  • Change from Baseline in the European Organization for the Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire C30 (QLQ-C30) Score in All Participants [ Time Frame: Baseline, approximately 1 year ]
    The EORTC QLQ-C30 was developed to assess the quality of life of patients with cancer. It contains 30 questions (items), 24 of which aggregate into nine multi-item scales representing various aspects, or dimensions, of quality of life (QOL): one global scale, five functional scales (physical, role, cognitive, emotional, and social), 3 symptom scales (fatigue, nausea, pain), and six additional single-symptom items assessing additional symptoms commonly reported by cancer patients (dyspnoea, loss of appetite, insomnia, constipation and diarrhoea) and perceived financial impact of the disease. Individual items are scored on a 4-point scale (1=not at all, 2=a little, 3=quite a bit, 4=very much). Raw scores for each scale are standardized into a range of 0 to 100 by linear transformation; a higher score on the global and functional scales represents a higher ("better") level of functioning, and a higher score on the symptom scale represents a higher ("worse") level of symptoms.

Brief Title  ICMJE First-line Esophageal Carcinoma Study With Chemo vs. Chemo Plus Pembrolizumab (MK-3475-590/KEYNOTE-590)
Official Title  ICMJE 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)
Brief Summary

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 overall primary efficacy hypotheses are as follows:

  1. In participants with esophageal squamous cell carcinoma (ESCC), participants whose tumors are programmed cell death-ligand 1 (PD-L1)-positive (defined as combined positive score [CPS] ≥10), ESCC participants whose tumors are PD-L1 positive (CPS ≥10), and in all participants, overall survival (OS) is superior with pembrolizumab plus chemotherapy compared with placebo plus chemotherapy.
  2. In participants with ESCC, participants whose tumors are PD-L1 positive (CPS ≥10), and in all participants, progression-free survival (PFS) according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 as assessed by investigator is superior with pembrolizumab plus chemotherapy compared with placebo plus chemotherapy.
