Aqneursa (levacetylleucine) is an amino acid derivative used to treat the neurological symptoms of Niemann-Pick Disease type C (NPC), such as difficulty walking and speaking. Aqneursa (levacetylleucine) comes as a powder packet that can be dissolved in water, orange juice, or almond milk. This medication is taken by mouth 2-3 times a day, as directed by your healthcare team. Common side effects include upper respiratory infections, stomach pain, and difficulty swallowing.
Niemann-Pick Disease type C (NPC) is a genetic condition that’s caused by the body not being able to properly move and store cholesterol and other fats inside the body. Typically, cells have the ability to break down fats. But people with NPC have faulty proteins that prevent this process from happening. This leads to fats building up in various parts of the body, including the brain.
Aqneursa (levacetylleucine) is an amino acid derivative. Amino acids make up proteins that help your body with important functions. Sometimes, amino acids can be chemically changed in labs to help treat certain medical conditions. Aqneursa (levacetylleucine) is made up of an amino acid that’s been changed to help the cells make more energy. It’s thought that when cells have more energy, they’re better able to process the fat buildup. And this might help ease some symptoms of NPC.

More tips for taking AQNEURSA
Niemann-Pick disease type C (NPC) is a genetic condition that’s caused by the body not being able to store cholesterol and other fats properly. As a result, they build up in different parts of the body, including the brain. This can lead to a variety of symptoms, including enlarged spleen or liver, difficulty speaking, trouble walking, and seizures. Symptoms typically worsen over time. The main way to treat NPC is by managing the symptoms. People who have NPC usually see multiple healthcare professionals to help. For example, they might work with occupational or physical therapists regularly to maintain or improve the ability to swallow and move around. Aqneursa (levacetylleucine) is one of two medications that’s FDA-approved to treat the neurological symptoms of NPC .
There’s no cure for NPC, but Aqneursa (levacetylleucine) may help with the certain symptoms of this condition. A study showed that people who take Aqneursa (levacetylleucine) might have some improvement with speaking, walking, and other movements. In general, treatments for NPC focus on easing the symptoms of this condition.
Ask your healthcare team how long you should take Aqneursa (levacetylleucine). Currently, guidelines for NPC don’t recommend a specific length of time to take this medication. But people who took Aqneursa (levacetylleucine) in the clinical study received treatment for about 3 months. So your healthcare team may ask you to try this medication for at least 3 months as well to see if it works for you. But they might ask you to stop this medication earlier if the side effects, such as vomiting or stomach pain, are too severe. Speak with your healthcare team before making any changes to your medication.
In a clinical study, researchers looked at how well Aqneursa (levacetylleucine) worked by scoring people based on how well they can do certain activities, including walking, sitting, and speaking. Results showed that when people took Aqneursa (levacetylleucine) for 3 months, they had more improvement in symptoms than when they took placebo. Though more research is needed, another study suggests that some people might experience improvements after taking Aqneursa (levacetylleucine) for 6 weeks. Ask your healthcare team about what you might expect after starting treatment.
If you experience vomiting after taking Aqneursa (levacetylleucine), let your healthcare team know. They'll talk with you about the next steps depending on how severe your symptoms are and how often you're vomiting. In general, vomiting raises your risk of losing too much fluid, which can cause you to become dehydrated and experience dizziness or fainting. Your care team will recommend ways for you to stay hydrated, such as drinking water and sports drinks to replenish fluids and electrolytes in your body. But if you continue experiencing nausea or vomiting and your symptoms make it difficult to hold down food or medication, your healthcare team might talk with you about other treatment options.
Yes, you can give Aqneursa (levacetylleucine) through a type of feeding tube called the gastrostomy tube (G-tube) that’s French size 18 or larger. To do so, first mix the medication into an oral suspension as directed by your healthcare team. Then draw it up using a G-tube syringe and inject it through the feeding tube right away. Afterwards, flush the tube with 20 mL of water to make sure no medication gets stuck in the tube. If needed, flush the feeding tube again until you no longer see any leftover suspension inside.
Aqneursa (levacetylleucine) 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.
Aqneursa (levacetylleucine) might cause harm to unborn babies. While this medication hasn’t been studied in human pregnancies, animal studies showed that Aqneursa (levacetylleucine) can cause miscarriage and developmental issues during pregnancy.
If you are able to get pregnant, your healthcare team will ask you to take a pregnancy test before starting Aqneursa (levacetylleucine). Because of the possible risk of harm, they’ll recommend that you use effective birth control during treatment and for at least a week after your last dose. If you’re pregnant or planning to become pregnant, discuss with your healthcare team about the risks and benefits of taking this medication during pregnancy.
