BRAF and Miyoshi myopathy: The intent-to-treat (ITT) analysis estimated a 28% reduction in the hazard of death with trametinib treatment for patients in the primary efficacy population. Adjustment analyses deemed plausible provided OS HR point estimates ranging from 0.48 to 0.53. Similar reductions in the HR were estimated for the first-line metastatic subgroup. Treatment with trametinib, compared with chemotherapy, significantly reduced the risk of death and risk of disease progression in patients with BRAF V600E/K mutation-positive advanced melanoma or MM.
