Synopsis 
Section 2.2  Dose Expansion Phase (dose 
expansion) 
Added 10 patients to the planned 30 patients with 
refractory mCRC in Cohort B.  This patient 
population with mCRC reflects the current 
treatment practice in the US, in which TAS-102 and 
regorafenib are approved and used in the 3L+ 
setting.  Removed references to assessment times 
planned for Cohort B to reflect addition of other 
expansion cohorts that have different assessment 
times 
Section 1.4  Study Rationale 
Section 2.2.1  Primary Objective 
Section 2.2.2  Primary Endpoint 
Section 3.1  Description of the Study 
Section 3.1.2  Dose Expansion Phase 
Added Expansion Cohort C, which consists of 
approximately 40 patients with mCRC who have 
progressed on all standard therapies but who have 
not received prior TAS-102 and/or regorafenib 
(Cohort C). 
Enrollment of this cohort is based on the positive 
results of the phase 3 FRESCO trial conducted in 
China that led to approval of fruquintinib in that 
indication by the CFDA.  Cohort C represents a 
patient population in the US that is similar to that of 
the phase 3 FRESCO study.

approximately 
15 patients 
with 
advanced, 
refractory HR+/Her2- metastatic breast cancer 
(mBC), and expansion Cohort E, which consists of 
approximately 15 patients with triple-negative 
breast cancer (TNBC). 
Cohorts D and E were added based on data from 
phase 1 studies of fruquintinib conducted in China 
(2009-013-00CH1) and in the US (Protocol 2015-
013-00US1) 
suggesting

Dose Escalation 
Phase 
The primary objective of the dose escalation phase is to evaluate the 
safety and tolerability of fruquintinib in patients with advanced solid 
tumors and to determine the recommended Phase 2 dose (RP2D). 
The primary endpoint of the dose escalation phase is the incidence of 
DLT in each cohort.  DLT is defined as: 

Any Grade 4 non-hematologic toxicity;

Any Grade 3 non-hematologic toxicity related to study drug
except for nausea/vomiting, diarrhea, constipation, hypertension
and electrolyte imbalances downgraded within 3 days with
appropriate supportive treatment;

Grade 4 neutropenia lasting >3 days;

Grade 3 febrile neutropenia (absolute neutrophil count [ANC])
<1.0 × 109/L with a single temperature of >38.3°C or a sustained
temperature of ≥38°C for more than one hour;

Grade 4 thrombocytopenia or Grade 3 thrombocytopenia
associated with bleeding;

Protocol Number: 2015-013-00US1                                                        Version 4.0  
 Dose interruption for >14 days due to toxicity. 
The MTD is the highest dose at which no more than 1 of 6 patients 
developed a DLT.  If 2 or more patients developed DLT at a 
particular dose level, then that dose has exceeded the MTD. 
The safety and tolerability of fruquintinib will primarily be evaluated 
by the frequency and severity of AEs.  Other safety parameters 
include physical examination, vital signs, laboratory test results (ie, 
hematology, chemistry panel, thyroid function, and urinalysis), 12-
lead electrocardiogram, and echocardiogram. 
The secondary objectives of the dose escalation phase are: 
• 
To evaluate the PK characteristics of multiple-dose fruquintinib 
and to investigate the metabolite profile of fruquintinib in the 
plasma of patients with solid tumors.  
• 
To evaluate the anticancer activity of fruquintinib in patients with 
solid tumors according to RECIST Version 1.1.  
The secondary endpoints of the dose escalation phase are: 
• 
The primary PK parameters include: maximum plasma 
concentration (Cmax), time to reach maximum concentration 
(Tmax), terminal half-life (t1/2), area under the concentration-time 
curve in a selected time interval (AUC0-t), area under the 
concentration-time curve in the time interval from 0 to infinity 
(AUC0∞∞-∞), apparent clearance (CL/F), apparent volume of 
distribution (Vz/F) during the terminal phase according to 
CL/F/Ke, and the accumulation index based on AUC. 
• 
The objective response rate (ORR), disease control rate (DCR), 
duration of response (DoR), progression-free survival (PFS), 
overall survival (OS) and percentage change in tumor size from 
baseline according to RECIST v. 1.1. 
Study Objectives 
and Endpoints: 
Dose Expansion 
Phase 
The primary objective of the dose expansion phase is: 
To evaluate the anticancer activity of fruquintinib at the recommended 
Phase 2 dose (RP2D) from the dose escalation phase, in patients with 
advanced solid tumors. 
The primary endpoint of the dose expansion phase is: PFS rate. 
The secondary objectives of the dose expansion phase are: 
• 
To evaluate anticancer efficacy of fruquintinib, as assessed by 
ORR, DCR, DoR, PFS, and OS 
• 
To evaluate the pharmacokinetic (PK) characteristics of multiple 
dose fruquintinib and investigate the metabolite profile of 
fruquintinib in plasma.  
• 
To evaluate the safety of fruquintinib. 
The secondary endpoints of the dose expansion phase are:

Study Design 
This is an open-label study of fruquintinib comprised of a dose 
escalation phase in patients with advanced solid tumors of any type, and 
a dose expansion phase in patients with advanced solid tumors of any 
type (Cohort A), in patients with refractory mCRC (Cohorts B and C), or 
in patients with mBC (Cohorts D and E). 
Dose Escalation/ Phase： 
• 
Approximately 12 evaluable patients will be enrolled.  The 
actual number of patients enrolled will depend on the dose-
limiting toxicity (DLT) profile as well as maximum tolerated 
dose (MTD) level reached in this trial. 
• 
The dose levels to be investigated are 3 mg and 5 mg QD, 
3 weeks on/1week off. 
• 
Six DLT-evaluable patients will be enrolled in the dose 
escalation phase and will be treated with fruquintinib 3 mg QD 
(3 weeks on/1week off) orally.  If no more than 1 DLT occurs 
during the DLT observational window (ie, from Days 1-28 in 
Cycle 1) among the 6 patients, the trial will continue to enroll 
another 6 patients in the next dose cohort in which fruquintinib 5 
mg QD (3 weeks on/1week off) will be tested.  
• 
Safety monitoring and evaluation for the dose escalation phase 
will be carried out by the Safety Review Committee (SRC).   
• 
If no more than 1 patient at the dose level of 5 mg QD 
experiences a DLT, the dose escalation phase is completed and 
the expansion phase of the study will be conducted. 
• 
Upon completion of the dose escalation phase, the SRC will 
review aggregated safety and PK data and then select a 
fruquintinib dose as the recommended Phase 2 dose (RP2D) for 
the expansion phase of the trial.

• 
Blood samples for PK assay will be collected in Cycle 1 at the 
following time points: pre-dose (within 10 minutes), 1, 2, 4, 8, 
and 24 hours post dose on Days 1, 14 and 21. 
• 
Prior to confirmation of a DLT, if a patient received medical 
intervention or missed 4 or more fruquintinib doses during the 
DLT observational window, the patient will not be qualified as 
DLT-evaluable and will therefore be replaced. 
• 
If a patient does not meet the definition of DLT-evaluable 
patient during the DLT observation period, the patient will be 
replaced. 
• 
Patients who have completed the DLT observation period (Days 
1-28, Cycle 1) and are deemed to be benefiting from the 
fruquintinib treatment at the investigator’s discretion may 
continue the fruquintinib treatment until disease progression, 
death, intolerable toxicity, or at investigator’s discretion that the 
patient can no longer benefit from the study drug. 
• 
Tumor evaluations during the dose escalation phase are 
scheduled at screening and every 8 weeks (± 1 week) thereafter, 
ie, C3D1, C5D1, C7D1, etc (odd-numbered cycles).  Response 
assessments will be performed by the investigator using 
according to RECIST Version 1.1.  
• 
Patients will be followed until death or study completion. 
Dose Expansion Phase: 
Once the RP2D is determined, patients may enroll into one of the 
following cohorts and will receive fruquintinib at the RP2D: 
• 
Cohort A: Patients with advanced, refractory solid tumors of any 
type.  
• 
Cohort B: Patients with refractory mCRC who have progressed 
on all standard chemotherapies and relevant biologics and have 
also progressed on, or had intolerable toxicity with, at least 
1 FDA-approved third-line therapy (TAS-102 or regorafenib). 
• 
Cohort C:  Patients with refractory mCRC who have progressed 
on all standard chemotherapies and relevant biologics and have 
not received prior TAS-102 or regorafenib. 
• 
Cohort D:  Patients with hormone-receptor positive (ER+ 
and/or PR+)/Her2- metastatic breast cancer who have progressed 
on at least two line of prior systemic therapy. 
• 
Cohort E:  Patients with advanced triple negative breast cancer 
(TNBC) who have progressed on at least one cytotoxic therapy 
in the metastatic setting. 
The safety of all enrolled patients in the expansion cohorts will be closely 
monitored from the first day of fruquintinib dosing until 30 days after the

last dose.  All serious adverse events (SAEs) should be reported from the 
day the ICF is signed until 30 days after the last dose, regardless of 
relationship to study drug.  All adverse events (AEs) will be graded in 
accordance with the National Cancer Institute Common Terminology 
Criteria for Adverse Events (NCI CTCAE) version 4.03. 
Tumor response will be assessed according to RECIST Version 1.1 at 
screening and at study visits as defined in the Schedule of Events in 
Appendix A.  Confirmation of CR and PR is required at no less than 4-
week intervals between the date of initial response and the confirmation 
assessment date. 
Patients will be followed until death or study completion 
Study Treatment 
Dose Escalation Phase: 
Fruquintinib will be administered orally once daily (QD) 3 weeks 
on/1 week off for every 28-day treatment cycle until disease progression, 
death, intolerable toxicities, or at investigator’s discretion that the patient 
can no longer benefit from the study drug.  
Dose Expansion Phase: 
Fruquintinib will be administered orally QD 3 weeks on/1 week off for 
every 28-day treatment cycle until disease progression, death, intolerable 
toxicities, or at investigator’s discretion that the patient can no longer 
benefit from the study drug. 
End of Treatment 
(EOT) 
The criteria for the end of study treatment are as follows (if any of the 
following criteria is met): 
1. 
Disease progression (according to RECIST Version 1.1) unless 
there is reasonable evidence of clinical benefit to justify 
continuation on the study treatment.  The decision to continue 
treatment should be made by the investigator in consultation with 
the sponsor.  The disease progression date is the date when the 
radiological disease progression is first reported according to 
RECIST Version 1.1 criteria; 
2. 
Death; 
3. 
End of this study. 
Early discontinuation of study treatment will occur if any of the following

following Inclusion Criteria: 
1. 
Fully understand the study and voluntarily sign the informed 
consent form; 
2. 
≥18 years of age;  
3. 
Body weight ≥40 kg;  
4. 
Dose Escalation Phase: 
 
Histologically or cytologically documented, locally advanced or 
metastatic solid malignancy of any type (except squamous NSCLC) 
that has progressed on approved systemic therapy, and for whom no 
effective therapy or standard of care exists.  
Dose Expansion Phase:  
Cohort A:  Histologically or cytologically documented, locally 
advanced or metastatic solid malignancy of any type (except 
squamous NSCLC), that has progressed on approved systemic 
therapy, and for whom no effective therapy or standard of care exists. 
Cohort 
B: 
Histologically 
or 
cytologically 
documented 
adenocarcinoma of the colon or rectum that has progressed on, or had 
intolerable toxicity to, at least 1 FDA-approved third-line systemic 
therapy (TAS-102 or regorafenib).  Treatment failure is defined as: 
disease progression during or within 3 months after the last dose of 
standard therapy, or discontinuation of standard therapy because of 
unacceptable toxicity.  Patients must also have been previously 
treated with fluoropyrimidine-, oxaliplatin-, and irinotecan-based 
chemotherapy, an anti-VEGF biological therapy, and, if RAS wild 
type, an anti-EGFR therapy.  
Eligibility also requires knowledge of tumor RAS status (wild-type 
or mutant) as reported by investigators. 
Cohort 
C: 
Histologically 
or 
cytologically 
documented 
adenocarcinoma of the colon or rectum.  Patients must have 
progressed on, or had intolerable toxicity to, at least two prior 
regimens of standard chemotherapy, but must not have received prior 
TAS-102 or regorafenib.  Treatment failure is defined as: disease 
progression during or within 3 months after the last dose of standard 
therapy, or discontinuation of standard therapy because of 
unacceptable toxicity.  Prior therapy could have included adjuvant 
chemotherapy if a tumor had recurred within 6 months after the last 
administration of treatment.  Patients must have been previously 
treated with fluoropyrimidine-, oxaliplatin-, and irinotecan-based 
chemotherapy, an anti-VEGF biological therapy and, if RAS wild-
type, an anti-EGFR therapy. 
Eligibility also requires knowledge of tumor RAS status (wild-type 
or mutant) as reported by investigators.

triple negative breast cancer with ER-negative, PR-negative 
tumors as defined by local criteria.  
5. 
Hormone receptor positive mBC patients must have progressed on at 
least 2 lines of prior systemic therapy, including hormonal therapy or 
chemotherapy.  However, patients may not have received more than 
3 prior lines of cytotoxic chemotherapy in the metastatic setting. 
There is no limit to number of prior lines of hormonal therapy. 
6. 
Triple negative breast cancer patients must have progressed on at 
least 1 cytotoxic therapy in the metastatic setting, with the exception 
of subjects who progressed within 12 months of adjuvant therapy. 
However, patients may not have received more than 5 prior lines of 
cytotoxic chemotherapy in the metastatic setting. 
7.

of 0 or 1;  
9. 
Expected survival of more than 12 weeks;  
10. For female patients of childbearing potential and male patients with 
partners of childbearing potential, agreement to use a highly effective 
form(s) of contraception, that results in a low failure rate (<1% per 
year) when used consistently and correctly, starting during the 
screening period, continuing throughout the entire study period, and 
for 90 days after taking the last dose of study drug.  Such methods 
include: 
oral 
hormonal 
contraception 
(combined 
estrogen/ 
progestogen, or progestogen-only), associated with inhibition of 
ovulation together with a barrier method (eg, diaphragm, always 
containing a spermicide), intrauterine device (IUD), intrauterine 
hormone-releasing 
system 
(IUS), 
bilateral 
tubal 
ligation, 
vasectomized partner (on the understanding that this is the only one 
partner during the whole study duration), or sexual abstinence.  Oral 
contraception should always be combined with an additional 
contraceptive method (ie, barrier method) because of a potential 
interaction with the study drug.  The same rules are valid for male 
patients involved in this clinical trial if they have a partner of 
childbirth potential.  Male patients must always use a condom. 
A woman is considered to be of childbearing potential if she is 
postmenarcheal, has not reached a postmenopausal state (ie, ≥12 
continuous months of amenorrhea with no identified cause other than 
menopause), and has not undergone surgical sterilization (removal of

Statistical Analysis: 
By-subject listings will be created for variables from each CRF module, as applicable. 
Summary tables for continuous variables will contain at least the following statistics: number of 
patients (n), mean, standard deviation (SD), median, minimum, and maximum.  Summary 
tables for categorical variables will include n, and percentage. 
Safety Assessment 
All patients who have received at least one dose of fruquintinib will be 
included in the safety analysis set (SAS).  
All DLTs will be listed by dose cohort in DLT-evaluable patients for the 
dose escalation phase only. 
Safety will be evaluated based on the frequency and severity of AEs, 
change of laboratory test results, changes in vital signs, change in ECG, 
and change in echocardiogram.  Safety data will be listed and 
summarized by dose cohort, for patients overall, and for patients with 
mCRC (cohorts’ B and C) and mBC (cohorts’ D and E) who received 
fruquintinib at the RP2D. 
The severity of all AEs will be graded by the investigator according to the 
NCI CTCAE v4.03.  All AEs will be coded using the Medical Dictionary 
for Drug Regulatory Activities (MedDRA).  Treatment-emergent AEs 
(TEAEs) will be classified by MedDRA System Organ Class (SOC) and 
specified by Preferred Term (PT).  The incidence of TEAEs, SAEs, 
adverse events of special interest (AESIs), TEAEs leading to dose 
interruption, dose reduction, or study drug discontinuation will be 
summarized.   
For the laboratory assessments, such as hematology, serum biochemistry, 
urinalysis, and other urine parameters will be programmatically graded 
according to CTCAE severity grade.  Summary tables will be presented 
to show the number of patients by CTCAE severity grade with

corresponding percentages.  For parameters for which a CTCAE scale 
does not exist, the frequency of patients with values below, within, and 
above the normal ranges will be summarized.  Shift tables for selected 
hematology and serum biochemistry will also be presented showing 
change in CTCAE severity grade from baseline to worst grade post-
baseline. 
Pharmacokinetics 
All patients who received at least one dose of fruquintinib and have at 
least one plasma sample obtained and analyzed will be included in the 
Pharmacokinetic Analysis Set (PKAS).  
A non-compartmental model analysis will be performed for plasma 
concentration data by the central laboratory using WinNonlin (enterprise 
version).  The following summary statistics will be presented for 
concentration data and PK parameters, where appropriate: mean, standard 
deviation, coefficient of variation (CV%), median, minimum, maximum, 
geometric mean, and geometric mean CV%. 
Efficacy 
All patients from the safety analysis set who have at least one post-
baseline tumor assessment will be included in the efficacy analysis set 
(EAS).  
The ORR and DCR will be summarized by dose cohort with percentages 
and 95% exact confidence intervals for the EAS.  The PFS rate at 
specific time points (eg, PFS rate at 12 weeks for Cohort C) and its 95% 
confidence interval will be estimated using the Kaplan-Meier method. 
PFS, DoR, and OS will be summarized descriptively using Kaplan-Meier 
medians and quartiles for patients in the SAS.  Percentage change in 
tumor size will be determined for patients with measurable disease at 
baseline and will be derived at each visit by the percentage change in the 
sum of the diameters of target lesions (TLs) compared to baseline.  The 
best percentage change in tumor size will be summarized using descriptive 
statistics and presented using a waterfall plot.

BACKGROUND 
Angiogenesis is a prominent feature of many physiological and pathological processes, 
including wound healing, luteinization, and tumor growth [1,2].  It is regulated by a balance 
between local pro-angiogenic and anti-angiogenic factors.  Vascular endothelial growth 
factor (VEGF) is an important pro-angiogenic factor.  It is a key regulator of physiological 
angiogenesis during embryogenesis, skeletal growth, and reproductive functions.  It is 
also implicated in pathological angiogenesis such as that associated with tumor growth.  
In the normal state, endothelial cells divide approximately every 7 years, but in the 
malignant state, this growth rate is accelerated, and endothelial cells can divide as rapidly 
as every 7 to 10 days.  An “angiogenic switch” is necessary for tumors to obtain the 
necessary nutrients and oxygen to grow larger than a diameter of 1 mm. 
The biologic effects of VEGF are mediated through binding to 3 VEGF receptors, VEGFR-
1 (Flt-1), VEGFR-2 (KDR or Flk-1), and VEGFR-3.  Binding of VEGF to its receptors 
begins the signaling cascade that regulates cellular events involved in new blood vessel 
formation that produces a number of biologic effects including endothelial cell mitogenesis 
and migration, increased vascular permeability, and inhibition of endothelial cell apoptosis.  
Newly formed tumor vessels are markedly dependent on VEGF, and VEGF mRNA is 
upregulated in many tumors.  Tumor cells represent the major source of VEGF, but tumor-
associated stroma is also an important site of VEGF production[2,3]. 
Overexpression of VEGF has been associated with the promotion of tumor growth, 
elevation of the vascular permeability of tumor vessels, and poor prognosis in solid tumors, 
including colorectal carcinoma[4,5], gastric carcinoma[6,7], breast cancer[8,9] and lung 
cancer[10]. 
Fruquintinib is a small molecule tyrosine kinase inhibitor (TKI) with a novel chemical 
structure, which belongs to the quinazoline class.  It is a potent and highly selective 
VEGFR inhibitor discovered by Hutchison MediPharma Limited using rational drug 
design and high-throughput in vitro and in vivo biological screening of a large number of 
compounds

1.3 Clinical Experience 
The safety and efficacy of fruquintinib (HMPL-013) has been studied in a number of 
Phase 1, 2, and 3 studies in patients with a variety of solid tumors, including metastatic 
colorectal cancer (mCRC), and locally advanced, metastatic, or recurrent non˗small cell 
lung cancer (NSCLC) as a single agent or in combination with other anti-cancer therapies.  
Summary details can be found in the IB (Section 1.2)[11]. 
1.3.1 
Clinical Pharmacokinetics 
The PK of fruquintinib was evaluated in patients with advanced malignant solid tumors 
treated with a single-dose or multiple-dose regimen (Study 2009-013-00CH1).  
Following administration, a single oral dose of 1, 2, 4, 5 and 6 mg, fruquintinib showed a 
very low clearance.  The selection of the once daily (QD) dose regimen was justified by 
the terminal elimination t1/2 of >35 hours.  The AUC and Cmax generally increased dose-
proportionally at the dose levels from 1 mg to 6 mg.  Following multiple dosing, 
fruquintinib exposure reached steady state after QD administration for 14 days.  Based on 
the AUC for the QD dosing interval (24 hours), accumulation of fruquintinib exposure 
from the first dose to steady state was approximately 3-fold. 
The PK of a 4-week continuous dosing regimen of 5 mg QD was compared to a 3-week 
continuous dosing regimen of 6 mg QD followed by a 1-week break in fruquintinib therapy 
in patients with solid cancers (Study 2009-013-00CH1).  The PK results showed that 
fruquintinib PK profiles were similar for the 2 dosing regimens on the same dosing days 
(see Table 2).

Accumulation index R-AUC represented the ratio of AUC0-24h at the steady state/AUC0-24h on Day 1. If AUC0-

Two additional dosing regimens were compared: a 4-week continuous dosing regimen of 
4 mg QD, and a 3-week continuous dosing regimen of 5 mg QD followed by a 1-week 
break in fruquintinib therapy, were also evaluated in patients with advanced colorectal 
cancer (Study 2012-013-00CH3).  Overall, the PK profiles of fruquintinib obtained in this 
study were similar to those in the prior trial (Study 2009-013-00CH1). 
The effect of food intake on fruquintinib PK was investigated in healthy male adult 
volunteers at a single oral dose of 4 mg (Study 2012-013-00CH2).  The food effect was 
evaluated by assessment of the bioequivalence between the fasting condition (fasted) and 
the fed condition (food intake).  Fruquintinib exposure was represented by AUC0-∞ and 
Cmax.  The geometric mean ratios (90% confidence interval [CI]) of fasted/food intake 
met the bioequivalence criteria of 80%-125% for AUC and 70%-143% for Cmax.  
Absorption appeared to occur more slowly in the fed condition than in the fasting condition.  
1.3.2 
Clinical Safety  
Fruquintinib has not been approved in the United States, and clinical development is 
ongoing.  The expected events (identified risks) seen with fruquintinib treatment based 
on preclinical and clinical data and/or published data on compounds with similar 
mechanisms of action are summarized in Table 3.  The potential risks of fruquintinib are 
presented in Section 6.5.2 of the IB[11].

Clinical Efficacy 
The efficacy data in the Phase 1 study conducted in China (Study 2009-013-00CH1) 
showed encouraging clinical activity for fruquintinib.  A response was observed in the 
majority of heavily pre-treated patients with advanced cancers (see Table 5).  The results 
of two Phase 2 proof-of-concept (POC) studies provided evidence of clinical efficacy in 
patients with metastatic CRC (Study 2012-013-00CH1, third- or later lines therapy) and 
NSCLC (Study 2014-013-00CH1, third-line therapy) as compared with placebo.  The 
progression free survival (PFS) results established POC in both studies by meeting their 
respective primary efficacy endpoints.

[SD] recorded ≥ 8 weeks post randomization.  Duration of response was also assessed.  
Safety outcomes included TEAEs. 
The fruquintinib group had a significantly longer OS and PFS compared to the placebo 
group.  The median (95% CI) OS of the fruquintinib group was 9.30 (8.18, 1.45) months, 
while the median (95% CI) OS of the placebo group was 6.57 (5.88, 8.11) months 
(Figure 3).  The p-value of the stratified log-rank test was <0.001.  The stratified hazard 
ratio (HR [95% CI]) was 0.65 (0.51, 0.83).  The median PFS (95% CI) of the fruquintinib 
group was 3.71 (3.65, 4.63) months, while the median (95% CI) PFS of the placebo group 
was 1.84 (1.81. 1.84) months (Figure 4).

1.4 Study Rationale 
During the pathogenesis of cancer, tumors can secrete a variety of factors to stimulate the 
formation of tumor vasculature to increase their supply of nutrients and oxygen.  Such 
tumor vasculature is often formed by rapid endothelial cell proliferation and packed 
coarsely, leading to increased permeability and tumor cell leakage into the circulation.[1] 
Vascular endothelial cell growth factor (VEGF) and fibroblast cell growth factor (FGF) 
play key roles in tumor angiogenesis and have become two molecular targets of intense 
research for anti-angiogenesis therapies[2-3].  Highly selective antibodies against VEGF or 
its receptor VEGFR have demonstrated significant clinical benefit and have been widely 
used for the treatment of certain cancers[4].  Small molecule drugs, including sunitinib and 
sorafenib, targeting the VEGF receptor (VEGFR) tyrosine kinase signaling pathway have 
also contributed significantly in treating cancer[5,6].  However, most of the early 
generation small molecule VEGFR tyrosine kinase inhibitors (TKIs) inhibit many kinases 
other than VEGFR, resulting in “off-target” toxicities[7].  Therefore, improving kinase 
selectivity has become a key focus for newer generation TKIs.  
Fruquintinib, discovered by Hutchison MediPharma, demonstrated much improved kinase 
selectivity compared to sunitinib and sorafenib in the preclinical setting.  Fruquintinib 
selectively inhibits VEGFR, sparing many other kinases.  Preclinical safety evaluation 
results supported an acceptable safety profile for fruquintinib. 
The safety, tolerability, and pharmacokinetic properties of fruquintinib were assessed in a 
Phase 1 dose escalation study (Study 2009-013-00CH1) that was carried out in patients 
with advanced solid tumors in China.  Results indicated that fruquintinib was well 
tolerated up to 4 mg QD continuous therapy and 6 mg QD 3 weeks on/1 week off.  The 
maximum tolerated dose (MTD) has been reached in patients treated with the continuous 
regimen, but not in patients treated with the 3 weeks on/1 week off regimen.  The most 
frequently reported adverse events, including palmar-plantar erythrodysaesthesia (PPE), 

Date:  09 Jan 2020                                 Confidential                            41/144 
Protocol Number: 2015-013-00US1                                                        Version 4.0  
proteinuria, and hypertension.  The occurrence of aforementioned AEs and laboratory 
abnormalities are commonly reported in drugs of this class and can be managed effectively.  
Preliminary clinical efficacy was seen in patients with partial response (PR) and durable 
stable disease (SD).   
Although the MTD was not reached, the experience in China demonstrated that 
fruquintinib 5 mg (3 weeks on/1 week off) treatment had improved PFS in Chinese patients 
with metastatic CRC and NSCLC as compared with placebo and was well tolerated.  The 
extensive clinical trial experience in China is the rationale for investigating the 3 mg and 
5 mg regimens in the present Phase 1 study.  If there are clinically significant differences 
in the PK of fruquintinib in patients in the United States (US) compared to those of patients 
in China, the dose escalation sequence may need to be revisited. 
The rationale for adding approximately 40 patients with refractory mCRC in dose 
expansion Cohort B is provided by the results of the phase 3 FRESCO study completed in 
China (study 2013-013-00CH1 [FRESCO]).  FRESCO[14] was a randomized, placebo-
controlled, Phase 3 study of fruquintinib that demonstrated a significantly longer OS and 
PFS for fruquintinib compared to placebo in patients who had progressed on at least 2 lines 
of chemotherapy and relevant biologics and supported its approval by the CFDA.  
FRESCO showed an acceptable safety profile for fruquintinib that was consistent with 
other clinical trials.  For additional information about this trial, see Section 1.3.3 above, 
including Figure 3 and Figure 4.  This cohort will evaluate the safety and efficacy of 
fruquintinib in a patient population of mCRC that is reflective of treatment practice in the 
US where TAS-102 and regorafenib are approved and used in the third-line or greater 
setting. 
The rationale for adding expansion Cohort C of approximately 40 patients with mCRC who 
have progressed on all standard chemotherapy and relevant biologics but who have not 
received TAS-102 or regorafenib is also based on the positive results of the Phase 3 
FRESCO study completed in China (study 2013-013-00CH1 [FRESCO]).  This cohort 
will evaluate the safety and efficacy of fruquintinib in a patient population in the US that 
is similar to that of FRESCO. 
The rationale for adding Cohorts D (HR+/Her2-) and E (TNBC) of patients each with mBC 
is to evaluate the safety and efficacy of fruquintinib in patients with mBC based on data 
from Phase 1 studies of fruquintinib conducted in China (Protocol 2009-013-00CH1) and 
in the US (Protocol 2015-013-00US1), suggesting clinical activity in the proposed 
populations of mBC and based on data showing the clinical efficacy of anti-angiogenics in 
mBC.

STUDY OBJECTIVES AND ENDPOINTS 
2.1 Dose Escalation Phase 
2.1.1 
Primary Objective  
The primary objective of the dose escalation phase is to evaluate the safety and 
tolerability of fruquintinib in patients with advanced solid tumors and to determine the 
recommended Phase 2 dose (RP2D). 

Date:  09 Jan 2020                                 Confidential                            42/144 
Protocol Number: 2015-013-00US1                                                        Version 4.0  
2.1.2 
Primary Endpoint 
The primary endpoint of the dose escalation phase is the incidence of DLT in each cohort. 
 
DLT is defined as: 
 Any Grade 4 non-hematologic toxicity; 
 Any Grade 3 non-hematologic toxicity related to study drug except for 
nausea/vomiting, diarrhea, constipation, hypertension and electrolyte imbalances 
downgraded within 3 days with appropriate supportive treatment; 
 Grade 4 neutropenia lasting >3 days; 
 Grade 3 febrile neutropenia (absolute neutrophil count [ANC] <1.0 × 109/L with a 
single temperature of >38.3°C or a sustained temperature of ≥38°C for more than 
one hour);  
 Grade 4 thrombocytopenia or Grade 3 thrombocytopenia associated with bleeding; 
 Dose interruption for >14 days due to toxicity. 
The MTD is the highest dose at which no more than 1 of 6 patients developed DLT.  If 
2 or more of 6 patients developed DLT at a particular dose level, then that dose has 
exceeded the MTD. 
In general, the safety and tolerability of fruquintinib will be evaluated based on the AE 
data.  Other safety parameters include physical examination, vital signs, laboratory test 
results (ie, hematology, chemistry panel, thyroid function, and urinalysis), 12-lead 
electrocardiogram, and echocardiogram.

INVESTIGATIONAL PLAN 
3.1 
Description of the Study 
This is an open-label phase 1/1b study of fruquintinib comprised of a dose escalation phase that will 
enroll patients with advanced solid tumors of any type, and a dose expansion phase that will enroll 
patients with advanced solid tumors of any type (Cohort A), refractory mCRC (Cohorts B and C), or 
mBC (Cohorts D and E) (see study schema in Figure 5.) 
Figure 5 
 
Study Schema 
 
3.1.1 
Dose Escalation Phase   
• Approximately 12 evaluable patients will be enrolled.  The actual number of 
patients will depend on the occurrence of dose-limiting toxicities (DLTs) as well as 
the MTD level reached in this trial. 
• The dose levels to be investigated are 3 mg and 5 mg QD, 3 weeks on/1 week off. 
• Six DLT-evaluable patients will be enrolled in the phase and will be treated with 
fruquintinib 3 mg QD (3 weeks on/1 week off) orally.  If no more than 1 DLT 
occurs during the DLT observational window (ie, from Days 1-28 in Cycle 1) 
among the 6 patients, the trial will continue to enroll another 6 patients in the next 
dose cohort in which fruquintinib 5 mg QD (3 weeks on/1 week off) will be tested. 
• Safety monitoring and evaluation for the Dose Escalation phase will be carried out 
by the Safety Review Committee (SRC).  Additional information about the SRC 
is provided in Section 3.4. 

Date:  09 Jan 2020                                 Confidential                            45/144 
Protocol Number: 2015-013-00US1                                                        Version 4.0  
• If no more than 1 patient at the dose level of 5 mg QD experiences a DLT, the dose 
escalation phase is completed and the expansion phase of the study will be 
conducted. 
• Upon completion of the dose escalation/ phase, the SRC will review the aggregated 
safety and PK data and then select a fruquintinib dose as the RP2D for the 
expansion phase of the trial. 
• Blood samples for PK assay will be collected in Cycle 1 at the following time points: 
pre-dose (within 10 minutes), 1, 2, 4, 8, and 24 hours post dose on Days 1, 14 and 
21. 
• Prior to confirmation of a DLT, if a patient has received any prophylactic medical 
intervention or missed 4 or more fruquintinib doses during the DLT observational 
window, the patient is not DLT evaluable and will be replaced. 
• If a patient does not meet the definition of DLT evaluable patient criterion during 
the DLT observation period, the patient will be replaced. 
• Patients who have completed the DLT observation period (Days 1-28, Cycle 1) and 
are deemed to be benefiting from the fruquintinib treatment at the investigator’s 
discretion may continue the fruquintinib treatment until disease progression, death, 
intolerable toxicity, or at investigator’s discretion that the patient can no longer 
benefit from the study drug. 
• Please see Appendix A for the Schedule of Events and Section 5.2 for the dose 
modification instructions. 
• Patients will be followed until death or study completion. 
a. Dose-Limiting Toxicity Assessment Window 
The DLT assessment window will be 28 days in the first cycle (Days 1-28).  Any patient 
who is not considered evaluable for DLT as defined below will be replaced by an additional 
patient at that same dose level.  
NOTE:  Dose-limiting toxicity assessment does not apply to the expansion cohorts. 
b. Definition of DLT Evaluable Patients: 
A DLT evaluable patient has to meet the following criteria: 
• Has not received any prior anti-cancer therapy prior to DLT; AND 
• Has completed the first 28-day treatment cycle with complete safety evaluations 
and has received at least 85% of the assigned fruquintinib dose;  
OR

Protocol Number: 2015-013-00US1                                                        Version 4.0  
• Has a confirmed DLT during the first 28-day treatment cycle. 
c. Definition of a Dose-Limiting Toxicity 
 A DLT is defined as one of the toxicities defined for the primary endpoint of the 
dose escalation phase in Section 2.1.2.  These AEs occur during the DLT 
assessment window (Days 1-28, Cycle 1) and are determined by the investigator to 
have a reasonable possibility of being related to fruquintinib.   
 Any Grade 4 non-hematologic toxicity; 
 Any Grade 3 non-hematologic toxicity related to study drug except for 
nausea/vomiting, diarrhea, constipation, hypertension and electrolyte imbalances 
downgraded within 3 days with appropriate supportive treatment; 
 Grade 4 neutropenia lasting >3 days; 
 Grade 3 febrile neutropenia (absolute neutrophil count [ANC] <1.0 × 109/L with a 
single temperature of >38.3°C or a sustained temperature of ≥38°C for more than 
1 hour;  
 Grade 4 thrombocytopenia or Grade 3 thrombocytopenia associated with bleeding; 
 Dose interruption for >14 days due to toxicity; 
In the absence of clinical abnormality, repeat laboratory testing will be conducted to 
confirm significant laboratory findings prior to designation as a DLT. 
d. Definition of MTD 
The MTD is the highest dose at which no more than 1 of the 6 patients in each cohort of 
the dose escalation phase develops a DLT.  If 2 or more of 6 patients in each cohort of the 
dose escalation phase develop DLT at a particular dose level, that dose has exceeded the 
MTD.  
3.1.2 
Dose Expansion Phase 
The objectives of the dose expansion phase are to evaluate the anticancer activity and safety 
of fruquintinib at the RP2D determined at the end of the dose escalation phase, as described 
in Section 2.2. 
Once the RP2D is determined, patients may enroll into one of the following cohorts and 
will receive fruquintinib at the RP2D.   
• Cohort A: Patients with advanced, refractory solid tumors of any type 
• Cohort B: Patients with refractory mCRC who have progressed on all standard 
chemotherapies and relevant biologics and have also progressed on, or had 
intolerable toxicity with, at least 1 FDA-approved third-line therapy (TAS-102 or 
regorafenib).

• Cohort C: Patients with refractory mCRC who have progressed on all standard 
chemotherapies and relevant biologics and have not received prior TAS-102 or 
regorafenib. 
• Cohort D: Patients with hormone-receptor positive (ER+ and/or PR+)/Her2- 
metastatic breast cancer who have progressed on at least two line of prior systemic 
therapy. 
• Cohort E: Patients with advanced triple negative breast cancer (TNBC) who have 
progressed on at least one cytotoxic therapy in the metastatic setting. 
Detailed patient inclusion and exclusion criteria for each expansion cohort is described in 
Sections 4.1 and 4.2.  
The safety of all enrolled patients will be closely monitored from the first day of 
fruquintinib dosing until 30 days after the last dose.  All SAEs should be reported from 
the day the informed consent form (ICF) is signed through 30 days after last dose regardless 
of relationship to study drug.  All AEs will be graded in accordance with the NCI CTCAE 
v4.03.   
Tumor response will be assessed according to RECIST Version 1.1 at screening and at 
study visits according the Schedule of Events (Appendix A).  Confirmation of CR and PR 
is required at no less than 4-week intervals between the date of initial response and the 
confirmation assessment date. 
Patients will be followed until death or study completion (Appendix A). 
3.2 Sample Size 
Approximately 128 patients will be enrolled in this dose escalation/dose expansion study.  
Approximately 12 patients will be enrolled in the dose escalation phase, and approximately 
116 additional patients (6 with advanced solid tumors of any type, 40 with refractory 
mCRC who progressed on TAS-102 and/or regorafenib, 40 with mCRC who had not 
received TAS-102 or regorafenib, 15 with refractory HR+/HER2- mBC, and 15 with 
advanced, refractory TNBC) will be enrolled in the dose expansion phase. 
3.3 Investigational Site 
Approximately 12 sites will participate in the study. 
3.4 Safety Review Committee 
A Safety Review Committee (SRC) will be established under a charter to conduct safety 
data review and to determine the next step for dose escalation.  Safety monitoring and 
evaluation for dose escalation decisions will be carried out by the SRC upon completion 
of the of the DLT observation period of the last patient in each cohort.  The SRC is chaired 
by the Sponsor’s fruquintinib Clinical Program Leader; members will include the principal 
investigators (PIs), the Sponsor’s PK scientist, medical monitor, and the CRO’s medical 
monitor.  
Dose escalation decisions are based on AE and PK data from this ongoing trial, as well as 
consideration of safety and PK data at comparable drug exposure from patients in

previously conducted clinical trials in China. 
Regular safety data review will be conducted at pre-defined intervals and at the end of the 
DLT observation period (ie, first treatment cycle) of each dose cohort.  Safety and PK 
data from all enrolled patients will include laboratory test results, AEs, electrocardiogram 
(ECG) results, and PK data. 
3.5 Study Early Termination  
Hutchison MediPharma has the right to stop the study at any time.  The reasons for 
stopping the study may include, but are not limited to: 
• 
The incidence or severity of AEs in this or other studies indicates a potential health 
hazard to patients. 
• 
Patient enrollment is unsatisfactory. 
3.6 Patient Discontinuation 
All study participants have the right to withdraw from the study at any time.  The 
investigator has the right to discontinue a patient from the study for any medical condition 
that the investigator determines may jeopardize the patient’s safety if he or she continues 
in the study and for reasons of non-compliance (eg, missed doses, visits) or pregnancy or 
if the investigator determines it is in the best interest of the patient.  Any patient who 
discontinues treatment should be encouraged to return to the study site for a treatment 
completion visit.  See Appendix A for the assessments that are to be performed for 
patients who prematurely withdraw from the study during the treatment period.  The 
primary reason for discontinuation must be recorded on the appropriate Case report form 
(CRF). 
Study drug treatment will end if a patient meets any of the following 3 criteria:  
1. 
Disease progression (according to RECIST Version 1.1) unless there is reasonable 
evidence of clinical benefit to justify continuation on the study treatment.  The 
decision that the patient should continue treatment should be made by the 
investigator in consultation with the Sponsor.  The disease progression date is the 
date when radiological disease progression is first reported according to 
RECIST Version 1.1 criteria; 
2. 
Death; 
3. 
End of this study. 
Early discontinuation of study treatment will occur if any of the following criteria is 
met: 
1. 
Patient withdrawal of consent; 
2. 
Intolerable toxicity; 
3. 
Poor patient compliance; 
4. 
Use of other antitumor treatment during the study; 
5. 
Pregnancy occurred during the study treatment period; 
6. 
Patient is lost to follow-up;

refractory mCRC for whom approved therapy either does not exist or has proven to be 
ineffective or intolerable are eligible to participate in this study.  Patients will undergo a 
screening period of up to 4 weeks, during which they will be assessed for compliance with 
the inclusion and exclusion criteria as outlined below. 
4.1 
Inclusion Criteria 
To be eligible to participate in the study, patients must meet all of the following Inclusion 
Criteria:  
1. Fully understand the study and voluntarily sign the ICF;

metastatic solid malignancy of any type (except squamous NSCLC), that has 
progressed on approved systemic therapy, and for whom no effective therapy or 
standard of care exists. 
Cohort B: Histologically or cytologically documented adenocarcinoma of the colon 
or rectum that has progressed on, or had intolerable toxicity to, at least 1 FDA-
approved third-line systemic therapy (TAS-102 or regorafenib).  Treatment failure is

childbearing potential, agreement to use a highly effective form(s) of contraception, 
that results in a low failure rate (<1% per year) when used consistently and correctly, 
starting during the screening period, continuing throughout the entire study period, and 
for 90 days after taking the last dose of study drug.  Such methods include: oral 
hormonal contraception (combined estrogen/ progestogen, or progestogen-only), 
associated with inhibition of ovulation together with a barrier method (eg, diaphragm, 
always containing a spermicide); intrauterine device (IUD), intrauterine hormone-
releasing system (IUS), bilateral tubal ligation, vasectomized partner (on the 
understanding that this is the only one partner during the whole study duration), or 
sexual abstinence.  Oral contraception should always be combined with an additional 
contraceptive method (ie, barrier method) because of a potential interaction with the 
study drug.  The same rules are valid for male patients involved in this clinical trial

5.1.6 
Dose and Administration 
After the SRC review of Cohort 2, the RP2D was declared as 5 mg QD, 3 weeks on/1 
weeks off each 28-day cycle.  Patients from Cohort 1 who remain in the study may have 
their fruquintinib dose escalated to 5 mg QD at the discretion of the investigator and with 
the agreement of the Sponsor. 
If baseline (pre-dose) PK blood samples need to be collected on the days of PK sample 
collection, patients must take the investigational product after sampling at site.  
It is recommended that fruquintinib be taken with water (approximately 200 mL or 1 cup), 
1 hour before breakfast.  The administration time should be accurately recorded on the 
days of PK sampling. 
On the days of PK sampling, patients should avoid high-fat meals for the entire day and 
avoid consumption of any liquids other than water (up to 200 mL) within 1 hour before or 
after drug administration.  The patient is encouraged to avoid, or minimize the use of 
caffeine-containing foods or drinks, tobacco, tobacco products, and alcohol during the 
entire study.  If the patient cannot avoid taking any of the above listed substances during 
the study, it should be regarded as a habit and documented as demographic data. 
The following substances are prohibited during the study: grapefruit or grapefruit juice, 
illegal drug use, or excessive (> 1 drink/day) alcohol use. 
If patients miss a dose in the morning, a replacement dose can be taken before 6 pm on the 
same day.  Otherwise, the patient should not make up the missed dose, but should resume 
scheduled doses the next day per protocol.  The missed dose should be reported to the 
investigators and recorded in the CRF. 
5.2 Dose Modification 
5.2.1 
General Dose Adjustment Note 
The severity of AEs will be graded according to the NCI CTCAE v4.03.  Reasons for dose 
modifications or delays, the supportive measures taken, and the outcome will be 
documented in the patient’s chart and recorded in the CRF.

● Any toxicity that meets the definition of DLT during the DLT observation period will 
be considered as DLT for purposes of dose escalation and MTD determination. 
● For any concomitant conditions already apparent at baseline, the dose modifications 
will apply according to the corresponding shift in toxicity grade, if the investigator feels 
it is appropriate.  For example, if a patient has Grade 1 asthenia at baseline that 
increases to Grade 2 during treatment, this will be considered a shift of one grade and 
treated as Grade 1 toxicity for dose-modification purposes. 
● For toxicities that are considered by the investigator to be unlikely to develop into 
serious or life-threatening events, treatment will be continued at the same dose.  In 
addition, no dose reductions or interruptions will be required for anemia (non-
hemolytic) because it can be satisfactorily managed, unless serious (Grade ≥3) 
hemorrhage is present. 
● To recover from acute toxicity, unless otherwise indicated, the treatment can be 
interrupted for up to 14 days.  If a treatment delay longer than 14 days is required, the 
patient should be discontinued from the study drug.  Continuation/resumption of 
fruquintinib treatment after an interruption of more than 14 days must be discussed 
with the medical monitor or his or her designee. 
● Where several toxicities with different grades or severity occur at the same time, the 
dose modifications should be according to the highest grade observed. 
5.2.2 
Dose Modification Guidance 
5.2.2.1 Dose Modification Sequence by Starting Dose and for General Hematologic 
and Non-Hematologic Toxicity 
Dose reduction guidelines by starting dose and for haematologic and non-haematologic 
toxicities other than PPE, proteinuria, hypertension, decreased platelet count, hemorrhage, 
and liver function impairment are shown in Table 7 and Table 8.  In principle, treatment 
should be held until AE/toxicity resolves or improves to ≤Grade 1.  If a Grade 3 toxicity 
is expected to be manageable and reversible with a dose reduction, treatment should be 
held until toxicity resolves to ≤Grade 1.  Patients with Grade 3 non-haematologic toxicity 
that does not resolve to ≤Grade 1 within 2 weeks should permanently discontinue the study 
drug.  
Patients starting at 5 mg QD are allowed to have two dose reductions: one reduction from 
5 mg QD to 4 mg QD, and if not tolerated, then a second reduction from 4 mg QD to 3 mg 
QD.  Patients starting at 3 mg QD are allowed to have 1 dose reduction (ie, from 3 mg 
QD to 2 mg QD).  The lowest dose level permitted in the study is 2 mg (see Table 7).

5.3 Concomitant and Excluded Therapies 
5.3.1 
Concomitant Therapies 
Concomitant therapy includes any prescription medications or over-the-counter 
preparations used by a patient between the 7 days preceding the screening evaluation and 
the termination visit.  All concomitant medications should be reported to the investigator 
and recorded on the appropriate CRF. 
Patients who use hormonal therapy with GnRH agonists for prostate cancer, oral 
contraceptives, hormone-replacement therapy, or other allowed maintenance therapy 
should continue their use.  
Prophylactic use of anticoagulation for the maintenance of patency of permanent 
indwelling central venous access devices or for patients at high risk of venous 
thromboembolism is permitted during study treatment.  If patients are receiving anti-
coagulation, they should be very closely monitored for potential haemorrhage, and:

• 
Patients who are receiving warfarin or Coumadin-like products should have their INR 
monitored and maintained at the lower third of the therapeutic range (ie, 2.0-2.3), 
unless a higher INR is required for anti-thrombotic efficacy.  
• 
Patients who require low-molecular-weight heparin should receive the prophylactic 
dose and monitoring as specified by the appropriate product information label. 
The investigator should closely monitor patients receiving anti-platelet and/or anti-
thrombotic drugs with INR, aPTT and platelet count during study drug treatment and make 
a timely decision on whether to continue or stop such drugs in patients that report Grade ≥2 
haemorrhagic events at any site, based on an individual assessment of the risk-benefit 
balance (See Appendix J for additional information on the clinical management of severe 
or serious haemorrhagic AEs). 
Patients that develop arterial thromboembolic events should discontinue the study drug.  
If a patient suffers a venous thromboembolic event while still receiving study drug, it may 
still be possible for him or her to remain on study treatment under close monitoring and 
dose modification of study drug.  
All supportive measures consistent with optimal patient care will be given throughout the 
study. 
5.3.2 
Excluded Therapies 
Any therapy intended for the treatment of cancer (with the exceptions as noted above), 
whether currently marketed or experimental, is prohibited.  This includes, but is not 
limited to, the following: chemotherapy, hormonal therapy, biologic therapy, radiotherapy, 
or herbal therapy. 
Prophylactic antiemetic, granulocyte colony stimulating factors, granulocyte macrophage 
colony-stimulating factors, platelet simulating factors or erythropoietin are not allowed 
during the DLT observation period in the dose escalation phase. 
Concomitant use of acid-reducing agents (eg, proton pump inhibitors, histamine receptor 
antagonists, antacids) during the dose escalation phase should be avoided as those agents 
may interfere with identifying reliable MTD and/or RP2D. 
Concomitant use of medications that have a known risk of causing QT prolongation and/or 
torsade de pointes (see “combined” list at http://www.qtdrugs.org, with attention to those 
drugs listed as KR (“known risk”).  
Palliative radiation for symptom control is allowed provided it does not compromise tumor 
assessments of target lesions.  However, fruquintinib treatment should be suspended 
during the radiation period and not resumed until at least 7 days after radiation only after 
meeting the following criteria: 
 
Radiation related toxicities resolves to ≤Grade 2; 
 
No disease progression observed.

5.3.3 
Drug-Drug Interactions 
The potential of pharmacokinetic drug-drug interaction was tested in vitro.  Fruquintinib 
was not a substrate of efflux transporters.  Fruquintinib showed dose-dependent inhibition 
on P-gp and BCRP.  Based on the data for digoxin transport (mediated by P-gp) and 
estrone-3-sulfate transport (mediated by BCRP), the IC50 on P-gp and BCRP was estimated 
to be 4.60 and 1.29 µM, respectively. 
According to the present metabolism data, enzymes CYP3A4/5 play an important role in 
the metabolism of fruquintinib.  Fruquintinib had no marked inhibitory effects on CYPs 
1A2, 2B6, 2C8, 2C9, 2C19, 2D6, and 3A4/5 (IC50 >10 µM) and no induction of CYP1A2, 
 and CYP3A4 at the tested concentration of 10 µM.  No marked time-dependent 
inhibition was observed for CYPS 1A2, 2B6, 2C8, 2C9, 2C19, 2D6, and 3A4/5. 
Substrates of P-gp and BCRP, and inducers and inhibitors of CYP3A4/5 should not be 
administered concomitantly with fruquintinib, unless investigators consider it necessary.  
In this case, efficacy reduction and toxicity increases resulting from the interaction should 
be closely monitored.  Examples of the medicines to avoid are listed in Appendix F.

STUDY VISITS, ASSESSMENTS, AND METHODS 
6.1 Screening and Pre-treatment Assessments 
Written informed consent for participation in the study must be obtained before performing 
any study-specific screening tests or procedures.  Medical history and demographic 
information, including clinically significant diseases within the previous 5 years, oncology 
history (including cancer name, primary diagnosis date, stage of diagnosis, prior anti-
cancer therapies, and procedures) should be recorded in CRF.  Informed consent forms 
for patients who are not subsequently enrolled will be maintained at the study site.  All 
screening evaluations must be completed and reviewed by the investigator and the clinical 
monitor to confirm that patients meet all eligibility criteria before the first administration 
of fruquintinib. 
Please see the Study Flowchart provided in Appendix A for the schedule of screening and 
pre-treatment assessments.  Screening and pre-treatment tests will be performed within 
28 days of the first dose of study drug, unless otherwise specified.  Results of standard of 
care tests performed prior to obtaining informed consent and within 28 days prior to study 
entry may be used (except hematology, coagulation tests, clinical chemistry, or urinalysis 
results). 
6.2 Assessments During Treatment Phase 
All visits must occur within ± 3 days (± 1 day during cycle 1) from the scheduled date, 
unless otherwise noted (see Appendix A).  All assessments will be performed on the day 
of the specified visit unless a time window is specified.  Please see the Study Flowchart 
provided in Appendix A for the schedule of treatment period assessments. 
If scheduled study assessments cannot be obtained because of a holiday, assessments 
during Cycle 1 should be done either prior to or immediately after the schedule interruption, 
regardless of the proximity to the next scheduled visits.  If assessments cannot be obtained 
due to a holiday for any other cycle, these assessments should be obtained at the soonest 
following date, unless the soonest following date is within 7 days of other, regularly 
scheduled study assessments. 
If during the DLT assessment window, 2 or more patients in a single cohort experience the 
same study drug-related Grade 3 toxicity that does not otherwise qualify as a DLT, the 
patients subsequently enrolled to this dose level and to the subsequent dose level will 
undergo increased monitoring during Cycle 1, as clinically indicated.  Note: DLTs will 
not be collected during the Dose Expansion Phase. 
6.3 Safety Assessments  
6.3.1 
Vital Signs Assessment 
Vital signs will include measurements of body temperature, heart rate, respiratory rate, and 
systolic and diastolic blood pressure while the patient is in a seated position.  The patient 
should be seated for approximately 5 minutes before the measurement of the blood pressure.  
For patients with a baseline history of hypertension, or those who develop hypertension 
during the study, blood pressure should be monitored daily by the patient at home, at

3 hours (±2 hours) after the daily doses of anti-hypertensive medication, and the results 
recorded in a blood pressure diary.  Patients monitoring their blood pressure should bring 
their diary to each study visit. 
6.3.2 
Physical Examination 
A complete physical examination at screening should include the evaluation of head, eye, 
ear, nose, and throat; and cardiovascular, dermatological, musculoskeletal, respiratory, 
gastrointestinal, and neurological systems. 
At subsequent visits, a limited physical examination will be performed to assess changes 
from baseline abnormalities, any new abnormalities, and to evaluate patient-reported 
symptoms.  New or worsened abnormalities should be recorded as AEs if appropriate.  
In order to assess changes from baseline and screen for new abnormalities, the limited 
physical examination should assess for new or changed skin lesions, enlarged lymph nodes, 
and palpable masses.  Patient-reported symptoms should be directed to address the 
symptoms. 
Body height will be measured only at screening. 
6.3.3 
Laboratory Tests  
Samples for hematology, serum chemistry, urinalysis pregnancy, thyroid function, and 
specific tumor marker testing will be analyzed at the study site’s local laboratory.  
Laboratory assessments will include the following: 
Hematology (complete blood count [CBC], including red blood cell [RBC] count, 
hemoglobin, hematocrit, reticulocyte count, white blood cell [WBC] count with differential 
[neutrophils, eosinophils, lymphocytes, monocytes, basophils, and other cells], and platelet 
count; INR and aPTT); 
Serum chemistry (blood urea nitrogen [BUN], creatinine and creatinine clearance, sodium, 
potassium, chloride, bicarbonate, calcium, magnesium, phosphorus, glucose, triglycerides, 
total bilirubin, total cholesterol, ALT, AST, alkaline phosphatase (ALP), lactate 
dehydrogenase [LDH], uric acid, total protein and albumin); 
Serum pregnancy test at screening and at the Treatment Completion Visit for all women of 
childbearing potential, including those who have had a tubal ligation; 
Urine pregnancy test at each day 1 visit, starting at Cycle 2 Day 1, for all women of 
childbearing potential, including those who have had tubal ligation; 
Urinalysis (pH, glucose, protein, and blood); 
Thyroid function (thyroid stimulating hormone [TSH], free T3, and free T4); and 
Specific tumor markers (tumor markers to be collected will be addressed in Section 6.4) 
The normal value range of laboratory examination indicators at the study site’s local 
laboratory will be collected prior to the study.

are required to be performed as scheduled; ECG shall be performed pre-dose and at 3 hours 
(+ 15 minutes) post fruquintinib dose on Days 1 and 15 in Cycle 1.  ECG will be 
conducted on Day 1 of each cycle from Cycle 2 and onward.  QTcF interval should be 
calculated and be closely monitored.  See Appendix A.  MUGAs are permitted if 
echocardiograms cannot be performed. 
Test results will be reviewed by the investigator to determine patient eligibility at screening.  
Additional tests and other cardiac monitoring should be performed as clinically indicated 
during the study. 
6.4 Efficacy Assessments  
Tumor Assessment 
All measurable and evaluable lesions should be assessed and documented at screening and 
re-assessed at each subsequent tumor evaluation (see Appendix A).  Assessments should 
include computed tomography (CT) scans with oral or IV contrast (unless contraindicated) 
of the chest, abdomen, and pelvis.  MRI scans are allowed if CT contrast is 
contraindicated.  Other methods of assessment should be utilized as clinically indicated. 
Tumor assessments for dose escalation cohorts, Dose Expansion Cohort C, Dose 
Expansion Cohort D, and Dose Expansion Cohort E are scheduled at Screening and 
every 8 weeks (±1 week) thereafter, ie, C3D1, C5D1, C7D1, etc. (odd-numbered cycles).  
Tumor assessments for Dose Expansion Cohort A and Dose Expansion Cohort B are 
scheduled at Screening, C2D1, C3D1, C4D1, and every 8 weeks (±1 week) thereafter, ie, 
C6D1, C8D1, C10D1, etc. (even-numbered cycles). 
Subjects who permanently discontinue study drug for reasons other than progression of 
disease should continue to be followed for efficacy according to the schedule in 
Appendix A. 
All subjects are to have tumor assessments performed at the Treatment Completion visit, 
unless the subject was discontinued from treatment because of disease progression or the 
subject had tumor assessments performed within 14 days of the last dose of study drug. 
At the investigator’s discretion, CT scans may be repeated at any time if progressive 
disease is suspected. 
Disease status will be assessed using RECIST Version 1.1 (see Appendix C).  The same 
imaging procedure used to define measurable lesions at baseline must be used throughout 
the study for each patient. 
At the investigator’s discretion, other methods of assessment of measurable disease as per 
RECIST may be used.  Examples of other assessment methods include tumor markers, 
such as prostate-specific antigen (PSA) and cancer antigen 125 (CA-125) levels for patients 
with prostate and ovarian cancer, respectively.  However, tumor markers alone cannot be 
used to assess response.  If markers are initially above the upper normal limit, they must 
normalize for a patient to be considered in complete response. 
6.5 Study Completion/Early Termination Visit

with the use of an investigational medicinal product or other protocol-imposed intervention, 
whether or not considered related to the medicinal product. 
Adverse events will be assessed according to the NCI CTCAE v4.03. 
7.1.2 
Reporting of Dose Limiting Toxicity 
Investigators are required to report DLT events to the Sponsor within 48 hours of first 
awareness, during the dose escalation stage.  The communication must include an email 
that describes the event and indicates which DLT criterion was met (see Section 3.1.1 c, 
Definition of a Dose-Limiting Toxicity).  The Sponsor’s medical monitor must confirm 
that the event meets the DLT definition and communicate this back to the investigator by 
email.  A notification of each DLT event will be distributed by email to all investigators 
shortly after confirmation.  DLT events are again reviewed together with other safety data 
and PK data, at the SRC meeting upon completion of the DLT window of each dose cohort. 
NOTE:  Reporting of DLTs is not required during the dose expansion phase. 
7.1.3 
Serious Adverse Events and other AEs that require Expedited Reporting 
7.1.3.1 Serious Adverse Event Definition 
A serious adverse event (SAE) is any AE that has any of the following characteristics: 
• Fatal (ie, the AE actually causes or leads to death, except for deaths caused by the 
progress of disease) 
• Life threatening (ie, the AE, in the view of the investigator, places the patient at 
immediate risk of death) 
• Requires or prolongs inpatient hospitalization (excluding emergency or outpatient 
treatment) 
• Results in persistent or significant disability/incapacity (ie, the AE results in 
substantial disruption of the patient’s ability to conduct normal life functions) 

Date:  09 Jan 2020                                 Confidential                            70/144 
Protocol Number: 2015-013-00US1                                                        Version 4.0  
• A congenital anomaly/birth defect in a neonate/infant born to a female patient or 
female partner of a male patient exposed to the investigational product(s) 
• Considered as a significant medical event by the investigator (eg, may jeopardize 
the patient or may require medical/surgical intervention to prevent one of the 
outcomes listed above) 
• If an AE meets any of the above serious criteria, the AE should be reported to the 
sponsor as an SAE no more than 24 hours after awareness of the SAE. 
7.1.3.2 Potential Drug-Induced Liver Injury  
The investigator is required to discontinue study drug immediately and report all potential 
events of drug-induced liver injury (DILI), as defined below, regardless of whether it is a 
non-serious or serious AE to the sponsor no more than 24 hours after learning of the event.  
• Serum AST or ALT ≥3 × ULN together with total bilirubin ≥2 × ULN. 
This combination of lab abnormalities meets the biochemical criteria for Hy’s law, which 
is associated with a markedly increased possibility of severe DILI, and may progress to 
liver transplantation or death.  Some patients may present with symptoms such as: fatigue, 
nausea, vomiting, right upper quadrant pain or tenderness, fever, rash, and/or eosinophilia 
(>5%).  If Hy’s law is met, fruquintinib should be immediately discontinued, and patients 
need to be very closely monitored (bilirubin, ALP, AST, ALT measured 2-3 times weekly 
until the results return to baseline or normal), and other causes of liver injury evaluated (eg, 
new or worsening hepatobiliary metastases; non-malignant biliary obstruction; viral 
hepatitis A, B, or C; alcoholic or autoimmune hepatitis; preexisting or acute liver disease; 
ischemic liver injury; right-sided congestive heart failure; new or worsening liver 
metastases; or concomitant medication that could cause the observed injury).  
Consultation with a gastroenterologist or hepatologist should be considered. 
The findings described above must be reported to the sponsor no more than 24 hours after 
awareness of the event.  
7.1.3.3 Severe Hemorrhagic Events 
When a hemorrhagic event meets NCI CTCAE ≥ Grade 3 severity (regardless of whether 
it is serious or non-serious), the event should be reported to the sponsor no more than 
24 hours after first awareness of the event. 
The management of severe or serious hemorrhagic events will be conducted according to 
Appendix J. 
7.1.4 
Adverse Events Reporting Period 
After informed consent, but prior to initiation of study drug, all SAEs regardless of 
attribution will be collected. 
After initiation of study drug, all AEs and SAEs, regardless of attribution will be collected 
until 30 days following the last dose of study drug or a new treatment of anti-tumor therapy, 
whichever is earlier.  After this period, investigators should report only SAEs that are

Protocol Number: 2015-013-00US1                                                        Version 4.0  
considered to be related to the study drug. 
7.1.5 
Eliciting Adverse Events 
A consistent methodology of non-directive questioning for eliciting AEs at all patient 
evaluation time points should be adopted.  Examples of non-directive questions include: 
“How have you felt since your last clinic visit?” 
“Have you had any new or changed health problems since you were last here?”  
7.1.6 
Assessment of Severity  
Investigators will seek information on AEs and SAEs at each patient contact.  All AEs 
and SAEs, whether reported by the patient or noted by authorized study personnel, will be 
recorded in the patient’s medical record and on the appropriate AE/SAE form. 
For each AE and SAE recorded on the applicable CRF, the investigator will make an 
assessment of severity through clinical description by referring to the five-grade 
determination standard in the NCI CTCAE v4.03.  Please use the guideline below for the 
assessment of severity when the observed or reported AE is not listed in the NCI CTCAE 
v4.03: 
• 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 activities of daily living (ADL)*. 
• Grade 3: severe or medically significant but not immediately life-threatening; 
hospitalization or prolongation of hospitalization indicated; disabling; limiting self-
care ADL**. 
• Grade 4: life-threatening consequences; urgent intervention indicated. 
• Grade 5: death related to AE.

Protocol Number: 2015-013-00US1                                                        Version 4.0  
Activities of Daily Living 
*Instrumental ADL refer to preparing meals, shopping for groceries or clothes, using the 
telephone, managing money, etc. 
**Self-care ADL refer to bathing, dressing and undressing, feeding self, using the toilet, 
taking medications, and not bedridden. 
7.1.7 
Causality of Adverse Events 
The investigator will assess causal relationship between study drug and each AE.  
For SAEs, a causal relationship will also be assessed for concomitant medications, study 
procedures and additional study drug, etc.  A guideline to the interpretation of causality is 
provided in Appendix G. 
7.1.8 
Recording Adverse Events 
When an AE or SAE is recorded, the preferred medical terminology or concept should be 
used.  Abbreviations and colloquialisms (eg, jargon or slang) should be avoided.  All 
AEs (including SAEs) should be recorded in the CRF on the AE page. 
All AEs (including SAEs) would be recorded on the AE CRF, and the check box for 
“Serious” would be ticked for entries that fit the criteria for SAEs.  The investigator would 
also complete an SAE report and submit this to the sponsor or its designee within 24 hours 
of knowledge of the event.  
Only one medical concept should be recorded in the event field on the CRF. 
7.1.8.1 Diagnosis vs Symptoms and Signs 
If known, a diagnosis should be recorded on the CRF rather than individual signs and 
symptoms (eg, record only liver failure or hepatitis rather than jaundice, asterixis, and 
elevated transaminases).  However, if a constellation of signs and/or symptoms cannot be 
medically characterized as a single diagnosis or syndrome at the time of reporting, each 
individual event should be recorded as an AE or SAE on the CRF.  If a diagnosis is 
subsequently established, it should be reported as follow-up information. 
7.1.8.2 Adverse Event Occurring Secondary to Other Events 
In general, AEs occurring secondary to other events (eg, cascade events or clinical sequelae) 
should be identified by their primary cause with the exception of severe or serious 
secondary events.  For example, if severe diarrhea is known to have resulted in 
dehydration, it is sufficient to record only diarrhea as an AE or SAE on the CRF if the 
dehydration is mild.  
However, medically significant AEs occurring secondary to an initiating event that are 
separated in time should be recorded as independent events on the CRF.  For example, if 
a severe gastrointestinal hemorrhage leads to renal failure, both events should be recorded 
separately on the CRF. 

Date:  09 Jan 2020                                 Confidential                            73/144 
Protocol Number: 2015-013-00US1                                                        Version 4.0  
7.1.8.3 Persistent or Recurrent Adverse Events 
A persistent AE is one that extends continuously, without resolution between patient 
evaluation time points.  Such events should only be recorded once in the CRF.  The 
event’s initial severity should be recorded and updated when it increases so as to record to 
highest severity. 
A recurrent AE is one that occurs, resolves between patient evaluation time points, and 
subsequently recurs.  All recurrent AEs should be recorded on the CRF respectively. 
7.1.8.4 Abnormal Laboratory Values or Abnormal Vital Signs 
Not every laboratory abnormality/abnormal vital sign qualifies as an AE.  A laboratory 
test result/abnormal vital sign must be reported as an AE if it is a change from baseline and 
meets any of the following criteria:  
• Accompanied by clinical symptoms  
• Results in a change in study treatment (eg, dosage modification, treatment 
interruption, or treatment discontinuation)  
• Results in a medical intervention (eg, potassium supplementation for hypokalemia) 
or a change in concomitant therapy  
• Clinically significant in the investigator’s judgment  
It is the investigator’s responsibility to review all laboratory findings and abnormal vital 
signs.  Medical and scientific judgment should be exercised in deciding if an isolated 
laboratory abnormality should be classified as an adverse event. 
If the clinically significant laboratory abnormality is a sign of a disease or syndrome (eg, 
ALP and bilirubin 5 × ULN associated with cholecystitis), only the diagnosis (eg, 
cholecystitis) needs to be recorded on the CRF. 
If the clinically significant laboratory abnormality is not a sign of a disease or syndrome, 
the abnormality itself should be recorded as an AE or SAE on the CRF.  If the laboratory 
abnormality can be characterized by a precise clinical term, the clinical term should be 
recorded as the AE or SAE.  For example, an elevated serum potassium level of 
7.0 mmol/L should be recorded as “hyperkalemia.” 
Observations of the same clinically significant laboratory abnormality from visit to visit 
should not be repeatedly recorded as AEs or SAEs on the CRF, unless their severity, 
seriousness, or etiology changes.  
7.1.8.5 Death 
Deaths that occur during the protocol-specified AE reporting period that are attributed by 
the investigator solely to progression of disease should not be reported as AE/SAE.  All 
other on-study deaths, regardless of relationship to study drug, must be recorded on the AE 
CRF and immediately reported to the sponsor.  When a death is recorded, the underlying 
condition that caused or primarily contributed to the fatal outcome should be reported 
expeditiously as an SAE and death listed as the outcome of the event on the CRF.  If the 
primary cause of death is unknown and cannot be ascertained at the time of reporting, 

Date:  09 Jan 2020                                 Confidential                            74/144 
Protocol Number: 2015-013-00US1                                                        Version 4.0  
please record “Unknown cause of death” on the AE CRF, and “unexplained/unknown death” 
should be expeditiously reported as a SAE before further investigations into the specific 
cause of death.  If the death is attributed to progression of disease, it should not be 
recorded or reported as an AE/SAE but the investigator will record the death on the End of 
Treatment and End of Study CRFs as appropriate.  
7.1.8.6 Preexisting Medical Condition 
A preexisting medical condition is one that is present at screening.  Such conditions 
should be recorded on the CRF as medical history.  A preexisting medical condition 
should be recorded as an AE or SAE only if the frequency, severity, or character of the 
condition worsens during the study (excluding deterioration of the study disease 
conditions).  When such events are recorded on the CRF, it is important to convey the 
concept that the preexisting condition has changed by including applicable descriptors (eg, 
“more frequent headaches”). 
7.1.8.7 Hospitalization, Prolonged Hospitalization, or Surgery 
The investigator must document any AE that results in hospitalization or prolonged 
hospitalization unless the patient is hospitalized for 1 or more of the following reasons: 
• To undergo an efficacy measurement for the study 
• To undergo a diagnostic or elective surgical procedure for a preexisting medical 
condition that has not changed 
• To receive scheduled therapy for the target disease of the study 
In addition, hospitalization due solely to the progression of underlying advanced solid 
tumors should not be reported as a SAE. 
7.1.8.8 Pregnancy 
A female patient must be instructed to stop taking the study drug and immediately inform 
the investigator if she becomes pregnant during the study.  The investigator should report 
all pregnancies within 24 hours to the sponsor (the reporting period for pregnancy 
continues up to 30 days after completion of the study drug).  The investigator should 
counsel the patient and discuss the risks of continuing with the pregnancy and the possible 
effects on the fetus.  Monitoring of the patient should continue until conclusion of the 
pregnancy.  Pregnancies occurring up to 30 days after the completion of the study drug 
must also be reported to the investigator. 
Male patients must also be instructed to inform the investigator immediately if their partner 
becomes pregnant during the study or within 90 days after the last dose of study drug.  If 
such an event occurs, it should be reported as described above. 
Spontaneous abortion should always be classified as serious (as the sponsor considers these 
medically significant), recorded on the CRF, and expeditiously reported to sponsor. 
Any congenital anomaly/birth defect in a child born to a female patient or female partner 
of a male patient exposed to the investigational product should be recorded and reported as 
an SAE.

7.1.8.9 Worsening of Solid Tumor 
Worsening and/or progression of the patient’s solid tumor should not be recorded as an AE 
or SAE.  These data will be captured as efficacy assessment data only.  If there is any 
uncertainty about an AE being related only to the disease under study, it should be reported 
as an AE or SAE. 
7.2  Expedited Reporting Requirements 
Certain events require immediate reporting to allow the sponsor to take appropriate 
measures to address potential new risks in a clinical trial.  The investigator must report 
such events (both initial and follow-up) to the sponsor immediately; under no 
circumstances should reporting take place more than 24 hours after the investigator learns 
of the event.  The following is a list of events that the investigator must report to the 
sponsor within 24 hours after first learning of the event, regardless of relationship to study 
drug: 
• Serious adverse events (from informed consent to 30 days following the last dose 
of study drug or a new treatment of anti-tumor therapy) 
• Potential DILI events, regardless of seriousness 
• Severe hemorrhagic events (NCI CTCAE Grade ≥3), regardless of seriousness 
• Pregnancies 
• SAEs occurring beyond the above-mentioned time limit (30 days after the 
discontinuation of the study drug), if considered related to the study investigational 
drug, should also be reported to the sponsor.  
7.3 Duration of Follow-Up for Adverse Events  
The investigator will follow all unresolved AEs and SAEs until the events are resolved or 
stabilized, the patient is lost to follow-up, or it has been determined that the study treatment 
or participation is not the cause of the AE/SAE.  Resolution of AEs and SAEs (with dates) 
should be documented on the appropriate CRF and in the patient’s medical record to 
facilitate source data verification (SDV).  For SAEs, if, after follow-up, return to baseline 
status or stabilization cannot be established, an explanation should be recorded in the 
additional case details section of the CRF. 
For some SAEs, additional case details deemed necessary to evaluate the SAE report (eg, 
hospital discharge summary, consultant report, or autopsy report) appropriately may be 
followed-up by telephone, fax, email, and/or a monitoring visit to obtain. 
All pregnancies that occur during the study should be followed until pregnancy outcome.

STATISTICAL ANALYSIS  
All statistical analysis will be performed under the direction of Hutchison MediPharma 
personnel. 
The final analysis of study data will be based on all patient data up to the time when either 
all patients have discontinued the study or the study has been terminated.  Details of the 
statistical analysis and data reporting will be provided in the Statistical Analysis Plan (SAP) 
document finalized prior to database lock. 
Data will be summarized using descriptive statistics (continuous data) and/or contingency 
tables (categorical data) for demographic and baseline characteristics, efficacy 
measurements, safety measurements, and PK measurements.  Information regarding 
compliance with disease assessments and availability of data will be documented.  
Graphical techniques (eg, waterfall plots, Kaplan-Meier curves) will be used when such 
methods are appropriate and informative.  The baseline value used in each analysis will 
be the last (most recent) pre-treatment value.  Analyses will be based upon the observed 
data unless methods for handling missing data are specified.  Analyses will be performed 
using SAS® (Version 9.1 or higher). 
8.1 Analysis Populations 
The following analysis populations are defined for the study: 
• Safety Analysis Set (SAS): This population includes all patients who have received 
at least one dose of fruquintinib.  Safety data will be evaluated based on this 
population’s outcome.  Patients in the SAS will be analyzed by their actual dose 
initially received.  If patients have dose reduction during the study, all data will be 
summarized/analyzed based on the initial dose of study drug received.   
• Pharmacokinetic Analysis Set (PKAS): This population will include all patients 
who received at least one dose of fruquintinib and have at least 1 PK sample 
obtained and analyzed. 
• Efficacy Analysis Set (EAS): This population includes all patients who have 
received at least 1 dose of fruquintinib and have at least 1 post-baseline tumor 
assessment.  All efficacy endpoints will be analyzed based on this analysis set. 
8.2 Analysis of the Conduct of the Study 
A patient listing of all treated patients will be generated to describe site, patient number, 
screening date, first dosing date, duration of study treatment, analysis set in which the 
patient is included and disposition.  In the patient disposition listing, reason for study drug 
discontinuation will be included.  A table will be created to summarize these categories 
in terms of number and percent for each of the analysis set defined above. 
Patient demographics and baseline characteristics, such as age, sex, race/ethnicity, weight, 
type of malignancy, duration of malignancy, site of metastatic disease, and baseline ECOG 
performance status, will be listed and summarized.  All summaries will be presented 
overall, by dose level, and by tumor specific cohorts.

Major protocol deviations related to study inclusion or exclusion criteria, conduct of the 
trial, patient management, or patient assessment will be listed. 
Study drug administration data will be listed by dose level, and any dose modifications will 
be flagged.  Descriptive information will be provided regarding number of cycles, total 
duration of study drug exposure, actual duration of study drug taken, cumulative dose of 
study drug, dose intensity and relative dose intensity and the number and timing of 
prescribed dose reductions and interruptions.  
8.3 Safety Analysis 
Safety will be assessed through AEs, laboratory assessments, vital signs, and ECG results.  
Safety data will be listed and summarized by dose cohort across the 2 phases.  All DLT 
events will be listed by dose cohort for the dose escalation phase only. 
Severity of AEs will be graded by the investigator according to NCI CTCAE v4.03.  If a 
CTCAE criterion does not exist, the grade corresponding to the appropriate adjective will 
be used by the investigator to describe the maximum intensity of the adverse event: Grade 1 
(mild), Grade 2 (moderate), Grade 3 (severe), Grade 4 (life threatening), or Grade 5 (fatal) 
(see Section 7.1.6).  All AEs will be coded with Medical Dictionary for Drug Regulatory 
Activities (MedDRA).  
All AEs will be listed.  The focus of safety data summarization will be on treatment-
emergent adverse events (TEAEs), which are defined as AEs that occur or worsen in the 
period extending from the first dose of study drug to 30 days after the last dose of study 
drug in this study. 
TEAEs will be summarized as the number of patients and corresponding percentage by 
MedDRA System Organ Class (SOC) as well as Preferred Term (PT).  The incidence of 
TEAEs, SAEs, adverse events of special interest (AESIs), AEs leading to dose interruption, 
reduction, or treatment discontinuation will be presented by SOC and PT; by relationship 
to the investigational product and by toxicity grade for each dose level.  Changes in 
laboratory data will be summarized by severity grade using the NCI CTCAE v4.03.  
When abnormal laboratory results at the patient level are counted, the worst value during 
study treatment will be chosen.  
8.4 Pharmacokinetic Analysis 
Data of plasma concentration versus time are analyzed for PK parameters using the non-
compartmental model by WinNonlin enterprise version software.  The mean value, 
standard deviation, coefficient of variation (CV%), median value, minimum value, 
maximum value, geometric mean value and geometric mean CV% will be reported. 
Individual and mean plasma fruquintinib concentration versus time data will be tabulated 
and presented.  The individual and mean PK parameters based on the fruquintinib 
concentration versus time data, will include, but not be limited to total plasma exposure 
(AUC0-t and AUC0∞∞-∞), maximum plasma concentration (Cmax), apparent clearance 
(CL/F), and apparent volume of distribution (Vz/F).  The terminal half-life (t1/2) will also 
be estimated.  The actual times of plasma sample collection will be used for the PK 
analysis.

The methods for calculating pharmacokinetic parameters of fruquintinib: 
• Cmax: the maximum observed plasma concentration over the sampling period, taken 
directly from the data.  
• Tmax: time to reach Cmax, taken directly from the data.  
• The first-order rate constant associated with the negative slope of the terminal 
portion of the log-linear concentration-time curve.  A minimum of three points 
will be used. 
• Area under the plasma concentration versus time curve (AUC) to be determined by 
the trapezoidal rule (linear up/log down), where AUC0-t is the AUC from time zero 
until the last concentration point and AUC0∞∞-∞ is the AUC0-t + last concentration 
point divided by elimination rate constant (Ke). 
• Half-life (t1/2) to be determined according to t1/2 = 0.693/Ke where possible. 
• CL/F: apparent systemic clearance to be determined according to dose/AUC0∞∞-∞ 
• Vz/F: apparent volume of distribution, determined according to CL/F/Ke 
• Accumulation ratio: AUCDay14/AUCDay1 or AUCDay21/AUCDay1 
Where the concentration data are missing or listed as less than the lower limit of 
quantification, they will be regarded as zero (0) if occurring before Cmax.  After Cmax, zero 
points will not be included in calculations. 
Individual and mean fruquintinib concentrations will be plotted by dose level.  
Pharmacokinetic analysis of fruquintinib and its metabolites will be performed using the 
same technology. 
Venous blood samples for determination of concentrations of fruquintinib in plasma will 
be taken at the times presented in Appendix D.  If dose interruption occurs more than 
5 days (including 5 days) of PK sampling, the blood taking should be cancelled or at 
investigator’s discretion.  The date and time of collection of each sample and the date and 
time of dose will be recorded. 
8.5 Efficacy Analysis 
The efficacy endpoints include PFS, ORR, DCR, and OS.  Efficacy data will be listed and 
summarized by dose cohort and disease type. 
The ORR and DCR will be summarized with percentages and 95% exact confidence 
intervals.  The PFS rate at week 12 (Cohorts B and C) and week16 (Cohorts D and E) and 
its 95% confidence intervals will be estimated by the Kaplan-Meier method.  PFS, DoR, 
and OS will be summarized descriptively using Kaplan-Meier medians and quartiles.  
Percentage change in tumor size from baseline will be determined for patients with 
measurable disease at baseline and derived at each visit by the percentage change in the

sum of the diameters of target lesions (TLs) compared to baseline.  Best percentage 
change in tumor size will be summarized using descriptive statistics and presented using a 
waterfall plot. 
Objective Response Rate (ORR) 
The ORR is defined as the percentage of patients with at least one best overall response 
(BOR) of CR or PR according to RECIST Version 1.1.  To be assigned a status of PR or 
CR, changes in tumor measurements must be confirmed by repeat assessments performed 
no less than 4 weeks after the criteria for response are first met.  
The BOR in an individual patient according to the RECIST criteria is the best response 
recorded from the start of treatment until documented RECIST progression or the date of 
any further anticancer therapy, whichever comes first.  In the case of a patients without 
documented progression or additional anticancer therapy, BOR is determined using all 
available visit up until the last evaluable visit response. 
Disease Control Rate (DCR) 
Disease control rate is defined as the percentage of patients with a best overall response of 
CR, PR, or SD. 
Progression Free Survival (PFS) 
Progression free survival is defined as the time from date of first dose of study drug until 
the date of an objective disease progression as defined by RECIST v1.1 or death due to any 
cause. 
Patients who have not objectively progressed or died by the date of the analysis cut-off or 
received any further antitumor therapy will be censored at the time of the last evaluable 
objective tumor assessment before the cut-off date or the antitumor therapy start date. 
Progression-free survival rate is defined as the percentage of patients without evidence of 
progression or death at specific time points, such as week 12 (cohorts B and C), week 16 
(cohort D and E) on study.

Protocol Number: 2015-013-00US1                                                        Version 4.0  
Duration of Response (DoR) 
Duration of response is defined as the time from date of the first objective response, CR or 
PR, whichever comes first, until the occurrence of documented disease progression or 
death in the absence of disease progression.  If a patient does not progress following a 
response, then the DoR will be censored at the same time of PFS. 
Percentage Change in Tumor Size from Baseline 
Percentage change in tumor size will be determined for patients with measurable disease 
at baseline and is derived at each visit by the percentage change in the sum of the diameters 
of target lesions compared to baseline. 
Overall Survival (OS) 
Overall survival is defined as the time from the date of the first dose of study drug until the 
date of death (any cause).  Patients who did not die at the time of the statistical analysis 
will be censored at the time at which they were last known to be alive. 
8.6 Determination of Sample Size 
The total number of patients enrolled will depend on the number of dose escalations and 
the need to further characterize individual cohorts of single-agent fruquintinib administered 
at the RP2D. 
Dose Escalation Phase 
The sample size may vary depending on the number of dose levels evaluated and the 
number of DLTs observed in each cohort.  Patients who are considered not evaluable for 
DLT or PK will be replaced.  The sample size may increase when these patients are 
replaced. 
Dose Expansion Phase 
The primary objective of the dose expansion phase is to evaluate the anticancer activity of 
fruquintinib in patients with advanced solid tumors, treated at the RP2D from the dose 
escalation phase. 
Approximately 6 patients with advanced, refractory solid tumors of any type will be 
enrolled in Cohort A.  This sample size is not based on a formal statistical assumption. 
Additionally, enrollment in disease specific cohorts is planned as follows: 
• 40 patients in Cohort B (refractory mCRC with progression on TAS-102 and/or 
regorafenib)  
• 40 patients in Cohort C (refractory mCRC that has progressed on standard 
chemotherapies and relevant biologics but has NOT received TAS-102 or 
regorafenib)  
• 15 patients in Cohort D (HR+/Her2- mBC)  
• 15 patients in Cohort E [triple negative breast cancer (TNBC)]    
The number of patients in each cohort can provide adequate precision for the estimated 
incidence rates of patients having a specific AE, patients with CR/PR (ORR), patients with

ETHICS 
9.1 Independent Ethics Committee/Institutional Review Board (IEC/IRB) 
This protocol, protocol amendment(s), the ICFs, any information to be given to the patient, 
and relevant supporting information must be submitted by the PI to the IEC/IRB for review 
and approval before the study is initiated.  In addition, any patient recruitment materials 
must be approved by the IEC/IRB. 
The PI is responsible for providing written summaries of the status of the study to the 
Independent Ethics Committee/Institutional Review Board (IEC/IRB) annually or more 
frequently in accordance with the regulatory requirements and policies and procedures 
established by the IEC/IRB.  Investigators are also responsible for promptly informing 
the IEC/IRB of any protocol changes or amendments and of any unanticipated problems 
involving risk to human patients or others. 
In addition to the requirements to report protocol-defined AEs to the sponsor or its designee, 
investigators are required to report promptly to their respective IEC/IRB all unanticipated 
problems involving risk to human patients.  Some IECs/IRBs may want prompt 
notification of all SAEs, whereas others require notification only about events that are 
serious, considered related to study drug, and unexpected. 
9.2 Ethical Conduct of the Study 
The study will be conducted in accordance with the protocol, International Conference on 
Harmonization (ICH) guidelines, applicable regulations and guidelines governing clinical 
study conduct and the ethical principles that have their origin in the Declaration of Helsinki. 
9.3 Patient Informed Consent 
The investigator or his/her representative will explain the nature of the study to the patient 
and answer all questions regarding this study.  Before any study-related screening 
procedures are performed on the patient, the ICF will be reviewed, signed, and dated by 
the patient and the person who administered the informed consent.  A copy of the signed 
informed consent document will be given to the patient and the original will be placed in 
the patient's medical record and must be available for verification by study monitors at any 
time.  If applicable, the ICF will be provided in a certified translation of the local language. 
The ICF should be revised whenever there are changes to procedures outlined in the 
document or when new information becomes available that may affect the willingness of 
the patient to participate. 
For any updated or revised ICFs, the case history for each patient shall document the 
informed consent process and that written informed consent was obtained from the patient 
for the updated/revised ICF for his/her continued participation in the study.  The final 
revised IEC/IRB-approved ICF must be provided to Hutchison MediPharma for regulatory 
purposes. 
Signed and dated ICFs must remain in each patient’s study file and must be available for 
verification by study monitors at any time.

10 STUDY DOCUMENTATION, CASE REPORT FORM AND RECORDS 
10.1 
Source Data Verification 
Study monitors will perform ongoing source document verification to confirm that critical 
protocol data (ie, source data) entered into the CRFs by authorized site personnel are 
accurate, complete, and verifiable from source documents.  
Source documents include, but are not limited to, hospital records, clinical and office charts, 
laboratory notes, memoranda, patient diaries or evaluation checklists, pharmacy dispensing 
records, recorded data from automated instruments, copies of transcriptions that are 
certified after verification as being accurate and complete, microfiche, photographic 
negatives, microfilm or magnetic media, X-rays, patient files, and records kept at the 
pharmacy, laboratories, and medico-technical departments involved in a clinical trial. 
Source documents that are required to verify the validity and completeness of data entered 
into the CRFs must never be obliterated or destroyed. 
To facilitate source document verification, the investigator(s) and institution(s) must 
provide the sponsor direct access to applicable source documents and reports for trial-
related monitoring, sponsor audits, and IEC/IRB review.  The investigational site must 
also allow inspection by applicable regulatory authorities. 
10.2 
Use of Computerized System 
When clinical observations are entered directly into an investigational site’s computerized 
medical record system (i.e., in lieu of original hardcopy records), the electronic record can 
serve as the source document if the system has been validated in accordance with FDA 
requirements pertaining to computerized systems used in clinical research.  An acceptable 
computerized data collection system (for clinical research purposes) would be one that (1) 
allows data entry only by authorized individuals; (2) prevents the deletion or alteration of 
previously entered data and provides an audit trail for such data changes (eg, modification 
of file); (3) protects the database from tampering; and (4) ensures data preservation. 
If a site’s computerized medical record system is not adequately validated for the purposes 
of clinical research (as opposed to general clinical practice), applicable hardcopy source 
documents must be maintained to ensure that critical protocol data entered into the CRFs 
can be verified. 
10.3 
Retention of Records 
US FDA regulations (21 CFR §312.62[c]) and the ICH Guideline for Good Clinical 
Practice (GCP) require that records and documents pertaining to the conduct of this study 
and the distribution of investigational drug, including CRFs, consent forms, laboratory test 
results, and medication inventory records, must be retained by the Principal Investigator 
for 2 years after the last marketing application approval in an ICH region or after at least 2 
years have elapsed since formal discontinuation of clinical development of the 
investigational product.  All state and local laws for retention of records also apply.  No 
records should be disposed of without the written approval of Hutchison MediPharma.  
Written notification should be provided to Hutchison MediPharma for transfer of any 
records to another party or moving them to another location.

11 MONITORING 
It is understood that the responsible Hutchison MediPharma monitor (or designee) will 
contact and visit the investigator regularly and will be allowed, on request, to inspect the 
various records of the trial (CRFs and other pertinent data) provided that patient 
confidentiality is maintained in accord with local requirements. 
It will be the monitor’s responsibility to inspect the CRFs at regular intervals throughout 
the study and to verify the adherence to the protocol and the completeness, consistency, 
and accuracy of the data being entered on them.  The monitor should have access to 
laboratory test reports and other patient records needed to verify the entries on the CRF.  
The investigator (or deputy) agrees to cooperate with the monitor to ensure that any 
problems detected during these monitoring visits are resolved. 
12 DATA QUALITY 
The overall procedures for quality assurance of clinical study data are described in the 
sponsor or designee Standard Operational Procedures.  
Accurate and reliable data collection will be assured by verification and cross–check of the 
CRFs against the investigator’s records by the study monitor (source document 
verification], and the maintenance of a drug-dispensing log by the investigator.  
The sponsor or its agent will be responsible for data management of this study according 
to data management documents.  Any decision to use the CRF as a source document must 
be stated in the Data Validation Manual and the investigator must be advised of this 
decision.  A comprehensive validation check program will verify the data and discrepancy 
will be generated accordingly.  In the event of discrepant data, the sponsor or its agent 
will issue data queries to the site and request data clarification.  Site is required to respond 
to all queries and promptly enter date into the EDC system.  
The CRFs and correction documentation will be maintained in the EDC system’s audit trail.  
System backups for data stored by the sponsor and records retention for the study data will 
be consistent with the sponsor’s standard procedures.  
In order to facilitate analysis of the biological samples collected in this study, the treatment 
code will be released to the responsible analytical person when the samples have been 
received at the analytical site and are ready for assay.  The result of the analysis must not 
be released with individual identification of the patient until the database is closed. 
12.1 
Assignment of Preferred Terms and Original Terminology  
For classification purposes, preferred terms will be assigned to the original terms entered 
in the CRF, using the most up to date version of MedDRA for AEs and diseases and World 
Health Organization (WHO) drug terms and procedures dictionary for treatments and 
surgical and medical procedures.

Note: 
1． A written informed consent form should be obtained prior to any protocol-specific procedure or test.  Tests completed within 28 
days prior to enrollment can be used for screening and do not need to be repeated (except hematology, coagulation test, clinical 
chemistry, or urinalysis results). 
2． Unless otherwise indicated, the visit window during the treatment period will be ± 3 days (± 1 day during cycle 1). 
3． Patients who complete or prematurely discontinue the study need to return to the study site for a follow-up at 30 (±7) days after 
the decision to discontinue treatment permanently.  Ongoing AEs will be followed until the event has resolved to baseline grade, 
the event is assessed as stable by the investigator, new anti-tumor treatment is initiated, the patient is lost to follow-up, the patient 
withdraws consent, or when it has been determined that the study treatment or participation is not the cause of the AE. 
4． The treatment completion visit tumor assessment can be omitted if treatment ended because of disease progression or the patient 
had a tumor assessment within 14 days prior to the last dose of study drug. 
5． Concomitant medication includes any prescribed or over-the-counter medicines.  All medication used by patients within 7 days 
before screening and 30 days after study treatment completion should be recorded.  At each visit, all medication used since the 
prior visit should be recorded.

6． Vital signs include blood pressure, heart rate, respiratory rate, and temperature.  For patient with a baseline history of 
antihypertensive medications, blood pressure should be monitored at 3 hours (±2 hours) after the daily doses of anti-hypertensive 
medication. 
7． Please refer to Section 6.3.2 for the assessments that should be completed as part of the Complete and Limited Physical Exams. 
8． Hematology consists of complete blood count, including red blood cell count, hemoglobin, hematocrit, reticulocyte count, white 
blood cell count with differential (neutrophils, bands, lymphocytes, eosinophils, monocytes, basophils, and other cells), and platelet 
count. 
9． The chemistry panel includes blood urea nitrogen, creatinine and creatinine clearance, sodium, potassium, chlorine, bicarbonate, 
calcium, magnesium, phosphorus, glucose, alanine aminotransferase, bilirubin (total), aspartate aminotransferase, alkaline 
phosphatase, lactate dehydrogenase, total cholesterol, triglycerides, uric acid, protein (total) and albumin. 
10． Urinalysis includes pH, glucose, protein, and blood.  A 24-hour urine should be collected from all patients with >1+ proteinuria 
for quantitative test of urine protein during the screening.  If protein ≥2+ during the period of study treatment, a 24-hour urine 
test should be conducted within 1 week. 
11． MUGAs are permitted if echocardiograms cannot be performed. 
12． Includes free T3, free T4, and thyroid-stimulating hormone (TSH). 
13． Women of childbearing potential will receive a serum pregnancy test during screening and within 30 days after treatment 
completion, and a urine pregnancy test on Day 1 of each 28-day cycle beginning at Cycle 2.  If pregnancy is suspected, additional 
tests should be completed.  In the case of menopausal women, the date of menopause onset should be recorded. 
14． CA125 level for patients with ovarian cancer, PSA for patients with prostate cancer, or other tumor markers (as appropriate) should 
be obtained as clinically indicated or with each tumor assessment. 
15． On Days 1 and 15 in Cycle 1, ECG should be performed at pre-dose and at 3 hours (± 15 minutes) post-dose (around Cmax after 
single dose and at steady state in order to evaluate concentration-QT relationship for fruquintinib).  Untimed ECG will be 
conducted on Day 1 of each cycle from Cycle 2 and onward. 
16． After informed consent, all SAEs and concomitant medications will be collected.  After initiation of study drug, all AEs and 
SAEs will be collected until 30 days following the last dose of study drug or a new treatment of anti-tumor therapy, whichever is 
earlier.  After this period, investigators should report only SAEs that are considered to be related to the study drug.

17． For subjects in Expansion Cohorts B, C, D, and E - Survival follow-up (by telephone) should be performed every 12 (±2) weeks 
from the date of the Treatment Completion visit.  All subsequent anti-tumor therapy and information about ongoing or unresolved 
study drug-related SAEs will be collected.  For the patients that discontinue the study without PD, all available tumor assessment 
results during survival follow-up will be recorded in the CRF until confirmation of PD.  The date and cause of death should be 
recorded, if applicable.  Patients who withdraw consent are encouraged to be followed for survival.  If the patient has clearly 
expressed his/her refusal to be followed after withdrawal of consent, he/she will terminate the study and no survival follow-up will 
be performed.

Appendix C  Response Evaluation Criteria in Solid Tumors Version 1.1 
(RECIST Version 1.1) 
Quick Reference: 
http://ctep.cancer.gov/guidelines/recist.html 
 
Patient Eligibility  
Only patients with measurable disease at baseline should be included in protocols where 
objective tumor response is the primary endpoint.  Measurable disease is defined as 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.  
Methods 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.  CT is the best 
currently available and reproducible method to measure lesions selected for response 
assessment.  MRI is also acceptable in certain situations (eg, for body scans but not 
for lung). 
• Lesions on a chest X-ray may be considered measurable lesions if they are clearly 
defined and surrounded by aerated lung.  However, CT is preferable. 
• Clinical lesions will only be considered measurable when they are superficial and 
≥10 mm in diameter, as assessed using calipers.  For the case of skin lesions, 
documentation by color photography, including a ruler to estimate the size of the lesion, 
is recommended. 
• Ultrasound (US) should not be used to measure tumor lesions.  
• Tumor markers alone cannot be used to assess response.  If markers are initially above 
the upper normal limit, they must normalize for a patient to be considered in complete 
response.  
• Cytology and histology can be used in rare cases (eg, for evaluation of residual masses 
to differentiate between Partial Response and Complete Response or evaluation of new 
or enlarging effusions to differentiate between Progressive Disease and 
Response/Stable Disease).  
• Use of endoscopy and laparoscopy is not advised.  However, they can be used to 
confirm complete pathological response.  
Baseline Disease Assessment  
All baseline evaluations should be performed as closely as possible to the beginning of 
treatment and never more than 4 weeks before the beginning of the treatment.

Measurable 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; when CT scans have 
slice thickness >5 mm, the minimum size should be twice the slice thickness).  
• 10 mm caliper measurement by clinical exam (lesions that cannot be accurately 
measured with calipers should be recorded as non- 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 is recommended to be no greater than 5 mm).  At baseline and in follow-up, 
only the short axis will be measured and followed.  
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 measurable if the soft tissue component meets the definition of measurability 
described above.  
“Cystic lesions” thought to represent cystic metastases can be considered measurable if 
they meet the definition of measurability described above.  However, if non-cystic lesions 
are present in the same patient, these are preferred for selection as target lesions.  
Non-measurable Lesions  
Non-measurable lesions are all other lesions, including small lesions (longest diameter 
<10 mm or pathological lymph nodes with 10 to <15 mm short axis), as well as truly non-
measurable lesions.  Lesions considered truly non-measurable include: leptomeningeal 
disease, ascites, pleural or pericardial effusion, inflammatory breast disease, lymphangitic 
involvement of skin or lung, abdominal masses/abdominal organomegaly identified by 
physical exam that is not measurable by reproducible imaging techniques.  Blastic bone 
lesions are non-measurable. 
Lesions with prior local treatment, such as those situated in a previously irradiated area or 
in an area treated with other loco-regional therapy, are usually not considered measurable 
unless there has been demonstrated progression in the lesion.  Study protocols should 
detail the conditions under which such lesions would be considered measurable.  
Target Lesions  
• All measurable lesions up to a maximum of two lesions per organ and five lesions in 
total, representative of all involved organs, should be identified as target lesions and 
recorded and measured at baseline.  
• Target lesions should be selected on the basis of their size (lesions with the longest 
diameter) and be representative of all involved organs, as well as their suitability for 
reproducible repeated measurements.  
• All measurements should be recorded in metric notation using calipers if clinically 
assessed.

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 diameters, which will be 
used as reference to further characterize any objective tumor regression in the measurable 
dimension of the disease.  If lymph nodes are to be included in the sum, only the short 
axis will contribute.  
Non-target Lesions  
All lesions (or sites of disease) not identified as target lesions, including pathological lymph 
nodes and all non-measurable lesions, should be identified as non-target lesions and be 
recorded at baseline.  Measurements of these lesions are not required and they should be 
followed as “present,” “absent,” or in rare cases, “unequivocal progression.” 
Evaluation of Target Lesions  
Complete Response (CR): Disappearance of all target lesions.  Any pathological lymph 
nodes (whether target or non-target) must have reduction in short axis to <10 mm.  
Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions, 
taking as reference the baseline sum of diameters.  
Progressive Disease (PD): At least a 20% increase in the sum of diameters of target lesions, 
taking as reference the smallest sum on study (this may include the baseline sum).  The 
sum must also demonstrate an absolute increase of at least 5 mm.  
Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase 
to qualify for PD.  
Special Notes on the Assessment of Target Lesions  
Lymph nodes identified, as target lesions should always have the actual short axis 
measurement recorded even if the nodes regress to below 10 mm on study.  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.  
Target lesions that become “too small to measure”: While on study, all lesions (nodal and 
non-nodal) recorded at baseline should have their actual measurements recorded at each 
subsequent evaluation, even when very small.  However, sometimes lesions or lymph 
nodes become so faint on a CT scan that the radiologist may not feel comfortable assigning 
an exact measure and may report them as being “too small to measure”, in which case a 
default value of 5 mm should be assigned. 
Lesions that split or coalesce on 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”.

Evaluation of Non-Target Lesions  
Complete Response (CR): Disappearance of all non-target lesions and normalization of 
tumor marker levels.  All lymph nodes must be non-pathological in size (<10 mm short 
axis).  
Non-CR / Non-PD: Persistence of one or more non-target lesion(s) and/or maintenance of 
tumor marker levels above normal limits.  
Progressive Disease (PD): Unequivocal progression of existing non-target lesions.  When 
patient has measurable disease, to achieve “unequivocal progression‟ on the basis of the 
non-target disease, there must be an overall level of substantial worsening in non-target 
disease such that, even in presence of SD or PR in target disease, the overall tumor burden 
has increased sufficiently to merit discontinuation of therapy.  A modest “increase” in the 
size of one or more non-target lesions is usually not sufficient to qualify for unequivocal 
progression status. 
When patient has only non-measurable disease:  There is no measurable disease 
assessment to factor into the interpretation of an increase in non-measurable disease burden.  
Because worsening in non-target disease cannot be easily quantified, a useful test that can 
be applied is to consider if the increase in overall disease burden based on change in non- 
measurable disease is comparable in magnitude to the increase that would be required to 
declare PD for measurable disease.  Examples include an increase in a pleural effusion 
from “trace” to “large” or an increase in lymphangitic disease from localized to widespread. 
New Lesions  
The appearance of new malignant lesions denotes disease progression:  
• The finding of a new lesion should be unequivocal (ie, not attributable to differences 
in scanning technique, change in imaging modality or findings thought to represent 
something other than tumor, especially when the patient’s baseline lesions show 
partial or complete response).  
• If a new lesion is equivocal, for example because of its small size, continued therapy 
and follow-up evaluation will clarify if it represents truly new disease. If repeat scans 
confirm there is definitely a new lesion, then progression should be declared using the 
date of the initial scan.  
• A lesion identified on a follow-up study in an anatomical location that was not 
scanned at baseline is considered a new lesion and disease progression.  
It is sometimes reasonable to incorporate the use of 18F-fluorodeoxyglucose positron 
emission tomography (FDG-PET) scanning to complement CT in assessment of 
progression (particularly possible “new” disease).  New lesions on the basis of FDG-PET 
imaging can be identified according to the following algorithm:  
Negative FDG-PET at baseline, with a positive FDG-PET at follow-up is PD based on a 
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 site of disease confirmed 
by CT, this is PD.

• If the positive FDG-PET at follow-up is not confirmed as a new site of disease on CT, 
additional follow-up CT scans are needed to determine if there is truly progression 
occurring 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 site of disease on 
CT that is not progressing on the basis of the anatomic images, this is not PD.  
Time Point Response  
Below is a summary of the overall response status calculation at each time point for patients 
who have measurable disease at baseline: Patients with target (+/– non-target) disease. 
 
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 error.  This 
will also permit appropriate interpretation of results in the context of historical data where 
response has traditionally required confirmation in such trials.  However, in all other 
circumstances, (ie, in randomized phase 2 or 3 trials 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 that are not blinded. 
In the case of SD, measurements must have met the SD criteria at least once after study 
entry at a minimum interval (in general not less than 6–8 weeks) that is defined in the study 
protocol.  
Missing Assessments and Inevaluable Designation 
When no imaging/measurement is done at all 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 contribution of the individual missing lesion(s) would not 
change the assigned time point response.  This would most likely happen in the case of 
PD.  
Reporting of Results  
• All patients included in the study must be assessed for response to treatment, even if 
there are major protocol treatment deviations or if they are ineligible.  Each patient

will be assigned one of the following categories: 1) complete response, 2) partial 
response, 3) stable disease, 4) progressive disease, 5) early death from malignant 
disease, 6) early death from toxicity, 7) early death because of other cause, or 9) 
unknown (not assessable, insufficient data). 
• All the patients who met the eligibility criteria should be included in the main analysis 
of the response rate. Patients in response categories 4-9 should be considered as failing 
to respond to treatment (disease progression).  Thus, an incorrect treatment schedule

Appendix D  
Handling and Shipment of Pharmacokinetic Samples 
Blood samples will be taken for pharmacokinetic evaluation by cannula or direct 
venipuncture at the time points listed in Appendix D-1 (dose escalation phase) and 
Appendix D-2 (dose expansion phase).  The exact times and dates of blood sampling are 
to be recorded in the CRFs. 
Blood samples (2 mL) for fruquintinib pharmacokinetics will be collected into sodium 
heparinate vacutainers.  The tubes will be immediately inverted gently at least 5 times to 
mix the blood and then placed in ice bath prior to centrifugation.  The tubes will be 
centrifuged at approximately 1000 g and 4oC for 10 minutes, after which the plasma will 
be transferred immediately into 2 clean prelabeled tubes.  Approximately 0.5 mL plasma 
will be placed in each tube (Tube A and Tube B).  After the tubes are tightly capped, the 
samples should be stored immediately at -20°C or ˗80°C.  The whole process of plasma 
collection should be completed within 2 hours of the blood sampling.  According to the 
present results of plasma stability, fruquintinib can be stored at ˗20°C and at ˗80°C for 133 
days.  For long-term storage, it is recommended that the plasma samples be stored at 
˗80°C. 
Each sample will be identified by date of collection, study number, patient number and 
initials, and sample time point identifier (i.e. 30 minutes, 1 hour, 4 hours etc.).  Tube B 
samples must be labeled as “duplicate.” 
All plasma samples will be shipped on dry ice to the central laboratory within 30 days of 
sample collection.  The dry ice should be sufficient to keep the samples frozen during the 
whole shipment period.  The samples of Tube B are shipped out after the prior batch of 
Tube A has been received safely by the central laboratory.  Tube A samples will be used 
for bioanalysis.  Tube B samples will be stored in ˗80°C freezer for future use.  The 
laboratory should be notified at least 1 day prior to the arrival of the sample and be provided 
shipping details and tracking numbers for the shipment. 
Prior to shipment, a PK sample requisition form (containing the details of each 
sample/label identification included in the shipment) will be prepared.  All sample 
correspondence must contain the study number, study drug, and Site references (including 
emergency contact details and responsible shipment coordinator).  All of the sample 
details on this log must match the details included on the individual sample labels, as each 
sample label will be checked against the list by Centre Laboratories’ sample coordination 
personnel.  The log should be reviewed by the preparer and a second individual for 
accuracy and signed/dated by both individuals.  To avoid sample mix-ups or 
misidentification, the samples in the shipment will be sorted by patient number and sample 
time using segmented cartons.

Appendix F  
Fruquinitinib and Concomitant Medication 
Fruquintinib is not a substrate of efflux transporters.  Fruquintinib showed dose-
dependent inhibition on P-glycoprotein (P-gp) and breast cancer resistance protein (BCRP). 
Based on the data for digoxin transport (mediated by P-gp) and estrone-3-sulfate transport 
(mediated by BCRP), the IC50 on P-gp and BCRP was estimated to be 4.60 and 1.29 µM, 
respectively. 
According to the present metabolism data, cytochrome P450 enzymes CYP3A4/5 play an 
important role in the metabolism of fruquintinib.  Fruquintinib had no marked reversibly 
inhibitory effects on CYPs 1A2, 2B6, 2C8, 2C9, 2C19, 2D6, and 3A4/5 (IC50 >10 µM) and 
no induction of CYP1A2, 
 and CYP3A4 at the tested concentration of 10 µM.  
No marked time-dependent inhibition was observed for CYP1A2, 2B6, 2C8, 2C9, 2C19, 
2D6, and 3A4/5. 
A series of CYP3A4 strong inducers and strong inhibitors are listed in Tables F-1 and F2 
below.  Patients who received a CYP3A4 strong inducer or strong inhibitor within 
2 weeks (3 weeks for hyperforin perforatum treatment) prior to the first dose of the study 
drug will not be allowed to participate in the study. 
Typical substrates of P-gp and BCRP are listed in Table F-3 below.  During the study, 
substrates of P-gp and BCRP, and strong inducers and inhibitors of CYP3A4/5 are avoided 
to be administered concomitantly with fruquintinib, unless investigators consider it 
necessary.  In this case, efficacy reduction and toxicity increases resulting from the 
interaction should be closely monitored. 
Not all the medications are listed in the following tables.  Other drugs known to possibly 
affect CYP3A4 activity and to be substrates of P-gp and BCRP should be used with 
cautions.  When combining fruquintinib with other drugs the prescription information of 
all concomitant medications should be reviewed.

Appendix G  
Guideline to Interpreting the Causality Question 
The following factors should be considered when deciding if there is a “reasonable 
possibility” that an AE may have been caused by the drug. 
• Time Course.  Exposure to suspect drug.  Has the patient actually received the 
suspect drug? Did the AE occur in a reasonable temporal relationship to the 
administration of the suspect drug? 
• Consistency with known drug profile.  Was the AE consistent with the previous 
knowledge of the suspect drug (pharmacology and toxicology) or drugs of the same 
pharmacological class?  Or could the AE be anticipated from its pharmacological 
properties? 
• Dechallenge experience.  Did the AE resolve or improve on stopping or reducing the 
dose of the suspect drug without treatment of the reported event? 
• No alternative cause.  The AE cannot be reasonably explained by another etiology, 
such as the underlying disease, other drugs, other host or environmental factors. 
• Rechallenge experience.  Did the AE reoccur if the suspected drug was reintroduced 
after having been stopped?  HMPL would not normally recommend or support a 
rechallenge. 
• Laboratory tests.  A specific laboratory investigation (if performed) has confirmed 
the relationship? 
A “reasonable possibility” could be considered to exist for an AE where 1 or more of these 
factors exist.   
In contrast, there would not be a “reasonable possibility” of causality if none of the above 
criteria apply or where there is evidence of exposure and a reasonable time course but any 
dechallenge (if performed) is negative or ambiguous or there is another more likely cause 
of the AE. 
In difficult cases, other factors could be considered such as: 
• Is this a recognized feature of overdose of the drug? 
• Is there a known mechanism? 
Ambiguous cases should be considered as being a “reasonable possibility” of a causal 
relationship unless further evidence becomes available to refute this.  Causal relationship 
in cases where the disease under study has deteriorated due to lack of effect should be 
classified as no reasonable possibility.

Appendix H  Clinical Evaluation of Possible Drug-Induced Liver Injury (DILI) 
If ALT or AST is elevated to higher than 3 x ULN and bilirubin is elevated to higher than 
2 X ULN, fruquintinib treatment should be discontinued immediately, and supportive 
treatment should be given. T his combination of lab abnormalities meets the biochemical 
criteria for Hy’s law, which is associated with a markedly increased possibility of severe 
drug-induced liver injury (DILI), and may progress to liver transplantation or death (FDA 
Guidance for Industry - Drug-Induced Liver Injury: Premarketing Clinical Evaluation.  
FDA, 2009). 
If the biochemical criteria for Hy’s law are met, fruquintinib should be immediately 
discontinued, and patients need to be very closely monitored (bilirubin, ALP, AST, and 
ALT measured 2-3 times weekly until the results return to baseline or normal), and other 
causes of liver injury evaluated (eg, new or worsening hepatobiliary metastases; non-
malignant biliary obstruction; viral hepatitis A, B, or C; alcoholic or autoimmune hepatitis; 
preexisting or acute liver disease; ischemic liver injury; right-sided congestive heart failure; 
new or worsening liver metastases; or concomitant medication that could cause the 
observed injury).  Consultation with a gastroenterologist or hepatologist should be 
considered. 
If the biochemical criteria for Hy’s Law have been met, expedited reporting is required 
(see Section 7.1.2), before waiting for the evaluation of other causes to be completed.  
 
Recommended Data Collection for Suspected DILI 
The investigator is recommended to obtain the following information, so as to further 
evaluate and follow up and complete the clinical data.  Data should be recorded on CRFs 
where possible, and supplemented by investigator reporting as text in the clinical database: 
• 
Medical history of the patient 
o Detailed history of current symptoms, diagnosis of complications and medical 
history 
o Previous medical history (viral hepatitis, alcoholic hepatitis, autoimmune 
disease, biliary tract disease and cardiovascular disease, etc.) 
o History of concomitant medication (including OTC and prescription drugs, 
herbal medicine and dietary supplements), alcohol consumption, recreational 
drugs and special diet 
o History of exposure to potentially hepatotoxic chemicals 
• 
Complete the following laboratory tests: 
o Haematology 
o Clinical biochemistry: ALT, AST, bilirubin (including total bilirubin and 
direct bilirubin), ALP, albumin, prothrombin time or INR, amylase, fasting 
blood glucose, cholesterol and triglycerides 
o Other Serum Tests: Hepatitis A (Anti-IgM and Anti-IgG), hepatitis B (HbsAg, 
Anti-HBs and HBV DNA), hepatitis C (Anti-HCV, and HCV RNA test is 
required for any patient with positive test result), hepatitis D (Anti-IgM and 
Anti -IgG), hepatitis E (Anti-HEV and Anti-HEV IgM).

• 
Complete appropriate auxiliary examination: 
o Patients with confirmed elevation of ALT/AST combined with TBili are 
required to receive abdominal ultrasonography or other clinically applicable 
imaging examination within 48 hours (to exclude biliary tract, pancreatic, or 
intrahepatic causes, such as new or worsening hepatobiliary metastases or 
biliary calculi) and obtain the liver imaging result as soon as possible. If an 
alternative cause (such as biliary tract, pancreatic, or intrahepatic causes) of 
abnormal hepatic results cannot be confirmed by imaging, paracentesis is 
recommended for pathological examination after obtaining consent of the 
patient;  
o If suspected cardiovascular causes exist, cardiac ultrasonography is 
recommended to exclude cardiovascular dysfunction (ie, right heart failure); 
Long-term follow-up: Perform close monitoring on the patient through repetitive tests of 
ALT, AST and bilirubin (including total bilirubin and direct bilirubin) two to three times 
weekly until the laboratory ALT and/or AST abnormality becomes stable or recovers, and 
then proceed according to the protocol.

Appendix I 
Management of Hypertension in Patients Receiving Fruquintinib 
Hypertension is a common AE that has been reported in patients taking angiogenesis 
inhibitors (Izzedine, et al 2009[15]), including fruquintinib.  Grade 3 AEs have been 
reported in 16% of patients treated with fruquintinib; no Grade 4 events have been reported 
to date.  It appears that hypertension is a class-effect of VEGFR inhibitors (either 
antibodies or small molecules). 
There is no standard therapy for angiogenesis inhibitor-induced hypertension because there 
have not been any published controlled clinical trials with specific agents.  Therefore, one 
can take an approach based on the clinical characteristics of particular patients.  Calcium 
channel blockers and angiotensin converting enzyme inhibitors (ACEI) are a reasonable 
first choice in most cases.  For patients with proteinuria, chronic renal disease or 
metabolic disease, an ACE inhibitor or angiotensin II receptor blockers (ARB) may be 
preferred; for elderly patients, dihydropyridine calcium channel blockers may be preferred.  
In this appendix is a summary of the most recent American Heart Association 
(AHA)/American College of Cardiology (ACC) hypertension treatment guidelines.  A 
cardiologist may be consulted if appropriate. 
The objective of antihypertensive therapy in general is to control the blood pressure to a 
target level <140/90 mmHg.  For high-risk populations, such as patients with chronic 
renal disease and/or diabetes, it may be appropriate to aim for a target blood pressure < 
130/80 mmHg.  On the following two pages, please see a summary of the most recent 
AHA/ACC hypertension treatment guidelines.

If hemorrhagic events are evaluated as severe (CTCAE Grade ≥3) or serious adverse events, 
fruquintinib treatment should be discontinued or interrupted immediately, and appropriate 
treatment measures initiated to control bleeding (e.g. transfusion, radiologic, endoscopic, 
or elective operative intervention as indicated).  When the patient is not well enough to 
tolerate an invasive procedure or operation, best supportive care is given (see 
Section 5.2.2.1, Table 13, Dose Adjustment for Hemorrhage at any Site).  Patients need 
to be very closely monitored, both clinically (continuously), and by relevant laboratory 
testing (INR, aPTT, platelet count, hemoglobin) every 2-3 days until the results return to 
baseline or normal).  During the initial assessment, a focused history and physical 
examination, with collection of vital signs and laboratory evaluation and imaging 
evaluation should be obtained, aimed at determining the time of onset, location, severity of 
bleeding, and whether bleeding is ongoing.  Clinicians should be mindful of 
comorbidities 
and 
concomitant 
treatments 
(eg. 
anti-platelet 
therapy 
and/or 
thrombocytopenia, or liver disease) that could also contribute to bleeding and manage them 
as appropriate.  Consultation with other department clinicians should be considered when 
necessary. 
The investigator should closely monitor patients receiving anti-platelet and/or anti-
thrombotic drugs during study drug treatment and make a timely decision on whether to 
continue or stop such drugs in patients that report Grade ≥2 hemorrhagic events at any site, 
based on an individual assessment of the risk-benefit balance. 
If a hemorrhagic event is evaluated as a severe (CTCAE Grade ≥3) or serious adverse event 
after taking fruquintinib, the investigator is required to report the event in an expedited 
fashion (within 24 hours of first awareness) to sponsor (see Table 12 and Section 7.2 
Expedited Reporting Requirements).  
See the Management Flowchart below for guidance on the management of severe or 
serious hemorrhage at any site. 
Recommended Data Collection for Severe or Serious Hemorrhagic Events: 
The investigator is recommended to obtain the following information, so as to further 
evaluate and follow up and complete the clinical data.  Data should be recorded on 
SAE/AESI report form where possible, and supplemented by Bleeding Event Follow-Up 
Questionnaire: 
• Medical history of the patient 
o Detailed history of current symptoms, diagnosis of complications and medical 
history  
o Previous medical history  
o History of concomitant medication ( 
 Vitamin K antagonists (e.g. warfarin) 
 NSAIDs (e.g. aspirin) 
 Anti-platelet drugs (e.g. clopidogrel/glycoprotein GPIIb/IIIa 
inhibitors/dipyridamole) 
 Other anticoagulants (e.g. heparin/thrombolytics/SSRIs) 
 Food and herbal supplements with anticoagulant property

 Immunosuppressants 
 alcohol consumption 
 Recreational drugs and special diet  
o Family history of bleeding events 
• Complete the following laboratory tests: 
o Hematology: hemoglobin, platelet, hematocrit, reticulocyte count 
o Clinical biochemistry: bleeding time, prothrombin time, aPTT, INR  
• Complete appropriate auxiliary examination: 
o Patients with confirmed bleeding are required to receive upper or lower GI 
endoscopy, bronchoscopy or other clinically applicable procedure or 
radiologic imaging within 48 hours, to confirm the site of bleeding.  
o If suspected cardiovascular causes exist, cardiac ultrasonography is 
recommended to exclude cardiovascular dysfunction (ie, right heart failure).

Protocol Amendment History 
Amendment 3, Version 3: 
The protocol was amended on July 2, 2018 to add a cohort of 30 patients with metastatic 
colorectal cancer (mCRC) to the expansion phase of this study.  At the time of writing the 
Amendment 3, the Safety Review Committee (SRC) had determined that the recommended 
Phase 2 dose (RP2D) of fruquintinib is 5 mg QD (3 weeks on/1 week off each 28-day 
cycle).  The study population in the expansion phase therefore included both the 
originally planned cohort of 6 patients with advanced solid tumors of any type (Cohort A) 
and a new cohort of 30 patients with metastatic colorectal cancer mCRC (Cohort B).  The 
basis for adding 30 patients with mCRC was the positive Phase 3 study FRESCO 
conducted in China that demonstrated a significantly increased overall survival in patients 
with mCRC treated with fruquintinib compared to placebo, and led to approval of 
fruquintinib for this indication by the CFDA.  Another reason for Amendment 3 was to 
correct the terminology used in the original protocol to describe the dose escalation phase 
of the study as a safety run-in phase.  The correct terminology was changed to “dose 
escalation phase” because the study was not prospectively designed as the safety-run in 
phase in a Phase 2 trial. 
The changes in Amendment 3 are summarized in the table below.

QD, and if not tolerated, then a second reduction 
from 4 mg QD to 3 mg QD. Patients starting at 3 mg 
QD are allowed to have one reduction, ie, from 3 mg 
QD to 2 mg QD. The lowest dose level permitted in 
the study is 2 mg (see Table 7). 
5.3.1 
Concomitant 
Therapies 
The following text was changed:  
• 
Patients who are receiving low-dose warfarin or 
Coumadin-like products should have their INR 
monitored and maintained at the lower third of the 
therapeutic range (ie, 2.0-2.3) unless a higher INR is 
required for anti-thrombotic efficacy. 
Section 6.1.2 
Physical 
Examination 
Added the following text to the paragraph describing the 
limited physical examination: In order to assess changes 
from baseline and screen for new abnormalities, the 
limited physical examination should assess for new or 
changed skin lesions, enlarged nodes, palpable masses, 
hepatomegaly, and splenomegaly. Patient-reported 
symptoms should be directed to address the symptoms.

Analysis 
Populations 
Added text to define the Efficacy Analysis Set (EAS) as all 
patients who have received at least 1 dose of fruquintinib 
and have had at least 1 post-baseline tumor assessment. 
All efficacy endpoints will be analyzed will based on this 
analysis set. 
Section 8.5 
Efficacy Analysis 
• 
Added text to identify the efficacy endpoints, 
including the objective response rate (ORR), 
duration of response (DoR), progression free survival 
(PFS), and overall survival (OS).  
• 
Added text to specify that efficacy data will be listed 
and summarized by dose cohort and disease type.  
• 
Added text to specify that ORR and DCR will be 
summarized with percentages and 95% exact 
confidence intervals. The PFS rate at 12 weeks and its 
95% confidence intervals will be estimated by the 
Kaplan-Meier method. PFS, DoR, and OS will be 
summarized descriptively using Kaplan-Meier 
medians and quartiles. Percentage change in tumor 
size from baseline will be determined for patients 
with measurable disease at baseline and derived at 
each visit by the percentage change in the sum of the 
diameters of target lesions (TLs) compared to 
baseline. Best percentage change in tumor size will be 
summarized using descriptive statistics and presented 
using a waterfall plot. 
• 
Added text to stipulate that a best overall response of 
PR or CR, changes in tumor measurements must be 
confirmed by repeat assessments no less than 4 weeks 
after the criteria for response are first met. 
•

Tumor-assessment related 
endpoints, ORR, DCR and

based on ERS. PFS will be 
summarized for SAS. 
Objective Response Rate 
(ORR) 
The objective response rate 
(ORR) will be estimated only 
for patients with disease that 
is measurable by RECIST 
(v.1.1, see Appendix C). The 
ORR is defined as the number 
(%) of patients with at least 
one response of CR or PR at a 
study visit that is confirmed at 
least 
4 weeks later. Data obtained 
up until progression, or the last 
evaluable assessment in the 
absence of progression, will be 
included in the assessment of 
ORR. However, any CR or PR 
which occurs after the patient 
has received an anticancer 
therapy other than fruquintinib 
anticancer 
will not be included in 
numerator of the ORR 
calculation. 
Progression Free Survival (PFS) 
Progression free survival (PFS) 
is defined as the time from date 
of first dosing until the date of 
an objective disease progression 
as defined by RECIST 1.1 or 
death (by any cause in the 
absence of progression) 
regardless of whether the 
patient withdraws from the 
fruquintinib therapy. Patients

according to RECIST 1.1. 
ORR will be calculated based on 
the REAS. Proportions of subjects 
with ORR will be presented by 
dose group along with exact 
confidence intervals. 
Progression Free Survival (PFS) 
Progression free survival (PFS) is 
defined as the time from date of 
first dose of study drug until the 
date of an objective disease 
progression as defined by 
RECIST 1.1 or death for any 
reason. Patients who have not 
progressed or died at the time of 
analysis will be censored at the 
time of the last tumor assessment. 
The censoring rule for PFS will 
be detailed in the Statistical 
Analysis Plan (SAP). 
PFS will be summarized by dose

who have not progressed or

their last evaluable RECIST 
assessment. However, if the 
patient progresses or dies after 
two or more consecutive missed 
tumor assessment visits, the 
patient will be censored at the 
time of the latest evaluable 
RECIST assessment. If the 
patient has no evaluable tumor 
assessment visits after first dose 
of study treatment or does not 
have evaluable baseline tumor 
assessment data the patient will

prior to documented disease 
progression or death on study, 
will be censored at the date of

anticancer treatment. 
Duration of Response (DoR) 
Duration of response (DoR) 
will be defined as the time from 
the date of the first documented 
response, (that is subsequently 
confirmed) until the date of the 
documented progression or of 
death in the absence of disease
