What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Overall survival (OS) among participants treated with first-line nivolumab
Time Frame: Up to 24 months
Time from start of first-line nivolumab to death from any cause among participants in Cohort 3. Associations between baseline demographic, clinical, and treatment characteristics and overall survival will be evaluated using Cox proportional hazards models.
Up to 24 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of participants who underwent Programmed cell Death Ligand 1 (PD-L1) testing prior to treatment initiation
Time Frame: Baseline
Associations between baseline demographic and clinical characteristics and likelihood of PD-L1 testing will be evaluated using logistic regression models.
Baseline
Number of participants by Programmed cell Death Ligand 1 (PD-L1) diagnostic antibody
Time Frame: Baseline
Baseline
Number of participants tested for Programmed cell Death Ligand1 (PD-L1) who meet Combined Positive Score (CPS) thresholds
Time Frame: Baseline
Baseline
Number of participants eligible for first-line nivolumab treatment
Time Frame: Baseline
Baseline
Number of eligible participants who received first-line nivolumab treatment
Time Frame: Up to 24 months
Associations between baseline demographic and clinical characteristics and receipt of first-line nivolumab will be evaluated using logistic regression models.
Up to 24 months
