- Company commends FDA for swift and comprehensive review of available information
- Shipments to sites of care will resume imminently
- Sarepta and FDA will continue dialogue on next steps in the safety labeling process and risk-mitigation approach for non-ambulatory patients
CAMBRIDGE, Mass., July 28, 2025--(BUSINESS WIRE)--Sarepta Therapeutics, Inc. (NASDAQ:SRPT), the leader in precision genetic medicine for rare diseases, today announced that the U.S. Food and Drug Administration (FDA) notified Sarepta that it may lift its voluntary pause on shipments of ELEVIDYS (delandistrogene moxeparvovec) for ambulatory patients with Duchenne.
Sarepta will resume shipping ELEVIDYS to sites of care for treatment of ambulatory patients with Duchenne imminently.
"Last week, at the suggestion of FDA, Sarepta made the difficult decision to pause shipments of ELEVIDYS to provide the FDA with an opportunity to complete a review of available safety information. We are very pleased that FDA chose to rapidly and comprehensively complete that review and to recommend that we remove our voluntary pause and resume shipment of ELEVIDYS for ambulatory patients. The FDA's swift review evinces a commitment to the Duchenne population, a commitment shared by Sarepta," said Doug Ingram, chief executive officer, Sarepta. "We look forward to working collaboratively with the FDA to complete the safety label update for ELEVIDYS and to discussing the approach to risk-mitigation for non-ambulatory patients, who remain on pause pending the outcome of those discussions."
FDA's review of the safety data in the ambulatory population included the case of an 8-year-old in Brazil whose death was deemed unlikely to be related to treatment with ELEVIDYS by the Brazilian health authorities. FDA's investigation has concluded the death was unrelated to treatment with ELEVIDYS and confirmed that Sarepta can resume shipments.
Patients and physicians can access more information about ELEVIDYS at www.SareptAssist.com or by calling 1-888-727-3782.
ELEVIDYS is the only approved gene therapy for families and children devastated by Duchenne, a rare, progressive and ultimately fatal disease. We remain committed to working closely with the FDA to ensure that all decisions are grounded in science and the best interests of patients, considering the compelling need of these families to access disease-modifying therapy.
About ELEVIDYS (delandistrogene moxeparvovec-rokl)ELEVIDYS (delandistrogene moxeparvovec-rokl) is a single-dose, adeno-associated virus (AAV)-based gene transfer therapy for intravenous infusion designed to address the underlying genetic cause of Duchenne muscular dystrophy – mutations or changes in the DMD gene that result in the lack of dystrophin protein – through the delivery of a transgene that codes for the targeted production of ELEVIDYS micro-dystrophin in skeletal muscle.
ELEVIDYS is indicated for the treatment of Duchenne muscular dystrophy (DMD) in individuals at least 4 years of age.
For patients who are ambulatory and have a confirmed mutation in the DMD gene
For patients who are non-ambulatory and have a confirmed mutation in the DMD gene.
The DMD indication in non-ambulatory patients is approved under accelerated approval based on expression of ELEVIDYS micro-dystrophin in skeletal muscle. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s).
IMPORTANT SAFETY INFORMATION
CONTRAINDICATION: ELEVIDYS is contraindicated in patients with any deletion in exon 8 and/or exon 9 in the DMD gene.
WARNINGS AND PRECAUTIONS:Infusion-related Reactions:
Infusion-related reactions, including hypersensitivity reactions and anaphylaxis, have occurred during or up to several hours following ELEVIDYS administration. Closely monitor patients during administration and for at least 3 hours after the end of infusion. If symptoms of infusion-related reactions occur, slow, or stop the infusion and give appropriate treatment. Once symptoms resolve, the infusion may be restarted at a lower rate.
ELEVIDYS should be administered in a setting where treatment for infusion-related reactions is immediately available.
Discontinue infusion for anaphylaxis.
Acute Serious Liver Injury:
Acute serious liver injury has been observed with ELEVIDYS, and administration may result in elevations of liver enzymes (such as GGT, GLDH, ALT, AST) or total bilirubin, typically seen within 8 weeks.
Patients with preexisting liver impairment, chronic hepatic condition, or acute liver disease (e.g., acute hepatic viral infection) may be at higher risk of acute serious liver injury. Postpone ELEVIDYS administration in patients with acute liver disease until resolved or controlled.
Prior to ELEVIDYS administration, perform liver enzyme test and monitor liver function (clinical exam, GGT, and total bilirubin) weekly for the first 3 months following ELEVIDYS infusion. Continue monitoring if clinically indicated, until results are unremarkable (normal clinical exam, GGT, and total bilirubin levels return to near baseline levels).
Systemic corticosteroid treatment is recommended for patients before and after ELEVIDYS infusion. Adjust corticosteroid regimen when indicated. If acute serious liver injury is suspected, consultation with a specialist is recommended.
Immune-mediated Myositis:
In clinical trials, immune-mediated myositis has been observed approximately 1 month following ELEVIDYS infusion in patients with deletion mutations involving exon 8 and/or exon 9 in the DMD gene. Symptoms of severe muscle weakness, including dysphagia, dyspnea, and hypophonia, were observed.
Limited data are available for ELEVIDYS treatment in patients with mutations in the DMD gene in exons 1 to 17 and/or exons 59 to 71. Patients with deletions in these regions may be at risk for a severe immune-mediated myositis reaction.
Advise patients to contact a physician immediately if they experience any unexplained increased muscle pain, tenderness, or weakness, including dysphagia, dyspnea, or hypophonia, as these may be symptoms of myositis. Consider additional immunomodulatory treatment (immunosuppressants [e.g., calcineurin-inhibitor] in addition to corticosteroids) based on patient's clinical presentation and medical history if these symptoms occur.
Myocarditis:
Acute serious myocarditis and troponin-I elevations have been observed following ELEVIDYS infusion in clinical trials.
If a patient experiences myocarditis, those with pre-existing left ventricle ejection fraction (LVEF) impairment may be at higher risk of adverse outcomes. Monitor troponin-I before ELEVIDYS infusion and weekly for the first month following infusion and continue monitoring if clinically indicated. More frequent monitoring may be warranted in the presence of cardiac symptoms, such as chest pain or shortness of breath.
Advise patients to contact a physician immediately if they experience cardiac symptoms.
Preexisting Immunity against AAVrh74:
In AAV-vector based gene therapies, preexisting anti-AAV antibodies may impede transgene expression at desired therapeutic levels. Following treatment with ELEVIDYS, all patients developed anti-AAVrh74 antibodies.
Perform baseline testing for presence of anti-AAVrh74 total binding antibodies prior to ELEVIDYS administration.
ELEVIDYS administration is not recommended in patients with elevated anti-AAVrh74 total binding antibody titers greater than or equal to 1:400.
Adverse Reactions:
The most common adverse reactions (incidence ≥5%) reported in clinical studies were vomiting, nausea, liver injury, pyrexia, and thrombocytopenia.
