Abstract 3982


NIVO+IPI and NIVO significantly improved PFS and OS vs. IPI alone in the CheckMate 067 study. Descriptively, NIVO+IPI showed longer OS than NIVO (hazard ratio: 0.88), with 2-year OS rates of 64% and 59%, respectively. Post-hoc analyses by region were performed to evaluate potential differences between patients (pts) treated in the EU and those treated in the USA.


Baseline patient characteristics, safety and efficacy were evaluated in the two highest enrolling regions (EU, 55% and USA, 22%) using data from the CheckMate 067 study. Minimum follow-up of the pts was 28 months.


EU pts were more likely to have M1c disease than USA pts (60% vs 53%), and more likely to have BRAF wild-type (WT) tumors (69% vs 59%). In a multivariate analysis, which adjusted for baseline factors, the only significant interaction between NIVO+IPI and NIVO was by region. Adjusted hazard ratios (HRs) for OS in the NIVO+IPI vs NIVO groups were 0.90 (0.66–1.23) for the EU and 0.53 (0.29–0.98) for the USA. Across all arms, 2-year OS rates were lower in the EU vs USA pts, particularly for pts with BRAF WT tumors (Table). In pts with BRAF mutant tumors, similar OS outcomes were observed between regions. Treatment exposure, safety, management of adverse events, and use of subsequent therapies did not differ substantially between the two regions. Objective response rates and progression-free survival were also similar between the two regions.Table:

Differences in OS between the EU and the USA appear to be largely due to poorer survival outcomes in EU pts with BRAF WT tumors, which likely impacted OS differences between NIVO+IPI and NIVO in the overall population. Additional analyses by region, the first report of 3-year OS, as well as analyses by tumor mutational burden will be presented. Acknowledgement: J. Larkin and J.D.
