Abstract 4998

Background

Simultaneous blockade of LAG-3 and PD-1 may synergistically restore T-cell activation and enhance antitumor immunity. In a phase 1/2a study (NCT01968109), BMS-986016 (anti–LAG-3) + nivolumab (anti–PD-1) showed promising antitumor activity in the mel prior IO cohort (Ascierto et al. J Clin Oncol. 2017;35(suppl) [abstr 9520]). Here, we describe updated efficacy and safety in a larger mel prior IO cohort in all-comer and biomarker-enriched populations.

Methods

Pts in the mel prior IO cohort received BMS-986016 80 mg + nivolumab 240 mg Q2W. Primary objectives were safety and objective response rate (ORR), disease control rate (DCR), and duration of response (DOR) per RECIST v1.1. Biomarker and efficacy correlations were also evaluated.

Results

As of June 15, 2017, 68 pts were treated; 57% had prior anti–CTLA-4 and 46% had ≥ 3 lines of prior therapy. In 61 efficacy-evaluable pts, ORR was 11.5% (1 complete, 6 partial [1 unconfirmed] responses); DCR was 49%. Median DOR was not reached (min [0.1+], max [39.3+]). ORR was ≥ 3.5-fold higher in pts with LAG-3 expression ≥ 1% vs 

Conclusions

This is the largest report of outcomes in pts treated with anti–LAG3 + anti–PD-1. BMS-986016 + nivolumab is well tolerated with a safety profile similar to nivolumab monotherapy and provides encouraging efficacy in a heavily pretreated, anti–PD-1/PD-L1 progressed melanoma population. Enhanced responses correlated with LAG-3 expression, irrespective of PD-L1 expression.
