Definition

An orally available inhibitor of wild-type and certain mutant forms of A-Raf, B-Raf and C-Raf protein kinases, with potential antineoplastic activity. Upon administration, tovorafenib inhibits Raf-mediated signal transduction pathways, which may lead to an inhibition of tumor cell growth. Raf protein kinases play a key role in the RAF/MEK/ERK signaling pathway, which is often deregulated in human cancers and plays a key role in tumor cell proliferation and survival.
