In vitro

Cobimetinib shows strong activity on cell growth inhibtion in a broad panel of tumor types, particularly in BRAF or KRAS mutant cancer cell lines. In combination with GDC-0941, GDC-0973 results in reduced viability, pathway inhibition, and increased apoptosis in 888MEL and A2058 cells. [1] Coadministration of GDC-0973 and vemurafenib significantly increases decreased levels of GLUT-1 on the cellular membrane across all BRAFV600E lines. [2]
