Let’s sail through Duchenne Muscular Dystrophy (DMD) research together!
The EXPLORE44™ study is focused on testing a new investigational drug as a treatment option for Duchenne Muscular Dystrophy (DMD). If you are 7 to 27 years old with a diagnosis of DMD due to a mutation amenable to exon 44 skipping, consider coming aboard this study to evaluate an investigational drug that is designed to treat the underlying cause of DMD.
Who Is Eligible to Participate in This Study?
You or a loved one may qualify if you or they:
- Are male and between the ages of 7 to 27 years
- Have been clinically diagnosed with DMD or had a clear onset of DMD symptoms at or before the age of 6 years old
- Have a gene mutation amenable to exon 44 skipping
- Weigh ≥ 23 kg (50.7 lbs.)
- Ambulatory or non-ambulatory
- Currently taking stable doses of steroids or not taking steroids
Additional requirements to participate will apply. A study representative will discuss them with you during the Screening Visit.
What is Duchenne Muscular Dystrophy (DMD)?
DMD almost always occurs in boys, and signs can start to appear between 1 and 3 years of age. Muscles in the lower body, like calf and thigh muscles, are usually affected first. As DMD progresses, muscle weakness can affect the ability to do everyday tasks including walking and ultimately impacts life expectancy due to weakness of the breathing muscles and the heart.
Even though there has been no cure yet, there are therapies that can help manage DMD.
Common symptoms may include:
- Muscle weakness
- Difficulty running, jumping, climbing stairs
- Falling
- Difficulty rising from a sitting position
- Muscle pain or stiffness
- Enlarged calf muscles

What to Expect During the EXPLORE44™ Study
To participate in this study, participants will be asked to read and sign an Informed Consent Form (ICF).
The form explains:
- The purpose of the study
- Required study visits and procedures
- Potential risks and benefits of participation
- Confidentiality
- How participant and caregiver personally identifiable information will be used
- Information on how to withdraw from the study
Both investigational drug and placebo will be given by intravenous infusions approximately either every 6 or 8 weeks. The study is blinded, meaning that neither you nor the study team will know which study treatment you are receiving. However, the study doctor can quickly find out if there is a medical need.
Safety is our top priority, and that’s why study teams will monitor the health of all participants closely. We’ll make sure participants are doing well through various procedures and checks.
Some of the planned assessments and procedures include:
- Health Questions
- Physical Examinations
- Vital Signs
- Blood and Urine Sample Collections
- Electrocardiogram (ECG)
- Spirometry
- Echocardiogram
- Skeletal Muscle Open Biopsies
- Genetic Testing
- Muscle Function Tests
- Patient/Caregiver Reported Outcomes
Participants will be enrolled in the EXPLORE44™ study for up to 8 months, including screening.
Avidity Biosciences is also planning an Open-Label Extension (OLE) study, in which all eligible participants who have completed the EXPLORE44™ study will receive the active study drug for an ongoing period.
Travel support and reimbursement for the participant and a caregiver will be provided while participating in the study.
