Muscular Dystrophy

The executive vice president and chief research officer of the Muscular Dystrophy Association shared her reaction to the recent FDA approval of givinostat for Duchenne muscular dystrophy.

Branded as Duvyzat, givinostat is the first nonsteroidal drug approved to treat patients with all genetic variants of DMD.

The chief executive officer at Elixirgen Therapeutics provided commentary on the promise of the Bobcat mRNA, and the mechanism of action for mRNA-like therapies to treat Duchenne muscular dystrophy.

A recent study presented at MDA 2024 highlighted the evolving respiratory patterns in pediatric patients with Duchenne muscular dystrophy, offering crucial insights for effective respiratory management in this patient population.

A recent analysis of data from the US National Registry presented at MDA 2024 revealed gender disparities in pediatric-onset facioscapulohumeral muscular dystrophy, with girls experiencing more severe outcomes.

In a recent phase 2 trial analysis of viltolarsen presented at MDA 2024, findings showed improvement in forced vital capacity compared with standard care in patients with Duchenne muscular dystrophy.

A new meta analysis of 3 studies presented at MDA 2024 revealed that ataluren significantly slowed the decline in muscle function for patients with nonsense mutation Duchenne muscular dystrophy.

A recent post hoc analysis of the phase 3 EPIDYS trial presented at MDA 2024 revealed significant positive outcomes with givinostat, a histone deacetylase inhibitor, among patients with Duchenne muscular dystrophy.

Over a 52-week treatment period, treatment with SRP-9001 resulted in improvements in secondary outcomes of time to rise, micro-dystrophin expression, and 10-meter walk/run.

Patients with Duchenne muscular dystrophy between ages of 6 and 24 months old demonstrated a similar safety profile on eteplirsen than those between 24 and 48 months of age.

In a real-world study, eterplirsen was safe for patients with Duchenne muscular dystrophy, with sustained or improved status in function.

Tadalafil shows potential in addressing microvascular impairment in Duchenne muscular dystrophy, with post-contractile MRI as a screening tool.

In honor of Rare Disease Day, the vice president of public policy and advocacy at the Muscular Dystrophy Association shared his perspective of advocacy and policy progress in the realm of rare neuromuscular diseases. [WATCH TIME: 6 minutes]

PepGen has begun its phase 2 CONNECT1-EDO51 trial, dosing the first patient with PGN-EDO51, an agent for Duchenne muscular dystrophy amendable to an exon 51 skipping.

The FDA has accepted Sarepta Therapeutics' efficacy supplement for gene therapy SRP-9001, granting it a priority review for the treatment of Duchenne muscular dystrophy, with a decision expected by June 21, 2024.

The efficacy of vamorolone at a dose of 6 mg/kg/d was maintained over 48 weeks of treatment for all 5 motor outcomes.

The postdoctoral research fellow at Brigham and Women’s Hospital and Harvard Medical School discussed some of the issues with ensuring timely care access to approved therapies for patients with Duchenne muscular dystrophy. [WATCH TIME: 3 minutes]

Ahead of the 2024 MDA Conference, the medical advisor and care center director at Muscular Dystrophy Association talked about the track sessions he will be cochairing at the meeting. [WATCH TIME: 5 minutes]

The postdoctoral research fellow at Brigham and Women’s Hospital and Harvard Medical School provided answers to a recently published study highlighting the burden of care and infrequent use of novel exon-skipping drugs for Duchenne in clinical settings. [WATCH TIME: 3 minutes]

Despite conditional approval in Europe since 2014, ataluren's authorization has faced rejections and is still investigational in the US.

Despite initial enthusiasm, novel treatments for Duchenne muscular dystrophy face discontinuation challenges and lack long-term clinical efficacy data.

Over a 28-week treatment period, the investigational agent demonstrated significantly greater increase in dystrophin expression and exon skipping than previously approved eteplirsen, Sarepta’s first therapy for Duchenne muscular dystrophy.

After 6 months of treatment, once every 4-week administration of DYNE-251 reached levels of dystrophin expression, exon skipping, and percent dystrophin positive fibers that exceeded levels reported in a previous trial of eteplirsen, considered the standard of care.

Overall, investigators observed DMPK knockdown, consistent splicing correction, and meaningful function improvement in myotonia while on DYNE-101.

Assessments on PGN-EDODM1's safety, transcript splicing correction, and clinical outcome measures data at the 5 mg/kg dose level from trial is expected this year.

Steve Hughes, MD, chief medical officer at Avidity Biosciences, provided commentary on recently announced positive topline data for AOC 1044, an investigational agent for Duchenne muscular dystrophy.

AOC 1044 was well-tolerated in healthy volunteers, delivering dose-dependent increases in PMO concentrations in skeletal muscle following administration.

The positive data report could potentially build on phase 2 study of Duchenne muscular dystrophy in which CAP-1002 met its primary end point.

Pitolisant demonstrated a dose-dependent improvement in excessive daytime sleepiness and fatigue, with a safety profile that was consistent with previous studies. Additional data to be shared in early 2024.
