New Jersey-based PTC Therapeutics has begun submitting a rolling new drug application (NDA) to the U.S. Food and Drug Administration (FDA) for the approval of its experimental drug for the treatment of Duchenne muscular dystrophy (DMD) caused by specific flaws (mutations) in the dystrophin gene.

The investigational compound is designed to raise levels of the SMN protein, a lack of which is the underlying cause of spinal muscular atrophy (SMA)

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.

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.

Trials of the experimental muscular dystrophy drug ataluren showed that the drug was generally well-tolerated and slowed the rate of decline in walking ability, compared to the placebo group. After consulting with regulatory agencies in Europe and the United States, biopharmaceutical company PTC Therapeutics has decided to move ahead with a global, phase 3 confirmatory study of ataluren.
