In Vitro	In BRAF mutant SK-MEL-28 cells and KRAS mutant HCT116 cells, Trametinib (GSK1120212) DMSO solvate causes dose-dependent inhibition of ERK1/2 phosphorylation as well as dose-dependent growth inhibition. In both SK-MEL-28 and HCT116 cells, Trametinib DMSO solvate inhibits 50% p-ERK1/2 at nearly equivalent concentrations (0.8 and 1.8 nM, respectively). However, as the slopes of the curves reflect, in SK-MEL-28 cells, Trametinib DMSO solvate inhibits 90% p-ERK1/2 at a lower concentration (3.4 nM) than in HCT116 (33.3 nM). Furthermore, in both cell lines, 50% growth inhibition is only achieved at concentrations Trametinib DMSO solvate that produces near complete ERK1/2 inhibition (85 and 90%, respectively)[2].
In Vivo	Trametinib (GSK1120212) DMSO solvate is evaluated in vivo in an A549 (KRAS mutant cell line) xenograft model, orally dosing daily for 21 days (qd×21). In this study, near complete tumor growth inhibition is observed at 5.0 and 2.5 mg/kg [92 and 87% tumor growth inhibition (TGI), respectively] and to a lesser degree at 0.5 and 0.1 mg/kg (62 and 58% TGI). Although 5 mg/kg is the maximally tolerated dose (MTD) in this study, 3 mg/kg is the typically observed MTD. Dose-dependent antitumor activity with Trametinib DMSO solvate treatment has been similarly reported for several other KRAS and BRAF mutant tumor models[2].
Cell Assay	SK-MEL-28, and HCT116 cell lines are plated in triplicate 96 well microtitre plates at 5000 cells per well in culture media. Trametinib dissolved in DMSO or negative control (0.1% DMSO) are added the following day and one plate is harvested with 50 μL of CellTiter-Glo for a time 0 (T=0) measurement. Remaining duplicate cell plates are typically incubated for 72 h. Cells are then lysed with 50 μL CellTiter-Glo, and chemiluminescent signal is read on the Wallac EnVision 2100 plate reader. For measurement of cellular ERK1/2 phosphorylation, cells are seeded and treated with Trametinib, and lysed after 72 h in Tris lysis buffer supplemented with phosphatase and protease inhibitors. All samples are analyzed with a phospho-ERK1/2 ELISA. Plates are read on MSD.SI6000 and curves are analyzed using the XLfit curve-fitting tool. For comparison of the growth assay curve and pERK1/2 assay curve, data are background subtracted and normalized to the vehicle treatment control[2].
Animal Admin	Mice[2] A549 (human non-small cell lung carcinoma) model is established from cells grown in tissue culture and harvested aseptically using a trypsin digest. Female athymic mice (strain nu/nu) are injected subcutaneously with between 5×106 and 107 cells in 50% martigel. Tumors are allowed to establish for one to four weeks before use. Trametinib is administered orally at the indicated doses in 0.2 mL/20 g by weight. Tumors are measured twice weekly using Vernier calipers. Antitumor activity is defined as tumor growth inhibition representing the % volume differential in tumor growth between the treated and control tumors at the time vehicle tumors exceeded a volume of 1000 mm3.
