Top-Line Results Expected in Q4 2020 from Fully Enrolled Edasalonexent Global Phase 3 PolarisDMD Trial in Duchenne Muscular Dystrophy

BOSTON--(BUSINESS WIRE)--May 12, 2020-- Catabasis Pharmaceuticals, Inc. (NASDAQ:CATB), a clinical-stage biopharmaceutical company, today reported financial results for the first quarter ended March 31, 2020 and reviewed recent business progress.

“Our fully enrolled Phase 3 PolarisDMD trial for edasalonexent in Duchenne is progressing well and we are continuing to prepare for top-line Phase 3 results in the fourth quarter of this year and a subsequent NDA filing in 2021. We have initial commercialization and supply chain preparations underway and recently strengthened our financial position,” said Jill C. Milne, Ph.D., Chief Executive Officer of Catabasis. “In the current environment, our priorities are focused on the safety of patients as well as maintaining study integrity. Advantages of our Phase 3 trial include that enrollment was completed last year, clinical trial site visits are only every three months, and that patients take the oral study drug at home. Together with our clinical trial sites and consistent with recent regulatory guidance, we have developed contingency plans that we are implementing as needed to enable the continued conduct of the Phase 3 trial as well as the open-label extension GalaxyDMD trial.”

Recent and Upcoming Corporate Highlights

• The fully enrolled Phase 3 PolarisDMD trial of edasalonexent in Duchenne muscular dystrophy (DMD) is progressing with top-line results expected in Q4 2020.
  • Patient enrollment was completed in 2019 with 131 boys enrolled across 8 countries.
  • The Phase 3 PolarisDMD trial is intended to support a new drug application (NDA) for commercial registration of edasalonexent in 2021.
  • Contingency plans are in place to enable the continued conduct of our Phase 3 PolarisDMD and GalaxyDMD clinical trials. These plans include the delivery of study drug to patients’ homes, increased flexibility in the timing of patient visits, and use of telehealth for remote visits to monitor safety and assess patients where in-person visits are not available.
• The open-label extension GalaxyDMD trial continues to enroll boys who have completed treatment in the Phase 3 PolarisDMD trial. Their eligible siblings up to age 12 have the option to enroll as well.
• Catabasis closed a $26.5 million underwritten public offering in February 2020. The proceeds will be used for clinical trial and other research and development activities; initial commercialization preparations; and for working capital and other general corporate purposes. Based on the Company’s current operating plan, Catabasis expects that it has sufficient cash to fund operations through a potential NDA filing and into Q3 2021.
• Catabasis plans to commercialize edasalonexent in the US and we are evaluating our commercialization strategy outside of the US. We are encouraged by the favorable feedback we have received from healthcare providers and payors on the potential profile for edasalonexent and the meaningful role it could play as a foundational therapy for all patients with DMD, regardless of mutation.
• Clinical findings supporting edasalonexent treatment in young boys being associated with age-normative growth and normal adrenal function from the Phase 2 MoveDMD trial and open-label extension were presented at the Muscular Dystrophy Association Virtual Clinical Trials Session by Dr. Erika Finanger, M.D., Division of Neurology at Oregon Health and Science University and a Principal Investigator for the Phase 2 MoveDMD, Phase 3 PolarisDMD, and open-label extension GalaxyDMD trials of edasalonexent in DMD.
• Catabasis and Duchenne UK entered into a partnership to evaluate edasalonexent in a Phase 2 trial in non-ambulatory DMD patients. Duchenne UK granted Catabasis over $600,000 in funding to support patient and clinical trial site costs. This planned Phase 2 trial is designed to assess safety and pharmacokinetics of edasalonexent and exploratory measures of function including cardiac, skeletal muscle and pulmonary function in non-ambulatory DMD patients.

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 evaluated in the GalaxyDMD open-label extension trial. 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.
