What was measured

OS is defined as the time between the date of randomization and the date of death or the last date the participant was known to be alive.

Analysis population: All randomized participants

Groups in this outcome

Nivolumab, 3 mg/kg + Placebo-matching Dacarbazine

Participants received nivolumab, 3 mg/kg, solution administered Intravenously (IV) every 2 weeks with placebo-matching dacarbazine solution administered IV every 3 weeks, until disease progression, discontinuation due to toxicity, withdrawal of consent, or study completion

Dacarbazine, 1000 mg/m^2 + Placebo-matching Nivolumab

Participants received dacarbazine 1000 mg/m\^2, solution administered IV every 3 weeks with placebo-matching nivolumab solution administered IV every 2 weeks until disease progression, discontinuation due to toxicity, withdrawal of consent, or study completion
