  Outcome Measures
  Show All Outcome Measures

1.  Primary:   Overall Survival (OS)   [ Time Frame: From date of randomization to date of death. For those without documentation of death, to the last date the participant was known to be alive, assessed to 17 months. ]

2.  Primary:   Overall Survival (OS) Rate   [ Time Frame: Randomization to 6 months and 12 months ]

3.  Secondary:   Progression-free Survival (PFS)   [ Time Frame: From date of randomization to date of disease progression or death, assessed to 17 months ]

4.  Secondary:   Progression-free Survival (PFS) Rate   [ Time Frame: Tumor assessments beginning at 9 weeks following randomization and continuing every 6 weeks for the first year, then every 12 weeks thereafter until disease progression or death, assessed to 17 months ]

5.  Secondary:   Objective Response Rate (ORR) Per Response Evaluation Criteria in Solid Tumors (RECIST)   [ Time Frame: Tumor assessments beginning at 9 weeks following randomization and continuing every 6 weeks for the first year, then every 12 weeks thereafter until disease progression or death, assessed to 17 months ]

6.  Secondary:   Overall Survival by Programmed Cell Death Ligand 1 (PD-L1) Expression Level   [ Time Frame: From date of randomization to date of disease progression or death, as assessed to 17 months ]

7.  Secondary:   Change From Baseline in Health-related Quality of Life (HRQoL) Scores   [ Time Frame: At baseline and every 6 weeks for 12 months and at follow-up visits 1 and 2, assessed up to 17 months ]

8.  Other Pre-specified:   Number of Participants Who Died and With Serious Adverse Events (SAEs), Drug-related SAEs, Adverse Events (AEs) Leading to Discontinuation, Drug-related AEs Leading to Discontinuation, and Drug-related AEs   [ Time Frame: Day of first dose to day of final dose + 30 days, assessed up go 17 months ]

  Limitations and Caveats
  Hide Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
An independent data monitoring committee (DMC) found that data from a DMC-requested database lock showed clear survival benefit with nivolumab and thus recommended unblinding the study and switching patients randomized to dacarbazine to nivolumab.
