WAYNE, Pa., June 28, 2018 (GLOBE NEWSWIRE) -- Aclaris Therapeutics, Inc. (NASDAQ:ACRS), a dermatologist-led biopharmaceutical company committed to identifying, developing, and commercializing innovative therapies to address significant unmet needs in aesthetic and medical dermatology and immunology, today announced positive interim data from its Phase 2 clinical trial (AA-202 Topical) of ATI-502 for the treatment of Alopecia Totalis (AT) or Alopecia Universalis (AU), the more severe variants of Alopecia Areata (AA). ATI-502, an investigational topical Janus Kinase (JAK) 1/3 inhibitor (ATI-502) is the most advanced topical JAK inhibitor in clinical trials for AT/AU in the United States. This randomized, double-blind clinical trial is being conducted at 2 study sites and will evaluate the pharmacokinetics, pharmacodynamics and safety of ATI-502 compared with vehicle in 11 patients with AT or AU over 28 days of treatment, followed by a 6-month open label period when all patients receive the drug.
AA is an autoimmune dermatologic condition typically characterized by patchy non-scarring hair loss on the scalp and body. More severe forms of AA are characterized by a total scalp hair loss (AT) or total hair loss on the scalp and body (AU). Today, we report interim results for 6 of the 11 enrolled patients; data from the full cohort will be reported in the future.

Key Results Summary
This data is the first indication that ATI-502 is absorbed through human skin in the clinical setting and engages the target. The results also demonstrate the pharmacodynamic effect of modulating the appropriate genes associated with the interferon gamma pathway and cytotoxic T-lymphocytes, which are 2 of 3 biomarker components of the Alopecia Areata Disease Activity Index (ALADIN) score. Our hypothesis is this response can be predicted by a patient’s baseline genetic signature.
“This is the first time we have demonstrated that Topical ATI-502 is positively impacting the genetic signature implicated in alopecia areata,” said Stuart Shanler, M.D., Chief Scientific Officer of Aclaris Therapeutics, Inc.

About Alopecia Areata
Alopecia areata is an autoimmune disease that results in partial or complete loss of hair on the scalp and body. The scalp is the most commonly affected area, but any hair-bearing site can be affected alone or together with the scalp. Onset of the disease can occur throughout life and affects both women and men. AA can be associated with serious psychological consequences, including anxiety and depression. AA affects up to 2.0% of people globally at some point during their lifetime (i.e. incidence) and up to 0.2% of people are affected at any given time (i.e. prevalence). There are currently no drugs approved by the FDA for the treatment of AA.
