OverviewTOP

Trametinib is used alone or in combination with dabrafenib to treat melanoma (skin cancer) that has spread or that cannot be removed by surgery and non-small cell lung cancer (NSCLC) that has spread. It is only used if the melanoma cells have the BRAF V600E or V600K mutations and if the NSCLC cells have the BRAF V600E mutation. Your doctor will use a special test to look for these mutations. Trametinib belongs to the group of medicines, called antineoplastics (cancer medicines).
