While glucocorticoids are used as first-line therapy for Duchenne muscular dystrophy (DMD), these agents are associated with several adverse events, including accelerated bone loss and muscle atrophy. As a result, prolonged glucocorticoid treatment is one of the primary contributors to the high fracture rate in patients with DMD.

“We’re going to battle,” PTC Therapeutics Inc. CEO Matthew Klein said, responding to a surprise negative opinion from the EMA’s Committee for Medicinal Products for Human Use on converting the conditional marketing authorization to full status for Translarna (ataluren) in the treatment of nonsense mutation Duchenne muscular dystrophy. The opinion applies to the renewal of the existing conditional authorization, too.

Biomarin Pharmaceutical Inc. has reported progress across its research and development portfolio, including early-stage product candidates.

Precision Biosciences Inc. uses its proprietary Arcus platform to develop in vivo gene editing therapies and has outlined new data from its wholly owned and partnered pipeline.

Satellos Bioscience Inc. has received orphan drug designation and rare pediatric disease designation from the FDA for SAT-3153 for the potential treatment of Duchenne muscular dystrophy (DMD). The first-in-class oral small-molecule therapeutic is designed to restore the innate muscle regeneration process independent of dystrophin and regardless of exon mutation status.

Duchenne muscular dystrophy (DMD) is an X-linked genetic disorder affecting roughly 1 in 3,500 males. DMD is due to mutations in the dystrophin gene, which encodes for an exceptionally large 427 kD protein. DMD is characterized by repeated degeneration and regeneration of muscle fibers, but ultimately replacement of muscle with fibrotic and adipose tissue. Despite advances in gene therapy and improvements in quality of life, most patients still die by 30 years of age due to cardiopulmonary failure.
