WAYNE, Pa., Dec. 17, 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 dermatology, both aesthetic and medical, and immunology, today provided updated data from three clinical trials for ATI-502, an investigational topical Janus kinase (JAK) 1/3 inhibitor, an update on the expected release of topline data for one clinical trial for ATI-502, and an enrollment update for a clinical trial for ATI-501, an investigational oral JAK 1/3 inhibitor.
AA-202 Topical and AUATB-201 Topical are ongoing Phase 2 clinical trials of ATI-502 for the treatment of alopecia areata (AA) in the United States and Australia, respectively. In AA-202 Topical, 11 patients with the more severe forms of AA, alopecia universalis (AU) and alopecia totalis (AT), were treated with ATI-502 in an initial double-blind pharmacokinetic and pharmacodynamic study for 28 days before entering a 12-month open-label extension. In AUATB-201 Topical, an open-label clinical trial, 12 patients with eyebrow loss due to AA, including patients with AU or AT, had their eyebrows treated with ATI-502 for 6 months. VITI-201 Topical is an open-label pilot clinical trial of ATI-502 administered twice daily in 34 patients with non-segmental facial vitiligo.
As announced in November, Aclaris completed enrollment of AA-201 Topical, a randomized, double-blinded, parallel-group, placebo-controlled trial to evaluate the safety, efficacy and dose response of two concentrations of ATI-502 for the treatment of AA. This trial enrolled 129 patients with patchy AA, who were randomized to receive either ATI-502 or placebo. The primary efficacy endpoint is the mean change from baseline in the Severity of Alopecia Tool (SALT) score at Week 24. Topline data from the AA-201 Topical trial are now expected in the second quarter of 2019.
In addition, Aclaris announced today that it has completed enrollment of AUAT-201 Oral, a randomized, double-blinded, parallel-group, placebo-controlled trial to evaluate the safety, efficacy and dose response of three concentrations of ATI-501 oral suspension for the treatment of AA. This trial enrolled 87 patients with AA, including AT and AU, who were randomized to receive either ATI-501 or placebo. The primary efficacy endpoint is the mean change from baseline in the SALT score at Week 24. Topline data from the AUAT-201 Oral trial are now expected in the third quarter of 2019.
“AA can be a psychologically devastating disease for which many patients do not have adequate options for treatment. Inhibition of the JAK1 and JAK3 pathways is an emerging therapeutic approach. We continue to advance our development programs for oral and topical formulations of JAK inhibitors with the goal of addressing the full spectrum of disease severity for patients living with AA,” said Dr. David Gordon, Chief Medical Officer of Aclaris.
