- Top-line Data Anticipated Around Year End
WAYNE, Pa., Oct. 03, 2023 (GLOBE NEWSWIRE) -- Aclaris Therapeutics, Inc. (NASDAQ: ACRS), a clinical-stage biopharmaceutical company focused on developing novel drug candidates for immuno-inflammatory diseases, today announced the completion of enrollment into ATI-1777-AD-202, its Phase 2b trial of its investigational topical “soft” Janus kinase (JAK) 1/3 inhibitor, ATI-1777, in patients with mild to severe atopic dermatitis. Aclaris anticipates releasing top-line efficacy, safety and other preliminary data from this trial around the end of this year.
“We are very pleased to have completed the enrollment stage of our Phase 2b trial of ATI-1777 in atopic dermatitis, one of our two lead clinical development assets,” stated Gail Cawkwell, M.D., Ph.D., Aclaris’ Chief Medical Officer. “With this achievement, we are positioned for a very exciting year end for our two lead assets, first with the data read-out of our Phase 2b trial of zunsemetinib (ATI-450) in rheumatoid arthritis expected in November, followed by the top-line results of the ATI-1777 trial expected around year end.”
ATI-1777 is a topical JAK inhibitor designed to minimize systemic exposure and delivered in a spray-on solution. The Phase 2b trial follows the successful four-week Phase 2a trial in moderate to severe atopic dermatitis which demonstrated meaningful improvement in the modified Eczema Area and Severity Index (EASI) and minimal measurable systemic exposure with a 2% formulation applied twice daily. The Phase 2b vehicle-controlled trial in atopic dermatitis further explores the concentration range (0.5%, 1% and 2%), as well as a once-daily regimen using the 2% formulation. The trial enrolled 250 patients with mild, moderate or severe AD, including adults and children as young as 12-years-old, across 34 clinical trial sites in the U.S. The primary efficacy endpoint is the percent change in EASI over a period of 4 weeks. Secondary measures of efficacy, as well as safety and pharmacokinetics, will also be assessed.
