Pfizer has discontinued development of fordadistrogene movaparvovec, its investigational gene therapy for Duchenne muscular dystrophy (DMD), after recent Phase 3 trial data indicated a failure to improve motor function in boys with the neuromuscular disease. Patients who have already received the gene therapy in the CIFFREO…

A pair of identical twins with myotonic dystrophy type 1 (DM1) were found to have different deficits in social cognition that corresponded with differing patterns of brain tissue loss on MRI scans, a case report shows. Researchers believe the findings highlight that, while genetic factors can contribute to brain development,…

DYNE-101 and DYNE-251, Dyne Therapeutics’ investigational therapies for forms of muscular dystrophy, continue to work as intended and may lead to functional improvements for patients, according to new clinical trial data. These findings come from ongoing Phase 1/2 studies, which may still be recruiting. DELIVER (NCT05524883), launched…

Findings from a Phase 2 trial testing losmapimod in adults with facioscapulohumeral muscular dystrophy (FSHD) have offered new insights into the best outcome measures for future clinical trials, according to final published data from the clinical study, which wrapped up in 2021. The  Fulcrum Therapeutics treatment, as…

Dosing has been paused in a Phase 3 trial testing fordadistrogene movaparvovec in children with Duchenne muscular dystrophy (DMD) following the sudden death of a boy who had been previously treated with the gene therapy, its developer Pfizer announced in a letter to the community. Pfizer indicated…

Agamree (vamorolone) is now available for Duchenne muscular dystrophy (DMD) patients, ages 2 and older, in the U.S., where it will be dispensed through a specialty pharmacy network. The U.S. Food and Drug Administration (FDA) approved the next-generation steroid, expected to be more tolerable than standard…

The investigational cell therapy CAP-1002 has continued to slow declines in upper limb and heart function among boys and young men with Duchenne muscular dystrophy (DMD), according to two-year results from the HOPE-2 open label extension (OLE) study. The findings were presented at the recent 2024 Muscular Dystrophy…

DYNE-251 and DYNE-101, Dyne Therapeutics’ investigational therapies for forms of muscular dystrophy, appear safe and are showing signs of preliminary efficacy in Phase 1/2 clinical trials. These proof-of-concept data, announced by Dyne in January, were discussed in two oral presentations at the recent 2024 Muscular Dystrophy…

Among ambulatory boys with Duchenne muscular dystrophy (DMD), a one-time treatment with investigational gene therapy fordadistrogene movaparvovec has helped preserve functions and increase muscle volume for three years, especially in the youngest patients. That’s according to updated analyses from a Phase 1b trial (NCT03362502), in which the…

HuidaGene Therapeutics’ investigational gene-editing therapy, called HG302, for Duchenne muscular dystrophy (DMD) has been granted a rare pediatric drug designation by the U.S. Food and Drug Administration (FDA). This status is intended to incentivize companies to develop treatments for rare and serious or life-threatening diseases affecting people under…
