The combination of nivolumab (Opdivo) and ipilimumab (Yervoy) improved progression-free survival (PFS) compared with chemotherapy in treatment-naïve patients with high tumor mutation burden (TMB) non–small cell lung cancer (NSCLC).
When efficacy was compared between monotherapy and each of the combination arms in patients with PD-L1 expression ≥1%, median PFS was greatest in the nivolumab every 2 weeks, ipilimumab every 6 weeks interval cohort. Median PFS in this setting was 3.5 versus 10.4 versus 13.2 weeks, in patients receiving monotherapy, ipilimumab every 12 weeks, and ipilimumab every 6 weeks, respectively. Median 1-year OS rates showed a similar pattern; median OS was 69% with monotherapy, 91% with combined ipilimumab given every 6 weeks, and 83% with combined ipilimumab given every 12 weeks.
