What Mektovi is and what it is used for
Mektovi is a cancer medicine that contains the active substance binimetinib. It is used in adults in combination with another medicine containing encorafenib to treat a type of skin cancer called melanoma when it has
- a specific change ( mutation ) in a gene responsible for producing a protein called BRAF, and
- spread to other parts of the body, or can not be removed by surgery.
Mutations in the BRAF gene can give rise to proteins that cause melanoma to grow. Mektovi targets another protein, “MEK”, which stimulates the growth of cancer cells. When Mektovi is used in combination with encorafenib (which targets the altered “BRAF” protein ), the combination slows the growth of cancer or stops it completely.
What you need to know before taking Mektovi
Before starting treatment, your doctor will check if you have a mutation in the BRAF gene.
Because Mektovi is to be used in combination with encorafenib, you should read both the encorafenib package leaflet and this leaflet carefully.
Do not take Mektovi
- if you are allergic to binimetinib or any of the other ingredients of this medicine (listed in section 6).

Tell your doctor if you have ever had a blood clot in the vein that carries blood away from the eye (retinal vein occlusion), as Mektovi is not recommended in such cases.
