A new dominant-negative tumor necrosis factor (DN-TNF) treatment reduced muscle damage and promoted muscle regeneration in a mouse model of Duchenne muscular dystrophy (DMD), according to INmune Bio. The research is part of a collaboration between INmune and Armando Villalta, PhD, a professor at the University California, Irvine…

After 18 months, treatment with the experimental cell therapy CAP-1002 continues to show beneficial effects on upper limb function in people with Duchenne muscular dystrophy (DMD), according to new data from the open-label extension phase of the HOPE-2 study. The new trial data also suggests a consistent safety…

Wave Life Sciences‘ experimental exon-skipping therapy WVE-N531 appears to be working as expected, according to early data from a small clinical trial of the therapy in a first group of three boys with Duchenne muscular dystrophy (DMD). “These data provide early evidence that WVE-N531 is … leading to…

The U.S. Food and Drug Administration (FDA) has given priority review Sarepta Therapeutics‘ application seeking accelerated approval of SRP-9001 (delandistrogene moxeparvovec), the company’s experimental gene therapy for Duchenne muscular dystrophy (DMD) in patients who can walk. An FDA decision is expected on or before May 29, 2023. “We are delighted…

PGN-EDO53, an experimental therapy designed to treat Duchenne muscular dystrophy (DMD) in patients amenable to exon 53 skipping, showed promising effects in preclinical studies, the therapy’s developer PepGen announced. The company also announced promising results from cell experiments for two other investigational exon-skipping therapies, PGN-EDO45 and PGN-EDO44.

Sarepta Therapeutics plans to begin a clinical trial to test the antibody-cleaving therapy imlifidase as a pre-treatment for SRP-9001 (delandistrogene moxeparvovec) — its experimental gene therapy for Duchenne muscular dystrophy (DMD) — in patients with pre-existing antibodies against the gene therapy’s viral carrier. Preclinical work conducted by…

Santhera and ReveraGen have completed their rolling application asking the U.S. Food and Drug Administration (FDA) to approve the dissociative corticosteroid vamorolone to treat Duchenne muscular dystrophy (DMD). Rolling applications allow companies to submit individual sections of the application as soon as they are completed, rather than waiting…

Treatment with Viltepso (viltolarsen) helps preserve motor function in boys with Duchenne muscular dystrophy (DMD) amenable to exon 53 skipping, according to four-year data from an open-label extension study. “These data represent the longest clinical experience of an exon 53 skipping therapy for the treatment of Duchenne…

The U.K.’s National Institute for Health and Care Excellence (NICE) has published new draft guidance that does not recommend Translarna (ataluren) be covered to treat Duchenne muscular dystrophy (DMD) caused by nonsense mutations. According to NICE, although there’s evidence Translarna can benefit people with DMD, it’s not worth…

Sarepta Therapeutics has submitted an application to the U.S. Food and Drug Administration (FDA) asking the agency to grant accelerated approval to the gene therapy SRP-9001 (delandistrogene moxeparvovec) as a treatment for Duchenne muscular dystrophy (DMD) in patients who are able to walk. “Every hour of every…
