FDA grants AOC 1001 Fast Track Designation to treat Myotonic Dystrophy Type 1 (DM1).
AOC 1001, an investigational treatment for Myotonic Dystrophy Type 1 (DM1), a late-developing muscle disorder, has received fast track designation from the U.S. Food and Drug Administration (FDA). The FDA’s fast track program’s overall goal is to expedite the review of therapies that have the potential to improve the care of people with serious illnesses. Avidity Biosciences, the company behind AOC 1001, will be able to communicate with the FDA more frequently due to the designation.

Myotonic dystrophy type 1 (DM1) is the most common form of muscular dystrophy in adults. DM1 is a dominant disorder characterized by multisystemic clinical features affecting skeletal muscle, heart, and the nervous and endocrine systems.
- The prevalence varies by region and is most common in individuals of European descent. According to Thelansis disease modeling data, literature reviews, surveys, and registry analyses combined prevalence reported as 1 in 8,000 (12.5 per 100,000).
- DM1 is caused by expansion of a CTG repeat in the 3′ noncoding region of the DMPK gene on chromosome 19q13.3, which codes for the myotonic dystrophy protein kinase.
- Normal individuals have between 5 and 37 repeats, but symptomatic patients typically have > 50 repetitions.
- DM1 is categorized into four subtypes: congenital, childhood, classic, and minimal / late-onset.
