other criteria for discontinuation of treatment as specified in the 
protocol, whichever occurs first. When the subject develops 
disease progression that conforms to the definition by RECIST 
v1.1 according to the investigator's assessment, and BIRC also 
confirms the disease progression (according to RECIST v1.1), if 
the investigator assesses that the subject still has clinical benefit 
and is tolerated to study treatment, subject will continue SHR-
1210 alone or in combination with rivoceranib (experimental 
arm) or sorafenib (control arm) (see Section 6.6 of the main text 
for continued treatment after progression);  
• Specific timing of tumor assessment clarified: Tumor radiological 
assessment will continue until the occurrence of disease 
progression confirmed by BIRC according to RECIST v1.1 
criteria or study treatment termination, whichever occurs later. 
Subjects who discontinues treatment for other reasons than 
BIRC-confirmed disease progression (according to RECIST 
v1.1) will also continue with regular follow-up by tumor 
radiological assessments after treatment is completed. If the 
subject withdraws the informed consent before BIRC confirms 
the disease progression according to the RECIST v1.1 criteria or 
the treatment is discontinued, other anti-tumor treatment has 
begun (except for traditional Chinese medicine), or the subject 
dies, there is no need to continue the radiological evaluation. If 
the subject does not meet the above criteria for stopping 
radiological assessment, the efficacy evaluation of the three

Study Design 
This is a randomized, open-label, international, multi-center, 
phase 3 trial to evaluate the efficacy and safety of PD-1 
antibody SHR-1210 plus rivoceranib mesylate versus sorafenib 
as first-line therapy in subjects with incurable advanced HCC.  
The study will be conducted in subjects with incurable, locally 
advanced or metastatic HCC who have not received previous 
systematic treatment. Primary efficacy endpoints include both 
OS and PFS evaluated by the BIRC based on RECIST v1.1, and 
approximately 510 subjects will be enrolled. Eligible subjects 
will be randomized to receive either SHR-1210 combined with 
rivoceranib mesylate (experimental arm) or sorafenib (control 
arm) in a 1:1 ratio.  
The stratification factors for randomization include:  
1. Macrovascular invasion and/or extrahepatic metastasis 
(presence vs. absence) 
2. Geographical region (Asia vs. countries outside of Asia) 
3. Baseline AFP (AFP < 400 ng/mL vs. AFP ≥ 400 ng/mL)

Subjects will receive study treatment after being informed of 
all pertinent aspects of the study, signing the informed consent 
form and passing the screening for eligibility. Experimental 
arm: SHR-1210, 200 mg, via intravenous infusion, once every 
two weeks (Q2W) + rivoceranib 250 mg, p.o., once per day 
(QD), continuously, 4 weeks (28 days) per cycle of therapy. 
Control arm: sorafenib, 400 mg, p.o., twice per day (BID), 
4 weeks (28 days) per cycle of therapy. Study treatment will 
continue until the subject develops an intolerable toxicity, 
withdrawing informed consent, disease progression confirmed 
by BIRC according to RECIST v1.1 (when the subject has 
disease progression assessed by the investigator according to 
RECIST v1.1, the investigator must submit the radiological 
data to BIRC immediately. If BIRC evaluates it as non-disease 
progression according to RECIST v1.1, the subject should 
continue to receive the study drug treatment and continue the 
tumor radiological evaluation; if BIRC confirms it as disease 
progression based on RECIST v1.1, the investigator needs to 
assess whether the subject still has clinical benefit. If the 
subject is considered to still have clinical benefit and meets the 
criteria for continuing treatment beyond the disease progresses 
[see Section 6.6 for details], the subject may continue to receive 
study treatment; if the subject is no longer considered to have 
clinical benefit, the treatment should be discontinued) or other 
discontinuation criteria specified in the protocol, whichever 
occurs first. Upon approval of Protocol v6.0, disease 
progression will not be evaluated by BIRC anymore, and will 
only be confirmed by the investigator per RECIST v1.1.  
Subjects will have safety visits on D1 and D15 of each cycle of 
therapy within the first 3 cycles for both arms. From Cycle 4 
onwards, subjects will have safety visits on D1 and D15 of each 
cycle in the experimental arm, and on D1 of each cycle in the 
control arm; refer to the SCHEDULE OF ACTIVITIES for 
details. Subjects will continue to have safety follow-up and 
survival follow-up after the study treatment discontinuation. 
Tumor radiological examination will be performed once every 
8 weeks to evaluate efficacy for the first 48 weeks from 
randomization, and once every 12 weeks thereafter. During the 
study period, radiological examination and evaluation can be 
added at any time if clinically indicated. Tumor radiological 
assessment will continue until the occurrence of disease 
progression confirmed by BIRC according to RECIST v1.1 
criteria or treatment discontinuation, whichever occurs later. 
Subjects who discontinue treatment for reasons other than 
BIRC-confirmed disease progression (according to RECIST 
v1.1) will also continue with regular follow-up by tumor 
radiological assessments after study treatment is discontinued.

Before BIRC confirms the disease progression according to the 
RECIST v1.1 criteria or the study treatment is discontinued, if 
the subject withdraws the informed consent, other anti-tumor 
treatment has begun (except for traditional Chinese medicine), 
or the subject dies, there is no need to continue the radiological 
evaluation. If the subject does not meet the above criteria for 
stopping radiological assessment, the efficacy evaluation of the 
three efficacy evaluation criteria (RECIST v1.1, mRECIST, 
imRECIST) needs to continue even if the disease progression 
under certain efficacy evaluation criteria occurs.  
The study extension phase will be initiated when sufficient 
follow up is completed and the study is ended (at least 2 years 
follow up of the last subject randomized). The purpose of the 
extension phase is to continue to provide access to study drugs 
for subjects who are still on study treatment and still derive 
clinical benefit at the time of study closure. Upon initiation of 
the extension phase, the Sponsor considers the safety and 
efficacy profile of the experimental treatment regimen within 
this study to have been sufficiently established and data 
analysis required for regulatory purposes have been completed. 
The study will establish a Data Monitoring Committee (DMC) 
to regularly monitor safety of the subjects on a periodic basis 
and evaluate efficacy and safety data at the time of PFS 
analysis and OS interim analysis. The DMC will make 
recommendations for continuing, revising or terminating the 
study based on observed safety or efficacy data. The 
composition, responsibilities, operation and management of 
the DMC will be detailed in a separate DMC charter.

than 20 minutes, no more than 60 minutes) once every 
two weeks. One treatment cycle is 4 weeks (28 days). 
Where possible, completion of the administration

should be done prior to ECG assessment. 
On days of rivoceranib PK blood collection (Day 1 of 
Cycle 1-4: C1D1, C2D1, C3D1 and C4D1), it is 
necessary to administer rivoceranib first at the study 
center, followed by SHR-1210 administration. For 
specific information, refer to the SCHEDULE OF 
ACTIVITIES and BLOOD SAMPLE COLLECTION 
TABLE. 
Control Arm: 
Sorafenib 400 mg is administered orally under fasted 
state (at least 1 hour prior to meal or 2 hours after meal), 
twice per day, continuously.  
One treatment cycle is 4 weeks (28 days). 
If a subject in the experimental arm (SHR-1210 in combination 
with rivoceranib) develops a treatment-related AE that leads to 
permanent discontinuation of rivoceranib and the investigator 
determines that the subject can benefit from SHR-1210 as 
monotherapy, the subject is allowed to continue to receive 
SHR-1210 monotherapy until the criteria for study treatment 
discontinuation as specified in the protocol has been met, and 
vice versa. In addition, during the study treatment period, if a 
subject in the experimental arm develops a treatment-related 
AE that leads to temporary discontinuation of SHR-1210 or 
rivoceranib, the subject may continue to receive monotherapy. 
The combination therapy can be resumed only after the 
treatment-related toxicity resolves. 
Subjects continue to receive study treatment until intolerable 
toxicity occurs, withdrawal of informed consent, disease 
progression confirmed by BIRC according to RECIST v1.1 and 
lack of clinical benefits as determined by investigator after 
comprehensive evaluation of radiological and laboratory 
examination data as well as the subject’s clinical condition 
(e.g., 
tumor 
symptomatic 
exacerbation) 
or 
other 
discontinuation criteria specified in the protocol, whichever 
comes first. Upon approval of protocol V6.0, disease 
progression will only need to be confirmed by investigator per 
RECIST v1.1. 
When a subject develops disease progression that conforms to 
the definition of RECIST v1.1 according to the investigator's 
assessment, and BIRC also confirms that disease progression 
(according to RECIST v1.1), subject may continue treatment 
with SHR-1210 monotherapy or in combination with 
rivoceranib (experimental arm) or sorafenib (control arm), if 
the subject still has clinical benefit and can tolerate study 
treatment as determined by investigator (see Section 6.6 for 
treatment criteria after disease progression).

PK And 
Immunogenicity 
Sampling  
Immunogenicity and PK measurement will be assessed in the 
experimental arm only. 
Pre-dose sampling: blood samples will be collected once within 
0.5 hours prior to rivoceranib administration on Day 1 from 
Cycle 1 to Cycle 4 (C1D1, C2D1, C3D1, C4D1); and collected 
once within 0.5 hours prior to rivoceranib administration on 
Day 1 of every 3 cycles afterwards. A blood sample will be 
collected 30 days (±7 days) after the last administration of 
SHR-1210. When SHR-1210 is interrupted for longer than 30 
days and finally is confirmed to be unable to resume, subjects 
are required to return for a site visit as early as possible for a 
blood sample to be collected. If the subject has started other 
anti-tumor therapy, it’s not necessary to collect the 
immunogenicity blood sample at 30 days (±7 days) after the 
last administration of SHR-1210. If SHR-1210 and/or 
rivoceranib 
is 
temporarily 
interrupted, 
pre-dose 
immunogenicity and PK sample will be collected on schedule. 
If only rivoceranib is temporarily interrupted at the sampling 
time above, and the blood sample should be collected within 
0.5 hours before the administration of SHR-1210. The above 
samples will be used to measure the blood concentration and 
immunogenicity of SHR-1210, and the plasma concentration of 
rivoceranib in the C2D1-C4D1 samples. The exact time of the 
previous administration of rivoceranib (as provided by the 
subject) will be collected for C2D1, C3D1 and C4D1. 
ECG blood sampling: ECG examination will be performed 2.5 
hours (±1 hour) after the end of the rivoceranib administration, 
and blood will be collected within 15 minutes after the ECG 
examination on the first day from C1 to C4. If rivoceranib is 
interrupted, blood samples within 15 minutes of ECG will not 
be collected. The samples above will be detected for the 
concentrations of rivoceranib only. 
The actual sampling time, the actual administration time of 
SHR-1210 and rivoceranib will be recorded on the day of 
sampling. Pre-dose sampling and ECG blood sampling will not 
be performed in the extension phase (refer to BLOOD 
SAMPLE COLLECTION TABLE).

Treatment 
Discontinuation 
subject withdrawal from the study. Subjects who discontinue 
the study treatment should complete the remaining study visits 
as required in the protocol. Subjects should discontinue study 
treatment when any of the following conditions occurs:  
 Subject requests discontinuation of study treatment;  
 Efficacy evaluation meets disease progression criteria 
confirmed by BIRC (according to RECIST v1.1) 
(disease progression will be confirmed by the 
investigator per RECIST v1.1 upon approval of 
Protocol v6.0) unless investigator judges that the 
subject will continue to benefit from the treatment and 
the criteria for treatment beyond progression is met 
(see Section 6.6 of the protocol); 
 Pregnancy in female subject occurs during the study; 
 Unacceptable toxicity despite dose modification, or 
occurrence of adverse event, abnormal laboratory 
examination, or concomitant diseases, then it is no 
longer in the best interests of the subjects to continue 
study treatment according to the judgment of the 
investigator; 
 Overall deterioration of health status, inability to 
continue participation in the trial;  
 Significant protocol deviation or violations confirmed 
by sponsor, e.g., ineligibility of subjects after 
enrollment;  
 Termination of study by the sponsor; 
 Other reasons for inability to continue study treatment 
as considered by investigators.  
Criteria for 
Withdrawal from 
the Study 
The reasons for withdrawal from the study may include:  
 Withdrawal of the informed consent upon participation 
in the study, and refusal of further follow-up;  
 Other conditions that necessitate the withdrawal from 
the study, as considered by investigators, for example, 
loss of the ability to express his/her wishes freely due 
to imprisonment or segregation;  
 Lost to follow-up;  
 Termination of study by the sponsor. 
Criteria for Study 
Termination 
The criteria for termination of this study include but not 
limited to the following:  
 Discovery of unexpected, significant or unacceptable 
risk;  
 The efficacy data support early termination of the 
study; 
 Low compliance with study requirements.

Safety Evaluation 
The severity of adverse events will be judged in accordance 
with CTCAE v4.03. Adverse event (AE) record forms should 
be filled out during the trial, including the occurrence time, 
severity, relationship with the study drug, duration, measures 
taken and outcome of the AE.  
Efficacy 
Evaluation 
To evaluate OS (co-primary efficacy endpoint), subjects after 
study treatment discontinued will have their survival status 
collected through site visits or telephone follow-up on a regular 
basis until death. Subject who died during the trial, their actual 
time of death will be recorded. 
PFS: defined as the time from the date of randomization to the 
first occurrence of radiological progression or death, whichever 
comes first. Evaluations of PFS (another primary efficacy 
endpoint) as well as TTP, ORR, DCR and DoR (secondary or 
exploratory efficacy endpoints) will be performed based on 
RECIST v1.1, mRECIST and imRECIST: From randomization 
to 48 weeks, the radiological evaluation will be performed once 
every 8 weeks; once every 12 weeks thereafter; and can be 
performed in a real-time manner if new lesion is suspected; the 
tumor response must be confirmed in 4 weeks or at next 
scheduled timepoint for the subjects who are initially evaluated 
as PR/CR. When suspected clinical progression occurs, 
physical examination and confirmation by radiological 
evaluation should be performed as soon as possible, rather than 
waiting until the next scheduled imaging examination. 
When progression of disease is confirmed by investigator 
according to RECIST v1.1, the investigator must submit the 
radiological data to BIRC immediately for evaluation of 
disease progression. If BIRC confirms non disease progression 
according to RECIST v1.1, the subject should continue with 
study treatment and tumor radiological evaluation; if BIRC 
confirms as disease progression according to RECIST V1.1, the 
investigator should evaluate whether the subject still has 
clinical benefit, if the subject is considered to have clinical 
benefit from study treatment and meet criteria for continuation 
of treatment after the disease progresses (see Section 6.6 for 
details), the subject may continue study treatment and efficacy 
assessment as originally scheduled. 
Tumor radiological assessment should continue until disease 
progression confirmed by BIRC according to RECIST v1.1 or 
treatment discontinuation, whichever occurs later. Subjects 
who discontinue study treatment for reasons other than BIRC-
confirmed disease progression (according to RECIST v1.1) 
must continue with their regular follow-up tumor radiological 
assessments. Prior to BIRC confirmed disease progression 
according to the RECIST v1.1 or discontinuation of study 
treatment, if the subject has withdrawn informed consent,

started other anti-tumor treatment (except for traditional 
Chinese medicine), or subject died, no further imaging 
assessment is required. If subject does not meet the above 
criteria for stopping radiological assessment, tumor efficacy 
evaluation of the three efficacy evaluation criteria (RECIST 
v1.1, mRECIST, imRECIST) needs to continue even if the 
disease progression under certain efficacy evaluation criteria 
occurs.  
Upon approval of Protocol v6.0, disease progression will be 
confirmed by the investigator per RECIST v1.1, and tumor 
assessments evaluated by BIRC per mRECIST will not be 
performed afterwards. If the investigator confirms non-disease 
progression, the subject should continue on study treatment and 
tumor radiological evaluation as required; if the investigator 
confirms as disease progression, the subject may continue to 
receive study treatment after disease progression at the 
investigator’s discretion (see Section 6.6). 
Sample Size 
Determination 
Assuming a 1:1 randomization between sorafenib and SHR-
1210+rivoceranib, and a median PFS time of 3.6 months for 
subjects in the sorafenib group and a median PFS of 6 months 
for a subject in the combination group, 332 PFS events will be 
sufficient to detect a hazard ratio (HR) of 0.60 with 98% power 
based on Log-rank test at significance level of 0.005 one-sided. 
Similarly, assuming a median survival time of 10.5 months for 
subjects in the sorafenib group and a median time of 14.6 
months for subjects in combination group, 359 OS events will 
be sufficient to detect a hazard ratio (HR) of 0.72 with 85% 
power based on Log-rank test at significance level of 0.020 
one-sided. Assuming an accrual period of 18 months, total 
duration of 36 months and 19 months for the OS and PFS, 
respectively, and probability of subject loss at approximately 
10% per 12 months and per 6 months for the OS and PFS 
respectively, a sample size of 510 subjects will be enrolled for 
the study. Power and sample calculations were performed using 
EAST® 6.4.1. software package.

is one planned analysis, which is expected to occur when 332 
PFS events are observed at ~19 months after first subject 
enrolled. The OS will be evaluated in the following time points: 
when PFS is analyzed; when 251 OS events are observed (70% 
at ~ 23 months after first subject enrolled) and when 359 OS 
events are observed at 36 months after first subject enrolled. 
The hypothesis testing of OS and PFS will be evaluated by 
comparing SHR-1210 plus rivoceranib to sorafenib on events

in the ITT using a stratified Log-rank test (based on 
randomization stratification factors). The hazard ratio 
(HR=SHR-1210 plus rivoceranib / sorafenib) and the 
corresponding 95% confidence interval (CI) will be estimated 
in a stratified Cox proportional hazard model with treatment 
group and randomization stratification factors included in the 
model. The survival curve for each treatment group will be 
estimated using the Kaplan-Meier (KM) product-limit method. 
A 95% CI for median survival time will be estimated by 
Brookmeyer-Crowley method.  
Objective response rate (ORR) assessed by BIRC according to 
RECIST v1.1 will be analyzed as a key secondary endpoint and 
will be analyzed when 70% OS events are observed. If both 
PFS and OS primary endpoints are positive, comparison 
between treatment groups in ORR by BIRC according to 
RECIST v1.1 will be performed using stratified Cochran-
Mantel-Haenszel (CMH) test. Difference in proportions for 
ORR and its 95% CI using normal approximation will be 
provided. Overall response rates and their corresponding 95% 
exact CIs will be calculated by Clopper-Pearson method for 
each treatment group.  
The other time-to-event endpoints will be estimated using the 
Kaplan-Meier (KM) product-limit method, unless specified. A 
95% CI for median survival time will be estimated by 
Brookmeyer-Crowley method, if necessary.  
For other binary variables, stratified CMH test will be used and 
two-sided 95% CI for treatment difference will be calculated 
using normal approximation. 
Safety Analyses 
Safety data including AEs and laboratory results will be 
summarized descriptively using summary statistics. 
Other Analyses: 
Exploratory endpoints including average scores and its change 
from baseline obtained from EORTC QLQ-C30 and EORTC 
QLQ-HCC18 will be summarized descriptively using summary 
statistics. 
Biomarkers (e.g. the expression level of PD-L1 and proportion 
of strong expression of PD-L1 in tumor tissue) will be 
summarized using descriptive statistics, and an ad hoc analysis 
will be performed if required.  
Population pharmacokinetics, drug exposure-QTc analysis and 
drug exposure-response relation will be analyzed and reported 
separately. 
End of Study 
For this study, end of study is defined as the date when the last 
subject randomized has been followed for at least 2 years.  
Subject who are still on treatment at the time of study closure

Note: Except the test items and time points listed in the table, the investigator may add necessary examinations at any time. The test results will be filled in the section of 
“Examinations at Unscheduled Visits” in the CRF.  
[1] 
Screening period (Day -28): baseline data will be collected after signature of informed consent form and no longer than 28 days before start of study drug; if routine 
radiological evaluation of tumor has been performed prior to signature of the informed consent, it is unnecessary to repeat these scans during screening period in cases 
where these enhanced CTs or MRIs are completed within 28 days prior to the start of study drug (bone scan within 42 days prior to the start of study drug is acceptable). 
All baseline evaluations will be based on the results collected closest to the start of study drug.  
[2] 
Screening period (Day -14): physical examination, vital signs, ECOG-PS score and laboratory examinations (including fecal occult blood, thyroid function, 
alpha- fetoprotein, and virology), 12-lead ECG and echocardiography (including LVEF) to be collected within 14 days prior to the first dose, following the signature of 
informed consent form. All baseline evaluations will be based on the results collected closest to the start of study drug. 
[3] 
Screening period (Day -7): following the signature of informed consent form, data on hematology, urinalysis, blood chemistry, blood electrolytes, coagulation parameters, 
blood HCG (for women of childbearing potential) and Child-Pugh class must be collected within 7 days prior to the first dose. All baseline evaluations will be based on 
the results collected closest to the start of study drug. Subjects with screening failure can be re-screened. They must sign the informed consent form again, re-register and 
obtain a new subject number at the re-screening. Subjects can only be re-screened once.  
[4] 
Treatment period: data on hematology, urinalysis, blood chemistry and blood electrolytes will be evaluated within 72h prior to administration of study drug during the 
scheduled visit; ECOG-PS score, physical examination and vital signs will be evaluated within 24h prior to administration of study drug during the scheduled visit (they 
are not needed on C1D1 in cases where they are completed within 24h prior to the first dose during the screening period). In the event of a dose delay, the required 
examinations at each corresponding visit during study treatment should be scheduled as planned or more frequently if clinically indicated (Immunogenicity, concentrations 
of SHR-1210 and rivoceranib, and patient reported outcomes should be collected at respective treatment cycles as specified in Footnotes [31] [32] [35]).  
[5] 
End-of-treatment visit: Only after permanent discontinuation of both drugs (SHR-1210 and rivoceranib), the end-of-treatment visit shall start. End-of-treatment visit 
includes ECOG performance, C-P score, vital sign, physical examination, 12-lead ECG, hematology, urinalysis, blood biochemistry, blood electrolytes, coagulation, 
thyroid function, fecal occult blood test, virology, APF, HCG, subject’s self-evaluation and tumor imaging evaluation. If tumor imaging evaluation completed within 4 
weeks prior to end-of-treatment visit, or the other examinations of end-of-treatment visit completed within 7 days, then these study procedures would not be necessary to 
be repeated. For subjects who enter the extension phase after the end of study, all of the subject’s data occurring prior to extension phase need to be captured into CRFs 
and EOT visit needs to be performed even the subjects continue on study treatment (detailed instruction for data entering, refer to CRF completion guideline), the EOS 
page in CRFs for extension subjects should be collected as well before entering the extension phase. If planned schedule visit occurred within 7 days before the time of 
extension phase initiation or the relevant examinations for end of treatment visit completed within 7 days, these study procedures would not be necessary to be repeated 
on EOT. 
[6] 
Safety follow-up: Subject who completed end-of-treatment visit (after permanent discontinuation of both drugs) will have safety follow-up after last dose. It will end 90 
days after the last dose of SHR-1210 (non-serious AE unrelated to study drug will only be collected for 30 days after the last dose) or 30 days after the last dose of 
rivoceranib in experimental arm (whichever comes later); and 30 days after the last dose of study drug in sorafenib (control) arm. The first safety follow-up should start 
30 days (±7 days) after the last dose of study drug and must be performed at the study center, regardless of initiation of new antitumor therapy. A telephone visit will be 
performed 60 days (±7 days) and 90 days (±7 days) after the last dose of study drug in the experimental arm for survival status, subsequent antitumor therapy, concomitant

medications/therapy and AEs/SAEs collection (see Section 8.3 for details). When developing a safety follow-up plan, ensure that a visit is scheduled at this point in the 
safety follow-up period. If the date of the previously completed end-of-treatment visit has exceeded the safety follow-up period, there is no need to schedule a safety 
follow-up. For the subjects in experimental arm, if the date of completed end-of-treatment visit has exceeded the first safety follow-up (30 days after the last dose), but 
the safety follow-up period has not been reached, the subject does not need to go to the site for safety follow-up, and 1-2 telephone visits can be scheduled during the 
safety follow-up period. At this time, ensure that the interval between visits should not exceed 44 days, and a telephone visit should be conducted at this time point of the 
safety follow-up period. 
[7] 
Survival follow-up: the subject will enter survival follow-up period after the end of safety follow-up period. the telephone follow-up will be performed 30 days (±7 days) 
after last safety follow-up for the first survival follow-up, after that, the frequency was once every 30 days (±7 days), collecting of data on survival and subsequent 
antitumor treatment.  
[8] 
Signature of informed consent form: the informed consent on enrollment into this study needs to be completed during screening period. Prior to acquisition of the written 
informed consent form, no screening procedures specified in the study can be performed; there are special provisions on the baseline radiological examination of tumor, 
please refer to the note in radiological evaluation for tumors in this flow chart for details. Subjects with screening failure prior to treatment are allowed to have another 
opportunity for screening in this study and must repeat the informed consent and register again for a new subject number at re-screening.  
[9] 
Tumor history: including previous history of HCC, history of present illness, initial diagnosis, pathological diagnosis, data on radiological examination, course of treatment 
(e.g., surgery, interventional therapy, local ablation, and radiotherapy).  
[10] Other medical history: including history of drug allergy, history of diagnosis and treatment for other significant concomitant disease, history of tumors except 
hepatocellular carcinoma, and history of alcohol consumption etc.  
[11] Child-Pugh class: will be performed within 7 days prior to the first dose during the screening period, on Day 1 of each cycle in Cycles ≥ 2 during the treatment period, at 
end-of-treatment visit and safety follow-up. 
[12] ECOG-PS score: will be performed within 14 days prior to the first dose during the screening period, prior to administration on Day 1 of the subsequent cycles of therapy, 
at end-of-treatment visit and safety follow-up.  
[13] Physical examination: including height (only for initial examination), body weight, head and face, skin system, lymph nodes, eyes (sclera, pupil), otolaryngology, mouth, 
respiratory system, cardiovascular system, abdomen, genitourinary system, musculoskeletal system, neurological and mental status. A full physical examination will be 
performed in the screening period, and only body weight and important sites (including skin, respiratory system, cardiovascular system, abdomen and mental state) will 
be examined during the study. Physical examination will be performed within 14 days prior to first dose during the treatment period (experimental arm: prior to 
administration on Day 1 and 15 of each cycle of therapy; control arm: prior to administration on Day 1 and 15 of each cycle in Cycle 1-3, prior to administration only on 
Day 1 from Cycle 4), at end-of-treatment visit and safety follow-up. Note: except for the physical examination during the screening period and end-of-treatment visit, it 
is not necessary to record complete results of physical examination in the eCRF during the trial, and only weight and abnormal results need to be recorded. In addition, 
physical examination of reactive capillary endothelial proliferation needs to be performed in the experimental arm, occurrence sites, such as the skin, oral mucosa, nasal 
mucosa, etc., should be recorded in the eCRF in detail. Reactive capillary endothelial proliferation will be followed up until it is resolved, other reasonable time points 
(e.g., loss of follow-up, death), or reached to a stable state without any expectation of recovery.

[14] Vital signs (5 minutes after resting state/sitting still): including temperature (whenever possible, the same method of measurement should be used throughout), blood 
pressure (which needs to be measured and recorded at least twice to get the mean value as the blood pressure value), pulse rate and respiratory frequency. Vital signs will 
be performed within 14 days prior to first dose, during the treatment period (experimental arm: prior to administration on Day 1 and 15 of each cycle of therapy; control 
arm: prior to administration on Day 1 and 15 of each cycle in Cycle 1-3, prior to administration only on Day 1 from Cycle 4), at end-of-treatment visit and safety follow-
up.  
[15] Virology: HIV-Ab (screening period only), HBV and HCV test should be included. Screening period: all subjects will be required for HBV serology test by five hepatitis 
B markers (HBsAg, HBsAb, HBcAb, HBeAg, HBeAb), HBV-DNA will be quantified if the HBsAg or HBcAb test is positive. All subjects will be required for HCV-Ab 
test, and HCV-RNA will be quantified if the HCV-Ab test is positive. Treatment period and end-of-treatment visit: Five hepatitis B markers (HBsAg, HBsAb, HBcAb, 
HBeAg, HBeAb) and HBV-DNA needs to be detected every two cycles of therapy (starting C3D1, C5D1, C7D1, etc.) for subjects with positive HBsAg or HBcAb at 
screening; HCV-RNA needs to be detected every two cycles of therapy (starting C3D1, C5D1, C7D1, etc.) for subjects with positive HCV-Ab at screening .   
[16] Hematology: including complete blood count and category (white blood cell, red blood cell, lymphocyte, monocyte, neutrophil, basophil, eosinophil), hemoglobin, platelet

on Day 15 of each cycle in Cycles 1-3, prior to administration only on Day 1 of each cycle in Cycles ≥ 4), at end-of-treatment visit and safety follow-up.  
[17] Urinalysis: white blood cell, red blood cell, urine protein should be included. If urine protein level ≥ 2＋ is detected, 24h urine protein quantification must be added. 
Urinalysis will be performed within 7 days prior to first dose, during the treatment period (prior to study drug administration on Day 1 of each cycle in Cycles 2-3 and on 
Day 15 of each cycle in Cycles 1-3, prior to administration only on Day 1 of each cycle in Cycles ≥ 4), at end-of-treatment visit and safety follow-up.  
[18] Fecal occult blood: If fecal occult blood test is positive during the trial, the result must be evaluated by investigators, and gastroscopy will be performed if necessary. 
Fecal occult blood will be performed within 14 days prior to first dose, on Day 1 of each cycle in Cycles ≥ 2 and at the end of study.  
[19] Blood biochemistry: hepatic function (ALT, AST, total bilirubin, ALP, γ-glutamyl transferase [GGT], direct bilirubin), renal function (blood urea nitrogen [BUN] or urea, 
creatinine), albumin, amylase (lipase must be detected additionally if amylase is abnormal and clinically significant), blood glucose, LDH should be included. Blood 
chemistry will be performed within 7 days prior to first dose, during the treatment period (prior to study drug administration on Day 1 of each cycle in Cycles 2-3 and on 
Day 15 of each cycle in Cycles 1-3, prior to administration only on Day 1 of each cycle in Cycles ≥ 4), at end-of-treatment visit and safety follow-up.  
[20] Blood electrolytes: potassium, sodium, calcium, phosphorus, magnesium, chlorine should be included. Blood electrolytes will be detected within 7 days prior to first dose, 
during the treatment period (prior to study drug administration on Day 1 of each cycle in Cycles 2-3 and on Day 15 of each cycle in Cycles 1-3, prior to administration 
only on Day 1 of each cycle in Cycles ≥ 4), at end-of-treatment visit and safety follow-up.

up.  
[24] Thyroid function: TSH, FT3 or TT3, FT4 should be included. Thyroid function will be performed within 14 days prior to the first dose, once every two cycles during the 
treatment period, at end-of-treatment visit and safety follow-up.  
[25] 12-lead ECG (following resting state/sitting still for at least 5 minutes): heart rate and QTc interval (calculated by Fridericia formula: QTcF = QT/(RR^0.33), RR is the 
normalized heart rate and is calculated as 60 divided by heart rate). If QTc interval is abnormal, QTc needs to be measured for three consecutive times at an interval of 
approximately two minutes apart;  
QTc needs to be re-tested if: 
  - at baseline: male > 450 ms, female > 470 ms, retest 2 times and take the mean value;  
  - after enrollment: same as baseline, or longer than the baseline average ≥ 30 ms.  
 Experimental arm: The 12-lead ECG will be performed within 14 days prior to first dose in screening period, 2.5 (±1) hours post dose at each of the following days: 
C1D1, C1D15, D1 of Cycles 2 and afterwards, and at end-of-treatment visit and safety follow-up. When the ECG collection day is coincident with the PK collection day, 
time matched ECG and PK samples (within 15 minutes apart, ECG collection first) will be collected. Control arm:14 days prior to first dose in screening period, C1D1, 
C1D15, D1 of Cycles 2 and afterwards, and at end-of-treatment visit and safety follow-up. 
[26] Echocardiography must include LVEF and can be scheduled at the investigator’s discretion during the study.  
[27] Blood HCG test: only for women of childbearing potential (WOCBP, any woman who has experienced menarche, has not undergone a hysterectomy, ligation of bilateral 
fallopian tubes or bilateral oophorectomy, and is not post-menopausal). (See definition of menopausal in Section 4.4.1) Blood HCG will be performed within 7 days prior 
to the first dose, at end-of-treatment visit and safety follow-up.  
[28] Collection of concomitant medication/therapy: collect concomitant medication/therapy information (drugs excluding solvents) from 28 days prior to the signing of the 
informed consent form to the end of safety follow-up: record drug names, drug dosage, route of administration, frequency of administration, purpose of administration, 
and date of start and end. After the safety follow-up period, only record medication/therapy that is used to manage the study drugs related AE/SAE. Please refer to 
Section 5.3 (Concomitant therapy) of the protocol for details. 
[29] Collection of AE: in accordance with NCI-CTCAE v4.03, AEs are observed and recorded from the signature of informed consent form, until 90 days after the last dose 
of SHR-1210, or 30 days after the last dose of anti-angiogenesis targeted therapy, whichever comes later. For specific AE collection periods, please refer to Section 8.3, 
Table of AE/SAE Collection Period. An AE/SAE will be followed up until it is resolved, returns to the baseline level or ≤ Grade 1, or reaches a stable state, or until other 
reasonable time points (e.g., loss of follow-up, death). Every effort should be made to ensure that the subject achieves the final outcome and definite causality assessment 
is obtained. 
[30] Tumor radiological evaluation: all the evaluable tumor lesions should be evaluated and recorded based on RECIST v1.1 (evaluated by investigator and BIRC), mRECIST 
(evaluated by BIRC only) and imRECIST (evaluated by investigator only). The baseline evaluation includes the enhanced CT/MRI scan of chest, abdomen, pelvis and 
sites of lesions, brain enhanced MRI or enhanced CT scan (to exclude intracranial metastasis). Thoracic plain CT scan + abdominal, pelvic and brain MRI can be 
performed in case of allergy to the contrast agent for enhanced CT; bone scan will be performed only when clinically indicated. Tumor radiological evaluation during 
treatment period will be performed once every 8 weeks (56±7 days) within the first 48 weeks from randomization and once every 12 weeks (84±7 days) thereafter and 
can be additionally performed when clinically indicated. When there is no clear disease progression, tumor evaluation should be continued regardless of discontinuation

of study treatment, unless death, withdrawal of informed consent, start of subsequent anticancer therapy or termination of study by the sponsor, whichever comes first; 
the evaluation includes the enhanced CT/MRI scan of chest, abdomen, pelvis and sites of lesions. Thoracic plain CT scan + abdominal and pelvic MRI can be performed 
in case of allergy to the contrast agent for enhanced CT; cranial CT/MRI and bone scan will be performed only when clinically indicated. The same radiological technique 
should be used in each subject throughout the study. Investigators must review the results prior to administration in the next cycle. After first documentation of response 
(CR or PR), confirmation of tumor response should occur at 4 weeks after the first response or at the next scheduled assessment time point. When a subject develops a 
disease progression as assessed by the investigator according to RECIST v1.1, the investigator is required to submit radiological data immediately to BIRC. If BIRC 
confirms non-disease progression according to RECIST v1.1, the subject should continue to receive study drug therapy and continue to perform tumor radiological 
assessment; if BIRC confirms disease progression according to RECIST v1.1, then the investigator needs to assess whether the subject still has clinical benefit, and if the 
subject is still considered to have clinical benefit and meets the criteria for continued treatment after progression of the disease (see Section 6.6 for details), the subject 
may continue to receive study medication and continue the efficacy assessment at the scheduled frequency. Tumor radiological assessment will continue until the 
occurrence of disease progression confirmed by BIRC according to RECIST v1.1 criteria or study treatment discontinuation, whichever occurs later. Before BIRC 
confirms the disease progression according to the RECIST v1.1 criteria or the treatment is discontinued, if the subject withdraws the informed consent, other anti-tumor 
treatment has begun (except for traditional Chinese medicine), or the subject dies, there is no need to continue the radiological evaluation. If the subject does not meet 
the above criteria for stop radiological assessment, the efficacy evaluation of the three efficacy evaluation criteria (RECIST v1.1, mRECIST, imRECIST) needs to 
continue even if the disease progression under certain efficacy evaluation criteria occurs. If there has not been any disease progression confirmed by a radiological 
examination when the subject is about to withdraw from the study, it is recommended that a radiological examination be performed in time before the withdrawal (if the 
time from the last radiological examination to the withdrawal is ≤ 4 weeks, additional radiological examination will not be required at the time of withdrawal). Detailed 
requirements for image collection will be described in image acquisition guideline. Disease progression will rely on the investigator’s confirmation per RECIST v1.1 
upon approval of protocol v6.0, and radiological data will not be submitted to BIRC anymore, tumor assessment evaluated by BIRC per mRECIST will not be performed 
afterwards. If the investigator confirms non-disease progression, the subject should continue on study treatment and tumor radiological evaluation as required; if the 
investigator confirms as disease progression, the subject may continue to receive study treatment after disease progression at the investigator’s discretion (see Section 
6.6). 
[31] Pre-dose sampling: only the blood sample in the experimental arm will be collected (including SHR-1210 combined with rivoceranib, SHR-1210 monotherapy or 
rivoceranib monotherapy) on Day 1 of Cycle 1-4 (C1D1, C2D1, C3D1 and C4D1) and once on Day 1 of every three cycles thereafter (The time point for sample collection 
will be within 0.5 hours prior to administration of rivoceranib); on 30 days (±7 days) after the last dose of SHR-1210. When SHR-1210 is interrupted for longer than 30 
days and is confirmed to be unable to resume, the subject is required to come for a site visit and collect blood sample. If the subject has started other anti-tumor therapy, 
it’s not necessary to collect the immunogenicity blood sample at 30 days (±7 days) after the last administration of SHR-1210. If SHR-1210 and/or rivoceranib is 
temporarily interrupted, pre-dose immunogenicity and PK sample will be collected on schedule. If only rivoceranib is interrupted, the time of sampling is 0.5 hours prior 
to SHR-1210 administration. On C1D1 approximately 6 mL venous blood will be collected for detection of the serum concentration and immunogenicity of SHR1210; 
On C2D1, C3D1 and C4D1 approximately 8mL venous blood will be collected, 6 mL will be used for detection of the serum concentration and immunogenicity of SHR-
1210, and 2 mL will be used for detection of plasma concentration of rivoceranib. The exact time of the previous administration of rivoceranib concentration will be 
collected (provided by the subject). Approximately 6 mL venous blood will be collected for detection of the serum concentration and immunogenicity of SHR1210 at the 
later time points (e.g., C7D1, C10D1 etc.). Pre-dose sampling will not be performed in the extension phase. [See BLOOD SAMPLE COLLECTION TABLE for details] 
[32] ECG blood sampling: ECG examination will be performed 2.5 hours (±1 hour) after the end of the rivoceranib administration, and blood will be collected within 15 
minutes after the ECG examination on the first day from Cycle 1 to Cycle 4. If the rivoceranib is temporarily interrupted, a blood sample within 15 minutes after ECG

will not be collected. 2 mL venous blood will be collected at each time point for the concentration of rivoceranib. ECG blood sampling will not be performed in the 
extension phase. [See BLOOD SAMPLE COLLECTION TABLE for details]. 
[33] Randomization: subjects will be randomized into either the experimental arm or control arm after their data are reviewed and determined to be in accordance with the 
inclusion/exclusion criteria, and the first dose should be given within 24 hours following randomization (on Day 1 of Cycle 1).  
[34] Distribution, verification and return of subject’s medication diary: in the experimental arm at D1 and D15 of each cycle, in the control arm, at D1 and D15 of Cycles 1-
3, and D1 for every cycle thereafter. On C1D1, only distribution is needed. At the end-of-treatment visit, distribution of diary is not needed but verification and return are 
required.  
[35] Subject’s self-evaluation results: all subjects will complete EORTC QLQ-C30 (version 3.0), EORTC QLQ-HCC18 and EQ-5D-5L questionnaires prior to administration 
of study drug and any study procedure at the clinical center, starting from C1D1 and on D1 of each cycle onward. In addition, all subjects are required to complete the 
questionnaires at the end-of-treatment visit and during the first safety follow-up visit. Before the subject leaves the site, the study staff should review all the questionnaires 
for completeness.

INTRODUCTION: BACKGROUND AND SCIENTIFIC 
RATIONALE 
1.1. 
Study Background 
1.1.1. 
Epidemiology and Current Treatment Status of Hepatocellular 
Carcinoma 
Primary Carcinoma of the Liver is referred to as liver carcinoma. Primary Carcinomas 
of the Liver mainly include three different pathological types of Hepatocellular 
Carcinoma (HCC), Intrahepatic Cholangiocarcinoma (ICC), and the mixed HCC-ICC, 
in which HCC accounts for 90% [1 ]. According to data from GLOBOCAN 2012, liver 
carcinoma is the sixth most common cancer, with about 782,500 new cases of liver 
carcinoma and 745,500 deaths worldwide annually, ranking it second in the cause of 
death amongst male tumors worldwide [2]. 
The majority of HCC cases (> 80%) occur in Eastern Asia and sub-Saharan Africa, with 
incidence rates of > 20 per 100,000 individuals, followed by Southern European 
countries, such as Spain, Italy and Greece, with an incidence of 10 to 20 cases per 
100,000 populations. HCC incidence is relatively lower in North America, South 
America, Northern Europe and Oceania (< 5 / 100,000) [3]. 
China is a high-risk area for liver carcinoma, with morbidity and death accounting for 
about 50% of the world [2]. In 2015, there were 466,100 new subjects with liver 
carcinoma, the fourth most common tumor, and 422,100 deaths in China. Liver 
carcinoma ranks the third as cause of death in China, and it ranks third in males (12.72%) 
and seventh in females (5.68%) [4]. 
The main risk factors for HCC are infection with HBV and hepatitis C virus (HCV), 
vinyl chloride, alcohol abuse, and nonalcoholic fatty liver; in addition, the rare causes 
include hereditary hemochromatosis, α-antitrypsin deficiency and autoimmune 
hepatitis [5]. HBV and HCV infection account for 80%~90% of total HCC cases 
worldwide. Chronic HBV infection is a major risk factor for HCC in most Asian regions 
except Japan[3],while chronic HCV infection is a major risk factor for HCC in Japan[6]. 
In China, up to 80% of HCC is hepatitis B virus (HBV)-related HCC [7]. A considerable 
proportion of subjects are already in advanced stage at diagnosis or cannot undergo 
surgery or local treatment due to underlying liver diseases such as combined cirrhosis. 
The different treatments of HCC are selected according to disease staging, which is 
mainly based on BCLC staging system, Child-Pugh liver function classification system 
and disease degree. About 30% of HCC cases are diagnosed at an early stage (that is, 
BCLC stage 0 or A), and the main treatments include surgical resection, ablation 
technique and liver transplantation. But the 5-year recurrence rate is still as high as 70% 
[8]. 
The recommended treatment for mid-stage HCC (BCLC stage B) is hepatic artery 
interventional therapy, that is, transcatheter arterial chemoembolization (TACE), but 
the application scope is limited due to concomitant disease and liver function damage, 
and the subject will eventually experience progression after treatment and is no longer 
suitable for further TACE treatment.

The treatment options available for advanced HCC (also known as BCLC stage C) are 
very limited, and sorafenib, an oral multi-target inhibitor, is the first targeted drug 
approved globally for HCC first-line systemic treatment. Recently, the FDA approved 
the second oral multi-kinase inhibitor lenvatinib for the first-line treatment of advanced 
HCC, which has not been widely used. In addition to the above two types of targeted 
therapy, the first-line standard of care of HCC also includes oxaliplatin-based 
chemotherapy, which is also used as the first-line treatment in some regions. 
1.1.2. 
Advances in the Treatment of Advanced Hepatocellular Carcinoma 
For advanced hepatocellular carcinoma, the available treatment options are very limited. 
Sorafenib is an oral multi-target inhibitor (VEGFR-1, -2, -3, PDGFR, c-KIT, etc.) that 
directly blocks the formation of neovascularization and inhibits tumor growth. It is the 
first FDA-approved targeted drug for HCC first-line systemic treatment. This approval 
was based on the positive results from the SHARP and ORIENTAL trials. The efficacy 
and safety of sorafenib and placebo were compared in the treatment of advanced HCC. 
The results showed that the survival and safety of subjects in the sorafenib group were 
significantly improved compared with those in the placebo group. 
The SHARP study was a randomized, phase 3 study in western populations, in which 
sorafenib increased progression free survival (PFS) (median: 5.5 months and 2.8 
months, respectively) by 73% and overall survival (OS) (median: 10.7 months and 7.9 
months, respectively) by 44% compared with placebo. ORIENTAL, another 
randomized phase 3 study conducted in Asian populations similar to the SHARP study 
in design, had the same results, increasing overall survival (OS) by 2.3 months (median 
OS: 6.5 months and 4.2 months, respectively)[9, 10]. 
In addition, the results of the phase 3 non-inferiority study on the efficacy and safety of 
lenvatinib (developed by Eisai) versus sorafenib in the first-line treatment of subjects 
with unresectable HCC (REFLECT trial [11]) showed, lenvatinib achieved the primary 
endpoint, demonstrating that the median OS with lenvatinib was non-inferior to that 
with sorafenib. Subjects treated with lenvatinib experienced a median OS of 13.6 
months compared to 12.3 months with sorafenib (Hazard Ratio [HR]: 0.92); In terms 
of secondary endpoints, lenvatinib seemed significantly superior to sorafenib in median 
PFS (7.4 months vs 3.7 months), median TTP (8.9 months vs 3.7 months) and ORR 
(24% vs 9%). In terms of safety, the incidence of adverse events (AE) was similar in 
the two groups. At the 2017 CSCO Annual Meeting, Professor Qin Shukui published 
the data analysis results of the Asian subgroup of the trial. A total of 288 subjects were 
enrolled. The lenvatinib and the sorafenib groups were compared in the median PFS 
(9.2 months vs 3.6 months), median TTP (11 months vs 3.7 months), and ORR (21.5% 
vs 8.3%), showing that lenvatinib was more effective for subgroups of subjects in 
China's mainland, Taiwan and Hong Kong and will become a new treatment option for 
subjects with unresectable advanced HCC worldwide. Based on REFLECT study, 
lenvatinib was approved by FDA as the second first-line treatment for advanced HCC 
following sorafenib. 
In addition to the two approved targeted therapies, Oxaliplatin-based chemotherapy is 
also the standard first-line treatment in some areas. The EACH study was a prospective, 
randomized, controlled phase 3 international clinical study of Oxaliplatin-containing 
FOLFOX4 chemotherapy and Doxorubicin for palliative chemotherapy in Asian

41 
subjects with advanced hepatocellular carcinoma who are not suitable for surgery or 
local treatment. The study had the largest number of enrolled subjects (371 cases) in the 
field of systemic chemotherapy for liver carcinoma, with Chinese subjects accounting 
for 75%. The study confirmed for the first time that compared with doxorubicin, the 
regimen with Oxaliplatin-containing FOLFOX4 prolonged the median OS of subjects 
with advanced liver cancer from 4.97 months to 6.40 months, reduced the risk of death 
by 20%, improved the median PFS (2.93 months vs. 1.77 months), reduced the risk of 
recurrence and metastasis, and significantly increased the ORR to 8.2%, meanwhile the 
adverse reactions could be tolerated [12]. 
Regorafenib, another oral multi-kinase inhibitor, was approved by the FDA in 2017 for 
the second-line treatment of subjects with HCC who received previous treatment with 
sorafenib, based on an international multicenter, placebo-controlled phase 3 clinical 
study (RESORCE study [13]). The data showed a significant improvement in OS in the 
Regorafenib group compared with placebo (median: 10.6 months vs. 7.8 months, 
HR=0.62, 95% CI 0.50-0.79, P<0.001), and the risk of death was reduced by 37%. The 
most common adverse reactions in the Regorafenib and placebo groups were pain (55% 
vs. 44%), hand-foot skin reaction/palmar-plantar erythrodysesthesia (51% vs. 7%), and 
weakness/fatigue (42% vs. 33%), diarrhea (41% vs. 15%), hypertension (31% vs. 6%), 
infection (31% vs. 18%), anorexia (31% vs. 15%). It is currently approved only for 
second-line treatment after the progression with sorafenib treatment; the registered 
clinical trials do not include subjects with post-chemotherapy progression/sorafenib 
intolerance, and there is no data on the efficacy of second-line and later-line therapies. 
At the same time, the incidence of treatment-related adverse events for Regorafenib is 
relatively high, limiting its clinical use. 
1.1.3. 
Development of PD-1/PD-L1 Monoclonal Antibody in Advanced Tumors 
Programmed cell death protein 1 (PD-1) is the first immune checkpoint molecule to be 
discovered, expressed in stimulated B cells, T cells, and myeloid cells. It is initially 
described as "a brake on the immune response" for its role in inhibiting the immune 
response by binding to the ligand PD-L1. PD-1/PD-L1 immunological checkpoint 
inhibitor is currently the most attractive tumor immunotherapy drug, which can regulate 
the anti-tumor activity of T lymphocytes by blocking PD-1/PD-L1 signaling pathway, 
and improve the subject's own immune response to tumor, thus achieving the purpose 
of killing tumor cells. 
Since 2014, the U.S. FDA has approved anti-PD-1 monoclonal antibodies, Bristol-
Myers Squibb's nivolumab and Merck's pembrolizumab, based on outstanding efficacy, 
for the treatment of subjects with advanced melanoma, non-small cell lung cancer, renal 
cell carcinoma, head and neck cancer, Hodgkin's lymphoma, urothelial carcinoma, 
MSI-H or dMMR malignant tumor, gastric cancer and gastroesophageal junction 
adenocarcinoma, and cervical cancer as well as subjects with hepatocellular carcinoma 
(HCC) who have received sorafenib, including advanced subjects who have failed 
standard treatment without effective treatment and are advanced to first- and second-
line treatments. In addition, due to the long-lasting efficacy and mild adverse reactions, 
hundreds of clinical trials on anti-PD-1 monoclonal antibodies (including monotherapy 
and combined therapy) have been conducted internationally for advanced solid tumor 
and haematological malignancy. The preliminary results of trials have shown greater 
efficacy and long-term survival compared with existing therapies. At the same time, in

terms of safety, drug-related toxicity was controllable, and the toxicity of Grade 3 and 
above was lower than that of traditional chemotherapy drugs [14 ]. 
1.1.3.1. PD-1/PD-L1 Monotherapy and Hepatocellular Carcinoma 
In advanced HCC, PD-1/PD-L1 antibody also showed significant initial efficacy: the 
Checkmate-040 study was a single-arm, open-label, dose escalation and expansion, 
phase I/II clinical study evaluating nivolumab monotherapy for advanced 
hepatocellular carcinoma: a total of 262 subjects (48 for dose escalation and 214 for 
expansion) were enrolled to evaluate the efficacy and safety of nivolumab. The results 
of this study indicate that the initial efficacy of nivolumab monotherapy for advanced 
hepatocellular carcinoma was significant. For the subjects with advanced HCC (N=154) 
who have been treated with sorafenib, the objective response rate (ORR) of nivolumab 
was 14.3%, and 91% of subjects had a duration of response (DoR) of 6 months or more. 
55% of subjects had a DoR of 12 months or more [15]. Based on this study, in September 
2017, the FDA approved nivolumab for subjects with advanced hepatocellular 
carcinoma (HCC) who had previously received sorafenib, marking the official entry 
into the era of immunotherapy for HCC. 
In addition, the KEYNOTE 224 study also confirmed the significant efficacy of PD-1 
monoclonal antibody in HCC. This study was a one-arm, open-label, phase II clinical 
trial of pembrolizumab monotherapy for subjects with advanced HCC who had failed 
or were intolerant to sorafenib alone. A total of 104 subjects with advanced HCC were 
enrolled in the study. The results showed that the ORR of pembrolizumab was 17%, the 
DCR was 62%, the median PFS was 4.9 months, and the median OS was 12.9 months 
[16]. Based on this study, in November 2018, the FDA approved pembrolizumab 
indicated for the treatment of subjects with advanced HCC who have previously failed 
sorafenib treatment. Because of the prominent efficacy of PD - 1 antibodies in liver 
carcinoma, the domestic and foreign companies have carried out a number of 
randomized, controlled phase 3 studies of PD-1 antibody monotherapy for advanced 
hepatocellular carcinoma. 
Despite the unprecedented success of PD-1/PD-L1 antibodies, it should not be 
overlooked that nearly 50% of solid tumor subjects do not benefit from this therapy. 
Taking advanced hepatocellular carcinoma accompanied with HBV infection as an 
example (about 90% of subjects with hepatocellular carcinoma in China are 
accompanied by HBV infection), the ORR of nivolumab was only 14%, and the DCR 
was only 55%. Nearly half of the subjects developed disease progression after 8 weeks 
of treatment. How to optimize the efficacy of anti-PD-1 antibody in advanced HCC on 
the basis of monotherapy effectiveness has become an urgent problem to be solved. 
1.1.3.2. PD-1/PD-L1 Combined with Anti-angiogenic Targeted Drugs 
At present, there are two methods for improving the efficacy of PD-1/PD-L1 
immunotherapy. Firstly, molecular markers that predict efficacy have been explored. In 
this direction, the therapeutic effect of PD-1/PD-L1 is improved by detecting and 
enriching subjects with molecular markers such as the expression level of PD-L1 in 
tumor tissue, the level of tumor mutational burden (TMB), high microsatellite 
instability (MSI-H) and dMMR. Secondly, a suitable combination regimen for 
immunological combination therapy are being sought. At present, a large number of

43 
clinical studies have been carried out on the combination of PD-1/PD-L1 inhibitors with 
other immunological checkpoint inhibitors, traditional chemotherapeutic drugs or 
targeted anti-tumor drugs. 
Among them, PD-1/PD-L1 inhibitors combined with anti-angiogenic targeted drugs 
have a significant synergistic effect on efficacy. Currently, the FDA has granted 
breakthrough therapy designation for the multiple PD-1/PD-L1 inhibitors combined 
with anti-angiogenic targeted drugs. In a phase Ib clinical study of pembrolizumab 
combined with Axitinib for the treatment of advanced renal cell carcinoma, a total of 
52 subjects with advanced renal cell carcinoma who had not received systemic 
treatment were recruited in the study. The optimal dose of the combination was taken 
as the primary endpoint, and the efficacy endpoints such as ORR, DoR, and PFS were 
also assessed. The observation results of tolerance showed that the combination of 
Axitinib standard dose (5 mg, BID) and pembrolizumab, 2 mg/kg Q3W was well 
tolerated. The efficacy results showed that the anti-tumor effect of combined therapy 
was far superior to that of Axitinib or anti-PD-1 monotherapy, and ORR reached 73%, 
among which 8% achieved complete response. More than 90% of subjects showed 
tumor shrinkage and mPFS was over 20 months, far exceeding Axitinib monotherapy 
for control of disease progression (mPFS = 10-15 months). While there are still no data 
on pembrolizumab monotherapy for renal cell carcinoma, the synergistic effect of 
Axitinib and pembrolizumab in the treatment of renal cell carcinoma is superior to that 
of nivolumab (ORR = 13%) and atezolizumab (untreated: ORR = 25%, mPFS = 6 
months; treated: ORR = 15%, mPFS = 6 months) monotherapy[17]. In addition, based 
on excellent efficacy data, pembrolizumab combined with lenvatinib in the treatment 
of advanced renal cell carcinoma and advanced endometrial cancer, as well as PD-L1 
monoclonal antibody Avelumab combined with Axitinib in the treatment of advanced 
renal cell carcinoma has been granted breakthrough therapy designation by the FDA. 
In addition to renal cell carcinoma, combinations of anti-PD-1/PD-L1 inhibitors and 
VEGFR inhibitors have shown good efficacy in many solid tumors such as non-small 
cell lung cancer, hepatocellular carcinoma, and endometrioid carcinoma. A number of 
phase 3 studies are ongoing. 
In the combination therapy of advanced hepatocellular carcinoma, anti-angiogenic 
targeted drugs have also achieved breakthroughs in combination with PD-1/PD-L1 
antibodies. Several studies have confirmed that PD-1/PD-L1 antibodies and anti-
angiogenic targeted drugs, including small molecule VEGFR inhibitors and 
VEGF/VEGFR antibodies, are safe and well tolerated, and can achieve synergistic 
effects. 
In 2019, the updated efficacy of atezolizumab in combination with bevacizumab in the 
treatment of advanced hepatocellular carcinoma was reported in ESMO. This study was 
performed with atezolizumab in combination with bevacizumab in subjects with 
advanced hepatocellular carcinoma who had not received systemic therapy. Of the 104 
evaluable cases, a total of 37 cases of response were observed, with an confirmed ORR 
of 36%, DCR was 71%, mPFS was 7.3 months (95%CI: 5.4, 9.9), mOS was 17.1months 
(95%CI:13.8, NE) [18]. A randomized, controlled phase 3 clinical study of atezolizumab 
in combination with bevacizumab versus sorafenib in the treatment of unresectable 
locally advanced or metastatic hepatocellular carcinoma had been initiated since 2018 
(IMbrave150, NCT03434379), of which primary endpoints were OS and BIRC

evaluated PFS per RECIST v1.1, and the positive result was reported during the ESMO-
Asia 2019. A total of 501 advanced HCC subjects were randomized at 2:1 to receive 
atezolizumab combined with bevacizumab (336 subjects) or sorafenib (165 subjects). 
The mOS in the experimental arm has not reached, the mOS in the control arm was 13.2 
months, HR=0.58. The mPFS was 6.8 months (95%CI: 5.7, 8.3) and 4.3 months 
(95%CI: 4.0, 5.6) in experimental arm and control arm respectively [19]. The Chinese 
subgroup data was released in the following EASL 2020, a total of 194 Chinese subjects 
(137 of them were from the study of IMbrave 150, and 57 of them were from the 
extended enrollment in China；experimental arm 133 subjects, control arm 61 subjects) 
were enrolled in this study. The mOS in the experimental arm has not reached, the 
control arm mOS was 11.4 months, HR=0.44. The mPFS was 5.7 months (95%CI: 4.2, 
8.3) and 3.2 months (95%CI: 2.6, 4.8) in experimental arm and control arm respectively, 
HR=0.60 [20].  
In another phase Ib study of pembrolizumab combined with lenvatinib for unresectable 
hepatocellular carcinoma which was reported during ESMO 2019, all 67 subjects with 
hepatocellular carcinoma who were enrolled in efficacy expansion stage of the study 
had never received sorafenib treatment. Based on IRC assessment according to RECIST 
v1.1, the ORR and DCR was 32.8% (95% CI: 21.8, 45.4) and 85.1% (95% CI: 74.3, 
92.6), mPFS was 9.5 months (95%CI: 5.6, 11.8) and mOS was 20.4 months (95%CI: 
11.0, NE) [21]. Based on above phase Ib data, a phase III, randomized, double-blind 
study of pembrolizumab combined with lenvatinib versus lenvatinib as the first-line 
treatment for advanced HCC is ongoing. 
The preliminary results of an exploratory clinical study of SHR-1210 combined with 
the VEGFR inhibitor rivoceranib in hepatocellular carcinoma and gastric cancer were 
also published in 2018. For the dose group of SHR-1210 200 mg, Q2W combined with 
rivoceranib 125 mg, 250 mg or 500 mg, QD. Total 18 subjects with HCC enrolled, 16 
were evaluable (all HBV-positive, 15 of which failed after sorafenib), 8 of which were 
evaluated as disease remission, the objective response rate (ORR) was 50% (95%CI: 
24.7, 75.4), DCR was 93.8% (95% CI: 69.8, 99.8), median time to response was 3.4 
months (range, 1.4, 9.7), mPFS was 5.8 months (95% CI: 2.6, NR), and the initial effect 
was significant[22]. 
It can be seen that sorafenib is still a widely recognized first-line treatment for advanced 
hepatocellular carcinoma after 10 years on the market. However, the overall efficacy of 
sorafenib for hepatocellular carcinoma is relatively poor. A number of studies have 
confirmed that the ORR of sorafenib in the treatment of advanced liver carcinoma is 
<10%, with mOS <10 months [ 9, 10, 11]. At present, the first-line systemic treatment of 
Chinese subjects with advanced HCC is mainly based on sorafenib and Oxaliplatin-
containing systemic chemotherapy, but the ORR is low and the survival benefit is 
limited [10, 12]. Another first-line treatment of lenvatinib has not been widely used yet. 
Therefore, there is an urgent need to develop a new and effective treatment regimen for 
advanced HCC. 
Multiple studies of immunological checkpoint inhibitors, such as PD-1/PD-L1 
monoclonal antibody, have shown good efficacy in the treatment of HCC. Compared 
with other systemic therapies, they have the features of high ORR, long response time 
and prolonged survival [15-16].

Therefore, this study is a registration study of PD-1 monoclonal antibody SHR-1210 
combined with rivoceranib in the treatment of advanced primary hepatocellular 
carcinoma and hopes to provide guidance and experience for the new combination 
therapy of immunotherapy combined with targeted therapy in the future, so as to 
improve the anti-tumor effect of monotherapy, minimize toxic side effects, and 
ultimately bring better survival benefits to the majority of subjects.

[English name]: Camrelizumab 
[Drug number]: SHR-1210 
[Molecular weight]: about 146.3 kDa 
1.2.1.2. Pharmacological Class and Mechanism of Action 
Programmed death-1 (PD-1) is a protein receptor expressed on the T cell surface that 
was discovered in 1992 [23] and involved in the process of apoptosis. PD-1 belongs to 
the CD28 family, possessing 23% amino acid homology with cytotoxic T lymphocyte 
antigen 4 (CTLA-4), but its expression is mainly on activated T cells, B cells and 
myeloid cells, which is different from that of CTLA-4. PD-1 has two ligands, PD-L1 
and PD-L2, respectively. PD-L1 is mainly expressed on T cells, B cells, macrophages 
and dendritic cells, and can be up-regulated on activated cells [24]. The expression of 
PD-L2 is relatively limited, mainly on antigen-presenting cells, such as activated 
macrophages and dendritic cells. The humanized anti-PD-1 monoclonal antibody 
specifically binds to PD-1 and blocks the interaction of PD-1 with its ligand, allowing 
T cells to recover immune response against the tumor cells. 
1.2.1.3. Pharmacodynamic Studies 
1) Affinity of antibody 
The affinity of SHR-1210 for human, mouse, and cynomolgus and rhesus monkey PD-
1 was determined using Surface Plasmon Resonance (SPR) technology. The Kd values 
for human and cynomolgus and rhesus monkey PD-1 are shown in Table 1. The binding 
affinity of SHR-1210 to mouse PD-1 was also measured; however, no binding was 
detected at the highest concentration tested (400 nM).

Binding of SHR-1210 to human and cynomolgus monkey neonatal Fc receptor (FcRn) 
was investigated. SHR-1210 binds to human and cynomolgus monkey FcRns with 
similar Kd values. 
The binding of SHR-1210 to different FcγR proteins was also evaluated using SPR 
technology. The data indicate that the binding of SHR-1210 to different FcγR proteins 
is consistent with an IgG4 antibody isotype. 
From the detection of the binding affinity, the affinity of SHR-1210 to antigen (human 
PD-1) was 3.0 nM, which was comparable to that of control antibodies nivolumab and 
MK3475 (pembrolizumab). The results are shown in Table 2.

2) Experiment on antibody SHR-1210 blocking the binding of PD-1/PD-L1 
The experimental results (see Figure 1 and Figure 2) showed that the antibody SHR-
1210, nivolumab and pembrolizumab were comparable in blocking the binding of PD-
1 / PD-L1 in vitro. The blocking activity of the antibodies SHR-1210, nivolumab and 
pembrolizumab was 0.70 nM / 0.79 nM, 0.79 nM / 0.77 nM, respectively.

1.2.1.4. Toxicology Studies 
Eight cynomolgus monkeys (half males and half females) were randomly divided into 
two groups in a pre-clinical study of acute toxicity. SHR-1210 was intravenously 
injected at 200, 400 and 800 mg / kg for animals in Group 2 every other day in a dose 
escalation manner. No changes in clinical signs, weight, food consumption and 
coagulation associated with SHR-1210 were observed. When dose ≥ 200 mg / kg, 
lymphopenia was observed in male and female animals; when dose ≥ 400 mg / kg, 
increased serum globulin and decreased albumin were observed in male and female 
animals. The above changes were small, so it was not considered as harmful effects. 
The maximum tolerated dose (MTD) of SHR-1210 is ≥ 800 mg/kg. 
In the completed pre-clinical study of chronic toxicity in cynomolgus monkeys, male 
and female cynomolgus monkeys SHR-1210 was well tolerated when intravenously 
injected at 20, 50 and 100 mg / kg once weekly for 4 weeks (5 times in total) or 26 
weeks (26 times in total). No changes in clinical signs associated with SHR-1210 were 
observed, including injection site irritation, body weight, food consumption, body 
temperature, 12-lead ECG, blood pressure, heart rate and respiratory parameters; No 
changes in B and T lymphocyte typing, cytokine, immunoglobulin and complement 
parameters were observed; No changes in organ weights, gross lesions and 
histopathological changes associated with SHR-1210 were observed.

with incidence of ≥ 2% mainly included anemia (6.2%), pulmonary infection (5.8%), 
elevated conjugated bilirubin (3.9%), decreased serum sodium concentration (3.5%), 
death 
(3.1%), 
elevated 
asparagine 
transaminase 
(2.7%), 
elevated 
alanine 
aminotransferase (2.3%), and elevated blood bilirubin (2.3%). 
Among 258 subjects, AEs of Grade 3 or above with an incidence of ≥ 2% mainly 
included anemia (7.0%), pulmonary infection (6.6%), decreased serum sodium 
concentration (4.3%), and elevated conjugated bilirubin (3.9%), progressive tumor 
(3.5%), death (3.1%), elevated asparagine transaminase (2.7%), elevated alanine 
aminotransferase (2.3%), elevated blood bilirubin (2.3%). 
Overall, the AEs of SHR-1210 were similar to those of the already marketed same kind 
of drugs in subjects with advanced solid tumors except for reactive cutaneous capillary 
endothelial proliferation (RCCEP). Most of the RCCEP occurred within 1-2 months 
after the start of the study drug. The early ones could appear several days after the 
administration, and the late ones could appear about 5 months after the administration, 
mainly in the trunk or limbs. The vast majority (99.5%) were CTCAE 1-2, and only one 
subject reported Grade 3. The subject was rated as Grade 3 AE due to hospitalization 
from surgical resection, and no subjects discontinued medication due to this AE. A small 
number of subjects with bleeding symptoms received local symptomatic treatment. The 
symptoms usually resolved after stopping SHR-1210 treatment. Overall, SHR-1210 has 
good safety and tolerability. 
1.2.2.2. Preliminary Results of SHR-1210 Monotherapy for HCC Study 
The study was a single-arm study of SHR-1210 in subjects with advanced HCC who 
had undergone systemic therapy (NCT02989922). SHR-1210 was administered at a 
dose of 3 mg/kg once every 2 weeks or every 3 weeks. The enrollment of this study has 
been completed, the data was published in Lancet Oncology [25]. As of November16, 
2018 (data cut-off date), 12 months after last subject received first dose, 217 subjects 
received at least one dose of SHR-1210. 
Of 217 subjects treated, 206 (94.9%) were BCLC stage C subjects; all subjects received 
at least ≥ 1 line systemic therapies, 49 (23%) subjects underwent at least ≥ 2 line 
systemic therapies before enrollment; 177 (82%) subjects had extrahepatic metastasis 
at baseline; 171 (79%) subjects had a baseline ECOG-PS score of 1; 111(51%) subjects 
had baseline AFP ≥ 400 ng/mL, 181 (83%) subjects had HBV infection. 217 subjects 
met the definition of the full analysis set and were included in the full analysis set.

assessment data (as of November 16, 2018, RECIST Version 1.1), overall ORR was 
14.7% (95% CI: 10.3, 20.2). The ORR of the Q2W group was 11.9% (95% CI: 6.5, 
19.5), and the ORR of the Q3W group was 17.6% (95% CI: 10.9, 26.1).  
The 6-month OS rate was 74.7% (95% CI: 68.3, 79.9). The Q2W group was 75.9% (95% 
CI: 66.6, 82.9), and the Q3W group was 73.0% (95% CI: 63.6, 80.4). 
As of data cut-off of November16, 2018, the median follow-up was 12.5 months and 
the observed median OS was 13.8 months (95% CI: 11.5, 16.6).  
Safety results: the category and frequency of common AE were similar to those in phase 
I clinical studies of this study drug. The most common drug-related AEs (incidence of 
any group ≥ 10%) were reactive cutaneous capillary endothelial proliferation, elevated 
transaminases, proteinuria, hyperbilirubinemia, hypothyroidism, thrombocytopenia, 
leukopenia and fatigue. 22% of subjects had at least one drug-related AE of Grade 3 or 
Grade 4. 4% of subjects discontinued experimental drugs due to drug-related AE. At 
least one drug-related SAE occurred in 11% of subjects.  
In this study, 145 (67%) subjects developed reactive capillary endothelial proliferation 
(all in skin, of which three were accompanied in oral mucosa, two cases nasal mucosa, 
two cases palpebral conjunctiva). Except one case was grade 3, others reactive capillary 
endothelial proliferation cases were grade 1-2, mild, self-limiting and clinically 
manageable.  
Clinically significant results in laboratory tests were reported as AE, with no other 
indicators of special attention. Vital signs were stable and there were no extreme values.

brochure. 
1.2.3. 
Progress in Clinical Research of Rivoceranib Monotherapy for Advanced 
HCC 
This clinical study also involved rivoceranib mesylate tablets (trade name: Aitan), 
which was launched in 2014 by Jiangsu Hengrui Pharmaceuticals Co., Ltd. Rivoceranib 
is a small molecule targeted drug, a vascular endothelial growth factor receptor 
(VEGFR) tyrosine kinase inhibitor, which exerts anti-angiogenic effects on malignant 
tumors mainly through inhibiting VEGFR. Preclinical studies show that its anti-tumor 
effect is superior to similar drugs. In 2014, rivoceranib was approved in China for 
treatment of progression or recurrence of advanced gastric adenocarcinoma or 
adenocarcinoma of gastroesophageal junction after previous use of at least two systemic 
chemotherapies. 
HCC is also a typical tumor with an abundant blood supply, and its occurrence, 
development, metastasis and invasion are closely related to angiogenesis. In 2010-2013, 
the 81st hospital of the Chinese People’s Liberation Army led a randomized, open-label, 
multicenter phase II clinical trial of rivoceranib mesylate tablets in the treatment of 
advanced hepatocellular carcinoma (NCT01192971) [26], and a total of 121 subjects 
received the medication. In the full analysis set, the median time to progression (mTTP) 
and median overall survival (mOS) were 4.21 months and 9.71 months in the 850 mg 
group, and the mTTP and mOS in the 750 mg group were 3.32 months and 9.82 months.

There were no statistically significant differences in mTTP and mOS between the 850 
mg and 750 mg groups. The incidence of adverse reactions was 95.71% and 90.20% in 
850 mg and 750 mg groups, respectively; the incidence of severe adverse reactions was 
58.57% and 58.82%, respectively, the difference was not statistically significant. 
Therefore, a well-tolerated 750 mg is recommended as the dose for the phase 3 clinical 
study. The recommended dosing regimen is 750 mg, PO, QD; 28 days is a cycle 
(excluding the time for discontinuance), and continuous administration until the disease 
progression or an intolerable adverse reaction. If a Grade 3/4 hematologic or non-
hematologic adverse reaction occurs, it is recommended to suspend the medication (not 
more than 2 weeks) or to reduce the dose to 500 mg or 250 mg. 
A randomized (2:1), open-label, placebo-controlled, multicenter, phase 3 clinical trial 
of rivoceranib (NCT02329860) is currently ongoing to investigate the efficacy and 
safety of rivoceranib in the second-line treatment of advanced HCC. The trial recruited 
subjects with advanced HCC who have failed, relapsed or are intolerant to side effects 
with sorafenib or systemic chemotherapy. As of December 2017, 400 subjects have 
been enrolled. Adverse events that have been observed include proteinuria, elevated 
blood pressure, thrombocytopenia, hand-foot syndrome, and elevated total bilirubin. 
For more information on the rivoceranib mesylate tablets, please refer to the package 
insert of the rivoceranib mesylate tablets and the investigator's brochure provided by 
the sponsor. 
Based on the above-mentioned large-scale data from these randomized controlled 
clinical studies, the main adverse reactions are hand and foot skin reactions, 
hypertension, 
elevated 
transaminases, 
elevated 
bilirubin, 
leukopenia, 
thrombocytopenia, diarrhea, esophagitis, nausea, and fatigue, most of which are mild 
to moderate reactions.

Preliminary Data of SHR-1210 Combined with Rivoceranib 
1.2.4.1. Potential Mechanisms of Combination Administration and Preclinical 
Studies 
The VEGFR signaling pathway plays an important role in mediating tumor immune 
escape, and inhibition of this pathway may enhance the activation of tumor immunity 
by PD-1 antibodies. 
Preclinical data from Jiangsu Hengrui Pharmaceuticals Co., Ltd. suggested that SHR-
1210 combined with rivoceranib could significantly reduce the regulatory T cell (Treg) 
levels in peripheral blood and increase the ratio of effector T cell (Teff) to Treg. 
The results of animal studies showed that SHR-1210 combined with rivoceranib 
significantly enhanced the tumor growth inhibition of SHR-1210 without increasing 
significant toxicity (no significant change in animal body weight):

Preclinical findings suggest that the use of SHR-1210 in combination with rivoceranib 
may increase the ORR of the tumor while preserving the efficacy and persistence of 
immunotherapy. 
1.2.4.2. Exploration of Combination Administration in Preliminary Clinical 
Studies 
Since October 2016, Jiangsu Hengrui Pharmaceuticals Co., Ltd. has served as a funder 
or sponsor to conduct a number of clinical trials of SHR-1210 combined with 
rivoceranib mesylate, involving a variety of solid tumors such as advanced 
hepatocellular 
carcinoma, 
advanced 
lung 
cancer, 
advanced 
intrahepatic 
cholangiocarcinoma, advanced gastric adenocarcinoma and advanced triple-negative 
breast cancer. These studies explored the safety and tolerance of SHR-1210 combined 
with rivoceranib mesylate and the initial efficacy against a variety of tumors. 
Preliminary results confirm: for SHR-1210 200 mg fixed dose, once every two weeks 
(Q2W) combined with rivoceranib mesylate 250 mg/d, continuous oral dose level is 
tolerable, while the combination regimen for a variety of tumors have shown a 
significant efficacy, significantly increasing the proportion of subjects benefiting from 
treatment.

1.2.4.3. Selection of Doses for Combined Therapy 
The dose-response relationship analysis was performed on the safety and efficacy data 
of three phase I studies of SHR-1210-101, SHR-1210-102 and SHR-1210-103. This 
analysis defines SHR-1210 (ORR+DCR)/2 as the efficacy index and (number of 
subjects with at least one drug-related AE + skin and subcutaneous tissue disease)/2 as 
the safety index. Figure 4 shows that the efficacy index reaches a steady state at a dose 
of 200 mg Q2W; the safety index increases with the dose. The optimal benefit dose for 
subjects can be defined as the dose with the least severe side effects in the case of 
maximum efficacy. The efficacy index and safety index show that 200 mg Q2W is the 
best benefit dose for subjects.

Relationship of Efficacy and Safety Indexes with Doses 
In one exploratory clinical study on SHR-1210 combined with rivoceranib mesylate in 
treatment of advanced hepatocellular carcinoma and gastric cancer [20.] (NCT02942329), 
the tolerability of SHR-1210 200 mg at the fixed dose of once every two weeks (Q2W) 
combined with rivoceranib mesylate 125 mg/d, 250 mg/d or 500 mg/d for continuous 
administration was observed, and the results showed that rivoceranib 125 mg QD po 
combined with SHR-1210 200 mg Q2W was well tolerated without dose-limiting 
toxicity (DLT); 3/5 subjects given rivoceranib 500 mg QD po combined with SHR-
1210 200 mg Q2W had Grade 3 immune-related pneumonia that could not be tolerated 
during observation of tolerability; 1/5 subject given rivoceranib 250 mg QD po 
combined with SHR-1210 200 mg Q2W had Grade 3 elevated lipase with no clinical 
symptoms during observation of tolerability, the symptoms disappeared after 
symptomatic treatment, see Table 4 for the detail. 
The observation of tolerability showed that rivoceranib 250mg/d po continuously 
combined with SHR-1210 200 mg, Q2W was tolerable in treatment of advanced 
hepatocellular carcinoma, gastric cancer and gastroesophageal junction carcinoma. 
This dose level was selected for efficacy extension in the study subsequently.

tolerability showed that, in the 12 subjects participating in the tolerability observation 
of SHR-1210 200 mg fixed dose once every two weeks (Q2W) combined with 
rivoceranib mesylate 250 mg qd, the clinically significant toxicity was observed in only 
2 subjects during observation of tolerability, which was 1 case of dose interruption of 
rivoceranib for > 7 days caused by increased hydrothorax (suspected pleural fistula) 
and 1 case of dose interruption of rivoceranib for > 7 days caused by anorexia with 
weakness. The incidence of clinically significant toxicity was 16.7% (2/12), the dose 
level was tolerable; in the subsequent observation of the tolerability of SHR-1210 200 
mg fixed dose once every two weeks (Q2W) combined with rivoceranib mesylate 375 
mg QD, a total of 4/12 evaluable subjects had Grade 3 rash during observation of 
tolerability, the incidence of clinically significant toxicity was 33.3%(4/12), the 
proportion of subjects with significant toxicity reached 1/3, and the dose level was 
intolerable.

above studies, it has been decided that the clinically observed tolerable dose will be 
selected in the upcoming phase 3 studies on SHR-1210 combined with rivoceranib 
mesylate as the first-line therapy for advanced hepatocellular carcinoma: SHR-1210 
200 mg, Q2W combined with rivoceranib 250 mg QD po continuously as combined 
therapy dose.  
1.2.4.4. Preliminary Efficacy of Combined Therapy 
In the exploratory clinical study on SHR-1210 combined with rivoceranib mesylate for 
treatment of advanced hepatocellular carcinoma and gastric cancer, it was found 
through the efficacy extension in SHR-1210 200 mg, Q2W combined with rivoceranib 
250 mg QD continuously that this combined regimen had significant efficacy in 
advanced hepatocellular carcinoma: in the 14 subjects with liver cancer enrolled at this 
dose level, there were 13 evaluable subjects (all positive HBV, including 12 subjects 
with failure of sorafenib), 7 subjects were evaluated as disease remission, the objective 
response rate (ORR) reached 53.8% and the remission was durable, no progression of 
disease was seen in 6 subjects with disease remission after treatment for 18-72 weeks; 
PFS rates of 6-month and 9-month were 51.3% (95% CI: 21.4, 74.9) and 41.0% (95% 
CI:13.8, 66.9) respectively, and the median PFS was 7.2 months (95% CI: 4.1,NR), the 
preliminary efficacy was significant[22]. 
 
Figure 5. 
The Best Response of SHR-1210 Combined with Rivoceranib in 
Advanced Hepatocellular Carcinoma and Change in the Diameter of Target 
Lesions After Administration 
Above preliminary data demonstrated that compared with current therapeutic regimen, 
such as sorafenib, the ORR was <10%; while the ORR of Nivolumab treatment for 
advanced HCC after sorafenib exposure was 14.3%, DCR was 55%. Per above 
preliminary results, SHR-1210 combined with rivoceranib mesylate looks having an 
obvious advantage in treatment of advanced HCC.  
In summary, under the selected dose, SHR-1210 combined with rivoceranib had a good 
tolerability and significant preliminary efficacy observed in advanced hepatocellular 
carcinoma. The randomized, controlled study of SHR-1210 combined with rivoceranib 
versus sorafenib in uncurable HCC is expected to achieve positive outcome and provide 
a more effective therapeutic option for vast subjects with HCC.

1.2.5. 
Selection Rationale of Control Arm 
Sorafenib was approved by the FDA as a targeted therapy for HCC in 2007. Sorafenib 
is an oral multitarget inhibitor (VEGFR-1, -2, -3, PDGFR and c-KIT) that blocks tumor 
neovascularization and inhibits tumor growth directly. The approval of sorafenib is 
based on the active results from SHARP and ORIENTAL trials. SHARP trial is a phase 
3 trial conducted mainly in European and American subjects to compare the efficacy 
and safety of sorafenib versus placebo in treatment of advanced HCC. The results 
showed a significantly improved survival in sorafenib group compared with placebo 
group. The ORIENTAL trial in parallel to SHARP trial enrolled subjects with advanced 
HCC in Asian-Pacific region using the same design. The results showed a similar 
significant improvement in survival with sorafenib in Asian subjects. A total of 3,371 
subjects with unresectable advanced HCC were enrolled in GIDEON study intended to 
acquire the clinical safety data of sorafenib. The results showed an OS of 13.6, 5.2 and 
2.6 months, and median TTP of 4.7, 4.4 and 3.6 months in subjects with CHILD Grade 
A, B and C, indicating better benefit for earlier treatment with sorafenib.

care therapy for advanced HCC and thus has been selected for comparison of first-line 
treatment of participants assigned to the control arm.  
1.3. 
Potential Risks and Benefits 
As described above, current therapies have limited efficacy in advanced hepatocellular 
carcinoma, only less than 10% of subjects can achieve response from the 1st-line 
therapy with sorafenib. Lenvatinib was approved by the FDA in August 2018 as the 
first-line therapy for subjects with unresectable hepatocellular carcinoma and has not 
been widely used yet. The PD-1 antibodies nivolumab and pembrolizumab that were 
approved in recent years have achieved significant response in the exploratory 
application in HCC. For example, for subjects with advanced hepatocellular carcinoma 
who have received sorafenib for treatment, the ORR is 14.3% in those who have 
received PD-1 antibody (nivolumab) and is superior to current therapeutic approaches. 
In particular, when PD-1/PD-L1 antibody is combined with anti-angiogenesis targeted 
drug, efficacy is enhanced; moreover, the combined therapy is safe, well tolerated and 
can achieve a synergistic effect. SHR-1210 is one humanized PD-1 antibody that is 
independently researched and developed by Jiangsu Hengrui Pharmaceuticals Co., Ltd. 
The preclinical data in animal experiments showed a similar affinity and antitumor 
effect with nivolumab and pembrolizumab. At the same time, SHR-1210 combined with 
rivoceranib has achieved an encouraging preliminary result in treatment of advanced

hepatocellular carcinoma. Participation in the phase 3 study to receive the study drug 
may provide clinical benefit to subjects with advanced HCC and offer a useful 
therapeutic option for them.  
1.3.1. 
Known Potential Risks 
In the previous clinical studies for multiple solid tumors (including HCC) and 
hematological tumors, the most common (≥ 10%) adverse reactions induced by SHR-
1210 included: reactive capillary endothelial proliferation (RCEP), various rashes, 
immune endocrine dysfunction such as hyperthyroidism/hypothyroidism, fatigue, 
elevated transaminase, most of which were Grade 1-2 and could be recovered after 
symptomatic treatment or dose interruption, had relatively small effect on subject’s 
physiological function and quality of life, and did not hinder continuation of the study 
treatment. RCCEP is a unique skin reaction of SHR-1210. Although with a relatively 
high incidence in the SHR-1210 monotherapy, RCEP was relatively mild in severity 
and clinically tolerable, and could be recovered after discontinuation of the drug. 
Moreover, in the treatment of SHR-1210 combined with rivoceranib, the incidence of 
RCEP was significantly reduced, which may be related to the anti-angiogenic effect of 
rivoceranib. The most common serious adverse reactions of SHR-1210 include 
pneumonitis, abnormal liver function, lung infection and thrombocytopenia. Various 
immune-related adverse reactions are potential risks of SHR-1210, which are class 
effects of PD-1 antibody preparations and include pneumonitis, hepatitis, thyroiditis, 
myocarditis, enteritis, severe cutaneous adverse reactions (including Stevens–Johnson 
syndrome (SJS), toxic epidermal necrolysis (TEN)) etc. Symptomatic treatment will be 
given in accordance with EMSO/NCCN guideline on management of immunotoxicity 
and can ensure the safety of subjects during the trial. Please refer to the investigator’s 
brochure for more details on adverse drug reactions associated with SHR-1210. 
Rivoceranib mesylate tablets were approved by the Chinese drug regulatory authorities 
for the treatment of advanced gastric cancer in October 2014. The recommended initial 
dose is 850 mg, orally, once daily. The most common (≥ 10%) adverse reactions of 
rivoceranib (850 mg QD) are hand and foot skin reactions, hypertension, elevated 
transaminases, elevated bilirubin, elevated alkaline phosphatase, elevated γ-glutamyl 
transferase, proteinuria, diarrhea, leukopenia, thrombocytopenia, anemia, fatigue, etc., 
most of which are mild to moderate reactions and can be recovered or improved after 
the drug is temporarily discontinued and treatment is given. In addition, the use of 
rivoceranib requires special attention to events that have a low incidence but may cause 
serious consequences or even deaths, including various types of bleeding and 
thrombotic events, cardiotoxicity (QT interval prolongation, arrhythmia) and liver 
toxicity. Please refer to the investigator’s brochure for more details on adverse drug 
reactions associated with rivoceranib mesylate. Currently, the known safety information 
on rivoceranib mesylate mainly comes from the experience of dose regimen of 850 mg 
QD, and the experience of 250 mg QD is relatively limited. 
Although the mechanism of action for SHR-1210 and rivoceranib is completely 
different, their pharmacological effects may extensively affect multiple organ systems 
of the body. Based on the preliminary safety data, and given that there could be 
overlapped adverse reactions associated with both drugs during the treatment of SHR-
1210 in combination with rivoceranib 250 mg QD, overlapped adverse reactions that 
require the investigator’s special attention include but not limited to: severe cutaneous

adverse reaction, hematological toxicity, abnormal liver function, diarrhea, anorexia, 
proteinuria and fatigue. 
1.3.2. 
Known Possible Benefits 
In the two currently ongoing phase II clinical studies in subjects with advanced HCC, 
the efficacy has been preliminarily shown for SHR-1210 alone or SHR-1210 in 
combination with rivoceranib. So the HCC subjects enrolled in this study may achieve 
partial or even complete response, and some subjects may obtain sustained stable 
disease. The above trial data will provide a strong guidance for the clinical practice for 
HCC treatment and allow more subjects to access and benefit from new therapeutic 
methods.

STUDY DESIGN 
3.1. 
Overall Design 
This is a randomized, open-label, international, multi-center, phase 3 trial to evaluate 
the efficacy and safety of PD-1 antibody SHR-1210 plus rivoceranib mesylate versus 
sorafenib as first-line therapy in subjects with incurable advanced HCC.  
The study will be conducted in subjects with incurable, locally advanced or metastatic 
HCC who did not receive systematic treatment previously. Primary efficacy endpoints 
include both OS and PFS evaluated by the BIRC based on RECIST v1.1, and 
approximately 510 subjects will be enrolled. Eligible subjects will be randomized to 
receive either SHR-1210 combined with rivoceranib mesylate (experimental arm) or 
sorafenib (control arm) in a 1:1 ratio. 
The stratification factors for randomization include:  
1. Macrovascular invasion and/or extrahepatic metastasis (presence vs. absence) 
2. Geographical region (Asia vs. countries outside of Asia) 
3. Baseline AFP (AFP < 400 ng/mL vs. AFP ≥ 400 ng/mL) 
Subjects will receive study treatment after being informed of all pertinent aspects of the 
study, signing the informed consent form and passing the screening for eligibility. 
Experimental arm: SHR-1210, 200 mg, via intravenous infusion, once every two weeks 
(Q2W) + rivoceranib 250 mg, p.o., once per day (QD), continuously, 4 weeks (28 days) 
per cycle of therapy. Control arm: sorafenib, 400 mg, p.o., twice per day (BID), 
continuously, 28 days per cycle of therapy. Study treatment will continue until the 
subject develops an intolerable toxicity, withdrawing informed consent, and disease 
progression confirmed by BIRC according to RECIST v1.1 (when the subject has 
disease progression assessed by the investigator according to RECIST v1.1, the 
investigator must submit the radiological data to BIRC immediately. If BIRC evaluates 
it as non-disease progression according to RECIST v1.1, the subject should continue to 
receive the study drug treatment and continue the tumor radiological evaluation; if 
BIRC confirms it as disease progression based on RECIST V1.1, at this time, the 
investigator needs to assess whether the subject still has clinical benefit. If the subject 
is considered to still have clinical benefit and meet the criteria for treatment beyond  
disease progresses (see Section 6.6 for details), the subject may continue to receive 
study medication; if the subject is no longer considered to have clinical benefit, the 
treatment may be discontinued), or other termination criteria specified by the protocol, 
whichever occurs first. 
Subjects will have safety visits on D1 and D15 of each cycle of therapy within the first 
3 cycles for both experimental and control arms. Beginning from the cycle 4, subjects 
will have safety visits on D1 and D15 of each cycle in the experimental arm; subjects 
in the control arm will only have safety visits on D1 of each cycle; refer to the

SCHEDULE OF ACTIVITIES for details. Subjects will continue with safety visits and 
survival follow-up after the end- of- treatment. The study design is shown in Figure 6. 
 
Figure 6. 
Study Design Chart 
Tumor radiological evaluation will be performed every 8 weeks (56 days) ± 7 days from 
the randomization through the first 48 weeks, to assess the efficacy, and every 12 weeks 
(84 days) ± 7 days after 48 weeks. During the trial period, radiological examination and 
evaluation can be added at any time if clinically indicated. Tumor radiological 
assessment will continue until the occurrence of disease progression confirmed by 
BIRC according to RECIST v1.1 criteria or study treatment discontinuation, whichever 
occurs later. Subjects who discontinue treatment for reasons other than BIRC-
confirmed disease progression (according to RECIST v1.1) will also continue with 
regular follow-up by tumor radiological assessments after study treatment is 
discontinued. 
If the subject withdraws informed consent before BIRC confirms disease progression 
according to the RECIST v1.1 criteria or the study treatment is discontinued, other anti-
tumor treatment has begun (except for traditional Chinese medicine), or the subject dies, 
there is no need to continue the radiological evaluation. If the subject does not meet the 
above criteria to stop radiological assessment, the efficacy evaluation of the three 
efficacy evaluation criteria (RECIST v1.1, mRECIST, imRECIST) needs to continue 
even if the disease progression under certain efficacy evaluation criteria occurs.  
Upon approval of Protocol v6.0, disease progression will be confirmed by the 
investigator per RECIST v1.1. If the investigator confirms non-disease progression, the 
subject should continue on study treatment and tumor radiological evaluation as 
required; if the investigator confirms as disease progression, the subject may continue 
to receive study treatment after disease progression at the investigator’s discretion (see 
Section 6.6). 
The study extension phase will be initiated when sufficient follow up is completed and 
the study is ended (at least 2 years follow up of the last subject randomized). The

purpose of the extension phase is to continue to provide access to study drugs for 
subjects who are still on study treatment and still derive clinical benefit at the time of 
end of study. Upon initiation of the extension phase, the Sponsor considers the safety 
and efficacy profile of the experimental treatment regimen within this study to have 
been sufficiently established and data analysis required for regulatory purposes to have 
been completed. The Sponsor will notify the sites when will the study enter the 
extension phase. 
In the extension phase, subjects randomized in the experimental arm will continue on 
SHR-1210 in combination with rivoceranib, and subjects randomized in the control 
arm may have the option to crossover to receive experimental treatment and the 
decision made is upon investigator’s clinical judgment. Subjects who are not eligible 
to crossover to experimental treatment per investigator clinical judgment can continue 
on sorafenib treatment. Subjects will continue to receive study treatment until they are 
no longer benefiting from treatment as assessed by investigator’s clinical judgment. 
The study clinical database will be closed at the initiation of the extension phase. 
Important safety information collection in the extension phase will be captured in the 
safety database. Only data collected prior to implementation of extension phase will 
be summarized in the clinical study report.

Lifestyle Requirements 
4.4.1. 
Contraception 
Male subjects with azoospermia (due to vasectomy or other underlying disease) and 
partners do not need to take contraception. 
Female subjects are considered as not of childbearing potential if: 
(1) Postmenopausal (defined as absence of menses for at least 12 months without other 
medical reasons; female subjects younger than 45 years of age without hormonal

contraception or hormone replacement therapy whose follicle-stimulating hormone 
(FSH) levels reached postmenopausal levels). However, in the absence of 12 months of 
amenorrhea, a single FSH measurement is insufficient; 
Or  
(2) having hysterectomy and/or bilateral ovariectomy, bilateral salpingectomy or 
bilateral tubal ligation/occlusion surgery at least 6 weeks prior to screening; 
Or  
(3) the presence of congenital or acquired conditions leading to infertility. 
Female subjects of childbearing potential and male subjects with partners who are 
women of childbearing potential are required to use to contraception and follow one of 
the following contraception requirements, from the time the subject signs the informed 
consent until at least 120 days after the last dose of study drug: 
(1) Abstinence (avoid heterosexual intercourse) †. 
Or 
(2) use a reliable and effective method of contraception during heterosexual intercourse. 
Reliable, effective methods of contraception include: 
Single method of contraception (any one of the following methods): 
• Intrauterine device (IUD) 
• Subcutaneous implant contraception  
Two methods combined contraception (two of the following methods must be used 
simultaneously): 
• Vaginal 
diaphragm/spermicide 
(cannot 
be 
combined 
with 
cervical 
cap/spermicide) * 
• Cervical cap/spermicide (only for women who have not given birth) *  
• Contraceptive sponge (only for women who have not given birth) * 
• Male condom or female condom (not used concurrently) 
• Hormonal contraception: Oral contraceptives (estrogen/progesterone or 
progesterone), contraceptive patch, vaginal contraceptive ring, or subcutaneous 
injection contraceptives 
† For those who choose to completely not have a sexual life, abstinence (avoiding 
heterosexual intercourse) can be used alone for contraception. Periodic abstinence (e.g., 
based on ovulation, symptomatology etc.) and external ejaculation are not reliable and 
effective contraception. 
In addition, the subject needs to be aware that once he/she stops using the selected 
contraceptive method, or he/she or his/her partner is suspected or confirmed to be 
pregnant, the investigators need to be notified immediately.

Subjects’ Withdrawal from the Study or Discontinuation of Study 
Treatment 
4.5.1. 
Criteria for Discontinuation of Study Treatment 
Discontinuation of study treatment do not represent withdrawal from the study. Subjects 
who discontinued study treatment should continue to complete the remaining study 
visits as required in the protocol. Subjects should discontinue study treatment when any 
of the following conditions occurs:  
 Subject requests discontinuation of study treatment;  
 Efficacy evaluation meets criteria for progression of disease confirmed by 
BIRC (according to RECIST v1.1), unless investigator considers the subject 
still has clinical benefit and meets the criteria for treatment beyond progression 
(Disease progression will be confirmed by the investigator per RECIST v1.1 
upon approval of Protocol v6.0; other procedures and criteria remain 
unchanged, see Section 6.6 of the protocol); 
 Pregnancy in female subject occurs during the study; 
 Unacceptable toxicity despite dose modification, or occurrence of adverse 
event, abnormal laboratory examination, or concomitant diseases, then it is no 
longer in the best interests of the subjects to continue study treatment according 
to the judgment of the investigator;   
 Overall deterioration of health status, inability to continue participation in the 
trial;  
 Significant protocol deviation or violations confirmed by sponsor, e.g., 
ineligibility of subjects after enrollment;  
 Termination of study by the sponsor;  
 
Other reasons for inability to continue study treatment, as considered by 
investigators.  
4.5.2. 
Criteria for Withdrawal from the Study 
Subjects can withdraw from the study voluntarily at any time, or at the request of the 
investigator or the sponsor for safety or behavioral reasons, or inability to comply with 
the visit schedule or procedure required in the protocol at his/her study site. 
The reasons for withdrawal from the study may include:  
 Withdrawal of the informed consent on participation in the study, and refusal 
of further follow-up;  
 Any conditions which require subject’s withdrawal, per Investigator’s 
discretion e.g., subject’s loss of the ability to express his/her wishes freely due 
to imprisonment or segregation;  
 Lost to follow-up;  
 Termination of study by the sponsor.

72 
4.5.3. 
The Procedures of Withdrawal from the Study or Discontinuation of 
Study Treatment 
Subjects should comply with the follow-up schedule specified in the protocol after 
discontinuation of study treatment. The efficacy and safety examination specified in the 
protocol at the end of treatment, and safety follow-up should be completed, and the full 
records of AEs and outcomes, concomitant medications/therapy should be provided. 
Investigators can advise or provide new or alternative therapeutic method to subjects 
according to their actual condition. The subjects with no progression of disease need to 
continue the radiological evaluation according to the scheduled frequency and time, 
until start of a new antitumor therapy or progression of disease. The radiological 
evidence on progression of disease should be obtained as much as possible for such 
subjects.  
If subject refuses to return to the site for further visit, his/her survival status should still 
be followed up, unless the subject withdraws the consent on disclosure of further 
information or continuous contact. If the subject requests withdrawal from the study 
clearly, the investigator should record the extent of subject’s request on withdrawal 
from the study procedure in a written form, i.e., only withdrawal from study treatment 
and/or withdrawal from post-treatment follow-up. When it is necessary to know the 
survival state, only the publicly available information should be used appropriately to 
determine whether the subject survives.  
4.5.4. 
Lost to Follow-Up 
Every possible effort must be made to know and report the subject’s status, including 
contact with the subject. Lost to follow-up is defined as no response to at least three 
contacts. The contact method includes but is not limited to any of the following: 
telephone, fax, message, social media tools and email. All the attempts to make contact 
should be recorded in the medical document. If the subject is confirmed to be dead, the 
study center will use a permitted method to acquire the information on death and cause 
of death. The study center can also utilize public resources, for example, community 
health registry and database, to obtain the contact information. If the subject’s status 
can still not be acquired after all the attempts have been made, investigators should 
report the last date when the subject is known to be survived and record it in the medical 
record.  
4.6. 
Early Termination or Suspension of Study 
The study can be terminated or interrupted prematurely if the reason is sufficient. This 
may be due to the decision of regulatory agency, IRB/EC’s opinion, Data Monitoring 
Committee (DMC)’s opinion, or efficacy or safety issues of the investigational product, 
or base on the sponsor’s judgment. In addition, Jiangsu Hengrui Pharmaceuticals Co., 
Ltd. reserves the right to stop research and development of SHR-1210 at any time. The 
party who makes the decision on termination/interruption of the study will send a 
written notice which records the reason for study termination or interruption to 
investigators, sponsor and regulatory authorities. Investigators should notify the ethics 
committee and the sponsor immediately and provide relevant reasons. 
The reasons for premature termination or interruption of the study may include:

 
Discovery of unexpected, significant or unacceptable risk;  
 
The efficacy data support early termination of the study; 
 
Low compliance with study requirements. 
Once the aforementioned drug safety, protocol compliance and data quality issues 
causing study interruption are solved and after obtaining the consent of the sponsor, the 
ethics committee or the local regulatory authority, the study can proceed.

Storage and Stability 
Investigators or their authorized representatives (e.g., pharmacist) will ensure all the 
investigational products are stored in a controlled secure area that meets the storage 
conditions (see storage conditions in Section 5.1.2), and the storage is in accordance 
with the requirements of applicable laws. 
The study center must be able to record the highest and lowest temperatures per working 
day for all study drugs storage locations (e.g., freezing, cold storage or room 
temperature). The cycle of recording should start with receiving drugs until all the 
remaining study drugs are recovered. Even though there is a continuous monitoring 
system, the study center should also keep record logs to ensure the correct storage 
temperature. The temperature monitoring devices and storage devices (e.g., freezer) 
should be checked on a regular basis, as to ensure it functions normally.  
Any deviations from the recommended storage conditions on the product label should 
be reported promptly to the sponsor. The study center should take active measures as

400 mg, twice per day (BID), orally under fasted state (at least 1 
hour prior to a meal or 2 hours after a meal), for continuous 
administration, one treatment cycle is 4 weeks (or 28 days). 
 
If a subject in the experimental arm (SHR-1210 in combination with rivoceranib) 
develops a treatment-related AE that leads to permanent discontinuation of rivoceranib 
and the investigator determines that the subject can benefit from SHR-1210 
monotherapy, the subjects may continue to receive SHR-1210 monotherapy until 
meeting the criteria for study treatment discontinuation as specified in this protocol, 
and vice versa. In addition, during the study treatment period, if a subject in the 
experimental arm develops a treatment-related AE that leads to temporary 
discontinuation of SHR-1210 or rivoceranib, the subject may continue to receive 
monotherapy, and the combination therapy can be resumed only after the toxicity 
resolves. 
Study treatment will continue until the subject develops an intolerable toxicity, 
withdrawal of informed consent, and disease progression confirmed by BIRC according 
to RECIST v1.1 (when the subject appears to have met the criteria for disease

progression assessed by the investigator according to RECIST v1.1, the investigator 
must submit the radiological data to BIRC immediately. If BIRC evaluates it as non-
disease progression according to RECIST v1.1, the subject should continue to receive 
the study drug treatment and continue the tumor radiological evaluation; if BIRC 
confirms it as disease progression based on RECIST V1.1, at this time, the investigator 
needs to assess whether the subject still has clinical benefit. If the subject is considered 
to still have clinical benefit and meets the criteria for continuing treatment after the 
disease progresses [see Section 6.6 for details] the subject may continue to receive study 
treatment; if the subject is no longer considered to have clinical benefit , the treatment 
may be discontinued),or other discontinuation criteria specified in the protocol, 
whichever occurs first. Administration 3 days after the date of intended SHR-1210 
administration will be considered as delayed administration. Upon the approval of 
protocol v6.0, disease progression will be only judged by investigator per RECIST v1.1. 
If a subject missed a dose of rivoceranib and it was ≥12 hours away from next planned 
dose, the rivoceranib dose should be made up on current day, if < 12 hours away from 
next planned dose, that dose should be skipped and dosing resumed at subsequent dose 
as planned, without doubling the dose of the next day. If a subject receives an overdose 
of rivoceranib, contact the investigator immediately. 
If a subject missed a dose of sorafenib at a scheduled timepoint, the missed dose will 
not be made up and the next dose should be taken as planned. If the subject has an 
overdose of sorafenib, contact the investigator immediately.  
Any vomiting after administration with sorafenib or rivoceranib should not be made up.

Dose Adjustment and Safety Management 
5.1.6.1. Dose Adjustment 
5.1.6.1.1. Criteria for Dose Adjustment of SHR-1210  
Dose adjustment is not allowed for SHR-1210, only dose interruption is allowed.  
5.1.6.1.2. Criteria for SHR-1210 Dose Delay 
The dose of SHR-1210 should be delayed if the following conditions occur:  
• 
Any ≥ Grade 2 drug-related non-cutaneous AE, except Grade 2 drug-related fatigue 
or laboratory abnormalities (unless otherwise specified);  
• 
Any Grade 3 drug-related cutaneous AE;  
• 
Any Grade 3 drug-related laboratory abnormalities, except Grade 3 abnormal 
amylase or lipase unrelated with the symptoms and clinical manifestations of 
pancreatitis;  
• 
The administration will be delayed if the following AST, ALT or total bilirubin 
abnormalities occur:  
– AST and ALT at baseline are within the normal range, and drug-related 
elevated AST or ALT reaches >3×ULN;  
– AST or ALT at baseline elevates no greater than Grade 1, and drug-related 

Study Drug Number: SHR-1210 
Protocol Number: SHR-1210-III-310 
Version 6.0, 21 Sep 2022 
 
HENGRUI CONFIDENTIAL 
77 
elevated AST or ALT reaches >5×ULN; 
– AST or ALT at baseline elevates no greater than Grade 2, and drug-related 
elevated AST or ALT reaches >2 times the baseline or either AST or ALT 
reaches >8×ULN (whichever is lower); 
– Total bilirubin at baseline is within the normal range, and drug-related elevated 
total bilirubin reaches >2×ULN; 
– Total bilirubin at baseline elevates no greater than Grade 1, and drug-related 
elevated total bilirubin reaches >2 times the baseline. 
• 
The administration needs to be delayed for any AE, laboratory abnormalities or 
complications, as judged by investigators;  
• 
If RCEP occurs during the trial, refer to APPENDIX 7 for detailed suggestions on 
grade and management of RCEP. 
• 
If subjects have fever (>38°C) and need medication, or obvious symptoms of 
asthma, shortness of breath, and asphyxia during the trial, SHR-1210 will not be 
given any more at this or next scheduled time point before the symptom is 
recovered. SHR-1210 will be resumed after the symptom is relieved and stabilized 
for more than 7 days, and pneumonia will be excluded through radiological 
examination prior to administration if necessary.  
Subjects who need delayed dose should be monitored every week, and the frequency of 
monitoring can be increased if clinically indicated. It is recommended to monitor liver 
function every three days, until the highest value of AST or ALT starts to decrease. 
When meeting the criteria for resumption of medication (see Section 5.1.6.1.3), the 
study drug can be resumed.  
Tumor evaluation still needs to proceed for all subjects, as required in the protocol, 
regardless of dose delay. During the period of dose delay, safety visits and laboratory 
examinations should also be performed as planned in the protocol, or more frequently 
when clinically indicated (see SCHEDULE OF ACTIVITIES Footnote [4]).  
5.1.6.1.3. Criteria for Resumption of SHR-1210  
When drug-related AE recover to Grade 1 (or lower grade) or baseline level, SHR-1210 
study treatment can be resumed, except the following:  
• 
The therapy can be resumed for the subjects with Grade 2 fatigue that has not been 
recovered;  
• 
The therapy can be resumed for Grade 2 cutaneous AE;  
• 
Subjects with AST, ALT or TBIL grade 1 elevation at baseline, and delayed SHR-
1210 for reasons other than drug-related hepatic AE, the therapy can be resumed in 
the presence of AST, ALT or TBIL Grade 2 elevations; 
• 
As the subjects who delay the dose for drug related elevated AST, ALT or TBIL, 
when these parameters are recovered to baseline CTCAE grade or normal (see 
Section 5.1.6.1.4) but who have not reached the criteria for permanent 
discontinuation of the treatment, the study drugs can be resumed;

• 
The therapy can be resumed for drug related grade 2 laboratory abnormalities in 
GGT and/or ALP increase;  
• 
In case the drug related endocrine disorder can be sufficiently controlled only with 
hormone replacement at physiological dose, the treatment can be resumed.  
The dose of SHR-1210 is allowed to be delayed for up to 12 weeks, as calculated from 
the last dose. In case the subject still does not reach the criteria for dose resumption 
after delay for 12 weeks, the study drug needs to be discontinued permanently, except 
the exception mentioned in the Section 5.1.6.1.4. The guideline on management of 
adverse reactions is seen in APPENDIX 6 in detail. Rules for hepatic AEs management 
can be referred to in Section 5.1.6.2.2. 
5.1.6.1.4. Criteria for Permanent Discontinuation of SHR-1210 
The study drug SHR-1210 must be discontinued permanently when the following 
conditions occur:  
• 
Any Grade Stevens-Johnson syndrome and toxic epidermal necrolysis; 
• 
Any Grade 2 drug-related uveitis, ophthalmodynia and blurred vision that has no 
response to local therapy and is not recovered to Grade 1 after delayed dose; or the 
above AE requiring systemic therapy;  
• 
Any Grade 3 drug-related non-cutaneous AE lasting for >7 days, except the 
following:  
- 
When any Grade 3 drug-related uveitis, myocarditis, encephalitis, pneumonia, 
bronchospasm, hypersensitivity or infusion reaction occurs, the study 
treatment must be terminated;  
- 
In case the drug-related endocrine disorders can be sufficiently controlled only 
with hormone replacement therapy at physiological doses, the treatment does 
not need to be terminated; 
-

5.1.6.1.5. Criteria for Dose Modification of Rivoceranib 
Dose modification methods resulted from rivoceranib-related toxicities include dose 
interruption, adjustment of administration schedule (first adjustment: take 5 days

followed by interruption of the drug for 2 days (5 days on 2 days off [5 on 2 off]); re-
adjustment: once every other day [QOD]) and termination of rivoceranib. After the 
administration schedule of rivoceranib is adjusted during the study, will not allow going 
back to initial administration schedule. 
If rivoceranib-related AEs definitely occur during the trial, for example, hypertension, 
proteinuria, hand-foot syndrome, rivoceranib can be interrupted; when the toxicity is 
recovered, maintenance of dose at the current dose level, adjustment of administration 
schedule or discontinuation of dose can be given as appropriate. The subject can 
continue to receive SHR-1210 monotherapy after rivoceranib is discontinued. 
Referring to the experience in phase II clinical studies, the investigator must interrupt 
the dose of SHR-1210 and rivoceranib at the same time (See Section 5.1.6.1.2 criteria 
for SHR-1210 dose delay reference), for the confirmed immune-related toxicities 
during the trial, in particular immune pneumonia/pneumonitis, hepatitis, increased AST, 
ALT, bilirubin, diarrhea or colitis, increased creatinine. The dose can be resumed when 
the toxicity is recovered to ≤Grade 1 or baseline level (for subjects with abnormal ALT, 
AST and TBIL during baseline). It is recommended to resume SHR-1210 first, and then 
administer rivoceranib after 7-14 days of no significant abnormality observed after 
administration of SHR-1210. The subsequent administration schedule for rivoceranib 
will be adjusted (first adjustment: 5 days on 2 days off [5 on 2 off]; re-adjustment: once 
every other day [QOD]).  
Changes in blood pressure should be monitored routinely during rivoceranib 
administration. It is advisable to interrupt the dose of rivoceranib firstly in case Grade 
3 elevated blood pressure occurs (systolic blood pressure ≥ 160mmHg or diastolic blood 
pressure ≥ 100mmHg or more than one antihypertensive agent is needed) and perform 
antihypertensive therapy under specialist’s instructions. Rivoceranib can be resumed 
when the blood pressure is decreased to normal range (systolic blood pressure < 140 
mmHg and diastolic blood pressure < 90 mmHg). If there is still hypertension, the 
administration schedule of rivoceranib must be adjusted. For subjects with hypertensive 
crisis (systolic blood pressure ≥ 180 mmHg or diastolic blood pressure ≥ 120mmHg, 
and/or with progressive insufficiency of target organs), the rivoceranib should be 
discontinued immediately and symptomatic treatment should be given actively 
(antihypertension, dehydration, anti-convulsion and so on).  
Dose interruption use and adjustment of administration schedule of rivoceranib is 
needed for ≥ Grade 3 hematological toxicities or ≥ Grade 2 non-hematological 
toxicities; for the non-hematological toxicities, symptomatic treatment can be given 
actively for controllable nausea, vomiting and fever with determined cause (<38oC), 
with no need of immediate dose interruption or adjustment of administration schedule.  
Symptomatic treatment should be given promptly for the symptom/sign or laboratory 
abnormalities during the trial, and it is recommended to refer to the following table for 
corresponding dose modification:

For the significant toxicity that is still ongoing after symptomatic treatment during the 
trial, including Grade 2 non-hematological toxicities lasting for two weeks or more 
(except asymptomatic Grade 2 hypertension), laboratory abnormalities (except 
proteinuria <2g/24h), investigators can consider dose interruption based on the 
subject’s tolerability, and adjust the administration schedule of rivoceranib 
subsequently after the toxicities are recovered.  
During the study, in combination with the recommendations on the dose adjustment 
above, investigators can give appropriate dose adjustment through comprehensive 
analysis of the occurrence of drug-related toxicities (e.g., multiple Grade 2 toxicities 
related with the study drug, poor intolerability to study drug), and can consider adjust 
the administration schedule of rivoceranib after dose interruption and recovery of the 
toxicity.  
5.1.6.1.6. Criteria for Dose Modification of Sorafenib 
Subjects receiving sorafenib will be given 400 mg (two tablets, 200 mg per tablet) orally, 
twice per day, under fasted state (at least 1 hour prior to meal or at least 2 hours after a 
meal) with a cup of warm drinking water.  
Dose adjustment resulted from drug-related toxicities include dose interruption, dose 
reduction and discontinuation. When dose reduction is required during treatment, 
sorafenib should be reduced to 400 mg once per day, if additional dose reduction is 
required, could refer to the locally approved drug label or local standard of care 
practice/treatment guideline. It is not allowed for dose level less than 400mg every other 
day. The criteria for interruption or discontinuation of sorafenib can be found in the 
label of sorafenib tosylate tablets approved by the local health authority in detail or 
local standard of care practice/treatment guideline. For any dose interruption, sorafenib 
treatment can be interrupted for up to 30 days.  
Cutaneous toxicities are the most common adverse reactions of sorafenib. Cutaneous 
related dose modification refer to Table 9 or based on the sorafenib label of approved 
by the local health authority. Other toxicities related dose modifications refer to 
sorafenib label approved by the local health authority.  
In principle, dose escalation is not allowed; however, in accordance with the package 
insert of sorafenib tosylate tablet approved by the FDA, “Following improvement of 
Grade 2 or 3 dermatologic toxicity to Grade 0–1 after at least 28 days of treatment on a 
reduced dose of sorafenib, the dose of sorafenib may be increased one dose level from 
the reduced dose.” The investigator may make the decision based on the subject’s 
condition.

5.1.6.2. Safety Management on the Safety of Oncology Drugs 
5.1.6.2.1. Rules for Safety Management of Immuno-Oncology Drugs 
The AEs induced by Immuno-Oncology (I-O) drugs vary from other types of antitumor 
drugs, the severity and duration are special. SHR-1210 belongs to this type of drugs, 
thus it is required to achieve early identification and management of the AEs induced 
by it, in order to reduce the incidence of serious toxicities. To identify I-O drug related 
AEs, the investigator may refer to the following definition and diagnosis of immune-
related colitis, pneumonitis and hepatitis: 
Definition of immune-related colitis: A disorder characterized by inflammation of the 
colon. 
Diagnostic work-up of immune-related colitis suggested as follows: 
1) Symptoms include diarrhea, abdominal pain, hematochezia, weight loss, fever and 
vomiting. 
2) To rule out infection: For Grade 2 AEs, work-up of blood (complete blood cell 
count, comprehensive metabolic panel, thyroid-stimulating hormone, erythrocyte 
sedimentation rate, C-reactive protein) and stool (bacterial culture, Clostridium 
difficile, parasites, viral etiology) are recommended to be performed; radiological 
(e.g., CT scan of the abdomen and pelvis) as well as endoscopy and biopsy should 
be considered. For Grade 3-4 AEs, all the work-up listed above for Grade 2 AEs 
should be completed immediately.

HENGRUI CONFIDENTIAL 
85 
3) Consider repeating endoscopy for subjects who do not respond to 
immunosuppressive agents. 
 
Definition of immune-related pneumonitis: Focal or diffuse inflammation of the lung 
parenchyma (typically identified on CT radiological). 
Diagnostic work-up of Immune-related pneumonitis suggested as follows: 
1) Respiratory events like cough and dyspnea; 
2) Thoracic CT scan; 
3) Hematology: including complete blood cell count, urea nitrogen, blood electrolytes, 
creatinine, liver function tests, thyroid function tests, blood calcium, C-reactive 
protein, and erythrocyte sedimentation rate; 
4) Infection should be ruled out by bronchoscopy, especially for ≥ Grade 2 AEs; 
5) Consider sputum sample and screening for viral, opportunistic or specific bacterial 
infections depending on the clinical context. 
 
Definition of immune-related hepatitis: A disorder characterized by a viral pathological 
process involving the liver parenchyma. 
Diagnostic work-up of immune-related hepatitis suggested as follows: 
1) Assessed for signs and symptoms of hepatitis; 
2) Transaminases and bilirubin measured before every cycle of treatment; 
3) If hepatitis develops, disease-related causes, concomitant drug administration 
(including alcohol) and infectious causes, particularly viral hepatitis, should be 
ruled out. Other thromboembolic and outflow obstructive etiology should also be 
excluded through radiological; 
4) Liver biopsy may be considered in assisting in the differential diagnosis of more 
severe hepatic reactions. 
In addition, the investigator may refer to the rules for safety management of similar 
products in overseas markets to facilitate evaluation and management of I-O drug 
related AEs occurring in the following systems:  
• 
Gastrointestinal tract 
• 
Kidney 
• 
Lung 
• 
Liver 
• 
Endocrine 
• 
Skin 
APPENDIX 6 and APPENDIX 7 provide the recommended treatment procedures for 
common immune-related adverse reactions. Note that the rules for management of 
hepatic irAEs have been amended in this protocol (see Section 5.1.6.2.3 below).

5.1.6.2.2. Principles of Management for Immune-Related Adverse Events 
In overall principle, according to the severity of adverse reaction, interruption of SHR-
1210 is taken as the main measure, resumption of SHR-1210 can be considered when 
the severity of adverse event has recovered to Grade 1 or below, and SHR-1210 should 
be discontinued permanently when serious Grade 3 or life-threatening Grade 4 adverse 
event occurs (For details, refer to Sections 5.1.6.1.2, 5.1.6.1.3 and 5.1.6.1.4 of this 
protocol which state criteria for dose delay, dose resumption, and permanent 
discontinuation of SHR-1210). 
Management of immune-related adverse events should be based on the medical practice 
of the research center and the guidelines.  Recommended treatment procedures for 
common immune-related adverse events are detailed in APPENDIX 6 (Note that the 
rules for management of hepatic irAEs have been amended in this protocol [see Section 
5.1.6.2.3 below]). The classification and management of reactive capillary endothelial 
proliferation (RCEP) are detailed in APPENDIX 7.  
5.1.6.2.3. Rules for Management on Hepatic Adverse Events of SHR-1210 
Below are suggestions on management of hepatic AEs that may occur in the 
experimental arm during the SHR-1210 treatment period of this study: 
• 
If the dose is delayed for 3-5 days and AST or ALT level is not improved but even 
exacerbated, cortisol, i.e., methylprednisolone 0.5-2 mg/kg/day or equivalent oral 
drugs, will be given;   
• 
In case of AST or ALT >8 times of ULN, cortisol, i.e., methylprednisolone 1-
2 mg/kg/day or equivalent oral drugs, will be given immediately, and meanwhile, 
a consultation from the department of gastroenterology is advised;  
• 
If AST or ALT level is not improved but even exacerbated 3-5 days after the start 
of corticosteroids treatment, other immunosuppressants may need to be added, such 
as mycophenolate 1g BID;  
• 
Once AST or ALT is decreased by one CTCAE Grade, the dose can be decreased 
gradually in no less than one month.  
The study drug can be resumed when AST or ALT is recovered to baseline level, unless 
the criteria for permanent discontinuation is reached.  
5.1.6.2.4. Infusion Reaction of SHR-1210 
As SHR-1210 is one fully humanized monoclonal antibody, the possibility of infusion 
or allergic reaction is low, and preventive medication is not needed prior to infusion. 
Allergic reaction is most likely to occur within 24h after infusion. Once the allergic 
reactions occur, the infusion should be slowed down or interrupted based on the 
condition, and clinical supportive treatment is needed. The preventive medication 
should be given prior to the subsequent doses. The allergic reactions are possibly 
characterized by fever, intolerance of cold, chills, headache, rash, pruritus, arthralgia, 
low or high blood pressure, or bronchospasm. All the Grade 3 or 4 infusion reactions 
should be reported to the sponsor within 24 hours and reported as SAE in case of 
meeting the criteria for SAE. See detailed reporting methods in Section 8.2.

1. Hand-and-foot syndrome 
Hand-foot syndrome (HFSR): is palmar-thenar hypoesthesia or erythema at extremities, 
one of the cutaneous toxicity, is more obvious at the pressed or forced area when it 
occurs. It may appear in tumor subjects during chemotherapies or molecular targeted 
therapies. HFSR is characterized by numbness, hypoesthesia, paresthesia, stabbing pain, 
analgesia or edema pain, cutaneous swelling or erythema, desquamation, chapping, 
hardened blister or serious pain, etc. 
Grading: 
Grade 1: numbness, dysesthesia/paresthesia of hand and/or foot, painless swelling or 
erythema and/or discomfort that has no effect on normal activities. 
Grade 2: painful erythema and swelling of hand and/or foot and/or discomfort that 
affects subject’s daily life. 
Grade 3: moist desquamation, ulcer, blister or serious pain of hand and/or foot and/or 
serious discomfort that makes subject unable to work or engage in daily activities. 
Intense pain, loss of skin function, comparably rare. 
Symptomatic treatment and measures: 
Recommended some necessary supportive treatments include intensive skin care, 
keeping skin clean to avoid secondary infection; avoiding pressure or scratching; using 
moisturizing cream or lubricant, including local use of lotion or lubricant containing 
urea and corticosteroids; and local use of anti-fungal or antibiotic therapy when 
necessary. 
Note: If ≥ Grade 3 hand-foot syndrome occurs for consecutive three times, with an 
aggravating tendency, the administration of rivoceranib should be terminated. 
2. Hypertension 
Subjects should be enrolled strictly in accordance with the requirement of blood 
pressure in the inclusion/exclusion criteria, subjects with hypertension can achieve 
controlled through adjustment of the dose of antihypertensive agents or adding of new 
antihypertensive agents prior to taking the study drugs, the blood pressure should be 
controlled within 140/90 mmHg.   
Monitoring and management of hypertension: 
Daily blood pressure monitoring (based on the average of BP readings acquired from ≥ 
2 measurements) is recommended after the initiation of rivoceranib mesylate treatment. 
Once hypertension occurs, the following treatment can be given: Angiotensin II 
receptor blockers (ARB), angiotensin-converting enzyme inhibitors (ACEI), β receptor 
blockers, etc. Or combined use of the aforementioned drugs.  
If subjects have hypertension or exacerbation of hypertension during administration, 
should take following actions:  
1) Adjusting the administration of study drugs as specified in the protocol (see 
Section 5.1.6.1.5);  

Study Drug Number: SHR-1210 
Protocol Number: SHR-1210-III-310 
Version 6.0, 21 Sep 2022 
 
HENGRUI CONFIDENTIAL 
89 
2) Starting to take antihypertensive agents or adjusting the dose.  
Advise subjects to record daily blood pressure measurements in a subjects’ diary. If they 
are taking hypertension drugs at the same time, they are required to keep a detailed 
record of the drug name, dosage, method and frequency of use, and related complaints 
or symptoms of discomfort.  
The hypertension treatment drugs are recommended as below:  
1) Angiotensin-converting enzyme inhibitors (ACEI);  
2) Angiotensin II receptor antagonists (ARB);  
3) dihydropyridine calcium channel antagonists;  
4) β receptor blockers.  
Use of diuretics is not recommended for anti-hypertensive therapy; nicardipine, 
diltiazem and verapamil with CYP3A4 inhibitory effect are prohibited. Rivoceranib 
mesylate should be discontinued in subjects with hypertensive crisis.   
3. Proteinuria  
Proteinuria should be closely monitored for all the subjects throughout the treatment, 
and intensively monitored in subjects who have history of hypertension; the 24-hour 
urine protein quantification must be performed for the subjects with urine protein ≥2+. 
Note: Rivoceranib mesylate shall be discontinued in case nephrotic syndrome occurs.  
4. Hemorrhage of digestive tract  
Active symptomatic treatment should be given when gastrointestinal hemorrhage 
occurs, including persistently positive result of fecal occult blood, haematemesis or 
bloody stool. The subjects who are judged as upper gastrointestinal hemorrhage should 
be fasted and given acid suppression agents, drugs for gastric mucosa protection 
hemostasis (Transamin, Reptilase, etc.) treatment, and octreotide can be used when 
necessary; hemostasis, blood transfusion and supportive treatments will be given for 
those with lower gastrointestinal hemorrhage; surgical assistance may be required 
immediately if the hemorrhage can not be controlled. Adjustment of medication in 
accordance with the principle in Section 5.1.6.1.5 in the protocol.   
5. Thrombosis  
Rivoceranib mesylate should be discontinued immediately for any arterial thrombosis 
(e.g., cerebral ischemia, stroke, angina pectoris, myocardial infarction, etc.). 
Rivoceranib mesylate should be temporarily discontinued in case symptomatic venous 
thrombosis occurs.   
Symptomatic treatment, surgery or anticoagulants should be given immediately for 
thrombotic symptoms.

5.1.6.2.6. Rules for Management of Adverse Events of Sorafenib 
1. Skin toxicity: 
Hand-foot cutaneous reactions and rash are the most common adverse reactions of 
sorafenib. Usually, the rash and hand-foot skin reactions are mostly CTCAE Grade 1-2 
and mostly occur within 6 weeks after the start of administration of sorafenib. 
Recommended necessary symptomatic and supportive treatments include intensive skin 
care, keeping skin clean to avoid secondary infection; avoiding pressure or scratching; 
using moisturizing cream or lubricant, including local use of lotion or lubricant 
containing urea and corticosteroids; and local use of anti-fungal or antibiotic therapy 
when necessary. Subjects with serious and persistent cutaneous toxicities may need to 
discontinue sorafenib permanently. Permanently discontinued for the serious cases. 
2. Gastrointestinal side effects: 
It is one of the common adverse reactions of sorafenib and mainly characterized by 
abdominal pain and diarrhea, which are generally mild-to-moderate and may be 
associated with the direct irritation of gastrointestinal mucosa of sorafenib after a long 
absorption in digestive tract and change of pH over time during its metabolism. 
Generally, the symptoms can be relieved through eating less residue, low-fiber diet, and 
digestible food. Subjects with serious diarrhea need to be closely observed. Infusion 
should be given as supportive treatment in case of dehydration, which would supply 
enough water and electrolytes.  
3. Hypertension: 
The incidence of hypertension will be increased in subjects given sorafenib. Drug-
related hypertension is mostly mild-to-moderate, usually occurs in early stage after 
taking medicine, and can be controlled with routine antihypertensive agents. The blood 
pressure should be monitored routinely and controlled within 140/90 mmHg. Advise 
subjects to record daily blood pressure measurements in the dairy card in detail. 
Wherever necessary, high blood pressure will be treated in accordance with standard 
antihypertensive regimen, and chief complaints or symptoms as well as dosing 
information (e.g., drug name, dose, route of administration and frequency) will be 
recorded in detail. Permanent discontinuation of sorafenib needs to be considered for 
subjects who still have serious or persistent hypertension after use of antihypertensive 
agents or have hypertensive crisis.  
4. Hemorrhage: 
The incidence of hemorrhage may be increased after administration of sorafenib. Active 
symptomatic treatments should be given when gastrointestinal hemorrhage occurs, 
including persistently positive result of fecal occult blood, hematemesis or bloody stool. 
The subjects who are judged as upper gastrointestinal hemorrhage should be fasted and 
given acid suppression agents, drugs for gastric mucosa protection, hemostasis 
(Transamin, Reptilase, etc.) treatment, and octreotide can be used when necessary; 
hemostasis, blood transfusion and supportive treatments will be given for those with 
lower gastrointestinal hemorrhage; surgical assistance may be required immediately if 
the hemorrhage can not be controlled. Once treatment is needed, it is advisable to

HENGRUI CONFIDENTIAL 
91 
consider permanent discontinuation of sorafenib. Hemorrhage or elevated INR occurs 
occasionally in part of subjects taking sorafenib and warfarin simultaneously. INR and 
PT should be detected routinely and attention should be paid to the sign of clinical 
hemorrhage in subjects given concomitant warfarin.  
5. Myocardial ischemia and/or myocardial infarction: 
Discontinuation of sorafenib should be considered for subjects with drug-related 
myocardial ischaemia and/or myocardial infarction.  
6. Gastrointestinal perforation: 
Gastrointestinal perforation is rare. The incidence of gastrointestinal perforation is less 
than 1% reported in subjects given sorafenib. Once it occurs, sorafenib should be 
discontinued.  
7. Liver impairment: 
Sorafenib is mainly eliminated via liver, and its exposure will be elevated in the subjects 
with hepatic impairment. Symptomatic and supportive treatment must be taken, the 
dose of sorafenib must be reduced or interrupted in case of drug related abnormal 
hepatic function. And discontinuation of the treatment should be considered if the 
symptom is serious and ≥ Grade 3 on an ongoing basis.  
Refer to the label of sorafenib tosylate tablets for details.  
5.2. 
Management, Distribution and Recovery of Drugs 
5.2.1. 
Drug Preparation 
The study drug should be prepared by qualified person in accordance with the 
brochure of study drug.  
5.2.2. 
The Disposal of Remaining Drugs 
Investigators or their authorized representatives should record the date and dose of the 
drug administered for each subject. The residual investigational products will return to 
the sponsor regularly for destruction after being counted. If the remaining drugs should 
be destroyed at study sites, investigators must ensure the destruction is in accordance 
with applicable environmental laws and regulations, unit policies and other applicable 
terms, also need to provide relevant procedures for destruction. All the destructions 
should be well recorded. 
5.3. 
Concomitant Therapy 
All treatments and medications (excluding solvent) used from 28 days prior to the 
signature of informed consent form to the end of safety follow-up should be recorded 
in the eCRF with raw data strictly in accordance with the GCP. If adverse events occur, 
the subject should be closely observed, as well as actively given symptomatic treatment 
if necessary, which is fully documented in medical records, and the drug and non-drug 
treatment used shall be recorded and specified in the eCRF. Only the concomitant

medication/therapy that is used to manage the study drugs related AE/SAE should be 
recorded after the above collection periods.  
5.3.1. 
Prohibited or Cautiously Used Medications and Treatments During the 
Study 
5.3.1.1. Drugs and Therapies Prohibited for All the Subjects During the Study 
Subjects are prohibited from using modern traditional Chinese medicines that have been 
approved by the NMPA (or by regulatory authorities in other countries) for the 
indication of HCC (including but not limited to Delisheng Injection, Kanglaite Injection, 
Aidi Injection, Huaier Granule and Ganfule Tablets) and immune-modulators 
(including but not limited to interferon, interleukin-2, thymosin, etc.) during the study.   
During the treatment period of this study, subjects are not allowed to receive any local 
therapies against liver tumor lesion and targeted lesion (except palliative local therapies 
described in Section 5.3.2.4), and other systemic antitumor therapies, such as 
chemotherapies, molecular targeted therapies, hormone therapies, immunotherapies, 
and so on. 
Subjects are not allowed to use other investigational products for antitumor therapy 
during the treatment period of this study. 
Section 4.2 (Exclusion Criteria) of the protocol describes other drugs prohibited in this 
study.  
5.3.1.2. Drugs Prohibited for Subjects Given SHR-1210 During the Study  
Subjects are not allowed to receive immunosuppressive therapies simultaneously 
during the treatment period of this study (except management on the treatment-related 
adverse events). 
Systemic corticosteroid cannot be used at the dose of >10 mg/day (Prednisone or 
equivalent) during SHR-1210 treatment period, except for treatment-related AEs 
treatments or short-term preventive therapies. SHR-1210 will be resumed until systemic 
corticosteroid dose has been reduced at ≤10 mg/day (Prednisone or equivalent). 
Vaccination of live vaccine are prohibited within 4 weeks prior to the first dose of study 
drugs until 60 days after the last dose.  
5.3.1.3. Drugs Used Cautiously or Prohibited for Subjects Given Rivoceranib 
During the Study  
There was a study conducted by Bao et al [24], in which apatinib (also known as 
rivoceranib) was evaluated for its in vitro inhibitory effect on the major CYP enzymes 
including CYP3A2/4, CYP2B1/6, CYP2C9/11, CYP2D1/6, and CYP2E1 using human 
and rat microsomes. The IC50 and IC50-shift results indicated that rivoceranib might 
not be a time-dependent inhibitor. Rivoceranib was a weak inhibitor of human CYP2E1 
(IC50>10 μM) but inhibited CYP2B6/2B1 and CYP2D6/2D1 in a competitive way 
(Ki = 3.84/0.59 and 5.41/0.87 μM), and inhibited CYP3A4/3A2 and rat CYP2E1 in a 

Study Drug Number: SHR-1210 
Protocol Number: SHR-1210-III-310 
Version 6.0, 21 Sep 2022 
 
HENGRUI CONFIDENTIAL 
93 
mixed way (Ki = 11.50/1.83 and 13.06 μM). On CYP2C9, Rivoceranib exhibited the 
noncompetitive inhibition (Ki = 0.71 μM) while it inhibited CYP2C11 uncompetitively 
(Ki = 3.30 μM). These results are consistent with the findings in the JHM and LSK IB, 
in which rivoceranib has the most potent inhibitory effect on CYP2C9, with lesser on 
CYP3A4 and CYP2C19.  
• In vitro studies have shown that rivoceranib is mainly metabolized by the liver 
P450 enzymes CYP3A, CYP2C9, and CYP2C19, strong inhibitors and 
inducers of CYP3A and CYP2C19 will significantly increase or decrease 
clearance of rivoceranib with increased or decreased exposures of rivoceranib. 
Therefore, the strong inhibitors and inducers of CYP3A and CYP2C19 will be 
prohibited (see Appendix 11 for listings of strong inhibitors and inducers of 
CYP3A and 2C19, there are no strong inhibitors or inducers of CYP2C9).  
• Sensitive substrates of CYP3A4 will be used with caution.  
• As the potential DDI for rivoceranib as a perpetrator of CYP2C9 exists, the 
following instructions will be implemented until further information is 
available: Drugs metabolized by CYP2C9 with narrow therapeutic index: 
warfarin, and phenytoin, will be prohibited. Drugs that are sensitive substrate 
of CYP2C9, such as celecoxib will be used with caution. 
• 
Drugs metabolized by CYP2D6 with narrow therapeutic index thioridazine, 
and pimozide, will be prohibited. Drugs that are sensitive substrates of 
CYP2D6 atomoxetine, desipramine, dextromethorphan, metoprolol, nebivolol, 
perphenazine, tolterodine, and venlafaxine will be used with caution. 
The following transporter substrates with narrow therapeutic index are prohibited: P-
gp substrates dabigatran, and digoxin, MATE1, MATE-2K, OCT2 substrate dofetilide 
(FDA’s Web site on Drug Development and Drug Interactions can be found at 
http://www.fda.gov/Drugs/DevelopmentApprovalProcess/DevelopmentResources/Dr
ugInteractionsLabeling/ucm080499.htm and drug bank for narrow therapeutic index 
https://www.drugbank.ca/categories/DBCAT003972. See Appendix 11) 
The transporter inhibitors are reported to increase transporter substrates’ AUC ≥1.5 to 
≥2 fold, and thus fall into the category of moderate inhibitors. They are to be advised 
used with caution (FDA’s Web site on Drug Development and Drug Interactions 
http://www.fda.gov/Drugs/DevelopmentApprovalProcess/DevelopmentResources/Dr
ugInteractionsLabeling/ucm080499.htm. See Appendix 11 for detailed listings)  
• 
It is necessary to avoid the concomitant use of drugs that prolong the QT interval 
prior to (approximately 5 half-lives of the concomitant drug) and during study 
enrollment.   These drugs may include antibiotics, fluoroquinolones, macrolides, 
and anti-arrhythmics, angina relieving drugs, antipsychotic drugs, antifungal drugs, 
antimalarial drugs, antihistamines, gastrointestinal antiemetic and promoting drugs, 
and antidepressants, etc.

• 
Subjects should be advised to restrict use of proton pump inhibitors (PPIs). 
Subjects should be encouraged to avoid concomitant administration of rivoceranib 
with acidic modifiers or H2 blockers. If these concurrent medicines are needed, 
they should be taken 5 hours after the studied drug administration. For other 
prohibited concurrent medicines please refer to Appendix 11. 
5.3.1.4. Drugs Used Cautiously for Subjects Given Sorafenib During the Study 
Rifampicin, one strong CYP3A4 inducer, once per day at the dose of 600 mg in healthy 
volunteers, for consecutive 5 days, and single dose of oral sorafenib 400 mg, can lead 
to decrease of average AUC of sorafenib by 37%. Therefore, strong CYP3A4 inducers 
(such as dexamethasone, phenytoin, carbamazepine, rifampicin, phenobarbital, 
rifapentine, Hypericum perforatum L [also known as St John's-wort], etc.) should be 
avoided as concomitant medications; they may accelerate metabolism of sorafenib and 
decrease the concentration of sorafenib. 
The combined use of sorafenib with neomycin may lead to decreased bioavailability of 
sorafenib by above 50%.  
In addition, investigators can refer to the label of sorafenib tosylate tablets and combine 
with clinical practice for more detailed descriptions of the drugs prohibited or used 
cautiously for such subjects during the study.  
5.3.2. 
Permitted Concomitant Medications and Treatments During the Study 
5.3.2.1. Antiviral Treatment 
Subjects infected with HBV and HCV must receive antiviral therapy according to 
local standards. Antiviral therapy is recommended as below:  
Subjects with HBV infection can continue the original antiviral therapy if HBsAg is 
positive and they have started antiviral therapy and achieved satisfactory control of 
virus (HBV-DNA <500 IU/mL) prior to inclusion in the study; subjects with suboptimal 
viral control are recommended to switch to other standard anti-HBV medication (e.g., 
Entecavir) as recommended by local guidelines, and subjects can be enrolled when 
HBV-DNA is <500 IU/mL; subjects with newly discovered HBV infection in screening 
period can start standard anti-HBV treatment as recommended by local guidelines (e.g., 
Entecavir) immediately and can be enrolled when HBV-DNA is <500 IU/mL. 
Subjects with HCV infection, if HCV-RNA is positive, subjects must receive antiviral 
therapy in accordance with the local standard guideline on diagnosis and treatment of 
hepatitis C.  
5.3.2.2. Steroids 
Local use of steroids is allowed, for example, topically external use, eye, nasal cavity, 
intra-joint and inhalation; corticosteroids for epinephrine replacement therapy are 
allowed; corticosteroids for treatment of adverse reactions are allowed; transient use of 
steroids for prevention and treatment of allergic reactions (prevention of allergy to 
contrast agents, or treatment of other allergic reactions) are allowed.

5.3.2.3. Other Systemic Therapies 
During the treatment period, subjects should be given the best supportive treatment. 
The original hormone replacement therapy is allowed. Bisphosphonate for treatment of 
bone metastasis is permitted.  
5.3.2.4. Palliative Local Treatment 
Palliative therapy for local non-target lesions causing obvious symptoms is allowed, for 
example, bone pain; local radiotherapies or surgery and management of pleural effusion 
and ascites can be considered, however, the following conditions must be met:  
• 
These lesions are known to be present at enrollment;  
• 
Progression of disease must be judged by investigators, for subjects who need local 
therapy due to deterioration of symptoms during the study;  
• 
Subjects with progression of disease must meet the criteria for treatment beyond 
progression (see Section 6.6 for the details);  
• 
The lesions for local therapy cannot be target lesions;  
• 
Subjects should interrupt the dose of investigational product until the end of 
recovery period of palliative therapy, whilst receiving palliative local therapy.  
It is advisable to discuss with the sponsor prior to the start of palliative local therapy. 
The content of palliative therapy should be recorded carefully in eCRF and medical 
record, including the date, sites of treatment, therapeutic methods and dosage, adverse 
reactions, and do on.  
5.3.3. 
Surgery or Palliative Radiotherapy 
Any surgery or palliative radiotherapy should have theoretical basis and necessity 
during the study. At the interval between the treatment and use of investigational 
products, recovery that has no effect on the wound and search for the reason of unknown 
hemorrhage must be performed as much as possible. In accordance with the label of 
rivoceranib, it is advised to interrupt the dose of rivoceranib prior to the operation to 30 
days and after the operation. It is recommended in the label of sorafenib that the time 
of dose interruption of sorafenib will be based on the type of operation and status of 
wound healing and depend on clinician’s specific judgment. Besides that, it is 
recommended to interrupt the dose of study drugs at least 14 days prior to, during and 
at least 14 days after palliative radiotherapy, in this protocol, the dose resumption in the 
subjects receiving surgery depends on the clinical evaluation of wound healing and 
postoperative recovery.

STUDY PROCEDURES 
The utmost efforts will be made to ensure all the tests and procedures required in the 
protocol go as planned. However, unexpected things may happen sometimes and be 
beyond investigator’s control, making it difficult to test. In these cases, the investigator 
will take all steps necessary to ensure the safety and interests of the subject. When one 
test required in the protocol can not be performed, investigators need to record the

reason. In addition, the study team need to be informed of the accidental situation in 
time.  
6.1. 
Screening Period 
The screening period begins with the signing of the informed consent form and ends 
with the randomization or screening failure. Termination of this study after signing the 
informed consent form and prior to randomization will be regarded as screening failure. 
Subjects with screening failure can be re-screened. They must sign the informed 
consent form again, re-register and obtain a new subject number at the re-screening. 
Subjects can only be re-screened once.  
Subjects must sign the informed consent form before performing any screening 
procedure specified in this study. In case routine radiological evaluation has been 
performed for tumors prior to the signing of the informed consent form, computed 
tomography (CT), magnetic resonance radiological (MRI) or bone scan does not need 
to be repeated in screening period as long as they are completed within 28 days prior to 
the start of study drug (42 days prior to start of study drug is acceptable for bone scan), 
and meet the requirement for radiological evaluation in this study.  
Unless otherwise noted, collection of the following data should be completed within 
28 days prior to the start of study drug:  
• 
Obtain the informed consent form signed by the subject; 
• 
Assign subject number (subjects will be assigned a unique number in the study: the 
subject number reflects the numbering of study sites and numbering of subjects 
within the same study site; the numbering of subjects shall be in accordance with 
the sequence in which the subjects sign the informed consent form, for example, 
001, 002, 003, etc.); 
• 
Collect demographic characteristics; 
• 
Collect medical history (including history of tumor and past medical history, see 
the SCHEDULE OF ACTIVITIES for details);  
•

refer to the laboratory manual. If tumor sample is not accessible in special case, it 
can be discussed with Sponsor on a case-by-case basis); 
• 
Collect concomitant medications/therapies;  
• 
Collect AE;  
• 
Tumor radiological evaluation: the radiological evaluation prior to the signing of 
informed consent form and within 28 days prior to the first dose is acceptable, and 
will be performed based on RECIST v1.1 (evaluated by investigator and BIRC), 
mRECIST (evaluated by BIRC only) and imRECIST (evaluated by investigator 
only). All the measurable and evaluable tumor lesions should be evaluated and 
recorded, including enhanced CT/MRI scan of thorax, abdomen, pelvis and site of 
lesions, brain enhanced MRI or enhanced CT scan (excluding intracranial 
metastasis). Thoracic plain CT scan and abdominal, pelvic and brain MRI can be

examination of reactive capillary endothelial proliferation needs to be performed 
on the experimental arm; 
• 
Vital signs (performed after sitting still for 5 minutes): including temperature 
(whenever possible, the same method of measurement should be used throughout), 
blood pressure, pulse rate and respiratory frequency;  
If dose delay occurs, required examination during study treatment need to be performed 
as planned or more frequently if clinically indicated. Echocardiography and blood HCG 
test can be monitored at any time, if necessary. Also, in accordance with RECIST v1.1 
(investigator and BIRC evaluation), mRECIST (only for BIRC evaluation) and 
imRECIST (only for investigator evaluation), all evaluations during the treatment 
period, with randomization as baseline, will be performed once every 8 weeks (56 days) 
±7 days in the first 48 weeks, once every 12 weeks (84 days) ±7 days afterwards, and 
additionally performed when clinically indicated. When there is no BIRC determined 
progression of disease (according to RECIST v1.1), tumor evaluation should be 
continued, regardless of discontinuation of study treatment, unless death, withdrawal of 
informed consent, start of subsequent antitumor therapy or termination of study by the 
sponsor, whichever comes first; the evaluation includes the enhanced CT/MRI scan of 
thorax, abdomen, pelvis and site of lesions. Thoracic plain CT scan, abdominal and 
pelvic MRI can be performed in case of allergy to the contrast agent for enhanced CT; 
cranial CT/MRI and bone scan can be performed only when clinically indicated. 
Throughout the study, each subject must use the same procedure for radiological 
examination. Investigators must review the results prior to the next cycle of therapy. 
The subjects who have achieved remission (complete remission or partial remission) 
for the first time need to be confirmed by the next scheduled evaluation or repeated 
evaluation ≥ 4 weeks after the first evaluation.  
Subjects with BIRC determined progression (according to RECIST v1.1) can continue 
to use SHR-1210 monotherapy or combination with rivoceranib (experimental arm) or 
sorafenib (control arm) if investigator assess they meet the criteria defined in 
Section 6.6.  
Upon approval of protocol V6.0, disease progression will only need to be confirmed by 
investigator per RECIST v1.1.

Follow-up Period 
Follow-up period is initiated when the end-of-treatment visit is completed. 30 days (±7 
days) after the last dose of study drug, subjects must return to the study center for safety 
follow-up and complete the following parameters for safety evaluation, regardless of 
initiation of new antitumor therapy. The telephone follow-up will be performed 60 days 
(±7 days) and 90 days (±7 days) after the last dose of study drug, only the survival status, 
subsequent antitumor therapy, concomitant medication/therapy and AEs/SAEs within 
the timeframe specified in the protocol need to be collected.  When developing a 
safety follow-up plan, ensure that the visit is scheduled within the safety follow-up 
period (for the experimental arm, 90 days after the last study dose of SHR-1210 or 30 
days after the last study dose of rivoceranib (whichever is longer); for the control arm, 
it is after 30 days after the last study administration.) If the date of the previously 
completed end- of- treatment visit has exceeded the safety follow-up period, there is no 
need to schedule the safety follow-up visit.  
For the subjects in experimental arm, if the date of completed end-of-treatment visit has 
exceeded the first safety follow-up (30 days after the last dose), but the safety follow-
up period has not been exceeded, the subject does not need to go to the site for safety 
follow-up visit, and 1-2 telephone visits can be scheduled during the safety follow-up 
period. In this case, ensure that the interval between visits should not exceed 44 days, 
and a telephone visit should be conducted at the time point of the safety follow-up 
period. 
The following will be performed at safety visit at the study center: 
• 
Subject self-assessed outcomes: The EORTC QLQ-C30, QLQ-HCC18 and EQ-
5D-5L questionnaires should be completed prior to any other clinical evaluation in 
the clinical center during the first safety follow-up period (30 days (±7 days) after 
the last study dose);

When SHR-1210 is interrupted for longer than 30 days and finally is confirmed to 
be unable to resume, for this situation, the subject is required to come for a site visit 
and collect blood sample immediately when investigator confirms the subject is 
permanently terminated SHR-1210 treatment. If the subject has started new anti-
tumor therapy, it’s not necessary to collect the immunogenicity blood sample at 30

After the end of safety follow-up, the subjects will enter survival follow-up period. First 
survival follow-up will be performed 30 days (±7 days) after last safety follow-up. 
Investigators must follow up subject’s survival every 30 days (±7 days), until death, 
loss of follow-up, termination of study by the sponsor or reaching other criteria for end 
of study, whichever comes first. Investigators can inquire the subject, his/her family 
members or local physician via phone, collect subject’s survival information (death and 
reason of death) and data on other tumor therapies after the end of study treatment. The 
data on each survival follow-up needs to be recorded in detail in the original medical 
record. 
Subjects who end study treatment for toxicity or other reasons with no radiological 
progression observed still need to receive radiological evaluation according to the 
original frequency, until progression of disease or start of other antitumor therapy 
(except for traditional Chinese medicine), the radiological evidence on PD should be 
obtained from such subjects as much as possible.  
All the treatment-related toxicities must be followed up until they are resolved, 
recovered to baseline or considered as irreversible. AE should be reported and recorded 
according to the requirement during safety follow-up.  
6.5. 
Unscheduled Visits 
For unscheduled visits (e.g., due to AEs) that occur or are needed before the end of 
study, the following items should be recorded: 
• 
Visit date;  
• 
Reason for visit;  
• 
Concomitant medications/therapies (within the collocation period specified in the 
protocol); 
• 
AEs (within the collocation and follow-up period specified in the protocol);  
•

any);  
• 
Whether the subject can continue or resume study treatment, if yes, record the dose 
administered.  
6.6. 
Treatment Beyond Progression 
If the subject has progression confirmed by BIRC as defined per RECIST v1.1, he/she 
still can continue SHR-1210 alone or combined with rivoceranib (experimental arm) or 
sorafenib (control arm) when he/she can still clinically benefit from and tolerate study 
treatment, as evaluated by investigators. Upon approval of Protocol v6.0, disease 
progression will be confirmed by the investigator per RECIST v1.1. Subjects may 
continue on study treatment beyond the time of investigator-confirmed disease 
progression, at the discretion of the investigator if the subject is perceived to be 
experiencing clinical benefit.

Criteria on Post-Progression Continuation of SHR-1210 Alone or 
Combined with Rivoceranib in Subjects in Experimental Arm 
A part of subjects receiving immunotherapy can still clinically benefit following 
radiological progression. Although the tumor is enlarged, obvious necrosis or 
degeneration can appear inside the tumor, decreased density inside the tumor foci can 
be shown on CT, it is generally considered that the subject may benefit under this 
circumstance. After progression of disease as defined per RECIST v1.1, and confirmed 
by BIRC subjects meeting all of the following criteria may continue with the study 
treatment until there is no longer benefit from the treatment. Subjects who continue the 
dose following PD will receive periodic visit and efficacy evaluation according to the 
visit schedule specified in the trial. Disease progression will be confirmed by the 
investigator per RECIST v1.1 upon approval of Protocol v6.0; other procedures and 
criteria remain unchanged. 
• 
Investigators judge continuation of study treatment meets the optimal benefit for 
the subject, and the subject does not need to start other antitumor therapy 
immediately;  
• 
The subject can tolerate study treatment;  
• 
Stable ECOG-PS score (≤1);  
• 
No significant clinical symptom/sign of progression of disease, including change 
in laboratory examination parameters;  
• 
Non-rapid progression of disease and progression not involving major organs/sites 
(e.g., spinal cord compression);  
• 
The study treatment can be continued upon the review and approval by the medical 
monitors from the sponsor.  
6.6.2. 
Criteria on Post-Progression Continuation of Sorafenib Treatment in 
Subjects in Control Arm 
The growth of HCC can be possibly inhibited with continuation of the therapy in a part 
of subjects receiving sorafenib after radiological progression, which makes subjects 
clinically benefit. Thus, the subjects meeting all of the following criteria are allowed to 
continue sorafenib treatment after BIRC-confirmed disease progression defined by 
RECIST v1.1 in this study until there is no more benefit from the treatment, disease 
progression will be at the investigator’s confirmation per RECIST v1.1 upon approval 
of Protocol v6.0, other procedures and criteria remain unchanged:  
• 
Investigators judge continuation of sorafenib treatment meets the optimal benefit 
for the subject, and the subject does not need to start other antitumor therapy 
immediately, including but not limited to the second-line Regorafenib;  
• 
The subject can tolerate sorafenib treatment;  
• 
Stable ECOG-PS score (≤1);  
• 
No significant clinical symptom/sign of progression of disease, including change 
in laboratory examination parameters;

• 
Non-rapid progression of disease and progression not involving major organs/sites 
(e.g., spinal cord compression);  
• 
The study treatment can be continued upon the review and approval by the medical 
monitors from the sponsor.  
6.6.3. 
Other Precautions for Post-Progression Continuation of Treatment 
The clinical benefit evaluation must take clinical exacerbation, continued benefit from 
the treatment into consideration. Investigator should discuss with the sponsor about the 
decision on post-progression continuation of treatment, as judged by investigators.  
If a decision is made that the subject needs to continue study treatment following 
progression, the subject should be treated, evaluated and followed up as required in the 
protocol.  
The subjects who continue the treatment after PD must be sufficiently informed and 
sign the informed consent form for post-PD continuation of treatment: possible 
alternative therapies, potential risks with continuation of the treatment.  
If the subject terminates the treatment for a global deterioration of health status and has 
no objective evidence on progression of disease, the progression will be reported as 
symptomatic deterioration. Every effort should be made to obtain the objective 
evidence on progression in these subjects after termination of the study treatment (e.g., 
radiological confirmation).  
6.7. 
Study Extension Phase 
The purpose of the extension phase is to continue to provide access to study drugs for 
subjects who are still on study treatment and still derive clinical benefit at the time of 
end of study. It’s a post-trail treatment access phase. Upon initiation of the extension 
phase, the Sponsor considers the safety and efficacy profile of the experimental 
treatment regimen within this study to have been sufficiently established and data 
analysis required for regulatory purposes to have been completed. The Sponsor will 
notify the sites when will the study enter the extension phase. 
In the extension phase, subjects randomized in the experimental arm will continue on 
SHR-1210 in combination with rivoceranib, and subjects randomized in the control arm 
may have the option to crossover to receive experimental treatment and the decision 
made is upon investigator’s clinical judgment. Subjects who are not eligible to 
crossover experimental treatment per investigator clinical judgment can continue on 
sorafenib treatment. Sorafenib can be sourced either locally or centrally which can 
comply with the local regulatory and ethics requirement. 
Subjects will continue to receive study treatment until they are no longer benefiting 
from treatment as assessed by investigator’s clinical judgment. The extension phase 
will continue until the last subject receives the last dose of study drug (expected 
Jan.2025, take the actual occurrence as the standard). Subjects are to undergo periodic 
safety and tumor assessment. The frequency of these assessments during the extension 
phase are to be performed per local standard of care. The investigator should ensure site 
visits occur frequently enough and adequate assessments. Investigator may also refer to

the protocol to ensure the periodic visits, tumor assessment and safety management if 
needed.  
In order to collect important safety information for subjects during the extension phase, 
SAEs and pregnancy will continue to be collected. See Section8.3, 8.5 and APPENDIX 
12. 
The study clinical database will be closed at the initiation of the extension phase. 
Important safety information collection in the extension phase will be captured in the 
safety database. 
The schedule of activities for extension phase is presented in APPENDIX 12.  
Subjects who continue on study treatment at the time of extension phase initiation, will 
undergo the end of study treatment visit and perform all the study procedures as the 
protocol required. Subjects who had discontinued study treatment but not yet completed 
the follow up visits (i.e., safety follow up) at the time of extension phase initiation (e.g., 
subject just completed first safety follow up), will undergo the final safety follow up 
visit.  
The time of extension phase initiation may occur at different time points for study sites 
because of different processes at sites. Before extension phase, study sites need to 
ensure that all the data occurring prior to extension phase have been captured into CRFs, 
particularly for safety and survival information. In addition, for the subjects who are 
continuing to receive study treatment, the end of study treatment and end of study page 
in CRFs should be captured as well before entering into extension phase (detailed 
instruction for EOT and EOS page in CRFs for extension subjects. Refer to CRF 
completion guideline). If a scheduled visit occurred within 7 days before the time of 
extension phase initiation or the relevant examinations for end of treatment visit were 
completed within 7 days, these study procedures would not be necessary to be repeated 
on EOT.  
Site monitoring visits will occur at a reduced frequency but must be frequent enough to 
ensure adherence to GCP, study drug accountability, reporting of SAEs and pregnancy.  
During the extension phase, no data are to be entered into CRFs. Study central 
laboratory samples are not to be obtained (e.g., PK, ADA sampling), and radiographic 
images from the site are not to be submitted to BIRC.

EVALUATION 
7.1. 
Efficacy Evaluation 
The efficacy endpoints include: 
• 
Overall survival time (OS): defined as the time from randomization to death for 
any cause.  
As well as the following efficacy endpoints evaluated by the BIRC or investigator based 
on Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1), modified 
RECIST (mRECIST) and immune-modified RECIST (imRECIST):

HENGRUI CONFIDENTIAL 
113 
• 
Progression-free survival (PFS): defined as the time from the date of randomization 
to the first occurrence of radiological progression by tumor image evaluation or 
death, whichever comes first, evaluated by the BIRC or investigator based on 
RECIST v1.1, mRECIST or imRECIST. (Radiological progression based on 
imRECIST not considered a PFS event if subsequent assessment evaluated as a 
response or stable after ≥ 4 weeks.)  
• 
Time to progression (TTP): defined as the time from the date of randomization to 
radiological progression of disease, evaluated by the BIRC or investigator based 
on RECIST v1.1, mRECIST or imRECIST. (Radiological progression based on 
imRECIST not considered a TTP event if subsequent assessment evaluated as a 
response or stable after ≥ 4 weeks.) 
• 
Objective response rate (ORR): defined as the percentage of subjects with complete 
response (CR) or partial response (PR) evaluated by the BIRC or investigator based 
on RECIST v1.1, mRECIST or imRECIST. (In respect of ORR based on 
imRECIST, CR and PR can occur after radiological progression). 
• 
Disease control rate (DCR): defined as the percentage of subjects with complete 
response, partial response or stable disease (SD) ≥ 8 weeks evaluated by the BIRC 
or investigator based on RECIST v1.1, mRECIST or imRECIST. (In respect of 
DCR based on imRECIST, CR PR and SD can occur after radiological progression). 
• 
Duration of response (DoR): defined as time from the date of first record of 
objective response (CR or PR) to the first occurrence of radiological progression 
or death, whichever comes first, evaluated by the BIRC or investigator based on 
RECIST v1.1, mRECIST or imRECIST. (Radiological progression based on 
imRECIST not considered a PD event of DoR if subsequent assessment evaluated 
as a response or stable after ≥ 4 weeks.). 
• 
Best overall response (BOR): defined as the best response parameter between the 
date from randomization to objectively recorded progression or subsequent 
antitumor therapy, whichever comes first. For subjects with no progression or 
subsequent antitumor therapy documented, BOR will be determined based on all 
the response evaluation results. (The BOR based on imRECIST is defined as the 
best response between the date of randomization and the initiation of subsequent 
antitumor therapy or during the entire study period). 
7.2. 
Tumor Radiological Evaluation 
7.2.1. 
Tumor Evaluation Based on RECIST v1.1, mRECIST and imRECIST 
RECIST v1.1 (investigator and BIRC evaluated), mRECIST (only BIRC evaluated) and 
imRECIST (only investigator evaluated) will be used for evaluation of tumor response 
in this study, see APPENDIX 2 for the evaluation criteria. 
The tumor evaluation in screening period (at baseline) should include the enhanced 
CT/MRI scan of thorax, abdomen and pelvis. CT scan requires intravenous contrast 
agent and will scan the whole liver area, at least including 1) hepatic arterial phase and 
2) portal venous phase. Enhanced MRI can be used in case of contraindications for CT 
contrast agent. The enhanced MRI of the whole liver should at least include 1) hepatic 
arterial phase and 2) portal venous phase. Cranial enhanced CT or enhanced MRI has

to be performed at baseline as well. Systemic bone scan should be performed for 
subjects with known bone metastasis or suspected bone metastasis (exempted in case 
bone scan is performed within 42 days prior to first administration), the bone lesions 
need to be evaluated and followed up after treatment. If clinically indicated, tumors at 
other sites can be evaluated. 
Provision on selection of target lesions: no more than 2 target lesions in each organ, and 
the total number of lesions is not more than 5, more organs involved in tumors should 
be covered as far as possible. At baseline, the number and location of the target lesion, 
the major diameter of each target lesion (except lymph node) and the minor diameter 
of lymph node lesion, as well as the sum of diameters of all lesions should be recorded.  
The baseline evaluation and post-treatment efficacy evaluation should be performed 
using the same method and by the same investigator as far as possible. Following 
randomization, the tumor evaluation will be performed once every 8 weeks (56±7 days) 
in the first 48 weeks, and once every 12 weeks (84±7 days) afterwards. In the absence 
of a BIRC determined progression of the disease (according to RECIST v1.1), tumor 
evaluation should be continued, regardless of whether the subject has terminated the 
study, until the subject dies, withdraws the informed consent, initiates subsequent anti-
tumor therapy or terminated the study by sponsor, whichever comes first. Tumor 
evaluation during treatment includes enhanced CT/MRI scan of thorax, abdomen, 
pelvis and site of lesions; thoracic plain CT scan plus abdominal and pelvic enhanced 
MRI can be performed if the subject is allergic to the contrast agents for enhanced CT; 
cranial enhanced CT/MRI and bone scan can be performed only when clinically 
indicated. Each tumor evaluation must cover all the target lesions, and all the non-target 
lesions if there are no special circumstances.  
Further guidance and recommendations on image acquisition are provided in the Image 
Acquisition Guidelines. 
When clinically indicated, investigators can perform unscheduled tumor evaluation. 
Throughout the study, each subject must use the same procedure of radiological 
examination. Investigators must review the results prior to the next cycle of therapy. 
The subjects who have achieved response (complete response or partial response) for 
the first time need to be confirmed through the next scheduled evaluation or repeated 
evaluation ≥ 4 weeks after the first evaluation.  
When the subject develops disease progression as assessed by the investigator 
according to RECIST v1.1, the investigator is required to submit radiological data 
immediately to BIRC; if BIRC assessed it as non-disease progression according to 
RECIST v1.1, the study drug treatment should be continued for the subject and tumor 
radiological evaluation should continue; if BIRC confirms disease progression 
according to RECIST v1.1, the investigator needs to assess whether the subject still has 
clinical benefit, and if the subject is still considered to have clinical benefit and meets 
the criteria for continued treatment after progression of the disease (see Section 6.6), 
the subject may continue to receive study medication and continue the efficacy 
assessment at the original planned frequency. 
Tumor radiological assessment will continue until the occurrence of disease progression 
confirmed by BIRC according to RECIST v1.1 criteria or study treatment

115 
discontinuation, whichever occurs later. Subjects who discontinue treatment for reasons 
other than BIRC-confirmed disease progression (according to RECIST v1.1) will also 
continue with regular follow-up by tumor radiological assessments after treatment is 
completed. Before BIRC confirms the disease progression according to the RECIST 
v1.1 criteria or the treatment is discontinued, if the subject withdraws the informed 
consent, other anti-tumor treatment has begun (except for traditional Chinese medicine), 
or the subject dies, there is no need to continue the radiological evaluation. If the subject 
does not meet the above criteria for stop radiological assessment, the efficacy 
evaluation of the three efficacy evaluation criteria (RECIST v1.1, mRECIST, 
imRECIST) needs to continue even if the disease progression under certain efficacy 
evaluation criteria occurs.  
Once progressive disease occurs, a physical examination of the subject and radiological 
confirmation is required at any times, rather than waiting for the next planned 
radiological examination. If the unplanned radiological findings do not meet the 
RECIST V 1.1 criteria of progressive disease, follow-up examinations should still be 
performed on the original date for the next radiological examination, unless the next 
planned examination is less than 14 days of this one.  
If there has not been any disease progression confirmed by a radiological examination 
when the subject is about to withdraw from the study, it is recommended that a 
radiological examination be performed in time before the withdrawal (if the time from 
the last radiological examination to the withdrawal is ≤ 4 weeks, additional radiological 
examination will not be required at the time of withdrawal). 
Upon approval of protocol v6.0, radiographic images from the sites are not to be 
submitted to BIRC, therefore, disease progression confirmation by BIRC is not needed.

Collection Time of Blood Samples 
SHR-1210 combined with rivoceranib experimental arm: 
Pre-dose sampling: on Day 1 from Cycle 1 to Cycle 4 (C1D1, C2D1, C3D1, C4D1); 
and on Day 1 of every 3 cycles afterwards (The time point for sample collection will be 
within 0.5 hours prior to rivoceranib administration). Collect once at 30 days (±7 days) 
after the last dose of SHR-1210. When SHR-1210 is interrupted for longer than 30 days 
and if is confirmed to be unable to resume, the subject is required to come for a site 
visit and collect blood sample immediately. If the subject has started other anti-tumor 
therapy, it’s not necessary to collect the immunogenicity blood sample at 30 days (±7 
days) after the last administration of SHR-1210. If SHR-1210 and/or rivoceranib is 
temporarily interrupted, pre-dose immunogenicity and PK sample will be collected on 
schedule. If only rivoceranib is interrupted at time point mentioned above, blood sample 
will be collected within 0.5 hours prior to SHR-1210 administration. The above samples 
will be used to measure the blood concentration and immunogenicity of SHR-1210, and 
the plasma concentration of rivoceranib in the C2D1-C4D1 samples. The exact time of 
the previous administration of rivoceranib will be collected for C2D1, C3D1 and

C4D1(the subject is required to provide it).  
ECG blood sampling: ECG examination is performed 2.5 hours (±1 hour) after the end 
of the rivoceranib administration, and blood is collected within 15 minutes after the 
ECG examination on the first day from Cycle 1 to Cycle 4. If rivoceranib is 
discontinued, blood samples within 15 minutes of ECG will not be collected. Plasma 
concentrations of rivoceranib will be measured in the above samples. 
The actual sampling time and the time for the administration of rivoceranib and SHR-
1210 will be recorded on the day of sampling. (refer to BLOOD SAMPLE 
COLLECTION TABLE). 
7.4.2. 
Processing and Storing of Blood Samples 
Approximately 6 mL venous blood samples for measuring the immunogenicity and 
concentration of SHR-1210 will be collected at each timepoint mentioned above. 
2mL venous blood samples for measuring the plasma concentration of rivoceranib will 
be collected at each time point mentioned above.  
The blood samples mentioned above will be transferred into aliquots and then be placed 
in a low temperature freezer until delivered to the central laboratory for detection. 
Detailed procedures and the shelf life are described in the Laboratory Manual. 
7.4.3. 
Delivery of Blood Samples 
The test tube samples will be delivered firstly using dry ice preservation. The back-up

Patient Reported Outcomes (PRO) 
All the subjects will complete EORTC QLQ-C30, EORTC QLQ-HCC18 and EQ-5D-
5L questionnaires prior to the administration of study drug and conduction of any other 
study evaluation at the clinical center from Day 1 of Cycle 1, then repeat the above 
procedure on Day 1 of every cycle. In addition, all subjects will be assessed by above-
mentioned questionnaires in the visit of end-of-treatment and first safety follow-up. 
Questionnaires for PRO evaluation should be validated and in subjects’ local language. 
The questionnaires will be paper-based in this study.  
Questionnaires should be completed prior to initiation of any pertinent study visit which 
involves other study activities (including study treatment) and contact with the 
investigator, to ensure that the results are not influenced by the interaction between the 
subject and the investigator. Provide subjects with a quiet place and advise them to 
complete within 30 minutes. The study site should make every effort to ensure that a 
complete questionnaire is obtained from each subject at each scheduled time point, so 
as to avoid any delay in clinical evaluations. 
If there are privacy requirements for filling out questionnaires in local regulations (e.g.,

if the questionnaire is not supposed to be seen by the clinical staff), the study site should 
make appropriate arrangements to ensure that the requirements are met as far as 
possible. 
7.5.1. 
EORTC QLQ-C30 and EORTC QLQ-HCC18  
EORTC QLQ-C30 is a core scale in the quality of life measurement questionnaire 
system for all cancer subjects that is systematically developed by European 
Organization for Research and Treatment of Cancer (EORTC), and used for 
measurement of quality of life in all the cancer subjects (for the common part). The 
questionnaire is comprised of 5 functional scales (somatic, role, cognitive, emotional, 
social), 4 symptom scales (fatigue, pain, nausea, vomiting), one global health status 
scale and several separate items (including dyspnea, anorexia and insomnia). This 
questionnaire consists of 30 multiple-choice questions.  
The specific module for different cancers is added on EORTC QLQ-C30, i.e., the 
specific scale for different cancers is formed, HCC module (EORTC QLQ-HCC18) is 
used in this study. The samples of EORTC QLQ-C30 (version 3.0)and EORTC QLQ-
HCC18 scales used in this study are seen in APPENDIX 8 and APPENDIX 9.  
In this study, EORTC QLQ-C30 and EORTC QLQ-HCC18 scales will be used to 
evaluate the quality of life (QoL), including health related quality of life (HRQOL) / 
general health state (GHS), physical functioning and role functioning, of subjects with 
advanced HCC who receive SHR-1210 combined with rivoceranib mesylate as a first-
line therapy versus those who receive sorafenib as a first-line therapy. The following 
endpoints are included:  
• 
TTD, defined as time from randomization to first deterioration, as determine by 
following subscales of EORTC QLQ-C30 (decreased by ≥ 10 points from baseline), 
at least maintained for two consecutive time points, or maintained for one-time 
point but death in the following 4 weeks (for any reason):  
• 
HRQOL/GHS 
• 
Physical functioning 
• 
Role functioning 
• 
Average scores and average change from baseline in all the subscales of EORTC 
QLQ-C30 and EORTC QLQ-HCC18 (by cycle);  
7.5.2. 
EQ-5D-5L 
In this study, the health utility index in European five-dimensional health scale (EQ-
5D-5L) and VAS score will be used to evaluate the health status of subjects with 
advanced HCC who receive SHR-1210 combined with rivoceranib mesylate as a first-
line therapy versus those who receive sorafenib as a first-line therapy, so as to generate 
the utility score for health economic assessment. 
EQ-5D is a validated and reliable, self-report-based measurement developed by Euro 
QoL Group to evaluate health- related quality of life. It is a universal scale and currently 
includes two versions, EQ-5D-3L and EQ-5D-5L. The EQ-5D-5L version used in this

study includes the EQ-5D-5L descriptive system and EQ visual analogue scale (EQ-
VAS) (See APPENDIX 10 for a sample scale).  
The EQ-5D-5L descriptive system measures subject’s health state from 5 dimensions 
(5D): mobility, self-care ability, daily activities, pain/discomfort and anxiety/depression. 
Each dimension is further divided into 5 levels (5L): (1) no difficulty, (2) slight 
difficulty, (3) moderate difficulty, (4) serious difficulty, (5) extremely serious difficulty. 
Subjects will be asked to select the most appropriate level in each dimension according 
to their health status.  
EQ-VAS is a vertical visual scale in a length of 20cm. Its top is 100 points and 
represents “the best health state in mind”, whereas the bottom is 0 point and represents 
“the worst health state in mind”. Subjects will be asked to mark the point that best suits 
to their own health state on that day on the scale, that is, to score the overall health state 
on that day.  
EQ-5D-5L descriptive system combined with EQ-VAS can fully reflect the health state 
in the study population.

Before enrollment, subjects must be able to provide fresh or archived tumor tissue 
(formalin-fixed, paraffin-embedded [FFPE] tissue block or at least 5 unstained FFPE 
slides) for the immunohistochemical examination of PD-L1 expression level, so as to 
explore the relation between biomarkers and the efficacy of combination therapy. 
Biopsied specimen, such as the specimen biopsied with fine needle aspiration, cell 
smear from pleural effusion drainage and centrifugation or drilled biopsy are inadequate 
to review and evaluate biomarkers. The bone lesions without soft tissue component or 
decalcified tumor specimen are not acceptable. For fresh tumor biopsied specimen, the 
detailed description of its collection, handling, processing and shipment is provided in 
the Laboratory Manual.

ADVERSE EVENT REPORTING 
8.1. 
Adverse Events 
8.1.1. 
Definition 
AE is defined as adverse medical events that occur after the subject who receives a drug 
in clinical trial, but do not necessarily have a causal relationship with the treatment. 
Refer to Section 8.3 for details on the AE collection period. AE can be any undesirable 
and unexpected symptom, sign, laboratory abnormality or disease, including at least the 
following conditions: 
1) Aggravation of existing (prior to enrollment of clinical trial) medical 
conditions/disease (including exacerbation of symptoms, signs, laboratory 
abnormalities); 
2) Any new occurrence of AE: any adverse medical conditions newly occurred 
(including symptoms, signs, newly diagnosed diseases); 

Study Drug Number: SHR-1210 
Protocol Number: SHR-1210-III-310 
Version 6.0, 21 Sep 2022 
 
HENGRUI CONFIDENTIAL 
121 
3) Abnormal laboratory test or result of clinical significance. 
The investigator should carefully record any AE occurs in the subjects, including: the 
description of adverse event and all relevant symptoms, time of onset, severity, the 
correlation-ship with investigational drugs, duration, actions taken against the study 
drug, final outcomes and prognosis. 
The word “disease progression” should not be reported as an AE term as disease 
progression is an expected occurrence in the study population, except as described in 
8.2.3 section. When a disease progression occurs, the occurrence that confirms disease 
progression should be reported as an AE. For example, if the subject has epilepsy that 
is determined to be related with brain metastasis, epilepsy should be recorded as the AE 
term, rather than “disease progression” or “brain metastasis”. Progression of the disease 
being studied assessed by measurement of lesions on radiographs or other methods 
should not be reported as an AE. 
8.1.2. 
The Judgment Standard on Severity of AE 
Refer to NCI-CTC AE v4.03 grading criteria for AEs related drugs. Refer to the 
judgment criteria in Table 12 if any AE is unlisted in NCI-CTCAE v4.03. 
Table 12 
The Judgment Standard on Severity of AE 
Grade 
Clinical Description of Severity 
1 
Mild; without clinical symptoms or mild clinical symptoms; only with clinical or laboratory 
abnormalities; no treatment is required. 
2 
Moderate, requiring minimal, local or non-invasive treatment; age-appropriate limits in 
Activities of Daily Living (ADL); involving tools refer to cooking, shopping, calling, 
counting money, etc. 
3 
Severe conditions or serious medical symptoms but not life-threatening; leading to 
hospitalization or hospitalization prolonged; leading to disability; limited in self-care ADL. 
Daily self-care includes bathing, dressing, undressing, eating, going to the bathroom, 
medication, and so on, non-bedridden. 
4 
Life-threatening; emergency treatment is required 
5 
Leading to death 
 
8.1.3. 
Causality Assessment 
Collection of AE starts from the signing of informed consent, records are collected 
regardless of whether the event is related to the investigational drug, whether the subject 
is assigned to the experimental arm, or even whether the drug is used or not. Any 
discomfort or abnormal change in objective laboratory tests during the treatment should 
be recorded accurately. Meanwhile the severity, duration, management and outcome of 
the AE should be recorded. The investigator should determine the relationship between 
AE and study drugs, such as whether the occurrence of AE has relationship with a 
reasonable medication order, the properties of study drug, toxicological and 
pharmacological effects of study drug, subjects’ use of other concomitant drugs, 
subjects’ underlying diseases, medical history, family history and provocative and re-
provocative reactions, etc. The causality relationship between AE and study drug will

Protocol Number: SHR-1210-III-310 
Version 6.0, 21 Sep 2022 
 
HENGRUI CONFIDENTIAL 
122 
be assessed to be “related” or “unrelated” which are described in the following.   
Related: there is a rational relationship between AE and the study drug, the AE can be 
attributed to the study drug medically (pharmacologically or clinically).  
Unrelated: there is lack of rational relationship between AE and the study drug, and the 
AE can not be attributed to the study drug medically (pharmacologically or clinically), 
and/or there is other rational reason to explain it, such as underlying disease, 
complication, and concomitant medications.  
8.2. 
Serious Adverse Events 
8.2.1. 
Definition of SAE 
Serious adverse event (SAE) is defined as the medical events that require 
hospitalization or prolonged hospitalization, disability, limiting working ability, life-
threatening or death, and leading to congenital malformation during the clinical trial. 
Including the following medical events: 
• 
Events leading to death; 
• 
Life-threatening events (defined as the subject has is at risk of death at the time of 
the event); 
• 
Events requiring hospitalization or prolonged hospitalization; 
• 
Events that result in persistent or significant disability / incapacity / limiting 
working ability; 
• 
Congenital abnormalities or birth defects; 
• 
Other important medical events (defined as the event threatens the safety of the 
subject, or requires intervention measures for the prevention of any of the above 
outcomes). 
8.2.2. 
Hospitalization 
Adverse event which causes hospitalization (even less than 24 hours) or prolonged 
hospitalization should be considered as SAE. 
Hospitalization does not include the following: 
• 
Rehabilitation facilities 
• 
Nursing homes 
• 
Routine emergency room admissions (within 24 hours) 
• 
Same day surgeries (as outpatient/same day/ambulatory procedures) 
• 
Social reason (medial insurance reimbursement, etc.) 
Hospitalization or prolongation of hospitalization in the absence of a deteriorating 
adverse events will not be considered as SAEs. For example, 

Study Drug Number: SHR-1210 
Protocol Number: SHR-1210-III-310 
Version 6.0, 21 Sep 2022 
 
HENGRUI CONFIDENTIAL 
123 
• 
Admission for treatment of a preexisting condition without the development of new 
adverse events or worsening of the preexisting condition (e.g., for work-up of 
persistent pre-trial laboratory test abnormality); 
• 
Administrative admission (e.g., for yearly physical exam); 
• 
Hospitalization as per the trial protocol during the study (e.g., as required by the 
protocol); 
• 
Elective admission not associated with the aggravation of adverse events (e.g., 
elective surgery); 
• 
Predefined treatments or surgical procedures should be documented throughout the 
study program and/or in the baseline data of individual subject; 
• 
Admission exclusively for the administration of blood products. 
Diagnostic or therapeutic invasive (e.g., operation) and non-invasive procedures should 
not be reported as AE, but if the disease condition leading to the operation should be 
reported if it conforms to the definition of AE, e.g., acute appendicitis during the AE 
reporting period should be reported as AE; therefore, the appendectomy should be 
recorded as the treatment of the AE. 
8.2.3. 
Disease Progression and Death 
Disease progression is defined as the exacerbation of the subject caused by indications 
of the study drug, including radiological progression and progression of clinical 
symptoms and signs. New metastases relative to the primary tumor and the progression 
of the original metastases are both considered to be progressive disease. Events that are 
life-threatening, requiring initial or prolonged hospitalization due to symptoms and 
signs of disease progression, which can lead to persistent or significant disability / 
incapacity / limiting work ability are not reported as SAE. If there is any uncertainty 
about whether SAE is caused by the progression of disease, it should be reported as 
SAE.  
All cases of death that occur during the study period must be reported as SAEs, whether 
or not the subject has received other anti-tumor therapy (see Section 8.3). The word 
“death” should not be reported as an AE or SAE term, but as the outcome of the event; 
the AE that causes or contributes to the fatal outcome should be recorded as the single 
medical concept. If the cause of death is unknown and cannot be ascertained at the time 
of reporting, the AE or SAE should be recorded as “unexplained death”, if the cause of 
death later becomes available, "unexplained death" should be replaced by the 
established cause of death  
If death due to disease progression cannot be attributed by the investigator to a medical 
event, a Grade 5 “Tumor progression” should be recorded in the eCRF and reported as 
an SAE. Evidence that the death is due to disease progression (e.g., radiological changes 
suggesting tumor growth or progression, clinical deterioration associated with a disease 
process) should be provided by the investigator. 
8.2.4. 
Reporting Procedures of SAE 
In case of SAE, regardless of first report or follow-up report, the investigator must fill

in the “Clinical Trial Serious Adverse Event (SAE)/Special Interest Event (SIE) Report 
Form” immediately, sign and date it, report it to the sponsor within 24h after learning 
of it, and report it to relevant organizations in time as required by regulations.  
The detailed record content of SAE should include symptoms, severity, and association 
with investigational drugs, time of onset, time of treatment, measures taken, follow-up 
time and method as well as outcome. If the investigator considers that a SAE is not 
related to study drug while potentially related to the study conditions (e.g., termination 
of the original treatment or complications during the trial), the relationship should be 
described in detail in the narrative section of SAE report form. If there is a change in 
the severity of an ongoing SAEs or its relationship with the study drug, follow-up 
reports should be submitted immediately. If misinformation is considered to be present 
in the previously reported SAE, it can be corrected, withdraw or degraded in the follow-
up report, and reported in accordance with the SAE reporting procedures. 
The sponsor’s email to receive safety reports (SAE, SIE, pregnancy) in this study: 
hengrui_drug_safety@hengrui.com 
8.3. 
Collection and Follow-Up of AE/SAE 
The period for AE/SAE collection begins from the time that the subject provides 
informed consent, through and including 90 days after the last dose of SHR-1210 or 
30 days after the last dose of targeted anti-angiogenic therapy, whichever comes later. 
SAEs that occur after this period, if suspected to be related to study drug, should also 
be collected. See Table 13 for detailed requirements. An AE/SAE will be followed up 
until it is resolved, returns to the baseline level or ≤ Grade 1, or reaches a stable state, 
or until other reasonable time points (e.g., loss of follow-up, death). Every effort should 
be made to ensure the final outcome and definite causality assessment is obtained. 
Investigators should inquire about AE/SAE after the last visit at each visit and provide 
follow-up data in time according to the sponsor’s queries.  
For the AE/SAE that occurs after extension phase initiation, only SAE should be 
reported to Sponsor via email, and non-serious AE will not be collected. See Table 14 
for detailed requirements. See Section 错误! 未找到引用源。 for reporting 
requirement of pregnancy.

AEs of Special Interest 
For the AE of special interest (SIE) specified in the study protocol (as below), 
investigators need to fill in the “Clinical Trial Serious Adverse Event (SAE)/Special 
Interest Event (SIE) Report Form” within 24h after the event is known, and report to 
the sponsor. 
• 
≥ Grade 3 infusion reaction 
• 
≥ Grade 3 immune-related AE 
• 
AEs that meet the criteria defined in Section 8.4.1 (Liver Function Test [LFT] 
Abnormalities) 
8.4.1. 
Liver Function Test (LFT) Abnormalities 
Considering the specialty of abnormal liver function at baseline in HCC subjects, 
abnormal values in ALT and/or AST concurrent with abnormal elevations of TBIL that 
meet the criteria outlined below (i.e., meeting the criteria [1] and [2] for elevated ALT 
or AST and bilirubin as well as the criterion [3]) in the absence of other causes of LFT 
abnormalities should always be reported as SIEs.  
1) 
ALT or AST ≥ 3 × ULN (normal at baseline), ALT or AST ≥ 3 × baseline value 
(abnormally elevated at baseline) 
2) 
TBIL ≥ 2 × ULN (normal at baseline), TBIL ≥ 2 × baseline value (abnormally 
elevated at baseline) 
3) 
Excluding other causes of LFT abnormalities (e.g., disease progression, acute 
viral hepatitis, cholestasis, underlying hepatic disease, and concomitant 
medications with hepatotoxicity). 
Subjects should return to the study center as soon as possible after learning the abnormal 
results (preferably within 48 hours). Evaluation should include laboratory examination, 
detailed medical history and physical evaluation. 
Besides repeated measurement of AST and ALT, the laboratory examination should also 
include albumin, creatine kinase, total bilirubin, direct bilirubin, γ-glutamyl transferase,

PT/ INR, and alkaline phosphatase. Collection of detailed medical history should 
include history of alcohol, acetaminophen, soft drugs, various supplements, family 
history, occupational exposure, sexual behavior history, travel history, contact history 
with jaundice subjects, surgery, blood transfusion, hepatopathy or allergic disease 
history. Further examinations also include detection of acute hepatitis A, B, C and E as 
well as radiological examination of liver (e.g., biliary passage). 
8.5. 
Pregnancy 
If a female subject becomes pregnant during the clinical trial, the subject must 
discontinue the study drug immediately; if the partner of male subject becomes pregnant 
during the clinical trial, the subject can continue the clinical trial.  
For pregnancy of female subjects or partners of the male subjects during this study, 
investigators should fill in “Pregnancy Report/Follow-up Form in Hengrui Clinical 
Study”, and report to the sponsor within 24 hours after investigator awareness, and 
report to the ethics committee in time.  
The investigator should follow up the pregnancy outcome, until one month after 
delivery, and will report the outcome to Sponsor and Ethics Committee. 
If the outcome of pregnancy is stillbirth, spontaneous abortion, or fetal malformations, 
it should be considered as an SAE and be reported to Sponsor, regardless of causality. 
9. 
CLINICAL MONITORING 
In order to make sure the subject’s rights are protected, all the data should be reported 
accurately, completely and reliably. The trial should be conducted in accordance with 
currently approved protocol/revised protocol, ICH-GCP and appropriate regulations; 
clinical monitoring is needed for the study center. 
10. 
STATISTICAL ANALYSIS 
A statistical analysis plan (SAP) will be prepared to provide further details regarding 
the definition of analysis variables and analysis methodology to address all study 
objectives. The SAP will serve as a compliment to the protocol and where there is a 
discrepancy between the SAP and protocol, the SAP will supersede it. Any critical 
revision within the SAP of definition(s) or analysis method(s) for the primary endpoints 
will be included in a protocol amendment.  
10.1. Sample Size Determination 
Assuming a 1:1 randomization between sorafenib and SHR-1210+rivoceranib, and a 
median PFS time of 3.6 months for subjects in the sorafenib group and a median PFS 
time of 6 months for subjects in the combination group, 332 PFS events will be 
sufficient to detect a hazard ratio (HR) of 0.60 with 98% power based on Log-rank test 
at significance level of 0.005 one-sided. Similarly, assuming a median survival time of 
10.5 months for subjects in the sorafenib group and a median survival of 14.6 months 
for subjects in the combination group, 359 OS events will be sufficient to detect a 
hazard ratio (HR) of 0.72 with 85% power based on Log-rank test at significance level

127 
of 0.020 one-sided. Assuming an accrual period of 18 months, total duration of 36 
months and 19 months for the OS and PFS, respectively, and probability of subject loss 
be approximately 10% per 12 months and per 6 months for the OS and PFS, respectively, 
a sample size of 510 subjects will be enrolled for the study. Power and sample 
calculations were performed using EAST® 6.4.1. software package. 
10.2. Objectives and Statistical Hypotheses 
10.2.1. Primary Objectives and Statistical Hypotheses 
Objectives: To compare efficacy endpoints of OS and PFS evaluated by the BIRC based 
on RECIST v1.1 in 2 experimental arms (SHR-1210 in combination with rivoceranib 
versus sorafenib).  
Hypothesis: SHR-1210 in combination with rivoceranib prolongs OS compared to 
sorafenib. 
Hypothesis: SHR-1210 in combination with rivoceranib prolongs PFS (assessed by 
BIRC based on RECIST v1.1) compared to sorafenib. 
10.2.2. Key Secondary Objectives and Statistical Hypotheses 
Objective: To compare the ORR (assessed by BIRC according to RECIST) of SHR-
1210 in combination with rivoceranib to sorafenib 
Hypothesis: The ORR (assessed by BIRC according to RECIST v1.1) of SHR-1210 
combined with rivoceranib is superior to sorafenib. 
10.3. Analysis Populations 
• 
Intent-to-treat (ITT): This population will include all randomized subjects. Subjects 
will be included in the experimental arm to which they are randomized.  
• 
Safety Analysis Set (SS): This population will include all treated subjects who 
receive at least 1 dose of study treatment. For most subjects, this will be the 
experimental arm to which they are randomized. For subjects who take incorrect 
study treatment for the entire treatment period, safety data will be analyzed based 
on the treatment they actually receive.  
• 
Anti-drug Antibody (ADA) Analysis Set: This population will include all subjects 
who receive SHR-1210 in combination with rivoceranib and had at least 1 ADA 
measurement. 
• 
PK Analysis Set: This population will include all the subjects who receive PD-1 
antibody SHR-1210 combined with rivoceranib and who have at least one result 
for drug concentration at any time during the study. 
10.4. Statistical Analysis Methods 
10.4.1. General Method 
This is a parallel group, controlled study. All statistical tests, unless otherwise specified, 
will be analyzed by experimental arms and using the appropriate statistics according to 

Study Drug Number: SHR-1210 
Protocol Number: SHR-1210-III-310 
Version 6.0, 21 Sep 2022 
 
HENGRUI CONFIDENTIAL 
128 
the data type. Summary statistics for continuous variables will include the mean, 
standard deviation, median, and range (minimum/maximum). Categorical variables will 
be presented as frequency counts and percentages. Time-to-event variables will be 
summarized by Kaplan-Meier (K–M) medians and 95% CI. 
10.4.2. Subject Disposition 
The number of subjects enrolled, treated, discontinued and those with major protocol 
deviations will be counted. The primary reason for study drug and/or study 
discontinuation will be summarized according to the categories in the eCRF. The end 
of study status (alive, dead, withdrew consent or lost to follow-up) at the data cutoff 
date will be summarized.  
10.4.3. Demographics and Baseline Characteristics 
Demographic and other baseline characteristics will be summarized using descriptive 
statistics. Continuous variables include age, weight, vital signs, time since initial cancer 
diagnosis, and time since advanced/metastatic disease diagnosis; categorical variables 
include, gender, ECOG-PS score, geographical region, country, race, Child-Pugh 
classification, hepatitis virus, BCLC staging, metastatic site, and macrovascular 
invasion and/or extrahepatic spread status etc.  
10.4.4. Prior and Concomitant Medications 
Concomitant medications will be coded using the WHO Drug Dictionary drug codes. 
Prior and concomitant medications will be summarized and listed by drug and drug 
class. Prior medications will be defined as medications taken within 28 days of the first 
dose of study drug that were stopped prior to study drug administration. Concomitant 
medications will be defined as medications that 1) started before the first dose of study 
drug and were continuing at the time of the first dose of study drug, or 2) started after 
the first dose of study drug. Prior and concomitant medications will be listed. 
10.4.5. Primary Efficacy Endpoints Analyses 
The two primary endpoints for the study are OS and PFS (assessed by BIRC based on 
RECIST v1.1). For the PFS endpoint, there is one planned analysis, which is expected 
to occur when ~332 PFS events are observed ~19 months after first subject enrolled. 
For the OS endpoint, it will be evaluated in the following time points: when PFS is 
analyzed (approximately 19 months after first subject enrolled); when ~251 OS events 
(70% at ~23 months after first subject enrolled) and when 359 OS events are observed 
(at ~36 months after first subject enrolled).  
The hypothesis testing of OS and PFS will be evaluated by comparing SHR-1210 plus 
rivoceranib to sorafenib on their events in ITT using a stratified Log-rank test (based 
on randomization stratification factors). The hazard ratio (HR=SHR-1210 plus 
rivoceranib / sorafenib) and the corresponding 95% confidence interval (CI) will be 
estimated in a stratified Cox proportional hazard model with experimental arm and 
randomization stratification factors included in the model. Survival curves for each 
treatment group will be estimated using the Kaplan-Meier (KM) product-limit method. 
A 95% CI for median survival time will be estimated by Brookmeyer-Crowley method. 
The above analyses will be repeated without the stratification factors included in the 

Study Drug Number: SHR-1210

analysis. In case the proportional hazard is not valid, Wilcoxon test or RMST 
(Restricted Mean Survival Time) method may be performed for OS and PFS analysis. 
Detail of multiplicity control can be found in Section 10.4.12.  
Further detail, including censoring rules, will be provided in the SAP. 
10.4.6. Secondary Efficacy Endpoints Analyses 
Objective response rate (ORR) assessed by BIRC according to RECIST v1.1 will be 
analyzed as a key secondary endpoint when 70% OS events are observed. If both PFS 
and OS primary endpoints are positive, comparison between treatment groups in ORR 
by BIRC according to RECIST v1.1 will be performed using stratified Cochran-Mantel-
Haenszel (CMH) test. Difference in proportions for ORR and its 95% CI using normal 
approximation will be provided. Overall response rates and their corresponding 95% 
exact CIs will be calculated by Clopper-Pearson method for each treatment group. 
The other time-to-event endpoints will be estimated using the Kaplan-Meier (KM) 
product-limit method, unless specified. A 95% CI for median survival time will be 
estimated by Brookmeyer-Crowley method, if necessary.  
For other binary variables, stratified CMH test will be used and two-sided 95% CI for 
treatment difference will be calculated using normal approximation. 
Further elaborations will be provided in the SAP. 
10.4.7. Pharmacokinetics and Immunogenicity  
The incidence of ADA and the proportion of subjects with neutralizing active antibodies 
(Nab) in subjects treated with SHR-1210 in combination with rivoceranib will be 
summarized using descriptive statistics by experimental arm and by visit. ADA/Nab in 
combination with SHR-1210 concentration, safety, and efficacy will be summarized 
using descriptive statistics (see Section 10.4.8). Any other analysis methods will be 
elaborated in the corresponding analysis plan. 
The population PK, exposure-QTc analysis and exposure-response analysis will be 
performed and reported separately. 
10.4.8. Exploratory Endpoints Analyses 
The time to deterioration (TTD) of EORTC QLQ-C30 endpoints will be analyzed using 
similar method for the primary endpoint OS (stratified Cox model and K-M curve). The 
scores of other scales and the average change from the baseline will be summarized 
using descriptive statistics by treatment cycle. 
The correlation of the expression level of PD-L1 and proportion of strong expression 
of PD-L1 in tumor tissue with the efficacy of SHR-1210 combined with rivoceranib 
mesylate (including but not limited to ORR, OS) will be summarized using descriptive 
statistics. If necessary, an ad hoc analysis will be performed and results will be 
presented in a separate supplementary report.

Efficacy endpoints (e.g. BOR, ORR) and safety endpoints (e.g. immune-related adverse 
events (irAE), study drug-related AE with CTCAE grade ≥ 3, drug-related SAE) with 
SHR-1210 ADA/Nab status in experimental arm will be summarized using descriptive 
statistics. If necessary, a comparison of efficacy and safety will be performed according 
to the ADA status. 
PFS, TTP, ORR and DoR assessed by investigator based on imRECIST will be 
evaluated using the same analytical methods for the secondary endpoints. 
Other analytical methods for exploratory endpoints will be elaborated in the SAP. 
10.4.9. Handling of Missing Data 
Except for the special cases, the following rules will be applied to the missing date of 
the events. 
If the start date of the event is all missing, it will not be imputed. If the day is missing, 
but the year and month are consistent with the year and month of the study drug 
treatment, the day of the first study drug treatment will be used. Otherwise, the first day 
of the month will be used. If the day of end date is missing, but the year and month are 
consistent with the year and month of the end of study drug treatment, the day of 
end - of-treatment will be used. Otherwise, the last day of the month will be used. 
If the month and day of the event are missing, but the year of occurrence is consistent 
with the year of study drug treatment, the month and day of the first study drug 
treatment will be used. Otherwise, January 1 will be used. 
All imputation dates should be prior to the date of withdrew consent, lost to follow-up 
or death.  
10.4.10. Safety Analyses 
10.4.10.1. Analyses of Adverse Events 
Adverse events will be coded to MedDRA (v 18.1 or higher) for lower level term (LT), 
preferred term (PT) and primary system organ class (SOC). 
A treatment-emergent adverse event (TEAE) is defined as an adverse event (AE) that 
had an onset date after the start of the study treatment or that worsened in severity from 
baseline (pretreatment).  
Only those AEs that were treatment-emergent will be included in summary tables. All 
AEs, treatment-emergent or otherwise, will be presented in subject data listings. 
The incidence of TEAEs will be reported as the number (percentage) of subjects with 
TEAEs by SOC and preferred term. A subject will be counted only once by the highest 
severity grade per NCI-CTCAE v4.03 within an SOC and preferred term, even if the

10.4.10.2. Laboratory Tests Results 
Clinical laboratory (e.g., hematology, blood biochemistry) values will be evaluated as 
appropriate. Abnormal laboratory values will be flagged and identified as those outside 
(above or below) the normal range. The number and percentage of subjects 
experiencing Clinically significant laboratory values at baseline and worst post-dosing 
will be summarized by shift table. 
Laboratory parameters that are graded in NCI-CTCAE v4.03 will be summarized by 
NCI-CTCAE grade. In the summary of laboratory parameters by NCI-CTCAE grade, 
parameters with NCI-CTCAE grading in both high and low directions will be 
summarized separately.

The number and percentage of findings of clinically significant abnormal for vital signs 
will be summarized by experimental arm. A listing will also be provided for vital signs. 
The analyses of ECOG-PS will include summary statistics of baseline and highest score 
post baseline by experimental arm. 
The analyses of ECG will include summary statistics of baseline and worst clinically 
abnormal grade post baseline by experimental arm.  
10.4.11. Interim Analyses 
In this study, there is only one planned PFS analysis, which is planned at occur when 
~332 PFS events are observed (at ~19 months). OS analyses will be conducted at the 
following time points: at final PFS analysis, at 251 (70%) deaths if there are less than 
251 deaths at the final PFS analysis, and when ~359 OS events are observed (at ~36 
months.  
PFS 
If SHR-1210 in combination with rivoceranib arm demonstrated superiority over 
sorafenib (i.e., one-sided p-value < 0.005), its corresponding alpha level of 0.005 will 
be re-allocated to test the OS hypothesis at 0.025 one-sided with updated efficacy 
boundaries per Lan-DeMets O'Brien-Fleming spending function (see Table 15 ).  
OS 
A formal interim analysis (IA) for OS will be conducted after 70% (~251) of the target 
OS events are observed at ~23 months. The OBF was used for calculating efficacy 
boundaries (original 0.020/updated 0.025 alpha level). With ~251 OS events, the SHR-

132 
1210 in combination with rivoceranib mesylate will be considered superior than the 
sorafenib at the interim analysis, if the one-sided p-value for OS is less than 0.005/0.007, 
which corresponds to an observed HR of approximately 0.725/0.735. The trial will be 
considered positive at the final analysis, if the one-sided p-value for OS is less than 
0.018/0.023, which corresponds to an observed HR of approximately 0.802/0.810. If 
the null hypothesis for OS is rejected at either the interim (70%) or the final, its 
corresponding alpha level of 0.020 will be re-allocated to PFS so that the hypothesis 
for PFS maybe tested again at 0.025 one-sided. The boundary properties for the planned 
OS analyses based on the original and updated alpha levels can be found in Table 15
 
.  
In an anticipation that the number of OS events is < 251 OS events at the planned PFS 
analysis, a nominal alpha of 0.001% will be spent at the time of the planned PFS 
analysis. Since the trial will not stop early if there are less than 251 deaths, the 0.001% 
is considered for administrative purposes to avoid trial stop early. The study will 
continue to the next planned OS interim analysis (70%) and could continue to final 
analysis after ~251 OS events and ~359 OS events are observed, respectively, according 
to the efficacy boundaries as described in Table 15 . 
The analysis of PFS and the formal interim analysis (IA) of OS will be conducted by a 
Data Monitoring Committee (DMC) that recommends early discontinuation of the 
study for unequivocal efficacy at formal interim analysis (IA) of OS (~70% events), or 
continuation of the study for final analysis of OS. 
10.4.12. Multiplicity 
The two primary endpoints for the study are OS and PFS (assessed by BIRC based on 
RECIST v1.1). There is only one planned PFS analysis, which is expected to occur 
when approximately 332 PFS events are observed at approximately 19 months. OS 
analyses will be conducted at the following time points: at final PFS analysis, at 251 
(70%) deaths if there are less than 251 deaths at the final PFS analysis, and when ~359 
OS events are observed at ~36 months, respectively.  
The Type I error of 0.025 one-side is strongly controlled using the Weighted-Holm 
procedure with α-reallocation approach between PFS and OS endpoints as described in 
Ye et al 2013 [27] and O’Brien-Fleming alpha-spending function (OBF) within OS. The 
allocated α between two endpoints is α1=0.005 (one-sided) for PFS and α2=0.020 (one-
sided) for OS. If PFS endpoint is significant at α1=0.005, its α1 level will be re-allocated 
to endpoint OS so that the hypothesis for OS may be tested using its updated efficacy 
boundaries based on α level 0.025. Similarly, if endpoint OS is significant at α2=0.020 
according to the efficacy boundaries as determined by OBF, and PFS endpoint is not 
significant at α1=0.005, its α2 level will be re-allocated to PFS so that the hypothesis for 
PFS may be tested again at α level 0.025 (one-sided). The boundary properties for the 
planned OS analyses based on the original and updated alpha levels are summarized in 
Table 15 below:

(SHR-1210 + rivoceranib / Sorafenib) less than 1 indicates SHR-1210+rivoceranib 
group is superior than Sorafenib arm. The one-sided nominal significance level and 
stopping boundary will be determined by the actual percentage of events when the 
interim analysis is conducted. 
If both PFS and OS endpoints are not significant, then α-reallocation will not perform. 
If both the PFS and OS endpoints are significant, ORR assessed by BIRC according to 
RECIST v1.1 may be tested at 0.025 one-sided. The graphical approach in Figure 8 
shows the α-reallocation strategy for endpoints PFS and OS [28, 29]:

Above shows the initial one-sided α-allocation for each hypothesis in the ellipse 
representing the hypothesis. The weights for re-allocation from each hypothesis to 
another are represented in the rectangular boxes on the lines connecting hypotheses. 
When there are less than 251 OS events at the planned PFS analysis at ~19 months, a 
nominal α (0.001%, independent of OBF approach to allocate alpha) will be used, but 
the trial will not stop based on this OS result at the time of the PFS analysis. The study 
will continue to the next planned OS interim analysis (70%) and could continue to the 
final analysis after ~251 OS events and ~359 OS events at ~23 and ~36 months, 
respectively, at the alpha level as determined by the OBF boundaries and the actual 
number of OS events observed. The nominal alpha (0.001%) is considered, as this has 
negligible impact on overall Type I error rate and the study will not stop early for a 
positive OS result at the time of the PFS analysis.  
Any changes to the above strategy will be documented elsewhere, if not in a protocol 
amendment, at the earliest time before any formal analysis is being conducted. 
10.4.13. Subgroup Analyses 
To determine whether the treatment effect is consistent across various subgroups, HR 
and 95% CI for the primary endpoints OS and PFS (assessed by BIRC based on 
RECIST v1.1) will be estimated and plotted within each category of the following

Blinded Independent Review Committee 
A BIRC will be established to perform an independent review of all radiological images 
(imaging for tumor assessment will be provided by study centers to BIRC), and to 
determine all instances of response and disease progression on the basis of RECIST 
v1.1 and mRECIST criteria. If the investigator evaluates it as PD according to the 
RECIST v1.1 criteria, all radiological data must be submitted to BIRC, and PD will 
have to be confirmed by BIRC (Please refer to Figure 7 for PD confirmation process), 
and even if BIRC confirms PD per RECIST v1.1, the investigator needs to evaluate 
whether the subject continues to have benefit and meet the criteria for continued 
treatment beyond disease progression, and if so, the subject will continue the treatment 
and continue to be performed tumor radiological assessments. 
The tumor assessment by BIRC will be used for the reporting of the study results. All 
decisions made during the performance of the study will be on the basis of the local 
investigator’s assessment of radiographic images, clinical status, and relevant 
examination of the subjects. Sites will submit specific radiographic image files to the 
centralized data review facility during the study at an ongoing basis or at the sponsor’s 
request. Detail rules and guidelines for radiographic radiological and tumor assessments 
by BIRC will be outlined separately in the DMC charter, Image Acquisition Guidelines, 
and Central Laboratory Manual. 
10.6. Data Monitoring Committee 
The study will establish an independent Data Monitoring Committee (DMC) to 
regularly assess safety data, and analysis will be conducted for assessment of efficacy 
and safety at the time of PFS analysis and OS interim analysis. The DMC will provide 
advice on the measures that must be taken for protection of subjects and overall safety 
evaluation to the sponsor.  
The DMC is the consultant to the study team of the sponsor. The study team of the 
sponsor are responsible for overall conduction of the study, including management of

135 
the exchange and communication of study data, analysis based on the advice from the 
DMC, and making decisions on continuation of, amendment to or termination of the 
study.  
After the study is initiated, the DMC will hold meeting to evaluate safety data on a 
regular basis, as to ensure the subject’s safety is carefully supervised. The sponsor can 
also consult the DMC in a retrospective manner based on the safety signals discovered, 
and hold retrospective safety review meetings as required. The DMC can make 
recommendations for continuing, revising or terminating the study based on observed 
safety or efficacy data. Prior to the meeting, the DMC will look up and review the study 
data acquired, including the characteristics of the study population, dose information, 
safety and efficacy data in PFS analysis.  
The composition, responsibilities, frequency, format, operation and management of the 
DMC will be detailed in a separate DMC charter.

1.1 (RECIST v1.1) and Its Comparison with Immune-Modified 
RECIST (imRECIST) and Modified RECIST (mRECIST) 
RECIST v1.1 
1. Measurability of tumor at baseline 
1.1 Definitions 
At baseline, tumor lesions/lymph nodes will be categorized measurable or non-
measurable as follows: 
Measurable 
Tumor lesions: Must be accurately measured in at least one dimension (longest diameter 
in the plane of measurement is to be recorded) with a minimum size of: 
 
10 mm by CT scan (CT scan slice thickness no greater than 5 mm). 
 
10 mm caliper measurement by clinical exam (lesions which cannot be accurately 
measured with calipers should be 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 recommended to be no greater than 5 mm). At baseline and in 
follow-up, only the short axis will be measured and followed. 
Non-measurable 
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 radiological techniques. 
Special considerations regarding lesion measurability 
Bone lesions, cystic lesions, and lesions previously treated with local therapy require 
particular comment: 
Bone lesions: 
 
Bone scan, PET scan or plain films are not considered adequate radiological 
techniques to measure bone lesions. However, these techniques can be used to 
confirm the presence or disappearance of bone lesions.

Protocol Number: SHR-1210-III-310 
Version 6.0, 21 Sep 2022 
 
HENGRUI CONFIDENTIAL 
146 
 
Lytic bone lesions or mixed lytic-blastic lesions, with identifiable soft tissue 
components, that can be evaluated by cross sectional radiological techniques such 
as CT or MRI can be considered as measurable lesions if the soft tissue component 
meets the definition of measurability described above. 
 
Blastic bone lesions are non-measurable. 
Cystic lesions: 
 
Lesions that meet the criteria for radiographically defined simple cysts should not 
be considered as malignant lesions (neither measurable nor non-measurable) since 
they are, by definition, simple cysts. 
 
‘Cystic lesions’ thought to represent cystic metastases can be considered as 
measurable lesions, if they meet the definition of measurability described above. 
However, if non-cystic lesions are present in the same subject, these are preferred 
for selection as target lesions. 
Lesions with prior local treatment: 
 
Tumor lesions situated in a previously irradiated area, or in an area subjected to 
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. 
1.2 Specifications by methods of measurements 
Measurement of lesions 
All measurements should be recorded in metric notation, using calipers if clinically 
assessed. All baseline evaluations should be performed as close as possible to the 
treatment start and never more than 4 weeks before the beginning of the treatment. 
Method of assessment 
The same method of assessment and the same technique should be used to characterize 
each identified and reported lesion at baseline and during follow-up. Radiological based 
evaluation should always be done rather than clinical examination unless the lesion 
being followed cannot be imaged but are assessable by clinical exam. 
Clinical lesions: Clinical lesions will only be considered measurable when they are 
superficial and 10 mm diameter as assessed using calipers (e.g. skin nodules). For the 
case of skin lesions, documentation by color photography including a ruler to estimate 
the size of the lesion is suggested. As noted above, when lesions can be evaluated by 
both clinical exam and radiological, radiological evaluation should be undertaken since 
it is more objective and may also be reviewed at the end of the study. 
Chest X-ray: Chest CT is preferred over chest X-ray, particularly when progression is 
an important endpoint, since CT is more sensitive than X-ray, particularly in identifying 
new lesions. However, lesions on chest X-ray may be considered measurable if they are

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

Protocol Number: SHR-1210-III-310 
Version 6.0, 21 Sep 2022 
 
HENGRUI CONFIDENTIAL 
148 
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 includes the baseline sum if 
that is the smallest on study). In addition to the relative increase of 20%, the sum must 
also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or 
more new lesions is also considered progression). 
Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient 
increase to qualify for PD, taking as reference the smallest sum diameters while on 
study. 
2.2 Special notes on the assessment of target lesions 
Lymph nodes: Lymph nodes identified as target lesions should always have the actual 
short axis measurement recorded (measured in the same anatomical plane as the 
baseline examination), even if the nodes regress to below 10 mm on study. This means 
that when lymph nodes are included as target lesions, the ‘sum’ of lesions may not be 
zero even if CR criteria are met, since a normal lymph node is defined as having a short 
axis of <10 mm. Case report forms or other data collection methods may therefore be 
designed to have target nodal lesions recorded in a separate section where, in order to 
qualify for CR, each node must achieve a short axis <10 mm. For PR, SD and PD, the 
actual short axis measurement of the nodes is to be included in the sum of target lesions. 
Target lesions that 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 (e.g. 2 mm). However, sometimes 
lesions or lymph nodes which are recorded as target lesions at baseline become so faint 
on CT scan that the radiologist may not feel comfortable assigning an exact measure 
and may report them as being ‘too small to measure’. When this occurs it is important 
that a value be recorded on the case report form. If it is the opinion of the radiologist 
that the lesion has likely disappeared, the measurement should be recorded as 0 mm. If 
the lesion is believed to be present and is faintly seen but too small to measure, a default 
value of 5 mm should be assigned (Note: It is less likely that this rule will be used for 
lymph nodes since they usually have a definable size when normal and are frequently 
surrounded by fat such as in the retroperitoneum; however, if a lymph node is believed 
to be present and is faintly seen but too small to measure, a default value of 5 mm should 
be assigned in this circumstance as well). This default value is derived from the 5 mm 
CT slice thickness (but should not be changed with varying CT slice thickness). The 
measurement of these lesions is potentially non-reproducible, therefore providing this 
default value will prevent false responses or progressions based upon measurement 
error. To reiterate, however, if the radiologist is able to provide an actual measure, that 
should be recorded, even if it is below 5 mm.  
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’.

2.3 Evaluation of non-target lesions 
This section provides the definitions of the criteria used to determine the tumor response 
for the group of non-target lesions. While some non-target lesions may actually be 
measurable, they need not be measured and instead should be assessed only 
qualitatively at the time points specified in the protocol.  
Complete Response (CR): Disappearance of all non-target lesions and normalization of 
tumor marker level. All lymph nodes must be non-pathological in size (<10 mm short 
axis). 
Non-complete Response or non-PD: Persistence of one or more non-target lesion and/or 
maintenance of tumor marker level above the normal limits.  
Progressive Disease (PD): Unequivocal progression of existing non-target lesions. Note: 
the appearance of one or more new lesions is also considered progression. 
2.4 Special notes on assessment of progression of non-target disease  
The concept of progression of non-target disease requires additional explanation as 
follows. 
When the subject also has measurable disease: In this setting, 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 quality for unequivocal progression status. The 
designation of overall progression solely on the basis of change in non-target disease in 
the face of SD or PR of target disease will therefore be extremely rare.  
When the subject has only non-measurable disease: This circumstance arises in some 
phase 3 trials when it is not a criterion of study entry to have measurable disease. The 
same general concepts apply here as noted above, however, in this instance 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 (by definition: if all lesions are truly non-measurable) a useful test that can 
be applied when assessing subjects for unequivocal progression is to consider if the 
increase in overall disease burden based on the change in non-measurable disease is 
comparable in magnitude to the increase that would be required to declare PD for 
measurable disease: i.e. an increase in tumor burden representing an additional 73% 
increase in ‘volume’ (which is equivalent to a 20% increase diameter in a measurable 
lesion). Examples include an increase in a pleural effusion from ‘trace’ to ‘large’, an 
increase in lymphangitic disease from localized to widespread, or may be described in 
protocols as ‘sufficient to require a change in therapy’. If ‘unequivocal progression’ is 
seen, the subject should be considered to have had overall PD at that point. While it 
would be ideal to have objective criteria to apply to non-measurable disease, the very 
nature of that disease makes it impossible to do so, therefore the increase must be 
substantial. 
2.5 New lesions

Version 6.0, 21 Sep 2022 
 
HENGRUI CONFIDENTIAL 
150 
The appearance of new malignant lesions denotes disease progression; therefore, some 
comments on detection of new lesions are important. There are no specific criteria for 
the identification of new radiographic lesions; however, the finding of a new lesion 
should be unequivocal: i.e. not attributable to differences in scanning technique, change 
in radiological modality or findings thought to represent something other than tumor 
(for example, some ‘new’ bone lesions may be simply healing or flare of pre-existing 
lesions). This is particularly important when the subject’s baseline lesions show partial 
or complete response. For example, necrosis of a liver lesion may be reported on a CT 
scan report as a ‘new’ cystic lesion, which it is not.  
A lesion identified on a follow-up study in an anatomical location that was not scanned 
at baseline is considered a new lesion and will indicate disease progression. An example 
of this is the subject who has visceral disease at baseline and while on study has a CT 
or MRI brain ordered which reveals metastases. The subject’s brain metastases are 
considered to be evidence of PD even if he/she did not have brain radiological at 
baseline. 
If a new lesion is equivocal, for example because of its small size, continued therapy 
and follow-up evaluation will clarify if it represents 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. 
While FDG-PET response assessments need additional study, it is sometimes 
reasonable to incorporate the use of FDG-PET scanning to complement CT scanning in 
assessment of progression (particularly possible ‘new’ disease). New lesions on the 
basis of FDG-PET radiological can be identified according to the following algorithm: 
Negative FDG-PET at baseline, with a positivel FDG-PET at follow-up is a sign of PD 
based on a new lesion. 
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. 
2.6 Missing assessments and not evaluable designation 
When no radiological/measurement is done at all at a particular time point, the subject 
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 would not change the assigned time point response.

151 
2.7 Special notes on response assessment 
When nodal disease is included in the sum of target lesions and the nodes decrease to 
‘normal’ size (<10 mm), they may still have a measurement reported on scans. This 
measurement should be recorded even though the nodes are normal in order not to 
overstate progression should it be based on increase in size of the nodes. As noted earlier, 
this means that subjects with CR may not have a total sum of ‘zero’ on the case report 
form (CRF). 
In trials where confirmation of response is required, repeated ‘NE’ time point 
assessments may complicate best response determination. The analysis plan for the trial 
must address how missing data/assessments will be addressed in determination of 
response and progression. For example, in most trials it is reasonable to consider a 
subject with time point responses of PR-NE-PR as a confirmed response. 
Subjects with a global deterioration of health status requiring discontinuation of 
treatment without objective evidence of disease progression at that time should be 
reported as ‘symptomatic deterioration’. Every effort should be made to document 
objective progression even after discontinuation of treatment. Symptomatic 
deterioration is not a descriptor of an objective response: it is a reason for stopping 
study therapy. The objective response status of such subjects is to be determined by 
evaluation of target and non-target disease as shown in Tables 1-3 below. 
Conditions that define ‘early progression, early death and inevaluability’ are study 
specific and should be clearly described in each protocol (depending on treatment 
duration, treatment periodicity). 
In some circumstances it may be difficult to distinguish residual disease from normal 
tissue. When the evaluation of complete response depends upon this determination, it 
is recommended that the residual lesion be investigated (fine needle aspirate/biopsy) 
before assigning a status of complete response. FDG-PET may be used to upgrade a 
response to a CR in a manner similar to a biopsy in cases where a residual radiographic 
abnormality is thought to represent fibrosis or scarring. The use of FDG-PET in this 
circumstance should be prospectively described in the protocol and supported by 
disease specific medical literature for the indication. However, it must be acknowledged 
that both approaches may lead to false positive CR due to limitations of FDG-PET and 
biopsy resolution/sensitivity.

‘Non-CR/non-PD’ is preferred over ‘stable disease’ for non-target disease since SD is increasingly used 
as endpoint for assessment of efficacy in some trials so to assign this category when no lesions can be 
measured is not advised. 
For equivocal findings of progression (e.g. very small and uncertain new lesions; cystic 
changes or necrosis in existing lesions), treatment may continue until the next scheduled 
assessment. If at the next scheduled assessment, progression is confirmed, the date of 
progression should be the earlier date when progression was suspected.

meeting PR criteria relative to baseline, makes the disease PD at that point (since disease must have 
reappeared after CR). Best response would depend on whether minimum duration for SD was met. 
However, sometimes ‘CR’ may be claimed when subsequent scans suggest small lesions were likely still 
present and in fact the subject had PR, not CR at the first time point. Under these circumstances, the 
original CR should be changed to PR and the best response is PR. 
2.8 Confirmatory measurement/duration of response 
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. In randomized trials (phase 2 or 3) 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. 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. 
Duration of overall response 
The duration of overall response is measured from the time measurement criteria are 
first met for CR/PR (whichever is first recorded) until the first date that recurrent or PD 
is objectively documented (taking as reference for PD the smallest measurements 
recorded on study). The duration of overall CR is measured from the time measurement 
criteria are first met for CR until the first date that recurrent disease is objectively 
documented. 
Duration of stable disease 
Stable disease is measured from the start of the treatment (in randomized trials, from 
date of randomization) until the criteria for progression are met, taking as reference the 
smallest sum on study (if the baseline sum is the smallest, this is the reference for 
calculation of PD). The clinical relevance of the duration of stable disease varies in 
different studies and diseases. If the proportion of subjects achieving stable disease for 
a minimum period of time is an endpoint of importance in a particular trial, the protocol 
should specify the minimal time interval required between two measurements for 
determination of stable disease. 
Note: The DoR and stable disease as well as the PFS are influenced by the frequency 
of follow-up after baseline evaluation. It is not in the scope of this guideline to define a 
standard follow-up frequency. The frequency should take into account many parameters 
including disease types and stages, treatment periodicity and standard practice. 
However, these limitations of the precision of the measured endpoint should be taken 
into account if comparisons between trials are to be made. 
2.9 Progression-free survival/proportion progression-free 
Phase 3 trials in advanced cancers are increasingly designed to evaluate PFS or TTP as 
the primary outcome of interest. Assessment of progression is relatively straightforward 
if the protocol requires all subjects to have measurable disease. Increasingly, trials allow 
entry of both subjects with measurable disease as well as those with non-measurable 
disease only. In this circumstance, care must be taken to explicitly describe the findings 
which would qualify for PD for those subjects without measurable lesions. Because the

Briefly, immune-modified Response Evaluation Criteria in Solid Tumors (imRECIST) 
allows for collection of additional scans and for BOR to occur after radiologic PD 
assessment(s) in subjects continuing treatment (see Table 4 below). New lesions are 
added to the total tumor burden along with the sum of the target lesions when 
measurable; when not measurable, they are not factored into the PD assessment. In 
addition, progression in non-target lesions does not define PD. For analysis of 
imRECIST-defined PFS (imPFS), imRECIST PD or death is considered an event; 
however, an imRECIST PD is not considered an imPFS event if the time point response 
at the subsequent scan (≥ 4 weeks later) is imRECIST SD/PR/CR. An imRECIST PD 
followed by no additional assessments is considered an imPFS event.

Target Lesions 
When more than one measurable lesion is present at baseline, all lesions up to a 
maximum of 5 lesions total (and a maximum of 2 lesions per organ) representative of 
all involved organs should be identified as target lesions and will be recorded and 
measured at baseline. 
Non-Target Lesions 
After baseline, changes in non-target lesions will contribute only in the assessment of 
CR (i.e., a CR is attained only with the complete disappearance of all tumor lesions, 
including non-target lesions) and will not be used to assess PD. 
New Lesions 
During the study, all new lesions identified and recorded after baseline must be assessed 
at all tumor assessment timepoints. New lesions will also be evaluated for measurability 
with use of the same criteria applied to prospective target lesions at baseline per 
RECIST, (e.g., non−lymph node lesions must be ≥ 10 mm; see note for new lymph node 
lesions below). Up to a maximum of 5 new lesions total (and a maximum of 2 lesions 
per organ), all with measurements at all timepoints, can be included in the tumor 
response evaluation. New lesion types that would not qualify as target lesions per 
RECIST cannot be included in the tumor response evaluation but can be used for CR 
exclusion. 
New lesions that are not measurable at first appearance but meet measurability criteria 
at a subsequent timepoint will be measured from that point on and contribute to the sum 
of longest diameters (SLD), if the maximum number of 5 measurable new lesions being 
followed has not been reached.

Calculation of Sum of the Diameters 
A sum of the diameters (longest for non-nodal lesions, short axis for nodal lesions) for 
all target lesions will be calculated as a measure of tumor burden. 
The sum of the diameters is calculated at baseline and at each tumor assessment for the 
purpose of classification of tumor responses. 
Sum of the Diameters at Baseline: The sum of the diameters for all target lesions 
identified at baseline prior to treatment on Day 1. 
Sum of the Diameters at Tumor Assessment: For every on-study tumor assessment 
collected per protocol or as clinically indicated the sum of the diameters at tumor 
assessment will be calculated using tumor radiological scans. All target lesions selected 
at baseline and up to 5 new measurable lesions (with a maximum of 2 new lesions per 
organ) that have emerged after baseline will contribute to the sum of the diameters at 
tumor assessment. Hence, each net percentage change in tumor burden per assessment 
with use of modified RECIST accounts for the size and growth kinetics of both old and 
new lesions as they appear. 
Note: In the case of new lymph nodes, RECIST v1.1 criteria for measurability 
(equivalent to baseline target lesion selection) will be followed. That is, if at first 
appearance the short axis of a new lymph node lesion ≥ 15 mm, it will be considered a 
measurable new lesion and will be tracked and included in the SLD. Thereafter, the 
lymph node lesion will be measured at subsequent timepoints and measurements will 
be included in the SLD, even if the short axis diameter decreases to <15 mm (or even 
<10 mm). However, if it subsequently decreases to < 10 mm, and all other lesions are 
no longer detectable (or have also decreased to a short axis diameter of < 10 mm if 
lymph nodes), then a response assessment of CR may be assigned. 
If at first appearance the short axis of a new lymph node is ≥ 10 mm and < 15 mm, the 
lymph node will not be considered measurable but will still be considered a new lesion. 
It will not be included in the SLD unless it subsequently becomes measurable (short 
axis diameter ≥ 15 mm). 
The appearance of new lymph nodes with diameter < 10 mm should not be considered 
pathological and not considered a new lesion. 
Response Criteria 
Timepoint Response 
It is assumed that at each protocol-specified timepoint, a response assessment occurs. 
Table 6 provides a summary of the overall response status calculation at each timepoint 
for subjects who have measurable disease at baseline. 
Complete Response (CR): Disappearance of all target and non-target lesions. Lymph 
nodes that shrink to <10 mm short axis are considered normal. 

Study Drug Number: SHR-1210 
Protocol Number: SHR-1210-III-310 
Version 6.0, 21 Sep 2022 
 
HENGRUI CONFIDENTIAL 
158 
Partial Response (PR): At least a 30% decrease in the sum of the diameters of all 
target and all new measurable lesions, taking as reference the baseline sum of diameters, 
in the absence of CR. 
Note: the appearance of new measurable lesions is factored into the overall tumor 
burden but does not automatically qualify as PD until the sum of the diameters increases 
by ≥ 20% when compared with the sum of the diameters at nadir. 
Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient 
increase to qualify for PD, taking as reference the smallest sum of the diameters while 
on study. 
Progressive Disease (PD): At least a 20% increase in the sum of diameters of all target 
and selected new measurable lesions, taking as reference the smallest sum on study 
(nadir SLD; this includes the baseline sum if that is the smallest on study). In addition 
to the relative increase of 20%, the sum must also demonstrate an absolute increase of 
at least 5 mm. 
Impact of New Lesions on imRECIST 
New lesions alone do not qualify as progressive disease. However, their contribution to 
total tumor burden is included in the sum of the diameters, which is used to determine 
the overall modified RECIST tumor response. 
Missing Assessments and Not Evaluable Designation 
When no radiological/measurement is done at all at a particular timepoint, the subject 
is considered not evaluable (NE) at that timepoint. If only a subset of lesion 
measurements is made at an assessment, usually the case is also considered NE at that 
timepoint, unless a convincing argument can be made that the contribution of the 
individual missing lesion(s) would not change the assigned timepoint response. This 
would only happen in the case of PD. For example, if a subject had a baseline sum of 
50 mm with 3 measured lesions and at follow-up only 2 lesions were assessed but those 
gave a sum of 80 mm, the subject will be assigned PD status, regardless of the 
contribution of the missing lesion.

APPENDIX 6.  Recommended Treatment Procedures for 
Common Immune-Related Adverse Events 
When dealing with immune-related AEs, the investigator may refer to the following 
treatment procedures for common immune-related AEs. These procedures are 
recommended based on Management of Toxicities From Immunotherapy: ESMO 
Clinical Practice Guidelines for Diagnosis, Treatment and Follow-Up (Annals of 
Oncology 28 (supplement 4):iv119-iv142, 2017)” in combination with this study 
protocol. 
The general principle is that AEs should go through careful assessment and differential 
diagnosis in accordance with medical standards; non-inflammatory causes should be 
considered and properly managed. 
Corticosteroids are the main therapeutic agents for Immuno-Oncology (I-O) drug 
related AEs. Subjects with low-grade toxicities who can walk around may consider oral 
doses equivalent to recommended intravenous doses. If the equivalent dose of oral 
corticosteroids is changed, the lower bioavailability of oral corticosteroids should be 
considered. 
It is recommended to consult with physicians or surgeons, especially prior to invasive 
diagnosis or treatment.

Renal injury occurs in around 1%-4% of subjects treated with ICPi, usually a pattern of acute

baseline creatinine, not just abnormal results per biochemistry upper limit of normal (ULN). 
Confounding diagnoses include dehydration, recent i.v. contrast, urinary tract infection, 
medications, hypotension, or hypertension. Early consideration for renal biopsy is helpful which 
may negate the need for steroids and determine whether renal deterioration is related to ICPi or 
other pathology. Oliguria should prompt insubject admission for careful fluid balance and plan for 
renal replacement therapy. Steroid wean: begin to wean once creatinine Grade 1; Grade 2 severity

emollients, antihistamines in the case of pruritus and/or topical (mild strength) 
corticosteroid creams. Reinitiate ICPi when ≤ Grade 1. 
• 
For Grade 3 skin AEs, interrupt ICPi and start immediate treatment with topical 
emollients, antihistamines and high strength corticosteroid creams. [II, B] 
• 
For Grade 4 skin AEs, discontinue ICPi (permanently), consider admitting subject 
and always consult dermatologist immediately. Start i.v. corticosteroids [1–2 mg/kg 
(methyl) prednisone] and taper based on response of AE. [II, B] 
• 
Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare 
but life-threathening severe cutaneous adverse reaction. Patients with SJS/TEN 
usually develop mucosal erosions or ulcers with variable extents of skin 
detachment after immunotherapy for a period of 1-3 weeks, it also may occur 
several months after treatment initiation. SJS and TEN are thought be a spectrum 
of the same disease. SJS, overlapping SJS/TEN, and TEN are characterized by 
separation of the dermis involving <10%, 10%-30%, and >30% body surface area 
(BSA). The management of Stevens-Johnson syndrome (SJS)/toxic epidermal 
necrolysis (TEN) is detailed in below Table 16. 
Table 16 
SJS/TEN management and treatment 
Early identification and management 
·Inform patients of the symptoms and signs of SJS/TEN; advise patients to promptly 
notify investigator if signs of SJS/TEN occur 
·Consider withhold study drugs (SHR-1210 and rivoceranib) and monitor patients 
closely every 3 days with Grade 2 immune-related rash for progression to 
involvement of greater BSA and/or mucous membrane involvement. Initiate 
therapy with topical corticosteroids. Consider initiation of prednisone (or 
equivalent) 0.5-1 mg/kg tapered over at least 4 weeks 
·In cases of suspected SJS, withhold study drugs and consider early admission for 
further monitoring and treatment. 
Initial assessment on presentation 
·Review patient history, and a full list of patient medications 
·Total body skin examination with attention to ALL mucous membranes as well as a 
complete review of systems 
·Rule out any other etiology of the skin problem, such as an infection, another drug, 
or a skin condition linked to another systemic disease 
·Perform skin biopsies for full-thickness epidermal necrosis to confirm the diagnosis

of SJS/TEN. 
Treatment for SJS/TEN 
·Should permanently discontinue SHR-1210 and rivoceranib once SJS/TEN is 
confirmed 
·Should admit patient immediately with urgent consultation with dermatologist 
·Initiate IV (methyl) prednisolone (or equivalent) 1-2 mg/kg, wean over at least 4 
weeks when toxicity resolves to Grade ≤1. May consider intravenous 
immunoglobulin (IVIG) or cyclosporine as an alternative or in corticosteroid-
refractory cases 
·For mucous membrane involvement of SJS or TEN, seek urgent dermatology, 
ophthalmology, and urology consultation to prevent sequelae from scarring 
·Supportive care should include assessment and management of skin wounds, fluid 
and nutrition status, electrolyte balance, renal and airway function, preventing 
infection, and adequate pain control 
·Seek infectious disease consultation if patient might have secondary cellulitis or if 
patient has other infection risk factors, such as neutropenia, etc. 
 
Immune-related endocrinopathies 
• For subjects with Grade 2 symptomatic hyperthyroism, interrupt ICPi, start beta-
blocker therapy (propranolol or atenolol/metoprolol). Restart ICPi when 
asymptomatic [IV–V, B]. 
• In the case of hypothyroidism, rarely>Grade 2, start HRT depending on the severity 
(50–100 lg/day). Increase the dose until TSH is normal. In the case of inflammation 
of the thyroid gland, start prednisone orally 1 mg/kg. Taper based on recovery of 
clinical symptoms. Consider interruption of ICPi treatment when symptomatic [IV–
V, B]. 
• In the case of hypophysitis (rarely>Grade 2), when headache, diplopia or other 
neurological symptoms are present, start (methyl) prednisone 1 mg/kg orally and 
taper over 2–4 weeks. Start HRT depending on the affected hormonal axis 
(levothyroxine, hydrocortisol, testosterone) [V, B]. 
• In subjects with type I DM Grade 3 to 4 [ketoacidotic (sub)coma], admit to hospital 
immediately and start treatment of newly onset type I DM [I, A]. Role of 
corticosteroids in preventing complete loss of insulin producing cells is unknown 
and not recommended. 
Gastrointestinal hepatotoxicity 
• 
In subjects with non-severe diarrhoea (Grade 1), ICPi can be continued. Treatment 
with antidiarrhoeal medication (e.g. loperamide) should be prescribed [IV–V, B].

Version 6.0, 21 Sep 2022 
 
HENGRUI CONFIDENTIAL 
174 
• 
In Grade 2 diarrhoea, ICPi should be interrupted and the subject should start with 
corticosteroids depending on the severity and other symptoms (either budesonide 
or oral corticosteroids 1 mg/kg). In the case of no improvement within 3–5 days, 
colonoscopy should be carried out and, in the case of colitis, infliximab 5 mg/kg 
should be administered [IV–V, B]. 
• 
In subjects with severe diarrhoea (Grade 3 to 4), permanently discontinue ICPi. 
Admit subject to the hospital and initiate (methyl) prednisone 2 mg/kg i.v. Add 
MMF if improvement is observed within 2–3 days. Consult a hepatologist if no 
improvement under double immunosuppression. Other immunosuppressive drugs 
to consider are ATG and tacrolimus. Consult or refer subject to an experienced 
center. Taper over 6 weeks under close monitoring of liver tests [IV–V, B]. 
Immune-related pneumonitis 
• 
For subjects with Grade 2 pneumonitis, interrupt ICPi therapy, try to rule out 
infection and start with prednisone 1–2 mg/kg orally. Taper over 4–6 weeks [IV–V, 
B]. 
• 
In Grade 3 and 4 pneumonitis, discontinue ICPi permanently, admit the subject to 
the hospital, even ICU if necessary and immediately start high-dose (methyl) 
prednisone 2–4 mg/kg i.v. Add infliximab, MMF or cyclophosphamide in the case 
of deterioration under steroids. Taper over a period of 4–6 weeks [IV–V, B]. 
Cardiac toxicity 
• 
When a myocarditis is suspected, admit the subject and immediately start high-
dose (methyl) prednisone (1–2 mg/kg). In the case of deterioration, consider adding 
another immunosuppressive drug (MMF or tacrolimus) [V, B]. 
Rheumatological toxicity 
• 
For mild arthralgia, start NSAIDs, and in the case of no improvement, consider 
low -dose steroids (10–20 mg prednisone). In the case of severe polyarthritis, refer 
subject to or consult a rheumatologist and start prednisone 1 mg/kg. Sometimes 
infliximab or another anti-TNFa drug is required for improvement of arthritis [V, 
B]. 
Renal toxicity 
• 
In case of nephritis, rule out other causes of renal failure first. Interrupt or 
permanently discontinue ICPi depending on the severity of the renal insufficiency. 
Stop other nephrotoxic drugs. Start (methyl) prednisone 1–2 mg/kg. Consider renal 
biopsy to confirm diagnosis [V, B].

APPENDIX 7. Grade and Management of Reactive Capillary 
Endothelial Proliferation (RCEP) 
RCEP mostly occurs on the surface of the skin, a small number can be found in the oral 
mucosa, nasal mucosa and orbital conjunctiva. RCEP occurring in the skin, initially 
expressed as a bright red spot on the body surface, diameter ≤ 2 mm, with the increase 
of medication times, the lesion range can be gradually increased, mostly nodular, also 
patchy, the color is bright red or dark red, need to observe the clinical symptoms and 
signs. It can be treated according to the following grading standards and treatment 
recommendations: 
Grade 
Clinical Manifestation 
Treatment Suggestions 
Grade 1 
Single or multiple, nodule with 
longest diameter ≤10 mm, 
with or without rupture 
bleeding 
Continue administration, enhance 
local treatment for those with rupture 
and bleeding to prevent infection 
Grade 2 
Single or multiple, nodule with 
longest diameter >10mm, 
with or without rupture 
bleeding 
Continue the study treatment. 
Conduct local therapy such as laser or 
surgical resection if needed. 
Strengthen local treatment and prevent 
infection for subjects with rupture 
bleeding. 
Grade 3 
Widespread nodules, 
complicated by skin infections, 
maybe need hospitalization  
Interrupt the study treatment until 
resolution of the AE to Grade 1. 
Conduct local therapy such as laser or 
surgical resection if needed. 
Conduct anti-infection treatment for 
subjects with concurrent infection. 
Grade 4‡ 
Multiple and widespread 
nodule, life threatening 
Discontinue the study treatment 
Grade 5‡ 
Death 
Discontinue the study treatment 
† Grading is based on <Management of Immune Checkpoint Inhibitor-Related Toxicity-Guidelines 
of Chinese Society of Clinical Oncology (CSCO) 2019>. 
‡Grade 4 life threatening and Grade 5 death have not occured in the study.  
Avoid scratch or friction when adverse reaction occurs. Protect easily rubbing parts by 
gauze to avoid bleeding and contact the doctor in charge for appropriate treatment 
suggestions. Hemostasis by local compression or local treatment such as laser or 
surgical excision can be used in subjects with ruptured hemorrhage. Anti-infective 
treatment should be given to those complicated with infection. RCEP may occur in 
tissues other than skin (including visceral organs). Related medical examinations such 
as fecal occult blood, endoscopy and radiological should be performed if necessary.
