An Open-Label, Randomized Phase 3 Trial of Nivolumab, or Nivolumab Plus Ipilimumab, or Nivolumab Plus Platinum Doublet Chemotherapy Versus Platinum Doublet Chemotherapy in Subjects With Chemotherapy-Naïve Stage IV or Recurrent Non-Small Cell Lung Cancer (NSCLC)

Progression-Free Survival Per BICR

时间窗: From randomization untill disease progression or death, whichever occurs first (up to approximately 481 weeks)

Progression-Free Survival then (PFS) is defined as the time between the date of randomization and the date of first documented disease progression, based on BICR assessments (per RECIST v1.1), or death due to any cause, whichever occurs first based on Kaplan-Meier estimates. Progressive Disease (PD): At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum during the study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm.

Overall Survival

时间窗: From randomization untill death or last follow up whichever occurs first (up to approximately 481 weeks)

OS for all randomized participants is the time between randomization date and the date of death from any cause.
