Scemblix (asciminib) is an oral medication used to treat certain types of chronic myelogenous leukemia (CML). It’s considered a type of targeted anticancer treatment. This medication is conveniently taken once or twice a day, but it can cause mild allergic reactions like rash, swelling, and wheezing.
Scemblix (asciminib) is a tyrosine kinase inhibitor (TKI). It blocks a certain protein in your body called BCR-ABL tyrosine kinase. This protein is found on cancer cells like CML and not on normal, healthy cells. It causes the cancer cells to grow and multiply. By blocking this protein, Scemblix (asciminib) kills cancer cells and stops their spread.
The following side effects may get better over time as your body gets used to the medication. Let your healthcare provider know immediately if you continue to experience these symptoms or if they worsen over time.
Contact your healthcare provider immediately if you experience any of the following.
Side effects that you should report to your care team as soon as possible:
Side effects that usually do not require medical attention (report these to your care team if they continue or are bothersome):
The Philadelphia chromosome is a specific type of mutation that’s found in the cancer cells of many people with CML. A mutation is an abnormal change in the cell’s genetic material. Having the Philadelphia chromosome mutation can determine how your cancer is treated. Your provider will test your cancer cells to see if you have this particular mutation. If you do, then your cancer is considered Philadelphia-positive (Ph+) and Scemblix (asciminib) could be an option for you.
Scemblix (asciminib) is used to treat Ph+ CML in certain situations. Typically, people try other TKIs — like Bosulif (bosutinib), Sprycel (dasatinib), and Tasigna (nilotinib) — to treat their cancer first. But over time, the cancer can change in a way that makes it no longer respond to these medications. When these TKIs don’t work anymore, Scemblix (asciminib) can be another option. In addition, some people have Ph+ CML with a specific mutation called T315I, which is particularly hard to treat. Scemblix (asciminib) is one of the few recommended medications that can fight Ph+ CML with this mutation. Your provider will decide if Scemblix (asciminib) is best for your specific type of cancer.
It’s important that you take Scemblix (asciminib) on an empty stomach because food affects how much Scemblix (asciminib) gets absorbed into your body. If you take it with food, your body might not absorb enough medication. This can affect how well Scemblix (asciminib) works to treat your cancer.
You should take Scemblix (asciminib) as instructed by your provider. How long you take Scemblix (asciminib) therapy depends on several factors, including how well the medication is working to treat your cancer and how well you tolerate it. Don’t stop taking Scemblix (asciminib) without first discussing with your provider.
It isn’t recommended to breastfeed while taking Scemblix (asciminib). We don’t know if the medication can pass into human breast milk, but there’s a risk of serious harm to nursing infants if it does. Because of this risk, you shouldn’t breastfeed while taking Scemblix (asciminib) and for 1 week after your last dose. Talk with your provider about other ways to feed your baby during treatment.
Scemblix (asciminib) 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.
Scemblix (asciminib) can cause the levels of your red blood cells, white blood cells, and platelets to drop. When these cell counts are lower than normal, you have a higher risk of anemia, bleeding, bruising, and infections. Your provider will check your blood counts often while you’re taking Scemblix (asciminib). Let your provider know right away if you experience fevers, chills, or bleeding and bruising that doesn’t stop or go away because you might need to have your dose lowered or stop this medication.
Some people taking Scemblix (asciminib) can develop higher blood levels of lipase and amylase (proteins that your pancreas makes). These elevated levels can occur with or without pancreatitis. If you’ve had pancreatitis before, you might be at higher risk of developing it again during treatment. Your provider will monitor your lipase and amylase levels while you’re taking Scemblix (asciminib) and adjust your dose if they get too high. Let your provider know immediately if you have sudden pain in your stomach that happens with nausea and vomiting. This can be a symptom of pancreatitis.
About one in three people taking Scemblix (asciminib) have an allergic reaction. The reactions are typically mild in severity. Seek immediate medical attention if you develop symptoms of an allergic reaction. These reactions can include trouble breathing or swallowing, swelling of the face, rash, fever, fast heartbeat, or dizziness. If necessary, your provider can recommend ways to ease these allergic reactions, adjust your Scemblix (asciminib) dose, or recommend you to pause treatment.
Scemblix (asciminib) can cause problems like heart failure, heart attack, stroke, blood clots, or changes in your heartbeat. Although it’s possible, these problems are rarely serious or life-threatening. If these events happen, your provider might change your dose or stop your Scemblix (asciminib) therapy. Get medical help right away if you develop any symptoms related to these heart or blood vessel problems. Symptoms can include shortness of breath; chest pain; fast heartbeat; swelling in your ankles or feet; numbness on one side of your body; vision changes; severe stomach area pain; or pain in your arms, legs, back, neck, or jaw.
Based on animal studies, Scemblix (asciminib) can harm an unborn baby or raise the risk for miscarriage (pregnancy loss). Because of this risk, if you’re female and are able to become pregnant, you should take a pregnancy test before starting treatment to make sure you’re not pregnant. Also use birth control while taking Scemblix (asciminib) and for at least 1 week after your last dose. Let your provider know right away if you become pregnant during this time.
