Roche announced that the EU Committee for Medicinal Products for Human Use (CHMP) has adopted a positive opinion for Cotellic (cobimetinib), when used in combination with Zelboraf® (vemurafenib), for the treatment of BRAF V600 mutation-positive unresectable or metastatic melanoma. Approximately 50% of melanoma skin cancers are BRAF-positive, and more than 55,000 people worldwide die every year from melanoma.
Melanoma is less common, but more aggressive and deadlier than other forms of skin cancer. A V600 mutation of the BRAF protein occurs in approximately half of melanomas, and should therefore be tested to identify the best treatment option. When melanoma is diagnosed early, it is generally a curable disease but most people with advanced melanoma have a poor prognosis. More than 232,000 people worldwide are currently diagnosed with melanoma each year. In recent years, there have been significant advances in treatment for metastatic melanoma, and people with the disease have more options. However, it continues to be a serious health issue with a high unmet need and a steadily increasing incidence over the past 30 years.
Zelboraf was the first approved treatment for patients with unresectable or metastatic melanoma with BRAF V600 mutation as detected by a validated test, such as Roche’s cobas 4800 BRAF Mutation Test. Zelboraf is not indicated for use in patients with wild-type BRAF melanoma. Cotellic (cobimetinib) is designed to selectively block the activity of MEK, one of a series of proteins inside cells that make up the MAPK signaling pathway that helps regulate cell division and survival.
Cotellic is also being investigated in combination with several investigational medicines, including immunotherapy, in several tumour types such as non-small cell lung cancer and colorectal cancer. Cotellic was discovered by Exelixis Inc. and is being developed by Roche in collaboration with Exelixis.
