Consumer Medicine Information
What is in this leaflet
Please read this leaflet carefully before you start taking MEKTOVI
This leaflet answers some common questions about MEKTOVI. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have risks and benefits. Your doctor has weighed the risks of you taking MEKTOVI against the benefits they expect it will have for you.
If you have any concerns about taking this medicine, ask your doctor or pharmacist.
Keep this leaflet with the medicine. You may need to read it again.
What MEKTOVI is used for
MEKTOVI is an anti-cancer medicine containing the active ingredient binimetinib, which belongs to a group of medicines called ‘MEK inhibitors’.
MEKTOVI is used in combination with another medicine which contains the active ingredient, encorafenib (called BRAFTOVI®) to treat adult patients with a type of skin cancer called melanoma, which has spread to other parts of the body, or cannot be removed by surgery. The type of melanoma which MEKTOVI and BRAFTOVI are used to treat, has a particular change (mutation) in a gene called BRAF. This mutation in the BRAF gene may have produced proteins which caused the melanoma to develop.
Before you start treatment, your doctor will have tested you to confirm that you have this BRAF mutation.
MEKTOVI targets a protein called MEK which promotes cancer cell growth. When MEKTOVI is used in combination with BRAFTOVI (which targets the changed BRAF protein), it further slows down or stops the growth of your cancer.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.
This medicine is available only with a doctor's prescription.
BRAFTOVI is not recommended for children and adolescents aged under 18 years. The safety and efficacy of this medicine has not been established in this age group.
Before you take MEKTOVI
As MEKTOVI is to be used in combination with BRAFTOVI, you must also read the Consumer Medicine Information for BRAFTOVI.
