Brief Summary
This is a Phase 1b/2 study evaluating the anti-PD1 antibodya protein made by the immune system to fight against harmful substances (antigens), such as bacteria or viruses, cemiplimab, in combination with either S095018 (anti-TIM3 antibody), S095024 (anti-CD73 antibody), or S095029 (anti-NKG2A antibody) in adult participants with previously untreated advancedat a late stage, far along/metastatic non-small cell lung cancer (NSCLC) with high PD-L1 expression. The study includes two parts: part A, the combination-therapy safety lead-in phase to determine the recommended dose for expansion (RDE) for S095018, S095024, and S095029 in combination with cemiplimab and part B, the randomized dose expansion phase to assess the efficacy of S095018, S095024, or S095029 in combination with cemiplimab. Study treatment will be administered for a maximum of 108 weeks, or until confirmed disease progression per iRECIST and/ or until meeting other treatment discontinuation criteria.
