BOSTON, Mass., March 22, 2023 - Astria
Therapeutics, Inc. (NASDAQ:ATXS), a biopharmaceutical company developing STAR-0215 for the treatment of 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, 2022 and provided a corporate update.
"We made excellent progress with our STAR-0215
program in 2022, culminating in the promising initial Phase 1a results. These results support our vision for STAR-0215 to be the first-choice
preventative therapy for HAE," said Jill C. Milne, Ph.D., Chief Executive Officer of Astria. "The
recent initiation of our ALPHA-STAR Phase 1b/2 trial marked an important step towards our goal of reducing the disease and treatment burden
as we work to normalize the lives of people with HAE. We look forward to the initial proof-of-concept results from ALPHA-STAR expected
STAR-0215 Clinical Development
| Positive preliminary results from the Phase 1a clinical trial of STAR-0215 in healthy subjects were announced in December 2022 and initial unblinded results from the first three cohorts were presented at the American Academy of Allergy Asthma, and Immunology Annual Meeting (AAAAI) in February 2023. STAR-0215 was well-tolerated at all doses studied. The results showed rapid and sustained drug levels, with an estimated half-life of up to 117 days and sustained target engagement with plasma kallikrein inhibition for at least three months. These results establish early proof of concept for STAR-0215 as a long-acting preventative therapy for HAE. | ||
| The Company initiated the ALPHA-STAR Phase 1b/2 trial of STAR-0215 in people with HAE in February 2023. Initial proof-of-concept results are expected in mid-2024. The ALPHA-STAR trial is a global, open-label, proof-of-concept trial enrolling patients with HAE types I and II that is evaluating safety and tolerability, changes in HAE attack rate, pharmacokinetics, pharmacodynamics, and quality-of-life assessments. Following an initial run-in period, qualifying participants will be enrolled in either single or multiple dose cohorts. Data from up to 18 participants will evaluate efficacy and safety, and comparisons will be made against data collected in the run-in period. Pending proof-of-concept results from the ALPHA-STAR trial, Astria expects to progress directly to a pivotal trial. | ||
| Astria is also evaluating the potential for administration of STAR-0215 every six months in additional cohorts in the Phase 1a trial, with preliminary results expected in the fourth quarter of 2023. These data, in conjunction with the ALPHA-STAR results, are expected to inform plans for the pivotal trial. |
Fourth Quarter and Full Year 2022 Financial
Position: In December 2022, Astria closed a $115.0 million underwritten offering of common stock. As
of December 31, 2022, Astria had cash, cash equivalents, and short-term investments of $226.4 million,
compared to $116.6 million as of September 30, 2022. The Company expects that it has sufficient
cash to fund its current operating plan through the first half of 2025. Net cash used in operating activities for the three months ended
December 31, 2022, was $10.7 million, compared to $6.3 million
for the three months ended December 31, 2021. Net cash used in operating activities for the full year 2022 was $43.5 million, compared
to $30.2 million for the full year 2021.
Expenses: Research and development expenses were $9.6 million for the three months ended
December 31, 2022, compared to $5.7 million for the three months ended December 31, 2021, and $34.3 million for the full year 2022,
compared to $15.6 million for the full year 2021. The increase in research and development expenses was associated with STAR-0215's
advancement through IND-enabling activities into clinical trials.
Expenses: General and administrative expenses were $4.7 million for the three months ended December 31, 2022, compared to $3.8 million
for the three months ended December 31, 2021, and $19.2 million for the full year 2022, compared to $14.8 million for the full year 2021.
Loss: Loss from operations was $14.3 million for the three months ended December 31, 2022, compared to $9.5 million for the three
months ended December 31, 2021, and $53.5 million for the full year 2022, compared to $195.0 million for the full year 2021. The year-over-year
decrease in net loss was largely attributable to the $164.6 million in acquired in-process R&D expense associated with acquiring
Quellis Biosciences in 2021.
Net loss was $13.3 million for the three months ended December 31, 2022, compared to a net loss of $9.5 million for the three months
ended December 31, 2021, and $51.8 million, or $3.55 per share for the full year 2022, compared to $194.9 million, or $21.84 per share,
for the full year 2021.
Per Share Basic and Diluted: Net loss per share basic and diluted was $0.72 for the three months ended December 31, 2022, compared
to a net loss basic and diluted of $0.73 per share for the three months ended December 31, 2021.
