The U.S. Food and Drug Administration (FDA) has approved Opdivo (nivolumab) injection, for intravenous use, for the treatment of patients with metastatic non-small cell lung cancer (NSCLC) with progression on or after platinum-based chemotherapy. Patients with EGFR mutation or ALK translocation should have disease progression on appropriate targeted therapy prior to receiving Opdivo. In a Phase 3 trial, CheckMate -057, Opdivo demonstrated superior overall survival (OS) in previously treated metastatic non-squamous NSCLC compared to chemotherapy, with a 27% reduction in the risk of death (hazard ratio: 0.73 [95% CI: 0.60, 0.89; p=0.0015]), based on a prespecified interim analysis.1 The median OS was 12.2 months in the Opdivo arm (95% CI: 9.7, 15.0) and 9.4 months in the docetaxel arm (95% CI: 8.0, 10.7). This approval expands Opdivo’s indication for previously treated metastatic squamous NSCLC to include the non-squamous patient population. Squamous and non-squamous NSCLC together represent approximately 85% to 90% of lung cancer cases.
