Long-Term Survival Outcomes With First-Line Nivolumab Plus Ipilimumab–Based Treatment in Patients With Metastatic NSCLC and Tumor Programmed Death-Ligand 1 Lower Than 1%: A Pooled Analysis
Nivolumab plus ipilimumab–based treatment regimens have shown long-term, durable efficacy benefits in patients with metastatic NSCLC. Here we report clinical outcomes from a pooled analysis of patients with metastatic NSCLC and tumor programmed death-ligand 1 (PD-L1) lower than 1% treated with first-line nivolumab plus ipilimumab with or without two cycles of chemotherapy versus up to four cycles of chemotherapy in the randomized phase 3 CheckMate 227 and CheckMate 9LA studies.
