NCIt definition : An orally available inhibitor of both monomer and dimer forms of activating mutations
of the serine/threonine-protein kinase BRAF (B-raf) protein, including V600 BRAF mutations,
non-V600 BRAF mutations, and RAF fusions, with potential antineoplastic activity.
Upon administration, brimarafenib targets and binds to both monomeric and dimeric
forms of activating BRAF mutations and fusions. This may result in the inhibition
of BRAF-mediated signaling and inhibit proliferation in tumor cells expressing BRAF
mutations and fusions. BRAF belongs to the RAF family of serine/threonine protein
kinases and plays a role in regulating the mitogen-activated protein kinase (MAPK)/
extracellular signal-regulated kinase (ERK) signaling pathway, which is often dysregulated
in human cancers and plays a key role in tumor cell proliferation and survival. BRAF
mutations and fusions have been identified in a number of solid tumors and are drivers
of cancer growth.;
