Multiple factors affect CK-MM blood test for DMD

Various factors influenced the results of the creatine kinase-MM (CK-MM) blood test used to screen infants for Duchenne muscular dystrophy (DMD), according to a large study. Factors that affected CK-MM levels included age at blood sample collection, gestational age, birth weight, sex, ethnicity, and seasonal temperature, data showed. Newborn…

New blood biomarkers better reflect motor performance in Becker MD

In people with Becker muscular dystrophy (BMD), both an elevated creatine-to-creatinine ratio and lower myostatin muscle protein levels in the bloodstream are associated with worse motor performance, a study reported. These two potential biomarkers predicted current functional abilities when combined with age but not disease progression over four years. Both…

Microdystrophin gene therapy can prevent heart damage in DMD mice

Microdystrophin gene therapy effectively maintained long-term heart function in a mouse model of severe Duchenne muscular dystrophy (DMD), a study has found. The treatment prevented scar formation and inflammation in heart tissue, and maintained normal heart function over 18 months. These findings support the ongoing clinical trials evaluating…

FDA grants orphan drug, rare pediatric status for DYNE-251

DYNE-251, an investigational therapy for Duchenne muscular dystrophy (DMD), has received orphan drug and rare pediatric disease designations from the U.S. Food and Drug Administration (FDA). Orphan drug status is meant to support the development of therapies for rare conditions affecting less than 200,000 people in the U.S. It…

Nanoparticles Help Deliver Treatment in DM1 Cell Study

The approved antiparasitic medicine pentamidine, loaded into biocompatible and biodegradable nanoparticles, successfully eased signs of myotonic dystrophy type 1 (DM1) in cell-based models, a study shows. The researchers noted that these findings show the potential of nanoparticles to deliver therapeutic agents to treat muscle cells in people with DM1…

Bone Biomarkers Maintained With Vamorolone Over Prednisone: Study

Vamorolone, an investigational therapy for Duchenne muscular dystrophy (DMD), maintained biomarkers of bone formation and turnover compared to prednisone, according to the now published details of the VISION-DMD study. Standard anti-inflammatory corticosteroids, such as prednisone, have been shown to stunt growth with long-term use. Vamorolone is a…

Cognitive Decline Seen in Myotonic Dystrophy Type 1 Children: Study

Children with myotonic dystrophy type 1 (DM1) showed a decline in cognitive function over two years, with frequent impairment in visuospatial skills and attention, a small study suggested. The data indicate cognitive, neuropsychological, emotional, and behavioral assessments should be administered to children with DM1 periodically during development, the researchers…
