Four out of 6 OR are observed in pts with MAPK-pathway activating mutations (3 class II BRAF and 1 GNAQ mutation)....In this two-stage phase 2 trial, T plus LD-D was found to have promising antitumor activity and acceptable toxicity in pts with advanced pretreated BRAFV600/NRASQ61R/K/L wt melanoma, especially in the presence of identifiable somatic MAPK-pathway activating mutations.
