Catabasis Pharmaceuticals Reports Third Quarter 2015 Financial Results and Recent Corporate Highlights

— MoveDMDSM trial of CAT-1004 in Duchenne Muscular Dystrophy (DMD) Progressing —

— Orphan, Rare Pediatric Disease and Fast Track Designations Received for CAT-1004 in DMD —

— Phase 2a Trial for CAT-2054 in Hypercholesterolemia Actively Recruiting —

CAMBRIDGE, MA, November 12, 2015 — Catabasis Pharmaceuticals, Inc. (NASDAQ:CATB), a clinical-stage drug development company built on a pathway pharmacology technology platform, today announced financial results for the third quarter ended September 30, 2015 and corporate highlights.

“Catabasis made important advancements in both of our clinical-stage programs during the third quarter of 2015,” commented Jill C. Milne, Ph.D., chief executive officer of Catabasis. “We are now scheduling the final cohort for Part A of the MoveDMD trial of CAT-1004, which we believe has the potential to be a disease-modifying therapy that promotes muscle regeneration in patients with DMD, regardless of the underlying mutation. Additionally, we have started recruiting for our Phase 2a trial of CAT-2054 for hypercholesterolemia and we expect to initiate dosing in the fourth quarter of 2015.”

Recent and Upcoming Corporate Highlights

·                  MoveDMD trial of CAT-1004 in Duchenne Muscular Dystrophy Progressing

We currently are scheduling the final cohort of Part A of the MoveDMD trial, a Phase 1 / 2 clinical trial of CAT-1004 for the treatment of DMD. We expect to release safety, tolerability and pharmacokinetics results from Part A of the MoveDMD trial in early Q1 2016.

·                  Multiple Regulatory Designations Received for CAT-1004 in DMD

During the third quarter, we received Fast Track and Rare Pediatric Disease designations from the FDA and in October the European Commission granted Orphan Medicinal Product designation for CAT-1004 for the treatment of DMD.

·                  Phase 2a Trial for CAT-2054 in Hypercholesterolemia Actively Recruiting

We announced positive top-line Phase 1 data for CAT-2054 for the treatment of hypercholesterolemia.  We have started recruiting for our Phase 2a trial of CAT-2054 for hypercholesterolemia and we expect to initiate dosing in the fourth quarter of 2015.

Third Quarter 2015 Financial Results

Cash Position: At September 30, 2015, Catabasis had cash and cash equivalents of $72.7 million, compared to $14.7 million as of December 31, 2014. Net cash used in operating activities for the three months ended September 30, 2015 was $7.8 million, compared to $4.7 million for the three months ended September 30, 2014. Net cash used in operating activities for the nine months ended September 30, 2015 was $21.1 million, compared to $14.5 million for the nine months ended September 30, 2014.

R&D Expenses: Research and development expenses were $5.8 million for the three months ended September 30, 2015, compared to $4.5 million for the three months ended September 30, 2014, and $16.4 million for the nine months ended September 30, 2015, compared to $11.4 million for the nine months ended September 30, 2014.  The increases in research and development expenses for the 2015 periods relative to the 2014 periods were primarily attributable to increased direct program costs related to the initiation of the CAT-1004 MoveDMD trial in 2015 and increased employee compensation costs.

G&A Expenses: General and administrative expenses were $2.4 million for the three months ended September 30, 2015, compared to $1.4 million for the three months ended September 30, 2014, and $6.0 million for the nine months ended September 30, 2015, compared to $4.4 million for the nine months ended September 30, 2014.  The increases in general and administrative expenses for the 2015 periods relative to the 2014 periods were primarily attributable to increased employee compensation costs and increased consulting and professional expenses to support our overall growth.

Operating Loss: Loss from operations was $8.2 million for the three months ended September 30, 2015, compared to $6.0 million for the three months ended September 30, 2014, and $22.3 million for the nine months ended September 30, 2015, compared to $15.8 million for the nine months ended September 30, 2014.

Net Loss: Net loss was $8.5 million, or $0.55 per share, for the three months ended September 30, 2015, compared to a net loss of $6.0 million for the three months ended September 30, 2014.

About CAT-1004

CAT-1004 is an oral small molecule that inhibits activated NF-kB, a protein that coordinates cellular response to muscular damage, stress and inflammation and plays an important role in muscle health. In skeletal muscle, activated NF-kB drives muscle degeneration and suppresses muscle regeneration. In animal models of DMD, CAT-1004 inhibited activated NF-kB, reduced muscle inflammation and degeneration and increased muscle regeneration. In Phase 1 clinical trials, CAT-1004 inhibited activated NF-kB and was well tolerated with no observed safety concerns. The FDA has granted CAT-1004 orphan drug, fast track and rare pediatric disease designations for the treatment of DMD. The European Commission has granted CAT-1004 orphan medicinal product designation for DMD. Catabasis is currently conducting the MoveDMD Phase 1 / 2 trial of CAT-1004 in 4-7 year-old boys with DMD.

About CAT-2054

CAT-2054 is an investigational oral drug initially being developed for the treatment of hypercholesterolemia in patients for whom existing therapies are insufficient. By modulating the SREBP pathway, CAT-2054 may inhibit production of important cholesterol metabolism proteins such as PCSK9, HMG-CoA reductase, ATP citrate lyase and NPC1L1. If approved, CAT-2054 may have the potential to be the first therapy to simultaneously modulate cholesterol synthesis, clearance and absorption. Catabasis has completed a Phase 1 trial of CAT-2054 in healthy volunteers, announced positive top-line data and is actively recruiting patients for the Phase 2a trial of CAT-2054 in patients with hypercholesterolemia.
