Brief Title: First-line Esophageal Carcinoma Study With Chemo vs. Chemo Plus Pembrolizumab (MK-3475-590/KEYNOTE-590)-China Extension Study
Official Title: A Randomized, Double-Blind, Placebo-Controlled Phase III Clinical Trial of Pembrolizumab (MK-3475) in Combination With Cisplatin and 5-Fluorouracil Versus Placebo in Combination With Cisplatin and 5-Fluorouracil as First-Line Treatment in Subjects With Advanced/Metastatic Esophageal Carcinoma (KEYNOTE-590)
Study ID: NCT03881111
Brief Summary: The purpose of this Chinese extension study 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 a Chinese cohort of 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 Chinese participants as well as Chinese participants whose tumors are programmed cell death-ligand 1 (PD-L1)-positive.
Detailed Description: The Chinese extension to MK-3475-590 (NCT03189719) will enroll a total of approximately 90 participants.
