Summary
This is a multicenter, randomized, double-blind, placebo-controlled study of niraparib plus
pembrolizumab versus placebo plus pembrolizumab as maintenance therapy in participants with
advanced or metastatic non-small cell lung cancer (NSCLC) who have achieved stable disease
(SD), partial response (PR), or complete response (CR) following completion of standard of
care first-line platinum-based induction chemotherapy with pembrolizumab. The primary
hypotheses are: participants with confirmed diagnosis of NSCLC could benefit from niraparib
plus pembrolizumab versus placebo plus pembrolizumab with respect to Progression-free
survival (PFS) and Overall survival (OS).
