Description

Trametinib is a reversible and specific inhibitor of mitogen-activated protein kinase kinases MEK1 and MEK2 which are involved in a RAS/RAF/MEK/ERK signaling pathway and control cell growth, survival, and differentiation. By inhibiting MEK1 and MEK2 trametinib blocks dual phosphorylation of ERK1/2 and stops cell cycling. In addition, trametinib blocks BRAF pathway in the cells with BRAF V600E mutations. Trametinib (as a single agent and in combination with dabrafenib) is approved for the treatment of unresectable or metastatic melanoma with BRAF V600E or V600K mutations.

Sample Use Guides

In Vivo Use Guide
Confirm the presence of BRAF V600E or V600K mutation in tumor specimens prior to initiation of treatment with MEKINIST. The recommended dosage regimens of MEKINIST are 2 mg orally once daily as a single agent or in combination with dabrafenib 150 mg orally twice daily.Take MEKINIST at least 1 hour before or at least 2 hours after a meal.
Route of Administration: Oral
In Vitro Use Guide
A375 and SK-MEL-28 untransfected or transfected with Mcl-1 plasmid were treated with 2 nM trametinib for 72 hours. The cell survival was evaluated by sulforhodamine B assay.
