LBA4_PR: Nivolumab (NIVO) + low-dose ipilimumab (IPI) vs platinum-doublet chemotherapy (chemo) as first-line (1L) treatment (tx) for advanced non-small cell lung cancer (NSCLC): CheckMate 227 Part 1 final, by Solange Peters

Abstract

Background

Part 1 of CheckMate 227 (NCT02477826), a phase III study in 1L NSCLC, has dual primary endpoints. The primary endpoint of progression-free survival (PFS) with NIVO + IPI vs chemo in patients (pts) with tumor mutational burden ≥ 10 mut/Mb was met, as reported previously. Here we present the primary endpoint of overall survival (OS) for NIVO + IPI vs chemo in pts with tumor PD-L1 expression ≥ 1%.

Methods

Pts were chemo-naive, with stage IV or recurrent NSCLC without EGFR or known ALK alterations, ECOG PS 0–1. Pts with PD-L1 ≥1% (n = 1189) were randomized 1:1:1 to NIVO 3 mg/kg Q2W + IPI 1 mg/kg Q6W, NIVO 240 mg Q2W, or histology-based chemo; pts with PD-L1 < 1% (n = 550) were randomized 1:1:1 to NIVO 3 mg/kg Q2W + IPI 1 mg/kg Q6W, NIVO 360 mg Q3W + chemo, or chemo. Pts were stratified by histology in both populations. Pts were treated until disease progression, unacceptable toxicity, or for 2 y of immunotherapy.

Results

Baseline characteristics were balanced across tx arms. Minimum follow-up for the primary endpoint was 29.3 mo. For pts with PD-L1 ≥ 1%, OS was significantly longer with NIVO + IPI vs chemo (HR 0.79, 97.72% CI: 0.65–0.96; P = 0.007); PFS, objective response rates, and duration of response favored NIVO + IPI vs chemo. OS benefit was also observed in pts with PD-L1 < 1% and all randomized pts (Table). Prespecified analyses showed enhanced efficacy with NIVO + IPI relative to NIVO in PD-L1 ≥ 1% and relative to NIVO + chemo in PD-L1 < 1%. Grade 3–4 tx-related adverse event rates in all randomized pts were 33% with NIVO + low-dose IPI, 19% with NIVO, and 36% with chemo.Table: LBA4_PR

c

Conclusions

CheckMate 227 met its primary endpoint of significantly improved OS with NIVO + IPI vs chemo in 1L advanced NSCLC with PD-L1 ≥ 1%. OS was also improved with NIVO + IPI in PD-L1 < 1% and in all randomized pts. Safety profile was consistent with previous reports in NSCLC. NIVO + IPI represents a new chemo-free tx option for pts in 1L advanced NSCLC.
