How does this medication work? What will it do for me?

Encorafenib belongs to the class of medications called antineoplastics. Specifically, it is a protein kinase inhibitor. This medication is used in combination with binimetinib, to treat melanoma (skin cancer) that cannot be surgically removed or has metastasized (spread to other parts of the body). Encorafenib is also used in combination with cetuximab, to treat metastatic colorectal cancer (mCRC).

This medication works by interfering with the communication between cells that causes uncontrolled tumour growth.

Encorafenib is not appropriate for all types of melanoma or colorectal cancer. It will only interfere with the growth of cancer cells that have a particular genetic mutation, called BRAF V600. Your doctor will check for this mutation before prescribing encorafenib.

Are there any other precautions or warnings for this medication?

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.

Birth control: Encorafenib may cause harm to the developing baby if it is taken during pregnancy. It is important that people who may become pregnant use effective birth control while taking this medication and for at least 2 weeks after the last dose. Birth control should include a barrier method, such as condoms, as hormonal birth control measures are not effective when used with encorafenib.

People whose partners are or may become pregnant should use effective barrier birth control while taking encorafenib and for at a least one week after the last dose.

Bleeding: This medication may cause a reduced number of platelets in the blood, which can make it difficult to stop cuts from bleeding. If you notice any signs of bleeding, such as frequent nosebleeds, unexplained bruising, or black and tarry stools, notify your doctor as soon as possible. Your doctor will order routine blood tests to make sure potential problems are caught early.

Blood clots: This medication may increase the chance of blood clot formation, causing reduction of blood flow to organs or the extremities. If you have a history of clotting you may be at increased risk of experiencing blood clot-related problems such as heart attack, stroke, or clots in the deep veins of your leg. Discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

If you experience symptoms such as sharp pain and swelling in the leg, difficulty breathing, chest pain, blurred vision or difficulty speaking, contact your doctor immediately.

Diabetes: Encorafenib may cause an increase in blood sugar levels (may cause a loss of blood glucose control) and glucose tolerance may change. People with diabetes may find it necessary to monitor their blood sugar more frequently while using this medication.

If you have diabetes or are at risk for developing diabetes, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Drowsiness/reduced alertness: Encorafenib may cause fatigue or vision problems, affecting your ability to drive or operate machinery. Avoid driving, operating machinery, or performing other potentially hazardous tasks until you have determined how you are affected by this medication.

Eye inflammation: This medication may cause eye inflammation. If you experience eye pain, changes in your vision, or eye pain when you are exposed to light, contact your doctor as soon as possible.

Heart rhythm: Encorafenib can cause changes to the normal rhythm of the heart, including an irregular heartbeat called QT prolongation. QT prolongation is a serious life-threatening condition that can cause fainting, seizures, and sudden death. If you are at risk for heart rhythm problems (e.g., people with heart failure, angina, low potassium or magnesium levels), discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Liver function: Liver disease or reduced liver function may cause this medication to build up in the body, causing side effects. If you have liver problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Encorafenib has been reported to cause decreased liver function. If you experience symptoms of liver problems such as fatigue, feeling unwell, loss of appetite, nausea, yellowing of the skin or whites of the eyes, dark urine, pale stools, abdominal pain or swelling, and itchy skin, contact your doctor immediately.

Your doctor may want to test your liver function regularly with blood tests while you are taking this medication. This often allows reduced liver function to be identified before it becomes too severe.

Other cancers: New cancerous lesions on the skin, such as squamous cell cancer or new melanomas can occur while you are taking encorafenib. It is important to have your skin examined before starting this medication, every 2 months while you are taking this medication, and until 6 months after stopping the medication. Signs of squamous cell cancer include sores, warts, or bumps that bleed or do not heal. Signs of melanoma include moles with an irregular shape, border, or colour that are changing shape or are growing. If you notice any of these signs, contact your doctor as soon as possible.

Pregnancy: Encorafenib can cause harm to the developing baby if it is taken during pregnancy. This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.

Breast-feeding: It is not known if encorafenib passes into breast milk. If you are breast-feeding and taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.

Children: The safety and effectiveness of using this medication have not been established for children.
