ClinicalTrials.gov Identifier:
NCT02335411
First received: January 7, 2015
Last updated: March 7, 2017
Last verified: March 2017
  Purpose
This is a study of pembrolizumab 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.

Condition Intervention Phase
Gastric Adenocarcinoma Gastroesophageal Junction Adenocarcinoma Biological: pembrolizumab Drug: cisplatin Drug: 5-FU Drug: capecitabine Phase 2

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase II Clinical Trial of Pembrolizumab as Monotherapy and in Combination With Cisplatin+5-Fluorouracil in Subjects With Recurrent or Metastatic Gastric or Gastroesophageal Junction Adenocarcinoma (KEYNOTE-059)

Study Start Date: February 2015
Estimated Study Completion Date: June 2018
Primary Completion Date: November 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Cohort 1: Pembro monotherapy, previously treated
Participants receive pembrolizumab 200 mg intravenously (IV) on Day 1 of each 3-week cycle (Q3W) for up to 24 months
Biological: pembrolizumab
Experimental: Cohort 2: Pembro combination therapy, treatment naive
Participants receive pembrolizumab 200 mg IV Q3W for up to 24 months + cisplatin 80 mg/m^2 IV Q3W for up to 6 cycles + 5-FU 800 mg/m^2 IV on Days 1-5 every 3 weeks or (Japan only) capecitabine 1000 mg/m^2 orally, twice per day (BID) on Days 1-14 of each 3 week cycle
Biological: pembrolizumab Drug: cisplatin Drug: 5-FU Drug: capecitabine
Experimental: Cohort 3: Pembro monotherapy, treatment naive
Participants receive pembrolizumab 200 mg IV Q3W for up to 24 months
Biological: pembrolizumab

Detailed Description:
This study will have 3 cohorts. Cohorts 1 and 2 will run simultaneously; Cohort 3 will start when biomarker assay validation is complete. In Cohort 1, participants who have received at least two prior therapies for their advanced disease will receive monotherapy with pembrolizumab. In Cohort 2, participants who have not received any previous therapy for their disease will receive pembrolizumab in combination with cisplatin and 5-FU or (Japan only) capecitabine. In Cohort 3, participants who have not received any previous therapy and who have programmed cell death ligand 1 (PD-L1)-positive tumors will receive monotherapy with pembrolizumab.
