Catabasis Pharmaceuticals Reports Third Quarter 2018 Financial Results and Reviews Business Progress

-- Edasalonexent Phase 3 PolarisDMD Trial in Duchenne Muscular Dystrophy Underway and Starting Enrollment --

Catabasis Pharmaceuticals, Inc. (NASDAQ:CATB), a clinical-stage biopharmaceutical company, today reported financial results for the third quarter ended September 30, 2018, and reviewed recent business progress.

“We have made great advancements across our edasalonexent program over the last quarter. Clinical trial sites for our Phase 3 PolarisDMD trial are now open for enrollment and we are receiving tremendous interest and positive feedback from families and physicians, reflecting the high level of unmet need in Duchenne and enthusiasm for edasalonexent,” said Jill C. Milne, Ph.D., Chief Executive Officer of Catabasis. “We presented new data showing preserved muscle function and stabilized disease progression following 72 weeks of edasalonexent treatment compared to control. We also presented data that could potentially contribute to establishing MRI as an endpoint for clinical outcome in Duchenne. We are excited to advance our understanding of the potential cardiac benefits of edasalonexent through a preclinical collaboration with Dr. Mammen from UT Southwestern who treats patients with Duchenne and Becker muscular dystrophies. Together, these advancements support the potential value of edasalonexent and get us closer to our goal of making edasalonexent available to all those affected by Duchenne with the hope of enabling patients to maintain their functional abilities longer.”

Recent and Upcoming Corporate Highlights

• Multiple sites open for enrollment for the Phase 3 PolarisDMD clinical trial evaluating edasalonexent in boys affected by Duchenne muscular dystrophy (DMD)
  • The Phase 3 PolarisDMD trial is a one-year, randomized, double-blind, placebo-controlled trial. Catabasis plans to enroll approximately 125 patients ages 4 to 7 (up to 8^th birthday) regardless of mutation type who have not been on steroids for at least 6 months.
  • Top-line results from the Phase 3 PolarisDMD trial are expected in the second quarter of 2020, and the trial is intended to support an application for commercial registration of edasalonexent.

• New MoveDMD Phase 2 trial and open-label extension data through 72 weeks of edasalonexent treatment
  • Preserved muscle function and sustained disease-modifying effects in all assessments of physical function in boys with DMD was seen through 72 weeks of edasalonexent treatment compared to the off-treatment control period. Data were presented at the International Congress of the World Muscle Society in October 2018.
  • Significant decreases in muscle enzymes through 72 weeks were also seen in boys treated with edasalonexent, supporting the durability of edasalonexent treatment effects and positive effects on muscle integrity.
  • Significantly decreased heart rate towards age-normative values was observed and supports the potential beneficial cardiac effects of edasalonexent. Boys with DMD in this age range typically have elevated heart rates, which is the first cardiac manifestation in boys with DMD. Cardiomyopathy is the leading cause of mortality in DMD.
  • Edasalonexent continued to be well tolerated with no safety signals observed in the trial. Boys treated with edasalonexent continued to follow age-appropriate growth curves with age-appropriate increases in weight and height.
  • Catabasis expects to present additional clinical data from the MoveDMD trial with edasalonexent in 2019.
• New magnetic resonance imaging (MRI) data support MRI T2 as a potential marker of clinical outcome in DMD
  • Data from ImagingDMD, the largest natural history database of MRI measurements in more than 150 boys with DMD, show a strong correlation of lower leg composite MRI T2 with clinically relevant functional abilities and DMD disease progression.
  • These results highlight the clinical importance of the significant improvement observed in the Catabasis Phase 2 MoveDMD trial and open-label extension following 12, 24, 36 and 48 weeks of edasalonexent treatment for lower leg MRI T2 compared to the off-treatment control period.
  • ImagingDMD and MoveDMD data were presented at the International Congress of the World Muscle Society in October 2018.
• Preclinical collaboration with University of Texas Southwestern (UT Southwestern) to explore the potential benefits of edasalonexent on cardiac function in Duchenne and Becker muscular dystrophies
  • The collaboration is with Pradeep Mammen, M.D., founder and Medical Director of the Neuromuscular Cardiomyopathy Clinic at the UT Southwestern Medical Center and Co-Director of the Nation Institute of Health Sponsored UT Southwestern Senator Paul D. Wellstone Muscular Dystrophy Cooperative Research Center.

About Edasalonexent (CAT-1004)
Edasalonexent (CAT-1004) is an investigational oral small molecule that is being developed as a potential new standard of care for all patients affected by DMD, regardless of their underlying mutation. Edasalonexent inhibits NF-kB, which is a key link between loss of dystrophin and disease progression in DMD. NF-kB has a fundamental role in skeletal and cardiac muscle disease in DMD. We are currently enrolling our global Phase 3 PolarisDMD trial to evaluate the efficacy and safety of edasalonexent for registration purposes. 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. Edasalonexent continues to be dosed in the open-label extension of the MoveDMD trial. 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.
