Current Primary Outcome Measures  ICMJE
 (submitted: October 4, 2017)
  • Overall Survival (OS) [ Time Frame: Up to approximately 2 years ]
    OS is the time from randomization to death due to any cause.
  • Progression-free Survival (PFS) [ Time Frame: Up to approximately 2 years ]
    PFS is the time from randomization to first documented disease progression per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) by Blinded Independent Central Review (BICR).

Current Secondary Outcome Measures  ICMJE
 (submitted: October 4, 2017)
  • Objective Response Rate (ORR) [ Time Frame: Up to approximately 2 years ]
    ORR is the proportion of the participants who achieve complete response (CR) or partial response (PR) per RECIST 1.1 by BICR.
  • Duration Of Response (DOR) [ Time Frame: Up to approximately 2 years ]
    DOR is the time from first documented evidence of CR or PR per RECIST 1.1 by BICR until disease progression per RECIST 1.1 by BICR or death.
  • Time to True Deterioration (TTD) in Cough, Pain in Chest, and Shortness of Breath [ Time Frame: On study day 1 prior to initiation of study therapy (baseline) and up to approximately 2 years ]
    Time to true deterioration is defined as the time to the first onset of a 10-point or greater score decrease from study day 1 prior to initiation of study therapy (baseline) in any one of the 3 symptoms, confirmed by a second adjacent 10-point or greater score decrease from baseline. Cough is based on European Organization for Research and Treatment of Cancer Quality of Life Questionnaire and Lung Cancer Module 13 (EORTC QLQ-LC13) question 1, pain in chest is based on EORTC QLQ-LC13 question 10, and shortness of breath is based on European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) question 8.
  • Incidence of Adverse Events (AEs) [ Time Frame: From time of signing the informed consent form (ICF) until the end of follow-up (up to approximately 118 Weeks). ]
    Percentage of participants experiencing any unfavorable and unintended sign, symptom, disease, or worsening of pre-existing condition temporally associated with study therapy and irrespective of causality to study therapy.
  • Incidence of Discontinuations [ Time Frame: From time of signing the ICF until the end of study therapy (up to approximately 105 Weeks). ]
    Percentage of participants discontinuing study drug due to an AE.

Descriptive Information
Brief Title  ICMJE Study of Pembrolizumab Given With Ipilimumab or Placebo in Participants With Untreated Metastatic Non-small Cell Lung Cancer (MK-3475-598/KEYNOTE-598)
Official Title  ICMJE A Phase 3, Randomized, Double-Blind Study of Pembrolizumab Plus Ipilimumab vs Pembrolizumab Plus Placebo in Previously Untreated, Stage IV, Metastatic Non-small Cell Lung Cancer Subjects Whose Tumors Are PD-L1 Positive (TPS ≥ 50%) (KEYNOTE-598)
Brief Summary The purpose of this study is to determine the efficacy of pembrolizumab given in combination with either ipilimumab or placebo as first-line treatment in participants with metastatic non-small cell lung cancer (NSCLC). The primary hypothesis of this study is that overall survival (OS) and/or progression-free survival (PFS) is prolonged in participants who receive pembrolizumab and ipilimumab compared to those who receive pembrolizumab and placebo.
