-- MoveDMD Trial Progressing, Part C Interim Results Expected in Q3 2017 --

-- Rare Disease Pipeline Programs Advancing in Cystic Fibrosis and Neurodegenerative Diseases --

CAMBRIDGE, Mass.--(BUSINESS WIRE)--May 11, 2017-- Catabasis Pharmaceuticals, Inc. (NASDAQ:CATB), a clinical-stage biopharmaceutical company, today reported financial results for the first quarter ended March 31, 2017, and reviewed recent business progress.

“We made important progress across our portfolio in the first quarter, including the presentation of encouraging results from our edasalonexent MoveDMD trial and the advancement of our rare disease pipeline,” said Jill C. Milne, Ph.D., Chief Executive Officer of Catabasis. “Our recently completed prespecified analysis of functional assessments in Part B of the MoveDMD trial strengthens our confidence in the potential of edasalonexent as a novel treatment for boys with Duchenne muscular dystrophy.”

Dr. Milne continued, “We see consistent numerical improvements across prespecified functional analyses of boys treated with edasalonexent. We expect to report interim results from Part C of the MoveDMD trial in the third quarter, and we look forward to gaining important information on the persistence of treatment signals with edasalonexent as well as determining functional endpoints for possible future clinical trials. The MoveDMD trial is progressing as planned, and we are focused on the next steps for the development of edasalonexent while continuing to advance our pipeline programs in cystic fibrosis and neurodegenerative diseases.”

Recent and Upcoming Corporate Highlights

Edasalonexent (CAT-1004) and the MoveDMD Trial

• Continued execution of open-label extension (Part C) of the MoveDMD trial in which patients are treated with edasalonexent following completion of Part B. The institutional review boards have approved moving all boys in Part C to the higher 100 mg/kg/day dose group of edasalonexent and extending Part C to 60 weeks. Catabasis intends to report results from Part C in 2017, with an interim update in Q3 after all boys participating have completed 24 weeks of dosing with edasalonexent.
• In April, presented data from the MoveDMD trial of edasalonexent at the American Academy of Neurology 69^th Annual Meeting. The prespecified analysis of Part B data showed numerical improvement in rates of change across five functional assessments for patients on 12 weeks of edasalonexent compared to off-treatment prior to Part B dosing. These results are in addition to and consistent with numerical improvements in the same functional assessments with edasalonexent compared to placebo as reported in the top-line results from Part B in January. These functional assessments are meaningful to boys affected by Duchenne and are known to correlate with loss of milestones and disease progression. The MoveDMD trial was not powered for functional assessments and these analyses were generally not statistically significant.
• In March, reported results from the Catabasis and Sarepta joint research collaboration showing increased dystrophin expression in the mdx mouse with edasalonexent in combination with an exon-skip modality. The companies believe that these results warrant further research.
• In January, the primary endpoint for Part B of MRI T2, an exploratory early biomarker, was not met. However, we continue to see numerical improvements across the functional assessments, as described above, which have precedence as endpoints in pivotal trials in DMD.

Additional Rare Disease Programs

• In January, published research on CAT-5571, a novel activator of autophagy and potential oral treatment for cystic fibrosis (CF), in the Journal of Medicinal Chemistry; upcoming presentation on CAT-5571 planned at the European Cystic Fibrosis Conference in June.
• Continued ongoing preclinical activities exploring the potential of CAT-4001 in diseases such as amyotrophic lateral sclerosis (ALS) and Friedreich’s ataxia.

First Quarter 2017 Financial Results

Cash Position: As of March 31, 2017, Catabasis had cash and cash equivalents of $31.8 million, compared to $38.5 million in cash, cash equivalents and available-for-sale securities as of December 31, 2016. Catabasis expects that its current cash and cash equivalents as of April 30, 2017, will fund operating expenses, debt service and capital expenditure requirements based on its current operating plan for at least 12 months from today. Net cash used in operating activities for the three months ended March 31, 2017 was $8.1 million, compared to $9.1 million for the three months ended March 31, 2016.

R&D Expenses: Research and development expenses were $5.4 million for the three months ended March 31, 2017, compared to $6.4 million for the three months ended March 31, 2016. The decrease in research and development expenses was primarily attributable to the completion of certain clinical activities.

G&A Expenses: General and administrative expenses were $2.4 million for the three months ended March 31, 2017, compared to $2.8 million for the three months ended March 31, 2016. The decrease in general and administrative expenses was primarily attributable to decreased G&A headcount.

Operating Loss: Loss from operations was $7.8 million for the three months ended March 31, 2017, compared to $9.2 million for the three months ended March 31, 2016.

Net Loss: Net loss was $7.9 million, or $0.41 per share, for the three months ended March 31, 2017, compared to a net loss of $9.4 million for the three months ended March 31, 2016.

About Edasalonexent (CAT-1004)

Edasalonexent (CAT-1004) is an investigational oral small molecule that is being developed as a potential disease-modifying therapy for all patients affected by DMD, regardless of their underlying mutation. Edasalonexent inhibits NF-kB, a protein that is activated in DMD and drives inflammation and fibrosis, muscle degeneration and suppresses muscle regeneration. We are currently conducting the MoveDMD trial, a three-part clinical trial investigating the safety and efficacy of edasalonexent in boys ages 4 – 7 affected with DMD (any confirmed mutation). The third part of the trial, an open-label extension with edasalonexent, is ongoing. 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.

About CAT-5571

Catabasis is developing CAT-5571 as a potential oral treatment for cystic fibrosis (CF) with potential effects on both the cystic fibrosis transmembrane conductance regulator (CFTR) and on the clearance of Pseudomonas aeruginosa. CAT-5571 is a small molecule that activates autophagy, a process that maintains cellular homeostasis and host defense mechanisms, and is known to be impaired in CF. Catabasis has shown in preclinical studies that CAT-5571, in combination with lumacaftor/ivacaftor, enhances cell-surface trafficking and function of CFTR with the F508del mutation. Catabasis has also shown that CAT-5571 enhances the clearance of P. aeruginosa infection in preclinical models of CF.

About CAT-4001

Catabasis is developing CAT-4001 as a potential treatment for neurodegenerative diseases such as Friedreich’s ataxia (FA) and amyotrophic lateral sclerosis (ALS). CAT-4001 is a small molecule that activates Nrf2 and inhibits NF-kB, two pathways that have been implicated in FA and ALS. Catabasis has shown that CAT-4001 modulates the Nrf2 and NF-kB pathways in both cellular assays and animal models.
