ZELBORAF VEMURAFENIB
Vemurafenib is a type of biological therapy drug called a cancer growth blocker. It stops cells producing a protein called BRAF, which makes some cancer cells grow and divide. About half of all melanoma skin cancers make too much BRAF due to a change in a gene. The gene is called the BRAF gene.
Vemurafenib is a treatment for people with advanced melanoma whose cancer cells have a change in the BRAF gene. You have a test to check for the gene change before starting treatment with vemurafenib.
Vemurafenib is also known by its brand name Zelboraf.
