Study summary

Duchenne muscular dystrophy (DMD) is a devastating X-linked disease which leads to loss of ambulation between ages 7 and 13, respiratory failure and cardiomyopathy (CM) at any age, and inevitably premature death of affected young men in their late twenties. DMD is the most common fatal genetic disorder diagnosed in childhood. It affects approximately 1 in every 3,500 live male births across all races and cultures, and results in 20,000 new cases each year worldwide.Significant advances in respiratory care have unmasked CM as the leading cause of death. As there are yet no specific cardiac treatments to extend life, the current study aims to address this unmet medical need using a new therapeutic strategy for patients with DMD.

Read the detailed description

This is a phase 2 randomized, double-blind, placebo-controlled, multiple dose study with an optional open-label extension to determine the safety, pharmacokinetics (PK) and efficacy of two doses of oral ifetroban in subjects with DMD. DMD patients who meet the inclusion criteria and none of the exclusion criteria will receive oral ifetroban or placebo once daily for 12 months. Subjects will be enrolled into one of three treatment groups, low-dose ifetroban, high-dose ifetroban or placebo. Each dose level will be evaluated by eight subjects with early stage (LVEF > 45%) DMD-associated cardiomyopathy and eight subjects with more advanced stage (LVEF 35-45%) cardiac disease as there may be differences in the treatment effect based on cardiac involvement. Each subject treated will be evaluated for first-dose and steady-state exposure PK. All subjects who receive treatment will be assessed for safety. All subjects with at least one efficacy assessment post-baseline will be evaluated for efficacy. Blood and urine will be collected for standard and novel cardiac biomarkers. Target enrollment met for early-stage subjects (LVEF > 45%); study closed to enrollment prior to meeting target enrollment in the late-stage cohort (LVEF 35-45%). All subjects who complete the 12-month study are eligible to enter an optional open label extension period consisting of treatment with high-dose ifetroban only. Subjects in the open label extension will be evaluated for safety and cardiac efficacy every 12 months.

Inclusion criteria

  1. Males 7 years of age and older with the diagnosis of DMD, defined as phenotype consistent with DMD and either positive genotype, first degree relative with positive genotype, or confirmatory muscle .
  2. Stable dose of oral for at least 8 weeks or has not received corticosteroids for at least 30 days.
  3. Stable cardiac function defined as change in (LVEF) of \< 15% and no heart failure admission over the last 12 months; LVEF 35% or greater by cine cardiac magnetic resonance imaging (MRI) or echocardiography; myocardial damage in one or more left ventricular segments evident by late gadolinium enhancement allowed; concurrent angiotensin-converting enzyme inhibitors (ACEI), beta-blocker (BB) or angiotensin receptor blocker (ARB) therapy allowed (selection of which dictated by clinical care) if started three months or greater from first dose of IMP without change in dose. Aldosterone receptor antagonists (eg. Spironolactone or eplerenone) allowed if started 12 months or greater from first dose of Medicinal Product (IMP). No changes throughout the study allowed, except in the event of a decline in left ventricular ejection fraction (LVEF) >5% following the baseline CMR as measured by a subsequent CMR at the same center. Should this occur, changes in cardiac medications are allowed on the study.

  10. Any other condition that could interfere with the subject's participation
Terms in these criteria, in plain language(7)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

LVEF (left ventricular ejection fraction)

The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

  14. Change From Baseline in Quality-of-life

    The Pediatric Quality of Life Inventory (PedQL) questionnaire measures core dimensions of health as delineated by the World Health Organization. The core module includes 23 items comprising 14 dimensions. The Gastrointestinal module includes 74 items comprising 14 dimensions. The Neuromuscular module includes 25 items comprising 3 dimensions. Each item in the modules is measured on a 5-point Likert scale of 0-4 with 0 indicating 'never' and 4 indicating 'almost always'. The Likert scores for each subscale are reversed scored and linearly transform to a 0-100 scale with 0=100, 1-75, 2=50, 5=25, and 4=0. A higher score indicates better health-related quality of life. Subscale scores are averaged to generate the total score reported with a range of 0-100. Results are presented as change from baseline at 12 months. The questionnaire was completed by the participant and the parent/guardian of the participant.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 17, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
