Cobimetinib (Cotellic)
General information
Class/mechanism: Tyrosine kinase inhibitor, MEK1 (mitogen-activated extracellular signal regulated kinase 1) and MEK2 inhibitor. Cobimetinib inhibits the mitogen-activated protein kinase (MAPK)/extracellular signal-related kinase (ERK) pathway by inhibiting MEK1 and MEK2. Cancers with BRAF V600E and K mutations have constitutive activation of the BRAF pathway, which includes MEK1 and MEK2. Inhibiting MEK1 and MEK2 results in inhibition of ERK and cellular proliferation.[1][2]
Route: PO
Extravasation: n/a
