Summary
Brief summary
This is an efficacy and safety study of cosibelimab (CK-301) combined with
pemetrexed/platinum chemotherapy versus pemetrexed/platinum chemotherapy alone in
participants with advanced or metastatic non-squamous non-small cell lung cancer (NSCLC) who
have not previously received systemic therapy for advanced disease. Participants will be
randomly assigned in a 2:1 ratio to receive cosibelimab combined with pemetrexed/platinum
(Investigators choice of cisplatin or carboplatin), OR pemetrexed/platinum (Investigators
choice of cisplatin or carboplatin).

The primary hypothesis is that cosibelimab in combination with pemetrexed/platinum
chemotherapy prolongs Overall Survival (OS) compared to pemetrexed/platinum chemotherapy
alone.
