Additional Information:

Trametinib is a highly potent (IC50 uMEK1 = 0.7 nM, pp-MEK1 = 14.9 nM) (1) and is a selective MEK inhibitor displaying selective inhibition of proliferation in various BRAF mutant cancer cell lines (IC50 ACHN = 9.8 nM; IC50 HT-29 = 0.57 nM) (2). This compound is approved for use against unresectable or metastatic BRAF-mutant melanoma alone or in combination with Dabrafenib. Trametinib can limit outgrowth of tumors without directly inhibiting tumor cell proliferation via abrogation of cytokine-driven expansion of monocytic myeloid-derived suppressor cells (mMDSC) through a mechanism involving CD8+ T cells.3,4 Trametinib also displays potent anti-arthritic effects.5
