A randomized phase II trial has found that consolidation therapy with nivolumab (Opdivo) plus ipilimumab (Yervoy) after chemoradiotherapy did not lead to better survival outcomes for patients with small cell lung cancer (SCLC). The study enrolled 222 patients with stage I-IIIB histologically or cytologically confirmed limited-disease SCLC, and adequate hematologic, renal, lung, and pulmonary function. The combination regimen yielded no improvement in overall survival, and grade 3 adverse events were approximately 2.5 times more common in the dual therapy group.
