Abstract

Background

In CheckMate 227 Part 1, first-line (1L) NIVO + IPI improved overall survival (OS) versus chemotherapy (chemo) in patients (pts) with advanced NSCLC and tumor PD-L1 ≥ 1% (a primary endpoint) and < 1% (prespecified descriptive analysis). With 3 years’ minimum follow-up, NIVO + IPI continued to provide durable responses and long-term efficacy benefits vs chemo.

Methods

CheckMate 227 Part 1 (NCT02477826) enrolled pts who were chemo-naive with stage IV / recurrent NSCLC. 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; those with PD-L1 < 1% (n = 550) were randomized 1:1:1 to NIVO + IPI, NIVO 360 mg Q3W + chemo, or chemo. Responses were assessed by blinded independent central review (BICR) using RECIST v1.1. An exploratory analysis assessed OS by best response as responders (complete or partial response [CR/PR]), or non-responders (stable disease [SD] or progressive disease [PD]) for NIVO + IPI or chemo. The impact of depth of tumor burden reduction (30–< 50%, 50–< 80%, and ≥ 80% from baseline) on OS was also investigated.

Results

After a minimum follow-up of 37.7 months (database lock, 28 Feb 2020), response rates (PD-L1 ≥ 1% and < 1%) were 33.4% with NIVO + IPI vs 28.0% with chemo. As expected, greater depth of response was associated with longer OS in both arms. The proportion of responders achieving ≥ 80% tumor burden reduction was 4x greater with NIVO + IPI vs chemo (10.8% vs 2.7%). Numerically longer median OS and higher 3-year OS rates were observed with NIVO + IPI vs chemo across tumor burden reduction categories (Table). Baseline characteristics and safety in responders will be presented.

Conclusions

In 1L advanced NSCLC, pts treated with NIVO + IPI had a higher chance of achieving deeper responses than those treated with chemo. Responders with greater tumor burden reduction had greater long-term OS benefit; this correlation was more pronounced with NIVO + IPI treatment than chemo.
