Uses for encorafenib

Encorafenib is used in combination with binimetinib to treat melanoma (skin cancer) that has spread or cannot be removed by surgery. It is only used if the melanoma cells have the BRAF V600E or V600K mutations. Your doctor will use a special test to look for these mutations. Encorafenib belongs to the group of medicines, called antineoplastics (cancer medicines).

Encorafenib is available only with your doctor's prescription.

Before using encorafenib

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For encorafenib, the following should be considered:

Proper use of encorafenib

Medicines used to treat cancer are very strong and can have many side effects. Before using encorafenib, make sure you understand all the risks and benefits. It is important for you to work closely with your doctor during your treatment.

Take encorafenib exactly as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. To do so may increase the chance of side effects.

Encorafenib usually comes with a Medication Guide. Read and follow the instructions carefully. Ask your doctor if you have any questions.

You may take encorafenib with or without food.

Do not eat grapefruit or drink grapefruit juice while you are using encorafenib.

Dosing

The dose of encorafenib will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of encorafenib. If your dose is different, do not change it unless your doctor tells you to do so.

The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.

  • For oral dosage form (capsules):
    • For melanoma:
      • Adults—450 milligrams (mg) (six 75 mg capsules) once a day. Your doctor may adjust your dose as needed and tolerated.
      • Children—Use and dose must be determined by your doctor.

Missed dose

If you miss a dose of encorafenib, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double doses.

If you missed a dose and it is 12 hours or less away, skip the missed dose and take the medicine at your regular dosing time. If your missed dose is more than 12 hours until the time you normally take a dose, take it as soon as you remember and go back to your regular dosing schedule.

If you vomit after taking a dose, do not take an extra dose. Take your next dose at your regular time.

Storage

Keep out of the reach of children.

Do not keep outdated medicine or medicine no longer needed.

Ask your healthcare professional how you should dispose of any medicine you do not use.

Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Keep from freezing.

Keep the medicine in its original container.

Precautions while using encorafenib

It is very important that your doctor check your progress at regular visits. This will allow your doctor to see if the medicine is working properly and to decide if you should continue to take it. Blood and urine tests will be needed to check for unwanted effects.

Using encorafenib while you are pregnant can harm your unborn baby. Birth control pills may not work as well to prevent pregnancy when used with encorafenib. Use another form of birth control (eg, condoms, diaphragms, contraceptive foams or jellies) along with your pills. Use an effective form of birth control during treatment with encorafenib and for at least 2 weeks after the last dose. If you think you have become pregnant while using the medicine, tell your doctor right away.

Encorafenib may cause fertility (ability to have children) problems in men. Talk to your doctor before using encorafenib if you plan to have children.

Encorafenib may increase your risk of having cutaneous squamous cell carcinoma (cuSCC) or other skin cancers. Check with your doctor right away if you develop any skin changes, including a new wart, change in size or color of a mole, or a skin sore or reddish bump that does not heal. Your doctor may want your skin be checked for new skin lesions before treatment, during treatment, and for up to 6 months after the last dose.

Encorafenib may cause hemorrhage (severe bleeding) in the stomach and bowel areas or in the brain. Call your doctor right away if you have any unusual or unexplained bleeding.

Check with your doctor right away if eye pain or a change in vision occurs during treatment. This could be a sign of a serious eye problem. Your doctor may want your eyes be checked by an ophthalmologist (eye doctor).

Contact your doctor right away if you have any changes to your heart rhythm. You might feel dizzy or faint, or you might have a fast, pounding, or uneven heartbeat. Make sure your doctor knows if you had a heart rhythm problem, such as QT prolongation.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
