Drug 
SHR-1210 Injection 
Method of 
Administration 
All subjects will receive an intravenous infusion of SHR-1210 at 200 mg/dose 
over 30 min (not less than 20 min and not more than 60 min, including 
rinsing), once every two weeks (q2w), until the following conditions occur: 
progressive disease, intolerable toxicity, or other reasons specified in the 
protocol. 
Inclusion 
Criteria 
Patients must meet all of the following criteria to be eligible for this study: 
1. 
Age ≥ 18 years old, male or female; 
2. 
With histologically identified cHL; 
3. 
Have relapsed (confirmed progressive disease [PD] after the latest 
treatment) or refractory (failure to achieve complete response or partial 
response after the latest treatment) cHL, and must meet any of the 
following criteria: 
a) 
Have not reached response after autologous hematopoietic stem 
cell transplant or have progressed;

2) ANC ≥ 1.0 × 109/L; 
3) PLT ≥ 75 × 109/L; 
Clinical chemistry: 
1) TBIL < 1.5 × upper limit of normal (ULN); 
2) ALT and AST ≤ 2.5 × ULN; 
3) Serum Cr ≤ 1.25 × ULN or endogenous CrCl ≥ 45 mL/min 
(Cockcroft-Gault formula) 
Coagulation function (unless the subject is receiving anticoagulant 
therapy and the coagulation parameters (PT/INR and APTT) at the time 
of screening are within the expected range of anticoagulant therapy): 
1) International normalized ratio (INR) ≤ 1.5 × ULN; 
2) Activated partial thromboplastin time (APTT) ≤ 1.5 × ULN;

sample collection 
PK Study 
A PK study will be carried out in 12 subjects enrolled in this study (the PK 
study will only be carried out in Beijing Cancer Hospital, the leading site). 
1) There are 4 blood collection time points for the single dose in Cycle 1: 
within 0.5 h pre-administration on D1, within 5 min and at 2 h (± 10 min)  
after the end of administration on D1, and on D8 (± 60 min).  
2) In Cycles 2, 4, and 6, a total of 2 blood sampling time points: within 0.5 h 
pre-administration and 5 min post-administration on D1. 
The concentration of the parent drug in the blood sample will be 
determined, and the primary multiple-dose PK parameters will be 
investigated, mainly including: 
1) Cmax: maximum blood concentration; 
2) Cmin: minimum blood concentration; 
3) Tmax: time to the maximum concentration; 
4) Elimination half-life (t1/2z); 
5) Area under the concentration-time curve (AUC); 
6) Apparent volume of distribution (Vz); 
7) Systemic clearance (CLS); 
The above PK parameters of SHR-1210 in the human body will be calculated 
using the non-compartmental model. For multiple-dose pharmacokinetics, 
drug accumulation will be studied according to the maximum concentration 
and minimum concentration in multiple cycles.

Determination 
of Sample Size 
This study uses a single-arm design. The primary objective is to evaluate the 
efficacy of SHR-1210 in the treatment of relapsed or refractory cHL. The 
study endpoint is ORR. By referring to historical research data and research 
results of similar products and given the current clinical practice 
requirements, the investigational drug can be judged as effective only when 
the lower limit of the 95% confidence interval for ORR obtained from the 

Compound Name: SHR-1210 
Protocol No.: SHR-1210-II-204 
Version 3.0, Version Date: 19 Jul., 2017 
 
 
Hengrui Confidential 
19 
study data is greater than 40%. Therefore, the sample size for this study is 
determined based on the following 2 points: 1. the exact method (Clopper-
Pearson) is used to calculate the 95% confidence interval for ORR; 2. the 
lower limit of the confidence interval is greater than 40%. Assuming that the 
ORR of SHR-1210 in the treatment of relapsed or refractory cHL reaches 
65%, a power of 92.90% can be obtained with 50 subjects. Given a dropout 
rate of 20%, this study intends to enroll 60 subjects. 
Data Analysis/ 
Statistical 
Methods 
Analysis sets/populations 
This study will involve the following analysis sets or populations: 
 
Informed Consent Set (ICS):  
all subjects who have signed the informed consent form. 
 
Full Analysis Set (FAS):  
eligible subjects who have received the investigational drug. The 
FAS is the primary analysis set for efficacy analysis other than the 
primary efficacy endpoint. 
 
Evaluable Set (ES): 
a subset of the FAS, defined as subjects with at least one post-
baseline efficacy evaluation in the FAS. The ES is the primary 
analysis set for the primary efficacy endpoint ORR. 
 Per-Protocol Set (PPS):  
a subset of the FAS, defined as subjects in the FAS who have 
experienced no major protocol deviations. PPS is the secondary 
analysis set for efficacy analysis. Safety Set (SS): all enrolled 
subjects who have received the investigational drug and have post-
administration evaluable safety data. SS is the primary analysis set 
for safety analysis. 
 PK Set (PKS):  
all enrolled subjects who have received the investigational drug and 
have post-administration evaluable PK data (concentration and/or 
parameters). 
General analysis 
Unless otherwise specified, all data in this study will be summarized using 
descriptive statistics according to the data type. Measurement data will be 
summarized using mean, standard deviation (SD), median, minimum, and 
maximum; count data and rank data will be summarized using frequency and

20 
percentage; for time to event data, the Kaplan-Meier method will be used to 
estimate the median time and its overall 95% confidence interval will be 
calculated. 
Efficacy analysis 
For the objective response rate (ORR) based on the IRC's and investigators' 
assessment, point estimation will be performed, and the exact method 
(Clopper-Pearson) will be used to estimate the overall 95% confidence 
interval. 
For other secondary efficacy endpoints, including duration of response 
(DoR), progression-free survival (PFS), time to response (TTR), and overall 
survival (OS), the Kaplan-Meier method will be used to estimate their 
median times and the overall 95% confidence intervals will be calculated. 
The analysis of the primary efficacy endpoint will be based on the ES, and 
other efficacy analyses will be repeated based on the primary analysis set 
FAS and secondary analysis set PPS. 
Safety analysis 
The safety analysis will be summarized primarily using descriptive statistics. 
AEs, treatment-emergent AEs (TEAEs), SAEs, laboratory data, vital signs, 
and other data will be statistically summarized. Also, the exposure to the 
investigational drug (including treatment cycle, received total dose, and dose 
intensity) will be statistically summarized. The above data will be analyzed 
and summarized using Hengrui's current clinical study report standards. Such 
standards include but are not limited to the following: 
Summary of AEs (of all causes and treatment-related); 
Incidence and severity of AEs (of all causes and treatment-related); 
Correlation analysis between AEs and investigational drug; 
Analysis of outcomes of AEs; 
Analysis of SAEs; 
Descriptive statistical summary of laboratory measurements, vital sign data, 
and ECG data (post-baseline absolute values and post-baseline changes from 
baseline); 
Classified summary of post-baseline vital sign data and ECG.

Statistical analysis of PK 
PK analyses will be based on the PKS, and PK concentration and PK 
parameters will be summarized using descriptive statistics. Apart from the 
statistics listed in the general analysis, PK concentration and PK parameter 
data will be also summarized descriptively using geometric mean (GM), 
coefficient of variation (CV%), and geometric CV% (GCV%). In addition, 
for PK concentration data, average and median blood concentration-time 
curves (concentration-time curves) on linear scale and semi-logarithmic scale 
can be plotted, and individual subjects' concentration-time curves (linear 
scale and semi-logarithmic scale) can be plotted at the same time. If PK 
statistical analysis is outsourced, the statistical analysis plan provided 
independently by the vendor shall prevail for the specific statistical analysis 
and method plan.

Note: In addition to the examinations and time points shown in this table, the investigators may order additional tests at any time. Test results should be entered 
into the "Unscheduled Tests" sheet of the eCRF. 
[1] 
Screening period: physical examination, vital signs, laboratory tests (including hematology, urinalysis, fecal occult blood, Hepatic and Renal Function, 
LDH, erythrocyte sedimentation rate, blood electrolytes, fasting blood glucose, coagulation function, thyroxine, virological examination, etc.), ECG, 
echocardiography (including LVEF) are tested within 14 days before the start of the study treatment; tumor CT or MRI examination (chest, abdomen, 
pelvis, and other sites of known lesions), FDG-PET examination, and bone marrow aspiration and biopsy are performed within 28 days before the start of 
the study treatment; blood HCG test is performed within 7 days before the start of the study treatment. 
[2] 
Treatment cycle: In the event of a dose delay, the scheduled visit items at the same time point should be delayed accordingly to ensure consistency with 
the actual time of administration. Imaging evaluation (including CT or MRI examination, FDG-PET examination) should be carried out according to the 
scheduled time point and is not related to administration. 
[3] 
End of study treatment/withdrawal from study: Examinations are not required at this stage if tumor CT or MRI has been performed within 4 weeks and 
safety evaluation and B symptom assessment have been completed within 7 days prior to treatment discontinuation. 
[4] 
Physical examination: including height, weight, symptoms, and signs. Lymph node regions (for example, submandibular, cervical, supraclavicular, armpit, 
and groin) and abdominal organs (for example, liver and spleen) are checked within 72 h before each administration. 
[5] 
Vital signs: including body temperature, blood pressure, heart rate, and respiratory rate; measure within 72 h before each administration.

[6] 
Safety follow-up: until 90 days after the last dose. The first visit should be conducted 30 days (± 7 d ays) after the last dose or on the day of treatment 
discontinuation (if the date of treatment discontinuation is more than 84 days after the date of the last dose). The second visit is conducted approximately 
90 days (± 7 days) after the last dose. Both vi sits must be conducted at study sites. 
[7] 
Urinalysis: In case of a urine protein ≥ 2+ at screening, a 24-h urine protein quantitation should be added.  
[8] 
Hepatic and Renal Function: including ALT, AST, TBIL, ALP, BUN or serum urea level, creatinine, and albumin; blood electrolytes: including K+, Na+, 
Ca++, Mg++, and Cl-. 
[9] 
Coagulation function: When international normalized ratio (INR) is not available, prothrombin time (PT) will be used. Measure once every 2 cycles 
during treatment 
[10] 
Thyroid function: including TSH, FT3, and FT4. Measure once every 4 cycles during treatment 
[11] 
Virological examination: including HIV-Ab, HBV, and HCV infection testing. HBV testing requirements: HbsAg (qualitative), HbsAb (qualitative), 
HbcAb (qualitative), HbeAg (qualitative), and HbeAb (qualitative) should be tested at screening. If HBV infection is suspected, HBV-DNA should be 
tested (qualitatively; if positive, then quantitatively). HCV testing requirements: HCV-Ab is tested at screening to determine the presence of HCV 
infection. If positive, HCV-RNA will be tested (qualitatively; if positive, then quantitatively). For patients with hepatitis virus infection during the 
screening period, virological examination will be performed every 2 cycles during the treatment period, and the examination will be performed at the end 
of the treatment and during the safety follow-up; for patients with HBV infection, they will be tested for HBV-DNA (quantitative), and for patients with 
HCV infection, they will be tested for HCV-RNA (quantitative). 
[12] 
Blood HCG test: Only for women of child bearing potential (WOCBP); test within 7 days before the first dose, and at least once every 4 weeks (± 7 days) 
thereafter, regardless of the dosing cycle. 
[13] 
Echocardiography: Perform according to local standard practice when clinically indicated. 
[14] 
Tumor CT or MRI examination: Evaluate according to IWG2014 criteria, including CT scans with contrast of the chest, abdomen, pelvis, and any other 
sites of known lesions (such as neck). If the subject is allergic to contrast media or has bronchial asthma, kidney damage, or other diseases that make it 
difficult to perform contrast imaging, the subject can undergo chest CT without contrast + MRI scans of abdomen, pelvis, and any other sites of known 
lesions (such as neck). Evaluation will be carried out on D1 (± 7 days) of Weeks 9, 17, 25, 37, and 49 after the start of treatment, then every 16 weeks 
(± 14 days) until Week 97, and then every 26 weeks (± 21 days) until PD (for subjects who continue to receive the study treatment a fter radiographic 
progression, evaluation will be carried out until the investigational drug is discontinued), start of new anti-tumor treatment, or death. 
[15] 
Tumor FDG-PET examination: Perform on D1 (± 7 days) of Weeks 17 and 25 after the start of treatment. For subjects who have not obtained two 
negative FDG-PET results after Week 1 and until Week 49, it is necessary to add a tumor FDG-PET examination on D1 (± 7 days) of Week 49. If it is 
necessary to determine whether a radiographic CR is obtained at other unscheduled FDG-PET evaluation time points after the start of treatment, the FDG-
PET evaluation must be performed within 4 weeks after the CT evaluation.

[16] 
Bone marrow aspiration and biopsy: The subject can start the study treatment before obtaining the bone marrow biopsy result, but the result must be 
recorded in the subject's CRF. Patients with bone marrow involvement at baseline require bone marrow aspiration or biopsy to confirm CR status. Bone 
marrow aspiration and biopsy specimens are collected within 2 weeks after the CT scan. There is no need to perform bone marrow assessment after the 
bone marrow aspiration and biopsy result turns negative. 
[17] 
B symptom assessment: including pyrexia of > 38 °C of unknown cause; night sweats; weight loss of > 10% within 6 mont hs before the assessment. The 
evaluation will be conducted on D1 of Cycle 1, and every 2 cycles thereafter until the discontinuation of study treatment. In addition, the evaluation is 
performed when the subject obtains PR or CR for the first time; if the subject has obtained PR before CR, the evaluation should be performed again when 
CR is obtained. 
[18] 
Concomitant medication: Concomitant medications from 14 days before study treatment to 90 days after the last dose of study treatment will be collected. 
After the last dose, only concomitant medications for treatment-related AEs will be recorded. 
[19] 
AE: As per NCI CTCAE V4.03, all AEs that occur from the signing of the informed consent form to 90 days after the last dose or the start of new anti-
tumor treatment should be observed and documented. From 30 days after the last dose, for non-serious AEs, only those related to the investigational drug, 
including AEs of special interest, will be collected. All AEs should be followed up until Grade 0-1, recovery to baseline levels, or reasonably explained 
(e.g., lost to follow-up or death). 
[20] 
PK blood collection: In Cycle 1, within 0.5 h pre-administration and within 5 min and at 2 h (± 10 min) post-administration on D1, and on D8 (± 60 min). 
In Cycles 2, 4, and 6, within 0.5 h pre-administration and 5 min post-administration on D1 (only for subjects participating in the PK study). 
[21] 
SHR-1210 injection: Record the start and end time of the infusion of the investigational drug. 
[22] 
Survival follow-up: The survival follow-up period will start after the end of the safety follow-up period. Survival follow-up will be conducted once every 
3 months (± 14 days), either via telephone or in -person visit.

 INTRODUCTION: BACKGROUND AND SCIENTIFIC RATIONALE 
2.1. Background 
Hodgkin's lymphoma (HL) is a tumor that originates from lymphocytes, and R-S cells are its 
characteristic pathological manifestation, while painless lymphadenopathy is its common clinical 
manifestation. WHO divides HL into classic Hodgkin's lymphoma (cHL) and nodular 
lymphocyte predominant Hodgkin's lymphoma (NLPHL). According to GLOBOCAN 2012, the 
number of new HL cases is 66,000 per year [1]. The National Cancer Institute of the United 
States estimated that the number of new HL cases in 2016 was about 8500, and the total number 
of HL patients in 2013 was 193,545 [2]. China lacks complete epidemiological data of HL, but 
the National Cancer Center of China estimated that there would be 88,200 new lymphoma 
patients in 2016 [3], and HL accounted for 8.54% of all lymphoma patients [4]. The cause of HL 
is still unknown. The etiology study of Epstein-Barr virus has received the most attention. The 
genome fragments of Epstein-Barr virus can be detected in the RS cells of about half of the 
patients.

The initial treatment of HL can achieve a high cure rate, but 5%-10% of patients are still resistant 
to the initial treatment, and 10%-30% of patients will relapse after a complete response (CR). 
High-dose chemotherapy combined with ASCT is the standard treatment for refractory or 
relapsed HL [5]. HL patients who relapse after ASCT usually have a poor prognosis. Studies 
have reported that the median time to progression (TTP) for treatment after ASCT failure was 
only 3.8 months, and the median overall survival (OS) was 26 months [6]. After ASCT failure, 
the treatment options are very limited. Among the cytotoxic drugs, only vinorelbine and 
gemcitabine show certain activity, but the duration of their effects is relatively short and 
complicated with obvious hematological toxicity. In recent years, some new drugs have also 
been explored in patients with relapsed or refractory HL. The detailed information can be seen in

In foreign countries, brentuximab vedotin has been approved for relapsed HL patients after 
ASCT, and the median OS is 22.4 months [12], while the median PFS of treatment after the 
failure of brentuximab vedotin is only 3.5 months [13]. 
The Science selected cancer immunotherapy as the most important scientific breakthrough in 
2013. In recent years, immune checkpoint inhibitors represented by PD-1/PD-L1 monoclonal 
antibodies have achieved great success in the field of cancer treatment, especially in the 
treatment of melanoma, non-small cell lung cancer, kidney cancer, head and neck cancer, and 
Hodgkin's lymphoma. In a phase Ib clinical study of PD-1 antibody nivolumab developed by 
BMS, among 23 patients with relapsed or refractory cHL who were given 3 mg/kg of nivolumab 
once every 2 weeks, the ORR was as high as 87% and the 24-week PFS rate was 86% [14]. In a 
subsequent phase II study, 80 patients with cHL who failed both ASCT and brentuximab vedotin 
were enrolled and were given 3 mg/kg of nivolumab once every 2 weeks, and the ORR was 
66.3%. The most common treatment-related AEs (≥ 15%) included asthenia (25%), injection 
related reaction (20%), and rash (16%). The most common treatment-related Grade 3/4 AEs 
were neutropenia (5%) and lipase concentration increased (5%). The most common SAE was 
fever [15]. Based on the results of these two trials, the FDA has approved nivolumab for the 
treatment of cHL after ASCT and brentuximab vedotin treatments. Pembrolizumab, a PD-1

antibody from Merck, was investigated in 31 cHL patients who had failed brentuximab vedotin 
treatment in the phase I study, and the patients were given 10 mg/kg of pembrolizumab once 
every 2 weeks, achieving an ORR of 65% (CR 16%, PR 48%) [16]. In a subsequent phase II 
study, pembrolizumab 200 mg was used once every 3 weeks to treat a total of 210 patients with 
relapsed/refractory cHL, with an ORR of about 70% and an proportion of CR of about 20%. The 
FDA has also approved it for the treatment of relapsed or refractory cHL [17]. In China, ASCT 
has not been widely used, and no brentuximab vedotin or PD-1 antibodies have been approved 
for the treatment of HL. Therefore, Chinese HL patients urgently need effective treatment 
options after the failure of initial treatment. 
2.2. Scientific Rationale 
2.2.1. Study rationale 
Programmed death-1 (PD-1) is a protein receptor expressed on the surface of T cells. It binds to 
programmed death-ligand 1 (PD-L1) to transmit inhibitory signals and reduce the proliferation of 
T cells. Many human solid tumors express PD-L1, which is one of the reasons for their evasion 
of immune killing. The genetic variation at the 9p24.1 locus is a feature of malignant cells in 
classic Hodgkin's lymphoma and leads to the overexpression of PD-L1 and immune escape [18]. 
Epstein-Barr virus infection will also increase the expression of PD-L1 in EBV + Hodgkin's 
lymphoma [19]. The overexpression of PD-L1 in Hodgkin's lymphoma may indicate the 
sensitivity of this disease to PD-1 blockade. PD-1 antibodies nivolumab and pembrolizumab 
have shown good efficacy and safety in clinical studies of classic Hodgkin's lymphoma. 
2.2.2. Rationale for drug development 
Hengrui used PD-1 as a target and recombinant PD-1 protein as an immunogen to obtain a series 
of PD-1 antibodies in mice. Through a large number of in vitro binding assays, in vitro ligand 
blocking assays, T cell proliferation assays, animal studies, and antibody druggability 
assessments, an antibody prototype was selected. Then, a humanized design of the murine 
antibody prototype was carried out through computer simulations, resulting in several humanized 
anti-PD-1 monoclonal antibodies. Finally, SHR-1210, an antibody with the highest activity, was 
selected for further development. Preclinical study data showed that SHR-1210 has in vivo and in 
vitro anti-tumor effects similar to those of nivolumab and pembrolizumab on the market. 
Moreover, 3 phase I clinical studies of SHR-1210 are being carried out in Chinese solid tumor 
patients, and the dose escalation phase has been completed. No dose-limiting toxicity was found, 
and the maximum tolerated dose (MTD) was not reached, indicating good tolerability. This study 
aims to further explore the efficacy and safety of SHR-1210 in classic Hodgkin's lymphoma with 
potential benefit.

2.2.3. Basis of dosing regimen 
PD-1 immune checkpoint inhibitors exert their effect on relieving immunosuppression by 
blocking the binding of PD-1/PD-L1. Therefore, the receptor occupancy of these inhibitors is the 
basic pharmacological mechanism that reflects the ultimate anti-tumor effects. Phase I PK 
studies showed that blood concentrations dropped to 1000 ng/mL or below on D15 after a single 
dose of 1 mg/kg and a fixed dose of 60 mg, and remained between 4000-9000 ng/mL after a 
single dose of 3 mg/kg and a fixed dose of 200 mg. Receptor occupancy assays suggested that a 
blood concentration of at least 2000 ng/mL is required to maintain the receptor saturation. 
Clinical results also suggested that a fixed dose of 200 mg every 2 weeks can maintain a 
saturated receptor occupancy. In phase I studies, the incidence of AEs did not increase with the 
dose, whether the drug was administered by weight or by dose fixed. Based on results from the 
studies described above and the convenience of clinical administration, a fixed dose of 200 mg 
every 2 weeks is selected as the treatment regimen for this study. 
2.3. Potential Risks and Benefits 
Relapsed or refractory HL lacks effective treatment drugs. In recent years, studies have found 
that PD-1 antibodies nivolumab and pembrolizumab have shown good efficacy in patients with 
classic Hodgkin's lymphoma, and both nivolumab and pembrolizumab have been approved by 
the FDA for the treatment of relapsed or refractory classic Hodgkin's lymphoma. SHR-1210 is 
a humanized PD-1 antibody independently developed by Hengrui. Preclinical data suggested that 
SHR-1210 has efficacy and anti-tumor effect similar to those of nivolumab and pembrolizumab. 
An ongoing phase I clinical study in China has found that SHR-1210 also shows certain efficacy 
in solid tumors of different types, and it has entered the phase III clinical study. The possible 
benefit for subjects enrolled in this study is partial or complete response. The maintenance of 
stable disease may also be a benefit for subjects with relapsed or refractory cHL. The treatment 
data of these subjects may guide the clinical treatment and development of SHR-1210 for cHL. 
The AEs with a high incidence in phase I studies were mainly reactive cutaneous capillary 
endothelial proliferation, rash, pyrexia, ALT increased, AST increased, and hypothyroidism, but 
most of them were Grade I-II and could be recovered without interrupting the continued use of 
the investigational drug. In addition, subjects undergoing biopsy may be at risk of bleeding and 
pain. For more detailed safety information, please refer to the second edition of SHR-1210 
Investigator's Brochure and Informed Consent Form.

 STUDY DESIGN 
This study adopts an open-label, single-arm, and multi-center design to evaluate the efficacy and 
safety of SHR-1210 in patients with relapsed or refractory classic Hodgkin's lymphoma, and to 
evaluate the PK parameters of 12 subjects at the same time. Sixty subjects who meet the 
enrollment conditions will be enrolled and given SHR-1210 at 200 mg/dose on D1 of each 2-
week cycle, until the following conditions occur: progressive disease (PD), intolerable toxicity, 
or other reasons specified in the protocol. After treatment, the subjects will enter the follow-up 
period to receive safety follow-up or survival follow-up. 
SHR-1210 is an immune checkpoint inhibitor. According to the experience with similar drugs, 
some subjects may experience delayed or early pseudo progression after receiving the 
immunotherapy agents. Therefore, subjects with first PD are allowed to continue to receive 
treatment under the premise of no obvious clinical deterioration per the judgment of the 
condition by the investigators, until PD is still determined in the next imaging evaluation. 
The diagram of study design is shown as follows:

5.3. Study Withdrawal Criteria 
Reasons for withdrawal may include: 
• 
Withdrawal of informed consent and refusal of further follow-ups by subjects; 
• 
Continuing participation in the study is not in the best interests of the patient due to any 
clinical adverse reactions, laboratory abnormalities, or concurrent diseases, as assessed 
by the investigators; 
• 
Other investigator-assessed reasons requiring withdrawal, such as the inability to 
provide voluntary consent due to imprisonment or quarantine; 
• 
Lost to follow-up; 
• 
Death; 
• 
Study termination by the sponsor. 
5.4. Criteria for Treatment Discontinuation 
Criteria for treatment discontinuation are as follows: 
The study treatment must be discontinued when any of the following occurs: 
1. Treatment discontinuation requested by subjects; 
2. Radiographic or clinical evidence of PD, unless the subject meets the criteria for continuing 
treatment after progression; 
3. Occurrence of subject pregnancy during the study; 
4. Any clinical AEs, laboratory abnormalities, or other medical conditions indicating that the 
subject can no longer benefit from the treatment;  
5. Deterioration of the overall health suggesting treatment continuation impossible; 
6. Major protocol deviations such as ineligibility found after enrollment;  
7. Lost to follow-up;

5.5. Procedures for Withdrawal or Discontinuation 
The efficacy and safety examinations to be completed upon study withdrawal as specified in the 
protocol must be completed as much as possible. In addition, the safety follow-up should be 
completed along with fully documented AEs and their outcomes. The investigators can 
recommend or provide new or alternative treatments to a subject based on the condition of the 
subject. Subjects showing no PD need to be continuously followed-up for imaging evaluation 
until the subjects begin new anti-tumor treatment or show PD. 
Subject's survival status should still be followed up even when the subject refuses to visit study 
sites, unless the subject withdraws consent to provide further information or consent to be further 
contacted. In such case, no study assessment is performed, nor any data are collected. 
5.6. Re-Screening Criteria for Subjects 
In this study, re-screening is allowed, i.e., subjects who have entered the screening process but 
have not met the enrollment conditions and have not started treatment may be re-enrolled. When 
re-screening, the informed consent form must be re-signed and a new subject number will be 
given. 
5.7. Premature Termination or Suspension of Study 
This study can be terminated prematurely or suspended if there are sufficient reasons. This may 
result from the decision of the regulatory authorities, changes in comments by the ethics 
committee (EC), efficacy or safety issues of the investigational drug, or the judgment of the 
sponsor. In addition, Hengrui reserves the right to terminate the research and development of 
SHR-1210 at any time. The party who decides to suspend/terminate the study should notify the 
investigators, sponsor, and regulatory authorities in writing, documenting the reasons for 
suspension/termination. The investigators must immediately notify the EC and sponsor, and 
provide relevant reasons. 
The reasons for premature termination or suspension of the study may include: 
• 
Confirmed unexpected, major, or unacceptable risk to the subjects. 
• 
Existing efficacy data supporting premature study termination. 
• 
Poor protocol compliance. 
• 
Incomplete or undetectable measures. 
• 
Valueless study results. 
Once the aforementioned issues involving drug safety, protocol compliance, and data quality are 
resolved, the study can be continued upon approval from the sponsor, EC, or CFDA (now NMPA).

 PHARMACOKINETIC STUDY DESIGN 
6.1. Collection and Processing of Blood Samples 
6.1.1. Blood sampling time 
A PK study will be carried out in 12 subjects enrolled in this study (in Beijing Cancer Hospital, 
the leading site). 
• 
There were 4 blood collection time points for the single dose in Cycle 1: within 0.5 h 
pre-administration on D1, within 5 min and at 2 h (± 10 min) after the end of 
administration on D1, and on D8 (± 60 min); 
• 
Within 0.5 h pre-administration and 5 min post-administration on D1 of Cycles 2, 4, 
and 6. 
6.1.2. Processing and storage of blood samples 
At each of the above time points, 4 mL of venous blood is collected into a serum separation tube 
to obtain the serum, which is then transferred into cryotubes (aliquoted equally into the test tubes 
and backup tubes). The cryotubes are stored in a low temperature freezer at ≤ -60 °C until they 
are transported to the central laboratory for PK testing. Please refer to the Laboratory Manual for 
specific operation details. 
6.2. Shipping of Clinical Samples 
The samples in test tubes should be sent out first in dry ice storage state. The samples in backup 
tubes will be sent out after the bioanalytical laboratory confirms the receipt of the test tube 
samples. Details of shipping frequency and other shipping information are described in the 
Laboratory Manual.

Shelf life: 2 years (tentative) from the date of manufacture 
Storage conditions: sealed, away from light, stored at 2-8 °C in medical refrigerator. Do not 
freeze. 
Label: refer to the pharmacy manual, and the actual label shall prevail 
7.1.3. Storage and stability of investigational drug 
The investigators or the authorized representative thereof (e.g., pharmacist) will ensure that all 
investigational drugs are stored in a secure and access-controlled area conforming to storage 
conditions and regulatory requirements. 
The investigational drug should be stored under the storage conditions listed in Section 7.1.2. 
Where the protocol differs from other information, SHR-1210 will be stored according to the 
storage conditions listed on the label. 
Daily maximum and minimum temperatures of all storage zones (such as cold storage) must be 
recorded by study sites. Documentation should begin with the receipt of the investigational drug 
until the last subject completes the last visit. Even if a continuous monitoring system is 
employed, a written log must be kept to ensure a correct record of storage temperature. The 
temperature monitoring and storage devices (such as refrigerator) should be regularly inspected 
to ensure proper operation. 
Any deviations related to the labeled conditions on the product should be immediately reported 
upon discovery. Study sites should take active measures to restore the investigational drug under 
the storage conditions described on the label, and the temperature deviation and the measures 
taken should be reported to the sponsor. 
Investigational drugs affected by the temperature deviation should be isolated temporarily and 
may only be used after approval by the sponsor, and such case is not considered a protocol

7.1.4. Preparation of investigational drug 
Drugs used in this study are all administered via intravenous drip infusion. Therefore, these 
drugs should be prepared by qualified or experienced study staff such as a study nurse. The 
investigational drug SHR-1210 does not contain preservatives, and must be prepared using 
aseptic technique. Refer to the pharmacy manual for drug preparation. 
7.1.5. Administration of investigational drug 
SHR-1210: 200 mg/dose, intravenous drip infusion over 30 min (not less than 20 min and not 
more than 60 min) on D1 of each 2-week cycle. The treatment will continue until the occurrence 
of confirmed PD, intolerable toxicity, or other reasons specified in the protocol. 
For Cycle 2 and subsequent cycles, the drug can be administered 3 days before or after the day of 
scheduled administration. Administration beyond 3 days after the scheduled dosing day will be 
considered as a dose delay. Subsequent dosing will be carried out based on the actual date of the 
previous dosing. All required examinations and evaluations must be completed prior to each 
dose. 
7.1.6. Dose modification and delay 
7.1.6.1. Dose modification 
AEs related to SHR-1210 may be immune-related AEs (irAEs), and may develop shortly after 
the first dose or months after the last dose. SHR-1210 should be interrupted if events listed in the 
following table occur. During the study, the investigators must consult with the sponsor if, based 
on the benefit to risk ratio of the subject, SHR-1210 should be interrupted or resumed instead of

For patients with metastasis to liver and Grade 2 AST or ALT increased at baseline, treatment should be 
discontinued if a ≥ 50% increase in AST or ALT from baseline persists for at least 1 week. 
For subjects with intolerable or persistent Grade 2 treatment-related AEs, the investigators may consider interrupting 
SHR-1210 treatment if appropriate. For subjects with persistent Grade 2 adverse reactions that fail to return to Grade 
0-1 within 12 weeks after the last dose, treatment should be discontinued. 
7.2. Management, Dispensation, and Return of Investigational Drug 
Designated personnel are responsible for the management, dispensation, and return of 
investigational drugs. The investigators must ensure that all investigational drugs are used by 
enrolled subjects only and the dose and route of administration comply with Section 6.1.5. 
Remaining or expired drugs should be returned to the sponsor and may not be used for non-
participants. 
When the investigational drug is transported to study sites, a drug receipt form should be signed 
by both parties in duplicate, one copy for study sites and the other for the sponsor. When 
returning remaining drugs and empty packaging, both parties must sign the drug return form. The 
dispensation and return of every drug should be immediately documented on designated forms. 
The CRA is responsible for monitoring the supply, use, and storage of investigational drugs, and 
disposal of remaining drugs. 
7.2.1. Disposal of investigational drug 
The sponsor or authorized personnel is responsible for disposing investigational drugs. Drug 
disposal should be well documented.

Live vaccines include but are not limited to, rubeola, epidemic parotitis, rubella, 
chicken pox, yellow fever, rabies, BCG, and typhoid vaccines. Injections of inactivated 
influenza vaccine for seasonal influenza are permitted, but not live attenuated influenza 
vaccines for intranasal use; 
7.4. Recommendations on the Handling of Immune-Related Adverse Events 
Subjects should receive appropriate supportive treatment measures deemed necessary by the 
investigators. Supportive treatment measures for managing immune-related AEs (irAEs) are 
listed below, including oral or intravenous corticosteroids and other anti-inflammatory 
medications when symptoms are not relieved after the use of corticosteroids. Corticosteroids 
may need to be tapered over several cycles since symptoms may worsen during dose reduction. 
Other reasons requiring other supportive treatments, such as metastatic disease or bacterial or 
viral infections, should be ruled out where possible. When the investigators are sure that the AE 
is related to SHR-1210, the supportive treatment listed below may be followed. Otherwise, the 
supportive treatment listed below is not required. 
1. Diarrhea/Colitis 
Subjects should be carefully monitored for signs and symptoms of enterocolitis (such as diarrhea, 
abdominal pain, hematochezia, or mucus stools, with or without pyrexia) and intestinal 
perforations (such as peritonitis and intestinal obstruction). 
 
Subjects with diarrhea/colitis should drink an adequate amount of fluids. Fluids and 
electrolytes should be administered intravenously if adequate oral intake is not possible. 
GI consultation and endoscopy should be considered to confirm or rule out colitis for 
subjects with Grade 2 or greater diarrhea.

· Subjects who discontinue study treatment due to "PD" will begin survival follow-up, 
which will be conducted every 3 months (± 14 days), either via telephone or in-person 
visit. 
· Subjects who discontinue the study treatment due to reasons other than "PD" will 
enter the tumor progression follow-up, and continue to receive tumor evaluation in 
accordance with the efficacy evaluation visit frequency (tumor CT or MRI 
examination, tumor FDG-PET examination) as stipulated in the protocol, until PD, 
start of new anti-tumor treatment, or death; after tumor progression, the survival 
follow-up will be carried out once every 3 months (± 14 days), either via telephone 
or in-person visit. 
8.5. Unscheduled Visit 
The following items should be documented at unscheduled visits for subjects developing AEs 
during the study: 
• 
Results of relevant examinations 
• 
AEs 
• 
Concomitant medications 
8.6. Criteria for Continuing Treatment Beyond Progression 
Some subjects receiving immunotherapy can still benefit clinically after radiographic 
progression. The study treatment may be continued after PD defined per Lugano 2014 criteria for 
subjects who meet the criteria below: 
• 
The investigators deem that it is in the best interest of the subject to continue treatment, 
and subject is not required to start other anti-tumor treatment immediately; 
• 
The subject is able to tolerate continued study treatment 
• 
No significant deterioration in subject's performance status, and no significant 
worsening of cancer-related symptoms 
• 
Before continuing the study treatment, it must be reviewed and approved by the 
medical monitor 
If it is decided that the subject will continue the study treatment after progression, the subject 
should continue to be treated, evaluated, and followed up according to the protocol requirements. 

Compound Name: SHR-1210 
Protocol No.: SHR-1210-II-204 
Version 3.0, Version Date: 19 Jul., 2017 
 
 
Hengrui Confidential 
57 
Subjects should withdraw from study treatment if further progression is observed at the next 
assessment. The initial date of investigator-assessed progression should be used for all statistics 
analyses involving progression, regardless of whether the subject continues the study treatment 
beyond progression. 
If the subject discontinues treatment due to deterioration of the general condition without 
objective evidence for PD, the progression will be reported as "general deterioration". More 
objective evidences (such as imaging confirmation) of progression of these subjects should be 
obtained after treatment discontinuation.  
For subjects who withdraw from the study due to intolerable toxicity without radiographic PD 
observed, the imaging examination should be performed at the same frequency, until PD or start 
of other anti-tumor treatment. The radiographic evidence of PD of these subjects must be 
obtained whenever possible. 
 ASSESSMENTS 
9.1. Assessment of Efficacy 
The Lugano 2014 criteria are used to evaluate the objective response rate (ORR), including the 
CR and PR cases. 
ORR: Defined as the proportion of subjects whose best response reaches CR or PR from the first 
dose to the occurrence of PD or the start of new anti-tumor treatment, whichever comes first 
PFS: Defined as the time from the date of the first dose to the first documented PD or all-cause 
death, whichever occurs first. If the subject has not had PD or died by the data cut-off date, the 
cut-off date is the date of the subject's last efficacy evaluation. If the subject has not received 
tumor evaluation, the cut-off date is the date of the first dose, and PFS lasts for 1 day. 
DoR: Defined as the time from the date of the first CR or PR to the date of initial assessment of 
PD or all-cause death, whichever comes first. If the subject has not had PD or died by the data 
cut-off date, the censoring date is the date of the subject's last efficacy evaluation. Only 
applicable to subjects with CR/PR. 
TTR: Defined as the time from D1 of administration to the first evaluation of PR or CR, 
whichever comes first. Only applicable to subjects with CR/PR. 
9.2. Assessment of Safety 
9.2.1. Safety parameters 
Safety parameters for this study include clinical symptoms, vital signs, physical examination, 
and laboratory tests (hematology, urinalysis, blood biochemistry, thyroid function, coagulation 
function, etc.). 

Compound Name: SHR-1210 
Protocol No.: SHR-1210-II-204 
Version 3.0, Version Date: 19 Jul., 2017 
 
 
Hengrui Confidential 
58 
AEs are evaluated according to NCI CTCAE V4.03, including type, incidence, severity, start and 
end date, whether it is an SAE, correlation with the investigational drug, and outcome. 
AEs that occur during the study, including signs and symptoms at screening, will be recorded in 
the AE page of the electronic case report form (eCRF). 
The latest version of MedDRA is used to medically code the collected AEs, which are finally 
presented in the form of listing. 
9.3. Assessment of Pharmacodynamics 
PK assessment is conducted by measuring the concentration of the parent drug in the blood 
sample, and the PK parameters of SHR-1210 in the human body will be calculated using the 
non-compartmental model. For multiple-dose pharmacokinetics, drug accumulation will be 
studied according to the maximum concentration and minimum concentration in multiple cycles. 
The primary multiple-dose PK parameters will be investigated, mainly including: 
1) Cmax: maximum blood concentration; 
2) Cmin: minimum blood concentration; 
3) Tmax: time to the maximum concentration; 
4) Elimination half-life (t1/2z); 
5) Area under the concentration-time curve (AUC); 
6) Apparent volume of distribution (Vz); 
7) Systemic clearance (CLS). 
 ADVERSE EVENT REPORTING 
10.1. Adverse Event (AE) 
10.1.1. Definition of adverse event 
An AE refers to any untoward medical occurrence in a clinical investigation subject administered 
a pharmaceutical product and which does not necessarily have to have a causal relationship with 
this treatment. In this study, all AEs occurring from signing the informed consent form to 90 days 
after the last dose will be collected. From 30 days after the last dose, for non-serious AEs, only 
those related to the investigational drug will be collected. 
AEs can include any unfavorable and unintended symptoms, signs, laboratory abnormalities, or 
diseases, including the following: 

Compound Name: SHR-1210 
Protocol No.: SHR-1210-II-204 
Version 3.0, Version Date: 19 Jul., 2017 
 
 
Hengrui Confidential 
59 
1) Worsening of pre-existing (prior to entering clinical study) medical conditions/diseases 
(including worsening symptoms, signs, or laboratory abnormalities); 
2) Any new AE: Any new adverse medical conditions (including symptoms, signs, and newly 
diagnosed diseases); 
3) Clinically significant laboratory abnormalities. 
All AEs should be collected in detail by the investigators, including: the name of the AE and 
description of all relevant symptoms, onset time, severity, correlation with the investigational 
drug, duration, measures taken, as well as final results and outcomes. 
10.1.2. AE severity grading criteria 
Please refer to NCI-CTC AE V4.03 for grading criteria. Refer to the following criteria for AEs 
not listed in NCI-CTC AE V4.03: 
Table 3. AE severity grading criteria 
Grade 
Clinical Description of Severity 
1 
Mild; asymptomatic or mild clinical symptoms; clinical or laboratory test abnormality only; 
intervention not indicated 
2 
Moderate; minimal, local, or non-invasive interventions required; limiting age-appropriate 
instrumental activities of daily living (ADL), e.g., cooking, shopping, using the telephone, counting 
money, etc. 
3 
Severe or medically significant symptoms but not immediately life-threatening; hospitalization or 
prolongation of hospitalization indicated; disabling; limiting self-care ADL. Self-care ADL: refer to 
bathing, dressing and undressing, feeding self, using the toilet, taking medications, and not bedridden 
4 
Life-threatening consequences; urgent intervention indicated 
5 
Leading to death 
10.1.3. Determination of the relationship between AEs and investigational drug 
AEs will be collected from the signing of the informed consent form to 90 days after the last 
study dose or the start of new anti-tumor treatment, regardless of whether the event is related to 
the investigational drug or whether any medication is taken against the AE. From 30 days after 
the end of treatment, for non-serious AEs, only those related to the investigational drug will be 
collected. Any discomforts complained by the subject or changes in objective laboratory 
measurements during the treatment period should be faithfully recorded. The severity, duration, 
measures taken, and outcome of AEs should also be documented. The study physician should 
comprehensively assess the relationship between the AE and the investigational drug by 
considering the temporal relationship between the administration of investigational drug and the 
occurrence of AE, the characteristics of the investigational drug, the toxicological and 
pharmacological effects of the investigational drug, concomitant medications, underlying 

Compound Name: SHR-1210 
Protocol No.: SHR-1210-II-204 
Version 3.0, Version Date: 19 Jul., 2017 
 
 
Hengrui Confidential 
60 
diseases, medical history, family history, as well as dechallenge and rechallenge. The causality 
assessment will be provided using the following five categories: "related, possibly related, 
unlikely related, not related, and unassessable". Events that are assessed to be "related", 
"possibly related", and "unassessable" will be listed as adverse drug reactions. When calculating 
the incidence of AEs, the total of these three categories will be used as the numerator and the 
total number of subjects for safety assessments will be used as the denominator. 
10.2. Serious Adverse Event (SAE) 
10.2.1. Definition of SAE 
An SAE refers to a medical occurrence during the study that results in hospitalization, prolonged 
hospitalization, disability, incapacity, life-threatening or death, or congenital malformation. The 
following medical events are included: 
 
Events leading to death; 
 
Life-threatening events (defined as when the subject is at immediate risk of death at the 
time of the event); 
 
Events leading to hospitalization or prolonged hospitalization; 
 
Events leading to permanent or serious disability/incapacity/impairment of work 
ability; 
 
Congenital anomalies or birth defects; 
 
Other important medical events (defined as events that may jeopardize the subject or 
require interventions to prevent any of the above). 
10.2.2. Hospitalization 
AEs leading to hospitalization (even if for less than 24 h) or prolonged hospitalization during the 
clinical study should be considered as SAEs. 
Hospitalization does not include the following: 
 
Hospitalization at a rehabilitation institution 
 
Hospitalization at a sanatorium 
 
General emergency admission 
 
Day surgery (e.g., outpatient/same-day/ambulatory surgery) 
 
Social reasons (medical insurance reimbursement, etc.) 

Compound Name: SHR-1210 
Protocol No.: SHR-1210-II-204 
Version 3.0, Version Date: 19 Jul., 2017 
 
 
Hengrui Confidential 
61 
Hospitalization or prolonged hospitalization unrelated to the worsening of an AE is not an SAE. 
For example: 
 
Hospitalization due to the pre-existing disease without new AEs or aggravation of the 
pre-existing disease (e.g., hospitalization to examine laboratory abnormalities that have 
persisted from before the study until now); 
 
Hospitalization for management reasons (e.g., annual physical examination); 
 
Hospitalization during the study as specified in the study protocol (e.g., as required by 
the protocol); 
 
Elective hospitalization unrelated to worsening of AEs (e.g., elective surgery); 
 
Scheduled treatment or surgery that should be documented throughout the entire study 
protocol and/or in the subjects' individual baseline information; 
 
Hospitalization merely for use of blood products. 
Diagnostic or therapeutic invasive (e.g., surgery) and non-invasive procedures should not be 
reported as AEs. However, when a condition resulting in such procedures meets the definition of 
AE, it should be reported as such. For example, acute appendicitis during the AE reporting 
period should be reported as an AE, and the resulting appendicectomy should be recorded as the 
treatment of the AE. 
10.2.3. Progressive disease 
PD is defined as the worsening of the subject's conditions caused by the indications of the study, 
including radiological progressions and progressions in clinical symptoms and signs. New 
lesions relative to the primary tumor, or progression of the previous lesions, are recognized as 
PD. Life-threatening events, hospitalization or prolonged hospitalization, or events leading to 
permanent or severe disability/incapacity/impairment of work ability, congenital anomalies or 
birth defects arising from the symptoms and signs of PD are not reported as SAEs. Death caused 
by the symptoms and signs of PD will be reported as an SAE. 
10.2.4. Potential drug-induced liver injury 
Drug-induced liver injury will be considered if AST and/or ALT levels are abnormal 
accompanied with abnormal elevation of TBIL, the following criteria are met, and when there 
are no other causes of liver injury. These cases should always be considered as important 
medical events. 

Compound Name: SHR-1210 
Protocol No.: SHR-1210-II-204 
Version 3.0, Version Date: 19 Jul., 2017 
 
 
Hengrui Confidential 
62 
Potential drug-induced liver injury is defined as follows: 
Baseline Period 
Normal (AST/ALT and TBIL) 
Abnormal (AST/ALT and TBIL) 
Treatment Period • 
ALT or AST ≥ 3 × ULN  
• 
With TBIL ≥ 2 × ULN 
• 
And ALP ≤ 2 × ULN 
• 
And no hemolysis 
• 
AST or ALT ≥ 2 × baseline level, and values  
≥ 3 × ULN; or AST or ALT ≥ 8 × ULN 
• 
With TBIL increase ≥ 1 × ULN or TBIL ≥ 3 × ULN 
After being notified of the abnormal results, the subjects should return to study sites for an 
assessment as soon as possible (preferably within 48 h). Assessments include laboratory tests, 
detailed medical history, and physical assessment, and the possibility of hepatic tumor (primary 
or secondary) should be considered. 
Except for the reexaminations of AST and ALT, albumin, creatine kinase, TBIL, direct and 
indirect bilirubin, γ-GT, prothrombin time (PT)/international normalized ratio (INR), and ALP 
should also be examined. Detailed medical history should include history of alcohol use, 
acetaminophen, soft drugs, various supplements, family diseases, occupational exposure, sexual 
behavior, travel, contact with jaundice patients, surgery, blood transfusion, hepatic diseases, and 
allergies. Further tests may include the testing for acute hepatitis A, B, C, and E, and hepatic 
imaging (such as biliary tract). If the above laboratory criteria are confirmed upon re-
examination, the possibility of potential drug-induced liver injury should be considered in the 
absence of any other causes of abnormal liver function, without waiting for all liver function test 
results. Potential drug-induced liver injury should be reported as an SAE. 
10.2.5. Other anti-tumor treatment 
SAEs should be collected from the signing of the informed consent form until 90 days after the 
last dose of the investigational drug. Within 90 days after the last dose, SAEs that occur after the 
start of new anti-tumor treatment should also be reported. 
10.2.6. SAE reporting 
The collection period for SAEs begins with the signing of the informed consent form until 
90 calendar days (inclusive) after the last study dose. In case of an SAE, whether it is an initial 
report or a follow-up report, the investigators must complete the "NMPA Serious Adverse Event 
Report Form" promptly with signature and date provided. The SAE must be reported to the 
provincial, autonomous regional, and municipal drug regulatory authorities, NMPA, and health 
administrations within 24 h of knowing the event. In addition, the sponsor should be notified and 
the event should be reported to the EC in time. The contact information for reporting is shown in 
Table 5.

Protocol No.: SHR-1210-II-204 
Version 3.0, Version Date: 19 Jul., 2017 
 
 
Hengrui Confidential 
63 
SAEs that occur after 90 days post the last study dose are generally not reported unless they are 
suspected to be related to the investigational drug. The symptoms, severity, correlation with the 
investigational drug, time of onset, time of treatment, measures taken, time and method of 
follow-up, and outcome should be documented in detail in the SAE report. If the investigators 
believe that an SAE is not related to the investigational drug but potentially related to study 
conditions (such as the termination of the previous treatment, or comorbidities during the study), 
this causality should be explained in the description section of the SAE report form. If the 
severity of an ongoing SAE or its relationship to the investigational drug changes, a follow-up 
report should be submitted immediately. If an error is found in a previously reported SAE, such 
SAE may be revised, revoked, or downgraded in follow-up reports and reported in accordance 
with the SAE reporting procedure.

Report Form" should also be filled out and reported according to the SAE reporting procedure. 
10.4. Adverse Event of Special Interest 
When an AE of special interest specified in the study protocol occurs, the investigators must fill 
out the "Report Form of Adverse Events of Special Interest for Hengrui Clinical Studies" and 
report to the sponsor within 24 h of being notified. If the AE of special interest is also an SAE, 
the "NMPA Serious Adverse Event Report Form" should also be completed and submitted to the 
relevant authorities according to the SAE reporting procedure. 
• 
Grade ≥ 3 infusion reaction; 
• 
Grade ≥ 2 diarrhea/colitis, uveitis, and interstitial pneumonia; 
• 
Other Grade ≥ 3 immune-related AEs; 
• 
Any events that meet Hy's Law (ALT/AST > 3 × ULN accompanied with TBIL > 2 × 
ULN and without other causes). 
 INDEPENDENT REVIEW 
On-site imaging review will be performed at each study site, and the independent review 
committee (IRC) will perform central review on the primary efficacy endpoint, ORR. 
On-site imaging review will be performed by an experienced and qualified study physician 
designated by each study site. All the imaging data related to efficacy assessment should be 
archived on CD and sent by each study site to the IRC for evaluation at regular intervals. 
Central review will be performed blindly by two independent radiologists. In the event of 
disagreement between these two independent radiologists, a third radiologist should make the 
final judgment. Refer to the IRC Charter for details. 
Radiographic efficacy evaluations will be performed at each study site and by independent 
radiologists according to Lugano 2014 criteria.

 DATA ANALYSIS/STATISTICAL METHODS 
Data analysis will be completed by Hengrui. Data analysis will be carried out without distinction 
of study sites (Data from all participating study sites will be combined). The primary analysis 
will be performed when the last subject has been treated for 6 months. 
Patients who have failed the screening (those who do not receive any treatment despite signing 
informed consent) will not be included in any analysis. However, they will be reported in 
a separate listing. 
Reasons for withdrawal will be summarized and listed. The listing should include: date of first 
and last administration, duration of investigational drug exposure, and date of withdrawal. 
12.1. Sample Size Determination 
This study uses a single-arm design. The primary objective is to evaluate the efficacy of SHR-
1210 in the treatment of relapsed or refractory cHL. The study endpoint is ORR. By referring to 
historical research data and research results of similar products and given the current clinical 
practice requirements, the investigational drug can be judged as effective only when the lower 
limit of the 95% confidence interval for ORR obtained from the study data is greater than 40%. 
Therefore, the sample size for this study is determined based on the following 2 points: 1. the 
exact method (Clopper-Pearson) is used to calculate the 95% confidence interval for ORR; 2. the 
lower limit of the confidence interval is greater than 40%. Assuming that the ORR of SHR-1210 
in the treatment of relapsed or refractory cHL reaches 65%, a power of 92.90% can be obtained 
with 50 subjects. Given a dropout rate of 20%, this study intends to enroll 60 subjects. 
12.2. Statistical Analysis Plan 
Statistical summaries and analytical methods of data collected from this study will be detailed in 
another individual statistical analysis plan (SAP). The finalized SAP will be kept by the sponsor. 
This SAP may contain revisions to the relevant contents in the protocol. However, when the 
revised content involves the main and/or key factors in the protocol, such as the definition of 
endpoints and the corresponding analysis, such a revision should be reflected in the protocol 
amendment version. 
12.3. Statistical Hypothesis and Decision Rules 
The alternative hypothesis of this study is that the ORR of SHR-1210 for relapsed or refractory 
cHL is greater than 40%. A lower limit of the 95% confidence interval for overall ORR greater 
than 40% estimated from the study data indicates that the investigational drug is effective

12.4. Analysis Populations 
This study will involve the following analysis sets or populations: 
 
Informed Consent Set (ICS): all subjects who have signed the informed consent form. 
 
Full Analysis Set (FAS): eligible subjects who have received the investigational drug. 
The FAS is the primary analysis set for efficacy analysis other than the primary efficacy 
endpoint. 
 
Evaluable Set (ES): 
a subset of the FAS, defined as subjects with at least one post-baseline efficacy 
evaluation in the FAS. The ES is the primary analysis set for the primary efficacy 
endpoint ORR 
 
Per-Protocol Set (PPS): a subset of the FAS, defined as subjects in the FAS who have 
experienced no major protocol deviations. PPS is the secondary analysis set for efficacy 
analysis. 
 
Safety Set (SS): all enrolled subjects who have received the investigational drug and 
have post-administration evaluable safety data. SS is the primary analysis set for safety 
analysis. 
 
PK Set (PKS): all enrolled subjects who have received the investigational drug and 
have post-administration evaluable PK data (concentration and/or parameters). 
12.5. Statistical Methods 
The content and methods of analysis in this study will be explained in the following sections 
hierarchically. 
12.5.1. General analysis 
Unless otherwise specified, all data in this study will be summarized using descriptive statistics 
according to the data type. Measurement data will be summarized using mean, standard 
deviation (SD), median, minimum, and maximum; count data and rank data will be summarized 
using frequency and percentage; for time to event data, the Kaplan-Meier method will be used to 
estimate the median time and its overall 95% confidence interval will be calculated. 
12.5.2. Basic analysis 
The basic analysis will be based on the FAS. The analysis will include but is not limited to the 
following: 
 
Subject disposition and populations;

 
Subjects' basic characteristics (including demographics, life history, medical history, 
and medication history); 
 
The analysis of dose interruption, dose reduction, and study withdrawal of subjects as 
well as corresponding reasons. 
Descriptive summary will be made in the form of listing or using the statistical methods listed in 
Section 12.5.1. 
12.5.3. Handling of missing data 
Except for missing dates in this study, missing data will not be processed. PFS and other time to 
event data will be judged according to Hengrui's censoring rules and the censoring time will be 
calculated. Missing date will be processed according to Hengrui's missing date imputation 
criteria. 
12.5.4. Efficacy endpoint analysis 
For the objective response rate (ORR) based on the IRC's and investigators' assessment, point 
estimation will be performed, and the exact method (Clopper-Pearson) will be used to estimate 
the overall 95% confidence interval as its primary analysis. 
For other secondary efficacy endpoints, including duration of response (DoR), progression-free 
survival (PFS), time to response (TTR), and overall survival (OS), the Kaplan-Meier method will 
be used to estimate their median times and the overall 95% confidence intervals will be 
calculated. 
The analysis of the primary efficacy endpoint will be based on the ES, and other efficacy 
analyses will be repeated based on the primary analysis set FAS and secondary analysis set PPS. 
12.5.5. Safety analysis 
The safety analysis will be summarized primarily using descriptive statistics. AEs, treatment-
emergent AEs (TEAEs), SAEs, laboratory data, vital signs, and other data will be statistically 
summarized. Also, the exposure to the investigational drug (including treatment cycle, received 
total dose, and dose intensity) will be statistically summarized. The above data will be analyzed

Classified summary of post-baseline vital sign data and ECG. 
12.5.6. Interim analysis 
This study does not involve an interim analysis. 
12.5.7. Subgroup analysis 
As a supporting analysis for the primary endpoint ORR, this study will analyze the following 
subgroups based on the FAS: age (≤ 45 vs. > 45 years), IPS score (≤ 3 vs. > 4), and baseline 
disease status (relapsed vs. refractory). The analytical method is the same as that of ORR. If 
necessary, the results will be presented with a forest plot. 
12.5.8. Multiple comparison/multiplicity 
This study does not involve conventional hypothesis testing, and the main results will be 
presented in the form of confidence intervals, without involving the issue of multiplicity. 
12.5.9. Statistical analysis of PK 
PK analyses will be based on the PKS, and PK concentration and PK parameters will be 
summarized using descriptive statistics. Apart from the statistics listed in the general analysis, 
PK concentration and PK parameter data will also be summarized descriptively using geometric 
mean (GM), coefficient of variation (CV%), and geometric CV% (GCV%). In addition, for PK 
concentration data, average and median blood concentration-time curves (concentration-time 
curves) on linear scale and semi-logarithmic scale can be plotted, and individual subjects' 
concentration-time curves (linear scale and semi-logarithmic scale) can be plotted at the same 
time. If PK statistical analysis is outsourced, the statistical analysis plan provided independently 
by the vendor shall prevail for the specific statistical analysis and method plan. 
 DATA MANAGEMENT 
13.1. Data Recording 
Data will be collected and managed using the electronic case report form (eCRF). 
13.1.1. Filing of study medical records 
As source documents, the medical records should be completely retained. The investigators 
should be responsible for filling and keeping the study medical record. The subject information 
on the cover of the medical record should be checked each time before filling the record. The 
medical record should be written in a neat and legible way so that the sponsor's CRA could 
verify the data with eCRF during each monitoring visit.

13.1.2. eCRF entry 
Clinical study data will be collected using the HRTAU EDC system. 
Entry: The data in the eCRF are from and should be consistent with the source documents, such 
as the original medical records and laboratory test reports. Any observations or test results in the 
study should be entered in the eCRF in a timely, accurate, complete, clear, normative, and 
verifiable manner. Data should not be changed arbitrarily. All items in eCRF should be filled out, 
with no blank or omission. 
Modification: The system instructions must be followed when correcting the eCRF data as 
needed, and the reason for data correction must be recorded. The logic verification program in 
the system will verify the integrity and logic of the clinical study data entered into the EDC 
system and generate error message prompt for questionable data. PI or clinical research 
coordinator (CRC) is permitted to modify or explain the problematic data. If necessary, multiple 
queries can be raised until the event of problematic data is resolved. 
13.1.3. eCRF review 
The investigators or designated personnel should fill out, review, and submit the eCRF in a 
timely manner. The investigators or clinical research coordinator (CRC) should promptly 
respond to queries raised by CRA, data manager, and medical reviewer. After data cleaning is 
completed, the investigators will sign the completed eCRF for verification. 
13.2. Data Monitoring 
Implemented by: clinical research associate (CRA). 
Monitoring content: To confirm that whether the study protocol is adhered to; whether the 
records in eCRF are correct and complete, and consistent with the source documents such as 
study medical records and laboratory test reports, and whether there are errors or omissions in 
the data. According to the monitoring plan, the CRA will verify the completeness, consistency, 
and accuracy of study data in the database. The CRA will discuss any queries with study personnel 
and direct them to add or correct the data whenever necessary. Ensure that the data in the eCRF 
are consistent with source data. This process is also known as source data verification (SDV). 
13.3. Data Management 
13.3.1. EDC database establishment 
The data manager will establish a study data collection system and database according to the 
study protocol, which will be available for online usage before the first subject is enrolled. 
Before use, all EDC users should receive adequate training and get the corresponding account to 
log into the system.

13.3.2. Data entry and verification 
The investigators or CRC should input data into the EDC system in accordance with the 
requirements of the visit procedures and the eCRF completion guide. After submitting the eCRF, 
the CRA, data manager, and medical personnel should review the data. Questions during the 
review will be submitted to the investigators or CRC in the form of queries. After data cleaning 
is completed, the investigators should sign the completed eCRF for verification. 
13.3.3. Database lock 
After SDV is completed by CRA, data manager and medical reviewer will conduct the final 
quality control of all data in the database, summarize all protocol deviations during the study, 
and hold a data verification meeting. The database will be locked after quality requirements are 
met. The data manager will export the data to the statistics department for data analysis. 
13.3.4. Data archiving 
After the study is completed, subjects' eCRFs in PDF format must be generated from the EDC 
system and kept in CD-ROMs. These CD-ROMs will be archived by the sponsor and various 
institutions for auditing and/or inspection. 
All materials should be preserved and managed in accordance with GCP requirements, and 
essential documents of clinical studies should be preserved until 2 years after the investigational 
drug is approved for marketing or 5 years after the termination of the clinical study. 
13.3.5. Protocol deviation 
Protocol deviation refers to any practice that does not comply with study protocol or GCP. This 
non-compliance may occur in the subject and may also occur in the investigators or other study 
personnel. Study sites should prepare corresponding corrective measures and implement them 
immediately if a protocol deviation occurs. 
Study sites have the responsibility to maintain constant vigilance, complete the identification of 
protocol deviations in a timely manner, and complete the actions required by the protocol, to 
identify and report protocol deviations in a timely manner. All protocol deviations must be 
documented in the source documents. Protocol deviations must be submitted to local IRB in 
accordance with local ethical regulations. The principal investigators or study personnel of study 
sites are responsible for understanding and complying with local ethical standards.

CR 
CMR (complete metabolic response) 
CRR (complete radiologic response) 
Lymph nodes and 
extranodal sites 
Score 1, 2, or 3 with or without a residual 
mass on PET 5-point scale. It is recognized 
that in Waldeyer's ring or extranodal sites 
with high physiologic uptake or with 
activation within spleen or marrow (e.g., 
with chemotherapy or myeloid colony-
stimulating factors), uptake may be greater 
than normal mediastinum and/or liver. In 
this circumstance, complete metabolic 
response may be inferred if uptake at sites 
of initial involvement is no greater than 
surrounding normal tissue even if the tissue 
has high physiologic uptake. 
Target nodes/nodal masses must regress to 
≤ 1.5 cm in LDi 
No extranodal sites of disease 
Nonmeasured lesions 
Not applicable 
Absent 
Organ enlargement 
Not applicable 
Regress to normal 
New lesions 
None

No evidence of FDG-avid disease in 
marrow 
Normal by morphology; if indeterminate, 
IHC negative 
PR 
PMR (partial metabolic response) 
PRR (partial radiologic response) 
Lymph nodes and 
extranodal sites 
Score 4 or 5 with reduced uptake compared 
with baseline and residual mass(es) of any 
size. 
At interim, these findings suggest 
responding disease 
At end of treatment, these findings indicate 
residual disease 
≥ 50% decrease in SPD of up to 6 target 
measurable nodes and extranodal sites; 
when a lesion is too small to measure on 
CT, assign 5 mm × 5 mm as the default 
value; when no longer visible, 0 × 0 mm; 
for a node > 5 mm × 5 mm, but smaller 
than normal, use actual measurement for 
calculation; 
Nonmeasured lesions 
Not applicable 
Absent/normal, regressed, but no increase 
Organ enlargement 
Not applicable 
Spleen must have regressed by > 50% in 
length beyond normal 
New lesions 
None 
None 
Bone marrow 
Residual uptake higher than uptake in 
normal marrow but reduced compared with 
baseline (diffuse uptake compatible with 
reactive changes from chemotherapy 
allowed). If there are persistent focal 
changes in the marrow in the context of 
a nodal response, consideration should be 
given to further evaluation with MRI or 
biopsy or an interval scan.

Metabolic progression 
Radiologic progression 
Individual target 
nodes/nodal masses and 
extranodal lesions 
Score 4 or 5 with an increase in intensity of 
uptake from baseline and/or 
New FDG-avid foci consistent with 
lymphoma at interim or end-of-treatment 
assessment.  
An individual node/lesion must be 
abnormal with: 
LDi > 1.5 cm and 
Increase by ≥ 50% from PPD nadir and 
An increase in LDi or SDi from nadir 
0.5 cm for lesions ≤ 2 cm 
1.0 cm for lesions > 2 cm; 
In the setting of splenomegaly, the splenic 
length must increase by > 50% of the 
extent of its prior increase beyond baseline 
(e.g., a 15-cm spleen must increase to  
> 16 cm); if no prior splenomegaly, must 
increase by at least 2 cm from baseline; 
New or recurrent splenomegaly. 
Nonmeasured lesions 
None 
New or clear progression of preexisting 
nonmeasured lesions 
New lesions 
New FDG-avid foci consistent with 
lymphoma rather than another etiology 
(e.g., infection, inflammation). If uncertain 
regarding etiology of new lesions, biopsy or 
interval scan may be considered 
A new node > 1.5 cm in any axis; a new 
extranodal site > 1.0 cm in any axis; if  
< 1.0 cm in any axis, its presence must be 
unequivocal and must be attributable to 
lymphoma; 
Assessable disease of any size 
unequivocally attributable to lymphoma 
Bone marrow 
New or recurrent FDG-avid foci 
New or recurrent involvement 
CR = complete response; PR = partial response; SD = stable disease; PD = progressive disease;  
SPD: sum of the product of the perpendicular diameters for multiple lesions; PPD: cross product of the LDi and 
perpendicular diameter; LDi: longest transverse diameter of a lesion; SDi: shortest axis perpendicular to the LDi
