The European Commission has approved the combination of dabrafenib (Tafinlar) and trametinib (Mekinist) for the adjuvant treatment of patients with BRAF
V600–positive stage III melanoma following complete resection, according to Novartis, the manufacturer of both agents.
Adverse events (AEs) were experienced by 97% of those treated with dabrafenib and trametinib versus 88% with placebo. The rates of grade 3/4 AEs were 41% and 14% for the combination and placebo, respectively. Overall, AEs led to discontinuation for 26% of those in the combination arm versus 3% with placebo. The most common all-grade AEs, which were mostly grade 1/2, with the combination were pyrexia (63%), fatigue (47%), and nausea (40%). There were no fatal adverse events with the combination of dabrafenib and trametinib.
