A Study of Pembrolizumab (MK-3475) in Participants With Recurrent or Metastatic Gastric or Gastroesophageal Junction Adenocarcinoma (MK-3475-059/KEYNOTE-059)

Summary

This is a study of pembrolizumab (MK-3475) for advanced gastric or gastroesophageal junction adenocarcinoma; pembrolizumab will be given as monotherapy to participants who have had previous treatment or who are treatment-naïve; pembrolizumab will also be evaluated as combination therapy with cisplatin and 5-Fluorouracil (5-FU) or (Japan only) capecitabine in treatment-naïve participants. The primary study hypothesis is that pembrolizumab will provide a clinically meaningful Overall Response Rate (ORR).
