COTELLIC®Indication
COTELLIC (cobimetinib) is a prescription medicine that is used with ZELBORAF (vemurafenib), to treat a type of skin cancer called melanoma that has spread to other parts of the body or cannot be removed by surgery, and that has a certain type of abnormal “BRAF” gene.
A patient’s healthcare provider will perform a test for the BRAF gene to make sure that COTELLIC is right for them. It is not known if COTELLIC is safe and effective in children under 18 years of age.
COTELLIC Important Safety Information
Patients should avoid sunlight during treatment with COTELLIC. COTELLIC can make their skin sensitive to sunlight. They may burn more easily and get severe sunburns. To help protect against sunburn, they should wear clothes that protect their skin, including their head, face, hands, arms, and legs. They should use lip balm and a broad-spectrum sunscreen with SPF 30 or higher.
COTELLIC may cause serious side effects, including risk of new skin cancers, bleeding problems, heart problems, severe rash, eye problems, liver problems, muscle problems (rhabdomyolysis), and photosensitivity. Patients should tell their doctor if they are pregnant or plan to become pregnant, as COTELLIC and ZELBORAF can harm an unborn baby. Patients who take COTELLIC should use effective methods of birth control during treatment, for 2 weeks after stopping COTELLIC, and for at least 2 months after stopping ZELBORAF. Do not breastfeed during treatment with COTELLIC and for 2 weeks after the final dose. Patients along with their healthcare provider should decide if they will take ZELBORAF or breastfeed. Patients should not do both.
Patients should tell their healthcare provider about all the medicines they take. Some types of medicines will affect the blood levels of COTELLIC.
Common side effects of COTELLIC include diarrhea, sunburn or sun sensitivity, nausea, fever, and vomiting. COTELLIC can also cause changes in blood test results.
Patients should tell their healthcare provider if they have any side effect that bothers them or that does not go away. These are not all the possible side effects of COTELLIC. For more information about side effects, patients should ask their healthcare provider or pharmacist.
Patients should call their doctor for medical advice about side effects.
They may report side effects to
