---|---|---|---|---|---|---|---|---|
BRAF L485_P490del | Advanced Solid Tumor | predicted - resistant | Vemurafenib | Preclinical - Cell culture | Actionable | In a preclinical study, Zelboraf (vemurafenib) failed to inhibit phosphorylation of Mek and Erk in transformed cells expressing BRAF L485_P490del in culture (PMID: 26732095). | 26732095 | |
BRAF L485_P490del | Advanced Solid Tumor | predicted - sensitive | LY3009120 | Preclinical - Cell culture | Actionable | In a preclinical study, LY3009120 inhibited phosphorylation of Mek and Erk in transformed cells expressing BRAF L485_P490del in culture (PMID: 26732095). | 26732095 | |
BRAF L485_P490del | melanoma | predicted - sensitive | MEK inhibitor (Pan) MEK1 Inhibitor MEK2 Inhibitor | Dabrafenib + Trametinib | Case Reports/Case Series | Actionable | In a clinical case study, a patient with lymph node metastatic melanoma harboring BRAF L485_P490del and high CD274 (PD-L1) expression (TPS>=60%) experienced a partial response with regression of the target lesion after two cycles of second-line combination therapy with Tafinlar (dabrafenib) and Mekinist (trametinib), and at last follow up, demonstrated a sustained partial response and progression-free survival of at least 18 months (PMID: 36686670). | 36686670 |
