WAYNE, Pa., August 7, 2025 -- Aclaris Therapeutics, Inc. (NASDAQ: ACRS), a clinical-stage biopharmaceutical company focused on developing novel product candidates for immuno-inflammatory diseases, today announced its financial results for the second quarter of 2025 and provided a corporate update.
“Aclaris is in a period of strong execution throughout the business as we advance our innovative therapies toward our goal of improving therapeutic options for patients with certain I&I diseases,” stated Dr. Neal Walker, Chief Executive Officer and Chair of the Board of Directors of Aclaris. “For example, the results from the single arm Phase 2a clinical trial of our ITK/JAK3 inhibitor ATI-2138 represent a significant achievement for our ITK franchise by both confirming the strong tolerability profile and mechanism of ATI-2138 in AD ahead of our planned alopecia areata clinical trial and validating ITK as an important therapeutic target. Importantly, with an expected cash runway that funds our operations into the second half of 2028, we have sufficient capital to execute our strategic plan. We are also exploring additional non-dilutive opportunities to extend our cash runway even further.”
Second Quarter 2025 Highlights and Recent Updates
Pipeline:
| ● | Achieved Primary and Key Secondary Endpoints in Phase 2a Trial of ATI-2138, a Potent and Selective Investigational Inhibitor of ITK and JAK3: Positive results from this open-label, single arm trial further confirmed the favorable tolerability profile of ATI-2138, demonstrated clinically meaningful improvements from baseline in assessments of disease severity in patients with moderate-to-severe AD receiving low doses of ATI-2138, and validated ITK as a therapeutic target. Overall, these results provide evidence that the contribution of ITK may enable ATI-2138, even at low doses, to achieve efficacy results comparable to approved JAK inhibitors in moderate-to-severe AD, but with improved tolerability and without the significant safety risks typically associated with JAK inhibition.

| ● | Initiated Dosing in Phase 2 Trial of Potential Best-in-Class Investigational Anti-TSLP Monoclonal Antibody Bosakitug: Patient dosing is ongoing in the randomized, double-blind, placebo-controlled global Phase 2 trial designed to evaluate bosakitug in approximately ninety (90) patients with moderate-to-severe AD. The Company expects to provide top line results in the second half of 2026. (press release here) |

| ● | Initiated Dosing in Phase 1a/1b Program for Potential Best-in-Class Investigational Bispecific Anti-TSLP/IL-4R Antibody ATI-052: Dosing is ongoing in the randomized, blinded, placebo-controlled Phase 1a portion, designed to evaluate single and multiple ascending doses of ATI-052 in healthy adults. The Phase 1b proof-of-concept portion in up to two indications is expected to follow the Phase 1a portion. Aclaris expects to complete the Phase 1a portion by year-end 2025 and provide top line results in early 2026, followed by top line results from the Phase 1b portion in the second half of 2026.

Corporate:
| ● | Strong Cash Runway Funds the Company’s Planned Operations into the Second Half of 2028: The Company is assessing potential non-dilutive opportunities to extend the cash runway further. |
| ● | Provided Update on Senior Leadership: Roland Kolbeck, Ph.D. has been appointed as Chief Scientific Officer, replacing Joe Monahan, Ph.D. who will remain with the Company as Special Scientific Advisor to the Chief Executive Officer through the first quarter of 2026 as part of his planned retirement.

Financial Results
Liquidity and Capital Resources
As of June 30, 2025, Aclaris had cash, cash equivalents and marketable securities of $180.9 million compared to $203.9 million as of December 31, 2024. The Company believes that its cash, cash equivalents and marketable securities will be sufficient to fund its operations into the second half of 2028, without giving effect to any potential business development transactions or financing activities.
Second Quarter 2025 and Year-to-Date 2025
Net loss was $15.4 million for the second quarter of 2025 compared to $11.0 million for the second quarter of 2024. Net loss was $30.5 million for the six months ended June 30, 2025 compared to $27.9 million for the six months ended June 30, 2024.
Total revenue was $1.8 million for the second quarter of 2025 compared to $2.8 million for the second quarter of 2024. Total revenue was $3.2 million for the six months ended June 30, 2025 compared to $5.2 million for the six months ended June 30, 2024. The decrease for both comparison periods was primarily driven by the sale of a portion of royalty payments under the Company’s agreement with Eli Lilly and Company to OCM IP Healthcare Portfolio IP, an investment vehicle for Ontario Municipal Employees Retirement System (OMERS), in July 2024.
Research and development (R&D) expenses were $11.4 million and $23.0 million for the quarter and six months ended June 30, 2025, respectively, compared to $8.8 million and $18.6 million for the corresponding prior year periods. The increases were primarily driven by product candidate manufacturing costs, preclinical development activities, and clinical development expenses associated with the Phase 2 trial in AD for bosakitug and the Phase 1a/1b program for ATI-052. For the six-month comparison period, clinical development expenses associated with the Phase 2a trial in AD for ATI-2138 also contributed to the increase. The increases were partially offset by a reduction in development expenses for zunsemetinib for both comparison periods.
General and administrative (G&A) expenses were $5.4 million for the quarter ended June 30, 2025 compared to $4.8 million for the corresponding prior year period. The increase was primarily driven by higher personnel expenses as a result of higher headcount. G&A expenses were $11.5 million for the six months ended June 30, 2025 compared to $11.6 million for the six months ended June 30, 2024. The decrease was primarily driven by lower personnel expenses as a result of lower termination benefits.
2
Revaluation of contingent consideration resulted in a $1.5 million charge for the quarter ended June 30, 2025 compared to a $0.2 million charge for the prior year period. The increase was primarily due to changes to the probability of success for certain product candidates and lower discount rates resulting from changes in credit spreads being applied to potential payments during the quarter ended June 30, 2025. For the six months ended June 30, 2025, revaluation of contingent consideration resulted in a charge of $1.8 million compared to $3.0 million for the prior year period. The decrease was primarily due to changes in estimated sales levels and changes to the probability of success for certain product candidates during the six months ended June 30, 2024.
