About Brigatinib (Alunbrig®)

A kinase is an enzyme that helps a cell grow. There are different types of kinases. Each type affects a different phase of cell growth. Kinase inhibitors slow down the growth of cancer cells. 

This medication works by targeting and blocking receptors found on the cancer cells called an anaplastic lymphoma kinase (ALK). In some cancers, this receptor is overactive, causing cells to grow and divide too fast. By inhibiting ALK, this medication can slow or stop cell growth of cancer cells tumor growth. Your provider will test your tumor for this abnormality, which must be present in order to receive the medication.

How to Take Brigatinib

This medication is taken by mouth, in tablet form, taken once daily. It can be taken either with or without food. Tablets should be swallowed whole; do not break, crush or chew the tablets. If you miss a dose or vomit soon after taking your dose do not take a second dose. Rather, take your next dose at its scheduled time.

It is important to make sure you are taking the correct amount of medication every time. Before every dose, check that what you are taking matches what you have been prescribed.

Storage and Handling

Store your medication in the original container with the label. If you want to use a pillbox, talk to your pharmacist. Keep it in a dry place at room temperature unless your provider or pharmacist tells you otherwise. Keep containers out of reach of children and pets.

If a caregiver prepares your dose for you, they should consider wearing gloves or pour the pills directly from their container into the cap, a small cup, or directly into your hand. They should avoid touching the pills. They should always wash their hands before and after giving you the medication. Pregnant or nursing people should not prepare the dose for you. Ask your provider where to return any unused medication for disposal. Do not flush down the toilet or throw in the trash. 

Where Do I Get This Medication?

Insurance Information

This medication may be covered by your prescription plan. If you qualify, you may be able to get financial help through patient assistance programs (PAP). Co-pay cards may also be available to lower your out-of-pocket cost if you have commercial (not Medicare/Medicaid/Tricare) insurance.

Possible Side Effects

These are some of the most common or most serious side effects of this medication. Talk with your provider about the side effects you are having and how they can be managed.

Diarrhea

Diarrhea is when you pass three or more stools in a day. Your providers can suggest medications to relieve diarrhea. Do not take any medications to manage your diarrhea without talking to your provider first, as your stool may need to be tested. To manage it, try eating foods that are low in fiber and bland, like white rice and boiled or baked chicken. Try not to eat raw fruits, vegetables, whole grain breads, cereals, and seeds. Soluble fiber is a type of fiber found in some foods that helps absorb (soak up) fluid. Foods high in soluble fiber are applesauce, bananas (ripe), canned fruit, oranges, boiled potatoes, white rice, foods made with white flour, oatmeal, cream of rice, cream of wheat, and farina. Stay hydrated by drinking 8 to 10 glasses of non-alcoholic, non-caffeinated fluid each day.

Rash

Some patients may develop a rash, scaly skin, or red itchy bumps. Use an alcohol-free moisturizer on your skin and lips; avoid moisturizers with perfumes or scents. Your provider can recommend a topical medication if itching is bothersome. If your skin does crack or bleed, be sure to keep the area clean to avoid infection. Be sure to notify your provider of any rash that develops, as this can be a reaction. They can give you more tips on caring for your skin.

Nausea and/or Vomiting

Talk to your providers if you have nausea and/or vomiting. They can prescribe medications to help you. Making changes to your diet can also help. Avoid things that make your symptoms worse, like heavy or greasy/fatty foods and spicy or acidic foods, like tomatoes, lemons, and oranges. Try saltines or ginger ale to help your symptoms.  

Call your providers if you cannot keep fluids down for more than 12 hours or if you feel lightheaded or dizzy.

Fatigue

Fatigue can cause exhaustion, feeling worn out and that your body is "heavy" and hard to move, or being unable to focus. It is common when you have cancer, and it is not the same as feeling tired. You may need to adjust your schedule to manage fatigue. Plan times to rest during the day and save your energy for more important activities. Exercise can help lessen fatigue. Talk to your providers about ways to deal with this side effect.

Muscle or Joint Pain/Aches and Headache

Your healthcare provider can recommend medications and other strategies to help relieve pain.

High Blood Sugar

This medication can cause high blood sugar in patients with and without diabetes. Symptoms can be:

  • Feeling more thirsty.
  • More frequent urination.
  • Feeling hungrier. 
  • Blurry vision.
  • Headaches.
  • Breath smelling like fruit.

All patients will have their blood sugar checked with blood tests. If you have diabetes and your blood sugars are higher than normal, talk to your provider. Tell your provider if you have any of these symptoms.

Decrease in Appetite or Taste Changes

Nutrition is an important part of your care. Cancer treatment can affect your appetite and make it hard to eat. Ask your provider about nutrition counseling services. Some tips you can follow are:

  • Try to eat five or six small meals or snacks during the day, instead of 3 larger meals.
  • Nutritional supplements may help if you are not eating enough.
  • You may have a metallic taste or find that food has no taste. You may dislike foods or beverages that you liked before cancer treatment. These symptoms can last for months or longer after treatment ends.
  • Avoid any food that you think smells or tastes bad. If red meat is a problem, eat chicken, turkey, eggs, dairy products, and fish without a strong smell. Sometimes cold food has less of an odor.
  • Add extra flavor to meat or fish by marinating it in sweet juices, sweet and sour sauce, or dressing.
  • Use seasonings like basil, oregano, or rosemary to add flavor.

Reproductive Concerns

There is a higher risk of health problems for your baby if you are pregnant, become pregnant, or get someone pregnant while on this medication. To lower the risk of birth defects, you should use birth control (contraception) to avoid pregnancy. Talk with your provider about what kind of birth control is safest for you and your partner.

If you can become pregnant, you will need to use non-hormonal birth control during treatment and for 4 months after the last dose of this medication, even if your menstrual cycle has stopped or changed.

If you can get someone pregnant, you will need to use effective birth control during treatment and for 3 months after the last dose of this medication, even if you believe you are not producing sperm.

You should not breastfeed during treatment and for 1 week after the last dose of this medication.

Important but Less Common Side Effects

Interstitial Lung Disease/Pneumonitis

This medication can cause inflammation (swelling and irritation) of your lungs, called pneumonitis. It can also cause scarring of your lungs, called interstitial lung disease, especially during the first week of taking this medication. If you have any new or worsening symptoms, like shortness of breath, cough (with or without mucous), fever, or chest pain, call your provider right away. If you are finding it hard to breathe, call 911 right away.

High Blood Pressure

This medication can cause high blood pressure (hypertension). You should have your blood pressure checked after 2 weeks of therapy, and then monthly while taking this medication so that if you have high blood pressure, it can be treated. If your blood pressure cannot be controlled, your provider may want you to stop taking the medication. Tell your providers about any headaches, vision changes, or dizziness. 

Bradycardia

Bradycardia is when your heart rate, or how fast your heart beats, is lower than normal. When your heart rate is 60 beats per minute (BPM) or less at rest, you are bradycardic. Call your provider if you feel:

  • Dizzy, especially when changing positions.
  • Lightheaded.
  • Short of breath.
  • More tired than normal.
  • Pain in your chest.
  • Like you might faint.

Your provider will monitor your heart rate during and after treatment.

  • Light bothering your eyes.
  • Seeing floaters (spots).
  • Loss of vision.

Call your provider right away if you have any changes to your eyesight. You may need to have an eye exam before or during treatment.

Elevated Creatine Phosphokinase

This medication can lead to an elevated level of the enzyme creatine phosphokinase (CPK) in your blood. This level will be checked during treatment with blood tests. If you start to experience muscle pain, tenderness, or weakness, notify your health care provider as these can be signs of elevated CPK.

Pancreatic Enzyme Elevations 

This medication can cause inflammation of the pancreas, which can cause upper abdominal pain that can radiate to the back that is worse with eating. You may also experience weight loss or nausea. You will have lab work drawn to monitor for pancreatitis. If you experience any of these side effects you should notify your health care provider.

Sun Sensitivity

This medication can make your skin more sensitive to the sun, which can result in a severe sunburn or rash. Sun sensitivity can last even after you are done with chemotherapy. Avoid the sun between 10 am and 4 pm, when it is strongest. Wear sunscreen every day and reapply when you are in the sun. The best sunscreen is SPF 30 or higher and protects against both types of sunlight, UVA and UVB. Wear sunglasses, a hat, and long sleeves/pants to protect your skin, a lip balm with SPF greater than 30, and seek out shade whenever possible.

Tell your providers if you develop red, painful, or itchy skin, sunburn, skin irritation, bumps, or thick, dry skin.

Liver Toxicity

This medication can cause liver toxicity, or liver problems, which your provider may monitor for with blood tests called liver function tests. Symptoms may be:

  • Yellowing of your skin or eyes.
  • Dark or brown urine.
  • Pain in your abdomen (belly).

Tell your provider if you have any of these symptoms.
