Merck announced that the pivotal Phase 3 KEYNOTE-189 trial investigating KEYTRUDA® (pembrolizumab), Merck’s anti-PD-1 therapy, in combination with pemetrexed (Alimta®) and cisplatin or carboplatin, for the first-line treatment of patients with metastatic non-squamous non-small cell lung cancer (NSCLC), met its dual primary endpoints of overall survival (OS) and progression-free survival (PFS). Based on an interim analysis conducted by the independent Data Monitoring Committee, treatment with KEYTRUDA in combination with pemetrexed plus platinum chemotherapy resulted in significantly longer OS and PFS than pemetrexed plus platinum chemotherapy alone. The safety profile of KEYTRUDA in this combination was consistent with that previously observed. Results from KEYNOTE-189 will be presented at an upcoming medical meeting and submitted to regulatory authorities.
