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).

Warnings and cautions

Talk to your doctor, pharmacist, or nurse before taking Mektovi and tell us about all your medical problems, especially if you have any of the following:

  • heart problems
  • bleeding problems or if you are taking any medicine that may cause bleeding
  • eye problems, such as glaucoma ( glaucoma ) or increased pressure in the eye
  • muscle problem
  • high blood pressure
  • blood clots
  • problems with the lungs or breathing
  • liver problem.

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.

Tell your doctor if you have had any other type of cancer other than melanoma, as binimethinib taken with encorafenib may make certain types of cancer worse.

Tell your doctor, pharmacist, or nurse immediately if you receive any of the following while taking this medicine:

  • Heart problems: Mektovi can make your heart work worse or aggravate pre-existing heart problems. Your doctor will check that your heart is functioning properly before and during treatment with this medicine. Talk to your doctor immediately if you experience any symptoms of heart problems such as feeling dizzy, tired or fainting, if you are short of breath, if you feel your heart pounding, rushing or beating irregularly, or if your legs are swollen.
  • Bleeding problems: Mectovia can cause serious bleeding problems. Tell your doctor immediately if you experience any symptoms of bleeding problems such as coughing up blood, having blood clots, vomiting blood or something resembling coffee grounds, red or black stools that look like tar, blood in the urine, abdominal pain or unusual vaginal bleeding. Also tell your doctor if you have a headache, feel dizzy or feel weak.
  • Eye problems: Mektovi can cause serious eye problems. Talk to your doctor immediately if you get blurred vision, vision loss or other vision changes (eg colored dots in the field of vision ) or halo (blurred contour around objects). Your doctor will examine your eyes for any vision problems while you are taking Mektovi.
  • Muscle problems: Mectovia can cause muscle breakdown ( rhabdomyolysis ). Your doctor will take blood samples to check for any muscle problems before and during treatment. As a precaution, you should drink plenty of fluids during treatment. Tell your doctor immediately if you experience muscle pain, cramps, stiffness, seizures or dark urine.
  • High blood pressure: Mektovi may increase blood pressure . Your doctor or nurse will check your blood pressure before and during treatment with Mektovi. Tell your doctor immediately if you have a severe headache, feel dizzy or dizzy or if your blood pressure is much higher than usual when measured with a blood pressure monitor at home.
  • Blood clots: Mektovi can cause blood clots in the arms or legs and if a clot passes to the lungs, it can be life-threatening. Tell your doctor immediately if you experience chest pain, sudden shortness of breath, difficulty breathing, pain in your legs with or without swelling, swollen arms and legs or if an arm or leg becomes cold and pale. If necessary, your doctor may interrupt your treatment or discontinue it altogether.
  • Lung or breathing problems: This medicine may cause lung or breathing problems such as inflammation of the lungs ( pneumonia or interstitial lung disease). Signs and symptoms of this can be: cough, shortness of breath or fatigue. If necessary, your doctor may interrupt your treatment or discontinue it altogether.
  • Skin changes: Mektovi, when taken with encorafenib, can cause other types of skin cancer such as squamous cell carcinoma of the skin. Your doctor will examine your skin before starting treatment, every two months during treatment and for up to 6 months after you stop taking these medicines, to make sure you have not developed any new skin cancer. Tell your doctor immediately if you notice any skin changes during or after treatment such as: a new wart , a wound or a reddish lump that is bleeding or not healing or if you have a birthmark that grows or changes color.Your doctor will also need to examine you for squamous cell carcinoma of your head, neck, mouth and lymph nodes and you will be examined with computed tomography at regular intervals. This is a precaution in the event that squamous cell carcinoma develops inside your body. Examination of the genitals (for women) and the anal area is also recommended before starting treatment and when it ends.
  • Liver problems: Mektovi can cause abnormal blood tests related to how your liver works (increased levels of liver enzymes). Your doctor will take blood samples to check your liver before and during treatment.
