BRAF V600E | melanoma | sensitive | Dabrafenib + Trametinib | Phase II | Actionable | In a Phase II trial, BRAF V600E positive melanoma patients who progressed on treatment with BRAF inhibitors or the combination of Tafinlar (dabrafenib) and Mekinist (trametinib) were treated again with the combination of Tafinlar (dabrafenib) and Mekinist (trametinib) after 12 weeks off treatment, which resulted in a partial response in 35% (8/25) and stable disease in 40% (10/25) (PMID: 28268064). | 28268064 |
BRAF V600E | melanoma | sensitive | Dabrafenib + Trametinib | Preclinical | Actionable | In a preclinical study, Tafinlar (dabrafenib) in combination with Mekinist (trametinib) inhibited growth of melanoma cells harboring BRAF V600E in culture (PMID: 22389471). | 22389471 |
BRAF V600E | melanoma | sensitive | Dabrafenib + Trametinib | FDA approved - On Companion Diagnostic | Actionable | In a Phase III trial (COMBI-v) that supported FDA approval, the combination of Tafinlar (dabrafenib) and Mekinist (trametinib) resulted in an improved overall survival rate at 12 months (72% vs 65%, HR=0.69, p=0.005), median progression-free survival (11.4 vs 7.3 months, HR=0.56, p<0.001), and objective response rate (64% vs 51%, p<0.001) compared to Zelboraf (vemurafenib) in melanoma patients harboring BRAF V600E or V600K (PMID: 25399551; NCT01597908). | detail... detail... 25399551 |
