Uses
What is Elevidys used for?
Elevidys (delandistrogene moxeparvovec-rokl) is commonly used to treat Duchenne muscular dystrophy (DMD). DMD is a progressive, genetic disease that affects muscles, causing them to become weaker over time.
Learn more about Elevidys for Duchenne muscular dystrophy (DMD).
Elevidys may also be used for other conditions as determined by your healthcare provider.
How does Elevidys work (mechanism of action)?
In DMD, you have a change in your genes, which is called a genetic mutation. This change causes the dystrophin protein to not work correctly. Your muscles need dystrophin to stay healthy and be strong. With less dystrophin, muscles become weak over time.
Elevidys uses a special tool, called a vector, to deliver a version of dystrophin to your muscles. It signals your body to make more dystrophin, which helps keep muscles stronger for a longer time.
How is Elevidys supplied (dosage forms)?
Elevidys is available in an injectable form that is given by a healthcare provider.
How should I store Elevidys?
Elevidys is usually given by a healthcare provider in a hospital or clinic. You will not store it at home.

What are the serious side effects of Elevidys?
While less common, the most serious side effects of Elevidys are described below, along with what to do if they happen.
Severe Allergic Reactions. Elevidys may cause allergic reactions, which can be serious. Tell your healthcare provider right away if you are having any of the following symptoms of a serious allergic reaction.
- Breathing problems or wheezing
- Racing heart
- Fever or general ill feeling
- Swollen lymph nodes
- Swelling of the face, lips, mouth, tongue, or throat

Infusion Reactions. Elevidys can cause reactions that can be serious when it is given to you or for up to several hours afterward. Your infusion may need to be slowed or stopped. Tell your healthcare provider right away if you have any of the following symptoms when you get your infusion.
- Fast heart rate
- Trouble breathing or fast breathing
- Itchy or swollen lips
- Hives, rash, or red and blotchy skin
- Nausea or vomiting
- Fever or chills
- Widening nostrils
Liver Damage. Liver damage, also called hepatotoxicity, can happen when taking Elevidys. Your healthcare provider will monitor the health of your liver by checking blood tests, called liver function tests (LFTs). Call your healthcare provider right away if you have any of the following symptoms of liver damage.
- Nausea or vomiting
- Stomach or belly pain
- Fever
- Weakness or unusual tiredness
- Itching
- Loss of appetite
- Light-colored poop
- Dark-colored urine (pee)
- Your skin or the whites of your eyes turning yellowish in color (also called jaundice)
Inflammation in Muscles. Some conditions and medicines, like Elevidys, can cause myositis, which is inflammation in muscles. When using new gene medicines, the immune system may ramp up and cause more inflammation as it tries to “fight off” the new medicine. When this inflammation affects the muscles, you may experience more weakness, swelling, and pain. Contact your healthcare provider right away if you have any of the following symptoms of myositis.
- Increased muscle weakness
- Muscle pain or tenderness
- Trouble swallowing (dysphagia)
- Trouble breathing or shortness of breath (dyspnea)
- Difficulty talking or not able to speak loudly or clearly
Inflammation of the Heart Muscle. Myocarditis is when your heart muscle becomes inflamed or irritated. This can affect how well your heart pumps blood. Elevidys can cause the immune system to produce more inflammation around the heart muscle. Your healthcare provider may do blood tests to check for damage to the heart muscle. Contact your healthcare right away if you have the following symptoms of heart damage.
- Chest pain
- Shortness of breath or difficulty breathing
Severely Low Platelet Levels. Elevidys can cause you to have a severely low number of platelets in your blood, also called thrombocytopenia. Platelets help to form blood clots. Having a low level of platelets may increase your risk of bleeding. Tell your healthcare provider if you have any of the following symptoms of low platelet levels.
- Easy bruising or bleeding
- Bleeding that does not stop
- Nosebleeds
Warnings & Precautions
Who should not use Elevidys?
Allergies to Ingredients. People who are allergic to any of the following should not use Elevidys.
- Elevidys
- Delandistrogene moxeparvovec-rokl
- Any of the ingredients in the specific product dispensed
Your healthcare provider can tell you all the ingredients in Elevidys.
Genetic Variations. People with DMD can have different variations in the DMD gene, also called mutations. Elevidys should not be used if you have specific genetic mutations. Your healthcare provider may test you for these mutations before using Elevidys.
Antibodies. Your immune system uses antibodies to protect you from illness. Elevidys uses a special tool, called a vector, to deliver a version of the dystrophin protein to your muscle cells. Some people may have antibodies to this vector. If they have too many antibodies to the vector, it may stop Elevidys from working correctly or cause serious side effects.
