Compounds designed to alter genetic instructions for dystrophin, increase production of utrophin, or prevent scar tissue formation in muscle are moving through the development pipeline
Drug development for Duchenne muscular dystrophy (DMD) is progressing on several fronts. Here are some updates as of early November 2014.
PTC is moving forward with ataluren
The European Medicines Agency expressed a 'positive opinion' on conditional approval for ataluren (Translarna) to treat Duchenne MD; a decision is expected within three months
The experimental Duchenne muscular dystrophy (DMD) drug ataluren (which has been given the brand name Translarna) has received encouragement from the European Medicines Agency (EMA) for conditional approval in European Union countries.
Ataluren (PTC124) for Duchenne-Becker MD related to premature stop codons did not receive approval in Europe prior to completion of an ongoing phase 3 trial
The experimental drug ataluren, in development for Duchenne muscular dystrophy (DMD) or Becker muscular dystrophy (BMD) caused by specific mutations in the gene for the dystrophin protein, will not receive conditional approval at this time from the European Medicines Agency (EMA). Ataluren's developer is requesting that the EMA re-examine the data.
An increase in dystrophin was seen in a foot muscle in 61 percent of boys with nonsense-mutation DMD treated with ataluren in an MDA-supported study
An increase in levels of the dystrophin protein was seen after treatment with the experimental drug ataluren (originally called PTC124) in an MDA-supported, phase 2a, open-label trial of 38 boys with Duchenne muscular dystrophy (DMD) caused by a specific type of mutation in the dystrophin gene.
PTC Therapeutics' phase 3 trial of its experimental drug ataluren remains open to boys with Duchenne or Becker MD caused by premature stop codon mutations
PTC Therapeutics, a South Plainfield, N.J., biopharmaceutical company, wants to remind families affected by Duchenne muscular dystrophy (DMD) or Becker muscular dystrophy (BMD) caused by specific genetic mutations that its phase 3 trial of
Although the experimental Duchenne-Becker MD drug ataluren appeared to benefit walking ability in a clinical trial, some researchers question whether it works via stop codon read-through
It's been widely accepted that the mechanism by which the experimental drug ataluren appears to benefit walking ability in Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD) is that it causes "read-through" of premature stop codons — genetic instructions that cause cells to stop making a protein before the process is complete.
PTC Therapeutics' large-scale multinational trial of ataluren for nonsense-mutation Duchenne or Becker MD has opened its first site in Cincinnati, Ohio
Update (Oct. 31, 2013): This story has been updated to reflect that several trial sites are open to new participants.
A large-scale, multinational, phase 3 trial of the experimental drug ataluren has opened at several sites.
