Clinical Trial Alert: PTC Therapeutics Seeks Participants for a Phase 3 DMD Study

Researchers at PTC Therapeutics are looking for participants with Duchenne muscular dystrophy (DMD) to participate in a Phase 3 study. The goal of the study is to characterize the long-term effects of Translarna (ataluren). The drug is believed to promote the formation of full-length and functional dystrophin protein in boys with a nonsense mutation (which means no dystrophin protein is produced).

The study may determine whether treatment with ataluren is associated with stabilized or slowed disease progression as measured by a change in six-minute walk distance (6MWD) over 72 weeks.

Participants will be randomized to receive either placebo or ataluren, with an option to receive the study drug during an open-label extension period. The trial will consist of approximately 11 clinic visits that will include a series of vital and functional tests.

To be eligible to participate, individuals must be:

• Male, older than 5 years
• Genetically diagnosed with a nonsense point mutation in the dystrophin gene
• Receiving systemic corticosteroids for a minimum of 12 months (with no significant change in dosage or dosing regimen for a minimum of three months) prior to the start of the study
• Able to walk 150 meters or more within six minutes (6MWD≥150 meters)
• Able to perform timed function tests within 30 seconds

Travel support may be available.
