Notes to Condensed Consolidated Financial Statements

(Unaudited)

1.	Organization and Operations

The Company

Astria Therapeutics, Inc. (the “Company”), is a biopharmaceutical company focused on the discovery, development and commercialization of novel therapeutics for allergic and immunological diseases. The Company’s lead product candidate is STAR-0215, a potential best-in-class monoclonal antibody inhibitor of plasma kallikrein in clinical development for the treatment of hereditary angioedema (“HAE”), a rare, debilitating and potentially life-threatening disease. The Company’s second product candidate is STAR-0310, a monoclonal antibody OX40 antagonist that is in preclinical development for the treatment of atopic dermatitis (“AD”), an immune disorder associated with loss of skin barrier function and itching. The Company was incorporated in the State of Delaware on June 26, 2008.

February 2024 Financing

On February 1, 2024, the Company closed an underwritten offering in which the Company sold 10,340,000 shares of common stock at a price of $12.09 per share (the “February 2024 Financing”). The gross proceeds of the February 2024 Financing were $125.0 million and the net proceeds were $117.2 million.

Liquidity

In June 2021, the Company entered into an Open Market Sale Agreement^SM with Jefferies LLC (“Jefferies”), pursuant to which the Company could issue and sell shares of common stock under an at-the-market offering program (the “2021 ATM Program”). In the three months ended March 31, 2024, the Company sold an aggregate of 2,945,806 shares of common stock under the 2021 ATM Program for gross proceeds of $20.6 million and net proceeds of $20.0 million which completed the sale of all available amounts under the 2021 ATM Program. On March 4, 2024, the Company entered into a new Open Market Sale Agreement^SM with Jefferies, pursuant to which the Company is able to issue and sell up to $150.0 million of shares of common stock under an at-the-market offering program (the “2024 ATM Program” and collectively with the 2021 ATM Program, the “ATM Programs”). The Company pays Jefferies commissions of up to 3% of the gross proceeds from any common stock sold through the ATM Programs. As of March 31, 2024, there has been no activity in the 2024 ATM Program, and there was no activity in the 2021 ATM Program during the three months ended March 31, 2023.

As of March 31, 2024, the Company had an accumulated deficit of $600.5 million and had available cash, cash equivalents and short-term investments $369.9 million. The Company estimates its existing cash, cash equivalents, and short-term investments are sufficient to sustain operations for at least twelve months from the issuance of these unaudited condensed consolidated financial statements. The Company has been primarily involved with research and development activities and has incurred operating losses and negative cash flows from operations since its inception. The Company anticipates that it will continue to incur significant operating losses for the next several years as it continues to develop its product candidates. The Company has not generated any product revenues and has financed its operations primarily through public offerings and private placements of its equity securities. There can be no assurance that the Company will be able to obtain additional equity, debt or other financing or generate product revenue or revenues from collaborative partners, on terms acceptable to the Company, on a timely basis or at all. The failure of the Company to obtain sufficient funds on acceptable terms when needed could have a material adverse effect on the Company’s business, results of operations, and financial condition.

The Company is subject to a number of risks similar to other life science companies, including, but not limited to, successful discovery and development of its drug candidates, raising additional capital, development by its competitors of new technological innovations, protection of proprietary technology and regulatory approval and market acceptance of the Company’s products.

2.	Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The accompanying financial statements and the related disclosures are unaudited and have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”). Additionally, certain information and footnote disclosures normally included in the Company’s annual financial statements have been condensed or omitted from this report. Accordingly, these unaudited condensed consolidated financial statements should be read in conjunction with the financial statements as of and for the year ended December 31, 2023 and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023 (the “2023 Annual Report on Form 10-K”).

The unaudited condensed consolidated financial statements have been prepared on the same basis as the audited financial statements. In the opinion of the Company’s management, the accompanying unaudited condensed consolidated financial statements contain all adjustments, including those adjustments that are of a normal and recurring nature, which are necessary to fairly present the Company’s results for the interim periods presented. The results for the three months ended March 31, 2024 are not necessarily indicative of the results for the year ending December 31, 2024 or for any future period.

The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Astria Securities Corporation and Quellis Biosciences, LLC, successor in interest to Quellis. All intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of the Company’s unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the unaudited condensed consolidated financial statements and accompanying notes. Actual results could differ from such estimates.

The Company utilizes certain estimates to record expenses relating to research and development contracts. These contract estimates, which are primarily related to the length of service of each contract and the amount of service provided as of each measurement date, are determined by the Company based on input from internal project management, as well as from service providers.

Net Loss Per Share

Basic net loss per share attributable to common stockholders is calculated by dividing net loss attributable to common stockholders by the weighted average shares outstanding during the period, without consideration for common stock equivalents. The Company has included pre-funded warrants to purchase 1,571,093 shares of common stock at an exercise price of $0.001 per share in its computation of weighted average shares outstanding during the period. Diluted net loss per share attributable to common stockholders is calculated by adjusting weighted average shares outstanding for the dilutive effect of common stock equivalents outstanding for the period, determined using the treasury-stock method. For purposes of the Company’s dilutive net loss per share attributable to common stockholders calculation, stock options and warrants to purchase the Company’s common stock were considered to be common stock equivalents but were excluded from the calculation of diluted net loss per share attributable to common stockholders, as their effect would be anti-dilutive; therefore, basic and diluted net loss per share attributable to common stockholders were the same for all periods presented.

The following common stock equivalents, including Series X Preferred Stock shown as common stock equivalents, were excluded from the calculation of diluted net loss per share for the periods indicated because including them would have had an anti-dilutive effect:


	Three Months Ended March 31,
	2024	2023
Common stock warrants	6,796,280	1,031,820
Stock options	6,052,298	2,562,234
Series X Preferred Stock	5,184,591	5,184,591
	18,033,169	8,778,645

Table of Contents

Cash, Cash Equivalents and Restricted Cash

Cash equivalents are short-term, highly liquid investments that are readily convertible into cash, with original maturities of three months or less and reverse repurchase agreements with a maturity period of one business day at the time of purchase. Cash equivalents are mainly comprised of money market accounts invested in U.S. Treasury securities, corporate debt securities, commercial paper and reverse repurchase agreements with a maturity period of one business day at the time of purchase.

Restricted cash is comprised of deposits with a financial institution used to collateralize letters of credit related to the Company’s lease arrangements. Restricted cash is presented as a component of prepaid expenses and other current assets at March 31, 2024 and other long-term assets at March 31, 2023.

The reconciliation of cash, cash equivalents and restricted cash reported within the applicable condensed consolidated balance sheet that sum to the total of the same such amount shown in the condensed consolidated statement of cash flows is as follows (in thousands):


	March 31,
	2024		2023
Cash and cash equivalents	$	172,012	$	202,301
Restricted cash		163		163
Total	$	172,175	$	202,464

Preferred Stock Discount

In February 2021, the Company issued Series X Preferred Stock in a private placement transaction. It was determined that this transaction resulted in recognition of a beneficial conversion feature, which was valued based on the difference between the price of the shares of common stock on the date of commitment and the conversion price on the closing date, resulting in a total value of $19.6 million. Additionally, the Company incurred total issuance costs of $5.7 million related to the private placement. Both of these features were recorded as a discount on Series X Preferred Stock recognized at the close of the transaction. These features are analogous to preferred dividends and are recorded as a non-cash return to holders of Series X Preferred Stock through additional paid in capital. The discount related to the beneficial conversion feature was recognized through the earliest possible date of conversion, which occurred upon the stockholder approval of the conversion in June 2021. The issuance costs are recognized as a dividend at the time of conversion to common shares. As of March 31, 2024, $24.4 million of the above amounts were accounted for as a non-cash dividend related to shares of Series X Preferred Stock, and $0.9 million remained to be recognized upon future conversion.

Recent Accounting Pronouncements - Adopted

From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) or other standard setting bodies and adopted by the Company as of the specified effective date.

In August 2020, the FASB issued Accounting Standards Update 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging Contracts in Entity’s Own Equity (Subtopic 815-40) (“ASU 2020-06”), which reduces the number of accounting models for convertible debt instruments and convertible preferred stock as well as amends the derivatives scope exception for contracts in an entity’s own equity. The Company adopted this standard on January 1, 2024 with no material impact on the unaudited condensed consolidated financial statements.

In November 2023, the FASB issued Accounting Standards Update 2023-07, Segment Reporting (Topic 280: Improvements to Reportable Segment Disclosures (“ASU 2023-07”). The amendments in this update improve reportable segment disclosure requirements through enhanced disclosures about significant segment expenses. The Company adopted this standard on January 1, 2024 with no material impact on the unaudited condensed consolidated financial statements.

3.Financial Instruments

The tables below present information about the Company’s assets and liabilities that are measured at fair value on a recurring basis as of March 31, 2024 and December 31, 2023, and indicate the fair value hierarchy of the valuation techniques the Company utilized to determine such fair value. In general, fair values determined by Level 1 inputs utilize observable inputs such as quoted prices in active markets for identical assets or liabilities. Fair values determined by Level 2 inputs utilize data points that are either directly or indirectly observable, such as quoted prices, interest rates and yield curves. Fair values determined by Level 3 inputs utilize unobservable data points for which there is little or no market data, which require the Company to develop its own assumptions for the asset or liability. There were no transfers between fair value measurement levels during the three months ended March 31, 2024 and 2023.

The Company’s investment portfolio may include fixed income securities that do not always trade on a daily basis. As a result, the pricing services used by the Company apply other available information as applicable through processes such as benchmark yields, benchmarking of like securities, sector groupings and matrix pricing to prepare valuations. The Company validates the prices provided by its third party pricing services by obtaining market values from other pricing sources and analyzing pricing data in certain instances. The Company also invests in certain reverse repurchase agreements which are collateralized by deposits in the form of U.S. Government Securities and Obligations for an amount no less than 102% of their value. The Company does not record an asset or liability for the collateral as the Company is not permitted to sell or re-pledge the collateral. The collateral has at least the prevailing credit rating of U.S. Government Treasuries and Agencies. The Company utilized a third-party custodian to manage the exchange of funds and ensure that collateral received is maintained at 102% of the value of the reverse repurchase agreements on a daily basis.

The Company accounted for warrants to purchase its stock pursuant to Accounting Standards Codification (“ASC”) Topic 470, Debt, and ASC Topic 480, Distinguishing Liabilities from Equity, and classifies warrants for common stock and preferred stock as liabilities or equity. The warrants classified as liabilities are reported at their estimated fair value and any changes in fair value are reflected in research and development expense. The warrants classified as equity are reported at their estimated fair value with no subsequent remeasurement.

The contractual maturities of all short-term investments held at March 31, 2024 and December 31, 2023 were one year or less. There were 14 short-term investments in an unrealized loss position with an aggregate value of $98.2 million as of March 31, 2024. These investments were in a loss position for less than 12 months and the Company considered the loss to be temporary in nature. The Company considered the decline in market value for these securities to be primarily attributable to economic and market conditions. There were no short-term investments in an unrealized loss position as of December 31, 2023.

Gross realized gains and losses on the sales of short-term investments are included in other income, net. Unrealized holding gains or losses for the period that have been included in accumulated other comprehensive income, as well as gains and losses reclassified out of accumulated other comprehensive income into other income, net, were not material to the Company’s condensed consolidated statements of operations. The cost of investments sold or the amount reclassified out of the accumulated other comprehensive income into other income, net is based on the specific identification method for purposes of recording realized gains and losses. All proceeds in the three month periods ended March 31, 2024 and 2023 related to maturities of underlying investments. The gains on proceeds from maturities of short-term investments were not material to the Company’s condensed consolidated statements of operations for the three months ended March 31, 2024 and 2023.

Overview

We are a biopharmaceutical company focused on the discovery, development and commercialization of novel therapeutics for allergic and immunological diseases. Our focus is to develop first-choice therapies that improve the health and outcomes of patients with allergic and immunological diseases. Our lead product candidate is STAR-0215, a potential best-in-class monoclonal antibody inhibitor of plasma kallikrein in clinical development for the treatment of hereditary angioedema, or HAE, a rare, debilitating and potentially life-threatening disease. STAR-0215 has the potential to be the most patient-friendly chronic treatment option for HAE, based on initial proof-of-concept data in HAE patients and the existing HAE treatment landscape. Our second product candidate is STAR-0310, a monoclonal antibody OX40 antagonist that is in preclinical development for the treatment of atopic dermatitis, or AD, an immune disorder associated with loss of skin barrier function and itching. We believe that with both of these programs, we are advancing a pipeline of products with meaningfully differentiated profiles based on validated mechanisms.

STAR-0215

The treatment options for patients with HAE have improved in recent years, however, there is remaining unmet medical need and the global market for HAE therapy is strong and growing. The goal for STAR-0215 is to develop a best-in-class monoclonal antibody inhibitor of plasma kallikrein able to provide long-acting, effective attack prevention for HAE. Our vision for STAR-0215 is to become the first-choice preventative treatment for HAE with administration every three and six months with the goal of normalizing the lives of people living with HAE. Targeted plasma kallikrein inhibition can prevent HAE attacks by suppressing the pathway that generates bradykinin and causes excessive swelling. STAR-0215 is currently in clinical development and the U.S. Food and Drug Administration, or FDA, has granted Fast Track designation to STAR-0215 for the treatment of HAE.

In February 2023, we advanced STAR-0215 to a Phase 1b/2 trial called ALPHA-STAR, or Astria Long-acting Prophylaxis for Hereditary Angioedema: STAR-0215. This global, multi-center, open-label, single and multiple dose proof-of-concept clinical trial in people with HAE is evaluating safety, tolerability, HAE attack rate, pharmacokinetics, or PK, pharmacodynamics, or PD, and quality of life in patients three and six months after subcutaneous STAR-0215 administration. We reported initial proof-of-concept data in HAE patients in March 2024, as described below. Target enrollment of 16 patients has been achieved and all doses have been administered. The initial efficacy and safety data-cut was as of March 13, 2024.

Cohort 1 evaluated a 450 mg dose and all four patients had completed 6 months of follow-up. Efficacy observations compared to baseline through 6 months of follow-up were as follows:

●

92% reduction in monthly attack rate

●

96% reduction in moderate and severe attacks

●

91% reduction in acute rescue medication use

●

50% of patients were attack-free through 3 months of follow-up

Table of Contents

Cohort 2 evaluated a 600 mg dose followed by a 300 mg dose three months later, on Day 84. We plan to evaluate this dosing regimen in Phase 3. All six patients had completed 3 months of follow-up and three patients had completed 6 months of follow-up. Efficacy observations compared to baseline through 6 months of follow-up were as follows:

●

96% reduction in monthly attack rate

●

98% reduction in moderate and severe attacks

●

94% reduction in acute rescue medication use

●

67% of patients were attack-free

●

100% of patients were attack-free in the first month after dosing, demonstrating rapid onset of action

Cohort 3 received a 600 mg dose followed by a 600 mg dose one month later, on Day 28. Four of six patients had completed 3 months of follow-up. Efficacy observations compared to baseline through 3 months of follow-up were as follows:

●

90% reduction in monthly attack rate

●

100% reduction in moderate and severe attacks

●

95% reduction in acute rescue medication use

●

50% of patients were attack-free

STAR-0215 was generally well-tolerated with no serious treatment-emergent adverse events, or TEAEs, and no discontinuations. There were two treatment-related TEAEs (both mild), one of which was a case of dizziness and the other a transient injection site reaction (rash). There were no injection site reactions of pain.

We expect to report additional data from ALPHA-STAR in the second half of 2024. We are expanding enrollment in ALPHA-STAR in Cohorts 2 and 3 for a total of up to 28 patients in order to accelerate the collection of data to support potential future approvals.

The observed efficacy, PK, PD, and safety and tolerability profile of STAR-0215 support advancement of STAR-0215 into Phase 3 development. To progress STAR-0215 to market as quickly as possible, we plan to focus the Phase 3 program on every 3-month, or Q3M, dosing initially, immediately followed by a second clinical trial to support label expansion to every 6-month, or Q6M, dosing. Pending regulatory feedback, we expect to start a pivotal Q3M Phase 3 trial in the first quarter of 2025, with top-line results expected by year-end 2026.

We have initiated and are enrolling subjects in ALPHA-SOLAR, a long-term open-label trial assessing the long-term safety and efficacy of STAR-0215. We are currently administering STAR-0215 to those patients who have completed ALPHA-STAR and have enrolled in ALPHA-SOLAR. Participants are being assigned to receive STAR-0215 in one of two dosing regimens: either 300mg Q3M or 600mg Q6M. We expect to report initial safety and efficacy data from ALPHA-SOLAR in mid-2025.

STAR-0310

We believe that OX40 inhibition has the potential to treat AD and other diseases. The current treatment options in AD are insufficient to address the needs of many patients, and standard of care treatments include steroids and topical medications which can treat symptoms but do not address the underlying disease. Our goal for STAR-0310 is to reduce disease activity, relapse rate, and treatment burden for patients with moderate-to-severe AD. STAR-0310 was engineered with YTE half-life extension technology to enable infrequent dosing. As a potential long-acting OX40 inhibitor, STAR-0310 aims to address the need for a safe, effective, and infrequently administered AD treatment.

Table of Contents

In 2024, we plan to share preclinical profile results for STAR-0310 and we anticipate submitting an investigational new drug application, or IND, to the FDA for STAR-0310 for the treatment of AD by year-end. If the IND clears, we anticipate initiating a Phase 1a clinical trial of STAR-0310 in healthy subjects in the first quarter of 2025 and reporting initial results from the Phase 1a clinical trial in the third quarter of 2025, including PK and PD data and early signals on safety and tolerability. Assuming positive results from the Phase 1a clinical trial, we plan to initiate a Phase 1b clinical trial of STAR-0310 in patients with AD in the second half of 2025 and would expect to report results from such trial in the second quarter of 2026. The goals of the Phase 1b trial would be to demonstrate initial efficacy in AD as well as show differentiation in safety and tolerability and the potential for a reduced treatment burden as a result of extended half-life as compared to existing therapies.

Underwritten Offerings

On October 16, 2023, we closed an underwritten offering of (i) 8,253,895 shares of our common stock and accompanying common stock warrants to purchase an aggregate of 6,190,418 shares of common stock and (ii), in lieu of common stock to certain investors, pre-funded warrants to purchase up to an aggregate of 1,571,093 shares of common stock and accompanying common stock warrants to purchase up to an aggregate of 1,178,320 shares of common stock, which we refer to as the October 2023 Financing. The gross proceeds of the October 2023 Financing were approximately $64.0 million and net proceeds were $59.5 million.

On February 1, 2024, we closed an underwritten offering of 10,340,000 shares of our common stock, which we refer to as the February 2024 Financing. The gross proceeds of the February 2024 Financing were $125.0 million and the net proceeds were $117.2 million.

Financial Overview

Our business is almost entirely dependent on the success of STAR-0215, which is in clinical development and has only produced results in Phase 1a and Phase 1b/2 clinical testing and in preclinical and nonclinical settings, in addition to STAR-0310, which is in the preclinical stage of development. Our net losses were $19.9 million and $11.2 million for the three months ended March 31, 2024 and 2023, respectively. As of March 31, 2024, we had an accumulated deficit of $600.5 million. We have not generated any product revenues and have financed our operations primarily through public offerings and private placements of our equity securities and have devoted substantially all of our financial resources and efforts to research and development, including preclinical studies and clinical development programs.

As of March 31, 2024, we had $369.9 million in cash, cash equivalents and short-term investments, which we expect will enable us to fund our operating expenses and capital expenditure requirements into mid-2027, including all STAR-0215 program activities through the completion of a planned Q3M Phase 3 pivotal trial as well as advancing our STAR-0310 OX40 program through submission of an IND and early proof-of-concept results from a Phase 1a clinical trial. We have based this estimate on assumptions that may prove to be wrong, and we could use our available capital resources sooner than we currently expect. Advancing the development of STAR-0215, STAR-0310, or any future product candidates will require a significant amount of capital. Our existing cash, cash equivalents and short-term investments will not be sufficient to enable us to fund the completion of development of any of our product candidates, including STAR-0215, STAR-0310 or any future product candidate. We will need to obtain substantial additional funding to complete the development and commercialization of STAR-0215, STAR-0310 or any future product candidates and support our continuing operations, future clinical trials and expansion of our pipeline. Furthermore, our operating plan may change as a result of many factors currently unknown to us, and we may need to seek additional financing to fund our long-term operations sooner than planned. See the section titled “Liquidity and Capital Resources” below for additional information.

Research and Development Expenses

Research and development expenses consist primarily of costs incurred for our research activities, including our drug discovery efforts, and the development of our product candidates, which include:

●

employee-related expenses including salaries, benefits and stock-based compensation expense;

●

expenses incurred under agreements with third parties, including contract research organizations, or CROs, that conduct clinical trials and research and development and preclinical activities on our behalf;

●

the cost of consultants;

●

the cost of lab supplies and acquiring, developing and manufacturing study and clinical trial materials; and

Table of Contents

●

facilities and other expenses, which include direct and allocated expenses for rent and maintenance of facilities, insurance and other supplies.

Research and development costs are expensed as incurred. Nonrefundable advance payments for goods or services to be received in the future for use in research and development activities are deferred and capitalized. The capitalized amounts are expensed as the related goods are delivered or the services are performed.

We typically use our employee, consultant and infrastructure resources across our development programs. We track outsourced development costs by product candidate or development program, but we do not allocate personnel costs, other internal costs or external consultant costs to specific product candidates or development programs. We record our research and development expenses net of any research and development tax incentives we are entitled to receive from government authorities.

The following table summarizes our research and development expenses by program (in thousands):


	Three Months Ended March 31,
	2024		2023
STAR-0215	$	7,136	$	4,140
STAR-0310		2,975		—
Other programs		447		710
Costs not directly allocated to programs:
Employee expenses including cash compensation, benefits and stock-based compensation		4,141		2,746
Consultants and professional expenses, including stock-based compensation		757		308
Facilities		95		67
Other		175		62
Total costs not directly allocated to programs		5,168		3,183
Total research and development expenses	$	15,726	$	8,033

We expect to incur significant research and development expenses in the year ending December 31, 2024, and in future periods in connection with the clinical trials and other activities related to the development of STAR-0215 and the preclinical studies, planned clinical trials and other activities related to the development of STAR-0310. Because of this, we expect that our research and development expenses over the next several quarters will be higher than the prior year periods. Development of STAR-0215, STAR-0310 and any future product candidates is highly uncertain and we cannot reasonably estimate at this time the nature, timing and costs of the efforts that would be necessary to complete the development of any such product candidates. We are also unable to predict when, if ever, material net cash inflows would commence from STAR-0215, STAR-0310 or any other future product candidates. This is due to the fact that we would need to raise substantial additional capital to fund the completion of the clinical development of any such product candidates and the numerous risks and uncertainties associated with developing and commercializing product candidates, including the uncertainties of:

●

establishing an appropriate safety profile with IND-enabling toxicology studies;

●

successful design of, enrollment in, and completion of clinical trials;

●

feedback from the FDA and foreign regulatory authorities on planned trial designs, pre-clinical studies and manufacturing capabilities and plans;

●

changes in the FDA and foreign regulatory approval processes or perspectives that may delay or prevent the approval of new products;

●

receipt of marketing approvals from applicable regulatory authorities;

●

establishing commercial manufacturing capabilities or making arrangements with third-party manufacturers;

●

obtaining and maintaining patent and trade secret protection and regulatory exclusivity;

●

launching commercial sales, if we are able to obtain marketing approval, whether alone or in collaboration with others, and our ability to compete successfully with other products; and

●

maintaining a continued acceptable safety profile following approval.

A change in the outcome of any of these variables with respect to the development of STAR-0215, STAR-0310 or any future product candidate, would significantly change the costs and timing associated with the development of that product candidate.

Table of Contents

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and other related costs, including stock-based compensation, for personnel in executive, finance, accounting, information technology, new product planning, business development, legal and human resources functions. Other significant costs include facility costs not otherwise included in research and development expenses, legal fees relating to patent and corporate matters, and fees for accounting and consulting services.

We anticipate that our general and administrative expenses will increase from their current levels as we continue to grow our company, develop STAR-0215 and STAR-0310, and potentially expand our pipeline to include other product candidates.

Other Income, Net

Other income, net consists of interest income earned on our cash, cash equivalents and short-term investments and net amortization expense on short-term investments, and gains and losses related to foreign currency fluctuations.

Critical Accounting Estimates

This discussion and analysis of our financial condition and results of operations is based on our financial statements, which we have prepared in accordance with United States generally accepted accounting principles. We believe that several accounting policies are important to understanding our historical and future performance. We refer to these policies as critical because these specific areas generally require us to make judgments and estimates about matters that are uncertain at the time we make the estimate, and different estimates—which also would have been reasonable—could have been used. On an ongoing basis, we evaluate our estimates and judgments. We base our estimates on historical experience and other market-specific or other relevant assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

During the three months ended March 31, 2024, there were no material changes to our critical accounting policies as reported in our 2023 Annual Report on Form 10-K.

Research and Development Expenses

Research and development expenses increased by $7.7 million to $15.7 million for the three months ended March 31, 2024 from $8.0 million for the three months ended March 31, 2023, an increase of 96%. The increase in research and development expenses was primarily associated with our STAR-0215 program’s advancement in our multi-site international clinical trials in addition to external research and development costs associated with our STAR-0310 program, including manufacturing and IND-enabling activities. These business developments resulted in a $3.0 million increase in CRO and manufacturing expenses to support the ALPHA-STAR and ALPHA-SOLAR clinical trials in addition to a Phase 3 pivotal trial in 2025, a $3.0 million increase in expenses related to external research, manufacturing, and IND-enabling activities related to the STAR-0310 program, a $1.4 million increase in employee expenses, and a $0.5 million increase in consulting expenses and other expenses, partially offset by a $0.2 million decrease in expenses attributable to other research programs.

As noted above, we expect that our research and development expenses over the next several quarters will be higher than prior periods. We anticipate initiating a Phase 3 pivotal trial for STAR-0215 in the first quarter of 2025 in addition to submitting an IND to the FDA for STAR-0310 for the treatment of AD by year-end 2024. If the IND clears, we anticipate initiating a Phase 1a clinical trial of STAR-0310 in the first quarter of 2025.

General and Administrative Expenses

General and administrative expenses increased by $2.9 million to $8.4 million for the three months ended March 31, 2024 from $5.5 million for the three months ended March 31, 2023, an increase of 54%. The increase in general and administrative expenses was attributable to a $2.0 million increase in employee expenses primarily due to stock-based compensation expenses and company growth to support the advancement of our programs, in addition to a $0.9 million increase in professional services due to increased legal fees and consulting expenses. As noted above, we anticipate that our general and administrative expenses will increase from their current levels as we continue to grow our company.

Other Income, Net

Other income, net increased by $1.9 million to $4.2 million for the three months ended March 31, 2024 from $2.3 million for the three months ended March 31, 2023, an increase of 83%. The increase was primarily attributable to an increase in interest and investment income due to higher yields on our interest-earning assets.

Liquidity and Capital Resources

From our inception through March 31, 2024, we raised an aggregate of $823.3 million through equity financings including private placements of preferred stock before we became a public company, our private placement of preferred stock in February 2021 and registered offerings of our common stock, including our at-the-market offering programs.

As of March 31, 2024, we had $369.9 million in cash, cash equivalents and short-term investments which we expect will enable us to fund our operating expenses and capital expenditure requirements into mid-2027, including all STAR-0215 program activities through the completion of a planned Q3M Phase 3 pivotal trial, as well as advancing our STAR-0310 OX40 program through submission of an IND and early proof-of-concept results from a Phase 1a trial. We have based this estimate on assumptions that may prove to be wrong, and we could use our available capital resources sooner than we currently expect. Furthermore, our operating plan may change as a result of many factors currently unknown to us, and we may need to seek additional financing to fund our long-term operations sooner than planned.

Advancing the development of STAR-0215, STAR-0310, or any future product candidates will require a significant amount of capital and our existing cash, cash equivalents and short-term investments will not be sufficient to enable us to fund the completion of development of any of our product candidates, including STAR-0215, STAR-0310 or any future product candidate. In addition, STAR-0215, STAR-0310, or any future product candidates, if approved, may not achieve commercial success. Our commercial revenues, if any, will be derived from sales of product candidates that we do not expect to be commercially available for years, if at all. Accordingly, we will need to obtain substantial additional funding to complete the development and commercialization of STAR-0215, STAR-0310 or any future product candidates, support our continuing operations, future clinical trials and the expansion of our pipeline. Adequate additional financing may not be available to us on acceptable terms, or at all. The terms of any financing may adversely affect the holdings or the rights of our stockholders. General economic conditions, both inside and outside the United States, including heightened inflation, capital market instability and volatility, interest rate and currency rate fluctuations and economic slowdown or recession as well as pandemics, epidemics and geopolitical events, including civil or political unrest (such as the Ukraine-Russian war and the conflict in the Middle East), may have a significant impact on the availability of funding sources and the terms on which any funding may be available. In addition, market instability and volatility, high levels of inflation and interest rate fluctuations may increase our cost of financing or restrict our access to potential sources of future liquidity. If we fail to raise capital as, and when, needed, we may be unable to continue our operations at planned levels and be forced to modify our business strategies and reduce or terminate our operations. Although we will continue to pursue these plans, there is no assurance that we will be successful in obtaining sufficient funding on terms acceptable to us to fund continuing operations when needed or at all.

October 2023 Financing

On October 16, 2023, we closed the October 2023 Financing, in which we sold (i) 8,253,895 shares of our common stock and accompanying common stock warrants to purchase an aggregate of 6,190,418 shares of common stock and (ii), in lieu of common stock to certain investors, pre-funded warrants to purchase up to an aggregate of 1,571,093 shares of common stock and accompanying common stock warrants to purchase up to an aggregate of 1,178,320 shares of common stock for aggregate gross proceeds of approximately $64.0 million, and net proceeds of $59.5 million.

February 2024 Financing

On February 1, 2024, we closed the February 2024 Financing, in which we sold 10,340,000 shares of our common stock for gross proceeds of $125.0 million and net proceeds of $117.2 million.

At-the-Market Offerings

In June 2021, we entered into an Open Market Sale Agreement^SM with Jefferies LLC, or Jefferies, pursuant to which we could issue and sell shares of common stock under an at-the-market offering program, or the 2021 ATM Program. In the three months ended March 31, 2024, we sold an aggregate of 2,945,806 shares of common stock under the 2021 ATM Program for gross proceeds of $20.6 million and net proceeds of $20.0 million which completed the sale of all available amounts under the 2021 ATM Program. On March 4, 2024, we entered into a new Open Market Sale Agreement^SM with Jefferies, pursuant to which we are able to issue and sell up to $150.0 million of shares of common stock under an at-the-market offering program, or the 2024 ATM Program, and, collectively with the 2021 ATM Program, the ATM Programs. We pay Jefferies commissions of up to 3% of the gross proceeds from any common stock sold through the ATM Programs. As of March 31, 2024, there has been no activity in the 2024 ATM Program, and there was no activity in the 2021 ATM Program during the three months ended March 31, 2023.

Cash Flows

Comparison of the Three Months Ended March 31, 2024 and 2023

The following table provides information regarding our cash flows for the three months ended March 31, 2024 and 2023 (in thousands):


	Three Months Ended March 31,
	2024		2023
Net cash used in operating activities	$	(19,094)	$	(13,253)
Net cash (used in) provided by investing activities		(126,231)		194,992
Net cash provided by financing activities		141,807		37
Net (decrease) increase in cash, cash equivalents and restricted cash	$	(3,518)	$	181,776

Net Cash Used in Operating Activities

Net cash used in operating activities was $19.1 million for the three months ended March 31, 2024 and consisted primarily of a net loss of $19.9 million adjusted for stock-based compensation expense of $2.8 million, non-cash items of $0.7 million, an adjustment to our right of use asset of $0.2 million, and a net increase in net assets of $1.5 million, which resulted primarily from an increase in prepaid expenses and long term deposits of $0.9 million, a decrease in accounts payable of $0.7 million, and a decrease in the lease liability of $0.2 million, partially offset by an increase in accrued expenses of $0.3 million.

Net cash used in operating activities was $13.3 million for the three months ended March 31, 2023 and consisted primarily of a net loss of $11.2 million adjusted for stock-based compensation expense of $1.2 million, an adjustment to our right of use asset of $0.1 million, and a net increase in net assets of $3.4 million, which resulted primarily from a decrease in accrued expenses of $2.5 million, an increase in prepaid expenses of $0.9 million and a decrease in the lease liability of $0.1 million, partially offset by an increase in accounts payable of $0.1 million.

Net Cash Provided by (Used in) Investing Activities

Net cash used in investing activities was $126.2 million for the three months ended March 31, 2024 and consisted primarily of purchases of short-term investments of $1.0 billion, partially offset by maturities of short-term investments of $0.9 billion as the proceeds from maturities from short-term investments were reinvested. Net cash provided by investing activities was $195.0 million for the three months ended March 31, 2023 and consisted primarily of maturities of short-term investments of $290.9 million, partially offset by purchases of short-term investments of $95.9 million.

Net Cash Provided by Financing Activities

Net cash provided by financing activities was $141.8 million for the three months ended March 31, 2024, which was attributable to net proceeds of $117.2 million from the February 2024 Financing, net proceeds of $20.0 million from the 2021 ATM Program and proceeds from exercises of stock options and warrants of $4.6 million. Net cash provided by financing activities was less than $0.1 million for the three months ended March 31, 2023, which was attributable to proceeds from exercises of stock options.

Funding Requirements

Our primary uses of capital are for compensation and related expenses, manufacturing costs for preclinical and clinical materials, third party preclinical and clinical research and development services, clinical costs, legal and other regulatory expenses, and general overhead.

As of March 31, 2024, we had an accumulated deficit of $600.5 million. We have been primarily involved with research and development activities and have incurred operating losses and negative cash flows from operations since our inception.

Based on our current operating plan, we expect that our existing cash, cash equivalents and short-term investments will enable us to fund our operating expenses and capital expenditure requirements into mid-2027. Our estimate as to how long we expect our cash, cash equivalents and short-term investments to be able to fund our operations is based on assumptions that may prove to be wrong, and we could use our available capital resources sooner than we currently expect. Because of the numerous risks and uncertainties associated with research, development and commercialization of biotechnology products, we are unable to estimate the exact amount of our operating capital requirements. Further, changing circumstances, some of which may be beyond our control, could cause us to consume capital significantly faster than we currently anticipate, and we may need to seek additional funds sooner than planned. Our future funding requirements will depend on many factors, including:

●

the progress, timing, costs and results of clinical trials of, and research and preclinical development efforts for STAR-0215, STAR-0310 and any future product candidates, including potential future clinical trials;

●

our ability to enter into and the terms and timing of any collaborations, licensing or other arrangements that we may establish;

●

the number and characteristics of future product candidates that we pursue and their development requirements;

●

the outcome, timing and costs of seeking regulatory approvals;

●

the costs of commercialization activities for any of our product candidates that receive marketing approval to the extent such costs are not the responsibility of any future collaborators, including the costs and timing of establishing product sales, marketing, market access, distribution, supply chain and manufacturing capabilities, and scaling up the manufacturing of drug substance and drug product to clinical and commercial scale and developing a drug device combination, if applicable, securing all raw materials necessary to conduct such scale-up and successfully completing all other activities related thereto;

●

if we obtain marketing approval of any of our product candidates, revenue, if any, received from commercial sales of our product candidates;

●

if we obtain marketing approval of any of our product candidates, our ability to successfully compete against other approved products that are approved or used as treatments for the indications for which our products are approved, including with respect to STAR-0215 in HAE and STAR-0310 in AD;

●

our headcount growth and associated costs;

●

the amount and timing of future milestone and royalty payments potentially payable to Ichnos Sciences SA and Ichnos Sciences Inc., or collectively Ichnos, pursuant to our October 2023 license agreement with Ichnos;

●

the costs of preparing, filing and prosecuting patent applications, maintaining and protecting our intellectual property rights and defending against intellectual property related claims; and

●

the costs of operating as a public company.

Identifying potential product candidates and conducting preclinical testing and clinical trials is a time-consuming, expensive and uncertain process that takes years to complete, and we may never generate the necessary data or results required to obtain marketing approval and achieve product sales. In addition, STAR-0215, STAR-0310 or any future product candidates, if approved, may not achieve commercial success. Our commercial revenues, if any, will be derived from sales of medicines that we do not expect to be commercially available for years, if at all. Accordingly, we will need to continue to rely on additional financing to achieve our business objectives. Adequate additional financing may not be available to us on acceptable terms, or at all.

Table of Contents

Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through a combination of equity offerings, debt financings, collaborations, strategic alliances and licensing arrangements. We do not have any committed external source of funds. To the extent that we raise additional capital through the sale of equity or convertible debt securities, our stockholders’ ownership interests will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect our stockholders’ rights. Debt financing, if available, would result in periodic payment obligations and may involve agreements that include restrictive covenants that limit our ability to take specific actions, such as incurring debt, making capital expenditures or declaring dividends, that could adversely impact our ability to conduct our business.

If we raise funds through collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or to grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

Material Cash Requirements from Known Contractual Obligations

Our material cash requirements from known contractual and other obligations as of March 31, 2024 are primarily related to our sublease agreements for office space. For information related to our future commitments relating to our sublease agreement, see Note 6, “Commitments”, of our condensed consolidated financial statements.

We enter into agreements in the normal course of business with CROs for clinical trials and clinical supply manufacturing and with vendors for preclinical research studies and other services and products for operating purposes. The contracts are cancelable at any time by us, generally upon 60 days’ prior written notice to the CRO, and therefore we believe that our non-cancelable obligations under these agreements are not material.

Our license agreement with Ichnos includes potential milestone payments, tiered royalties and other obligations that are dependent upon the development of products using the intellectual property licensed under the agreement and contingent upon the achievement of development or regulatory approval milestones, as well as commercial milestones. These potential obligations are contingent upon future events and the timing and likelihood of such potential obligations are not known with certainty. For further information regarding this agreement, please see Note 1, “Organization and Operations” in our 2023 Annual Report on Form 10-K.

Item 4. Controls and Procedures

Management’s Evaluation of our Disclosure Controls and Procedures

We maintain disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, or the Exchange Act) that are designed to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is (1) recorded, processed, summarized, and reported within the time periods specified in the U.S. Securities and Exchange Commission’s rules and forms and (2) accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.

Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q. Our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Our principal executive officer and principal financial officer have concluded based upon the evaluation described above that, as of March 31, 2024, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

During the three months ended March 31, 2024, there were no changes in our internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15(d)-15(f) promulgated under the Exchange Act, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
