New hope for duchenne: experimental drug targets genetic flaw
NCT ID NCT07037862
First seen Jun 26, 2026 · Last updated Aug 14, 2026 · Updated 3 times
Summary
This study tests an investigational drug called ENTR-601-44 in 24 boys and young men with Duchenne muscular dystrophy (DMD) whose genetic mutation can be treated by skipping a specific part of the gene (exon 44). The trial has two parts: first, to find the safest and most effective dose, and second, to check how well it works. Participants receive multiple IV infusions and are monitored with blood tests, muscle biopsies, and physical exams.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ENTR-601-44 (a drug designed to help muscle cells produce a shortened but functional dystrophin protein)
- What this could lead to
- If successful, this could lead to a treatment that slows muscle decline and improves function in people with Duchenne muscular dystrophy who are eligible for exon 44 skipping.
- What could go wrong
- This is an early-phase trial with only 24 participants, so results may not apply to everyone. The drug may cause side effects or fail to show meaningful benefit.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Principal inclusion criteria 1. Genetic diagnosis of Duchenne muscular dystrophy (DMD) and confirmed pathologic variant in the dystrophin gene amenable to exon 44 skipping as reviewed by a central genetic counselor. 2. Assigned male at birth with clinical signs compatible with Duchenne muscular dystrophy as determined by the investigator. 3. Part A: 4-20 years of age, inclusive. 4. Ambulatory Status Part A: ambulatory with a Performance of the Upper Limb v2.0 (PUL 2.0) Entry as per protocol at Screening 5. Adequate muscle for obtaining tissue biopsy as assessed by the investigator. 6. Other protocol-defined criteria apply. Principal exclusion criteria 1. Any significant concomitant medical condition that might interfere with the ability to comply with protocol requirements. 2. Has an acute illness within 4 weeks prior to the first dose of study drug which may interfere with study measurements or jeopardize participant's safety. 3. Use of the following medications: 1. Prior treatment with any exon skipping therapy at any time 2. Prior treatment with any gene therapy at any time 3. Use of anti-coagulants, anti-thrombotics, or anti-platelet agents 4. Use of an immunosuppressants (other than oral corticosteroids for DMD conditions) 5. Has taken or is currently taking a histone deacetylase (HDAC) inhibitor, including (but not limited to) givinostat 4. Laboratory abnormalities. 5. Daytime ventilator dependence or any use of invasive mechanical ventilation via tracheostomy. 6. Has an abnormal electrocardiogram (ECG) reading assessed as clinically significant by the investigator, and/or a QT interval with Fridericia correction method (QTcF) \>450 msec at Screening or prior to the first dose of study drug on Day 1. 7. Received any experimental or investigational drug, etc. within 3 months prior to first dose or within 5 half-lives (whichever is longer). 8. Other protocol-defined criteria apply.
