Brief summary:
The study is to evaluate ORR, CR, PR DCR DOR PFS and safety of IBI308 in treatment of patients with Relapsed/Refractory Hodgkin's Lymphoma.

Detailed description:
Patients with classical Hodgkin lymphoma(cHL) who relapse after autologous stem-cell transplantation(ASCT) or progress after multiple lines of chemotherapy have a poor prognosis, with a median survival of approximately 1.2 years.

CHL frequently harbors a spectrum of chromosome 9p24.1/PD-L1/PD-L2 alterations, leading to overexpression of the programmed death 1 ligands,PD-L1 and PD-L2.

Sintilimab is a humanized monoclonal antibody against PD-1 that blocks the interaction between PD-1 and its ligands and was approved for relapsed/refractory Hodgkin lymphoma in China in 2018.

This study is a single arm,phase 2 study designed to evaluate the clinical activity of sintilimab in Chinese patients with R/R

Study Design 
This study is a multicenter, single-arm, phase II study to evaluate the 
efficacy and safety of IBI308 in relapsed or refractory classic Hodgkin's 
lymphoma. This study will enroll patients with relapsed or refractory cHL to 
receive intravenous (IV) IBI308 at 200 mg every three weeks (Q3W) for up 
to 24 months, or until disease progression, death, unacceptable adverse 
event(s), subject withdraws informed consent or other reasons specified in 
protocol. If the subject still has no disease progression after 24 months of 


IBI308 
Innovent Biologics 
CIBI308B201

IBI308 treatment and the investigator judges that the subject will still benefit 
from the study drug, the subject should sign additional informed consent to 
continue receiving free IBI308 treatment. For subjects with first disease 
progression, if the clinical condition is stable, the investigator may let the 
subject continue to receive treatment until the total treatment time reaches 
24 months or until disease progression, death, unacceptable adverse 
event(s), subject withdraws informed consent, or other reasons specified in 
protocol. 
The primary endpoint of the study is overall response rate (ORR), defined as 
the percentage of subjects with optimal response to partial and complete 
response, evaluated according to the IWG 2007 criteria, and the Lugano 
2014 criteria as an adjunct to the standard, both evaluated by IRRC. 
Analysis of primary endpoints will be performed after the last subject who 
meets the statistical and imaging assessment requirements and completes up 
to 24 weeks of follow-up. Subjects will have a safety follow-up 90 days 
after the last dose of IBI308.

time reaches 24 months or recurrence of disease progression, death, toxicity intolerance, withdrawal of informed consent. Or other reasons specified by the program. 
18. The quality of life assessment was assessed using the EQ-5D-5L and EORTC QLQ-C30 scales on the day of the first dose, each imaging assessment, and the end of treatment visit. 
19. Subjects who meet the inclusion criteria are required to provide archived tumor tissue at baseline or 4 unstained 4-5 micron sections prepared freshly during the screening period for PD-
L1 testing. For the detection of mRNA expression of immune-related genes, subjects should provide as much as possible of the archived tumor tissue at baseline or 4 unstained 4~5 
micron sections prepared freshly during the screening period.  
20. Subjects are required to provide 10 ml whole blood samples at the following time points: before the first dose, during the treatment period, and before the next treatment.  
21. Treatment termination: Treatment termination includes early termination (in addition to disease progression leading to discontinuation of the drug) and study treatment (end of disease 
leading to discontinuation of the drug), and treatment termination at the end of treatment. For patients who discontinued treatment for reasons other than imaging disease progression, an 
imaging evaluation was performed every 12 weeks (±7 days) after discontinuation of the drug until one of the following events occurred: initiation of new anti-tumor therapy, disease 
progression, subject withdrawal of ICF and death.

1 Background 
Disease Background 
As a malignancy originating from the lymphatic hematopoietic system, lymphoma can 
be classified into two categories, namely Hodgkin lymphoma and non-Hodgkin 
lymphoma according to pathologic character. In 2015, 88000 estimated new cases of 
lymphoma were diagnosed in China [1]. Based on morphology and immunophenotype, 
Hodgkin lymphoma is divided into two categories: nodular lymphocyte predominant 
Hodgkin lymphoma and classical Hodgkin lymphoma (cHL). The latter is further 
divided into four types, i.e. lymphocyte rich, mixed cellularity, nodular sclerosing and 
lymphocyte depleted [4]. According to a pathological analysis of 10002 Chinese 
lymphoma patients, the proportion of Hodgkin lymphoma was 8.54%, of which cHL 
accounted for 93.56% [3]. The cure rate after first-line treatment of Hodgkin lymphoma 
is approximately 85% [4], and the rest 15% are considered refractory or have a tendency 
to relapse. For relapsed or refractory cHL, the second-line standard treatment in Europe 
and the United States is high-dose chemotherapy combined with autologous 
hematopoietic stem cell transplantation [5]. Due to the low acceptance of transplant 
therapy and limited medical resources in China, the second-line treatment for relapsed 
or refractory cHL patients is chemotherapy in general. According to historical data, the 
rate of non-treatment failure three years after second-line chemotherapy is 34%, and 
this rate three years after second-line high-dose chemotherapy in combination with 
autologous hematopoietic stem cell transplantation was 55% [6, 7]. High quality evidence 
is still lacking for third-line therapy or above [5]. Currently, monotherapy includes 
Brentuximab Vedotin [8], bendamustine [9], lenalidomide [10] and everolimus [11]. 
Brentuximab Vedotin showed an ORR of 75% and a PFS of 5.6 months in 102 patients 
who failed high-dose chemotherapy combined with autologous hematopoietic stem cell 
transplantation [8]. It has not been approved in China yet. Bendamustine had an ORR 
of 56% and a DOR of 5 months in 36 patients who had failed an average of four lines 
of therapy [9]. Lenalidomide demonstrated 19% of ORR and 4 months of PFS in 38 
patients who had failed an average of four lines of therapy [10]. Of the 19 patients who 
failed an average of six line treatment, everolimus showed an ORR of 47%, and time 
to progression of 7.2 months [11]. The ORR of the above single regimen was between 
19-56%, however, the disease control duration was short. Therefore, there is a 
significantly unmet clinical need for relapsed or refractory cHL which progress beyond 
second-line therapy in China.

The PD-1/PD-L1 pathway may play an important role in the onset and progression of 
cHL. The rate of  PD-L1 expression in Reed Sternberg cell (RS cell) of cHL was 65% 
in nodular sclerosing type (87/134), 81% in mixed cellularity type (60/74), 90% in 
lymphocyte rich type (9/10) and 67% in lymphocyte depleted type (4/6) [12]. High 
expression of PD-L1 in RS cells in cHL is usually caused by a copy number abnormality 
at the 9p24.1 site, which contains the PD-L1, PD-L2 and JAK2 genes. In a study of 108 
patients with cHL, FISH was used to detect PD-L1 and its copy number. Polyploid, 
copy number increase and copy number amplification were 5% (5/108), 61% (56/108) 
and 39% (36/108) respectively [13]. JAK2 activates downstream transcription factor 
STAT and further increases PD-L1 expression [14]. In addition, EB virus infection can 
also cause an increase in PD-L1 expression [15]. Since the expression of PD-L1 can 
cause immune escape of RS cells, blocking the signal pathway of PD-L1/PD1 may 
relieve immune suppression and promote the clearance of RS cells by immune system. 
Anti-PD-1 monoclonal antibodies Nivolumab and Pembrolizumab have shown 
significant efficacy in cHL [16, 17]. In patients who failed high-dose chemotherapy in 
combination with autologous hematopoietic stem cell transplantation and Brentuximab 
Vedotin, the ORR of Pembrolizumab was 72.5% (50/69). In patients who are not 
suitable for high dose chemotherapy or autologous hematopietic stem cell 
transplantation, the ORR of Pembrolizumab was 65.4% (53/81) after failure of 
Brentuximab Vedotin [18]. The ORR of Nivolumab in patients who failed high-dose 
chemotherapy in combination with autologous hematopoietic stem cell transplantation 
and Brentuximab Vedotin was 66.3% (53/80) [17]. Currently, Nivolumab has been 
approved by the US FDA for cHL patients who have failed high-dose chemotherapy 
combined with autologous hematopoietic stem cell transplantation and Brentuximab 
Vedotin. 
Nivolumab and Pembrolizumab have shown significant efficacy in cHL patients who 
have failed multi-line therapy, demonstrating the effectiveness of blocking PD-1/PD-
L1 pathway in relapsed and refractory cHL. To this end, this clinical trial is designed to 
evaluate the efficacy and safety of IBI308 in relapsed and refractory cHL. 
Tested Drug (IBI308) 
Mechanism of IBI308 
Immune checkpoints are a group of immunosuppressive molecules with the 
physiological function of regulating the intensity and breadth of immune response, 
thereby avoiding damage of normal tissues. Tumor cells can express these immune 
checkpoint molecules to escape immune attacks. Currently validated immune 
checkpoints include CTLA-4 and PD1/PD-L1. With its safety profile and broad 
indications, monoclonal antibody targeting PD1/PD-L1 pathway has shown promising 
prospect. 
PD-1 is mainly expressed on activated T cells, with two ligands being PD-L1 and PD-
L2. PD-L1 is its main ligand, which is expressed on activated T cells, antigen presenting 
cells and tumor cells as well [19]. The binding of PD-1/PD-L1 plays an important role 


IBI308 
Innovent Biologics 
CIBI308B201 
21 
 
in regulation of T cell activation and peripheral immune tolerance. When not expressing 
PD-1, T cells interact with antigen-presenting cells, proliferate and secrete activating 
cytokines, and exert tumoricidal effect. After activation, T cells will express PD-1. 
When binding with PD-L1 on tumor cells, the inhibitory signal will prevent T cell from 
further activation and secretion of activating cytokines, causing immune escape and 
cancer progression. By blocking the interaction between PD-1 and PD-L1, the 
tumoricidal capability of T cell will be restored [20]. 
So far, the US FDA has approved the listing of three PD-1/PD-L1 products, namely 
Bristol-Myers Squibb (BMS) anti-PD-1 monoclonal antibody Nivolumab (trade name: 
OPDIVO), Merck Anti-PD-1 mAb Pembrolizumab (trade name: KEYTRUDA), and 
Genetech anti-PD-L1 monoclonal antibody Atezolizumab (trade name: Tecentriq). The 
indications include advanced melanoma, advanced NSCLC, advanced cHL, advanced 
renal cell renal cell carcinoma and urothelial carcinoma, advanced head and neck cancer. 
In addition, several other indications are currently under Phase III clinical trials or 
application. The listing of the above drugs has established the important position of PD-
1/PD-L1 immune checkpoint inhibitors in tumor immunotherapy. At present, there is 
no PD-1/PD-L1 immune checkpoint inhibitor listed in China. It is of great significance 
to develop such monoclonal antibodies to improve the outcome of advanced cancer 
patients in China. 
Recombinant human-derived anti-PD-1 monoclonal antibody injection (R&D code: 
IBI308) is a recombinant human-derived IgG4 monoclonal antibody, which has shown 
in vitro and in murine preclinical model to effectively block the PD-1/PD-L1 pathway 
and exhibit anti-tumor activity (for detailed results, please refer to the investigator's 
manual). 
Results from IBI308 Clinical Studies 
The Phase Ia dose escalation trial of IBI308 was initiated in September 2016, which 
was planned to enroll approximately 12-24 subjects with advanced solid tumors who 
had failed standard treatment. The dose escalation would follow the classic “3+3” 
design and 4 dose levels (1 mg/kg, 3 mg/kg, 200 mg and 10 mg/kg) would be evaluated. 
After completion of evaluation of the 1 mg/kg dose level, subjects would be randomized 
to either 3 mg/kg or 200 mg for independent evaluation. The dose-limiting toxicity 
(DLT) observation period was 28 days after the first dose in each dose level. After 
completion of DLT observation, the subjects are allowed to continue the subsequent 
IBI308 treatment (1 mg/kg, 3 mg/kg, and 10 mg/kg every 2 weeks or 200mg every 3 
weeks) until disease progression, intolerance, withdrawal of informed consent, or other 
reasons for discontinuation of the study (whichever occurs first). 
Pharmacokinetic evaluation of 1 mg/kg IBI308 was carried out in a multi-tumor subject 
(n=3). Preliminary results of single-dose administration showed that 1 mg/kg IBI308 
reached the maximum exposure of a single dose at the end of the infusion. After 
reaching the peak, the distribution was rapidly completed and elimination was slow 
(t1/2 was approximately 17.3d). It is a typical two compartment model of monoclonal

Innovent Biologics 
CIBI308B201 
22 
 
antibody, with a half-life similar to the physiological half-life of IgG4. 
Preliminary results of pharmacodynamic studies showed that IBI308 could rapidly (in 
24h) saturate the peripheral PD-1 receptor (95.8±2.3%) at a dose level of 1 mg/kg, and 
could maintain the occupancy of PD-1 receptor during the study phase of decreasing 
concentration (28d, C28d: 3.70 ± 0.15 μg/mL). Steady status is expected to be reached 
on Day 84 with continuous dose of 1 mg/kg Q2W (6 doses total). Provided no 
significant variation in drug clearance characteristics, the steady-state trough 
concentration is approximately 13μg/mL, which will sustainably maintain peripheral 
PD-1 receptor occupancy. 
Until February 8, 2017, three subjects each of the following dose levels, 1 mg/kg, 3 
mg/kg, and 200 mg, have completed DLT observation, with no DLT observed. 
Benefit/risk assessment 
Based on the mechanism of IBI308 and clinical safety profile of similar products, it is 
predicted that the major adverse events during clinical trial may be inflammations 
caused by activation of the immune system, including pneumonitis, colitis, hepatitis, 
renal dysfunction and inflammation of the endocrine system. According to the clinical 
data of the existing anti-PD-1 monoclonal antibodies, it is tolerated well despite of a 
relatively high incidence of adverse events, most of which will be alleviated after 
treatment. Only a small percentage of subjects have discontinued treatment due to 
severe adverse events. Since symptoms of immune related adverse events is atypical at 
early phase, researchers should pay close attention to early symptoms and signs, make 
timely judgments, adjust dose and give proper treatment per protocol section 5.4. 
Meanwhile, cautiously screen and exclude subjects with autoimmune diseases. 
In conclusion, the clinical pharmacology and safety data of IBI308 from Phase Ia 
clinical trial have demonstrated its pharmacological activity and safety in patients with 
advanced cancer. The efficacy of similar anti-PD-1 monoclonal antibody in cHL, 
supports the clinical trial of IBI308 in patients with relapsed or refractory cHL in China.

3 Study Design 
Study Plan 
This study is a multicenter, one-arm, phase II study to evaluate the efficacy and safety 
of IBI308 in relapsed or refractory classic Hodgkin's lymphoma. This study will enroll 
patients with relapsed or refractory cHL to receive intravenous (IV) IBI308 at 200 mg 
every three weeks (Q3W) for up to 24 months, or until disease progression, death, 
unacceptable adverse event(s), subject withdraws informed consent or other reasons 
specified in protocol. If the subject still has no disease progression after 24 months of 
IBI308 treatment and the investigator judges that the subject will still benefit from the 
study drug, the subject should sign additional informed consent to continue receiving 
free IBI308 treatment. . For subjects with first disease progression, if the clinical 
condition is stable, the investigator may let the subject continue to receive treatment 
until the total treatment time reaches 24 months or if disease progression, death, 
unacceptable adverse event(s), subject withdraws informed consent, or other reasons 
specified in protocol. 
The primary endpoint of the study is overall response rate (ORR), defined as the 
percentage of subjects with optimal response to partial and complete remission, 
evaluated according to the IWG 2007 criteria, and the Lugano 2014 criteria as an 
adjunct to the standard, both evaluated by IRRC. Analysis of primary endpoints will be 
performed after the last subject who meets the statistical and imaging assessment 
requirements and completes up to 24 weeks of follow-up. Subjects will have a safety 
follow-up 90 days after the last dose of IBI308. 
If the enrollment progressed slowly within the first 6 months after the start of the study 
(the number of subjects enrolled in the group within 6 months is less than 30), the 
sponsor may terminate the enrollment of the study early.

Study Rationales   
Rationales of Single Arm Study Design 
There is no high-quality evidence in three or more prior lines of systemic therapy to 
treat replaced/refactory cHL, and most evidence is monotherapy [5], including 
Brentuximab Vedotin 
[8], bendamustine 
[9], lenalidomide [10] and Vimos 
[11].  
Brentuximab Vedotin has not yet been listed in China. Bendamustine had an ORR of 
56% and a DOR of 5 months in 36 patients who had failed an average of four-line 
treatment [9]. The lenalidomide in the 38 patients who failed the average 4-line treatment 
had an ORR of 19% and a PFS of 4 months [10]. Of the 19 patients who failed the 
average 6-line treatment with everolimus, the ORR was 47% and the disease 
progression time was 7.2 months [11]. The sample size of the above studies is small and 
is not a recognized standard treatment. The ORR of Pembrolizumab and Nivolumab in 
patients with relapsed or refractory cHL who failed high-dose chemotherapy combined 
with autologous hematopoietic stem cell transplantation and Brentuximab Vedotin was 
72.5% (50/69) [18] and 66.3% (53/80) respectively[17]. The ORR of Pembrolizumab in 
patients who were not suitable to receive high-dose chemotherapy combined with 
autologous hematopoietic stem cell transplantation or Brentuximab Vedotin failed was 
65.4% (53/81) [18]. The above data indicate that anti-PD-1 monoclonal antibody alone 
has obvious curative effect on relapse or refractory cHL failure of multi-line treatment. 
Because of the lack of standard treatment in domestic third-line and above, this study 
chose a single-arm design. 
Rationales of Choosing 200 mg/kg Q3W 
This study is intended to be administered with 200 mg IBI308 Q3W. The choice of this 
mode of administration is based primarily on the ongoing Phase I (CIBI308A101) study 
of safety and exposure (concentration)-response (PD-1 receptor occupancy) 
relationship data, combined with preclinical in vitro/in vivo efficacy and other similar 
drugs’ data. 
The in vivo pharmacodynamic study of the SCID-Winn murine model and The MC38 
murine colon carcinoma model showed that the tumor suppressor ability of IBI308 
increased with dose escalation, and the 10 mg/kg IBI308 dose group significantly 
inhibited tumor growth. The equivalent dose in mankind was 0.8 Mg/kg. IBI308 can 
rapidly (24 hours ) saturate the peripheral PD-1 receptor (95.8±2.3%) at a dose of 
1mg/kg, and maintain peripheral PD-1 occupancy level during the period of IBI308

concentration continuously to decrease (28d, C28d: 3.70±0.15). The distribution of 
IBI308 in cynomolgus monkey’s different tissue showed that the IBI308 exposure of 
organs such as lung, liver, colon, small intestine, and lymph nodes was about 3.5-1/10 
of its in serum. Under the premise that the subject did not significantly change the drug 
clearance characteristics, IBI308 200 mg Q3W was expected to be administered to the 
steady state for 84 days (4 times), and the steady-state trough concentration was 
expected to be about 26 μg/mL. Under which IBI308 could continue to maintain 
peripheral and target organ PD-1 receptor occupancy. The above evidence supports the 
selection of IBI308 200 mg Q3W as a dosing regimen. 
Rationales of Primary Endpoint Analysis at Week 24 
One Study of the evaluations of Nivolumab monotherapy in a relapsed or refractory 
cHL patient study (Checkmate 205), of which one cohort enrolled patients failure from 
a high-dose chemotherapy combination with autologous stem cell transplantation and 
Brentuximab Vedotin. The results were published and the primary end point was ORR 
assessed by independent image review committee. The primary endpoint was analyzed 
at the time when all the 80 subjects were followed up for an average of 6 months. The 
ORR of the cohort was 65.3% (53/80), and the median time to first objective response 
was 2.1 months (IQR, 1.9-3.0 months). 31 cases had first objective response (58%, 
31/53) at 9.33 weeks (the first scheduled tumor evaluation time for the study was week 
9) [17]. In this study, the final analysis was performed at the time when the subject was 
followed up till maximum 24 weeks of treatment and at which the majority of objective 
mitigation events were expected to be observed. Because patients with response often 
have long-lasting duration of remission, and the reported median duration of response 
is 7.8 months in Checkmate205, subsequent assessments every 12 weeks can reduce 
unnecessary examinations for patients with remission [17]. 
Rationales of Choosing ORR as the Primary Endpoint 
In a study of 756 patients with relapsed/refractory cHL after failure of second-line 
standard therapy, the median progression-free survival was 1.3 years, with a median 
overall survival of 2.4 years [6].So for relapsed/refractory cHL, The Objective response 
rate is a common primary study end point in one-arm phase II study, as referring to the 
research design of the similar study (Brentuximab Vedotin [8], Nivolumab [17], 
Pembrolizumab [18]). We chose ORR as our study primary endpoint.

Rationales of Continuation of Treatment after Disease Progression 
Clinical data from listed products indicate that a small number of patients continue to 
receive immunotherapy may still receive clinical benefit despite prior evidence of 
disease progression (according to routine response criteria) before clinical objective 
response and/or disease stabilization [17, 21]. This phenomenon is currently explained 
with two reasons. First, increased inflammatory cells within the tumor may result in an 
increase in tumor volume, manifested as measurable lesion enlargement and the 
appearance of new, visible, immeasurable lesions. Over time, the malignant and 
inflammatory portions of the mass may shrink, resulting in significant imaging and 
clinical signs of improvement. Second, in some patients, the anti-tumor immune 
response is initiated slowly, and its early inhibition of tumors is less than tumor growth 
speed over time, anti-tumor activity will predominate and be manifested as an 
improvement in imaging response and clinical signs. In Checkmate 205, nine patients 
of the cHL who were re-administered after disease progressions, 6 of them were 
observed a further reduction in tumor burden [17]. Therefore, subjects treated with 
IBI308 will be allowed to continue to receive IBI308 if they are initially evaluated by 
IWG 2007 to have progressed disease, as the investigator confirm they will have 
clinical benefit and are tolerant to the study drug (see section 5.1.2). But they 
discontinue the study treatment after evidence of further progress.

5 Investigational Products 
Treatment Plan 
Treatment Administration 
The study drug, IBI308, will be administrated intravenously at 200 mg Q3W until 
maximum of 24 months, or until disease progression, death, intolerable toxicity, 
withdrawal of informed consent, or other reasons per the protocol. Other drugs in the 
study were non-study drugs. 
Continuation of Treatment after Disease Progression 
Subjects can continue to receive IBI308 after first disease progression, by IWG 2007, 
if they met all the following criteria: 
1. Patients may receive clinical benefits and their conditions will not worsen 
rapidly, if continue to receive the study treatment, as assessed by the investigator; 
2. Able to tolerate study drugs; 
3. The ECOG PS is stable; 
4. Does not delay the treatment of serious complications requiring urgent 
intervention (such as central nervous system metastasis); 
5. Subjects need to be fully informed before continuing to receive treatment with 
IBI308, and the investigator needs to clarify all foreseeable risks or discomforts and 
alternative treatment options. 
Subject to the above criteria, the decision to continue treatment after progression 
requires the investigator to discuss the decision with the sponsor's medical manager and 
record it in the study record. 
Subject data those who continue to receive IBI308 after initial disease progression are 
to be collected and data variables are to be collected as described in Table 1. 
If the patient continues to receive the study drug after confirmation, the radiographic 
evaluation will continue at the frequency per protocol. Treatment can be continued until 
the total treatment time reaches 24 months or recurrence of disease progression, death, 


IBI308

toxicity intolerance, withdrawal of informed consent or other reasons per protocol. 
Subjects who continue treatment with IBI308 after initial disease progression are to be 
recorded as “clinical deterioration” if they discontinue the treatment due to worsening 
of clinical symptoms without radiographic confirmed recurrence of disease progression.

The maximum interval between drug pauses is 6 weeks. If the status of IBI308 can be 
re-used within 6 weeks, the subject permanently discontinues IBI308 and enters the 
follow-up phase. Except for the following two situations: 
Due to the use of glucocorticoids in the treatment of immune related adverse events 
(irAE), the glucocorticoid reduction process caused IBI308 to be suspended for more 
than 6 weeks. In this case, you need to discuss with the sponsor's medical manager to 
decide if you can continue IBI308 treatment. The imaging examination to evaluate the 
efficacy is planned as planned and is not affected by the suspension of medication.

IBI308 has been suspended for more than 6 weeks due to treatment of AEs that may or 
may not be related to IBI308. In this case, you need to discuss with the sponsor's 
medical manager to decide if you can continue IBI308 treatment. The imaging 
examination to evaluate the efficacy is planned as planned and is not affected by the 
suspension of medication. 
Principles of Handling Immune Checkpoints Inhibitor Toxicity 
IBI308 works through activating T cells, which can cause autoimmune hyperfunction, 
leading to multiple systemic autoimmune diseases. In the clinical application of other 
immune checkpoint inhibitors, e.g. ipilimumab, nivolumab, pembrolizumab and 
atezolizumab, autoimmune-related AEs, such as pneumonia, diarrhea/colitis, renal 
insufficiency, rash, hepatitis, endocrine diseases and peripheral or central neuritis were 
observed. Once any of the above mentioned AEs is observed in this study, investigators 
are to monitor patients’ symptoms and signs, conduct necessary exams to judge the 
causality of the AE.  
If no alternative causes (such as disease progression, concomitant medications and 
infections) 
are 
found 
and 
treatment 
with 
glucocorticoids 
and/or 
other 
immunosuppressive agents is required (except for endocrine events such as 
hyperthyroidism/hypertropy, pituitary inflammation, type 1 diabetes, and adrenal 
insufficiency, immunosuppressive therapy may not be used, but it is still thought to be 
related to autoimmune hyperactivity caused by IBI308) , the above AE should be 
considered to be related to immune system hyperactivity caused by IBI308, diagnosed 
as irAE. 
Concomitant Treatment

inclusion/exclusion criteria to formally determine the eligibility of the subject. 
Patients who did not meet the relevant criteria for this study (screening failure) could 
be rescreened. If a rescreening of the patient is considered, the investigator must contact 
the sponsor's medical manager. When rescreening, the patient must re-sign the ICF and 
will be reassigned a subject number. 
Handling of Wrong Patient Enrolled 
The inclusion criteria must be strictly adhered to. If a participant who does not meet the 
entry criteria is found, the sponsor's medical manager and investigator will discuss 


IBI308 
Innovent Biologics 
CIBI308B201 
39 
 
whether to allow the subject to continue participating in the study, with or without the 
study drug. If the investigator believes that allowing the subject to continue 
participating in the study is appropriate for the subject from a medical perspective, and 
the sponsor's medical manager agrees with the investigator's decision, the subject may 
continue to participate in the study and accept study drug. If the investigator believes 
that the participant's continued participation in the study is medically appropriate, but 
the sponsor's medical manager disagrees with the investigator's decision, the subject 
may not continue to participate in the study (with or without study medication). The 
investigator was able to allow subjects who were accidentally enrolled in the study to 
continue to participate in the study only after receiving written approval from the 
sponsor.

Pathological Diagnosis 
The pathological slides used for pathological diagnosis in the research site during 
screening should be provided to the central pathological laboratory for pathological 
diagnosis confirmation. If the central pathological laboratory requires further 
pathological slides (white films) or wax blocks, the research site needs to provide. The 
patients with central pathological laboratory confirmed diagnosis can continue the 
treatment. Patients without central pathological laboratory confirmed diagnosis will be 
discontinued from the study if agreed by the research site. Diagnosis confirmation from 
central pathological laboratory will not affect the patient recruitment. 
Radiographic Assessment 
The baseline assessment should be performed within 28 days prior to the first study. 
The investigator can collect radiographic results from the 28 days prior to enrollment 
for evaluation. 
Tumor radiography uses enhanced CT (MRI, for subjects who are allergic to CT 
contrast agents) and PET. Enhanced CT examination will be done at baseline (baseline 
assessment will be performed within 28 days prior to enrollment), weeks 6/15/24 (±7 
days), every 12 weeks after 24 weeks (±14 days), and every 16 weeks after 48 weeks 
Week (±14 days). The examination site includes the neck, chest, abdomen, basin and 
other required anatomical sites until the start of new therapy, disease progression, 
withdrawal of ICF or death. The first disease progression needs to confirm after 4~6 
weeks. For patients who discontinue treatment for other reasons than disease 
progression confirmed by radiology, it is still necessary to carry out radiological 
evaluation according to the protocol, after treatment discontinuation, until the start of 
new therapy, disease progression, subject withdrawal of ICF or death. PET

examinations were performed at baseline, week 15 (±7 days), or early termination of 
study treatment.  
The tumor assessment was based on the IWG 2007 and the Lugano 2014 as an auxiliary 
evaluation criterion. IRRC is to be set in the study. Specific radiological assessment and 
sampling requirements can be found in the Radiology Sampling Guide.

Physical examination 
Complete physical examinations include: general condition, respiratory tract, 
cardiovascular, abdomen, skin, head and neck (including ears, eyes, nose, throat), 
lymph nodes, thyroid, musculoskeletal (including spine and limbs), genitals/anus, and 
nerves System evaluation. 
Refer to Table 1 for examination schedule.  
12-lead ECG 
The 12-lead ECG will be analyzed at the local laboratory according to Table 1. 
A 12-lead ECG examination will be performed after the subject rests for at least 5 
minutes in the supine position. All 12-lead ECGs should be recorded while the subject 
is resting in a supine position. Further ECG examinations will be performed when there 
is a clinical need, for example, in the event of a cardiac related adverse event. The 
examiner completes the ECG assessment on the same day and records the results on the 
ECG. The same assessment method should be used throughout the study. 
The investigator should evaluate all ECGs based on clinically significant 
abnormalities/no clinically significant abnormalities. If it is an abnormal result of 
clinical significance, the investigator should record the result as an AE in eCRF.

Vital signs 
Vital signs examinations will be performed as described in Table 1. Vital signs include 
body temperature, pulse rate, respiratory rate, and blood pressure. 
Investigators may perform additional vital sign assessment based on standard clinical 
practice or on a clinical basis. 
Additional vital sign record values (if applicable) can be collected on the eCRF when 
AE/SAE occurs. The date and time of acquisition and measurement will be recorded in 
the appropriate section of the eCRF. 
6.5.4.1 Pulse and blood pressure 
After the subject rests for at least 5 minutes, the subject's supine posture blood pressure 
and pulse are to be measured. Two or more readings should be taken, with an interval 
of 2 minutes between measurements, taking the mean. If the first two systolic pressure 
readings differ by more than 5 mmHg, they should be measured again and averaged. 
The date and time of acquisition and measurement will be recorded in the appropriate 
section of the eCRF. 
It is necessary to measure pulse and blood pressure before the study drug is 
administered. 
6.5.4.2 Body Temperature and Breathing 
On the planned dosing day, body temperature and breathing should be taken prior to 
drug administration. 
Weight and height 
Height was measured only during the screening period, and body weight was measured 
during the screening period and at the end of treatment. 
Pregnancy test 
Women with fertility potential (as defined in 4.3) are tested for pregnancy in urine or 
serum human chorionic gonadotropin (β-HCG) samples within 3 days prior to the first 
dose of study drug. If the urine β-HCG is positive or cannot be determined to be 
negative, a serum β-HCG sample pregnancy test is performed. If the result is positive, 
the subject is not eligible for admission/must stop participating in the study. A 
pregnancy is suspected during the study and should be reviewed.

• 
Thyroid function: T3, T4, TSH, FT3 and FT4. 
Pharmacokinetics 
Twelve subjects in selected research sites will be chosen for PK analysis. The total 
number of PK blood collection in the first cycle is 8: within 1 hour before the start of 
IBI308 infusion, immediately after infusion (+5min), 1h±5min after infusion, 
6h±15min after the start of infusion, 24h±1h. 48h±2h, 168h±8h (day 8), 336h±12h (day 
15); if the administration is delayed on the first day of the second cycle due to AE or 
other reasons, the first cycle needs to include an 504h±24h ( Day 22) sampling. From 
the second cycle, PK sample collection is performed every two cycles (the second, 
fourth, and sixth phase cycles, and so on). Except for the fourth cycle, the sampling 
time is: within 1 hour before the start of the infusion and immediately (+5min) after 
infusion, 1h ± 5min after infusion, 6h ± 15min, 24h ± 1h, 48h ± after the infusion, 168h 
± 8h (day 8), 336h ± 12h (day 15), 504h ± 24h (day 22, ie, within 1 hour before the fifth 
cycle of administration). 
2 ml of blood is to be collected using a procoagulant vacuum blood collection tube, 
serum is separated, and frozen for storage for PK analysis. Sampling methods, sample 
storage, transportation and analysis are detailed in the Laboratory Manual provided by 
the sponsor's designated central laboratory. 
The concentration of IBI308 in the serum is analyzed by ELISA and tested by the 
sponsor's designated central laboratory. All subjects are required to measure plasma 
concentrations at the blood collection points per the protocol.  
Pharmacodynamics 
Twelve subjects in selected research sites will be chosen for PD analysis. The total 
number of PD blood collection in the first cycle is 3: within 1 hour before the start of 
the IBI308 infusion, 24 h ± 1 h after the start of the infusion, and 168 h ± 8 h (Day 8). 
At the beginning of the second cycle, sample collection is performed every four cycles 
(the second, sixth, tenth, fourteenth, etc., and so on). 


IBI308

An anticoagulated vacuum blood collection tube will be used to collect 1 ml of blood 
for PD-1 receptor occupancy analysis. Sampling methods, sample storage, 
transportation and analysis are detailed in the Laboratory Manual provided by the 
sponsor's designated central laboratory. 
Immunogenicity 
The immunogenicity test will be performed during the first cycle, the second cycle, the 
fourth cycle, and every 4 cycles (the 8th, 12th, and 16th cycles, etc.) within 1 hour 
before the IBI308 infusion and during the safety follow-up. The analysis will be done 
at the central laboratory. 
Anti-drug antibody (ADA) titers will be tested in each subject, and ADA-positive serum 
samples will continue to be tested for neutralizing antibodies (NAb). 
4 ml of whole blood will be collected using a coagulation vacuum blood collection tube, 
serum is separated, and frozen for storage for ADA and NAb analysis. 
Sampling methods, sample storage, transportation and analysis are detailed in the 
Laboratory Manual provided by the sponsor's designated central laboratory. 
Quality of life assessment 
The quality of life assessment is conducted using the EQ-5D-5L and EORTC QLQ-C30 
scales, on the first day of dosing, each radiographic assessment, and the end of treatment 
follow-up. 
The EQ-5D-5L is a standardized tool for self-reporting health status indicators. Subjects 
will fill out 5 levels (no problem, mild, moderate, severe, and extreme) about their 
current health status, 5 dimensions (mobility, self-care, daily activities, pain/discomfort, 
and anxiety/depression) questionnaire. After synthesizing the levels of the five 
dimensions, the unique EQ-5D health status is defined. In addition, patients will be 
marked with a visual analog scale (VAS) ranging from 100 (the best imaginable health 
condition) to 0 (the worst health condition imaginable) to illustrate their current health 
status.  
EORTC's QLQ-C30 is a core scale for all cancer patients. It has 30 entries and can be 
divided into 15 dimensions, with 5 functional dimensions (body, role, cognition, mood 
and social function), 3 symptoms dimensions (fatigue, pain, nausea and vomiting), 1 
overall health/quality of life dimension, and 6 single items.

Biomarker analysis 
Subject to the ethics committee, all subjects who meet the inclusion criteria are required 
to provide archived tumor tissue at baseline or 4 unstained 4-5 micron sections prepared 
freshly during the screening period for PD-L1 testing. 
For the detection of mRNA expression levels of immune-related genes, subjects are 
required to provide archived tumor tissue at baseline or 4 unstained 4-5 micron sections 
prepared freshly during the screening period. 
Subjects are required to provide 10 ml blood samples at the following time points: the 
screening period, the treatment period, and the efficacy evaluation before the next 
treatment. The following tests may be performed: dynamic analysis of peripheral blood 
mononuclear cells in the enrolled patients by analysis of surface markers of different 
subtypes of lymphocytes and circulating tumor cells (e.g., PD-L1, Tim-3, CSF1R, 
TIGIT, LAG-3) , OX40, 4-1BB, GITR, CTLA-4, FOXP3, PD-1, PD-L2, CD4, CD3, 
TAM-related markers, MDSC-related markers, B2M, B7-H3, B7-H4, VISTA, etc.), 
predict the efficacy and prognosis of patients with anti-PD-1 immunotherapy. 
For a detailed description of sample handling, disposal, and shipping, refer to the 
Laboratory Manual. 
Storage and destruction of biological samples 
The sample will be disposed or destroyed and merged and anonymized. Additional 
analysis of the anonymized, combined samples may be performed to further evaluate 
and validate the analytical method. Any results obtained from these analyses may be 
reported separately from the CSR. 
The sample reproducibility analysis (if performed) will be performed in parallel with 
the bioanalysis of the test sample. These findings will not be reported in the clinical 
study report, but will be given separately in a bioanalytical report. 
7 Safety Reporting and Adverse Event Management 
Definition of adverse events 
An adverse event (AE) is defined as any untoward medical occurrence in a patient or 
clinical investigation subject administered a pharmaceutical product and which does 
not necessarily have to have a causal relationship with this treatment. All adverse events 
should be reported since the consent form is signed until 90th day after last 


IBI308 
Innovent Biologics 
CIBI308B201 
48 
 
administration of investigation products. AE includes but is not limited to the following 
situations:   
• 
Exacerbation of preexisting (before entering the clinical trial) medical 
condition/disease (including symptoms, signs, and abnormalities in laboratory 
tests) ; 
• 
Any new adverse medical conditions (including symptoms, signs, newly diagnosed 
diseases); 
• 
Abnormal laboratory test values or results which have clinical significance. 
Definition of serious adverse events 
A serious adverse event is any adverse event occurring at any dose or during any use of 
Sponsor's product that: 
• 
Results in death, except for deaths caused by the progression of clinical indications; 
• 
Is life-threatening (The definition of “life-threatening” is the subject is at risk of 
death when AE occurs, but does not include AEs that may cause death if the event 
is aggravated); 
• 
Requires inpatient hospitalization or prolongation of existing hospitalization, 
excluding the following: 
 
Rehabilitation institution 
 
Sanitarium 
 
Routine treatment in emergency room 
 
Day surgery (e.g. outpatient / day / ambulatory surgery) 
 
Hospitalization or prolongation of existing hospitalization that is not associated 
with AE aggravation. For example: The patient was hospitalized for clinical 
indication or preexisting indication, no new adverse events or no aggravation of 
preexisting indication (such as retest laboratory abnormalities that persisted); 
hospitalization for management reasons (such as annual routine Physical 
examination); hospitalization which specified in the protocol (e.g. as required 
by the protocol); elective hospitalization not associated with AE aggravation 
(e.g. elective surgery); scheduled treatment or surgery should be performed 
during clinical trial which recorded as baseline data; hospitalized for blood 
product use only. 
• 
Results in persistent or significant disability/incapacity; 
• 
Is a congenital anomaly/birth defect; 
• 
Is another important medical event. The definition of important medical events is 
AE that may not be immediately life-threatening or result in death or 


IBI308 
Innovent Biologics 
CIBI308B201 
49 
 
hospitalization but may jeopardize the patient or may require intervention to 
prevent one of the other outcomes listed in the definition above. 
AE severity assessment 
Investigator will evaluate the severity for all adverse events according to the NCI 
Common Terminology for Adverse Events (CTCAE), version 4.03. 
For adverse event terms not included in NCI CTCAE version 4.03, the severity will be 
evaluated according to the general guideline of NCI CTCAE: 
• 
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 
ageappropriate instrumental ADL (Instrumental ADL refer to 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 (Self care ADL refer to bathing, dressing and undressing, feeding self, 
using the toilet, taking medications, and not bedridde) 
• 
Grade 4 Life-threatening consequences; urgent intervention indicated. 
• 
Grade 5 Death related to AE. 
Causality assessment  
The relationship between Investigation products and AE can be judged by the following 
classifications and criteria: 
Table 3. Causality assessment 
Causality 
Criteria for Causality assessment 
definitely 
related 
The onset date of AE and administration of Investigation product is reasonable; 
The administration of Investigation products can explains the adverse event more 
reasonably than other causes (e.g. the subject's preexisting disease, environmental or 
toxic factors, or other treatments received by the subject); 
AE disappeared or reduction after drug withdrawal or dosage reducing; 
AE type is known for the suspected drug or its similar drugs  
AE reappear after re-medication. 
Possible

The onset date of AE and administration of Investigation product is reasonable; 
The administration of Investigation product can also reasonably explains the adverse 
event than other causes (e.g. the subject's preexisting disease, environmental or toxic 
factors, or other treatments received by the subject); 
AE disappeared or reduction after drug withdrawal or dosage reducing;

50 
 
Causality 
Criteria for Causality assessment 
Possible 
unrelated 
Another cause (e.g. the subject's preexisting disease, environmental or toxic factors, or 
other treatments received by the subject) can explains the adverse event more 
reasonably than Investigation products; 
AE still existed or no reduction after drug withdrawal or dosage reducing; 
AE dos not appear after re-medication.. 
Unrelated 
The onset date of AE and administration of Investigation product is unreasonable; or 
The adverse event has other apparent causes (eg, the subject's original disease, 
environmental or toxic factors, or other treatments the subject receives). 
Unable to 
judge 
The above information is not available, The Investigtor can’t assessment the causality 
according to the existing information and cannot get follow-up information. 
AE record 
Investigators should record AE or SAE using medical terminology/concept. Spoken and 
abbreviations should be avoided. All AEs (including SAE) should be recorded on the 
eCRF. 
AE collection period 
The investigator will collect AE via asking subject with non-inductive questions. 
All adverse events, including serious adverse events, will be collected since the consent 
form is signed until 90th day after last administration of investigation products, either 
observed by investigator or by the spontaneous reported by subjects. 
90 days after the last dose, the investigator should report serious adverse event 
associated with the study drug or procedure. 
Follow-up of AE 
Adverse events should be followed up until to baseline or grade 0~1 or the investigator 
believes that no further follow-up is required for reasonable reasons (if it cannot be 
recovered or has improved). If the adverse event cannot be recovered, a reasonable 
explanation should be recorded in the eCRF. Regardless of whether it is related to the 
study drug, the recovery condition and date of AE or SAE should be recorded in the 
subject’s eCRF and medical records. 
Contents of AE records 
Investigator should record adverse events completely, including diagnosis (if no 
diagnosis, record symptoms, signs including laboratory abnormalities), start date and 
end dates (if applicable), CTCAE severity grade and changes (level 3 or above), serious 


IBI308 
Innovent Biologics 
CIBI308B201 
51 
 
adverse event or not, adverse event of special interest or not, action taken for 
investigation products, the treatments for AE and the result of AE, and the relationship 
between adverse events and investigation product. 
For serious adverse events, the investigator should also record the date on which the 
AE meets the SAE criteria, the date the investigator was informed of the SAE, the 
criteria for the AE meets SAE, the date of hospitalization, the date of discharge, the 
cause of death, the date of death, autopsy or not, and causal assessment with clinical 
procedure, causal assessment with other drugs, and other possible causes of SAE. The 
investigator should also provide a basis of causality assessment and the narrative of 
SAE. In the SAE narrative, the subject's number, age, gender, height, weight; the 
indications for study drug and disease staging, and related general conditions; SAE 
occurrence, development, outcome and clinical course; laboratory findings related to 
SAE (the time, unit and normal range must be provided); previous history of SAE, 
combined disease and its occurrence and duration; SAE-related medication history, 
combined drug and the start date, duration, and dosage of the treatment; the start date, 
duration, and dosage of investigation products. 
The items related to the AE recording are described as follows: 
Diagnosis, symptoms and signs 
If a diagnosis has been made, the diagnosis should be recorded on the eCRF rather than 
individual symptoms and signs (e.g. recording liver failure, not jaundice, elevated 
transaminase, and flapping tremor). If the symptoms and signs are not sure be caused 
by the diagnosis at the time of reporting, they should recorded as separate AE/SAE. If 
it is sure that the symptoms and signs are caused by the diagnosis, only the diagnosis is 
reported separately, and the symptoms and signs are included in the diagnosis. The AE 
recording needs to delete symptoms and signs, and the SAE needs to send a follow-up 
update report. 
Adverse events secondary to other events 
Often, adverse events secondary to other events (e.g, caused by other events or clinical 
sequelae) should record their primary events unless the secondary event is severe or a 
serious adverse event. However, secondary events with significant clinical significance, 
if different from the time of occurrence of the primary event, should be recorded as 
independent adverse events in the eCRF. If the association between the events is not 
clear, it should be recorded separately in the eCRF. 


IBI308 
Innovent Biologics 
CIBI308B201 
52 
 
Persistent or recurrent adverse events 
A persistent adverse event is an adverse event that persists without a remission between 
the two evaluation time points. This adverse event should only be recorded once on the 
eCRF. The initial severity of the AE should be recorded and updated the severity when 
AE worsen. 
The AE of recurrence refers to an AE that has been alleviated between the two 
evaluation time points, but then occurred again. The reoccurred AE should be recorded 
separately in the eCRF. 
Abnormal laboratory test 
Clinically significant laboratory findings should be reported as AE. It is the 
responsibility of the investigator to review all laboratory abnormalities and to make 
medical judgments as to whether each laboratory should report an abnormality as an 
AE. 
Death 
All deaths that occurred during the entire trial period, including deaths occur during 90 
days after last administration of investigation products, whether or not related to the 
study drug, should be recorded in the death report form of the eCRF and reported to the 
sponsor timely. 
When a death event is recorded, the cause of death is recorded as an adverse event, and 
the result of the adverse event is death, and the death is reported as SAE; if the cause 
of death at the time of reporting is unknown, it should be recorded as “Death NOS” in 
eCRF and reported as a SAE. The exact cause of death should be further investigated. 
If death is clearly caused by tumor progression, it is not recorded and reported as an 
AE/SAE, but the investigator should record the death in the eCRF death report form 
and inform the sponsor timely. 
Preexisting Medical status 
Subjects' symptoms/signs during the screening period, only if there is a severity, 
frequency, or exacerbation of the disease (except for the worsening of the disease 
condition under study) should be recorded and reported as adverse events. Changes of 
preexisting medical status should be reflected in the record, such as "increased 
frequency of headache." 


IBI308 
Innovent Biologics 
CIBI308B201 
53 
 
Hospitalization, prolongation of existing hospitalization or surgery 
Any adverse events that result in hospitalization or prolongation of existing 
hospitalization should be recorded and reported as SAE, except following e: 
Prolonged hospitalization or hospitalization according to the trial design requirements 
(e.g. for drug delivery, efficacy evaluation, etc.) 
The subject was hospitalized for medical conditions that existed before participating 
clinical trial. For example, elective surgery/treatment scheduled before participating in 
the study. 
However, if the preexisting disease aggravated, the aggravated preexisting disease 
should be recorded as AE/SAE. 
Disease progression 
Disease progression is defined the subject’s condition worsen caused by the primary 
tumor which as the indication of investigation product. A new lesion relative to the 
primary tumor or progression of the original lesion is considered to be disease 
progression. Disease progression is not reported as an AE, The symptoms and signs 
Disease progression which result death, life-threatening, requiring hospitalization or 
prolonged hospital stay, leading to permanent or severe disability/capacity loss, leading 
to congenital anomalies/birth defects and other important medical events are not 
reported as SAE. 
Overdose 
The dosage over the dose specified in the protocol is the drug overdose. Overdose will 
be recorded in the eCRF. 
SAE and pregnancy reporting process 
SAE report: 
SAE will be reported since the consent form is signed until 90th day after last 
administration of investigation products. If SAE occurs, whether it is initial report or 
follow-up report, the investigator must immediately completed SAE form with 
signature. The SAE should be reported sponsor, regulatory authority and the ethics 
committee within 24 hours of the investigator awareness. The contact details are shown 
in the table below. 
If a SAE occurred outside the above-mentioned period, the SAE should also be reported

Subjects should return to site for evaluation as soon as possible after receiving an 
abnormal result (preferably within 48 hours). The assessment should include laboratory 
tests, detailed medical history and physical assessment, and should consider the 
possibility of liver tumors (primary or secondary). 
In addition to repeated testing for AST and ALT, laboratory tests should be performed 
including albumin, creatine kinase, total bilirubin, direct and indirect bilirubin, gamma-
glutamyltransferase, prothrombin time/international Standardized ratio, alkaline 
phosphatase. Detailed medical history collection should include: history of drinking, 
acetaminophen, soft drugs, various supplements, Chinese medicine, history of exposure 
to chemical drugs, family history, occupational exposure, history of sexual behavior, 
travel history, and history of contact with patients with jaundice, surgery, blood 
transfusion, history of liver disease or allergic disease, history of heart disease, history 
of immune disease, etc. Further examination may include detection of acute hepatitis 
A, B, C and E, liver imaging (eg, biliary tract), autoantibodies, and cardiac ultrasound.

CI (α will be adjusted for interim analysis）is larger than 40%, it is statistically 
confirmed that IBI308 monotherapy is efficacious in patients with relapsed or refractory 
cHL. 
Analysis populations 
The following analysis populations will be defined: 
Safety set (SS): patients who received at least one dose of study drug. 
Full analysis set (FAS): patients who received at least one dose of study drug and with 
measurable disease at baseline. Patients that are not confirmed by IRRC as cHL will 
not be included in FAS population. 
Per protocol set (PPS): subset of FAS, with no major protocol deviation that affects 
efficacy evaluation, no prohibited concomitant medication defined by protocol, and 
good compliance.

two-sided alpha as 0.05, a total sample size of 80 will provide 80% power to detect a 
16% difference for IBI308 monotherapy, that is, the ORR for IBI308 monotherapy 
reaches 56%. Considering a dropout rate as approximately 10%, the planned sample 
size is 90, to ensure at least 80 patients with available efficacy assessment (the EAS 
population).

9 Quality Assurance and Quality Control 
In accordance with the guidelines of the GCP, it is the responsibility of the sponsor to 


IBI308 
Innovent Biologics 
CIBI308B201 
63 
 
implement and maintain a quality assurance and quality control system in accordance 
with the appropriate standard operating procedures to ensure the implementation of 
clinical trials and the truthfulness of the data, and to collect, record and report 
compliance with the program, GCP and corresponding regulatory requirements.  
Clinical Audit 
The CRO authorized by the sponsor or sponsor will conduct a clinical audit of the study. 
The clinical monitor should conduct the audit according to the standard operating 
procedures of the sponsor or CRO and have the same rights and responsibilities as the 
sponsor's monitor. The auditor shall maintain regular communication with the 
investigator, the trial authorised personnel and the sponsor. 
Before the study begins, the auditor will assess the competency of each research center 
and report issues related to facilities, technical equipment, or medical staff to the 
sponsor. During the course of the study, the monitor will be responsible for monitoring 
whether the investigator has obtained written informed consent from all subjects and 
whether the data records are correct and complete. At the same time, the monitor will 
also compare the data input to the eCRF with the original data and inform the researcher 
of errors or omissions. The monitor will also control the compliance of the research 
center's program and test procedures, arrange for the supply of research drugs, and 
ensure that the drugs are kept in the proper conditions. 
The audit visit will be conducted in accordance with the requirements of relevant laws 
and regulations. From the time the subjects are enrolled, each center will receive regular 
monitoring visits. After each visit to the investigator, the auditor should submit a written 
report to the sponsor. 
Data Management / Coding 
This study will use an electronic data collection (EDC) system, and the research data 
will be entered into the eCRF by the investigator or authorized researcher. Researchers 
and authorized researchers will be properly trained and appropriate security measures 
will be taken for the equipment used, etc., prior to the start of the research center or data 
entry. 
Data entry for eCRF should be completed as soon as possible during or after the visit 
and updated at any time to ensure that it reflects the latest developments of the 
participants in the study. To avoid differences in outcome assessment by different 
evaluators, it is recommended that the same subject's baseline and all subsequent 


IBI308 
Innovent Biologics 
CIBI308B201 
64 
 
efficacy and safety assessments be performed by the same individual. Researchers are 
required to review the data to ensure the accuracy and correctness of all data entered 
into the eCRF. If some assessments are not made during the study, or if certain 
information is unavailable, not applicable, or unknown, the investigator should record 
it in the eCRF. The investigator should electronically sign the verified data. 
The CRA will review the eCRF and assess its completeness and consistency, and the 
CRA will compare the eCRF with the original documents to ensure consistency of key 
data. All data entry, corrections and modifications will be the responsibility of the 
investigator or his designee. The data in the eCRF is submitted to the data server and 
any changes to the data are recorded in the audit trail, ie the reason for the change, the 
name of the operator, the time and date of the modification will be recorded. The roles 
and authorities of the staff responsible for data entry in the research center will be 
predetermined. If there is any data challenge, the CRA or data management staff will 
issue a challenge in the EDC and the research center staff will be responsible for the 
Q&A. The EDC system will record the audit trail of the challenge, including the name, 
time and date of the investigator. 
Unless otherwise stated, eCRF will only be used as a form to collect data, not as a 
source. The original document is used by the investigator or hospital, relevant to the 
subject, and demonstrates the presence, inclusion criteria, and all records of 
participation in the study, including laboratory records, ECG results, and pharmacy 
drug delivery records. , subject folder, etc. 
The investigator is responsible for maintaining all original documents and for CRA to 
monitor them at each visit. In addition, regardless of the length of time the enrolled 
subjects participated in the study, the investigator must submit a complete eCRF for 
each enrolled subject. The program number and subject number of all supporting 
documents (such as laboratory records or hospital records) submitted with eCRF should 
be carefully verified, and all personal privacy information (including the subject's name) 
should be deleted or made illegible. To protect the privacy of the subject. The researcher 
verifies that the record has been reviewed by an electronic signature record and that the 
data of the record is accurate. The electronic signature will be completed using the 
researcher's user ID and password. The system will automatically attach the date and 
time of the signature. The researcher must not share the user ID and password with 
other people. If you need to change the data in the eCRF, you should follow the 
workflow defined by the EDC system. All changes and reasons for the changes will be 


IBI308 
Innovent Biologics 
CIBI308B201 
65 
 
recorded in the audit trail. 
Adverse events, concomitant diseases/history will be coded. The dictionary for coding 
will be described in the Clinical Research Summary Report (CSR). 
Quality Assurance Audit 
During the course of the study, the sponsor or the representative authorized by the 
sponsor may conduct quality assurance audits of the research center, research database 
and related research documents. At the same time, the corresponding regulatory agency 
may also inspect the research center, research database and related research documents 
at its own discretion. When the researcher receives the inspection notice from the 
regulatory body, he or she must immediately inform the sponsor. 
The quality assurance department of the sponsor conducts an audit of the clinical trial 
institution. The audit includes: the supply of the drug, the required test documents, the 
record of the informed consent process, and the consistency of the medical report form 
with the original documents. The content and scope of the audit can also be increased 
depending on the situation. After reasonable notice, the investigator shall allow the 
auditors commissioned by the sponsor to conduct inspections related to the trials and 
inspections conducted by the regulatory authorities. The primary purpose of an audit or 
inspection is to verify that the rights or health of the participants in the trial are protected, 
that the signing of the informed consent and the implementation of the trial process are 
carried out correctly, and that all data related to the study drug evaluation are processed 
and reported and pre-planned, The program, facility, ethical standard operating 
procedures, GCP and applicable regulatory requirements are consistent. Researchers 
should have direct access to all test files, original records, and raw data.
