Catabasis Pharmaceuticals Announces New Company Name, Astria Therapeutics, Highlighting New Company Focus

BOSTON – Catabasis Pharmaceuticals, Inc. (NASDAQ:CATB), a biopharmaceutical company developing STAR-0215 for the treatment of hereditary angioedema (HAE), today announced its new name, Astria Therapeutics, Inc. (“Astria” or the “Company”). The name Astria originates from the Greek word for star, reflecting the Company’s commitment to having patients serve as guiding stars. Astria’s mission is to bring hope with life-changing therapies to patients and families. Astria expects to begin trading under the new ticker symbol “ATXS” on the Nasdaq Global Select Market at market open on September 9, 2021, and the new website, www.astriatx.com, launched today containing information about STAR-0215, HAE, and a new corporate presentation.

“The name Astria embodies our commitment to put patients first in all that we do,” said Jill C. Milne, Ph.D., Chief Executive Officer of Astria Therapeutics. “Following the acquisition of Quellis earlier this year, our company is focused on tackling the debilitating disease hereditary angioedema, with the broader goal of addressing the unmet needs of patients with rare and niche allergic and immunological diseases. We are advancing STAR-0215 as a differentiated and potentially the most patient-friendly preventative treatment option with dosing once every three months or longer. We are proud to launch Astria Therapeutics and bring our team’s combination of experience, passion, and compassion to our future vision and our commitment to patients and their families.”

Astria’s lead program, STAR-0215 (formerly QLS-215), was named to reflect the goal of having patients at the forefront of Astria’s scientific development. STAR-0215 is currently in preclinical development for the treatment of HAE, a rare genetic disorder characterized by severe, recurrent, unpredictable, painful, and sometimes life-threatening swelling in the face, limbs, abdomen, and airway. Astria is developing STAR-0215 to be a long-acting monoclonal antibody inhibitor of plasma kallikrein, dosed once every 3 months or longer, with the goal of providing the most patient-friendly preventative treatment option for people living with HAE. The company expects to file an Investigational New Drug (IND) application for STAR-0215 in mid-2022 and plans to initiate a Phase 1 clinical trial with initial proof of concept results anticipated by year end 2022.

Astria is led by an experienced management team and Board of Directors. The management team was assembled with individuals who have deep expertise in drug discovery and development and commercialization in rare and niche disease areas. The team, led by Jill C. Milne, Ph.D., includes Noah Clauser, Chief Financial Officer, Ben Harshbarger, Chief Legal Officer, Andrew A. Komjathy, Chief Commercial Officer, Andrea Matthews, Senior Vice President, Corporate Affairs, Keri McGrail, Senior Vice President, Human Resources, and Andrew Nichols, Ph.D., Chief Scientific Officer. Astria’s experienced Board of Directors consists of Kenneth Bate, Chair of the Board, Joanne T. Beck, Ph. D., Fred Callori, Hugh M. Cole, Michael D. Kishbauch, Gregg Lapointe, Jill C. Milne, and Jonathan Violin, Ph.D.

Earlier this year, the Company acquired Quellis Biosciences (“Quellis”), and lead program STAR-0215. In conjunction with the acquisition, the Company raised approximately $110 million, before deducting placement agent and other offering expenses, in a private placement to a group of institutional accredited investors led by Perceptive Advisors, with participation from Fairmount Funds Management LLC, RA Capital Management, Cormorant Asset Management, Venrock Healthcare Capital Partners, Logos Capital, Boxer Capital, Acorn Bioventures, Commodore Capital, Surveyor Capital (a Citadel company), Acuta Capital Partners, Sphera Healthcare, and Serrado Capital LLC. As of June 30, 2021, Astria had $139.5 million in cash and cash equivalents. Astria expects that it has sufficient cash to fund its current operating plan through 2023. ATXS common stock will trade under the new CUSIP number 04635X102.
