Overview
Brief Summary
This 2 arm study will compare the efficacy and safety of bevacizumab in combination with capecitabine and cisplatin versus placebo in combination with capecitabine and cisplatin in participants who have not received prior chemotherapy for advanced or metastatic gastric cancer. Participants will be randomized to one of two treatment groups Bevacizumab + Capecitabine/Cisplatin (experimental arm) or Placebo + Capecitabine/Cisplatin (control arm).

Arms & Interventions
Bevacizumab, Capecitabine and Cisplatin

Outcomes
Primary Outcomes
Percentage of Participants With Event (Death)
Time Frame: From randomization until death (up to 34 months)
Percentage of participants who died due to any cause was reported. As planned, ad hoc analysis was done for overall survival up to clinical cut-off date of 12 January 2012 (34 months), subsequent to the protocol-defined clinical cut-off date of 13 May 2011 (26 months). Overall survival was defined as the time between randomization and the date of death due to any cause.
Overall Survival
Time Frame: From randomization until death (up to 34 months)
Overall survival was defined as the time between randomization and the date of death due to any cause. Overall survival was estimated using Kaplan Meier method. Reported data included censored observations. Participants for whom no death was captured on the clinical database were censored at the most recent date they were known to be alive. As planned, ad hoc analysis was done for overall survival up to clinical clinical cut-off date of 12 January 2012 (34 months), subsequent to the protocol-defined clinical cut-off date of 13 May 2011 (26 months).
