Astria Therapeutics Reports Fourth Quarter and Full Year 2021 Financial Results and Provides a Corporate Update

BOSTON--(BUSINESS WIRE)-- Astria Therapeutics, Inc. (NASDAQ:ATXS), a biopharmaceutical company developing STAR-0215 for hereditary angioedema (HAE) and focused on life-changing therapies for rare and niche allergic and immunological diseases, today reported financial results for the fourth quarter and full year ended December 31, 2021 and provided a corporate update.

“We are excited to advance STAR-0215 to the clinic this year with the planned initiation of our Phase 1a study,” said Jill C. Milne, Ph.D., Chief Executive Officer of Astria. “STAR-0215 was created with a clear vision aimed at reducing treatment burden for HAE patients with dosing once every three months or longer. Our goals for the Phase 1a trial are to evaluate safety and tolerability, demonstrate inhibition of plasma kallikrein activity, and establish the prolonged half-life of STAR-0215. We expect initial results from this trial by the end of this year.”

STAR-0215 for the Treatment of HAE

• Lead program STAR-0215 is a monoclonal antibody inhibitor of plasma kallikrein designed to provide long-acting, effective attack prevention for HAE with dosing once every three months or longer. The goal for STAR-0215 is to provide the most patient-friendly preventative treatment option for people living with HAE.
• HAE is a rare genetic disorder characterized by severe, recurrent, unpredictable, painful, and sometimes life-threatening swelling in the face, limbs, abdomen, and airway. Targeted plasma kallikrein inhibition can prevent HAE attacks by suppressing the pathway that generates bradykinin and causes excessive swelling.
• Astria is on track to file an Investigational New Drug application for STAR-0215 in the middle of this year and plans to initiate a Phase 1a clinical trial shortly thereafter with initial results anticipated by year end. The Phase 1a clinical trial is planned to be conducted in healthy volunteers and evaluate several single ascending dose cohorts with subcutaneous administration. The goals of this initial proof of concept trial are to demonstrate safety and tolerability, establish prolonged half-life of STAR-0215, and to demonstrate inhibition of plasma kallikrein activity. We plan to initiate a Phase 1b/2 trial in patients with HAE in 2023.
• Astria presented new preclinical data demonstrating how STAR-0215 binds to plasma kallikrein at the American Academy of Allergy, Asthma, and Immunology Annual Scientific Meeting in February.

Fourth Quarter and Full Year 2021 Financial Results

Cash Position: As of December 31, 2021, Astria had cash, cash equivalents and short-term investments of $125.5 million, compared to $131.8 million as of September 30, 2021. The Company expects that it has sufficient cash to fund its current operating plan through 2023. Net cash used in operating activities for the three months ended December 31, 2021, was $6.3 million, compared to $8.1 million for the three months ended December 31, 2020. Net cash used in operating activities for the full year 2021 was $30.2 million, compared to $32.5 million for the full year 2020.

R&D Expenses: Research and development expenses were $5.7 million for both the three months ended December 31, 2021 and 2020, and $15.6 million for the full year 2021, compared to $25.6 million for the full year 2020.

G&A Expenses: General and administrative expenses were $3.8 million for the three months ended December 31, 2021, compared to $3.2 million for the three months ended December 31, 2020, and $14.8 million for the full year 2021, compared to $11.8 million for the full year 2020.

The year-over-year increase in net loss was largely attributable to the $164.6 million in acquired in-process R&D expense associated with acquiring Quellis Biosciences.
