简要总结
The purpose of the study is to compare the efficacy of Ipilimumab and standard of care as sequential or maintenance treatment immediately after first-line chemotherapy in the treatment of unresectable or metastatic gastric and gastro-esophageal cancer.

结局指标
主要结局
Immune-related Progression Free Survival (irPFS) as Per Assessment of a Blinded Independent Review Committee (IRC) According to Immune Related Response Criteria (irRC) Guidelines
时间窗: Randomization up to 91 irPFS events (Approximately 19 months )
irPFS is defined as the time between the randomization date and the time of disease progression per irRC or death, whichever occurs first. irRC criteria=Measurable new lesions: incorporated into the tumor burden (eg, added to the index lesions); do not define progression unless the total measurable tumor burden increases by the required amount (25%). New non-measurable lesions: not considered progression if the total measurable tumor burden is stable or shrinking. irPFS was measured in months.
次要结局
- Progression Free Survival (PFS) Per Modified World Health Organization (mWHO) Criteria(Randomization up to 91 irPFS events (Approximately 19 months ))
- Overall Survival (OS) at Primary Endpoint(Randomization up to 91 irPFS events (Approximately 19 months))
- Overall Survival (OS) at Study Completion(Randomization up to end of study, April 2015 (Approximately 28 months))
- Percentage of Participants With Immune-Related Best Overall Response (irBOR)(Randomization up to 91 irPFS events (Approximately 19 months))
