Clinical Trial Summary

This is a study of Camrelizumab (SHR-1210) and Apatinb for unresectable Recurrent or metastatic alpha-fetoprotein (AFP)-producing gastric cancer or Gastroesophageal Junction Adenocarcinoma. Camrelizumab combined with Apatinib and standard chemotherapy will be given to treatment-naïve participants; Camrelizumab combined with Apatinib will also be evaluated in participants who have had ≥ 1 line of previous treatment. The primary endpoint is the Overall Response Rate (ORR).

Description:

This study will have 2 cohorts. In Cohort 1, participants who have not received any previous therapy for their disease will receive Camrelizumab and Apatinib in combination with Oxaliplatin and S-1. In Cohort 2, participants who have received at least one prior therapy for their advanced disease will receive Camrelizumab and Apatinib. A Simon two-stage phase II design was used for the sample size Calculation.

12. Patients have a deficiency of dihydropyrimidine dehydrogenase (DPD) will be excluded from cohort 1

13. Have any contraindications for study treatment

14. Patients with a history of prior treatment with Apatinib or any anti-PD-1, anti-PD-L1 agent

15. Urinary protein is more than 2+ and 24-hour urine protein > 1.0g

16. Patients with active hepatitis B (HBsAg positive and HBV DNA=500 IU/ml), hepatitis C (HCV antibodies positive and HCV RNA copies > ULN); with active infection requiring drug intervention

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Objective Response Rate (ORR) According to RECIST 1.1 based on investigator assessment	ORR was defined as the percentage of the participants in the analysis population who had a confirmed CR or PR according to RECIST 1.1 based on investigator assessment.	Up to approximately 24 months
Secondary	Objective Response Rate (ORR) According to iRECIST 1.1 based on investigator assessment	ORR was defined as the percentage of the participants in the analysis population who had a confirmed CR or PR according to iRECIST 1.1 based on investigator assessment.	Up to approximately 24 months
Secondary	Disease Control Rate (DCR) According to RECIST 1.1 based on investigator assessment	DCR was defined as the percentage of the participants in the analysis population who had a confirmed CR or PR or SD according to RECIST 1.1 based on investigator assessment.	Up to approximately 24 months
Secondary	Duration of Response (DOR) According to RECIST 1.1 Based on investigator assessment	DOR was defined as the time from first documented evidence of CR or PR until disease progression (according to RECIST 1.1 )or death due to any cause, whichever occurs first.	Up to approximately 24 months
Secondary	Progression-free Survival (PFS) According to RECIST 1.1 base on investigator assessment	PFS was defined as the time from randomization to the first documented disease progression per RECIST 1.1 based on investigator assessment, or death due to any cause, whichever occurs first.	Up to approximately 24 months
Secondary	Disease Control Rate (DCR) According to iRECIST 1.1 base on investigator assessment	DCR was defined as the percentage of the participants in the analysis population who had a confirmed CR or PR or SD according to iRECIST 1.1 based on investigator assessment.	Up to approximately 24 months
Secondary	Duration of Response (DOR) According to iRECIST 1.1 base on investigator assessment	DOR was defined as the time from first documented evidence of CR or PR until disease progression (according to iRECIST 1.1) or death due to any cause, whichever occurs first.	Up to approximately 24 months
Secondary	Progression-free Survival (PFS) According to iRECIST 1.1 base on investigator assessment	PFS was defined as the time from randomization to the first documented disease progression per iRECIST 1.1 based on investigator assessment, or death due to any cause, whichever occurs first.	Up to approximately 24 months
Secondary	Overall Survival (OS)	OS was defined as the time from randomization to death due to any cause.	Up to approximately 24 months
Secondary	Number of Participants Experiencing an Adverse Event (AE)	An AE was defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which did not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavourable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening of a pre-existing condition that was temporally associated with the use of the Sponsor's product was also an adverse event. The number of participants who experienced an AE was reported for each arm according to the treatment received. The grade of AE will be assessed per CTCAE 5.0.	Up to approximately 27 months
