Enrollment is now ongoing in a first-in-human trial testing EPI-321, an epigenetic therapy designed to address the root cause of facioscapulohumeral muscular dystrophy (FSHD), a disease type in which symptoms like muscle weakness typically become apparent by adulthood. The Phase 1/2 clinical trial (NCT06907875) is expected to enroll…

Note: This story was updated July 30, 2025, to include data from part two of the EMBARK trial. Sarepta Therapeutics will soon resume shipping Elevidys (delandistrogene moxeparvovec-rokl) for ambulatory Duchenne muscular dystrophy (DMD) patients, following a review of safety data by the U.S. Food and Drug Administration (FDA),…

Sarepta Therapeutics is voluntarily halting all shipments of Elevidys (delandistrogene moxeparvovec-rokl) in the U.S. after a request from the U.S. Food and Drug Administration (FDA). The company had initially refused to pause the shipments of its gene therapy for Duchenne muscular dystrophy (DMD) for individuals with DMD who…

The U.S. Food and Drug Administration (FDA) has granted rare pediatric disease designation to PBGENE-DMD, an experimental gene-editing therapy for Duchenne muscular dystrophy (DMD) that’s being developed by Precision Biosciences. The designation provides companies with extra incentives to develop experimental therapies to treat rare diseases that mainly affect…

The U.S. Food and Drug Administration (FDA) is due to convene an advisory committee meeting next month to review the data on deramiocel, an experimental cell therapy up for approval to treat heart disease in people with Duchenne muscular dystrophy (DMD). The FDA has informed Capricor Therapeutics…

A second person with Duchenne muscular dystrophy (DMD) has died of acute liver failure after being treated with the one-time gene therapy Elevidys (delandistrogene moxeparvovec-rokl). A first death was announced in March and both occurred in people with DMD who were no longer able to walk. Following…

The U.S. Food and Drug Administration (FDA) granted platform technology designation to the viral vector used in SRP-9003, an investigational gene therapy for limb-girdle muscular dystrophy type 2E (LGMD2E). “This is one of the first programs to receive platform technology designation and an important recognition by FDA of…

Following lackluster data from a Phase 2 clinical trial, Pepgen will discontinue developing PGN-ED051, its experimental exon 51-skipping therapy for Duchenne muscular dystrophy (DMD). The company said it will wind down all DMD-related research and development activities, focusing instead on an investigational therapy for myotonic dystrophy type…

CureDuchenne is investing $1 million in Entos Pharmaceuticals to support the development of a new gene therapy for Duchenne muscular dystrophy (DMD) that aims to overcome the limitations of existing gene therapies. “This investment underscores our continued use of venture philanthropy to catalyze progress [toward] transformative treatments…

Note: This story was updated May 19, 2025, to clarify the requirements needed for Elevidys to transition to full approval.
