A Study of Pertuzumab in Combination With Trastuzumab and Chemotherapy in Participants With Human Epidermal Growth Factor Receptor 2 (HER2)-Positive Metastatic Gastroesophageal Junction or Gastric Cancer

This double-blind, placebo-controlled, randomized, multicenter, international, parallel arm study will evaluate the efficacy and safety of pertuzumab in combination with trastuzumab, fluoropyrimidine and cisplatin as first-line treatment in participants with HER2-positive metastatic gastroesophageal junction (GEJ) or gastric cancer (GC). Participants will be randomized to receive pertuzumab 840 milligrams (mg) or placebo intravenously every 3 weeks (q3w) in combination with trastuzumab (initial dose of 8 milligrams per kilogram [mg/kg] intravenously [IV] followed by 6 mg/kg IV q3w) and cisplatin and fluoropyrimidine (capecitabine or 5-fluorouracil) for the first 6 treatment cycles. Participants will continue to receive pertuzumab or placebo and trastuzumab until disease progression occurrence of unacceptable toxicity or withdrawal from the study for another reason.

Stanford is currently not accepting patients for this trial.
