简要总结
This randomized, multicenter, open-label study will evaluate two different doses of pertuzumab in combination with Herceptin (trastuzumab) and chemotherapy in the first-line treatment of participants with metastatic HER2-positive adenocarcinoma of the stomach or gastroesophageal junction. Participants will be randomized in a 1:1 ratio to two treatment arms. Participants in the Pertuzumab 840/420 mg Arm will receive a pertuzumab loading dose of 840 mg for Cycle 1 and a dose of 420 mg for Cycles 2-6, and participants in the Pertuzumab 840/840 mg Arm will receive pertuzumab 840 mg for all six cycles. Participants in both treatment arms will receive trastuzumab, cisplatin, and capecitabine.

研究组 & 干预措施
Pertuzumab 840/420 mg
Participants received pertuzumab as an intravenous (IV) infusion at a loading dose of 840 milligrams (mg) for cycle 1 and a dose of 420 mg every three weeks (Q3W) for cycles 2-6. Participants in both arms received trastuzumab, cisplatin, and capecitabine. Capecitabine 1000 milligram per meter squared (mg/m^2) was administered orally twice daily, from the evening of Day 1 to the morning of Day 15 of each cycle. Cisplatin 80 mg/m^2 was administered as an IV infusion on Day 1 of each cycle. Trastuzumab was administered as an IV infusion at a loading dose of 8 mg/kg for Cycle 1 and a dose of 6 milligram per kilogram (mg/kg) Q3W for subsequent cycles.
