What Cotellic is

Cotellic is an anti-cancer medicine that contains the active substance cobimetinib.

What Cotellic is used for

Cotellic is used to treat adult patients with a type of skin cancer called melanoma, that has spread to other parts of the body or cannot be removed by surgery.

• It is used in combination with another anti-cancer medicine called vemurafenib.
• It can only be used in patients whose cancer has a change (mutation) in a protein called “BRAF”. Before starting treatment, your doctor will test for this mutation. This change may have led to the development of melanoma.

How Cotellic works

Cotellic targets a protein called “MEK” that is important in controlling cancer cell growth. When Cotellic is used in combination with vemurafenib (which targets the changed “BRAF” protein), it further slows down or stops the growth of your cancer.

Do not take Cotellic:

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

If you are not sure, talk to your doctor, pharmacist or nurse before taking Cotellic.

Warnings and precautions

Talk to your doctor, pharmacist or nurse before taking Cotellic if you have:

• Bleeding

Cotellic can cause severe bleeding, especially in your brain or stomach (see also “Severe bleeding” in Section 4). Tell your doctor straight away if you have any unusual bleeding or any of these symptoms: headaches, dizziness, feeling weak, blood in the stools or black stools and vomiting blood.

• Eye problems

Cotellic can cause eye problems (see also “Eye (vision) problems” in Section 4). Tell your doctor straight away if you get the following symptoms: blurred vision, distorted vision, partly missing vision, or any other changes to your sight during treatment. Your doctor should examine your eyes if you have any new or worsening problems with your sight while you are taking Cotellic.

• Heart problems

Cotellic can lower the amount of blood pumped by your heart (see also “Heart problems” in Section 4). Your doctor should do tests before and during your treatment with Cotellic to check how well your heart can pump blood. Tell your doctor straight away if it feels like your heart is pounding, racing or beating unevenly, or if you experience dizziness, lightheadedness, shortness of breath, tiredness, or swelling in the legs.

• Liver problems

Cotellic can increase the amount of some liver enzymes in your blood during treatment. Your doctor will do blood tests to check these amounts and monitor how well your liver is working.

• Muscle problems

Cotellic can cause increased levels of creatine phosphokinase, an enzyme that is found mainly in the muscle, heart, and brain. This can be a sign of muscle damage (rhabdomyolysis) (see also “Muscle problems” in Section 4). Your doctor will do blood tests to monitor for this. Tell your doctor straight away if you get any of these symptoms: muscle aches, muscle spasms, weakness, or dark- or red-coloured urine.

• Diarrhoea

Tell your doctor straight away if you get diarrhoea. Severe diarrhoea can cause loss of body fluid (dehydration). Follow your doctor’s instructions for what to do to help prevent or treat diarrhoea.

Children and adolescents

Cotellic is not recommended for children and adolescents. The effects of Cotellic in people younger than 18 years old are not known.
