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). |
