Abstract 4311


Combined inhibition of PD-1 and CTLA-4 with NIVO and IPI has demonstrated increased antitumor activity across several tumor types at various doses. In melanoma (MEL), NIVO 1 mg/kg plus IPI 3 mg/kg (NIVO1+IPI3) is the approved dose based on the CheckMate 067 trial, in which NIVO1+IPI3 and NIVO 3 mg/kg showed a higher objective response rate (ORR), longer progression-free survival (PFS), and improved overall survival (OS) vs IPI alone in patients (pts) with treatment-naive advanced MEL. CheckMate 511 was conducted to determine if NIVO 3 mg/kg plus IPI 1 mg/kg (NIVO3+IPI1) improves the safety profile of the combination.


Eligible pts were ≥18 years of age with unresectable stage III or IV MEL, an ECOG performance status of 0 or 1, no prior systemic therapy, and measurable disease by RECIST v1.1. Pts (N=360) were randomized 1:1 to NIVO3+IPI1 or NIVO1+IPI3 Q3W x 4; after combination therapy, pts in both groups received NIVO at 480 mg Q4W until progression or unacceptable toxicity. The primary objective was to compare the incidence of treatment-related grade 3-5 adverse events (AEs) between groups. Secondary objectives included descriptive analyses of efficacy endpoints, including ORR, PFS, and OS.


At a minimum follow-up of ~12 months, the incidence of treatment-related grade 3-5 AEs among treated pts was significantly lower with NIVO3+IPI1 vs NIVO1+IPI3 (Table). One treatment-related grade 5 AE was reported in the NIVO3+IPI1 group and none in the NIVO1+IPI3 group. While ORR numerically favored NIVO1+IPI3, there were no significant differences in ORR, PFS or OS (Table).

CheckMate 511 met its primary endpoint, demonstrating a significantly lower incidence of treatment-related grade 3-5 AEs with NIVO3+IPI1 compared with NIVO1+IPI3 in MEL. Similar efficacy outcomes were observed between the two groups; however, longer follow-up may help to better evaluate outcomes.
