1. What is Mekinist and what is it used for

Mekinist is a medicine that contains the active substance trametinib. It is used alone or in combination with another medicine that contains dabrafenib to treat a type of skin cancer called melanoma that has spread to other parts of the body or cannot be removed by surgery.

Mekinist in combination with dabrafenib can also be used to prevent the return of melanoma after it has been removed by surgery.

Mekinist in combination with dabrafenib is also used to treat a type of lung cancer called non-small cell lung cancer (NSCLC).

Both types of cancer have a specific change (mutation) in a gene called BRAF at position V600. This mutation in the gene may have caused the development of cancer. This medicine works on the proteins produced by the mutated gene and slows down or stops the development of cancer.

2. What you need to know before you take Mekinist

Mekinist can only be used to treat melanomas and NSCLC that have a BRAF mutation. Therefore, before starting treatment, your doctor will check if you have this mutation.

If your doctor decides that you should take the combination treatment of Mekinist and dabrafenib, read the package leaflet of dabrafenib carefully, as well as this leaflet.

If you have any further questions on the use of this medicine, ask your doctor, pharmacist, or nurse.

Do not take Mekinist

• if you are allergic to trametinib or any of the other ingredients of this medicine (listed in section 6).

Talk to your doctor if you think this may apply to you.

Your doctor will advise you to have an eye check before starting treatment with Mekinist and during treatment. Your doctor may ask you to stop taking Mekinist or refer you to a specialist if you experience signs and symptoms in your vision, including:

• vision loss
• redness and irritation in the eyes
• seeing colored spots
• seeing a halo (blurred vision around objects)
• blurred vision

Skin Changes

Severe skin reactions have been reported in people taking Mekinist in combination with dabrafenib (frequency not known). If you notice any of the following:

• red patches on the torso that are circular or target-shaped, with central blisters. Skin peeling. Ulcers in the mouth, throat, nose, genitals, and eyes. These severe skin rashes can be preceded by fever and flu-like symptoms (Stevens-Johnson syndrome)
• widespread rash, fever, and swollen lymph nodes (DRESS or drug hypersensitivity syndrome)

• Stop taking the medicine and seek immediate medical attention.

Up to 3 in 100 people who take Mekinist in combination with dabrafenib may develop a different type of skin cancer called Squamous Cell Carcinoma (SCC). Others may develop a type of cancer called Basal Cell Carcinoma (BCC). Normally, these changes only affect the skin locally and can be removed with surgery, and treatment with Mekinist and dabrafenib can continue without interruption.

Some people who take Mekinist in combination with dabrafenib may also notice that they have new melanomas. These melanomas are usually removed by surgery, and treatment with Mekinist and dabrafenib can continue without interruption.

Your doctor will examine your skin before starting treatment with dabrafenib, then monthly while taking dabrafenib, and during the 6 months after treatment ends. The reason for these reviews is to look for new skin lesions that could be cancerous.

Your doctor will also examine your head, neck, mouth, and lymph nodes and will regularly perform a scan (Computed Tomography) of your chest and abdominal area. You may also have blood tests. These reviews serve to detect if you have developed other cancers, including squamous cell carcinoma. It is recommended that both at the beginning and at the end of treatment, a pelvic exam (in women) and anal exam be performed.

Mekinist, both as monotherapy and in combination with dabrafenib, may cause a rash or acne-like rash. Follow your doctor's instructions on what to do to prevent the appearance of a rash. If you experience any of these symptoms for the first time or if they worsen, inform your doctor or nurse as soon as possible.

Contact your doctor immediatelyif you experience severe skin rash with any of the following symptoms: blisters on the skin, blisters or sores in the mouth, skin peeling, fever, redness, or swelling in the face, blisters on the soles of the feet.

If you have a skin rash or if it worsens, inform your doctor or nurse as soon as possible.

Muscle Pain

Mekinist may cause muscle damage (rhabdomyolysis). Inform your doctor or nurse if you feel a new symptom or if any of the following symptoms worsen:

• muscle pain
• dark-colored urine due to kidney damage

Respiratory or Lung Problems

Mekinist may cause inflammation of the lungs (pneumonitis or interstitial lung disease). Inform your doctor or nurse if you have new symptoms or worsening of symptoms associated with breathing problems or lung problems, including:

• shortness of breath
• cough
• fatigue

Immune System Disorders

If you experience several symptoms simultaneously, such as fever, swollen lymph nodes, bruising, or skin rash, inform your doctor immediately. It may be a sign of a disease in which the immune system produces too many cells to fight infections, called histiocytes and lymphocytes, which can cause various symptoms (known as hemophagocytic lymphohistiocytosis); see section 2 (rare frequency).

Tumor Lysis Syndrome

Inform your doctor immediately if you experience the following symptoms: nausea, difficulty breathing, irregular heartbeats, muscle cramps, seizures, cloudy urine, decreased urine production, and fatigue. These may be signs of a condition resulting from the rapid breakdown of cancer cells that in some people can be life-threatening (tumor lysis syndrome or TLS), see section 2 (unknown frequency).
