Summary:

      The purpose of this study was to evaluate the efficacy and safety of pembrolizumab plus
      epacadostat with platinum-based chemotherapy versus pembrolizumab plus platinum-based
      chemotherapy plus placebo as first-line therapy in participants with metastatic non-small
      cell lung cancer (NSCLC).
    

Eligibility criteria:

        Inclusion Criteria:

          -  Histologically or cytologically confirmed diagnosis of stage IV NSCLC without
             epidermal growth factor receptor (EGFR)-sensitizing mutation, ROS1 and/or anaplastic
             lymphoma kinase (ALK) translocation

          -  Measurable disease based on RECIST 1.1

          -  Life expectancy of at least 3 months.

          -  Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.

          -  Adequate organ function per protocol-defined criteria.

          -  Provide tumor tissue sample.

        Exclusion Criteria:

          -  Known untreated central nervous system metastases and/or carcinomatous meningitis

          -  History of (non-infectious) pneumonitis that required systemic steroids or current
             pneumonitis/interstitial lung disease.

          -  Symptomatic ascites or pleural effusion.

          -  Known history of an additional malignancy, except if the participant has undergone
             potentially curative therapy with no evidence of that disease recurrence for 5 years
             since initiation of that therapy.

          -  Active autoimmune disease that has required systemic treatment in past 2 years.

          -  Has had an allogeneic tissue/solid organ transplant.

          -  Has a known history of human immunodeficiency virus (HIV) infection. HIV testing is
             not required unless mandated by the local health authority.

          -  Has known history of or is positive for active Hepatitis B (HBsAg reactive) or has
             active Hepatitis C (HCV RNA). Note: Testing must be performed to determine
             eligibility.

          -  History or presence of an abnormal electrocardiogram (ECG) that, in the Investigator's
             opinion, is clinically meaningful.

          -  Use of protocol-defined prior/concomitant therapy.
