Dabrafenib | Tafinlar | GSK2118436 | BRAF Inhibitor 25 | Tafinlar (dabrafenib) inhibits the activity of BRAF, including V600E, which results in the inhibition of tumor cell proliferation (PMID: 22735384). Tafinlar (dabrafenib) is FDA approved for BRAF V600E/K- positive unresectable or metastatic melanoma, and in combination with Mekinist (trametinib) for BRAF V600E/K-mutant melanoma, BRAF V600E-mutant non-small cell lung cancer, BRAF V600E-mutant anaplastic thyroid cancer, for adult and pediatric patients of 6 years or older with unresectable or metastatic solid tumors harboring BRAF V600E, and for pediatric patients of 1 year or older with low-grade glioma harboring BRAF V600E (FDA.gov). |
LXH 254 | LXH254|LXH-254|Naporafenib | BRAF Inhibitor 25 CRAF Inhibitor 12 | LXH 254 is a RAF inhibitor that selectively inhibits monomeric and dimerized BRAF and CRAF, which may lead to anti-tumor activity in RAF-mutant tumors and better tolerability (AACR Annual Meeting 2019, Abstract LB-114, PMID: 31059256). | |
Trametinib | Mekinist | GSK1120212 | MEK inhibitor (Pan) 26 MEK1 Inhibitor 26 MEK2 Inhibitor 24 | Mekinist (trametinib) inhibits MEK 1 and 2, which potentially leads to reduced tumor cell proliferation (PMID: 27956260). Mekinist (trametinib) is FDA approved for melanoma patients harboring BRAF V600E or BRAF V600K mutations, and in combination with Tafinlar (dabrafenib) for BRAF V600E/K-mutant melanoma, BRAF V600E- mutant non-small cell lung cancer, BRAF V600E-mutant anaplastic thyroid cancer, for adult and pediatric patients of 6 years or older with unresectable or metastatic solid tumors harboring BRAF V600E, and for pediatric patients of 1 year or older with low-grade glioma harboring BRAF V600E (FDA.gov). |

---|---|---|---|---|---|---|---|
BRAF V600E | melanoma | sensitive | Dabrafenib + LXH 254 + Trametinib | Preclinical - Cell culture | Actionable | In a preclinical study, combination treatment with LXH 254, Tafinlar (dabrafenib), and Mekinist (trametinib) in a melanoma cell line harboring BRAF V600E resulted in suppression of colony formation in culture (PMID: 33568355). | 33568355 |
BRAF V600E | colorectal cancer | sensitive | Dabrafenib + LXH 254 + Trametinib | Preclinical - Cell line xenograft | Actionable | In a preclinical study, combination treatment with LXH 254, Tafinlar (dabrafenib), and Mekinist (trametinib) in colorectal cancer cell lines harboring BRAF V600E resulted in suppression of colony formation in culture, and inhibition of tumor growth in a cell line xenograft model (PMID: 33568355). | 33568355 |
