People with myotonic dystrophy (DM) use more healthcare resources and face higher associated costs than patients without the disease, according to a U.S. study that analyzed a large database of insurance claims. After diagnosis, DM patients are more likely to be hospitalized and visit an emergency department, researchers found.

The progression of myotonic dystrophy type 1, known as DM1, differs according to sex and age at symptom onset, according to the findings of a four-year study, but the researchers nonetheless reported “notable variability” with patients’ general decline. The study, by researchers in the Netherlands, focused on changes over…

Losmapimod, an investigational medication from Fulcrum Therapeutics, failed to significantly outperform a placebo at improving upper limb function and other clinical measures in people with facioscapulohumeral muscular dystrophy (FSHD), according to top-line data from the REACH Phase 3 trial. Participants given losmapimod did see improvements over 48…

The U.S. Food and Drug Administration (FDA) has granted orphan drug status to RAG-18, being developed as a potential treatment for both Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD).
