BOSTON–(BUSINESS WIRE)–Catabasis Pharmaceuticals, Inc. (NASDAQ:CATB), a clinical-stage biopharmaceutical company, today reported financial results for the third quarter ended September 30, 2019 and reviewed recent business progress.

“We have made significant clinical progress with our lead program edasalonexent, a potential foundational therapy for the treatment of Duchenne muscular dystrophy. We are excited that enrollment is complete and target enrollment was exceeded for our Phase 3 PolarisDMD trial of edasalonexent. We very much appreciate the strong interest from physicians and the Duchenne community that propelled trial enrollment. We look forward to reporting top-line results in the fourth quarter of next year,” said Jill C. Milne, Ph.D., Chief Executive Officer of Catabasis. “In preparation for the potential commercialization of edasalonexent, we strengthened our executive team with the addition of Andrew Komjathy as Chief Commercial Officer.”

Recent and Upcoming Corporate Highlights

• Phase 3 PolarisDMD of edasalonexent in Duchenne muscular dystrophy (DMD)
  • Trial enrollment is complete and has exceeded the enrollment target with 131 boys enrolled. Patients are enrolled across all 8 countries where the trial is active.
  • Top-line results from the Phase 3 PolarisDMD trial are expected in Q4 of 2020, and the trial is intended to support an application for commercial registration of edasalonexent in 2021.
• Clinical findings supporting edasalonexent as a potential foundational therapy for the treatment of DMD from the Phase 2 MoveDMD trial and open-label extension were presented at the 24^th International Annual Congress of the World Muscle Society by Dr. Richard Finkel, M.D., Chief, Division of Neurology, Department of Pediatrics at Nemours Children’s Health System, and Principal Investigator for the MoveDMD and Phase 3 PolarisDMD trials of edasalonexent in DMD. Edasalonexent slowed disease progression compared to the off-treatment control period and was well tolerated through 60 cumulative years of patient exposure in boys affected by DMD.
• Catabasis named Andrew A. Komjathy as its Chief Commercial Officer, adding deep rare disease commercial experience to the executive team.
• Catabasis and the Jain Foundation announced a preclinical research collaboration to study edasalonexent in Dysferlinopathy, which includes Limb-girdle muscular dystrophy type 2B and Miyoshi myopathy. Edasalonexent has the potential to benefit patients with other diseases beyond DMD, such as Dysferlinopathy.

About Edasalonexent (CAT-1004)

Edasalonexent (CAT-1004) is an investigational oral small molecule designed to inhibit NF-kB that is being developed as a potential foundational therapy for all patients affected by DMD, regardless of their underlying mutation. In DMD the loss of dystrophin leads to chronic activation of NF-kB, which is a key driver of skeletal and cardiac muscle disease progression. Our ongoing global Phase 3 PolarisDMD trial is evaluating the efficacy and safety of edasalonexent for registration purposes. Edasalonexent is also being dosed in the open-label extension trial GalaxyDMD. In our MoveDMD Phase 2 trial and open-label extension, we observed that edasalonexent preserved muscle function and substantially slowed disease progression compared to rates of change in a control period, and significantly improved biomarkers of muscle health and inflammation. The FDA has granted orphan drug, fast track, and rare pediatric disease designations and the European Commission has granted orphan medicinal product designation to edasalonexent for the treatment of DMD.
