Clinical Trial Summary

The purpose of this trial is to estimate overall response rate (ORR) of SHR-1210 combined with capecitabine and oxaliplatin or with apatinib as first-line treatment in subjects with locally advanced or metastatic gastric or gastroesophageal junction (GEJ) adenocarcinoma.

Description:

Approximately 110 participants will be assigned to SHR-1210 + capecitabine + oxaliplatin combination therapy (Cohort 1), or SHR-1210 + apatinib combination therapy (Cohort 2).

Recruitment information / eligibility

• Enrollment: 67
• Est. completion date: November 25, 2020
• Est. primary completion date: November 25, 2020
• Accepts healthy volunteers: No
• Gender: All
• Age group: 18 Years and older

Eligibility

Inclusion Criteria:

• Has histologically- or cytologically-confirmed diagnosis of locally advanced unresectable or metastatic adenocarcinoma of stomach or the esophagogastric junction (GEJ).

• Age = 18 years old, male or female.

• NO previous therapy for advanced/metastatic disease of GC/GEJ (including HER2 inhibitor). Subjects with previous adjuvant/neo-adjuvant therapy completed more than 6 months can be enrolled.

• Has measurable disease per RECIST 1.1.

• Life expectancy = 12 weeks.

• Eastern Cooperative Group (ECOG) performance status of 0 to 1.

• Has adequate organ function.

• Females of childbearing potential (FOCBP), who are not surgically sterile or postmenopausal, must conduct pregnancy test (serum or urine) within 7 days before enrollment, and must not be pregnant or breast-feeding women. If the result is negative, she must agree to use adequate contraception during the experiment and 3 months after the last administration of the test drugs. And non-sterilized males who are sexually active must agree to use adequate contraception during the experiment and 3 months after the last administration of the test drugs.

Exclusion Criteria:

• Has known HER2-positive status.

• Has received prior therapy with an anti-PD-1, anti-PD-L1, or anti-CTLA-4 antibody, or a VEGFR inhibitor.

• Has known active central nervous system metastases.

• Has received a live vaccine within 4 weeks prior to the first dose of study treatment.

• With any active autoimmune disease or history of autoimmune disease, including but not limited to the following: hepatitis, pneumonitis, uveitis, colitis (inflammatory bowel disease), hypophysitis, vasculitis, nephritis, hyperthyroidism, and hypothyroidism, except for subjects with vitiligo or resolved childhood asthma/atopy. Asthma that requires intermittent use of bronchodilators or other medical intervention should also be excluded.

• Clinically significant cardiovascular and cerebrovascular diseases, including but not limited to severe acute myocardial infarction within 6 months before enrollment, unstable or severe angina, Congestive heart failure (New York heart association (NYHA) class > 2), or ventricular arrhythmia which need medical intervention.

• Hypertension and unable to be controlled within normal level following treatment of anti-hypertension agents(within 3 months): systolic blood pressure > 140 mmHg, diastolic blood pressure > 90 mmHg.

• Coagulation abnormalities (INR > 1.5 or APTT > 1.5×ULN), with bleeding tendency or are receiving thrombolytic or anticoagulant therapy.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Objective Response Rate (ORR) Per Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1	ORR is defined as the percentage of participants in the analysis population who have a Complete Response (CR: Disappearance of all target lesions) or a Partial Response (PR: =30% decrease in the sum of diameters of target lesions) per RECIST 1.1.	Up to approximately 6 months.
Secondary	Progression-free Survival (PFS) Per RECIST 1.1	PFS is defined as the time from randomization to the first documented disease progression per RECIST 1.1 based on blinded independent central review or death due to any cause, whichever occurs first.	Up to 24 months.
Secondary	Duration of Response (DOR) Per RECIST 1.1	For participants who demonstrate CR (disappearance of all target lesions) or PR (=30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters), DOR is defined as the time from first documented evidence of CR or PR until disease progression per RECIST 1.1 based on assessments by blinded independent central review or death due to any cause, whichever occurs first.	Up to 24 months.
Secondary	Disease Control Rate (DCR) Per RECIST 1.1	DCR is defined as the percentage of participants in the analysis population who have a CR, PR or SD per RECIST 1.1.	Up to 24 months.
Secondary	Number of Subjects With Treatment-related Adverse Events (AEs)	Incidence, nature, and severity of adverse events graded according to the NCI CTCAE v4.03.	Up to 24 months.
