P1.01-02 - Long-Term Outcomes with First-Line Nivolumab Plus Ipilimumab in Advanced NSCLC: 3-Year Follow-Up from CheckMate 012 (ID 12380)

- Abstract
Background
CheckMate 012 (NCT01454102) is a phase 1 study evaluating several nivolumab monotherapy/combination regimens as first-line treatment for advanced non-small cell lung cancer (NSCLC). CheckMate 012 was the first study to suggest the benefit of nivolumab plus ipilimumab in NSCLC. In the phase 3 study CheckMate 227, nivolumab plus ipilimumab recently demonstrated significantly improved progression-free survival (PFS) as well as more frequent, deeper, and more durable responses versus chemotherapy in patients with chemotherapy-naive advanced NSCLC and high tumor mutational burden (TMB). Here, we provide 2-year follow-up results for nivolumab plus ipilimumab from CheckMate 012. Three-year results, the longest follow-up to date for an immuno-oncology combination in NSCLC, will be presented.

Eligible patients had recurrent stage IIIb or stage IV chemotherapy-naive NSCLC and Eastern Cooperative Oncology Group performance status 0–1. Patients received nivolumab 3 mg/kg every 2 weeks plus ipilimumab 1 mg/kg every 12 weeks (n=38) or every 6 weeks (n=39) until disease progression, unacceptable toxicity, or consent withdrawal; pooled results of these two cohorts are presented. Endpoints included safety/tolerability (primary); objective response rate and PFS (secondary); and overall survival (OS), chemotherapy-free survival (CFS), and efficacy by TMB status (exploratory).

With 2 years of follow-up, no new safety signals were observed. Thirty-three of 77 patients (43%) achieved objective responses, including six investigator-assessed complete responses (8%), three of which were complete pathological responses. Responses were durable (median duration of response, not reached; range, 1.4+ to 27.9+ months). The 2-year PFS rate was 29%. At the time of database lock, 32 of 34 patients (94%) with OS ≥2 years were alive, with four (12%) remaining on treatment and progression-free; 14 (41%) were off treatment and progression-free without subsequent therapy. Three-year follow-up results to be presented include OS, PFS, and select data on CFS, efficacy by TMB status, and characteristics of long-term survivors.

With long-term follow-up, nivolumab plus ipilimumab continued to demonstrate durable clinical benefit and a consistent safety profile as first-line treatment for patients with advanced NSCLC.
