Beleodaq (belinostat) is an anticancer medication used to treat relapsed or advanced peripheral T-cell lymphoma (PTCL) in adults. It’s given as an intravenous (IV) infusion, usually once daily for five days in a 21-day treatment cycle. Your oncology team will decide how many cycles you need based on how well this medication treats the cancer and whether you have any serious side effects. Some common side effects of Beleodaq (belinostat) include nausea and tiredness. It can also cause a rare, but serious condition called tumor lysis syndrome.

What is Beleodaq (belinostat) used for?

How Beleodaq (belinostat) works

In some cancer cells, such as lymphoma cells, certain proteins help send messages that tell the cells to grow and spread. One of these proteins is called histone deacetylase (HDAC).

Beleodaq (belinostat) is a histone deacetylase (HDAC) inhibitor. It blocks the histone deacetylase protein, which stops it from sending messages to the cell. When this protein is blocked, cancer cells don’t grow and spread as well.

Pharmacist tips for Beleodaq (belinostat)

pharmacist
  • Beleodaq (belinostat) might cause nausea. Your oncologist will prescribe antiemetics for you to take in between doses to manage this side effect, such as prochlorperazine (Compazine) or ondansetron (Zofran). If you have nausea or vomiting that doesn’t get better with medication, contact your healthcare team.

    • You might experience diarrhea while taking Beleodaq (belinostat). Your oncologist might recommend an over-the-counter medication such as loperamide (Imodium A-D) to help manage diarrhea. If you experience diarrhea it’s important to drink a lot of fluids, but try to avoid sugary sports drinks because they can make diarrhea worse.

      • This medication can raise your risk for getting sick, so you should check your temperature regularly. Call your provider right away if your temperature is 100.4 degrees Fahrenheit or higher. This means you have a fever, and this might be the only sign that you’re sick.

        • If you’re a male, Beleodaq (belinostat) might affect your fertility, or ability to have children, in the future. Talk with your provider about fertility preservation options such as sperm banking.

          • Sometimes, taking Beleodaq (belinostat) can cause your liver to become irritated. Your oncologist will order lab tests to check your liver health before the start of each treatment cycle because people who experience this side effect often don’t feel any symptoms. But if you have stomach pain, yellowish skin, or yellow around the whites of your eyes, call your oncologist right away.

            • We don’t know if Beleodaq (belinostat) passes into human milk. But, based on the way this medication works, it might harm a nursing infant. You shouldn’t breastfeed while taking Beleodaq (belinostat) and for 2 weeks after the last dose.

              faqs

              Frequently asked questions about Beleodaq (belinostat)

              Is Beleodaq (belinostat) chemotherapy?
              Sort of. Beleodaq (belinostat) can be considered a type of chemotherapy. But it works differently from traditional chemotherapy medications, which directly attacks all fast-growing cells (including healthy cells). Beleodaq (belinostat) is histone deacetylase (HDAC) inhibitor and it targets cancer cells by blocking a specific protein that cancer cells typically depend on to grow and spread. Research suggests it isn't likely to affect healthy cells. This makes Beleodaq (belinostat) a more targeted therapy compared to traditional chemotherapy.
              How long should I take Beleodaq (belinostat) for?
              You should take Beleodaq (belinostat) as recommended by your oncology team. Typically, they’ll ask you to continue as long as it’s working to treat the cancer and you’re able to tolerate the side effects. Your oncologist will monitor how well the medication is working for you based on lab tests, scans, and your symptoms. Don’t stop taking Beleodaq (belinostat) without first talking to your oncology team.
              Does Beleodaq (belinostat) affect my immune system?
              Yes, Beleodaq (belinostat) can weaken your immune system and raise your risk of serious infections. This is because this medication can cause your blood cell counts to drop, including your white blood cell (WBC) counts. Your WBCs help your body fight infection, so when their levels are low, you’re more likely to get sick. Because of this risk, your oncology team will order blood tests weekly to check your blood cell counts. If your levels drop too low, your team might lower your dose of Beleodaq (belinostat) or talk with you about other treatment options. Let your care team know right away if you have symptoms of an infection, such as fever, chills, or body aches. It’s important to check your temperature regularly because sometimes a fever is the only sign you’re sick.
              What’s the most common side effect of Beleodaq (belinostat)?
              The most common side effect of Beleodaq (belinostat) is nausea. Vomiting is also possible, but is less common. Typically, your oncologist will prescribe antiemetics for you to take before each dose of Beleodaq (belinostat) to prevent nausea and vomiting. They might also send home medications such as ondansetron (Zofran) or prochlorperazine (Compazine) for you to take as needed if you feel nauseous after you get home. If you have nausea that doesn’t get better with medication, contact your oncology team.
              Will I lose my hair if I take Beleodaq (belinostat)?
              Most people taking Beleodaq (belinostat) don’t lose their hair. You might experience mild or moderate hair thinning or loss during treatment, but hair usually grows back after you stop taking the medication. Let your oncologist know if you have hair loss, because there might also be other causes they want to look into.
              Can I take Beleodaq (belinostat) if I have liver problems?
              Let your oncology team know if you have liver problems. You might be able to take Beleodaq (belinostat) if your condition is mild, but your oncologist might need to talk with you about other treatment options if you have serious liver problems. This is because Beleodaq (belinostat) is processed by the liver, so if you have liver problems, you might be at higher risk for side effects. In addition, this medication can cause liver problems, such as liver irritation. Before you start treatment, your oncologist will order a lab test to check your liver health. They’ll continue to check your liver regularly before the first dose of each cycle. Let your care team know if you notice symptoms of liver problems, such as stomach pain, tiredness, or yellowing of the skin or the whites of the eyes.

              What are the risks and warnings for Beleodaq (belinostat)?

              Beleodaq (belinostat) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

              risk-warning

              Low blood cell counts

              People taking Beleodaq (belinostat) have experienced low blood cells, such as white blood cells, red blood cells, and platelets. When your blood cell counts are low, you’re at higher risk for certain conditions, such as serious infections or bleeding that’s difficult to stop.

              To be safe, your oncologist will monitor your blood cell counts with lab tests weekly while you’re taking Beleodaq (belinostat). If your results are too low, they’ll adjust your dose or ask you to pause taking Beleodaq (belinostat) until your blood cell counts are within a safe range. Contact your healthcare team if you have symptoms of low blood cells such as fever, severe tiredness, or bruising that won’t go away or bleeding that’s difficult to stop.

              risk-warning

              Infections

              • Risk factors: Previous chemotherapy

                People taking Beleodaq (belinostat) have reported serious infections, including pneumonia and sepsis. You might be at higher risk for serious infections if you’ve previously received chemotherapy. Your healthcare team will monitor you closely for infections. Get medical help right away if you have symptoms of a serious infection such as fever, body aches, or chills.

                risk-warning

                Serious liver problems

                Beleodaq (belinostat) can cause liver problems. People who experience this might not notice any symptoms, but will have higher liver enzymes levels on their lab work, which suggests liver irritation. Rarely, liver problems can become life-threatening.

                Your oncologist will check your liver health with lab tests before you start Beleodaq (belinostat) and at the start of each treatment cycle. If your liver enzyme level is too high, your oncologist might adjust your dose of Beleodaq (belinostat) or pause treatment until the levels return to a safe range. But if you develop severe liver problems, your oncologist will ask you to stop taking Beleodaq (belinostat) and talk with you about other options. Contact your oncology team as soon as possible if you have symptoms of liver damage, such as tiredness, stomach pain, and yellowing of the skin or whites of the eyes.

                risk-warning

                Tumor lysis syndrome

                It’s possible for people taking Beleodaq (belinostat) to develop a complication called tumor lysis syndrome (TLS). This happens when cancer cells are destroyed and release what’s inside of them into your blood. This can cause high levels of potassium and uric acid in your blood, which can cause problems in your heart and kidneys.

                Your oncology team will monitor you closely for signs of TLS. They might also give you extra fluids or medications such as allopurinol (Zyloprim) to prevent this complication. Let your care tea know right away if you experience symptoms of TLS, such as nausea, tiredness, and dark-colored urine.

                risk-warning

                Nausea, vomiting, and diarrhea

                Some people taking Beleodaq (belinostat) experienced stomach and intestine problems such as nausea, vomiting, and diarrhea. To manage nausea and vomiting, your oncologist might give you medications through your IV before each dose of Beleodaq (belinostat). They might also send home oral antiemetics for you to take in between doses.

                If you experience diarrhea while taking Beleodaq (belinostat), ask your oncology team whether it’s safe for you to take over-the-counter medications to ease your symptoms. Make sure you drink plenty of fluids if you have diarrhea. If you have nausea, vomiting, or diarrhea that doesn’t get better with medications, contact your healthcare team.

                risk-warning

                Harm to unborn baby

                • Risk factors: Pregnancy

                  Beleodaq (belinostat) might harm an unborn baby or raise the risk of pregnancy loss (miscarriage). If you’re a female who is able to have babies, your oncologist might ask you to take a pregnancy test before you start treatment to check that you’re not pregnant. You should use effective birth control while taking Beleodaq (belinostat) and for 6 months after the last dose. If you’re a male who is sexually active with a female, you should use birth control such as condoms while taking Beleodaq (belinostat) and for 3 months after the last dose.
