---|---|---|---|---|---|---|---|---|
BRAF G464E | Advanced Solid Tumor | resistant | Vemurafenib | Preclinical - Cell culture | Actionable | In a preclinical study, Zelboraf (vemurafenib) did not inhibit MEK and ERK activation in transformed cells over expressing the constitutively dimerized BRAF G464E (PMID: 26343582). | 26343582 | |
BRAF G464E | sarcomatoid carcinoma | no benefit | MEK inhibitor (Pan) MEK1 Inhibitor MEK2 Inhibitor | Trametinib | Case Reports/Case Series | Actionable | In a Phase II trial (NCI-MATCH), Mekinist (trametinib) treatment did not demonstrate clinical activity in patients with advanced solid tumors or lymphoma harboring BRAF fusion or non-V600 mutations, resulted in stable disease with a progression-free survival of 6.9 months in a patient with spindle cell carcinoma harboring a BRAF G464E (PMID: 31924734; NCT02465060). | 31924734 |
BRAF G464E | melanoma | predicted - sensitive | PHI-501 | Preclinical - Cell line xenograft | Actionable | In a preclinical study, PHI-501 inhibited growth and migration and induced apoptosis in a melanoma cell line harboring BRAF G464E in culture and inhibited tumor growth in a cell line xenograft model (Cancer Res (2023) 83 (7_Supplement): 1627). | detail... | |
BRAF G464E | melanoma | sensitive | SIJ777 | Preclinical - Cell culture | Actionable | In a preclinical study, SIJ777 inhibited Mek, Erk, and Akt phosphorylation, proliferation, migration, invasion, and colony formation, and induced apoptosis in a melanoma cell line harboring BRAF G464E in culture (PMID: 33917428). | 33917428 |
