Aclaris Therapeutics Reports Second Quarter 2026 Financial Results and Provides Corporate and Clinical Update
Rhea-AI Summary
Aclaris Therapeutics (NASDAQ: ACRS) reported second quarter 2026 net loss of $21.5 million versus $15.4 million a year earlier on total revenue of $1.6 million versus $1.8 million. R&D rose to $18.1 million, driven mainly by ATI-052 and ATI-9494 development, while G&A increased to $6.0 million.
Cash, cash equivalents and marketable securities were $170.6 million at June 30, 2026, up from $151.4 million at year-end 2025. After quarter-end, Aclaris raised $40.2 million gross via sale of 7.3 million shares under its ATM, and now expects its cash to fund operations through end of 2028. Clinically, full Phase 1a SAD/MAD data for bispecific antibody ATI-052 showed a favorable safety profile and PK/PD supporting potential quarterly dosing, and timelines were reaffirmed for 2026 readouts from two Phase 1b POC trials of ATI-052 and a Phase 2 trial of anti-TSLP antibody bosakitug (ATI-045).

An at-the-market arrangement lets an issuer sell new shares gradually in the open market at prevailing prices rather than through one single priced deal.
The company says the proceeds will support planned startup activities for the Phase 2b ATI-052 atopic-dermatitis trial and an eosinophilic-esophagitis proof-of-concept trial.

WAYNE, Pa., Aug. 06, 2026 (GLOBE NEWSWIRE) -- 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 2026 and provided a corporate and clinical update.
“The first half of 2026 was a period of strong execution across the organization, positioning Aclaris for an exciting second half of the year with numerous expected key catalysts,” stated Dr. Neal Walker, Chief Executive Officer and Chair of the Board of Directors of Aclaris. “We expect to provide three clinical data readouts, including placebo-controlled top line results from our two Phase 1b POC trials of our anti-TSLP/IL-4Rα bispecific antibody ATI-052 in both asthma and atopic dermatitis and the Phase 2 AD trial of our anti-TSLP monoclonal antibody bosakitug. Other key catalysts include initiation of a Phase 2b clinical program with ATI-052 and a Phase 2b trial in lichen planus with modzatinib. Finally, our data presented recently at the FASEB Immunoreceptors and Immunotherapy conference support the best-in-class potential of our investigational ITK inhibitor ATI-9494, for which we expect to file an IND late this year.”
Second Quarter 2026 Highlights, Recent Updates and Upcoming Catalysts
Pipeline:
Biologics: Antibody Franchise
- Provided Positive Full Top Line Results of Phase 1a Single (SAD) and Multiple Ascending Dose (MAD) Trial of Investigational Bispecific Anti-TSLP/IL-4Rα Antibody ATI-052 Validating Potency and Potential for Extended Dosing: ATI-052 was well tolerated and demonstrated a favorable safety profile. The combination of the strong and sustained PK duration and PD effect supported the potential for up to quarterly dosing. (press release here)
- Reaffirmed Expectation of Top Line Results in the Second Half of 2026 from Two Ongoing Phase 1b POC Trials of ATI-052: ATI-052 is being assessed in POC trials in both atopic dermatitis (AD) and asthma.
- Confirmed Intent to Initiate a Phase 2b Program Encompassing Asthma and AD with ATI-052 in the Fourth Quarter of 2026: Aclaris expects the clinical program to commence with a Phase 2b trial in asthma in the fourth quarter of 2026. The Company also now expects to commence startup activities for a Phase 2b trial in AD and for a proof-of-concept (POC) trial in eosinophilic esophagitis (EoE).
- On Track for Expected Fourth Quarter 2026 Readout of Top Line Results from Phase 2 Trial of Investigational Anti-TSLP Monoclonal Antibody Bosakitug: Enrollment is complete in this randomized, double-blind, placebo-controlled Phase 2 trial designed to evaluate bosakitug in 109 patients with AD. (press release here)
Kinase Inhibitors: ITK Franchise
- Initiation of Phase 2b Clinical Program for Modzatinib (ATI-2138), a Potent and Selective Investigational Inhibitor of ITK and JAK3, Planned for the Fourth Quarter of 2026: Aclaris intends to initiate a multi-part Phase 2b trial of modzatinib in lichen planus, an unaddressed chronic, inflammatory, CD8-driven interface dermatitis. There are currently no approved therapies in this indication. (press release here)
- On Track for Expected Fourth Quarter 2026 Filing of Investigational New Drug (IND) Application for ATI-9494, Aclaris’ Investigational Dual Inhibitor of ITK and TXK: ATI-9494 has demonstrated potent blockade of Th1 and Th2 responses, a prolonged half-life, and high potency against ITK, potentially enabling low drug burden, dosing flexibility, and once daily (QD) administration across a broad range of disease indications.
- Presented Data Characterizing Potency, Selectivity, and Target Occupancy of ATI-9494: New preclinical data presented at the 2026 Federation of American Societies for Experimental Biology (FASEB) Immunoreceptors and Immunology Science Research Conference included results from cellular target engagement studies that demonstrated potent engagement of ITK by ATI-9494 and its ability to block functional activation of the TCR pathway. ATI-9494 demonstrated potency up to 25 times greater than soquelitinib (CPI-818) across multiple biochemical and functional cellular assays.
