation of hypertension.
Subjects should remain at resting position for at least 5 min before BP measurement.
Grade 1 hypertension: Asymptomatic transient (< 24 h) increase in BP (> 20 mmHg
diastolic blood pressure), or > 150/100 mmHg in this measurement, but previous BP
was within normal range. No interventions are required.
Grade 2 hypertension: Repeated or sustained (> 24 h) or symptomatic BP increase (>
20 mmHg diastolic blood pressure), or > 150/100 mmHg in this measurement, but
previous BP was within normal range. One antihypertensive drug can be used. Once
BP is lowered to < 150/100 mmHg, the subject may continue the study treatment.
Grade 3 hypertension: Requires more than one antihypertensive drugs or more potent
treatment. Study treatment should be interrupted in case of persistent or symptomatic
hypertension; study treatment should be permanently discontinued for uncontrollable
hypertension.
Grade 4 hypertension: Life-threatening (i.e. hypertensive crisis). The study treatment
should be permanently discontinued in case of Grade 4 hypertension. The dose of all
antihypertensive agents used should be documented during each visit.
The dose of antihypertensive agents used should be documented during each visit. If the subject
remains hypertensive despite treatment discontinuation, BP and antihypertensive agents used
should be monitored every 3 months until BP returns to normal or end of study.
Posterior reversible encephalopathy syndrome (PRES)
There have been a few reports of subjects with signs and symptoms consistent with PRES after
study treatment. This is a rare neurological disease and its signs and symptoms include epilepsy,
headache, altered mental status, visual impairment, or cortical blindness, with or without
hypertension. Subjects with PRES should permanently discontinue the study treatment.
Proteinuria
Urinalysis dipstick test should be performed prior to each IBI305 or bevacizumab infusion unless
24-h proteinuria test has already been performed.

First occurrence of proteinuria:
The urinalysis dipstick test should be performed if:
Urine protein is < 2+, continue study treatment as scheduled, no additional tests are
required.
Urine protein is ≥2+ (strip test), continue study treatment as scheduled, and a 24-h
urine protein test should be performed within 3 days prior to the next treatment cycle:

If 24-h urine protein is < 2 g, continue study treatment as scheduled, and perform
urinalysis dipstick test before each scheduled dose.

If 24-h urine protein is > 2 g, the current study treatment is interrupted, and a 24-h
urine protein test should be performed within 3 days prior to the next planned dose.
Study treatment is delayed until 24-h urine protein is ≤2 g, and a 24-h urine protein
test prior to each subsequent dose is performed until urine protein is reduced to ≤
1 g/24 h. Interrupt study treatment only when 24-h urine protein is > 2 g.
Second and subsequent occurrence of proteinuria:
< 3+ (strip test): continue study treatment as scheduled, no additional tests are required.
Urine protein is ≥3+ (strip test), continue study treatment as scheduled, and a 24-h
urine protein test should be performed within 3 days prior to the next treatment cycle:

If 24-h urine protein ≤2 g, continue study treatment as scheduled.

If 24-h urine protein is > 2 g, the current study treatment is interrupted, and a 24-h urine
protein test should be performed within 3 days prior to the next planned dose. Study
treatment is delayed until 24-h urine protein is ≤2 g, and a 24-h urine protein test
prior to each subsequent dose is performed until urine protein is reduced to ≤
1 g/24 h. Interrupt study treatment only when 24-h urine protein is > 2 g.
Nephrotic syndrome (Grade 4): Study treatment is permanently discontinued
Gastrointestinal perforation
If gastrointestinal perforation occurs, appropriate measures should be taken and the study
treatment should be permanently discontinued.
Wound healing complications
The study treatment should not begin within 28 d after a major surgery, or before the surgical

wound is fully healed. If a complication of wound healing occurs during study treatment, the
study treatment should be interrupted until the wound is fully healed. If an elective surgery is
required, the study treatment should be interrupted.
Abdominal abscess or fistula
If abdominal abscess or fistula occurs, the study treatment should be discontinued. However, the
investigator will determine whether study treatment will be continued if the above AE is resolved.

Infusion-related and allergic reactions:
Infusion-related reactions after first dose of the study drug is uncommon (< 3%), and the incidence
of a severe reaction is only 0.2%.
If a mild (grade 1 or 2) reaction (such as fever, chills, headache, and nausea) occurs, pretreatment
prior to subsequent administration should be performed and infusion time should not be reduced.
If the subject is well-tolerated during infusion after pretreatment, the infusion time can be
reduced by 30 minutes (+10 minutes) for subsequent administration with pretreatment. If an
infusion-related AE occurs during a 60-minute infusion, the subsequent infusion should be
completed within 90 minutes (+15 minutes) with pretreatment. Likewise, if an infusion-related
AE occurs during a 30-minute infusion, the subsequent infusion should be completed in 60 minutes
(+10 minutes) with pretreatment. If a subject has a grade 3 infusion-related reaction, the study
treatment should be interrupted and not be restarted on the same day. However, since there lacks
the dose adjustment method for grade 3 infusion-related reactions, the investigators may decide
to either discontinue the study drug or perform pretreatment, and complete the infusion within
90 minutes (+15 minutes). If an adverse reaction still occurs during a 90-minute infusion, the
infusion should be continued at a slower rate and then gradually returned to a 90-minute infusion.
If the investigator is uncertain about the handling, the study treatment should be discontinued.
When the study treatment is restarted, the subject should be closely monitored based on routine
clinical practice until the possible time of adverse reaction has passed. If a subject has a grade 4
infusion-related reaction, the study treatment should be discontinued.
An allergic reaction is defined as the vascular collapse or shock (systolic BP < 90 mmHg,
unresponsive to rehydration) that occurs within 30 minutes of a study drug infusion caused by
an allergy, with or without respiratory distress. Skin reactions include pruritus, urticaria, and
angioedema. Subjects with allergic reactions should discontinue the study treatment.
5.3.3 Dose adjustments of chemotherapy
Paclitaxel and carboplatin should be administered according to the study site guidelines and local
prescribing information. For the specific information for use, preparation, and storage of
paclitaxel and carboplatin, refer to the prescribing information and local dosing information.
Carboplatin-based chemotherapies have a relatively high incidence of emesis. Therefore,
antiemetics for prophylaxis can be used.
Hematological toxicity:
Absolute neutrophil count (ANC; dose can only be reduced when febrile neutropenia occurs.
ANC must be ≥1.5 × 109/L and platelet count ≥100 × 109/L on D1 of each treatment cycle)

Once the chemotherapeutic dose is reduced due to febrile neutropenia or thrombocytopenia
(platelet count < 25 × 109/L or < 50 × 109/L with hemorrhage or blood transfusion required), the
original dose should no longer be adopted. If dose reduction is required due to another incident
of febrile neutropenia or thrombocytopenia, the dose of paclitaxel and carboplatin will be
reduced to 100 mg/m2 and AUC 3.0, respectively. If the dose reduction is required for the third
time, the chemotherapy should be immediately discontinued.
If the dose adjustment is required when ANC and thrombocytopenia occur concurrently, the low-
dose chemotherapy should be adopted.
Chemotherapy may be delayed for up to 3 weeks. If after the chemotherapy has been delayed for
3 weeks, ANC does not reach ≥1.5 × 109/L and platelet count does not reach ≥100 × 109/L on
D1 of the scheduled chemotherapy, the chemotherapy should be permanently discontinued. If the
above values have been reached, the next course of chemotherapy should be continued.
The investigator should monitor the subject closely for toxicity with particular attention to early
and evident signs of myelosuppression, infection, or febrile neutropenia to timely and
appropriately treat the complications.
Subjects should be informed to pay attention to these signs and receive treatment as soon as possible.

If the chemotherapy must be interrupted due to hematological toxicity, the complete blood count
should be performed regularly (including WBC differentials) until all the counts reach the
minimum requirements for treatment continuation. Thereafter the scheduled treatment plan will
be performed.
Dose adjustments are not required for anemia. However, treatment based on guidelines of each
clinic should be performed.
Gastrointestinal toxicity
Antiemetics will be used to control nausea and/or emesis. If grade 3 or 4 nausea and/or emesis
occur(s) despite of antiemetics, the chemotherapeutic dose should be reduced by 20% for the
next treatment cycle. The dose should be returned to the initial level as possible if the subject is
tolerated.
If the subject experiences stomatitis on D1 of any treatment cycle, the chemotherapy should be
interrupted until the symptoms resolve. If the stomatitis has not resolved after 3 weeks, the
chemotherapy should be permanently discontinued (refer to CTCAE version 4.03). If an acute
Grade 3 stomatitis occurs, the chemotherapeutic dose should be reduced to 75% of the proposed
dose when symptoms resolve.
Hepatotoxicity (Paclitaxel)
The paclitaxel dose should be determined based on the lab values measured on D1 of each
treatment cycle.

If paclitaxel is interrupted due to hepatotoxicity, carboplatin should also be interrupted until
paclitaxel is restarted. Paclitaxel will be interrupted for up to 3 weeks. If the subject's hepatic
function does not return to the acceptable ranges in 3 weeks, paclitaxel should be permanently
discontinued. The carboplatin dose will not be adjusted when hepatotoxicity occurs.

The investigators should avoid PD due to abnormal hepatic enzyme levels as possible. If PD
occurs, all the study drugs should be permanently discontinued, including chemotherapy.
Cardiovascular toxicity (paclitaxel)
The arrhythmia in subjects was infrequent in previous clinical studies. However, most subjects
were asymptomatic and electrocardiographic monitoring was not required. Asymptomatic
transient bradycardia was observed in 29% of subjects, but significant atrioventricular block was
rare. Cardiac events should be treated as follows:
Asymptomatic bradycardia: no intervention indicated
Symptomatic arrhythmia during infusion: Discontinue paclitaxel infusion and perform
routine treatment of arrhythmia. Discontinue subsequent paclitaxel treatment.
Document this AE in the AE Report Form of eCRF.
Chest pain and/or symptomatic hypotension (< 90/60 mmHg or rehydration therapy
required): discontinue the paclitaxel infusion. Perform electrocardiography (ECG). If
hypersensitivity reaction is suspected, administer diphenhydramine and dexamethasone
via intravenous infusion. If the chest pain is not considered as cardiogenic, epinephrine
or bronchodilators will be administered. Document this AE in the AE Report Form of
eCRF. Discontinue subsequent paclitaxel treatment and provide symptomatic treatment.
Consult a cardiologist if needed.
Neurotoxicity (paclitaxel)
The dose of paclitaxel should be adjusted according to Table when neuropathy occurs. The dose
adjustment of carboplatin is not needed when neurotoxicity occurs.

If the neurotoxicity does not return to grade 1 after paclitaxel interruption for 3 weeks, paclitaxel
should be permanently discontinued.
Allergic reactions/hypersensitivity reactions (paclitaxel)
Note: Prophylaxis for hypersensitivity reactions (see below) and close monitoring of vital signs
are recommended for subjects with history of mild to moderate hypersensitivity reactions when
hypersensitivity reactions reoccur.
Mild symptoms: complete paclitaxel infusion. Close monitoring; no treatment indicated.
Moderate symptoms: Interrupt paclitaxel infusion, administer diphenhydramine 25–
50 mg and dexamethasone 10 mg via intravenous infusion. Once symptoms have
resolved, resume paclitaxel infusion at a slower rate (20 mL/hour for 15 minutes, then
at 40 mL/hour for 15 minutes, and if no further symptoms develop, continue at original
rate until infusion is complete). Document this AE in the AE Report Form of eCRF. If
symptoms reoccur, interrupt the paclitaxel infusion and permanently discontinue
subsequent paclitaxel infusion.
Severe and life-threatening symptoms: Interrupt paclitaxel infusion, administer
diphenhydramine and dexamethasone via intravenous infusion (as above). Use
epinephrine or bronchodilators if indicated. Document this AE in the AE Report Form
of eCRF. Subsequent courses of paclitaxel infusion should be permanently
discontinued.
Moderate or severe hypersensitivity reactions should be documented as AEs.
Other toxicities
If other unmentioned grade 3–4 toxicities occur, the chemotherapy should be interrupted until
symptoms resolve or return to grade 1. Thereafter restart the infusion at 50% of the original dose
(which should no longer be adopted). If the toxicity does not return to grade 1 after an
interruption for 3 weeks, the chemotherapy should be permanently discontinued. Dose
adjustments are not recommended for grade 1 and 2 toxicities.
5.4 Study Drug Properties
IBI305 is a bevacizumab biosimilar. The active ingredient of both drugs is recombinant humanized
anti-VEGF monoclonal antibody; Bevacizumab is the standard commercially available drug, provided

5.5 Preparation and Distribution
IBI305 or bevacizumab is diluted in 0.9% sodium chloride solution by the pharmacist or research
nurse before infusion. Check the particles and discoloration prior to administration.
The investigator should ensure that the pharmacist or research nurse administers the study drugs
according to study protocol.
5.6 Packaging, Labeling, and Storage
The sponsor should package and label the study drugs according to appropriate local regulations.
All study drugs (IBI305 and bevacizumab) must be stored at 2–8 °C away from light. The study
drugs should be stored in a safe zone only accessible by authorized staff prior to dispensation to
the subjects.
5.7 Subjects Allocation
After confirming that the subject meets all of the inclusion and exclusion criteria, the study site
will log in the Interactive Web Response System (IWRS) and enter the subject information into
the IWRS. The IWRS will allocate a random number to the subject and provide a medication
number. Stratified randomization is used in this study. Stratifying factors include age (< 60 vs.
≥60 years old) and EGFR status (wild vs. unknown type).

5.8 Blinding
This is a randomized, double-blind, and active-controlled study, and only relevant study
personnel had access to the randomization numbers. A non-blinded pharmacist or research nurse
will prepare the medications since IBI305 and bevacizumab do not have an identical appearance.
The pharmacist or research nurse who is responsible for preparing the study drugs is not allowed
to disclose any information regarding treatment allocation to the subject, the subject's family
members, or other personnel including the physician and the relevant study staff.
Unblinding: Subject unblinding should only be performed after database locking.
Emergency unblinding: In case of an emergency where the investigator must know the
medication given to a particular subject, the investigator will unblind the subject via the IWRS
and immediately inform the sponsor and CRO. The reasons for unblinding, date, and outcomes
should be documented in the source document and eCRF of the subject.
5.9 Concomitant Medications and Treatments
All medications except for the study drugs, including other chemotherapies not specified in the
study, Chinese herbal medicines, and other non-traditional therapies, are considered concomitant
medications. All concomitant medications used within 30 days prior to screening should be
documented in the eCRFs, including the information of generic name, route of administration,
start date, end date, and indication.
5.9.1 Prohibited medications
No other anti-tumor therapies or medications with anti-tumor indications, including Chinese
herbal medicine, radiotherapy, or other investigational drugs, are allowed during this study other
than IBI305, bevacizumab, paclitaxel, and carboplatin.
Severe myelosuppression is possible after chemotherapy. Granulocyte colony-stimulating factor
or granulocyte-macrophage colony-stimulating factor are not allowed to be used prophylactically
in the first treatment cycle.
5.9.2 Medications allowed
Prophylactic use of anti-emetics, glucocorticoids, or other treatments targeting toxicities is permitted
during the study. Unconventional treatments (such as acupuncture) and vitamins/microelements are
permitted if their use does not affect the study endpoints as determined by the investigators.

myelosuppression.
5.9.3 Treatment after study treatment
Subsequent therapy after the end of study treatment should be determined by the subject's
attending doctor.
5.10 Treatment Compliance
Subjects should receive treatment at the study site. The dose and time of administration of
IBI305 or bevacizumab and paclitaxel/carboplatin should be documented in the source records
and eCRFs during each treatment cycle. Reasons for dose adjustments, therapy delay, and
therapy discontinuation should be documented. Treatment compliance is monitored by
medication dispensing and return records, medical records, and eCRFs.
5.11 Drug Return and Destruction
The containers, vials, infusion bags, and syringes of used and partially used drugs can be
destroyed on-site according to the appropriate guidelines and operating procedures established
by study sites and local agencies.
Unless the contents have significant safety issues requiring immediate destruction in accordance
with local regulations, all the unused drugs should be returned and destroyed based on the
requirements of sponsor.

6.13 Tumor Assessment
Imaging tests (CT or MRI) of the brain, chest, abdomen, and pelvis are required at baseline. If
these tests are performed within 28 days prior to the first dose of the study drug, they do not need
to be repeated unless the investigator believes that there have been changes in the subject's tumor
burden. After the start of treatment, imaging tests are performed once every 6 weeks (±7 days)
and have to be completed within 7 days prior to the scheduled visits, until progressive disease,
start of other treatment, withdrawal of informed consent, loss to follow-up, death, or study
completion. The same method of imaging test was used at baseline and during follow-up.
Imaging evaluations of the chest, abdomen, and pelvis are required.
The investigator should perform a tumor assessment based on RECIST v1.1 (Section 13.3) prior
to each dose to determine whether the subject should continue with the next round of treatment.
An independent review committee will also assess the tumor response (Section 11.1.1). Imaging
tests will not be rescheduled if the study drugs or chemotherapeutic agents are interrupted due to
toxicities. Every effort should be made to continue the schedule for imaging tests even for
subjects who discontinue one or two study treatment(s) due to drug-related toxicities.
If subject experience PD according to the RECIST v1.1 criteria, the attending doctor should
discuss with the subject regarding subsequent routine cancer therapies.
6.14 Clinical Laboratory Evaluations
Clinical laboratory tests will be conducted at the laboratories of each study site. Sample collection
and analysis should be performed according to the requirements of each laboratory.
The following laboratory tests should be conducted according to the study procedures (Table 1.

documentation, the subject will not be required to be retested). The testing will be conducted at
the laboratory of each study site or a qualified third-party laboratory.

7 STUDY ASSESSMENTS
7.1 Efficacy Assessment
7.1.1 Primary efficacy endpoint

Objective response rate (ORR)
ORR will be assessed using RECIST v1.1. ORR is defined as the proportion of subjects whose
tumor volume has reduced to a predetermined value for a minimum time limit, including patients
who achieved complete response (CR) and partial response (PR). The cutoff date for the primary
efficacy endpoint analysis of this study is 6 months after subject randomization.
7.1.2 Secondary efficacy endpoints

Duration of response (DOR)

Progression-free survival (PFS)

Disease control rate (DCR)

Overall survival (OS)
Each endpoint will be assessed using RECIST v1.1.
DOR is defined as the time from initial tumor response (CR or PR) to PD or death before PD;
Subjects with CR or PR who do not progress or die will be censored on the date of the last tumor
assessment.
PFS is defined as the time from the date of randomization to the date of PD or death; Subjects
who do not progress or die will be censored on the date of the last tumor assessment.
DCR is defined as the proportion of patients whose tumor volume has reduced to a
predetermined value for a minimum time limit, including patients who achieved CR, PR, and SD.
OS is defined as the time from the date of randomization to the date of death of any cause. For
subjects that are alive on the date of study completion or are lost to follow-up, their survival time
will be censored at the date of last contact.

7.2 Safety Assessments
7.2.1 Adverse events
7.2.1.1 Definition
Adverse event
An AE refers to any untoward medical occurrence in a subject after signing the informed consent
form, and does not necessarily have a causal relationship with the treatment. Thus, an AE can be
any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or
disease, whether considered drug related.
Abnormalities resulting from PD are not considered as AEs.
Serious adverse event
A SAE refers to an AE meeting at least one of the followings:
(1) Lead to death, except for deaths caused by PD.
(2) Life-threatening (a "life-threatening event" is defined as an AE when the subject is at
immediate risk of death at the time, but does not include the case that may lead to death
only when the event worsens).
(3) Requires hospitalization or prolonged hospitalization, excluding an emergency or
outpatient visit. Subjects with existing diseases or conditions prior to the enrollment
that do not worsen during the study, and having hospitalization and/or surgery that was
scheduled before the study or during the study do not meet the SAE criterion.
Hospitalizations resulting from PD are not considered as SAEs.
(4) Results in permanent or severe disability/incapacity.
(5) Results in congenital anomalies/birth defects.
(6) Other important medical events: The event that does not result in death, is not life-
threatening or does not require hospitalization, but may jeopardize the health of
subjects and require medical intervention to prevent the SAEs above, is considered as
an SAE
7.2.1.2 Severity of adverse events
The severity of AEs is evaluated using the 5-level criteria of NCI CTCAE v4.03.
For AEs not included in CTCAE v4.03, use the following CTCAE general guidelines:

Cannot be determined

The above information is unclear and cannot be determined based on the
available information. Further follow-up information is not accessible to
the investigator.
7.2.1.4 Serious adverse event reporting
The investigator should immediately take appropriate medical measures to treat any SAE that
occurs during the trial. And the SAE should be recorded in the tables of adverse events and
serious adverse events in the eCRF and source documents; regardless of whether the SAE is
related to the treatment, the investigator must submit the completed SAE report form to the
sponsor within 24 hours of noticing the event. The investigator shall urgently perform visit on
missing information and provide a complete SAE report for events that result in death or are life-
threatening.
Contact information for the reporting of SAE/pregnancy to the sponsor:
Fax: 021-31652800
SAE reporting email: drugsafety@innoventbio.com
When submitting the SAE report by email, it is recommended for the investigator to encrypt the
report file and send the report file and password in separate emails.
At the same time, the investigator should follow the SAE reporting procedures issued by relevant
regulatory authorities or the independent ethics committee.
The investigator should follow up the SAE until it disappears or recovers to a result that the
investigator believes it can be explained without further follow-ups, such as clinical stability or
improvement. The time limit for the follow-up report and the report of answered queries is the
same as that for the initial report.
7.2.1.5 Management and follow-up of adverse events
The investigator is responsible for providing appropriate medical treatment for all AEs (Indicate
the actions taken, such as suspension/termination of the investigational drug, dose modification,
drug therapy, etc.). When an AE occurs, the investigator should actively take appropriate
measures to ensure the safety of the subject. All AEs observed from the signing of the ICF
to the time specified in the protocol (Table 2) must be followed.

The investigator should report any SAE that occurs after the time specified in the protocol (Table 2)
and is suspected of being related to the investigational drug to the sponsor.
7.2.1.6 Adverse event of special interest and expedited reporting
The AESI for this study include:

Gastrointestinal perforation

Procedural and wound healing complications

Hemorrhage

Fistula

Hypertension

Thrombotic event

Posterior reversible encephalopathy syndrome (PRES)


Cardiac failure congestive
Among them, Grade 2 gastrointestinal perforation, procedural and wound healing complications,
hemorrhage, fistula, arterial thrombotic events and proteinuria, and all above adverse events of
special interest (AESIs) of Grade 3 and above should be reported as AESIs to the sponsor in
accordance with the SAE reporting time limit and procedures (see 7.2.1.4 for details) even if they
do not meet the SAE definition.
7.2.1.7 Pregnancy
Bevacizumab may be harmful to the fetus. Subjects or female partners of male subjects must use
an effective form of contraception during the 6 months after the last dose. If any female subject or
the female partner of any male subject becomes pregnant during the study, the drug should be
discontinued immediately and the investigator should be notified. The investigator should report
the pregnancy to the sponsor within 24 h of knowing the event by filling out the pregnancy form.
The Investigator should also discuss with the subject (and the female partner of the male subject)
regarding the risk of continuing pregnancy and its possible impact on the fetus. The investigator
should follow up the pregnancy to determine its outcome (including abortion) and the status of the
mother and the baby for not less than 8 weeks after delivery, and report the follow-up results as the

pregnancy follow-up report to the sponsor according to the procedure and time limit the same as
those for the first report. Complications and termination of pregnancy due to medical reasons
should be reported as AE or SAE. A spontaneous abortion should be reported as an SAE. For any
congenital abnormalities/birth defects or SAEs of the mother and child during the perinatal period,
they should be recorded and reported in accordance with the procedure and time limit for reporting
SAEs.
The investigator should pay attention to any pregnancy-related SAE that occurs after study
completion. Any SAE that the investigator believes may be related to the study treatment should
be reported immediately to the sponsor.
7.2.1.8 Time limits of documenting and reporting AEs
All AEs occurring from the time the subject signs the informed consent form to the time
specified in the protocol (Table 2) (including SAEs and non-SAEs), regardless of their severity,
must be collected and recorded on the AE page of the eCRF.

7.2.1.9 Precautions for AE documentation
Diagnosis, signs, and symptoms
If a diagnosis is already made, the eCRF should record the diagnosis instead of individual
symptoms and signs (such as hepatic failure rather than jaundice, transaminase increased, and
asterixis). However, if the signs and symptoms cannot be attributed to a definitive diagnosis, each
independent event should be documented in the eCRFs as an AE or SAE. Update the report with
visit information if a diagnosis is confirmed later.

AEs secondary to other events
Generally, AEs secondary to other events (such as result of another event or clinical sequelae)
should be documented as the primary event, unless the event is severe or an SAE. However,
clinically significant secondary events should be recorded as independent adverse events in the
eCRFs if they occur at different times than the primary event. If the relationship between events is
unclear, document them as separate events in the eCRFs.
Ongoing or recurrent AEs
An ongoing AE refers to an event that does not resolve and is ongoing between two assessment
time points. These AEs should only be documented once in the eCRFs. The initial severity should
be documented, and the information should be updated if the event exacerbates.
Recurring AEs refer to AE that have resolved between the two time points of assessment but
subsequently occur. These events should be independently documented in the eCRFs.
Abnormalities in laboratory tests/vital signs
Not all abnormalities in laboratory tests/vital signs should be reported as AEs. Only the
abnormalities in laboratory tests/vital signs that meet the following criteria are reported as AEs:

Accompanied with clinical symptoms

Lead to changes in the dose of the study treatment (such as dose adjustment, dose
interruption, or permanent drug withdrawal)

Require medical intervention or changes in concomitant therapy

Judged by the investigator as clinically significant
It is the responsibility of the investigator to review all abnormal laboratory test results and vital
signs, and to determine whether each abnormal laboratory test result or vital signs should be
reported as AEs.
If clinically significant laboratory abnormalities or abnormal vital signs are characteristic of a
disease or syndrome (such as increased levels of alkaline phosphatase and total bilirubin caused by
cholecystitis that are higher than 5 times the upper limit of normal), only the diagnosis is recorded
on the AE report of the eCRF (i.e., cholecystitis). Conversely, the laboratory abnormalities or
abnormal vital signs are recorded on the AE report of the eCRF, and it should be indicated that
whether the test value is above or below the normal range (for example, it should be recorded as
"blood potassium increased" instead of "blood potassium abnormal"). If there is a standard clinical
term corresponding to the laboratory abnormalities or abnormal vital signs, the clinical term should
be recorded on the eCRF (such as "anemia", instead of "hemoglobin decreased"). The same
clinically significant laboratory abnormalities or abnormal vital signs found during multiple
follow-ups should not be repeatedly recorded as AEs or SAEs in the eCRF unless there is a change

in its severity or etiology.
Death
During the entire course of the study, all the deaths that occurred within 90 days after the last dose
were documented in the Death Report Form in the eCRFs and reported to the sponsor timely,
regardless of the causality with the investigational drug.
When recording a death event, if there is an AE leading to the death, a single medical concept
should be used on the AE report of the eCRF to record the event leading to the death, and the event
should be reported as an SAE in an expedited manner; if the cause of the death is unknown at the
time of reporting , "Death with Unknown Cause" should be recorded on the AE report of the eCRF.
The "Death with Unknown Cause" should be reported as an SAE in an expedited manner before
further investigation is carried out to find the exact cause of death.
If the cause of death is confirmed to be PD, then the event should not be documented and reported
as an AE/SAE. However, the event should be documented in the Mortality Report Form of the
eCRF and reported to the sponsor timely.
Pre-existing medical conditions
Symptoms/signs presenting during the screening period will be recorded and reported as AEs only
if their severity, frequency, or property becomes aggravated (except for worsening of the studied
disease). The relative change should be documented, such as "increased frequency of headaches".
Hospitalization and prolonged hospitalization, or surgery
Any AE that results in hospitalization or prolonged hospitalization should be documented and
reported as an SAE, except for the following situations:

Hospitalization or prolonged hospitalization as required by study protocol (such as for dose
administration, efficacy evaluation, etc.)

Hospitalization due to a pre-existing medical condition that remains stable, e.g. elective
surgery/therapy scheduled prior to the study.
However, elective surgery/therapy required because of the exacerbated condition during the study
(e.g. surgery/therapy required earlier than scheduled) should be considered as an AE.
The investigator should fill in all required information, including AE terms
(diagnostic terms, or the record of symptoms and signs including laboratory test abnormalities if
there is no diagnosis), start date, end date, severity level, whether it is an AESI, measures taken for
the investigational product, treatment given for the AE, outcome, seriousness, and relationship with
the investigational product. If the signs and symptoms cannot be attributed to a definitive diagnosis,
each AE should be documented independently.

Progressive disease
For any event, if it can be clearly determined that the event is caused by progressive disease, the
event is not reported as an AE. Hospitalization or death caused by progressive disease does not
need to be reported in an expedited fashion.
Lack of efficacy
When the disease treated by the study treatment deteriorates, it may not be possible to determine
whether it is due to the lack of efficacy or the occurrence of an adverse event. In this case, unless
the investigator believes that the deterioration of the condition is related to the study treatment,
such changes are all regarded as the lack of efficacy rather than adverse events.
Overdose
When there is an accompanying AE, the AE should be recorded; when there is not accompanying
AE, the overdose should be recorded on the eCRF.

8.1 Sample Size Determination
A number of 218 subjects for each group (436 subjects in total) can provide 80% test power to
confirm the clinical equivalence between the treatments of IBI305 in combination with
paclitaxel/carboplatin and bevacizumab in combination with paclitaxel/carboplatin.
The sample size is estimated based on the following assumptions:

The ORRs between IBI305 and bevacizumab group are equivalent

The ORR of subjects in the bevacizumab groups is set to 50.0%

The equivalence margin is taken as (-12.5%, 16.7%)

The significance level of the two one-side test is 0.05

1:1 randomization
Based on the above hypotheses, a number of 218 subjects for each group is required (436
subjects in total). The sample size was estimated using PASS 2013.
8.2 Statistical Population
Intention-to-Treat (ITT): All randomized subjects.
Full Analysis Set (FAS): All randomized subjects who received at least one dose of the study
treatment. This dataset is used as the primary analysis set for efficacy assessment.

8.3 General Principles for Statistical Analyses
For continuous variables, descriptive statistics should include the count, mean, standard
deviation, median, maximum, and minimum. For categorical variables, descriptive statistics will
include the frequency as well as the absolute or relative percentage. Statistical analyses will be
carried out using SAS 9.4.
8.4 Statistical Methods
8.4.1 Adjustments for covariates
Not applicable.
8.4.2 Managing dropouts and missing data
The analyses of primary and secondary endpoints will include data from dropouts. The management
of missing data is described in the Statistical Analysis Plan.
8.4.3 Multi-center study
Since this is a multicenter study, the primary endpoint (ORR) will be listed according to study
sites and treatment groups. However, individual equivalence analysis will not be conducted.
Trial sites with fewer than 5 ITT subjects per treatment group will need to be combined for
analysis. Details will be discussed in the data review meeting.
8.4.4 Multiple comparisons and adjustments to multiplicity
The α adjustment for multiple comparisons is not considered.
8.5 Statistical Analyses
8.5.1 Subject distribution
Refer to Figure 1: Study design schematic for the schedule of activities. The number and
percentage of patients who have completed or dropped out of the study (including the reason for
dropouts such as loss to follow-up, AEs, and poor compliance) are summarized based on
treatment groups.
The number and percentage of subjects in each analysis set are calculated based on treatment groups.
The number and percentage of protocol deviations are calculated based on treatment groups.

8.5.2 Demographics and other baseline characteristics
Demographic information such as age, height, sex, and weight, and other baseline characteristics
such as disease history (including NSCLC diagnosis, staging, previous cancer treatment, and
target and nontarget lesions) are summarized using descriptive statistics.
8.5.3 Compliance and drug exposure
The required dose and the actual dose must be documented in the eCRF. Subject compliance is
calculated based on the ratio of the actual dose (number of doses) to the required dose (number
of doses). Subject compliance is classified into the following categories: < 80%, 80–120%, and >
120%. The number and percentage of subjects in each category will be summarized.
8.5.4 Efficacy
The efficacy analysis will be based on the FAS. Results of the PP set will also be presented.
8.5.4.1 Primary efficacy endpoint
The primary objective of this study is to determine the clinical equivalence between IBI305 +
paclitaxel/carboplatin and bevacizumab + paclitaxel/carboplatin for the treatment of advanced or
relapsed non-squamous non-small cell lung cancer (NSCLC). The primary endpoint is objective
response rate (ORR). ORR is defined as the incidence of patients with confirmed complete
response (CR) or partial response (PR), when a validated imaging method and RECIST v1.1
are used to evaluate target and non-target lesions. Subjects without tumor assessments beyond
baseline will be considered unresponsive to treatment. Subjects qualified for the evaluation of
CR or PR must have at least one measurable lesion according to RECIST v1.1. The evaluation
of clinical equivalence will be based on the ORR provided by the independent review committee
(IRC). Results provided by the investigator will be used for sensitivity analysis.
Clinical equivalence will be declared if the 90% confidence interval of the difference in ORR
between IBI305 and bevacizumab groups falls within the preset margin of (-12.5%, 16.7%).
The ORR and corresponding 95% confidence interval of the two treatment groups, the ORR
difference and the 90% confidence interval, as well as the ORR ratio between the two groups and
the 90% confidence interval will be estimated using the generalized linear model (GLM, which
includes treatment groups and stratification factors).
8.5.4.2 Secondary efficacy endpoints
The secondary endpoints for this study include DOR, DCR, progress-free survival (PFS), and
overall survival (OS).

DCR is defined as the incidence of patients with confirmed complete response (CR), partial
response (PR), and stable disease (SD), when a validated imaging method and RECIST v1.1 are
used to evaluate target and non-target lesions.
DOR is defined as the time from initial tumor response (CR or PR) to PD or death; Subjects with
CR or PR who do not progress or die will be censored on the date of the last tumor assessment.
OS refers to the time from the date of randomization to the date of death (of any cause). For
subjects who are still alive at the time of the analysis, their survival time is censored on the last
known alive date. PFS refers to the time from the date of randomization to the date of first
documented PD or death, whichever occurs first. The investigator will assess PD using RECIST
v1.1. Subjects who do not progress or die will be censored on the date of the last tumor
assessment. Subjects without tumor assessments after baseline are censored on their date of
randomization.
Median OS and its 95% CI will be estimated using the Kaplan-Meier method. The survival curve
will be plotted. The hazard ratio (HR) between the two groups and its 95% CI will be estimated
using a Cox model. The Cox model includes treatment groups and stratification factors. DOR
and PFS will be analyzed using the same method as for OS. DCR will be analyzed using the
same method for primary efficacy endpoints, but an equivalence test will not be conducted.
8.5.4.3 Sensitivity analysis
The center effect (fixed or random) will be considered in the primary and secondary endpoints
analysis models (GLM or Cox).
8.5.4.4 Antibody and efficacy analysis
Subjects who develop antibodies during the clinical study will be summarized in detail. The
difference in efficacy between subjects with and without antibodies will be compared if
necessary.
Changes in PK parameters and steady-state trough concentrations of subjects with positive ADA
are analyzed.
8.5.5 Exploratory analysis
Pharmacodynamic parameters: The changes in the serum VEGF level at different time points are
described, and inter-group comparisons are carried out when necessary (based on the PD dataset)
Steady-state trough concentrations of the drug: The level of trough concentration is described
and inter-group comparisons are carried out when necessary (based on the PPK dataset)

9 QUALITY ASSURANCE AND QUALITY CONTROL
According to GCP principles, the sponsor is responsible for implementing and maintaining
quality assurance and quality control systems based on standard operating procedures (SOP),
to ensure that the implementation of the clinical trial and the collection, documentation, and
reporting of trial data is in accordance with the protocol, GCP, and applicable regulatory
requirements.
To ensure that the data is reliable and processed correctly, there should be quality control for
every step during the data processing.
In addition, the Clinical Quality Assurance (CQA) Department of the sponsor and/or CRO may
conduct regular audits of the study process, including but not limited to auditing the study site,
on-site visits, central laboratory, suppliers, clinical database, and the final clinical study report.
Regulatory authorities may also conduct inspections during the trial or at any time after the trial
is completed. The investigator and the research institution must allow the sponsor's representative
and regulatory authorities to review source data.
9.1 Clinical Monitoring
The sponsor has authorized Wuxi Clinical Co., Ltd. to conduct clinical monitoring for this study.
The clinical research associate (CRA) should follow the SOPs of Wuxi Clinical Co., Ltd. when
carrying out monitoring, and has the same rights and responsibilities as the sponsor's monitor.
The CRA should maintain regular communication with the investigator and the sponsor.
Before the start of the study, the associate monitor assess the qualifications of each study site,
and report issues related to facilities, technical equipment, or medical staff to the sponsor. During
the study, the CRA will be responsible for confirming whether written informed consent is
obtained from all subjects, and whether data documentation is accurate and complete. At the
same time, the CRA will compare data entered in to the eCRF with source data, and notify the
investigator of any errors or omissions. The CRA will also verify protocol compliance of the
study site, as well as the dispensing and storage of investigational drugs to ensure protocol
requirements are met.
The monitoring visit will be conducted in accordance with applicable statutes and regulations.
Each site receives regular monitoring visits from the time the subjects are enrolled. The CRA
should submit a written report to the sponsor after each monitoring visit to the study site.

9.2 Data Management/Coding
The Data Management and Biostatistics Department of Wuxi Clinical Co., Ltd will process data
generated from this study in accordance with relevant SOPs.
This study will use an electronic data capture (EDC) system. Trial data will be entered into the
eCRF by the investigator or authorized study personnel. Prior to launching of the study site or
data entry, the investigator and authorized study personnel will receive appropriate training, and
appropriate safety measures will be taken.
All data are input in Chinese. The eCRF should be completed during or soon after each visit, and
should be constantly updated to ensure that it reflects the latest status of the subject. To avoid
discrepancies in outcome assessments between different evaluators, ensure that baseline and all
subsequent efficacy and safety assessments for the same subject are performed by the same
person. The investigator must review trial data to ensure the accuracy and correctness of all data
entered into the eCRF. During the study, the investigator should document any evaluations that
are not conducted, or any information that is not available, applicable, or known. The
investigator needs to sign all verified data electronically.
The CRA will review the eCRF, and evaluate its completeness and consistency. The CRA will
also compare the eCRF with the source documents to ensure the consistency of critical data. Data
entry, corrections, or modifications are completed by the investigator or designated staff. The
CRA do not have access to data entry. The data in eCRF is submitted to the data server, and any
changes to the data will be documented in the audit trail, including the reason for the change, the
name of the operator, as well as the time and date of the change. The roles and permissions of
study personnel responsible for data entry will be predetermined. The CRA or data manager will
submit data queries in the EDC system, and study personnel shall respond to the queries. The
EDC system will record the audit trail of each query, including the name of the investigator, as
well as the time and date.
Unless otherwise specified, the eCRF should be considered simply as a form for data collection
and not a source document. A source file is used by the investigator or hospital, relevant to the
subject, and can prove the existence of the subject, inclusion criteria, and all records of
participation in the study, including laboratory records, ECG results, memorandum, pharmacy
dispensing records, and subject folders.

The investigators are required to maintain all source documents and to offer the documents to the
CRA for review during each visit. In addition, the investigator must submit a complete eCRF for
each subject, regardless of the duration of the subject's participation in the study. The study
number and subject number in all supporting documents (such as laboratory records or hospital
records) submitted along with the eCRF should be carefully verified. All personal privacy
information (including the name of the subject) should be deleted or be made indecipherable in
order to protect subject privacy.
The investigator could be automatically added to the eCRF with his/her user ID. The investigators
verify that the record have been reviewed and that the data are accurate with an electronic
signature. The electronic signature is completed with the investigator's user ID and password.
The system automatically attaches the date and time of the signature. The investigator could not
share the user ID and password with other personnel. If data in the eCRF need to be modified,
the procedures defined by the EDC system have to be followed. All modifications and reasons
for the changes are recorded in the audit trail.
Training on the EDC system will be provided to study personnel at the study site.
Adverse events, and concurrent diseases/medical history will be coded. The medical dictionary
used for coding will be described in the Clinical Study Report (CSR).
9.3 Audits and Inspections
The sponsor or its representative (WuXi Clinical Co., Ltd) may conduct quality assurance audits
on the study site, database, and relevant study-related documents. Also, regulatory authorities
may also decide to inspect the study site, database, and relevant study-related documents at its
own discretion. The aim of audits and inspections is to systematically and independently check
all study-related procedures and documents to ensure that the clinical study is being carried out
in accordance with requirements of the trial protocol, GCP, Declaration of Helsinki, and
applicable regulations. The investigator must inform the sponsor immediately when an
inspection notice is received from the regulatory authorities.

10 ETHICS
10.1 Independent Ethics Committee
The sponsor and its designated personnel will prepare all documents to be submitted to the
independent ethics committee (IEC) of each study site. The trial protocol, informed consent form
(ICF), investigators brochure, subject recruitment material or advertisements (if applicable), as
well as other documents required by regulations must be submitted to the IEC for approval. Prior
to the start of the study, written approval from the IEC must be obtained and provided to the
sponsor. The IEC approval must clearly state the title, number, and version of the study protocol
as well as the version of other documents (e.g. ICF) and the date of approval. The investigator
must notify the sponsor of the IEC's written comments concerning delays, suspension and re-
approval.
The study site must follow the requirements of the IEC. IEC requirements may include
submitting the revised protocol, ICF, or subject recruitment material to the IEC for approval,
local regulatory requirements for safety reports, and regular reports, updates, and submitting the
final report as per IEC requirements. The above documents as well as the IEC approval must be
provided to the sponsor or its designated personnel.
10.2 Implementation of Ethical Principles
The study process and the acquisition of informed consent should comply with the Declaration of
Helsinki, relevant GCP requirements (CPMP/ICH/135/95), and applicable statutes and
regulations related to drugs and data protection in the country in which the study is conducted.
The GCP is an international ethical and scientific quality standard for designing, conducting,
recording and reporting clinical trials that involve the participation of human subjects. To protect
the rights, safety, and healthy of subjects, this study will be carried out in accordance with GCP
and applicable national regulations, as well as ethical principles outlined in the Declaration of
Helsinki.
The investigator is required to follow the procedures specified in this protocol and must not
change the procedures without the permission from the sponsor. Protocol deviations will be
reported in accordance with the requirements of each ethics committee.

10.3 Subject Information and Informed Consent
Prior to undergoing any study procedure, the ICF should be used to explain to potential participants
the potential risks and benefits of this study. The informed consent form should be in a language
that is simple and be easy to understand. The ICF should state that informed consent is voluntary,
emphasize the potential risks and benefits of participating in this study, and that the subject may
withdraw from the study at any time. The investigator may only enroll a subject after fully
explaining the details of the study, answering questions to the subject's satisfaction, giving
the subject sufficient time for consideration, and obtaining written consent from the subject or
his/her legal representative. All signed ICF must be retained in the investigator's documents or
the subject's folder.
The investigator is responsible for explaining the contents of the ICF and obtaining the ICF
signed and dated by the subject or his/her legal representative prior to starting the study. The
investigator should provide the subject with a copy of the signed ICF. The investigator must
document the informed consent process in the source document of the trial.
10.4 Protection of Subject Data
Information about data protection and privacy protection will be included in the ICF (or in some
cases, in a separate document).
Study personnel must ensure that the privacy of clinical trial subjects are protected. In all
documents submitted to the sponsor, the clinical trial subjects must only be identified with
subject number and not with the full name.
Additional precautions should be taken to ensure the confidentiality of the documents and
to prevent the identification of subjects based on genetic data. However, under special
circumstances, some personnel may be permitted to see the genetic data and personal
identification number of a subject. For example, in the event of a medical emergency, the
sponsor, designated physician, or investigator will have access to the subject identification code
and the subject's genetic data. In addition, regulatory agencies may request access to relevant
documents.

MEASURABILITY OF TUMOR AT BASELINE
1.1
Definitions
At baseline, tumor lesions/lymph nodes will be categorized as measurable or not measurable as
follows:
1.1.1
Measurable
Tumor lesions: must be accurately measured in at least one dimension (longest diameter in the
plane of measurement is to be recorded) with a minimum size of:

10 mm by CT scan (CT scan slice thickness no greater than 5 mm)

10 mm caliper measurement by clinical exam (lesions which cannot be accurately
measured with calipers should be documented as not measurable).

20 mm by chest X-ray.
Malignant lymph nodes: To be considered pathologically enlarged and measurable, a lymph
node must be ≥15 mm in short axis when assessed by CT scan (CT scan slice thickness
recommended to be no greater than 5 mm). At baseline and in follow-up, only the short axis will
be measured and followed.
1.1.2
Not measurable
All other lesions, including small lesions (longest diameter <10 mm or pathological lymph nodes
with a short axis ≥10 and <15 mm) as well as truly not measurable lesions. Lesions considered
truly not measurable include: leptomeningeal disease, ascites, pleural or pericardial effusion,
inflammatory breast disease, lymphangitis involving the skin or lungs, abdominal masses/
abdominal organomegaly identified by physical exam but not measurable by reproducible
imaging techniques.
1.1.3
Special considerations regarding measurable bone lesions, cystic lesions, and lesions
with prior locoregional treatment:
Bone lesions:

Bone scan, PET scan or plain films are not considered adequate imaging
techniques to measure bone lesions. However, these techniques can be used to
confirm the presence or disappearance of bone lesions.


Lytic bone lesions or mixed lytic-blastic lesions, with identifiable soft tissue
components, that can be evaluated by cross sectional imaging techniques (such as
CT or MRI) can be considered as measurable lesions if the soft tissue
components meet the definition of measurability described above.

Blastic bone lesions are not measurable.
Cystic lesions:

Lesions that meet the criteria for radiographically defined simple cysts should not
be considered as malignant lesions (neither measurable nor not measurable) since
they are, by definition, simple cysts.

‘Cystic lesions’ thought to represent cystic metastases can be considered as
measurable lesions, if they meet the definition of measurability described above.
However, if noncystic lesions are present in the same patient, these noncystic
lesions are preferred for selection as target lesions.
Lesions with prior locoregional treatment:

Tumor lesions situated in a previously irradiated area or in an area subjected to
other locoregional therapy are usually not considered measurable, unless there
has been demonstrated progression in the lesion. The study protocol should detail
the conditions under which such lesions would be considered measurable.
1.2
Specifications by Methods of Measurements
1.2.1
Measurement of lesions
All measurements should be documented with metric symbols. Calipers should be used if clinical
assessments are required. All baseline evaluations should be performed as close as possible to
the beginning of the treatment but never more than 4 weeks before the beginning of the treatment.
1.2.2
Method of assessment
The same method of assessment and the same technique should be used to characterize each
identified and reported lesion at baseline and during follow-up. Imaging evaluation should
always be done rather than clinical examination unless the lesion(s) being followed cannot be
imaged but are assessable by clinical examination.
Clinical lesions: Clinical lesions will only be considered measurable when they are superficial
and its diameter is ≥10 mm as assessed using calipers (e.g. skin nodules). For skin lesions,
documentation by color photography including a plotting scale to estimate the size of the lesion
is recommended. As noted above, when lesions can be evaluated by both clinical examination
and imaging evaluation, the latter should be undertaken since it is more objective and may also

be reviewed at the end of the study.
Chest X-ray: Chest CT is preferred over chest X-ray, particularly when progression is an
important endpoint, since CT is more sensitive than X-ray, particularly in identifying new lesions.
However, lesions on chest X-ray may be considered measurable if they have clear boundaries
and are surrounded by aerated lung tissues.
CT and MRI: CT is the best currently available and reproducible method to measure lesions
selected for response assessment. This guideline has defined measurability of lesions on CT scan
based on the assumption that CT slice thickness is 5 mm or less. When CT scans have a slice
thickness greater than 5 mm, the minimum size for a measurable lesion should be twice the slice
thickness. MRI is also acceptable in certain situations (e.g. for body scans).
Ultrasound: Ultrasound should not be used for measuring lesion size and should not be used as
a method of measurement. Ultrasound examinations cannot be reproduced in their entirety for
independent review at a later date and, because they are operator dependent, it cannot be
guaranteed that the same technique and measurements will be taken from one assessment to the
next. If new lesions are identified by ultrasound in the course of the study, confirmation by CT
or MRI is recommended. If there is concern about radiation exposure at CT, MRI may be used
instead of CT in selected instances.
Endoscopy and laparoscopy: The utilization of these techniques is not recommended for
objective tumor evaluation. However, they can be used to confirm complete pathological
response when biopsies are obtained or to determine relapse in trials where recurrence following
complete response or surgical resection is an endpoint.
Tumor markers: Tumor markers alone cannot be used to assess objective tumor response. If
markers are initially above the upper limit of normal, however, they must normalize for a patient
to be considered in complete response. Because tumor markers are disease specific, instructions
for their measurement should be incorporated into the protocol on a disease specific basis.
Specific guidelines for both CA-125 response (in recurrent ovarian cancer) and PSA response
(in recurrent prostate cancer) have been published. In addition, the Gynecologic Cancer
Intergroup has developed CA125 progression criteria which are to be integrated with objective
tumor assessment for use in first-line trials in ovarian cancer.
Cytology and histology: These techniques can be used to differentiate between PR and CR in rare
cases if required by the protocol (for example, residual lesions in tumor types such as seminoma,
where known residual benign tumors can remain). When effusions are known to be a potential
adverse effect of treatment (e.g. with certain taxane compounds or angiogenesis inhibitors),
cytological confirmation of the neoplastic origin of any effusion that appears or worsens during

treatment can be considered if the measurable tumor has met criteria for response or stable
disease in order to differentiate between response (or stable disease) and progressive disease.
2.
TUMOR RESPONSE EVALUATION
2.1
Assessment of Overall Tumor Burden and Measurable Disease
To assess objective response or future progression, it is necessary to estimate the overall tumor
burden at baseline and use this as a comparator for subsequent measurements. Only patients with
measurable disease at baseline should be included in regimens where objective tumor response is
the primary endpoint. Measurable disease is defined by the presence of at least one measurable
lesion. In studies where the primary endpoint is tumor progression (either time to progression or
proportion with progression at a fixed date), the protocol must specify if entry is restricted to
those with measurable disease or whether patients having non-measurable disease only are also
eligible.
2.2
Baseline Documentation of "Target" and "Non-Target" Lesions
When more than one measurable lesion is present at baseline, all lesions (five lesions at most,
and two lesions per organ at most) representative of all involved organs should be identified as
target lesions and will be recorded and measured at baseline (This means in instances where
patients have only one or two organ sites involved, a maximum of two and four lesions
respectively will be recorded).
Target lesions should be selected on the basis of their size (lesions with the longest diameter), be
representative of all involved organs, and should be those with reproducible repeated
measurements. It may be the case that, the largest lesion does not have reproducible
measurements, in which circumstance the next largest lesion with reproducible measurements
should be selected.
Lymph nodes merit special mention since their normal anatomical structures may be visible by
imaging even if not involved by tumor. Pathological nodes which are defined as measurable and
may be identified as target lesions must have a short axis of ≥15 mm by CT scan. Only the short
axis of these nodes will contribute to the baseline sum. The short axis of the node is the diameter
normally used by radiologists to judge if a node is invaded by solid tumor. Nodal size is
normally reported as two dimensions in the plane in which the image is obtained (for CT scan
this is almost always the axial plane; for MRI the plane of acquisition may be axial, sagittal or
coronal). The smaller of these measures is the short axis. For example, an abdominal node which
is reported as being 20 mm × 30 mm has a short axis of 20 mm and qualifies as a malignant
measurable node. In this example, 20 mm should be reported as the node measurement. All other
pathological nodes (those with a short axis ≥10 mm but < 15 mm) should be considered non-

target lesions. Lymph nodes that have a short axis < 10 mm are considered non-pathological and
should not be recorded or followed.
A sum of the diameters (longest for non-nodal lesions; short axis for nodal lesions) for all target
lesions will be calculated and reported as the baseline sum of diameters. If lymph nodes are to be
included in the sum, then as noted above, only the short axis is added into the sum. The baseline
sum of diameters will be used as reference to further characterize any objective tumor regression
in the measurable dimension of the disease.
All other lesions (or sites of disease) including pathological lymph nodes should be identified as
non-target lesions and should also be recorded at baseline. Measurements are not required and
these lesions should be recorded as "present", "absent", or in rare cases "unequivocal
progression". In addition, it is possible to record multiple target lesions involving the same organ
as a single item on the case record form (e.g. ‘multiple enlarged pelvic lymph nodes’ or ‘multiple
liver metastases’).
2.3
Response Criteria
2.3.1
Evaluation of target lesions
Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes
(whether target or non-target) must have a reduced short axis of <10 mm.
Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions vs. the
baseline sum of diameters.
Progressive Disease (PD): At least a 20% increase in the sum of diameters of target lesions vs.
the smallest sum during the study (this includes the baseline sum if that is the smallest). In
addition to the relative increase of 20%, the sum must also have an absolute increase of at least
5 mm. (Note: The appearance of one or more new lesions is also considered progression).
Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to
qualify for PD, using the smallest sum of diameters during the study as reference.
2.3.2
Special notes on the assessment of lymph nodes which are target lesions
Lymph nodes identified as target lesions should always have the actual short axis measurement
recorded (measured in the same anatomical plane as during the baseline examination), even if the
nodes regress to below 10 mm at the time of the study. This means that when lymph nodes are
included as target lesions, the "sum" of lesions may not be zero even if complete response
criteria are met, since a normal lymph node is defined as having a short axis of <10 mm. Case
report forms or other data collection methods may therefore be designed to have target nodal
lesions recorded in a separate section where, in order to qualify for CR, each node must have a

short axis of <10 mm. For PR, SD, and PD, the actual short axis measurement of the nodes is to
be included in the sum of target lesions.
Target lesions that are "too small to measure". During the study, all lesions (nodal and non-
nodal) recorded at baseline should have their actual measurements recorded at each subsequent
evaluation, even when very small (e.g. 2 mm). However, sometimes lesions or lymph nodes
which are recorded as target lesions at baseline become so faint on CT scan that the radiologist
may not feel comfortable assigning an exact measurement and may report them as being "too
small to measure". When this occurs it is important that a value be recorded on the case report
form. If it is the opinion of the radiologist that the lesion has probably disappeared, the
measurement should be recorded as 0 mm. If the lesion is believed to be present and is faintly
seen but too small to measure, a default value of 5 mm should be assigned (Note: It is less likely
that this rule will be used for lymph nodes since they usually have a definable size when normal
and are frequently surrounded by fat such as in the retroperitoneum; however, if a lymph node is
believed to be present and is faintly seen but too small to measure, a default value of 5 mm
should be assigned in this circumstance as well). This default value is derived from the 5 mm CT
slice thickness (but should not be changed with varying CT slice thickness). The measurements
of these lesions are potentially non-reproducible, therefore providing this default value will
prevent false responses or progressions caused by measurement errors. To reiterate, however, if
the radiologist is able to provide an actual measurement, that value should be recorded, even if it
is below 5 mm.
Lesions that split or coalesced at the time of treatment. When non-nodal lesions fragment, the
longest diameters of the fragmented portions should be added together to calculate the target lesion sum.
Similarly, as lesions coalesce, a plane between them may be maintained that would aid in obtaining
maximal diameter measurements of each individual lesion. If the lesions have truly coalesced such that
they are no longer separable, the vector of the longest diameter in this instance should be the maximal
longest diameter for the "coalesced lesion".
2.3.3
Evaluation of non-target lesions
This section provides the definitions of the criteria used to determine the tumor response for the
group of non-target lesions. While some non-target lesions may actually be measurable, they do
not need to be measured and instead should be assessed only qualitatively at the time points
specified in the protocol.
Complete Response (CR): Disappearance of all non-target lesions and normalization of tumor
marker level. All lymph nodes must be non-pathological in size (short axis <10 mm).
Non-CR/Non-PD: Persistence of one or more non-target lesion(s) and/or maintenance of tumor
marker level above the normal limits.

Progressive Disease (PD): Unequivocal progression of existing non-target lesions. (Note: The
appearance of one or more new lesions is also considered progression).
2.3.4
Special notes on the assessment of progression of non-target lesions
The concept of progression of non-target disease requires additional explanation as follows: When
the patient also has measurable lesions. In this setting, to achieve ‘unequivocal progression’ on the
basis of the non-target lesion, there must be an overall level of substantial worsening in non-target
disease such that, even in the presence of SD or PR of the target disease, the overall tumor burden
has increased sufficiently to merit discontinuation of therapy. A minimal increase in the size of one
or more non-target lesions is usually not sufficient to quality for unequivocal progression status.
The designation of overall progression solely on the basis of change in non-target lesions in the
face of SD or PR of target disease will therefore be extremely rare.
When the patient has only lesions that are not measurable. This circumstance arises in some
phase III trials when the presence of measurable lesions is not a criterion for study enrollment.
The same general concepts apply here as well. However, in this instance there are no measurable
lesions to factor into the interpretation of an increase in non-measurable lesion burden. Because
worsening in non-target lesion cannot be easily quantified (by definition: if all lesions are truly
not measurable), a useful test that can be applied when assessing patients for unequivocal
progression is to consider if the increase in overall lesion burden based on the change in non-
measurable disease is comparable in magnitude to the increase that would be required to declare
PD for measurable disease: i.e. an increase in tumor burden representing an additional 73%
increase in volume (which is equivalent to a 20% increase of diameter in a measurable lesion).
Examples include an increase in pleural effusion from "trace" to "large amount", an increase in
lymphangitic lesion from localized to widespread, or a description in the protocol such as
"sufficient to require a change in therapy". If ‘unequivocal progression’ is seen, the patient
should be considered to have had overall PD at that point. While it would be ideal to have
objective criteria to apply to diseases that are not measurable, the very nature of these diseases
makes it impossible to do so, therefore the increase must be substantial.
2.3.5
New lesions
The appearance of new malignant lesions denotes disease progression; therefore, some
comments on the detection of new lesions are important. There are no specific criteria for the
identification of new radiographic lesions; however, the finding of a new lesion should be
unequivocal: i.e. not attributable to differences in scanning technique, change in imaging
modality or findings thought to represent something other than tumors (for example, some new
bone lesions which may be simply healed or flare of pre-existing lesions). This is particularly

Confidential
important when the patient’s baseline lesions show partial or complete response. For example,
necrosis of a liver lesion may be reported by a CT scan as a "new" cystic lesion, while it is
actually not.
A lesion identified during a follow-up in an anatomical location that is not discovered during the
baseline scan is considered a new lesion and will indicate disease progression. For example, a
patient with a visceral disease at baseline has a brain CT or MRI which reveals metastases. The
patient's brain metastases are considered evidence of PD even if he/she does not have brain
imaging at baseline.
If a new lesion is equivocal, for example because of its small size, continued therapy and follow-
up evaluation will clarify if it represents a truly new lesion. If repeat scans confirm there is
definitely a new lesion, then progression should be declared using the date of the initial scan.
While FDG-PET response assessments need additional studies, it is sometimes reasonable to
incorporate the use of FDG-PET scanning to complement CT scanning in assessment of
progression (particularly possible "new" lesions). New lesions on the basis of FDG-PET imaging
can be identified as follows:
a.
A negative FDG-PET at baseline and a positive FDG-PET at follow-up is a sign of PD
based on a new lesion.
b.
No FDG-PET at baseline and a positive FDG-PET at follow-up:
If the positive FDG-PET at follow-up corresponds to a new lesion site confirmed by
CT, this is PD. If the positive FDG-PET at follow-up is not confirmed as a new lesion
site on CT, additional follow-up CT scans are needed to determine if there is truly
progression at that site (if so, the date of PD will be the date of the initial abnormal
FDG-PET scan). If the positive FDG-PET at follow-up corresponds to a pre-existing
lesion site on CT that is not progressing according to the anatomic images, this is not PD.
2.4
Evaluation of Best Overall Response
The best overall response is the best response recorded from the start of the study treatment until
the end of treatment, taking into account any requirement for confirmation. On occasion a
response may not be documented until after the end of therapy, so the study protocol should
clearly state if post-treatment assessments are to be considered when determining best overall
response. The study protocol must specify how any new therapy introduced before progression
will affect best response designation. Assignment of best overall response for the patient will
depend on the findings of both target and non-target lesions and will also take into consideration
the appearance of new lesions. Furthermore, depending on the nature of the study and the

protocol requirements, confirmatory measurement may also be required. Specifically, in non-
randomized trials where response is the primary endpoint, confirmation of PR or CR is needed to
determine which one is the "best overall response".
2.4.1
Time point response
It is assumed that at each time point specified by the study protocol, a response assessment
occurs. Table 1 on the next page provides a summary of the overall response status calculation at
each time point for patients who have measurable disease at baseline.
When patients have non-measurable (therefore non-target) disease only, Table 2 is to be used.
2.4.2
Missing assessments and non-evaluable targets
When no imaging/measurement is done at a particular time point, the patient is not evaluable
(NE) at that time point. If only a subset of lesion measurements is made at an assessment, usually
the case is also considered NE at that time point, unless a convincing argument can be made that
the missing lesion(s) would not change the response at the assigned time point. This would be
most likely to happen in the case of PD. For example, if a patient has a baseline sum of 50 mm
with three measured lesions and at follow-up only two lesions are assessed and with a sum of 80
mm, the patient will have achieved PD status, regardless of the contribution of the missing lesion.
2.4.3
Best overall response: all time points
The best response is determined once all the data for the patient is obtained.
Best response determination in trials where confirmation of complete or partial response is not
required: Best response in these trials is defined as the best response across all time points (for
example, the best overall response of a patient who has SD at the first assessment, PR at the
second, and PD at the last is PR). When SD is believed to be best response, it must also meet the
minimum time from baseline specified by the protocol. If the minimum time is not met,
otherwise SD is the best time point response, the patient’s best response depends on subsequent
assessments. For example, if a patient has SD at the first assessment, PD at the second and does
not meet the minimum duration for SD, his/her best response is PD. The same patient lost to
follow-up after the first SD assessment would be considered not evaluable.
Best response determination in trials where confirmation of complete or partial response is
required: Complete or partial responses may be claimed only if the criteria for each are met at a
subsequent time point specified in the protocol (generally 4 weeks later). In this circumstance,
the best overall response can be interpreted as in Table 3.

2.4.4
Special notes on response assessment
When nodal lesions are included in the sum of target lesions and the nodes decrease to "normal"
size (<10 mm), they may still have a measurement reported on scans. This measurement should
be recorded even if the nodes are normal in size in order not to overstate progression should it be
based on the increase in size of the nodes. As noted earlier, this means that patients with CR may
not have a total sum of "zero" on the case report form (CRF).
In trials where confirmation of response is required, repeated "NE" time point assessments may
complicate best response determination. The analysis plan for the trial must explain how missing
data/assessments will be addressed in the determination of response and progression. For
example, in most trials it is reasonable to consider a patient with time point responses of PR-NE-
PR as a confirmed response.
Patients with a global deterioration of health status requiring discontinuation of treatment without
objective evidence of disease progression at that time should be reported as "symptomatic
deterioration". Every effort should be made to document objective progression even after
discontinuation of treatment. Symptomatic deterioration is not a descriptor of an objective
response. Instead, it is a reason for stopping the study treatment. The objective response status of
this type of patients is to be determined by evaluation of target and non-target lesions as shown
in Table 1–3.
Conditions that define "early progression, early death, and non-evaluability" are study specific
and should be clearly described in each study protocol (depending on treatment duration and
treatment periodicity).
In some circumstances it may be difficult to distinguish a residual lesion from normal tissues.
When the evaluation of complete response depends upon this determination, it is recommended
that the residual lesion be investigated (by fine needle aspirate/biopsy) before assigning a status
of complete response.
Like a biopsy, FDG-PET may also be used to upgrade a response to a CR in cases where a
residual radiographic abnormality is thought to represent fibrosis or scarring. The use of FDG-
PET in this circumstance should be pre-defined in the protocol and supported by disease specific
medical literature for the indication. However, it must be acknowledged that both approaches
may lead to false positive CR due to limitations of FDG-PET and biopsy resolution/sensitivity.

a "Non-CR/non-PD" is preferred over "stable disease" for non-target disease, since SD is increasingly used as an
endpoint for assessment of efficacy in some trials, thus assigning this category in the absence of measurable
lesions is not advised.
For equivocal findings of progression (e.g. very small and uncertain new lesions; cystic changes
or necrosis in existing lesions), treatment may continue until the next scheduled assessment. If at
the next scheduled assessment, progression is confirmed, the date of progression should be the
earlier date when progression is suspected.

a If CR is truly achieved at the first time point, then any lesions seen at a subsequent time point, even those meeting
PR criteria relative to baseline, make the disease PD at that time point (since lesions must have reappeared after
CR). Best response would depend on whether the minimum duration for SD is met. However, sometimes CR may
be claimed and subsequent scans suggest small lesions are likely still present, while in fact the patient have PR
instead of CR at the first time point. Under these circumstances, CR should be changed to PR and the best response
is PR.
2.5 Frequency of Tumor Re-Evaluation
Frequency of tumor re-evaluation during treatment should be protocol specific and adapted to the
type and schedule of treatment. However, for phase II studies where the beneficial effect of the
treatment is not known, follow-up every 6–8 weeks (timed to coincide with the end of a cycle) is
reasonable. Smaller or greater time intervals may be justified for certain regimens or circumstances.
The study protocol should specify which organ sites are to be evaluated at baseline (usually those
most likely to be involved with metastatic disease for the tumor type under study) and how
often evaluations are repeated. Normally, all target and non-target sites are evaluated at each
assessment. Under certain circumstances, some non-target organs may be evaluated less frequently.
For example, bone scans may need to be repeated only when complete response is identified in
the target lesion or when progression is suspected.

After the end of the treatment, the need for repeated tumor evaluations depends on whether the
trial has a goal such as a certain response rate or a certain time to an event (progression/death).
If ‘time to an event’ (e.g. time to progression, disease-free survival, progression-free survival) is
the main endpoint of the study, then routine scheduled re-evaluation of lesion sites specified by
the protocol must be carried out. In randomized comparative trials in particular, the scheduled
assessments should be performed on time (for example: every 6–8 weeks during the treatment or
every 3–4 months after the treatment) and should not be affected by treatment delays, holidays or
any other events that might lead to imbalance in the timing of disease assessment between
treatment arms.
2.6 Confirmation of Measurements/Duration of Response
2.6.1 Confirmation
In non-randomized trials where response is the primary endpoint, confirmation of PR and CR is
required to ensure responses identified are not the result of measurement errors. This will also
permit appropriate interpretation of results in the context of historical data. Response
confirmation has been traditionally required in such trials. However, in all other circumstances,
i.e. in randomized trials (phase II or III) or studies where stable disease or progression are the
primary endpoints, confirmation of response is not required since it will not add value to the
interpretation of trial results. However, elimination of the requirement for response confirmation
may increase the importance of central review to protect against bias, in particular in studies
which are not blinded.
In the case of SD, measurements after study entry must have met the minimum interval for SD
(generally not shorter than 6–8 weeks) defined in the study protocol at least once.
2.6.2 Duration of overall response
The duration of overall response is measured from the time CR/PR measurement criteria are first
met CR/PR (whichever is first documented) until the date when recurrent or progressive disease
is objectively documented for the first time (using the shortest time to progressive disease
documented during the study as reference).
The duration of overall complete response is measured from the time CR measurement criteria
are first met until the date when recurrent disease is objectively documented for the first time.
2.6.3 Duration of stable disease
Stable disease is measured from the start of the treatment (in randomized trials, from the date
of randomization) until the criteria for progression are met, using the smallest sum during the
study as reference (if the baseline sum is the smallest, then it is used as the reference for the
calculation of PD).

The clinical relevance of the duration of stable disease varies with different studies and diseases.
If the proportion of patients achieving stable disease for a minimum period of time is an endpoint
of importance in a particular trial, the protocol should specify the minimal time interval required
between two measurements for the determination of stable disease.
Note: The duration of response and stable disease as well as the progression-free survival are
influenced by the frequency of follow-up after baseline evaluation. It is not in the scope of the
guidelines to define a standard follow-up frequency. The frequency should take into account
many parameters including disease types and stages, treatment periodicity, and standard practice.
However, limitations of the precision of the measured endpoint should be taken into account if
comparisons between trials are to be made.

P8：Sample size calculation:
A number of 200 subjects for each group (400 subjects in total)
will provide over 80% power to confirm the clinical equivalence
between IBI305 plus paclitaxel/carboplatin and bevacizumab
plus paclitaxel/carboplatin. Estimation of sample size: If the
significance level of the two one-sided test is 0.05, the ORR
between IBI305 and bevacizumab group is about 54.4%, with an
equivalence margin of (-15%, 15%). Based on the above
assumptions, 189 subjects are required for each group (378
subjects in total). The sample size is expanded to 200 subjects
for each group (400 subjects in total) after taking dropouts into
consideration.
A number of 218 subjects for each group (436 subjects in total)
can provide 80% test power to confirm the clinical equivalence
between the treatments of IBI305 in combination with
paclitaxel/carboplatin and bevacizumab in combination with
paclitaxel/carboplatin. Estimation parameters for sample size:
The significance level of the two-sided test is 0.05, the ORR of
subjects in the IBI305 and bevacizumab groups is about 50.0%,
and the equivalence margin is taken as (-12.5%, 16.7%). Based on

P53 Adverse events
An adverse event is defined as any untoward medical occurrence
suffered by the subject of the clinical research, which does not
necessarily have a causal relationship with the treatment. An
adverse event can therefore be any unfavorable and unintended
sign (including an abnormal laboratory finding), symptom, or
disease temporally associated with the use of the investigational
drug, whether or not considered related to the investigational
drug
An AE refers to any untoward medical occurrence in a subject
after signing the informed consent form, and does not necessarily
have a causal relationship with the treatment. Thus, an AE can be
any unfavorable and unintended sign (including an abnormal
laboratory finding), symptom, or disease, whether considered
drug related.
Abnormalities resulting from PD are not considered as AEs.

(2) Is life-threatening (The term "life-threatening" refers to an
event in which the subject is at risk of death at the time of the
event; it does not refer to an event which hypothetically might
have caused death if it is more severe).
(3) Requires inpatient hospitalization or prolongation of existing
hospitalization: This does not include hospitalization and/or
surgical procedures scheduled to be conducted prior to or during
the study for a disease or disorder that exists prior to study
enrollment and has not worsened during the course of the study.

necessarily result in death, are not life-threatening, and do not
require hospitalization, but may jeopardize the subject and may
require medical or surgical intervention to prevent one of the
aboves outcomes, are also considered SAEs.
Note: Hospitalization as a result of PD is not considered an
SAE.
Other Definitions
An adverse drug reaction (ADR) refers to any untoward
response related to the investigational drug after receiving any
the time, but does not include the case that may lead to
death only when the event worsens).

excluding an emergency or outpatient visit. Subjects
with existing diseases or conditions prior to the

An unexpected adverse drug reaction is any adverse reaction that
is not consistent with information known about the
investigational drug.
P53 Severity of adverse events
The severity of AEs will be assessed by CTCAE 4.03. The
classifications are as follows:

Grade 1 Mild; asymptomatic or mild symptoms;
clinical or diagnostic observations only; intervention
not indicated.

Grade 2 Moderate; minimal, local or noninvasive
intervention indicated; limiting age-appropriate
instrumental ADL (e.g. preparing meals, shopping for
groceries or clothes, using the telephone, managing
money, etc.)

Grade 3 Severe or medically significant but not
immediately life-threatening; hospitalization or
prolongation of hospitalization indicated; disabling;
limiting self care ADL (e.g. bathing, dressing and
undressing, feeding oneself, using the toilet, taking
medications, and not bedridden)
The severity of AEs is evaluated using the 5-level criteria of NCI
CTCAE v4.03.
For AEs not included in CTCAE v4.03, use the following CTCAE
general guidelines:

Grade 1: Mild; asymptomatic or mild signs; clinical or
diagnostic observations only; medical intervention not
indicated.

Grade 2: Moderate; minimal/local or noninvasive
intervention indicated; limiting age-appropriate
instrumental activities of daily life (such as cooking,
shopping, using the phone, financial management, etc.).

Precautions for AE documentation
Diagnosis, signs, and symptoms
If a diagnosis is already made, the eCRF should record the
diagnosis instead of individual symptoms and signs
(such as hepatic failure rather than jaundice, transaminase
increased, and asterixis). However, if the signs and symptoms
cannot
be
attributed
to
a
definitive
diagnosis,
each
independent event should be documented in the eCRFs as an
AE or SAE. Update the report with visit information if a
diagnosis is confirmed later.
AEs secondary to other events
Generally, AEs secondary to other events (such as result of
another event or clinical sequelae)
should be documented as the primary event, unless the event
is severe or an SAE. However, clinically significant secondary
events should be recorded as independent adverse events in
the eCRFs if they occur at different times than the primary
event. If the relationship between events is unclear, document
them as separate events in the eCRFs.

Ongoing or recurrent AEs
An ongoing AE refers to an event that does not resolve
and is ongoing between two assessment time points. These AEs
should only be documented once in the eCRFs. The initial
severity should be documented, and the information should be
updated if the event exacerbates.
Recurring AEs refer to AE that have resolved between the two
time points of
assessment but subsequently occur. These events should be
independently documented in the eCRFs.
Abnormalities in laboratory tests/vital signs
Not all abnormalities in laboratory tests/vital signs should be
reported as AEs. Only the abnormalities in laboratory
tests/vital signs that meet the following criteria are reported as
AEs:

Accompanied with clinical symptoms

Lead to changes in the dose of the study treatment
(such as dose adjustment, dose interruption, or
permanent drug withdrawal)

Judged by the investigator as clinically significant
It is the responsibility of the investigator to review all
abnormal laboratory test results and vital signs, and to
determine whether each abnormal laboratory test result or
vital signs should be reported as AEs.
If clinically significant laboratory abnormalities or abnormal
vital signs are characteristic of a disease or syndrome (such as
increased levels of alkaline phosphatase and total bilirubin
caused by cholecystitis that are higher than 5 times the upper
limit of normal), only the diagnosis is recorded on the AE
report
of the eCRF (i.e., cholecystitis). Conversely, the
laboratory abnormalities or abnormal vital signs are recorded
on the AE report of the eCRF, and it should be indicated that
whether the test value is above or below the normal range (for
example,
it
should
be
recorded
as
"blood
potassium
increased" instead of "blood potassium abnormal"). If there is
a standard clinical term corresponding to the laboratory
abnormalities or abnormal vital signs, the clinical term should
be recorded on the eCRF
(such as "anemia", instead of "hemoglobin decreased"). The
same
clinically
significant
laboratory
abnormalities
or
abnormal vital signs found during multiple follow-ups should
not be repeatedly recorded as AEs or SAEs in the eCRF unless

Death
During the entire course of the study, all the deaths that
occurred within 90 days after the last dose were documented

regardless
of
the
causality
with

investigational drug.
When recording a death event, if there is an AE leading to the
death, a single medical concept should be used on the AE
report of the eCRF to record the event leading to the death,
and the event should be reported as an SAE in an expedited
manner; if the cause of the death is unknown at the time of
reporting , "Death with Unknown Cause" should be recorded
on the AE report of the eCRF. The "Death with Unknown
Cause" should be reported as an SAE in an expedited manner
before further investigation is carried out to find the exact
cause of death.
If the cause of death is confirmed to be PD, then the event
should not be documented and reported as an AE/SAE.
However, the event should be documented in the Mortality
Report Form of the eCRF and reported to the sponsor timely.

Hospitalization and prolonged hospitalization, or surgery
Any


Hospitalization or prolonged hospitalization as
required by study protocol (such as for dose

condition that remains stable, e.g. elective
surgery/therapy scheduled prior to the study.

For any event, if it can be clearly determined that the event is

AE. Hospitalization or death caused by progressive disease
does not need to be reported in an expedited fashion.
Lack of Efficacy
When the disease treated by the study treatment deteriorates,
it may not be possible to determine whether it is due to the
lack of efficacy or the occurrence of an adverse event. In this
case, unless the investigator believes that the deterioration of
the condition is related to the study treatment, such changes
are all regarded as the lack of efficacy rather than adverse
events.

It will require 200 subjects in each treatment group (400 in total)
to demonstrate clinical equivalence between IBI305 +
paclitaxel/carboplatin and bevacizumab + paclitaxel/carboplatin
with more than 80% power.
The sample size is estimated based on the following
assumptions:

The actual difference in ORR between subjects in the
IBI305 and bevacizumab arms is 0

The ORR of subjects in the bevacizumab arm is about
54.4%

The equivalence margin is (-15%, 15%)

The significance level of the two one-side test is 0.05

1:1 randomization
Based on the above assumptions, 189 subjects are required for
each treatment group (378 in total). The sample size is expanded
to 200 subjects for each treatment group (400 in total) after
taking dropouts into consideration. The sample size was
estimated using PASS 2013.

Study design:
This is a randomized, double-blinded, multi-center phase III study. The study planned to enroll and randomize
400 subjects with non-squamous NSCLC in a 1:1 ratio to IBI305 plus paclitaxel/carboplatin group or bevacizumab
plus paclitaxel/carboplatin group. Stratifying factors include age (< 60 vs. ≥60 years old) and EGFR status (wild
type vs. mutant).
Each treatment cycle is 3 weeks for both groups. 15 mg/kg IBI305 or bevacizumab is administered on D1 of each
cycle along with paclitaxel/carboplatin. Subjects will receive up to 6 treatment cycles of combination therapy until
PD, unacceptable toxicity, withdrawal of informed consent, loss to follow-up, or death (whichever comes first).
Then subjects receive monotherapy, that is, discontinuing paclitaxel/carboplatin while continuing therapy with
IBI305 or bevacizumab. The monotherapy continues every 3 weeks. On D1 of each treatment cycle, subjects will be
administered 7.5 mg/kg of either IBI305 or bevacizumab until PD, unacceptable toxicity, withdrawal of informed
consent, loss to follow-up, death, or end of study (whichever comes first).
During the study, a CT or an MRI will be performed every 6 weeks (± 7 days) and be determined whether the study
treatment will be continued by investigators at each site through tumor assessments until PD, withdrawal of
informed consent, lost to follow-up, death, start of other anti-tumor therapies, or end of study. If subjects discontinue
the study treatment for reasons other than PD, tumor assessments will be continued until PD, withdrawal of
informed consent, loss of follow-up, death, start of other anti-tumor therapies, or end of study. If subjects discontinue
the study treatment for PD, the investigators will make telephone follow-up every 12 weeks (± 7 days) to collect
information of subsequent anti-tumor therapies and survival until withdrawal of informed consent, lost to follow-up,
death, or end of study.

Statistical methods:
Sample size calculation:
A number of 200 subjects for each group (400 subjects in total) will provide over 80% power to confirm the clinical
equivalence between IBI305 plus paclitaxel/carboplatin and bevacizumab plus paclitaxel/carboplatin. Estimation of
sample size: If the significance level of the two one-sided test is 0.05, the ORR between IBI305 and bevacizumab
group is about 54.4%, with an equivalence margin of (-15%, 15%). Based on the above assumptions, 189 subjects
are required for each group (378 subjects in total). The sample size is expanded to 200 subjects for each group
(400 subjects in total) after taking dropouts into consideration.
Efficacy analysis:
Clinical equivalence will be determined by whether the 90% confidence interval (CI) of the difference in ORR
between the IBI305 and bevacizumab arms falls within the preset margin of (-15% to 15%). The ORR and 95% CI
of two groups, ORR difference and 90% CI, and ORR ratio and 90% CI will be estimated using the generalized
linear model (GLM, including groups and stratification factors).

Median survival (OS) and survival curves will be estimated using the Kaplan-Meier method. The hazard ratio (HR)
and 95% CI of two groups will be estimated using the Cox model. DORs and PFSs will be analyzed by the same
method as the median survivals. DCR will be analyzed using the same method for primary efficacy endpoints, but
an equivalence test will not be conducted.
Safety analysis:
All adverse events (AE) will be coded using MedDRA and graded according to CTCAE v4.03. All treatment-
emergent adverse events (TEAEs), Grade 3 or greater TEAEs, serious adverse events (SAEs), investigational drug-
related TEAEs, investigational drug-related SAEs, TEAEs leading to treatment discontinuation, TEAEs leading
to study termination, and adverse events of special interest (AESIs) will be listed based on system organ class,
preferred terms, and groups and the numbers of corresponding subjects and percentages will be summarized.
In addition, the severity of TEAEs and the correlation with the study drug will also be summarized by system
organ class, preferred terms, and treatment groups.
Measured values and changes from baseline for vital signs, physical examination, laboratory tests and 12-lead ECG
will be analyzed using descriptive statistics. Baseline results and worst results during the study will be presented in
cross tabulation.
The number and percentage of subjects who developed anti-drug antibodies and neutralizing antibodies during the
study will be summarized by treatment group.

1 INTRODUCTION
1.1 Study Background
1.1.1 Disease background
Lung cancer has the highest incidence and mortality globally among all cancers. According to
the 2012 Global Cancer Statistics (GLOBOCAN 2012) published by International Agency for
Research on Cancer, there were approximately 1.8 million new lung cancer cases worldwide,
which accounted for 13% of the global newly-diagnosed cancers, and 58% of these cases
occurred in underdeveloped areas1. According to the data released by the National Central
Cancer Registry of China in 2015, lung cancer was the most prevalent malignancy in China in
2011, with about 650,000 new cases every year. Lung cancer was also the leading cause of death,
with about 520,000 deaths per year2. The limited clinical treatment of lung cancer is the main
reason for its poor prognosis. There is a huge demand for new types of lung cancer treatment
drugs.
Approximately 85–90% of lung cancers are non-small cell lung cancer (NSCLC) and patients
with NSCLC are usually in the advanced stages when diagnosed3. According to the Chinese
guidelines for the diagnosis and treatment of primary lung cancer, anatomic pulmonary resection
is the mainstay of treatment for early stage lung cancers4. However, despite surgery, some
patients develop distance metastases that eventually lead to death5. Surgery is not possible for
most patients with clearly diagnosed stage IIIb and IV as well as some patients with stage IIIa
NSCLC4. Comprehensive treatment based on systemic therapy is used to maximize patient
survival, control progressive disease, and improve the quality of life6.
In recent years, anti-tumor therapies have entered a new era with the emergency of targeted
drugs. Some of these targeted drugs have demonstrated satisfactory efficacy in the treatment of
advanced NSCLC. These targeted drugs include monoclonal antibodies and tyrosine kinase
inhibitors (TKIs), mostly targeting epidermal growth factor receptors (EGFRs) and vascular
endothelial growth factor (VEGF), such as bevacizumab, cetuximab, gefitinib, erlotinib, and
icotinib. Monoclonal antibodies have become the drugs of choice in various treatment guidelines
due to the good targeting ability, low drug resistance, and good patient tolerability. Bevacizumab
combination chemotherapy is a first-line therapy of NSCLC recommended by the National
Comprehensive Cancer Network (NCCN)7. Additionally, bevacizumab in combination with
paclitaxel/carboplatin has also been approved as the first-line therapy of unresectable advanced,
metastatic, or relapsed non-squamous NSCLC by China Food and Drug Administration (CFDA)
on Jul. 9, 20156.

Compared with traditional chemotherapy that directly inhibit or kill tumor cells, anti-angiogenic
drugs have the following unique advantages8:

The targets are genetically stable vascular endothelial cells (VECs) rather than highly
heterogeneous tumor cells, thus leading to lower drug resistance;

The number of tumor-induced VECs is far less than that of tumor cells, and the efficacy
is preferable targeting on VECs and their cytokines;

Normal VECs are quiescent, whereas tumor VECs are active in proliferation. Anti-
angiogenic therapy targets activated cells and avoids damage to normal VECs, thus
leading to better targeting ability;

Anti-angiogenic therapy can normalize the tumor vessels and thereby reduce the
pressure in tumor tissues. This enhances the delivery of chemotherapeutic agents into
tumor tissues, thus increasing the efficacy of chemotherapy.
Angiogenesis is a basic biological characteristic of tumors. The growth of both solid and
hematologic tumors are depended on angiogenesis regardless of the nature of tumor cells.
Therefore, anti-angiogenic therapy is broad-spectrum and applicable to various tumors.
Bevacizumab is a recombinant humanized monoclonal antibody that selectively binds to human
VEGF and blocks its biological activity. Bevacizumab consists of a framework region of a
human antibody and a humanized murine antigen binding region that can inhibit the binding of
VEGF to its receptors on epithelial cells, Flt-1 and KDR. By blocking the activity of VEGF and
reducing tumor angiogenesis, tumor growth is inhibited9.
In a study conducted by the Estern Cooperative Oncology Group (ECOG), compared with
chemotherapy alone (paclitaxel/ carboplatin), bevacizumab in combination with paclitaxel/carboplatin
significantly increased the overall survival (OS) (median: 12.3 vs. 10.3 months), progression-free
survival (PFS) (median: 6.2 vs. 4.5 months), and overall response rate (ORR) (35% vs. 15%) in
patients with advanced, metastatic, or relapsed non-squamous NSCLC10. In another foreign
AVAiL study, different doses of bevacizumab (7 and 15 mg/kg) in combination with
chemotherapy (cisplatin and gemcitabine) and placebo combine with chemotherapy were
compared for the treatment of non-squamous NSCLC. The study found that the two
bevacizumab groups had significantly increased the PFS (median: 6.7 months (7.5 mg/kg
combination chemotherapy group) vs. 6.5 months (15 mg/kg combination chemotherapy group)
vs. 6.1 months (placebo combination chemotherapy group)) and the ORR (37.8% (7.5 mg/kg
combination chemotherapy group) vs. 34.6% (15 mg/kg combination chemotherapy group) vs.
21.6% (placebo combination chemotherapy group)) in patients with locally advanced, metastatic,
or relapsed non-squamous NSCLC11. In a BEYOND study conducted in China, compared with

placebo in combination with paclitaxel/carboplatin, bevacizumab in combination with
paclitaxel/carboplatin significantly increase the PFS (median: 9.2 vs. 6.5 months), OS (median:
24.3 vs. 17.7 months), and the ORR (54% vs. 26%) in patients with advanced or relapsed non-
squamous NSCLC12.
In China, the antibodies and fusion proteins targeting VEGF are research hotspots. However,
since 2006, the clinical efficacies of various drugs has not been verified and no products have
been marketed. Considering the complexity of macromolecular drugs and the limitations of drug
development capability in China, advanced technologies in antibody development, production,
and quality control is required to develop high-quality VEGF inhibitors that are safe and
effective. IBI305 has showed high similarity to bevacizumab in various pharmaceutical and
nonclinical studies (refer to Investigator's Brochure [IB]). Besides, the efficacy and safety of
bevacizumab for treatment of locally advanced, metastatic or relapsed lung cancer have been
verified. The relevant domestice and external pivotal clinical studies are referable for the
protocol design of IBI305 clinical study. In summary, the clinical study of IBI305 for treatment
of NSCLC has a solid foundation and relatively low risks. The successful development of IBI305
indicates an additional first-line targeted drug for lung cancer in China, providing doctors and
patients with more therapeutic options.
1.1.2 Investigational drug
1.1.2.1 Description of investigational drug
IBI305 is a recombinant humanized anti-VEGF monoclonal antibody injection developed by
Innovent Biologics (Suzhou) Co., Ltd. (hereafter as sponsor) that specifically binds human
VEGF. The molecular weight of IBI305 is 149 KDa. IBI305 specifically binds to VEGF-A,
inhibits the binding of VEGF-A to VEGF-R1 and VEGF-R2, blocks the signaling pathways such
as PI3K/Akt/PKB and Ras-Raf-MEK-ERK. IBI305 also inhibits the growth, proliferation, and
migration of VECs and angiogenesis, decreases the vascular permeability, blocks blood supply to
tumor tissues, inhibits the proliferation and metastasis of tumor cells, and induces the apoptosis
of tumor cells, thereby generates anti-tumor effects. The main active ingredient is recombinant
humanized anti-VEGF monoclonal antibody and excipients include sodium acetate, sorbitol, and
polysorbate 8013. Refer to the Investigator's Brochure for the detailed structure and
physicochemical properties of IBI305.

1.1.2.2 Preclinical studies
Pharmaceutical studies
The pharmaceutical studies showed that stability, primary structure, higher-order structure,
oligosaccharide distribution, charge variant, and product-related impurities of IBI305 are highly
similar to those of bevacizumab, and the process-related impurities meet the proposed
specification. Therefore, IBI305 is considered to have highly similar protein properties and
product quality to bevacizumab13.
Pharmacodynamic studies
In vitro and in vivo pharmacodynamic (PD) studies of IBI305 showed the following findings:
1)
Target: IBI305 displayed specifically high-affinity binding to recombinant human
VEGF-A with an affinity constant same as that of bevacizumab, indicating that IBI305,
the same as bevacizumab, is a specific human VEGF blocker with a clear target.
2)
Specificity: IBI305 displayed specifically high-affinity binding to recombinant human
VEGF-A, medium-affinity binding to canine VEGF-A, but low-affinity binding to
human VEGF-B, VEGF-C, VEGF-D, PlGF, suggesting that IBI305 recognizes specific
targets and has low off-target toxicity risk; no obvious affinity to mouse VEGF-A164
and rat VEGF-A164, suggesting that IBI305 has high species specificity.
3)
Mechanism of action: IBI305 specifically binds to VEGF-A and inhibits the activation
of VEGFR-2 and ERK1/2, blocks the proliferation and migration of HUVEC, and
inhibits the sprouting from rat aortic ring, suggesting that IBI305 antagonizes VEGF-
A-induced signaling pathway to block the proliferation and migration of VECs and
inhibit angiogenesis, which leads to the reduction of nutritional supply and metastasis
of tumor.
4)
Anti-tumor effects: IBI305 significantly inhibits the growth of human colon cancer
Ls174t and lung cancer NCI-H460 cells in xenografts in nude mice, indicating that
IBI305 has significant anti-tumor effects.
Results from in vitro and in vivo studies of IBI305 showed highly similarity with that of
bevacizumab designed simultaneously, demonstrating that the target, mechanism of action,
and anti-tumor effects of IBI305 are highly similar to bevacizumab13.

Pharmacokinetic studies
In vitro and in vivo pharmacokinetic (PK) studies of IBI305 showed the following findings:
1)
IBI305 showed no significant cross-reactivity with normal human tissues and
cynomolgus monkey tissues, and only cross-reacted with the positive-control. i.e.
human angiosarcoma tissue, suggesting that IBI305 is highly specific to cancer tissues
rather than normal human tissues and has very low on-target toxicity.
2)
Linearity: With single dose or repeated doses of IBI305 (2-50 mg/kg) vis intravenous
injection in cynomolgus monkeys, the test showed significant PK, thus reducing the
suddenly rising toxicity risks with increased clinical doses.
3)
Immunogenicity: With single dose or repeated doses of IBI305 or bevacizumab via
intravenous injection in cynomolgus monkeys, the test showed abnormal changes of
drug concentration-time curves in several animals. The anti-drug antibody (ADA) test
results showed that IBI305 has a medium immunogenicity.
4)
Accumulation: With repeated doses of IBI305 or bevacizumab via intravenous
injection in cynomolgus monkeys, the test showed that drug exposure of the last
dose was significantly higher than that of the first dose, and the steady-state drug
concentration after repeated doses was higher than that after a single dose, suggesting
that the drug may be accumulated in body.
The results of tissue cross-reactivity and PK/toxicokinetic studies in cynomolgus monkeys
indicated that IBI305 and bevacizumab have similar characteristics in tissue cross-reactivity and
PK/toxicokinetics13.
Toxicological studies
Toxicological studies of IBI305 showed the following findings:
1)
Single dose: With single dose of IBI305 (up to 300 mg/kg) via intravenous injection in
cynomolgus monkeys, the test showed good tolerability without any abnormal clinical
symptoms and toxicity. The dose was about 48 times the proposed clinical dose for
human based on body surface area. In the safety pharmacology test, with single dose of
IBI305 (50 mg/kg) via intravenous injection in cynomolgus monkeys, the test showed
no significant effects on the central nervous system, respiratory system, and
cardiovascular system, suggesting that the single dose of IBI305 via intravenous
injection has a high safety.

2)
Repeated doses: With repeated doses of IBI305 (up to 50 mg/kg) via intravenous
injection twice weekly for 9 consecutive doses in cynomolgus monkeys, equivalent to
20 times the proposed clinical dose for humans (based on the weight), the test showed
extremely mild to mild linear growth arrest of metaphyseal lines at knee joint and
disordered chondrocyte proliferation, extremely mild increases in macrophage count
in white pulp of spleen, pulmonary (including bronchial) hemorrhage, and deposits of
hemosiderin in lymphoid tissue of bronchial mucosa, indicating that the target organ
toxicities are mainly in the bone, spleen, and lungs.
3)
Immunotoxicity and immunogenicity: With repeated doses of IBI305 via intravenous
injection twice weekly for 9 consecutive in cynomolgus monkeys, the test showed
medium immunotoxicity to the spleen. Different doses of IBI305 may result in the
production of ADAs, a portion of which are neutralizing antibodies (NAbs), indicating
that IBI305 has medium immunotoxicity and immunogenicity.
4)
Local irritation test: With repeated dose of IBI305 via intravenous injection in
cynomolgus monkeys, the test showed no irritation at the injection site, suggesting that
administration of IBI305 via intravenous injection is safe and feasible.
5)
In vitro hemolysis assay: With maximum proposed clinical concentration of IBI305
(9 mg/mL), the assay showed no hemolysis, suggesting that IBI305 is suitable for
intravenous injection.
IBI305 has high similarity with bevacizumab in safety pharmacology, long-term toxicity,
immunotoxicity, immunogenicity, local irritation, and hemolysis13.
1.1.2.3 Clinical studies
This study is the first study of IBI305 in humans.
1.2 Study Principles and Risk/Benefit Assessment
1.2.1 Study principles and dose selection
A biosimilar drug refers to a therapeutic biological product that is similar in quality, safety and
efficacy with an approved reference drug14. IBI305, developed and sold in the market by the
sponsor, is a bevacizumab biosimilar, and has the same administration method and indications
as bevacizumab.

This study is conducted in accordance with the "Guidelines on Development and Evaluation of
Bosimilars (for Trial Version)" issued by the NMPA (formerly CFDA)14. The doses of IBI305
selected in this study are based on the preclinical studies that showed highly similarity between
IBI305 and bevacizumab in pharmacology, PD, PK and toxicology (refer to the Investigator's
Brochure for details). Besides, the efficacy and safety of bevacizumab for treatment of advanced,
metastatic or relapsed non-squamous NSCLC have been verified, and the indications have also
been approved in China. Therefore, the dose and administration of IBI305 is similar to
bevacizumab in this study, that is, 15 mg/kg intravenously on D1 of every 3-week cycle
when used in combination with chemotherapy (paclitaxel and carboplatin). In the subsequent
monotherapy therapy, IBI305 will be given intravenously at a dose of 7.5 mg/kg on the first day
of every 3-week cycle. This design of this study is to further demonstrate that IBI305 is similar
to bevacizumab in clinical efficacy, safety, and immunogenicity in subjects with advanced,
metastatic or relapsed non-squamous NSCLC.
1.2.2 Risk/benefit assessment
IBI305 is a bevacizumab biosimilar developed by the sponsor. Based on the clinical pharmacology
and toxicology characteristics of IBI305, the risks and benefits of IBI305 are expected to be similar
to bevacizumab.
The treatment-related risks of bevacizumab are detailed in its prescribing information. This study
is the first human study of IBI305 so that unexpected adverse reactions will be possible. The
design of this study ensures the minimized subject risks by close monitoring of the adverse
events (AEs) before, during, and after the infusion of the investigational drugs. Once an adverse
reaction occurs, the investigator will immediately take appropriate action for the subject safety.
The platinum-based therapy is the standard first-line regimen of advanced NSCLC4. This study
uses the combination of paclitaxel/carboplatin, ensuring the basic anti-tumor therapy for subjects.

3 STUDY PLAN
3.1 Overview of Study Design
This is a randomized, double-blind, active-controlled, and multi-center phase III study. A total of
400 subjects across 35 study sites with non-squamous NSCLC will be planned, randomized in a
1:1 ratio into the IBI305 plus paclitaxel/carboplatin group or bevacizumab plus paclitaxel/carboplatin
group, and stratified according to age (< 60 vs. ≥60 years old) and epidermal growth factor
receptor (EGFR) status (wild type vs. mutant). Each treatment cycle is 3 weeks for both groups.
15 mg/kg IBI305 or bevacizumab is administered on D1 of each cycle along with paclitaxel/carboplatin.
Subjects will receive up to 6 treatment cycles of combination therapy until PD, unacceptable
toxicity, withdrawal of informed consent, loss of follow-up, or death (whichever comes first).
Then subjects received monotherapy, that is, discontinuing paclitaxel/carboplatin while
continuing therapy with IBI305 or bevacizumab. The monotherapy continues every 3 weeks.
On D1 of each treatment cycle, subjects will be administered 7.5 mg/kg of either IBI305 or
bevacizumab until PD, unacceptable toxicity, withdrawal of informed consent, lost to follow-up,
death, or end of study (whichever comes first).
After discontinuing the study drug, subjects will return to the study site 28 days (± 7 days) after
the last dose for an end-of-treatment visit. If the subjects discontinue the study treatment for
reasons other than PD, subsequent follow-up will be continued until PD, withdrawal of informed
consent, start of other anti-tumor therapies, loss of follow-up, death, or end of study. If the
subjects discontinue the study treatment for PD, the investigator will make telephone follow-up
every 12 weeks (± 7 days) to collect information of subsequent anti-tumor therapies and survival.
A CT or an MRI will be performed every 6 weeks (± 7 days) until PD, withdrawal of informed
consent, start of other anti-tumor therapies, loss of follow-up, death, or end of study. The method
for subsequent imaging examination should be consistent with that at baseline, and the chest,
abdomen and pelvis of the subject must be scanned. Each assessment must be completed within
7 days from the most recent visit. The investigators then perform the evaluation based on the
RECIST 1.1 criteria to determine whether the subject can continue receiving the next cycle of
treatment. Furthermore, the independent tumor evaluation committee (Section 11.1.1) will also
evaluate tumor response according to the RECIST version 1.1. If the subject discontinue the
study treatment for reasons other than PD, subsequent tumor evaluation should be continued
according to the study procedures until PD, withdrawal of informed consent, start of other anti-
tumor therapies, loss of follow-up, death or, end of study.
The study design is shown in Figure 1.

5 STUDY TREATMENT
5.1 Therapies by Study Drugs
The study drugs of this study are IBI305 and bevacizumab.
In this study, the dose of IBI305 or bevacizumab during combination therapy with chemotherapy
is 15 mg/kg, while the dose during monotherapy is 7.5 mg/kg. The study drugs are administered
intravenously on D1 of each 3-week cycle until PD, unacceptable toxicity, withdrawal of informed
consent, loss to follow-up, death, or end of study (whichever comes first).
The duration of the first dose of IBI305 or bevacizumab should be 90 min (± 15 min). If the
first infusion is well-tolerated by the subject, then the duration of the second infusion can be
shortened to 60 min (± 15 min). If the 60 min infusion is also well-tolerated by the subject, then
the subsequent infusions can be completed within 30 min (± 15 min).
5.2 Chemotherapy
Paclitaxel will be administered after the IBI305 or bevacizumab infusion is completed, then
followed by carboplatin:
Paclitaxel: 175 mg/m² administered via intravenous infusion for 3 h (may be adjusted according
to clinical practice of each study site) on D1 of every 3-week cycle for up to 6 cycles until PD,
unacceptable toxicity, withdrawal of informed consent, loss of follow-up, or death.
Carboplatin: AUC 6.0 administered via intravenous infusion for 15-30 min (may be adjusted
according to clinical practice of each study site) on D1 of every 3-week cycle for up to 6 cycles
until PD, unacceptable toxicity, withdrawal of informed consent, loss of follow-up, or death.
The chemotherapeutic agents are supplied by the sponsor.
Formulas for calculating surface area, creatinine clearance and carboplatin dose are shown in
Section 13.2.
5.3 Dose Adjustment of Each Study Drug
5.3.1 General principles
The reasons for dose adjustments or delayed administration, measures taken, and
results should be documented in the medical records and eCRFs

Confidential
If the concomitant symptoms exist at baseline, the investigator will determine whether
the dose should be adjusted according to the change in severity of toxicity. For example,
if the subject has Grade 1 "weakness" at baseline and Grade 2 "weakness" during the
study treatment, the dose should be adjusted based on Grade 1 toxicity since the
severity has increased by one grade
If several toxic reactions of different grades or severity occur simultaneously, the dose
will be adjusted according to the highest observed grade/severity
If a dose adjustment is required solely due to abnormal lab test results, then the dose
should be adjusted based on the measured values obtained prior to the start of the
treatment cycle
If the investigator determines that the toxicity is unlikely to further develop into a
serious or life-threatening event, the current dose will be continued without any
adjustments or treatment interruptions. In addition, dose adjustments or treatment
interruptions will not be performed for non-hemolytic anemia as the symptoms can be
alleviated through blood transfusions.
If the investigator determines that a toxicity is caused by a specific therapeutic drug,
then the dose adjustments of other drugs are not required
Discontinuation of one or two therapeutic drugs before PD will not affect the continued
treatment with other drugs
Dose reductions or adjustments of IBI305 or bevacizumab are not permitted.
Subsequent therapeutic dose will not be adjusted according to weight change, unless
the subject weight has changed by ≥10% from baseline
Once the dose of any chemotherapeutic agents is reduced, the original dose should no
longer be adopted
If any but not all of the therapeutic drug (IBI305, bevacizumab or chemotherapeutic
agents) treatments is interrupted due to toxicity, then this treatment will be considered
as a treatment cycle
If the administration of any one of the chemotherapeutic agents is delayed for more
than 3 weeks, the subject should permanently discontinue that chemotherapeutic agent

5.3.2 Dose adjustments of study drugs
Dose adjustments of IBI305 or bevacizumab are not permitted except for the adjustments
(adjusted to 7.5 mg/kg for monotherapy) specified in the study protocol. The dose of IBI305 or
bevacizumab is calculated according to the subject weight at baseline (prior to the first dose), and
remains unchanged throughout the study, unless the subject weight has changed by ≥10% from
baseline.
If an infusion reaction occurs during a 60-minute infusion, the infusion time should be extended
to 90 minutes for all subsequent infusions. Likewise, if an infusion reaction occurs during a 30-
minute infusion, the infusion time should be extended to 60 minutes for all subsequent infusions.
IBI305 or bevacizumab in combination with paclitaxel/carboplatin will be administered every
3-week treatment cycle for 6 cycles. If PD is not observed in subject during treatment, then the
subject will continue to receive IBI305 or bevacizumab as monotherapy every 3-week treatment
cycle until PD, unacceptable toxicity, withdrawal of informed consent, loss of follow-up, death,
or end of study (whichever comes first).
If IBI305 or bevacizumab is permanently discontinued due to unacceptable toxicity or subject
refusal to continue the study drugs during the combination therapy, then the subject will continue
to receive the chemotherapy (paclitaxel/carboplatin) until 6 treatment cycles are completed as
determined by the investigator. If any one of the chemotherapeutic agents (paclitaxel or carboplatin)
is prematurely discontinued due to unacceptable toxicity, the subject can continue to receive
IBI305 or bevacizumab treatment until PD, unacceptable toxicity, withdrawal of informed
consent, loss of follow-up, or death (whichever comes first).
When a Grade 3 or 4 IBI305- or bevacizumab-related toxicity is observed, the investigators
should determine whether to continue or terminate IBI305 or bevacizumab treatment according
to the followings:
First occurrence:
IBI305 or bevacizumab administration should be interrupted until toxicity symptoms return to
baseline level or are at least reduced to the Common Terminology Criteria for Adverse Events
(CTCAE) Grade 1 or lower (except for the special circumstances listed below)
Note that when Grade 4 febrile neutropenia and/or thrombocytopenia occur(s), IBI305
or bevacizumab administration should be interrupted until the symptoms return to
baseline levels or at least reduced to CTCAE Grade 1 or lower, since these events
increase the risk of hemorrhage.

Re-occurrence in re-administration:
If Grade 3 IBI305- or bevacizumab-related toxicity occurs again, the investigator
should assess the risk/benefit of study drug continuation for the subject. If such toxicity
re-occurs again after re-administration, IBI305 or bevacizumab should be permanently
discontinued
If Grade 4 IBI305- or bevacizumab-related toxicity occurs again, IBI305 or
bevacizumab should be permanently discontinued
Measures should be taken in the following special circumstances (classified based on CTCAE
version 4.03):
Hemorrhage
Subjects with Grade 3 or 4 hemorrhages should be treated accordingly and permanently
discontinue the study treatment
Thrombosis/embolism

Subjects with arterial thrombosis of any severity grades should permanently
discontinue the study treatment

Subjects with Grade 4 venous thrombosis should permanently discontinue the
study treatment

Subjects with Grade 3 venous thrombosis should interrupt the study treatment. If
the anticoagulant therapy at the planned therapeutic dose is < 2 weeks, the study
treatment should be interrupted until the anticoagulant therapy is completed. If
the anticoagulant therapy at the planned therapeutic dose is > 2 weeks, IBI305
or bevacizumab administration should be interrupted for 2 weeks, and the study
treatment can be restarted during the anticoagulant therapy if the following criteria
are met:
- INR is within the target range (usually 2-3) prior to restarting of study treatment
- Subjects must not have experienced Grade 3 or 4 hemorrhage since enrollment
- No signs of great vessel invasion or adjacency to great vessels from previous
tumor assessments
Note: Therapeutic dose of anticoagulant therapy is defined as the escalating dose of
warfarin or other anticogulants until INR is maintained at no less than 1.5 (usually

2-3). The warfarin dose should be documented in the eCRFs, and the INR of
subjects receiving anticoagulant therapy should be monitored during the treatment.
Hypertension
BP should be measured frequently to monitor the occurrence and exacerbation of hypertension.
Subjects should remain at resting position for at least 5 min before BP measurement.
Grade 1 hypertension: Asymptomatic transient (< 24 h) increase in BP (> 20 mmHg
diastolic blood pressure), or > 150/100 mmHg in this measurement, but previous BP
was within normal range. No interventions are required.
Grade 2 hypertension: Repeated or sustained (> 24 h) or symptomatic BP increase (>
20 mmHg diastolic blood pressure), or > 150/100 mmHg in this measurement, but
previous BP was within normal range. One antihypertensive drug can be used. Once
BP is lowered to < 150/100 mmHg, the subject may continue the study treatment.
Grade 3 hypertension: Requires more than one antihypertensive drugs or more potent
treatment. Study treatment should be interrupted in case of persistent or symptomatic
hypertension; study treatment should be permanently discontinued for uncontrollable
hypertension.
Grade 4 hypertension: Life-threatening (i.e. hypertensive crisis). The study treatment
should be permanently discontinued in case of Grade 4 hypertension. The dose of all
antihypertensive agents used should be documented during each visit.
The dose of antihypertensive agents used should be documented during each visit. If the subject
remains hypertensive despite treatment discontinuation, BP and antihypertensive agents used
should be monitored every 3 months until BP returns to normal or end of study.
Reversible posterior leukoencephalopathy syndrome (RPLS)
There have been a few reports with signs and symptoms consist with RPLS after study treatment.
RPLS is a rare neurological disease and its signs and symptoms include epilepsy, headache,
altered mental status, visual impairment, or cortical blindness, with or without hypertension.
Subjects with RPLS should permanently discontinue the study treatment.
Proteinuria
Urinalysis dipstick test should be performed prior to each IBI305 or bevacizumab infusion unless
24-h proteinuria test has already been performed.

First occurrence of proteinuria:
The urinalysis dipstick test should be performed if:
Urine protein is < 2+, continue study treatment as scheduled, no additional tests are
required.
Urine protein is ≥2+ (strip test), continue study treatment as scheduled, and a 24-h
urine protein test should be performed within 3 days prior to the next treatment cycle:

If 24-h urine protein is < 2 g, continue study treatment as scheduled, and perform
urinalysis dipstick test before each scheduled dose.

If 24-h urine protein is > 2 g, the current study treatment is interrupted, and a 24-h
urine protein test should be performed within 3 days prior to the next planned dose.
Study treatment is delayed until 24-h urine protein is ≤2 g, and a 24-h urine protein
test prior to each subsequent dose is performed until urine protein is reduced to ≤
1 g/24 h. Interrupt study treatment only when 24-h urine protein is > 2 g.
Second and subsequent occurrence of proteinuria:
< 3+ (strip test): continue study treatment as scheduled, no additional tests are required.
Urine protein is ≥3+ (strip test), continue study treatment as scheduled, and a 24-h
urine protein test should be performed within 3 days prior to the next treatment cycle:

If 24-h urine protein ≤2 g, continue study treatment as scheduled.

If 24-h urine protein is > 2 g, the current study treatment is interrupted, and a 24-h urine
protein test should be performed within 3 days prior to the next planned dose. Study
treatment is delayed until 24-h urine protein is ≤2 g, and a 24-h urine protein test
prior to each subsequent dose is performed until urine protein is reduced to ≤
1 g/24 h. Interrupt study treatment only when 24-h urine protein is > 2 g.
Nephrotic syndrome (Grade 4): Study treatment is permanently discontinued
Gastrointestinal perforation
If gastrointestinal perforation occurs, appropriate measures should be taken and the study
treatment should be permanently discontinued.
Wound healing complications
The study treatment should not begin within 28 d after a major surgery, or before the surgical

wound is fully healed. If a complication of wound healing occurs during study treatment, the
study treatment should be interrupted until the wound is fully healed. If an elective surgery is
required, the study treatment should be interrupted.
Abdominal abscess or fistula
If abdominal abscess or fistula occurs, the study treatment should be discontinued. However, the
investigator will determine whether study treatment will be continued if the above AE is resolved.

Infusion-related and allergic reactions:
Infusion-related reactions after first dose of the study drug is uncommon (< 3%), and the incidence
of a severe reaction is only 0.2%.
If a mild (grade 1 or 2) reaction (such as fever, chills, headache, and nausea) occurs, pretreatment
prior to subsequent administration should be performed and infusion time should not be reduced.
If the subject is well-tolerated during infusion after pretreatment, the infusion time can be
reduced by 30 minutes (+10 minutes) for subsequent administration with pretreatment. If an
infusion-related AE occurs during a 60-minute infusion, the subsequent infusion should be
completed within 90 minutes (+15 minutes) with pretreatment. Likewise, if an infusion-related
AE occurs during a 30-minute infusion, the subsequent infusion should be completed in 60 minutes
(+10 minutes) with pretreatment. If a subject has a grade 3 infusion-related reaction, the study
treatment should be interrupted and not be restarted on the same day. However, since there lacks
the dose adjustment method for grade 3 infusion-related reactions, the investigators may decide
to either discontinue the study drug or perform pretreatment, and complete the infusion within
90 minutes (+15 minutes). If an adverse reaction still occurs during a 90-minute infusion, the
infusion should be continued at a slower rate and then gradually returned to a 90-minute infusion.
If the investigator is uncertain about the handling, the study treatment should be discontinued.
When the study treatment is restarted, the subject should be closely monitored based on routine
clinical practice until the possible time of adverse reaction has passed. If a subject has a grade 4
infusion-related reaction, the study treatment should be discontinued.
An allergic reaction is defined as the vascular collapse or shock (systolic BP < 90 mmHg,
unresponsive to rehydration) that occurs within 30 minutes of a study drug infusion caused by
an allergy, with or without respiratory distress. Skin reactions include pruritus, urticaria, and
angioedema. Subjects with allergic reactions should discontinue the study treatment.
5.3.3 Dose adjustments of chemotherapy
Paclitaxel and carboplatin should be administered according to the study site guidelines and local
prescribing information. For the specific information for use, preparation, and storage of
paclitaxel and carboplatin, refer to the prescribing information and local dosing information.
Carboplatin-based chemotherapies have a relatively high incidence of emesis. Therefore,
antiemetics for prophylaxis can be used.
Hematological toxicity:
Absolute neutrophil count (ANC; dose can only be reduced when febrile neutropenia occurs.
ANC must be ≥1.5 × 109/L and platelet count ≥100 × 109/L on D1 of each treatment cycle)

Once the chemotherapeutic dose is reduced due to febrile neutropenia or thrombocytopenia
(platelet count < 25 × 109/L or < 50 × 109/L with hemorrhage or blood transfusion required), the
original dose should no longer be adopted. If dose reduction is required due to another incident
of febrile neutropenia or thrombocytopenia, the dose of paclitaxel and carboplatin will be
reduced to 100 mg/m2 and AUC 3.0, respectively. If the dose reduction is required for the third
time, the chemotherapy should be immediately discontinued.
If the dose adjustment is required when ANC and thrombocytopenia occur concurrently, the low-
dose chemotherapy should be adopted.
Chemotherapy may be delayed for up to 3 weeks. If after the chemotherapy has been delayed for
3 weeks, ANC does not reach ≥1.5 × 109/L and platelet count does not reach ≥100 × 109/L on
D1 of the scheduled chemotherapy, the chemotherapy should be permanently discontinued. If the
above values have been reached, the next course of chemotherapy should be continued.
The investigator should monitor the subject closely for toxicity with particular attention to early
and evident signs of myelosuppression, infection, or febrile neutropenia to timely and
appropriately treat the complications.
Subjects should be informed to pay attention to these signs and receive treatment as soon as possible.

If the chemotherapy must be interrupted due to hematological toxicity, the complete blood count
should be performed regularly (including WBC differentials) until all the counts reach the
minimum requirements for treatment continuation. Thereafter the scheduled treatment plan will
be performed.
Dose adjustments are not required for anemia. However, treatment based on guidelines of each
clinic should be performed.

Antiemetics will be used to control nausea and/or emesis. If grade 3 or 4 nausea and/or emesis
occur(s) despite of antiemetics, the chemotherapeutic dose should be reduced by 20% for the
next treatment cycle. The dose should be returned to the initial level as possible if the subject is
tolerated.
If the subject experiences stomatitis on D1 of any treatment cycle, the chemotherapy should be
interrupted until the symptoms resolve. If the stomatitis has not resolved after 3 weeks, the
chemotherapy should be permanently discontinued (refer to CTCAE version 4.03). If an acute
Grade 3 stomatitis occurs, the chemotherapeutic dose should be reduced to 75% of the proposed
dose when symptoms resolve.
Hepatotoxicity (Paclitaxel)
The paclitaxel dose should be determined based on the lab values measured on D1 of each
treatment cycle.

If paclitaxel is interrupted due to hepatotoxicity, carboplatin should also be interrupted until
paclitaxel is restarted. Paclitaxel will be interrupted for up to 3 weeks. If the subject's hepatic
function does not return to the acceptable ranges in 3 weeks, paclitaxel should be permanently
discontinued. The carboplatin dose will not be adjusted when hepatotoxicity occurs.

The investigators should avoid PD due to abnormal hepatic enzyme levels as possible. If PD
occurs, all the study drugs should be permanently discontinued, including chemotherapy.
Cardiovascular toxicity (paclitaxel)
The arrhythmia in subjects was infrequent in previous clinical studies. However, most subjects
were asymptomatic and electrocardiographic monitoring was not required. Asymptomatic
transient bradycardia was observed in 29% of subjects, but significant atrioventricular block was
rare. Cardiac events should be treated as follows:
Asymptomatic bradycardia: no intervention indicated
Symptomatic arrhythmia during infusion: Discontinue paclitaxel infusion and perform
routine treatment of arrhythmia. Discontinue subsequent paclitaxel treatment.
Document this AE in the AE Report Form of eCRF.
Chest pain and/or symptomatic hypotension (< 90/60 mmHg or rehydration therapy
required): discontinue the paclitaxel infusion. Perform electrocardiography (ECG). If
hypersensitivity reaction is suspected, administer diphenhydramine and dexamethasone
via intravenous infusion. If the chest pain is not considered as cardiogenic, epinephrine
or bronchodilators will be administered. Document this AE in the AE Report Form of
eCRF. Discontinue subsequent paclitaxel treatment and provide symptomatic treatment.
Consult a cardiologist if needed.
Neurotoxicity (paclitaxel)
The dose of paclitaxel should be adjusted according to Table when neuropathy occurs. The dose
adjustment of carboplatin is not needed when neurotoxicity occurs.

If the neurotoxicity does not return to grade 1 after paclitaxel interruption for 3 weeks, paclitaxel
should be permanently discontinued.
Allergic reactions/hypersensitivity reactions (paclitaxel)
Note: Prophylaxis for hypersensitivity reactions (see below) and close monitoring of vital signs
are recommended for subjects with history of mild to moderate hypersensitivity reactions when
hypersensitivity reactions reoccur.
Mild symptoms: complete paclitaxel infusion. Close monitoring; no treatment indicated.
Moderate symptoms: Interrupt paclitaxel infusion, administer diphenhydramine 25–
50 mg and dexamethasone 10 mg via intravenous infusion. Once symptoms have
resolved, resume paclitaxel infusion at a slower rate (20 mL/hour for 15 minutes, then
at 40 mL/hour for 15 minutes, and if no further symptoms develop, continue at original
rate until infusion is complete). Document this AE in the AE Report Form of eCRF. If
symptoms reoccur, interrupt the paclitaxel infusion and permanently discontinue
subsequent paclitaxel infusion.
Severe and life-threatening symptoms: Interrupt paclitaxel infusion, administer
diphenhydramine and dexamethasone via intravenous infusion (as above). Use
epinephrine or bronchodilators if indicated. Document this AE in the AE Report Form
of eCRF. Subsequent courses of paclitaxel infusion should be permanently
discontinued.
Moderate or severe hypersensitivity reactions should be documented as AEs.
Other toxicities
If other unmentioned grade 3–4 toxicities occur, the chemotherapy should be interrupted until
symptoms resolve or return to grade 1. Thereafter restart the infusion at 50% of the original dose
(which should no longer be adopted). If the toxicity does not return to grade 1 after an
interruption for 3 weeks, the chemotherapy should be permanently discontinued. Dose
adjustments are not recommended for grade 1 and 2 toxicities.
Investigator should closely monitor toxicities in subjects during chemotherapy. Before the start
of next chemotherapy cycle, the laboratory test results must be:

ANC ≥1.5 × 109/L

Platelet count ≥100 × 109/L

5.7 Subjects Allocation
After confirming that the subject meets all of the inclusion and exclusion criteria, the study site
will log in the Interactive Web Response System (IWRS) and enter the subject information into
the IWRS. The IWRS will allocate a random number to the subject and provide a medication
number. Stratified randomization is used in this study. Stratifying factors include age (< 60 vs.
≥60 years old) and EGFR status (wild vs. mutant type).
5.8 Blinding
This is a randomized, double-blind, and active-controlled study, and only relevant study
personnel had access to the randomization numbers. A non-blinded pharmacist or research nurse
will prepare the medications since IBI305 and bevacizumab do not have an identical appearance.
The pharmacist or research nurse who is responsible for preparing the study drugs is not allowed
to disclose any information regarding treatment allocation to the subject, the subject's family
members, or other personnel including the physician and the relevant study staff.
Unblinding: Subject unblinding should only be performed after database locking.
Emergency unblinding: In case of an emergency where the investigator must know the
medication given to a particular subject, the investigator will unblind the subject via the IWRS
and immediately inform the sponsor and CRO. The reasons for unblinding, date, and outcomes
should be documented in the source document and eCRF of the subject.
5.9 Concomitant Medications and Treatments
All medications except for the study drugs, including other chemotherapies not specified in the
study, Chinese herbal medicines, and other non-traditional therapies, are considered concomitant
medications. All concomitant medications used within 30 days prior to screening should be
documented in the eCRFs, including the information of generic name, route of administration,
start date, end date, and indication.
5.9.1 Prohibited medications
No other anti-tumor therapies or medications with anti-tumor indications, including Chinese
herbal medicine, radiotherapy, or other investigational drugs, are allowed during this study other
than IBI305, bevacizumab, paclitaxel, and carboplatin.
Severe myelosuppression is possible after chemotherapy. Granulocyte colony-stimulating factor
or granulocyte-macrophage colony-stimulating factor are not allowed to be used prophylactically
in the first treatment cycle.

5.9.2 Medications allowed
Prophylactic use of anti-emetics, glucocorticoids, or other treatments targeting toxicities is permitted
during the study. Unconventional treatments (such as acupuncture) and vitamins/microelements are
permitted if their use does not affect the study endpoints as determined by the investigators.
Starting from the 2nd chemotherapy cycle, granulocyte colony-stimulating factor or granulocyte-
macrophage colony-stimulating factor are allowed to be used prophylactically to prevent severe
myelosuppression.
5.9.3 Treatment after study treatment
Subsequent therapy after the end of study treatment should be determined by the subject's
attending doctor.
5.10 Treatment Compliance
The dosage and dosing time of IBI305 or bevacizumab and paclitaxel + carboplatin in each
treatment cycle should be documented in the eCRFs. Reasons for dosing delay, dose reduction or
missed dossing should also be documented in the eCRFs.
Treatment and protocol compliance refers to the subject's voluntary compliance with each aspect
of the protocol, including compliance with blood collection for safety evaluation and imaging
examination for tumor assessment. If a subject does not return for the scheduled follow-up visits,
his/her participation in the study may be terminated based on the opinions of the primary
investigator or sponsor.
5.11 Study Drug Count
The investigator, other relevant stuff, or authorized pharmacists should document the receipt and
distribution of study drugs on the study drug count table and ensure that the table is readily
available for inspection.
The study drugs are only for the use of study subjects. At the end of the trial, all study drugs
should be counted and explanations for deviations should be provided in a written document.
The investigator shall count all unused study drugs and packaging materials, and return them to
the sponsor or the designated third party. Used empty drug bottles/bags will be destroyed on-site
according to the institutional standards.

6.10 Disease Progression Visit
If the study drugs are discontinued for reasons other than PD, the end of treatment visit in study
sites will be conducted in 28 days after the last dose of study drug, and tumor assessments should
be conducted every 6 weeks (±7 days) until PD if possible (after which, follow-up for survival
will be conducted [Section 6.11]), withdraw of informed consent, loss to follow-up, death,
start of other anti-tumor therapies, or end of study. During the visit, vital signs and weight
measurements will be performed, and any subsequent anti-tumor therapies will be documented.
6.11 Survival Follow-Up
The investigator will make telephone follow-up every 12 weeks (±7 days) to collect the
information of subsequent anti-tumor therapies and survival until withdrawal of informed
consent, loss to follow-up, death, or end of study.
6.12 Study Completion
Completion of this clinical study is defined as 18 months after the enrollment of the last subject.
If the subjects continue to receive the study drug treatment before this cut-off time, the treatment
should be discontinued and the end of treatment visit should be completed (Section 6.9).
6.13 Tumor Assessment
Imaging tests (CT or MRI) of the brain, chest, abdomen, and pelvis are required at baseline. If
these tests are performed within 28 days prior to the first dose of the study drug, they do not need
to be repeated unless the investigator believes that there have been changes in the subject's tumor
burden. After the start of treatment, imaging tests are performed once every 6 weeks (±7 days)
and have to be completed within 7 days prior to the scheduled visits, until progressive disease,
start of other treatment, withdrawal of informed consent, loss to follow-up, death, or study
completion. The same method of imaging test was used at baseline and during follow-up.
Imaging evaluations of the chest, abdomen, and pelvis are required.
The investigator should perform a tumor assessment based on RECIST v1.1 (Section 13.3) prior
to each dose to determine whether the subject should continue with the next round of treatment.
An independent review committee will also assess the tumor response (Section 11.1.1). Imaging
tests will not be rescheduled if the study drugs or chemotherapeutic agents are interrupted due to
toxicities. Every effort should be made to continue the schedule for imaging tests even for
subjects who discontinue one or two study treatment(s) due to drug-related toxicities.
If subject experience PD according to the RECIST v 1.1 criteria, the attending doctor should
discuss with the subject regarding subsequent routine cancer therapies.

Pregnancy test: Serum pregnancy tests are performed on women of childbearing age
during screening and the end-of-treatment visit.
These tests are carried out at the laboratory of each trial site.
For subsequent visits, all laboratory tests need to be completed within 3 days prior to the
administration. During the study, the frequency of these laboratory tests will be increased if
safety is a concern. The investigator should review the laboratory test results throughout the
study to determine whether the results are clinically significant. The investigator should assess
the changes in laboratory test results. If the investigator considers a laboratory test result to be
abnormal and of clinical significance, it is considered as an AE.

6.15.4 12-Lead ECG
The subject will undergo a 12-lead ECG during screening, and also during the course of the
study if deemed necessary by the investigator.
The following ECG parameters should be documented: HR, PR-interval, QRS-complex, QT-
interval, and QTc-interval. The subject must be in the supine position for at least 5 minutes prior
to undergoing the 12-lead ECG. All ECG are evaluated by qualified physicians. All clinically
significant abnormal findings should be reported as AEs.
6.15.5 Immunogenicity assessment
Blood samples are collected before the first dose, on D1 of Cycle 4, and during the end-of-treatment
visit for immunogenicity assessment including testing of anti-drug antibodies and neutralizing
antibodies. Immunogenicity testing will be carried out at the relevant central laboratory. Details
regarding sample collection, processing, labeling, storage, transport, and analysis are provided in
the Central Laboratory Manual.
6.15.6 EGFR testing
All subjects should undergo tumor tissue EGFR testing during screening at the laboratory of each
trial site (The test does not need to be repeated if it can be confirmed with relevant reports that
the test has already been completed at the trial site).

a.
After completing the on-site end-of-treatment visit 28 days after the last dose, subjects who discontinue the investigational drug treatment due to reasons
other than PD should continue to undergo tumor assessments once every 6 weeks (±7 days) until PD (and begin post-PD follow-up thereafter), withdrawal
of consent, start of another antineoplastic treatment, loss to follow-up, death, or study completion.
b.
For subjects with PD, collect survival information once every 12 weeks (84 days, ±7 days) by phone until death, loss to follow-up, withdrawal of informed
consent, or study completion. Subsequent antineoplastic treatments should be documented in the eCRF.

d.
Clinical laboratory tests are carried out at the laboratory of each hospital. If screening laboratory tests (routine blood test, blood chemistry, and urinalysis)
are performed within 7 days prior to the first dose, the screening results may be used as baseline data. For subsequent visits, all laboratory tests have to be
completed within 3 days prior to the dose administration.
e.
Prior to each IBI305/bevacizumab infusion, test paper should be used to examine urinary protein.
f.
Women of childbearing age should undergo serum pregnancy tests.
g.
Immunogenicity testing (for anti-drug antibodies and neutralizing antibodies) is performed at the central laboratory.
h.
Image assessments (CT or MRI) of the brain, chest, abdomen, and pelvis should be completed at baseline. If these tests are performed within 28 days prior
to the first dose of the study drug, they do not need to be repeated unless the investigator believes that there have been changes in the subject's tumor burden.
After the start of treatment, imaging tests are performed once every 6 weeks (±7 days) and have to be completed within 7 days prior to the scheduled visits,
until progressive disease, start of other treatment, withdrawal of informed consent, loss to follow-up, death, or study completion. The same method of
imaging test is used at baseline and during follow-up. Imaging evaluations of the chest, abdomen, and pelvis are required.
i.
All subjects should undergo tumor tissue EGFR testing, but the test does not need to be repeated if it can be confirmed with relevant reports that the test has
already been completed at the trial site. EGFR testing will be carried out at the laboratory of each trial site.
j.
Each treatment cycle for the investigational drug is 3 weeks long. IBI305 or bevacizumab is administered on D1 of each cycle, at 15 mg/kg during
combination treatment with chemotherapy and 7.5 mg/kg during monotherapy, until disease progression (PD), unacceptable toxicity, withdrawal of
informed consent, loss to follow-up, death, or study completion, whichever occurs first. After all assessments are completed, the study drug is administered
followed by chemotherapy.
k.
Each treatment cycle is 3 weeks long. Chemotherapy (paclitaxel + carboplatin) is administered on D1 of each cycle for up to 6 cycles, or until disease
progression (PD), unacceptable toxicity, withdrawal of informed consent, loss to follow-up, or death. Paclitaxel is administered after the infusion of study
drug is completed, followed by carboplatin.

7 STUDY ASSESSMENTS
7.1 Efficacy Assessment
7.1.1 Primary efficacy endpoint

Objective response rate (ORR)
ORR will be assessed using RECIST v1.1. ORR is defined as the proportion of subjects whose
tumor volume has reduced to a predetermined value for a minimum time limit, including patients
who achieved complete response (CR) and partial response (PR). The cutoff date for the primary
efficacy endpoint analysis of this study is 6 months after subject randomization.
7.1.2 Secondary efficacy endpoints

Duration of response (DOR)

Progression-free survival (PFS)

Disease control rate (DCR)

Overall survival (OS)
Each endpoint will be assessed using RECIST v1.1.
DOR is defined as the time from initial tumor response (CR or PR) to PD or death before PD;
Subjects with CR or PR who do not progress or die will be censored on the date of the last tumor
assessment.
PFS is defined as the time from the date of randomization to the date of PD or death; Subjects
who do not progress or die will be censored on the date of the last tumor assessment.
DCR is defined as the proportion of patients whose tumor volume has reduced to a
predetermined value for a minimum time limit, including patients who achieved CR, PR, and SD.
OS is defined as the time from the date of randomization to the date of death of any cause. For
subjects that are alive on the date of study completion or are lost to follow-up, their survival time
will be censored at the date of last contact.

7.2 Safety Assessments
7.2.1 Adverse events
7.2.1.1 Definition
AEs
An adverse event is defined as any untoward medical occurrence suffered by the subject of the
clinical research, which does not necessarily have a causal relationship with the treatment.
An adverse event can therefore be any unfavorable and unintended sign (including an abnormal
laboratory finding), symptom, or disease temporally associated with the use of the investigational
drug, whether or not considered related to the investigational drug.
Serious adverse event
A serious adverse event does not necessarily have a causal relationship with the investigational
drug. It refers to any untoward medical occurrence that (at any dose of the investigational drug):
(1)
Results in death.
(2)
Is life-threatening (The term "life-threatening" refers to an event in which the subject is
at risk of death at the time of the event; it does not refer to an event which hypothetically
might have caused death if it is more severe).
(3)
Requires inpatient hospitalization or prolongation of existing hospitalization: This does
not include hospitalization and/or surgical procedures scheduled to be conducted prior
to or during the study for a disease or disorder that exists prior to study enrollment and
has not worsened during the course of the study.
(4)
Results in permanent or severe disability/incapacity.
(5)
Results in congenital anomalies/birth defects.
(6)
Other important medical events: Medical events that do not necessarily result in death,
are not life-threatening, and do not require hospitalization, but may jeopardize the
subject and may require medical or surgical intervention to prevent one of the aboves
outcomes, are also considered SAEs.
Note: Hospitalization as a result of PD is not considered an SAE.
Other Definitions
An adverse drug reaction (ADR) refers to any untoward response related to the investigational
drug after receiving any dose.

69 / 93
Confidential
An unexpected adverse drug reaction is any adverse reaction that is not consistent with
information known about the investigational drug.
7.2.1.2 Severity of adverse events
The severity of AEs will be assessed by CTCAE 4.03. The classifications are as follows:

Grade 1 Mild; asymptomatic or mild symptoms; clinical or diagnostic observations
only; intervention not indicated.

Grade 2 Moderate; minimal, local or noninvasive intervention indicated; limiting age-
appropriate instrumental ADL (e.g. preparing meals, shopping for groceries or clothes,
using the telephone, managing money, etc.)

Grade 3 Severe or medically significant but not immediately life-threatening;
hospitalization or prolongation of hospitalization indicated; disabling; limiting self care
ADL (e.g. bathing, dressing and undressing, feeding oneself, using the toilet, taking
medications, and not bedridden)

Grade 4
Life-threatening; urgent intervention indicated

Grade 5
Death related to AE
7.2.1.3 Relationship between adverse events and the investigational drug
The relationship between the investigational drug and AE can be classified into five categories:
definitely related, probably related, possibly related, unlikely related, and definitely unrelated.
Specific assessment criteria are as follows:

7.2.1.4 Serious adverse event reporting
Any SAE that occurs during the trial should be reported in accordance with SAE reporting
procedures of regulatory authorities or the ethics committee, regardless of whether the event is
related to treatment.
The investigator should take the following measures:

If necessary, take appropriate treatment measures immediately;

Immediately (within 24 hours after becoming aware of the event or obtaining new
information about the event) report the event to the sponsor's authorized representative
responsible for relevant safety information using a method approved by the sponsor;

Document the SAE in the AE and SAE section of the eCRF as well as in the source
documents;

The investigator must immediately (within 24 hours) submit the signed and dated SAE
Report to the independent ethics committee, NMPA (formerly CFDA), health
administration department, and local drug administration authorities;

Follow and document the course of the event, until the event resolves or returns to
baselines levels, or becomes clinically stable.
In addition, the sponsor or its representative (such as CRO) should report the SAE to the
corresponding regulatory agencies and other investigators in accordance with the requirements of
regulatory agencies and local regulations.
7.2.1.5 Management and follow-up of adverse events
The investigator is responsible for providing appropriate medical treatment for all AEs (Indicate
the actions taken, such as suspension/termination of the investigational drug, dose modification,
drug therapy, etc.). When an AE occurs, the investigator should actively take appropriate
measures to ensure the safety of the subject. All AEs observed from the signing of the ICF
to the time specified in the protocol (Table 2) must be followed. Refer to Section 7.2.1.8 for
the specific follow-up time.
The investigator should report any AE that occurs after the time specified in the protocol (Table 2)
and is suspected of being related to the investigational drug to the sponsor.

An AESI should also be reported as an SAE if the definition of SAE is met.
7.2.1.7 Pregnancy
Any pregnancy during the study, though not an SAE, must be reported using the Clinical Trial
Pregnancy Report. To ensure subject safety, the investigator must submit the report to the sponsor
or the sponsor's representative within 24 hours after becoming aware of the event. Pregnancies
must be followed to determine the outcome (including early termination) and the condition of the
mother and the baby. Complications and termination of pregnancy due to medical reasons should
be reported as AE or SAE. A spontaneous abortion should be reported as an SAE.
The investigator should pay attention to any pregnancy-related SAE that occurs after study
completion. Any SAE that the investigator believes may be related to the study treatment should
be reported immediately to the sponsor.
7.2.1.8 Summary of adverse event collection, documentation, and reporting
All adverse events that occur from the signing of the ICF to the time specified in the protocol
(Table 2) must be collected and documented in the AE page of the eCRF regardless of severity
(all SAEs and non-serious AEs).
The investigator must fill out all the required information, including the description of the AE,

8.3 General Principles for Statistical Analyses
For continuous variables, descriptive statistics should include the count, mean, standard
deviation, median, maximum, and minimum. For categorical variables, descriptive statistics will
include the frequency as well as the absolute or relative percentage. Statistical analyses will be
carried out using SAS 9.4.
8.4 Statistical Methods
8.4.1 Adjustments for covariates
Not applicable.
8.4.2 Managing dropouts and missing data
The analyses of primary and secondary endpoints will include data from dropouts. The management
of missing data is described in the Statistical Analysis Plan.
8.4.3 Interim analysis
There is no interim analysis planned for this study.
8.4.4 Multi-center study
Since this is a multicenter study, the primary endpoint (ORR) will be listed according to study
sites and treatment groups. However, individual equivalence analysis will not be conducted.
Trial sites with fewer than 5 ITT subjects per treatment group will need to be combined for
analysis. Details will be discussed in the data review meeting.
8.4.5 Multiple comparisons and adjustments to multiplicity
Not applicable.
8.5 Statistical Analyses
8.5.1 Subject distribution
Refer to Figure 1: Study design schematic for the schedule of activities. The number and
percentage of patients who have completed or dropped out of the study (including the reason for

The number and percentage of subjects in each analysis set are calculated based on treatment groups.
The number and percentage of protocol deviations are calculated based on treatment groups.
8.5.2 Demographics and other baseline characteristics
Demographic information such as age, height, sex, and weight, and other baseline characteristics
such as disease history (including NSCLC diagnosis, staging, previous cancer treatment, and
target and nontarget lesions) are summarized using descriptive statistics.
8.5.3 Compliance and drug exposure
The required dose and the actual dose must be documented in the eCRF. Subject compliance is
calculated based on the ratio of the actual dose (number of doses) to the required dose (number
of doses). Subject compliance is classified into the following categories: < 80%, 80–120%, and >
120%. The number and percentage of subjects in each category will be summarized.
8.5.4 Efficacy
The efficacy analysis will be based on the FAS. Results of the PP set will also be presented.
8.5.4.1 Primary efficacy endpoint
The primary objective of this study is to determine the clinical equivalence between IBI305 +
paclitaxel/carboplatin and bevacizumab + paclitaxel/carboplatin for the treatment of advanced or
relapsed non-squamous non-small cell lung cancer (NSCLC). The primary endpoint is objective
response rate (ORR). ORR is defined as the incidence of patients with confirmed complete
response (CR) or partial response (PR), when a validated imaging method and RECIST v1.1
are used to evaluate target and non-target lesions. Subjects without tumor assessments beyond
baseline will be considered unresponsive to treatment. Subjects qualified for the evaluation of
CR or PR must have at least one measurable lesion according to RECIST v1.1. The evaluation
of clinical equivalence will be based on the ORR provided by the independent review committee
(IRC). Results provided by the investigator will be used for sensitivity analysis.
Clinical equivalence will be declared if the 90% confidence interval of the difference in ORR
between IBI305 and bevacizumab groups falls within the preset margin of (-15%, 15%).
The ORR and corresponding 95% confidence interval of the two treatment groups, the ORR
difference and the 90% confidence interval, as well as the ORR ratio between the two groups and
the 90% confidence interval will be estimated using the generalized linear model (GLM, which
includes treatment groups and stratification factors).

8.5.4.2 Secondary efficacy endpoints
The secondary endpoints for this study include DOR, DCR, progress-free survival (PFS), and
overall survival (OS).
DCR is defined as the incidence of patients with confirmed complete response (CR), partial
response (PR), and stable disease (SD), when a validated imaging method and RECIST v1.1 are
used to evaluate target and non-target lesions.
DOR is defined as the time from initial tumor response (CR or PR) to PD or death; Subjects with
CR or PR who do not progress or die will be censored on the date of the last tumor assessment.
OS refers to the time from the date of randomization to the date of death (of any cause). For
subjects who are still alive at the time of the analysis, their survival time is censored on the last
known alive date. PFS refers to the time from the date of randomization to the date of first
documented PD or death, whichever occurs first. The investigator will assess PD using RECIST
v1.1. Subjects who do not progress or die will be censored on the date of the last tumor
assessment. Subjects without tumor assessments after baseline are censored on their date of
randomization.
Median OS and its 95% CI will be estimated using the Kaplan-Meier method. The survival curve
will be plotted. The hazard ratio (HR) between the two groups and its 95% CI will be estimated
using a Cox model. The Cox model includes treatment groups and stratification factors. DOR
and PFS will be analyzed using the same method as for OS. DCR will be analyzed using the
same method for primary efficacy endpoints, but an equivalence test will not be conducted.
8.5.4.3 Sensitivity analysis
The center effect (fixed or random) will be considered in the primary and secondary endpoints
analysis models (GLM or Cox).
8.5.4.4 Antibody and efficacy analysis
Subjects who develop antibodies during the clinical study will be summarized in detail. The
difference in efficacy between subjects with and without antibodies will be compared if
necessary.

9 QUALITY ASSURANCE AND QUALITY CONTROL
According to GCP principles, the sponsor is responsible for implementing and maintaining
quality assurance and quality control systems based on standard operating procedures (SOP),
to ensure that the implementation of the clinical trial and the collection, documentation, and
reporting of trial data is in accordance with the protocol, GCP, and applicable regulatory
requirements.
To ensure that the data is reliable and processed correctly, there should be quality control for
every step during the data processing.
In addition, the Clinical Quality Assurance (CQA) Department of the sponsor and/or CRO may
conduct regular audits of the study process, including but not limited to auditing the study site,
on-site visits, central laboratory, suppliers, clinical database, and the final clinical study report.
Regulatory authorities may also conduct inspections during the trial or at any time after the trial
is completed. The investigator and the research institution must allow the sponsor's representative
and regulatory authorities to review source data.
9.1 Clinical Monitoring
The sponsor has authorized Wuxi Clinical Co., Ltd. to conduct clinical monitoring for this study.
The clinical research associate (CRA) should follow the SOPs of Wuxi Clinical Co., Ltd. when
carrying out monitoring, and has the same rights and responsibilities as the sponsor's monitor.
The CRA should maintain regular communication with the investigator and the sponsor.
Before the start of the study, the associate monitor assess the qualifications of each study site,
and report issues related to facilities, technical equipment, or medical staff to the sponsor. During
the study, the CRA will be responsible for confirming whether written informed consent is
obtained from all subjects, and whether data documentation is accurate and complete. At the
same time, the CRA will compare data entered in to the eCRF with source data, and notify the
investigator of any errors or omissions. The CRA will also verify protocol compliance of the
study site, as well as the dispensing and storage of investigational drugs to ensure protocol
requirements are met.
The monitoring visit will be conducted in accordance with applicable statutes and regulations.
Each site receives regular monitoring visits from the time the subjects are enrolled. The CRA
should submit a written report to the sponsor after each monitoring visit to the study site.

9.2 Data Management/Coding
The Data Management and Biostatistics Department of Wuxi Clinical Co., Ltd will process data
generated from this study in accordance with relevant SOPs.
This study will use an electronic data capture (EDC) system. Trial data will be entered into the
eCRF by the investigator or authorized study personnel. Prior to launching of the study site or
data entry, the investigator and authorized study personnel will receive appropriate training, and
appropriate safety measures will be taken.
All data are input in Chinese. The eCRF should be completed during or soon after each visit, and
should be constantly updated to ensure that it reflects the latest status of the subject. To avoid
discrepancies in outcome assessments between different evaluators, ensure that baseline and all
subsequent efficacy and safety assessments for the same subject are performed by the same
person. The investigator must review trial data to ensure the accuracy and correctness of all data
entered into the eCRF. During the study, the investigator should document any evaluations that
are not conducted, or any information that is not available, applicable, or known. The
investigator need to sign all verified data electronically.
The CRA will review the eCRF, and evaluate its completeness and consistency. The CRA will
also compare the eCRF with the source documents to ensure the consistency of critical data. Data
entry, corrections, or modifications are completed by the investigator or designated staff. The
CRA do not have access to data entry. The data in eCRF is submitted to the data server, and any
changes to the data will be documented in the audit trail, including the reason for the change, the
name of the operator, as well as the time and date of the change. The roles and permissions of
study personnel responsible for data entry will be predetermined. The CRA or data manager will
submit data queries in the EDC system, and study personnel shall respond to the queries. The
EDC system will record the audit trail of each query, including the name of the investigator, as
well as the time and date.
Unless otherwise specified, the eCRF should be considered simply as a form for data collection
and not a source document. A source file is used by the investigator or hospital, relevant to the
subject, and can prove the existence of the subject, inclusion criteria, and all records of
participation in the study, including laboratory records, ECG results, memorandum, pharmacy
dispensing records, and subject folders.

Confidential
The investigators are required to maintain all source documents and to offer the documents to the
CRA for review during each visit. In addition, the investigator must submit a complete eCRF for
each subject, regardless of the duration of the subject's participation in the study. The study
number and subject number in all supporting documents (such as laboratory records or hospital
records) submitted along with the eCRF should be carefully verified. All personal privacy
information (including the name of the subject) should be deleted or be made indecipherable in
order to protect subject privacy.
The investigator could be automatically added to the eCRF with his/her user ID. The investigators
verify that the record have been reviewed and that the data are accurate with an electronic
signature. The electronic signature is completed with the investigator's user ID and password.
The system automatically attaches the date and time of the signature. The investigator could not
share the user ID and password with other personnel. If data in the eCRF need to be modified,
the procedures defined by the EDC system have to be followed. All modifications and reasons
for the changes are recorded in the audit trail.
Training on the EDC system will be provided to study personnel at the study site.
Adverse events, and concurrent diseases/medical history will be coded. The medical dictionary
used for coding will be described in the Clinical Study Report (CSR).
9.3 Audits and Inspections
The sponsor or its representative (WuXi Clinical Co., Ltd) may conduct quality assurance audits
on the study site, database, and relevant study-related documents. Also, regulatory authorities
may also decide to inspect the study site, database, and relevant study-related documents at its
own discretion. The aim of audits and inspections is to systematically and independently check
all study-related procedures and documents to ensure that the clinical study is being carried out
in accordance with requirements of the trial protocol, GCP, Declaration of Helsinki, and
applicable regulations. The investigator must inform the sponsor immediately when an
inspection notice is received from the regulatory authorities.

independent ethics committee (IEC) of each study site. The trial protocol, informed consent form
(ICF), investigators brochure, subject recruitment material or advertisements (if applicable), as
well as other documents required by regulations must be submitted to the IEC for approval. Prior
to the start of the study, written approval from the IEC must be obtained and provided to the
sponsor. The IEC approval must clearly state the title, number, and version of the study protocol
as well as the version of other documents (e.g. ICF) and the date of approval. The investigator
must notify the sponsor of the IEC's written comments concerning delays, suspension and re-
approval.
The study site must follow the requirements of the IEC. IEC requirements may include
submitting the revised protocol, ICF, or subject recruitment material to the IEC for approval,
local regulatory requirements for safety reports, and regular reports, updates, and submitting the
final report as per IEC requirements. The above documents as well as the IEC approval must be
provided to the sponsor or its designated personnel.
10.2 Implementation of Ethical Principles
The study process and the acquisition of informed consent should comply with the Declaration of
Helsinki, relevant GCP requirements (CPMP/ICH/135/95), and applicable statutes and
regulations related to drugs and data protection in the country in which the study is conducted.
The GCP is an international ethical and scientific quality standard for designing, conducting,
recording and reporting clinical trials that involve the participation of human subjects. To protect
the rights, safety, and healthy of subjects, this study will be carried out in accordance with GCP
and applicable national regulations, as well as ethical principles outlined in the Declaration of
Helsinki.

10.3 Subject Information and Informed Consent
Prior to undergoing any study procedure, the ICF should be used to explain to potential participants
the potential risks and benefits of this study. The informed consent form should be in a language
that is simple and be easy to understand. The ICF should state that informed consent is voluntary,
emphasize the potential risks and benefits of participating in this study, and that the subject may
withdraw from the study at any time. The investigator may only enroll a subject after fully
explaining the details of the study, answering questions to the subject's satisfaction, giving
the subject sufficient time for consideration, and obtaining written consent from the subject or
his/her legal representative. All signed ICF must be retained in the investigator's documents or
the subject's folder.
The investigator is responsible for explaining the contents of the ICF and obtaining the ICF
signed and dated by the subject or his/her legal representative prior to starting the study. The
investigator should provide the subject with a copy of the signed ICF. The investigator must
document the informed consent process in the source document of the trial.
10.4 Protection of Subject Data
Information about data protection and privacy protection will be included in the ICF (or in some
cases, in a separate document).
Study personnel must ensure that the privacy of clinical trial subjects are protected. In all
documents submitted to the sponsor, the clinical trial subjects must only be identified with
subject number and not with the full name.
Additional precautions should be taken to ensure the confidentiality of the documents and
to prevent the identification of subjects based on genetic data. However, under special
circumstances, some personnel may be permitted to see the genetic data and personal
identification number of a subject. For example, in the event of a medical emergency, the
sponsor, designated physician, or investigator will have access to the subject identification code
and the subject's genetic data. In addition, regulatory agencies may request access to relevant
documents.

MEASURABILITY OF TUMOR AT BASELINE
1.1
Definitions
At baseline, tumor lesions/lymph nodes will be categorized as measurable or not measurable as
follows:
1.1.1
Measurable
Tumor lesions: must be accurately measured in at least one dimension (longest diameter in the
plane of measurement is to be recorded) with a minimum size of:

10 mm by CT scan (CT scan slice thickness no greater than 5 mm)

10 mm caliper measurement by clinical exam (lesions which cannot be accurately
measured with calipers should be documented as not measurable).

20 mm by chest X-ray.
Malignant lymph nodes: To be considered pathologically enlarged and measurable, a lymph
node must be ≥15 mm in short axis when assessed by CT scan (CT scan slice thickness
recommended to be no greater than 5 mm). At baseline and in follow-up, only the short axis will
be measured and followed.
1.1.2
Not measurable
All other lesions, including small lesions (longest diameter <10 mm or pathological lymph nodes
with a short axis ≥10 and <15 mm) as well as truly not measurable lesions. Lesions considered
truly not measurable include: leptomeningeal disease, ascites, pleural or pericardial effusion,
inflammatory breast disease, lymphangitis involving the skin or lungs, abdominal masses/
abdominal organomegaly identified by physical exam but not measurable by reproducible
imaging techniques.
1.1.3
Special considerations regarding measurable bone lesions, cystic lesions, and lesions
with prior locoregional treatment:
Bone lesions:

Bone scan, PET scan or plain films are not considered adequate imaging
techniques to measure bone lesions. However, these techniques can be used to
confirm the presence or disappearance of bone lesions.


Lytic bone lesions or mixed lytic-blastic lesions, with identifiable soft tissue
components, that can be evaluated by cross sectional imaging techniques (such as
CT or MRI) can be considered as measurable lesions if the soft tissue
components meet the definition of measurability described above.

Blastic bone lesions are not measurable.
Cystic lesions:

Lesions that meet the criteria for radiographically defined simple cysts should not
be considered as malignant lesions (neither measurable nor not measurable) since
they are, by definition, simple cysts.

‘Cystic lesions’ thought to represent cystic metastases can be considered as
measurable lesions, if they meet the definition of measurability described above.
However, if noncystic lesions are present in the same patient, these noncystic
lesions are preferred for selection as target lesions.
Lesions with prior locoregional treatment:

Tumor lesions situated in a previously irradiated area or in an area subjected to
other locoregional therapy are usually not considered measurable, unless there
has been demonstrated progression in the lesion. The study protocol should detail
the conditions under which such lesions would be considered measurable.
1.2
Specifications by Methods of Measurements
1.2.1
Measurement of lesions
All measurements should be documented with metric symbols. Calipers should be used if clinical
assessments are required. All baseline evaluations should be performed as close as possible to
the beginning of the treatment but never more than 4 weeks before the beginning of the treatment.
1.2.2
Method of assessment
The same method of assessment and the same technique should be used to characterize each
identified and reported lesion at baseline and during follow-up. Imaging evaluation should
always be done rather than clinical examination unless the lesion(s) being followed cannot be
imaged but are assessable by clinical examination.
Clinical lesions: Clinical lesions will only be considered measurable when they are superficial
and its diameter is ≥10 mm as assessed using calipers (e.g. skin nodules). For skin lesions,
documentation by color photography including a plotting scale to estimate the size of the lesion
is recommended. As noted above, when lesions can be evaluated by both clinical examination
and imaging evaluation, the latter should be undertaken since it is more objective and may also

be reviewed at the end of the study.
Chest X-ray: Chest CT is preferred over chest X-ray, particularly when progression is an
important endpoint, since CT is more sensitive than X-ray, particularly in identifying new lesions.
However, lesions on chest X-ray may be considered measurable if they have clear boundaries
and are surrounded by aerated lung tissues.
CT and MRI: CT is the best currently available and reproducible method to measure lesions
selected for response assessment. This guideline has defined measurability of lesions on CT scan
based on the assumption that CT slice thickness is 5 mm or less. When CT scans have a slice
thickness greater than 5 mm, the minimum size for a measurable lesion should be twice the slice
thickness. MRI is also acceptable in certain situations (e.g. for body scans).
Ultrasound: Ultrasound should not be used for measuring lesion size and should not be used as
a method of measurement. Ultrasound examinations cannot be reproduced in their entirety for
independent review at a later date and, because they are operator dependent, it cannot be
guaranteed that the same technique and measurements will be taken from one assessment to the
next. If new lesions are identified by ultrasound in the course of the study, confirmation by CT
or MRI is recommended. If there is concern about radiation exposure at CT, MRI may be used
instead of CT in selected instances.
Endoscopy and laparoscopy: The utilization of these techniques is not recommended for
objective tumor evaluation. However, they can be used to confirm complete pathological
response when biopsies are obtained or to determine relapse in trials where recurrence following
complete response or surgical resection is an endpoint.
Tumor markers: Tumor markers alone cannot be used to assess objective tumor response. If
markers are initially above the upper limit of normal, however, they must normalize for a patient
to be considered in complete response. Because tumor markers are disease specific, instructions
for their measurement should be incorporated into the protocol on a disease specific basis.
Specific guidelines for both CA-125 response (in recurrent ovarian cancer) and PSA response
(in recurrent prostate cancer) have been published. In addition, the Gynecologic Cancer
Intergroup has developed CA125 progression criteria which are to be integrated with objective
tumor assessment for use in first-line trials in ovarian cancer.
Cytology and histology: These techniques can be used to differentiate between PR and CR in rare
cases if required by the protocol (for example, residual lesions in tumor types such as seminoma,
where known residual benign tumors can remain). When effusions are known to be a potential
adverse effect of treatment (e.g. with certain taxane compounds or angiogenesis inhibitors),
cytological confirmation of the neoplastic origin of any effusion that appears or worsens during

treatment can be considered if the measurable tumor has met criteria for response or stable
disease in order to differentiate between response (or stable disease) and progressive disease.
2.
TUMOR RESPONSE EVALUATION
2.1
Assessment of Overall Tumor Burden and Measurable Disease
To assess objective response or future progression, it is necessary to estimate the overall tumor
burden at baseline and use this as a comparator for subsequent measurements. Only patients with
measurable disease at baseline should be included in regimens where objective tumor response is
the primary endpoint. Measurable disease is defined by the presence of at least one measurable
lesion. In studies where the primary endpoint is tumor progression (either time to progression or
proportion with progression at a fixed date), the protocol must specify if entry is restricted to
those with measurable disease or whether patients having non-measurable disease only are also
eligible.
2.2
Baseline Documentation of "Target" and "Non-Target" Lesions
When more than one measurable lesion is present at baseline, all lesions (five lesions at most,
and two lesions per organ at most) representative of all involved organs should be identified as
target lesions and will be recorded and measured at baseline (This means in instances where
patients have only one or two organ sites involved, a maximum of two and four lesions
respectively will be recorded).
Target lesions should be selected on the basis of their size (lesions with the longest diameter), be
representative of all involved organs, and should be those with reproducible repeated
measurements. It may be the case that, the largest lesion does not have reproducible
measurements, in which circumstance the next largest lesion with reproducible measurements
should be selected.
Lymph nodes merit special mention since their normal anatomical structures may be visible by
imaging even if not involved by tumor. Pathological nodes which are defined as measurable and
may be identified as target lesions must have a short axis of ≥15 mm by CT scan. Only the short
axis of these nodes will contribute to the baseline sum. The short axis of the node is the diameter
normally used by radiologists to judge if a node is invaded by solid tumor. Nodal size is
normally reported as two dimensions in the plane in which the image is obtained (for CT scan
this is almost always the axial plane; for MRI the plane of acquisition may be axial, sagittal or
coronal). The smaller of these measures is the short axis. For example, an abdominal node which
is reported as being 20 mm × 30 mm has a short axis of 20 mm and qualifies as a malignant
measurable node. In this example, 20 mm should be reported as the node measurement. All other
pathological nodes (those with a short axis ≥10 mm but < 15 mm) should be considered non-

target lesions. Lymph nodes that have a short axis < 10 mm are considered non-pathological and
should not be recorded or followed.
A sum of the diameters (longest for non-nodal lesions; short axis for nodal lesions) for all target
lesions will be calculated and reported as the baseline sum of diameters. If lymph nodes are to be
included in the sum, then as noted above, only the short axis is added into the sum. The baseline
sum of diameters will be used as reference to further characterize any objective tumor regression
in the measurable dimension of the disease.
All other lesions (or sites of disease) including pathological lymph nodes should be identified as
non-target lesions and should also be recorded at baseline. Measurements are not required and
these lesions should be recorded as "present", "absent", or in rare cases "unequivocal
progression". In addition, it is possible to record multiple target lesions involving the same organ
as a single item on the case record form (e.g. ‘multiple enlarged pelvic lymph nodes’ or ‘multiple
liver metastases’).
2.3
Response Criteria
2.3.1
Evaluation of target lesions
Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes
(whether target or non-target) must have a reduced short axis of <10 mm.
Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions vs. the
baseline sum of diameters.
Progressive Disease (PD): At least a 20% increase in the sum of diameters of target lesions vs.
the smallest sum during the study (this includes the baseline sum if that is the smallest). In
addition to the relative increase of 20%, the sum must also have an absolute increase of at least
5 mm. (Note: The appearance of one or more new lesions is also considered progression).
Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to
qualify for PD, using the smallest sum of diameters during the study as reference.
2.3.2
Special notes on the assessment of lymph nodes which are target lesions
Lymph nodes identified as target lesions should always have the actual short axis measurement
recorded (measured in the same anatomical plane as during the baseline examination), even if the
nodes regress to below 10 mm at the time of the study. This means that when lymph nodes are
included as target lesions, the "sum" of lesions may not be zero even if complete response
criteria are met, since a normal lymph node is defined as having a short axis of <10 mm. Case
report forms or other data collection methods may therefore be designed to have target nodal
lesions recorded in a separate section where, in order to qualify for CR, each node must have a

short axis of <10 mm. For PR, SD, and PD, the actual short axis measurement of the nodes is to
be included in the sum of target lesions.
Target lesions that are "too small to measure". During the study, all lesions (nodal and non-
nodal) recorded at baseline should have their actual measurements recorded at each subsequent
evaluation, even when very small (e.g. 2 mm). However, sometimes lesions or lymph nodes
which are recorded as target lesions at baseline become so faint on CT scan that the radiologist
may not feel comfortable assigning an exact measurement and may report them as being "too
small to measure". When this occurs it is important that a value be recorded on the case report
form. If it is the opinion of the radiologist that the lesion has probably disappeared, the
measurement should be recorded as 0 mm. If the lesion is believed to be present and is faintly
seen but too small to measure, a default value of 5 mm should be assigned (Note: It is less likely
that this rule will be used for lymph nodes since they usually have a definable size when normal
and are frequently surrounded by fat such as in the retroperitoneum; however, if a lymph node is
believed to be present and is faintly seen but too small to measure, a default value of 5 mm
should be assigned in this circumstance as well). This default value is derived from the 5 mm CT
slice thickness (but should not be changed with varying CT slice thickness). The measurements
of these lesions are potentially non-reproducible, therefore providing this default value will
prevent false responses or progressions caused by measurement errors. To reiterate, however, if
the radiologist is able to provide an actual measurement, that value should be recorded, even if it
is below 5 mm.
Lesions that split or coalesced at the time of treatment. When non-nodal lesions fragment, the
longest diameters of the fragmented portions should be added together to calculate the target lesion sum.
Similarly, as lesions coalesce, a plane between them may be maintained that would aid in obtaining
maximal diameter measurements of each individual lesion. If the lesions have truly coalesced such that
they are no longer separable, the vector of the longest diameter in this instance should be the maximal
longest diameter for the "coalesced lesion".
2.3.3
Evaluation of non-target lesions
This section provides the definitions of the criteria used to determine the tumor response for the
group of non-target lesions. While some non-target lesions may actually be measurable, they do
not need to be measured and instead should be assessed only qualitatively at the time points
specified in the protocol.
Complete Response (CR): Disappearance of all non-target lesions and normalization of tumor
marker level. All lymph nodes must be non-pathological in size (short axis <10 mm).
Non-CR/Non-PD: Persistence of one or more non-target lesion(s) and/or maintenance of tumor
marker level above the normal limits.

Progressive Disease (PD): Unequivocal progression of existing non-target lesions. (Note: The
appearance of one or more new lesions is also considered progression).
2.3.4
Special notes on the assessment of progression of non-target lesions
The concept of progression of non-target disease requires additional explanation as follows: When
the patient also has measurable lesions. In this setting, to achieve ‘unequivocal progression’ on the
basis of the non-target lesion, there must be an overall level of substantial worsening in non-target
disease such that, even in the presence of SD or PR of the target disease, the overall tumor burden
has increased sufficiently to merit discontinuation of therapy. A minimal increase in the size of one
or more non-target lesions is usually not sufficient to quality for unequivocal progression status.
The designation of overall progression solely on the basis of change in non-target lesions in the
face of SD or PR of target disease will therefore be extremely rare.
When the patient has only lesions that are not measurable. This circumstance arises in some
phase III trials when the presence of measurable lesions is not a criterion for study enrollment.
The same general concepts apply here as well. However, in this instance there are no measurable
lesions to factor into the interpretation of an increase in non-measurable lesion burden. Because
worsening in non-target lesion cannot be easily quantified (by definition: if all lesions are truly
not measurable), a useful test that can be applied when assessing patients for unequivocal
progression is to consider if the increase in overall lesion burden based on the change in non-
measurable disease is comparable in magnitude to the increase that would be required to declare
PD for measurable disease: i.e. an increase in tumor burden representing an additional 73%
increase in volume (which is equivalent to a 20% increase of diameter in a measurable lesion).
Examples include an increase in pleural effusion from "trace" to "large amount", an increase in
lymphangitic lesion from localized to widespread, or a description in the protocol such as
"sufficient to require a change in therapy". If ‘unequivocal progression’ is seen, the patient
should be considered to have had overall PD at that point. While it would be ideal to have
objective criteria to apply to diseases that are not measurable, the very nature of these diseases
makes it impossible to do so, therefore the increase must be substantial.
2.3.5
New lesions
The appearance of new malignant lesions denotes disease progression; therefore, some
comments on the detection of new lesions are important. There are no specific criteria for the
identification of new radiographic lesions; however, the finding of a new lesion should be
unequivocal: i.e. not attributable to differences in scanning technique, change in imaging
modality or findings thought to represent something other than tumors (for example, some new
bone lesions which may be simply healed or flare of pre-existing lesions). This is particularly

Confidential
important when the patient’s baseline lesions show partial or complete response. For example,
necrosis of a liver lesion may be reported by a CT scan as a "new" cystic lesion, while it is
actually not.
A lesion identified during a follow-up in an anatomical location that is not discovered during the
baseline scan is considered a new lesion and will indicate disease progression. For example, a
patient with a visceral disease at baseline has a brain CT or MRI which reveals metastases. The
patient's brain metastases are considered evidence of PD even if he/she does not have brain
imaging at baseline.
If a new lesion is equivocal, for example because of its small size, continued therapy and follow-
up evaluation will clarify if it represents a truly new lesion. If repeat scans confirm there is
definitely a new lesion, then progression should be declared using the date of the initial scan.
While FDG-PET response assessments need additional studies, it is sometimes reasonable to
incorporate the use of FDG-PET scanning to complement CT scanning in assessment of
progression (particularly possible "new" lesions). New lesions on the basis of FDG-PET imaging
can be identified as follows:
a.
A negative FDG-PET at baseline and a positive FDG-PET at follow-up is a sign of PD
based on a new lesion.
b.
No FDG-PET at baseline and a positive FDG-PET at follow-up:
If the positive FDG-PET at follow-up corresponds to a new lesion site confirmed by
CT, this is PD. If the positive FDG-PET at follow-up is not confirmed as a new lesion
site on CT, additional follow-up CT scans are needed to determine if there is truly
progression at that site (if so, the date of PD will be the date of the initial abnormal
FDG-PET scan). If the positive FDG-PET at follow-up corresponds to a pre-existing
lesion site on CT that is not progressing according to the anatomic images, this is not PD.
2.4
Evaluation of Best Overall Response
The best overall response is the best response recorded from the start of the study treatment until
the end of treatment, taking into account any requirement for confirmation. On occasion a
response may not be documented until after the end of therapy, so the study protocol should
clearly state if post-treatment assessments are to be considered when determining best overall
response. The study protocol must specify how any new therapy introduced before progression
will affect best response designation. Assignment of best overall response for the patient will
depend on the findings of both target and non-target lesions and will also take into consideration
the appearance of new lesions. Furthermore, depending on the nature of the study and the

Confidential
protocol requirements, confirmatory measurement may also be required. Specifically, in non-
randomized trials where response is the primary endpoint, confirmation of PR or CR is needed to
determine which one is the "best overall response".
2.4.1
Time point response
It is assumed that at each time point specified by the study protocol, a response assessment
occurs. Table 1 on the next page provides a summary of the overall response status calculation at
each time point for patients who have measurable disease at baseline.
When patients have non-measurable (therefore non-target) disease only, Table 2 is to be used.
2.4.2
Missing assessments and non-evaluable targets
When no imaging/measurement is done at a particular time point, the patient is not evaluable
(NE) at that time point. If only a subset of lesion measurements are made at an assessment,
usually the case is also considered NE at that time point, unless a convincing argument can be
made that the missing lesion(s) would not change the response at the assigned time point. This
would be most likely to happen in the case of PD. For example, if a patient have a baseline sum
of 50 mm with three measured lesions and at follow-up only two lesions are assessed and with
a sum of 80 mm, the patient will have achieved PD status, regardless of the contribution of the
missing lesion.
2.4.3
Best overall response: all time points
The best response is determined once all the data for the patient is obtained.
Best response determination in trials where confirmation of complete or partial response is not
required: Best response in these trials is defined as the best response across all time points (for
example, the best overall response of a patient who has SD at the first assessment, PR at the
second, and PD at the last is PR). When SD is believed to be best response, it must also meet the
minimum time from baseline specified by the protocol. If the minimum time is not met,
otherwise SD is the best time point response, the patient’s best response depends on subsequent
assessments. For example, if a patient has SD at the first assessment, PD at the second and does
not meet the minimum duration for SD, his/her best response is PD. The same patient lost to
follow-up after the first SD assessment would be considered not evaluable.
Best response determination in trials where confirmation of complete or partial response is
required: Complete or partial responses may be claimed only if the criteria for each are met at a
subsequent time point specified in the protocol (generally 4 weeks later). In this circumstance,
the best overall response can be interpreted as in Table 3.

2.4.4
Special notes on response assessment
When nodal lesions are included in the sum of target lesions and the nodes decrease to "normal"
size (<10 mm), they may still have a measurement reported on scans. This measurement should
be recorded even if the nodes are normal in size in order not to overstate progression should it be
based on the increase in size of the nodes. As noted earlier, this means that patients with CR may
not have a total sum of "zero" on the case report form (CRF).
In trials where confirmation of response is required, repeated "NE" time point assessments may
complicate best response determination. The analysis plan for the trial must explain how missing
data/assessments will be addressed in the determination of response and progression. For
example, in most trials it is reasonable to consider a patient with time point responses of PR-NE-
PR as a confirmed response.
Patients with a global deterioration of health status requiring discontinuation of treatment without
objective evidence of disease progression at that time should be reported as "symptomatic
deterioration". Every effort should be made to document objective progression even after
discontinuation of treatment. Symptomatic deterioration is not a descriptor of an objective
response. Instead, it is a reason for stopping the study treatment. The objective response status of
this type of patients is to be determined by evaluation of target and non-target lesions as shown
in Table 1–3.
Conditions that define "early progression, early death, and non-evaluability" are study specific
and should be clearly described in each study protocol (depending on treatment duration and
treatment periodicity).
In some circumstances it may be difficult to distinguish a residual lesion from normal tissues.
When the evaluation of complete response depends upon this determination, it is recommended
that the residual lesion be investigated (by fine needle aspirate/biopsy) before assigning a status
of complete response.
Like a biopsy, FDG-PET may also be used to upgrade a response to a CR in cases where a
residual radiographic abnormality is thought to represent fibrosis or scarring. The use of FDG-
PET in this circumstance should be pre-defined in the protocol and supported by disease specific
medical literature for the indication. However, it must be acknowledged that both approaches
may lead to false positive CR due to limitations of FDG-PET and biopsy resolution/sensitivity.

a "Non-CR/non-PD" is preferred over "stable disease" for non-target disease, since SD is increasingly used as an
endpoint for assessment of efficacy in some trials, thus assigning this category in the absence of measurable
lesions is not advised.
For equivocal findings of progression (e.g. very small and uncertain new lesions; cystic changes
or necrosis in existing lesions), treatment may continue until the next scheduled assessment. If at
the next scheduled assessment, progression is confirmed, the date of progression should be the
earlier date when progression is suspected.

a If CR is truly achieved at the first time point, then any lesions seen at a subsequent time point, even those meeting
PR criteria relative to baseline, make the disease PD at that time point (since lesions must have reappeared after
CR). Best response would depend on whether the minimum duration for SD is met. However, sometimes CR may
be claimed and subsequent scans suggest small lesions are likely still present, while in fact the patient have PR
instead of CR at the first time point. Under these circumstances, CR should be changed to PR and the best response
is PR.
2.5 Frequency of Tumor Re-Evaluation
Frequency of tumor re-evaluation during treatment should be protocol specific and adapted to the
type and schedule of treatment. However, for phase II studies where the beneficial effect of the
treatment is not known, follow-up every 6–8 weeks (timed to coincide with the end of a cycle) is
reasonable. Smaller or greater time intervals may be justified for certain regimens or circumstances.
The study protocol should specify which organ sites are to be evaluated at baseline (usually those
most likely to be involved with metastatic disease for the tumor type under study) and how
often evaluations are repeated. Normally, all target and non-target sites are evaluated at each
assessment. Under certain circumstances, some non-target organs may be evaluated less frequently.
For example, bone scans may need to be repeated only when complete response is identified in
the target lesion or when progression is suspected.

After the end of the treatment, the need for repeated tumor evaluations depends on whether the
trial has a goal such as a certain response rate or a certain time to an event (progression/death).
If ‘time to an event’ (e.g. time to progression, disease-free survival, progression-free survival) is
the main endpoint of the study, then routine scheduled re-evaluation of lesion sites specified by
the protocol must be carried out. In randomized comparative trials in particular, the scheduled
assessments should be performed on time (for example: every 6–8 weeks during the treatment or
every 3–4 months after the treatment) and should not be affected by treatment delays, holidays or
any other events that might lead to imbalance in the timing of disease assessment between
treatment arms.
2.6 Confirmation of Measurements/Duration of Response
2.6.1 Confirmation
In non-randomized trials where response is the primary endpoint, confirmation of PR and CR is
required to ensure responses identified are not the result of measurement errors. This will also
permit appropriate interpretation of results in the context of historical data. Response
confirmation has been traditionally required in such trials. However, in all other circumstances,
i.e. in randomized trials (phase II or III) or studies where stable disease or progression are the
primary endpoints, confirmation of response is not required since it will not add value to the
interpretation of trial results. However, elimination of the requirement for response confirmation
may increase the importance of central review to protect against bias, in particular in studies
which are not blinded.
In the case of SD, measurements after study entry must have met the minimum interval for SD
(generally not shorter than 6–8 weeks) defined in the study protocol at least once.
2.6.2 Duration of overall response
The duration of overall response is measured from the time CR/PR measurement criteria are first
met CR/PR (whichever is first documented) until the date when recurrent or progressive disease
is objectively documented for the first time (using the shortest time to progressive disease
documented during the study as reference).
The duration of overall complete response is measured from the time CR measurement criteria
are first met until the date when recurrent disease is objectively documented for the first time.
2.6.3 Duration of stable disease
Stable disease is measured from the start of the treatment (in randomized trials, from the date
of randomization) until the criteria for progression are met, using the smallest sum during the
study as reference (if the baseline sum is the smallest, then it is used as the reference for the
calculation of PD).

The clinical relevance of the duration of stable disease varies with different studies and diseases.
If the proportion of patients achieving stable disease for a minimum period of time is an endpoint
of importance in a particular trial, the protocol should specify the minimal time interval required
between two measurements for the determination of stable disease.
Note: The duration of response and stable disease as well as the progression-free survival are
influenced by the frequency of follow-up after baseline evaluation. It is not in the scope of th
guidelines to define a standard follow-up frequency. The frequency should take into account
many parameters including disease types and stages, treatment periodicity, and standard practice.
However, limitations of the precision of the measured endpoint should be taken into account if
comparisons between trials are to be made.
