VYONDYS 53 is used to treat patients with Duchenne muscular dystrophy (DMD) who have a confirmed mutation in the dystrophin gene that can be treated by skipping exon 53. VYONDYS 53 treatment increased the marker, dystrophin, in skeletal muscle in these patients with DMD.
VYONDYS 53 is used to treat patients with Duchenne muscular dystrophy (DMD) who have a confirmed mutation in the dystrophin gene that can be treated by skipping exon 53.
This indication is approved under accelerated approval based on an increase in dystrophin production in skeletal muscle observed in patients treated with VYONDYS 53. Continued approval for this indication may be contingent upon verification of a clinical benefit in confirmatory trials.
Patients who receive VYONDYS 53 must have a genetic test that shows a mutation in the dystrophin gene that can be treated by skipping exon 53. A healthcare provider is needed to interpret your genetic test to determine whether you can take VYONDYS 53.
Adverse reactions that have occurred in at least 20% of patients treated with VYONDYS 53 and more often than in patients who received an inactive intravenous (IV) infusion were headache (41%, 10%), fever (41%, 14%), fall (29%, 19%), pain in the abdomen (27%, 10%), infection of the nose and throat (27%, 14%), cough (27%, 19%), vomiting (27%, 19%), and nausea (20%, 10%).
You should talk with your doctor about all the medications you are taking. Your doctor is the best person to advise you about your medicines.
VYONDYS 53 is supplied in 2 mL single-dose vials containing 100 mg golodirsen (50 mg/mL). The solution is a clear to slightly opalescent, colorless liquid and may contain trace amounts of small, white to off-white amorphous particles.
The amount of VYONDYS 53 you will be given is based upon how much you weigh. The recommended dosage of VYONDYS 53 is 30 milligrams per kilogram of body weight, intravenously (IV) infused, once weekly over 35-60 minutes via in-line 0.2 micron filter.
VYONDYS 53 will be intravenously infused over 35-60 minutes via an in-line 0.2 micron filter.
If a dose of VYONDYS 53 is missed, it may be administered as soon as possible after the scheduled dose. Talk to your doctor if you miss a dose.
You may receive your infusions at an infusion center or your home. You and your doctor may need to discuss these options, including whether home therapy is an option for you.
VYONDYS 53 is given by intravenous (IV) infusion once a week via an in-line 0.2 micron filter. An IV infusion is a way of delivering medicine directly into your bloodstream through a vein. Your doctor may discuss the use of a port, which is a device installed under the skin for repeat use in delivering IV medications. VYONDYS 53 infusion is always given and monitored by a healthcare provider.
Ask your doctor for any patient instructions provided by the maker of your port. Carefully follow these or other instructions provided by your doctor for care of your port site to reduce the risk of complications, including infections.
*Always refer to the manufacturer’s instruction for use (IFU) guide for more information on safety and precautions and ask your health care provider to review the relevant instruction for use of your port with you.
Your doctor or the maker of your port may recommend hygiene measures after placement of the port and after each use of the port. Carefully follow these and other instructions provided by your doctor.
*Always refer to the manufacturer’s instruction for use (IFU) guide for more information on safety and precautions and ask your health care provider to review the relevant instruction for use of your port with you.
Follow instructions from the maker of your port and your doctor regarding when to contact your doctor. Always contact your doctor:
*Always refer to the manufacturer’s instruction for use (IFU) guide for more information on safety and precautions and ask your health care provider to review the relevant instruction for use of your port with you.
VYONDYS 53 is an exon-skipping therapy. The goal of exon skipping is to allow the body to make a shorter form of the dystrophin protein. Let’s take a closer look at how:
The dystrophin gene is the largest gene in the body, made up of 79 exons (portions of a gene) that are linked together to form the instructions for making dystrophin — a protein muscles need to work properly.
Think of the exons like toy train cars, each with a special connection that allows one car to connect to another. In order for all the cars to move together as a train, the connections between cars must match so that they can connect to one another.
Duchenne is caused by a genetic mutation, or change, in the dystrophin gene. Most commonly, one or more exons are missing. This causes errors in the instructions for making dystrophin, and the body is not able to produce enough or any working dystrophin protein.
Imagining the toy train, one or more cars would be missing, leaving the remaining cars not connected. In this example, we can see that cars 50–52 are missing. This results in cars 49 and 53 not being able to connect.
Exon skipping technology allows the body to make dystrophin protein by skipping over a specific exon. VYONDYS 53 works using exon skipping and the result is a shorter form of the dystrophin protein.
So with our train, we would move a certain car aside to “skip over” it so we could find a car with the right connection to allow the remaining cars to connect. In our example, car 53 would be skipped over to allow car 49 to connect to car 54.
Clinical studies of VYONDYS 53 tested whether exon skipping happened on the dystrophin gene of boys treated with the drug. In those studies, exon skipping occurred in all 25 evaluated study participants.

Allergic reactions, including rash, fever, itching, hives, and inflammation and/or peeling of the skin have occurred in patients who were treated with VYONDYS 53. Seek immediate medical care if signs and symptoms of allergic reactions occur.
Damage to the kidneys was seen in animals who received golodirsen. Although damage to the kidneys was not seen in clinical studies with VYONDYS 53, the clinical experience with VYONDYS 53 is limited. Fatal kidney damage has occurred with other drugs that work in a similar way. Your doctor may recommend urine collection and blood testing before starting treatment followed by urine testing every month and a blood test every 3 months to monitor your kidneys.
ADVERSE REACTIONS OBSERVED IN AT LEAST 20% OF TREATED PATIENTS AND GREATER THAN PLACEBO WERE (VYONDYS 53, PLACEBO)
Other adverse reactions that occurred in greater than 5% of patients treated with VYONDYS 53 and more often than in patients who received an inactive IV infusion were pain at the IV site, back pain, pain, diarrhea, dizziness, stretch or tear in a ligament, bruising, flu, pain in the mouth and throat, stuffy or runny nose, scrapes or scratches of the skin, ear infection, seasonal allergy, fast heartbeat, reactions related to the IV catheter site, constipation, and broken bones. Talk to your doctor if you experience any side effects.
