45% Concentration A-101 Topical Solution Achieved Primary and Secondary Endpoints
MALVERN, PA, USA I August 18, 2016 I Aclaris Therapeutics, Inc. (NASDAQ:ACRS), a clinical-stage specialty pharmaceutical company, today announced positive results from its Phase 2 clinical trial (WART-201), of A-101 Topical solution (A-101) for the treatment of common warts (verruca vulgaris). A-101 is a proprietary formulation of high-concentration hydrogen peroxide currently under development as a prescription treatment for common warts.
WART-201 was a randomized, double-blind, vehicle-controlled, clinical trial designed to evaluate the safety and dose-response of 2 concentrations of A-101 Topical solution, 40% and 45%, compared with placebo (vehicle) in patients with common warts. Ninety-eight patients were enrolled in the study with 90 patients completing eight weekly treatments at six investigational centers within the United States.
In the trial, the 45% concentration of A-101 demonstrated clinically relevant and statistically significant improvement in the mean change in the Physician’s Wart Assessment (PWA) score and in complete clearance of common warts. The side effect profile was similar to placebo.
WART-201 Efficacy Results:
- The primary endpoint was the mean change from baseline in the PWA score one week after the last treatment. Patients treated with 45% concentration A-101 demonstrated a statistically significant change in PWA score versus placebo (p=0.01).
- The secondary endpoints included two responder analyses: the proportion of patients whose target wart was judged to be clear on the PWA scale; and the proportion of patients whose target wart was judged to be either clear or barely evident on the PWA scale.
- A-101 45% Topical solution achieved statistically significant complete clearance of the target wart one week after the last treatment versus placebo (p=0.02).
- The proportion of target warts treated with A-101 45% Topical solution achieving a score of clear or barely evident one week after the last treatment was also statistically significant versus placebo (p=0.02).
WART-201 Safety Results:
- A-101 was well-tolerated and local skin reactions (LSR) were primarily mild in severity and similar to placebo. The most frequently reported LSR across treatment groups was mild erythema.
“We are extremely pleased with these results,” said Dr. Neal Walker, President & CEO of Aclaris. “This is an important milestone for our A-101 development program and substantiates the clinical value of our proprietary formulation of A-101 Topical solution. Based on these results, we plan to continue the development of the 45% concentration of A-101 as a potential treatment for common warts.”
About Common Warts (Verruca Vulgaris)
Warts are benign skin growths which appear when human papillomavirus (HPV) infects the top layer of the skin. On an annual basis, 1.9 million people are diagnosed with common warts and although the warts are generally not harmful and in most cases eventually clear without any medical treatment, they may be painful, aesthetically unattractive, and are contagious. Common warts can be removed with slow-acting, over-the-counter products containing salicylic acid. Cryosurgery is the most frequently used in-office treatment for common warts. No prescription drugs have been approved by the FDA for the treatment of common warts.
