| BRAF R239Q BRAF L597S | melanoma | sensitive | Dabrafenib + Trametinib | Preclinical - Pdx & cell culture | Actionable | In a preclinical study, the addition of Tafinlar (dabrafenib) to treatment with Mekinist (trametinib) resulted in increased growth inhibition in a patient-derived melanoma cell line harboring BRAF L597S, as well as well as BRAF R239Q, in culture, and resulted in tumor shrinkage in 100% (13/13) of subcutaneous tumors, and decreased growth of intracranial tumors in a patient-derived xenograft (PDX) model (PMID: 29903896). | 29903896 |
