FDA Approves Cotellic Combined with Zelboraf to Treat Advanced Melanoma

The FDA approved Cotellic (cobimetinib) to be used in combination with Zelboraf (vemurafenib) to treat advanced melanoma that has spread to other parts of the body or can’t be removed by surgery, and that has a certain type of abnormal gene (BRAF V600E or V600K mutation).Cotellic works by blocking the activity of an enzyme known as MEK, which is part of a larger signaling pathway. Abnormal activity of signaling pathways can lead to cancer. Cotellic prevents or slows cancer cell growth. Vemurafenib is a BRAF inhibitor that affects a different part of the same pathway and was approved in 2011 to treat patients with melanoma that has spread to other parts of the body or cannot be removed by surgery, whose tumors express a gene mutation called BRAF V600E, as detected by an FDA approved test. Health care providers should confirm the presence of BRAF V600 E or V600K mutation in their patients’ tumor specimens using one of the available FDA approved tests prior to starting treatment with Cotellic in combination with vemurafenib.Read more at Derm Wire.
