TraMel-WT: A Trial of Trametinib in Patients With Advanced Pretreated BRAFV600 Wild-type Melanoma

Summary

This phase 2 trial will investigate the efficacy and safety of trametinib and dabrafenib in patients with advanced BRAF V600 (v-Raf murine sarcoma viral oncogene homolog B) wild-type melanoma (stratified according to BRAF V600 wild-type/NRAS (neuroblastoma Ras viral oncogene homolog) mutant and BRAF V600 wild-type/NRAS wild-type melanoma patients) that have been pretreated and progressed following treatment with PD-1- (programmed cell death-1) and CTLA-4-blocking (cytotoxic T-lymphocyte-associated antigen 4) immune checkpoint inhibitors. The investigators hypothesize that treatment with trametinib will result in objective antitumor activity. In order to improve the tolerability and optimize the dose intensity of trametinib, a minimal dose of dabrafenib will be added to prevent and manage trametinib-related skin toxicity.
