Arrakis Therapeutics’ investigational RNA-targeted small molecule (rSM) therapies were found to work as intended in preclinical studies and eased symptoms in a mouse model of myotonic dystrophy type 1 (DM1). The company presented the findings at the Cell Symposia: Chemical Biology in Drugging the Undrugged conference, held earlier…

Sarepta Therapeutics is acquiring from Arrowhead Pharmaceuticals the exclusive global rights to develop ARO-DUX4 and ARO-DM1, two RNA interference (RNAi) therapeutic candidates in Phase 1/2 clinical testing, each for one type of muscular dystrophy. ARO-DUX4 is being tested for facioscapulohumeral muscular dystrophy (FSHD) and ARO-DM1 for…

A woman who developed heart failure due to Duchenne muscular dystrophy (DMD) was diagnosed and treated before she got pregnant, which led to a healthy outcome for her and her baby girl, according to researchers in Japan. The woman’s case was reported in “Successful Pregnancy Outcome With Preconception…

GNT0004, an experimental gene therapy for Duchenne muscular dystrophy (DMD), appears to be working as intended in the initial parts of a multiphase clinical trial, with benefits including stable or improved motor function. That’s according to data presented by Genethon, the therapy’s developer, at the ASGCT Breakthroughs in…

Regenxbio has initiated the pivotal phase of a clinical trial testing its experimental gene therapy RGX-202 in boys with Duchenne muscular dystrophy (DMD). If the results are positive, they could support the therapy’s accelerated approval by the U.S. Food and Drug Administration (FDA). Regenxbio has also announced…

A new technology called StitchR effectively restored the production of large muscle proteins dystrophin and dysferlin in mouse models of Duchenne muscular dystrophy (DMD) and limb-girdle muscular dystrophy (LGMD), according to a study. The results have potential implications for gene therapies. The technology works by delivering two halves…

The U.S. Food and Drug Administration (FDA) has given Atamyo Therapeutics the go-ahead to start a Phase 1b clinical trial to test ATA-200 — the company’s gene therapy candidate for limb-girdle muscular dystrophy type 2C/R5, or LGMD2C/R5 — in children with this form of LGMD in the U.S.

Despite positive trial data, Sarepta Therapeutics has decided to stop the clinical development of SRP-5051 (vesleteplirsen), an exon 51-skipping therapy for some people with Duchenne muscular dystrophy (DMD). While increases in dystrophin levels seen with the exon-skipping treatment were encouraging, according to the company, concerns over the…

Specific genetic mutations in Duchenne muscular dystrophy (DMD) influence how long patients retain the ability to walk, even when treated with corticosteroids, according to a study that highlights the importance of genetic testing in predicting disease progression. These findings are relevant because understanding how fast the disease progresses based on…

A new patient group is being enrolled in a Phase 1/2 trial of delpacibart braxlosiran (del-brax), an experimental and potentially disease-modifying therapy for facioscapulohumeral muscular dystrophy (FSHD), its developer, Avidity Biosciences, announced. The additional trial cohort, which is expected to be recruited in full early next year,…
