BRAF is a human gene that encodes a protein called B-Raf. The gene is also referred to as proto-oncogene B-Raf and v-Raf murine sarcoma viral oncogene homolog B , while the protein is more formally known as serine/threonine-protein kinase B-Raf .
Encorafenib, sold under the brand name Braftovi, is an anti-cancer medication used for the treatment of certain melanoma cancers. It is a small molecule BRAF inhibitor [4] that targets key enzymes in the MAPK signaling pathway. This pathway occurs in many different cancers including melanoma and colorectal cancers. [5]
V600E is a mutation of the BRAF gene in which valine (V) is substituted by glutamic acid (E) at amino acid 600. [1] [2] It is a driver mutation in a proportion of certain diagnoses, including melanoma, [3] [4] hairy cell leukemia, [5] [6] papillary thyroid carcinoma, [7] [8] colorectal cancer, [9] non-small-cell lung cancer, [10] [11] Langerhans cell histiocytosis, [12] Erdheim–Chester ...
BRAF inhibitors, such as vemurafenib and dabrafenib and a MEK inhibitor trametinib are the most effective, approved treatments for BRAF positive melanoma. [ 131 ] [ 124 ] Melanoma tumors can develop resistance during therapy which can make therapy no longer effective, but combining the use of BRAF and MEK inhibitors may create a fast and ...
The FDA approved binimetinib based primarily on evidence from one clinical trial (NCT01909453) of 383 patients with BRAF V600 mutation-positive melanoma that was advanced or could not be removed by surgery. [7] The trial was conducted at 162 sites in Europe, North America, and various countries around the world. [7]
Dabrafenib is indicated as a single agent for the treatment of people with unresectable or metastatic melanoma with BRAF V600E mutation. [2] Dabrafenib is indicated, in combination with trametinib, for BRAF V600E-positive unresectable or metastatic melanoma, metastatic non-small cell lung cancer, metastatic anaplastic thyroid cancer, and unresectable or metastatic solid tumors.
Cobimetinib or XL518, approved by US FDA in Nov 2015 for use in combination with vemurafenib (Zelboraf(R)), for treatment of advanced melanoma with a BRAF V600E or V600K mutation. Selumetinib , had a phase 2 clinical trial for non-small cell lung cancer (NSCLC) which demonstrated an improvement in PFS, [ 5 ] and is now in phase III development ...
