LBA68_PR: 5-year survival outcomes of the CheckMate 067 phase 3 trial of nivolumab plus ipilimumab (NIVO+IPI) combination therapy in advanced melanoma, by James Larkin

 

Abstract

Background

Results from CheckMate 067 have shown significant improvements in objective response, progression-free survival (PFS), and overall survival (OS) with NIVO+IPI and NIVO alone vs IPI in patients with advanced treatment-naive melanoma. Here we present 5-year outcomes from the study.

Methods

Eligible patients with previously untreated stage III or IV melanoma (N = 945) were randomly assigned 1:1:1 and stratified by programmed death ligand 1 (PD-L1) status, BRAF mutation status, and metastasis stage. Patients received NIVO 1 mg/kg + IPI 3 mg/kg for 4 doses Q3W followed by NIVO 3 mg/kg Q2W (n = 314), NIVO 3 mg/kg Q2W + placebo (n = 316), or IPI 3 mg/kg Q3W for 4 doses + placebo (n = 315) until progression or unacceptable toxicity. Co-primary endpoints were OS and PFS; the study was not powered to compare the NIVO-containing groups. Descriptive analyses were performed to evaluate efficacy between NIVO+IPI and NIVO, treatment-free status, and health-related quality of life (HRQoL).

Results

With a minimum follow-up of 60 months, the NIVO-containing arms continued to show improved OS, PFS, and response vs IPI (table). In addition, descriptive analyses showed longer OS with NIVO+IPI (median OS, > 60.0 mo [not reached]) than with NIVO alone (median OS, 36.9 mo), as well as a higher proportion of patients alive and treatment-free with the combination. No sustained deterioration of HRQoL (EQ-5D-3L utility index) was observed during treatment or following treatment discontinuation with NIVO or NIVO+IPI.Table:

NR, not reached.

a

Although a median was reported at the previous analysis, that estimate was immature and greater than the minimum study follow-up.

b

> 60.0 mo.

Conclusions

This 5-year analysis represents the longest phase III follow-up for checkpoint inhibitor combination therapy and demonstrates long-term survival with both NIVO-containing arms vs IPI. In descriptive analyses, NIVO+IPI was associated with improved survival and a higher likelihood of being alive and treatment-free compared with NIVO alone, both without loss of QoL.
