About
The current study will compare pembrolizumab (MK-3475) plus maintenance olaparib, vs pembrolizumab plus maintenance pemetrexed for the treatment of nonsquamous NSCLC. The study's 2 primary hypotheses are: 1. Pembrolizumab plus maintenance olaparib is superior to pembrolizumab plus maintenance pemetrexed with respect to progression-free survival (PFS) per Response Evaluation Criteria in Solid Tumors (RECIST 1.1) by blinded independent clinical review (BICR) and 2. Pembrolizumab plus maintenance olaparib is superior to pembrolizumab plus maintenance pemetrexed with respect to overall survival (OS).
Full description
This study has 2 phases: an Induction Phase (4 Cycles) and a Maintenance Phase (Up to 31 cycles of pembrolizumab). In the Induction Phase, participants receive pembrolizumab plus pemetrexed plus platinum (carboplatin or cisplatin). In the Maintenance Phase, participants with a partial or complete disease response or with stable disease after completing four cycles of induction therapy and who meet eligibility criteria will be randomly assigned to receive pembrolizumab plus maintenance olaparib OR pembrolizumab plus maintenance pemetrexed. In the Maintenance Phase, participants receive pembrolizumab for up to 31 cycles plus maintenance olaparib OR maintenance pemetrexed until progressive disease (PD), intolerable toxicities, or physician decision.

Inclusion criteria
Have a histologically or cytologically confirmed diagnosis nonsquamous NSCLC.
Have stage IV nonsquamous NSCLC.
Have confirmation that epidermal growth factor receptor (EGFR), anaplastic lymphoma kinase (ALK), or Proto-oncogene tyrosine-protein kinase (ROS1)-directed therapy is not indicated.
Have measurable disease based on RECIST 1.1.
Have provided archival tumor tissue sample or newly obtained core or incisional biopsy of a tumor lesion not previously irradiated.
Note: Adequacy of biopsy specimen for the above analyses must be confirmed by the central laboratory before the participant can start the induction phase. Submission of another tumor specimen may be required prior to enrolling the participant, if adequate tumor tissue was not provided the first time.
Have a life expectancy of at least 3 months.
Have a performance status of 0 or 1 on the Eastern Cooperative Oncology Group (ECOG) Performance Status assessed within 7 days prior to the administration of study intervention.
Have not received prior systemic treatment for their advanced/metastatic NSCLC.
Have adequate organ function.
Male and female participants who are not pregnant and of childbearing potential must follow contraceptive guidance during the treatment period and for 180 days afterwards.
Male participants must refrain from donating sperm, and female participants must refrain from donating eggs to others or freeze/store for her own use during the treatment period and for 180 days afterwards.
