What was measured

OS was defined as the time between the date of randomization and the date of death. For participants without documentation of death, OS was censored on the last date the participant was known to be alive.

Analysis population: All randomized participants

Groups in this outcome

Nivolumab

Nivolumab monotherapy 3 mg/kg intravenous (IV) once every 2 weeks (Q2W) until disease progression or unacceptable toxicity

Nivolumab + Ipilimumab

Nivolumab 1 mg/kg IV combined with Ipilimumab 3 mg/kg IV once every 3 weeks (Q3W) for 4 doses followed by nivolumab 3 mg/kg IV Q2W until disease progression or unacceptable toxicity

Ipilimumab

Ipilimumab monotherapy 3 mg/kg IV Q3W for a total of 4 doses
