Study of Pembrolizumab in Previously-Treated Participants With Advanced Carcinoma of the Esophagus or Esophagogastric Junction

In this study participants with advanced/metastatic adenocarcinoma or squamous cell carcinoma of the esophagus or advanced/metastatic Siewert type I adenocarcinoma of the gastroesophageal junction (GEJ) previously treated with two standard therapies will be treated with pembrolizumab.

Study of Pembrolizumab Versus Investigator's Choice Standard Therapy for Participants With Advanced Esophageal/Esophagogastric Junction Carcinoma That Progressed After First-Line Therapy

In this study, participants with advanced or metastatic adenocarcinoma or squamous cell carcinoma of the esophagus or Siewert type I adenocarcinoma of the esophagogastric junction (EGJ) that has progressed after first-line standard therapy will be randomized to receive either single agent pembrolizumab or the Investigator's choice of standard therapy with paclitaxel, docetaxel, or irinotecan. The primary study hypothesis is that treatment with pembrolizumab will prolong progression-free survival (PFS) and/or overall survival (OS) as compared to treatment with standard therapy.

First-line Esophageal Carcinoma Study With Chemo vs. Chemo Plus Pembrolizumab

The purpose of this trial is to evaluate efficacy and safety of pembrolizumab plus cisplatin and 5-fluorouracil (5-FU) chemotherapy versus placebo plus cisplatin and 5-FU chemotherapy as first-line treatment in participants with locally advanced or metastatic esophageal carcinoma. The primary efficacy hypotheses are that both progression-free survival (PFS), according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 and determined by blinded independent central review, and overall survival (OS) are superior with pembrolizumab plus chemotherapy compared with placebo plus chemotherapy in all participants as well as participants whose tumors are gene expression profile (GEP) biomarker-positive.
