A Study to Compare the Efficacy of Nivolumab and Relatlimab Plus Chemotherapy with Pembrolizumab Plus Chemotherapy in Patients with Non-Squamous, Non-Small Cell Lung Cancer Stage IV/Recurrence with PD-L1 Expression ≥ 1 %

Critères de participation
- Participants must have a histologically confirmed non-small cell lung cancer (NSCLC) in stage IV or recurrence with non-squamous histology, for which no prior systemic cancer therapy has been administered as primary treatment for advanced or metastatic disease. - Participants must have measurable disease as assessed by computed tomography (CT) or magnetic resonance imaging (MRI) according to RECIST v1.1 criteria. - Participants must have an ECOG performance status (Eastern Cooperative Oncology Group) of ≤ 1 at screening, which must be confirmed prior to randomization. - Participants must have a life expectancy of at least 3 months at the time of randomization. - Participants must have a measurable PD-L1 value of ≥ 1% tumor cells (TC) in the tested immunohistochemistry test VENTANA PD-L1 (SP263) CDx Assay for the detection of PD-L1 expression. This test is performed by a central laboratory during the screening prior to randomization. (BASEC)

Critères d'exclusion
- Participants must not have untreated metastases in the central nervous system (CNS). - Participants must not have a concurrent malignancy requiring treatment. - Participants must not have an active autoimmune disease. - Participants must not have a history of interstitial lung disease or pneumonitis that requires oral or intravenous (IV) glucocorticoid treatment to support therapy. - Participants must not have a history of myocarditis. - Participants must not have received prior treatment with an anti-PD-1, anti-PD-L1, anti-PD-L2, or anti-CTLA-4 antibody or any other antibody or drug targeting T-cell co-stimulation or checkpoint pathways. - Additional inclusion and exclusion criteria defined in the study protocol apply. - Female participants must not be pregnant or breastfeeding. - Participants must not have leptomeningeal metastases (carcinomatous meningitis).
