Catabasis Pharmaceuticals Reports Fourth Quarter and Full Year 2018 Financial Results and Reviews Business Progress

-- Edasalonexent Phase 3 PolarisDMD Trial Globally Enrolling Boys with Duchenne Muscular Dystrophy --

Catabasis Pharmaceuticals, Inc. (NASDAQ:CATB), a clinical-stage biopharmaceutical company, today reported financial results for the fourth quarter and full year ended December 31, 2018, and reviewed recent business progress.

“We are off to a strong start in 2019, executing on our Phase 3 trial and further strengthening our financial position and Board of Directors to support our plans for transitioning to a commercial-stage organization. We continue to generate valuable data on edasalonexent that further reinforce its potential as a foundational therapy for Duchenne,” said Jill C. Milne, Ph.D., Chief Executive Officer of Catabasis. “We look forward to building on this momentum as we work toward our goal of bringing hope and life-changing therapies to patients and their families.”

Recent and Upcoming Corporate Highlights

• The Phase 3 PolarisDMD clinical trial evaluating edasalonexent in boys affected by Duchenne muscular dystrophy (DMD) is progressing well with patients enrolling at clinical trial sites globally.
  • 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.

• Recent data from the MoveDMD trial continue to support edasalonexent as a potential foundational treatment for DMD.
  • Boys treated with corticosteroids, the current standard of care in DMD, typically experience excess weight gain, curtailed growth and substantially increased body mass index (BMI). In contrast, positive growth data from the MoveDMD trial showed boys treated with edasalonexent grew age appropriately in both height and weight, resulting in decreased BMI that approached the average BMI for unaffected boys.
  • In addition to positive efficacy and safety results with edasalonexent as a monotherapy, MoveDMD also provided the foundation for combination therapy for the treatment of DMD. The combination of edasalonexent and the approved therapy EXONDYS 51^®, developed by Sarepta Therapeutics, was well tolerated with no safety signals. Two boys received this combination for an average of 1 year. These clinical safety data combined with preclinical data showing edasalonexent increased dystrophin expression in combination with exon-skipping therapy support the potential of edasalonexent to enhance dystrophin-targeted therapies such as EXONDYS 51 and other therapies in development.
• Catabasis’ Board of Directors was strengthened with new appointments of Gregg Lapointe and Joanne T. Beck, Ph.D.
• Catabasis closed a $20 million underwritten public offering in February 2019. The proceeds will be used for clinical trial and certain NDA-enabling activities; initial investments in commercial and medical affairs infrastructure to support our planned transition to a commercial-stage company; and for working capital and other general corporate purposes.

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.
