Combining BRAF Inhibition, Anti-PD-1 No Help in BRAF-Mutant Melanoma

Excerpt:

“Patients with BRAF-mutant melanoma obtained no survival benefit from combined treatment of anti-BRAF therapy and an immune checkpoint inhibitor, a retrospective analysis showed.

“Median progression-free survival (PFS) was 6.0 to 6.5 months in BRAF-inhibitor naive patients who received a PD-1/PD-L1 inhibitor alone or with a BRAF inhibitor. Patients with prior exposure to a BRAF inhibitor had a median PFS of 8.0 months with anti–PD-1 therapy and 4.5 months with combined treatment. Median overall survival was 10.5 to 12 months with a PD-1/PD-L1 inhibitor alone or in combination with a BRAF inhibitor, regardless of prior BRAF inhibitor exposure status.

“ ‘BRAF inhibitor-refractory patients derived no additional benefit with anti-PD therapy in combination with BRAF inhibition,’ Wen-Jen Hwu, MD, of MD Anderson Cancer Center in Houston, and colleagues concluded in a poster presentation at the 2016 ASCO Annual Meeting in Chicago. ‘Clinical findings are similar with either anti-PD alone or in combination with BRAF inhibition in terms of objective response rate (ORR), disease control rate (DCR), and overall survival (OS).’ ”
