This is a randomized, double-blind, placebo controlled, multicenter, phase III study evaluating the efficacy and safety of ociperlimab in combination with tislelizumab and platinum-based doublet chemotherapy as first-line treatment for participants with locally advanced or metastatic NSCLC without actionable driver mutations.~Participants will receive study treatment every three weeks and will continue to receive it until RECIST 1.1 disease progression as determined by Investigator and confirmed by BIRC, unacceptable toxicity that precludes further treatment, treatment is discontinued at the discretion of the Investigator or participant, participant withdrawal of consent, pregnancy, lost to follow-up, or death.
The primary scientific question of interest is whether the addition of ociperlimab to platinum-based chemotherapy and tislelizumab improve progression-free survival (PFS) or overall survival (OS) compared to pembrolizumab and platinum-based chemotherapy as first-line therapy for participants with locally advanced or metastatic squamous or non-squamous NSCLC with PD-L1 expression of ≥1%.
