Catabasis Pharmaceuticals Announces the Phase 3 PolarisDMD Trial of Edasalonexent in Duchenne Muscular Dystrophy has Exceeded Target Enrollment - Seite 2

About Phase 3 PolarisDMD Trial
The global Phase 3 PolarisDMD trial is a one-year, randomized, double-blind, placebo-controlled trial evaluating the efficacy and safety of edasalonexent in patients with DMD. The trial enrolled patients ages 4 to 7 (up to 8^th birthday) regardless of mutation type who had not been on steroids for at least 6 months. Boys on a stable dose of eteplirsen were also eligible to enroll. The primary efficacy endpoint is change in the North Star Ambulatory Assessment score after 12 months of treatment with edasalonexent compared to placebo. Key secondary endpoints include the age-appropriate timed function tests: time to stand, 4-stair climb and 10-meter walk/run. Assessments of growth, cardiac and bone health are also included as important potential areas of differentiation. For each boy that receives placebo, two boys are receiving 100 mg/kg/day of edasalonexent and after 12 months, all boys are expected to receive edasalonexent in the open-label extension study GalaxyDMD. The PolarisDMD trial design was informed by discussions with regulators as well as input from treating physicians, patient organizations and families of boys affected by Duchenne. Top-line results from the Phase 3 PolarisDMD trial are expected in the fourth quarter of 2020. More information about the Phase 3 PolarisDMD clinical trial is available on clinicaltrials.gov.
