The Committee for Medicinal Products for Human Use (CHMP) — part of the European Medicines Agency — again maintained its recommendation not to renew conditional marketing authorization for Translarna (ataluren), a treatment for Duchenne muscular dystrophy (DMD) caused by nonsense mutations. The European Commission, which has final say…

Treatment with antimiRs, an RNA-based therapy approach, was able to correct molecular defects in a cell model of myotonic dystrophy type 1 (DM1) — a form of muscular dystrophy — according to the results of a new study. The researchers called their work “a significant step forward,” and noted that…

The U.S. Food and Drug Administration (FDA) has granted rare pediatric disease designation to SAT-3247, an oral treatment candidate for Duchenne muscular dystrophy (DMD) that ultimately aims to slow the progression of the genetic condition. The FDA awards this status to investigational medicines that are designed to treat serious,…

Duvyzat (givinostat), a newly approved treatment for Duchenne muscular dystrophy (DMD), is now available in the U.S., according to an announcement from ITF Therapeutics, which will be selling the therapy. “Following the FDA [Food and Drug Administration] approval of Duvyzat, our team has been focused on making…

Most children with Duchenne muscular dystrophy (DMD) start experiencing notable issues with arm function and breathing ability before they lose the ability to walk, a new study reports. The findings have major implications for clinical trials testing treatments that aim to boost arm and/or lung function in DMD. Traditionally,…
