Overview

Generic Name(s):
vemurafenib
Trade Name(s):
Zelboraf
NCI Definition [1]:
An orally bioavailable, ATP-competitive, small-molecule inhibitor of BRAF(V600E) kinase with potential antineoplastic activity. Vemurafenib selectively binds to the ATP-binding site of BRAF(V600E) kinase and inhibits its activity, which may result in an inhibition of an over-activated MAPK signaling pathway downstream in BRAF(V600E) kinase-expressing tumor cells and a reduction in tumor cell proliferation. Approximately 90% of BRAF gene mutations involve a valine-to-glutamic acid mutation at residue 600 (V600E); the oncogene protein product, BRAF(V600E) kinase, exhibits a markedly elevated activity that over-activates the MAPK signaling pathway. The BRAF(V600E) gene mutation has been found to occur in approximately 60% of melanomas, and in about 8% of all solid tumors, including melanoma, colorectal, thyroid and other cancers.

Biomarker-Directed Therapies

Vemurafenib has been investigated in 34 clinical trials, of which 27 are open and 7 are closed. Of the trials investigating vemurafenib, 1 is early phase 1 (1 open), 6 are phase 1 (4 open), 3 are phase 1/phase 2 (3 open), and 24 are phase 2 (19 open).

BRAF Codon 600 Missense, BRAF V600E, and BRAF V600K are the most frequent biomarker inclusion criteria for vemurafenib clinical trials.

Melanoma, malignant solid tumor, and multiple myeloma are the most common diseases being investigated in vemurafenib clinical trials [2].
