MALVERN, PA, USA I August 03, 2017 I Aclaris Therapeutics, Inc. (NASDAQ:ACRS), a dermatologist-led biopharmaceutical company focused on identifying, developing and commercializing innovative and differentiated therapies to address significant unmet needs in medical and aesthetic dermatology, today announced it has submitted a Marketing Authorization Application (MAA) with the Medicines Product Agency (MPA) in Sweden for its product candidate A-101 40% Topical Solution for the treatment of seborrheic keratosis. The MPA will act as the reference member state in this decentralized procedure for review of the MAA for potential marketing approval throughout Europe. If approved, A-101 40% Topical Solution would be available to be commercialized in 16 countries in the European Union.

Seborrheic keratosis (SK) lesions are common, non-cancerous skin lesions which can have a negative physical and emotional impact on patients because they may be perceived as cosmetically unattractive and associated with aging. Existing treatments are often painful, invasive and can have undesirable outcomes such as pigmentary changes or scarring. Fewer than 10% of people [in the United States] with SK lesions currently receive treatment.

Positive results from two pivotal Phase 3 trials – SEBK-301 and SEBK-302 – were reported in late 2016 and provide the clinical basis for this MAA submission. In these trials, A-101 40% Topical Solution (A-101 40%) met all primary and secondary endpoints, achieving clinically and statistically significant clearance of SK lesions. The two trials, which were identical in design and together enrolled 937 patients, evaluated the safety and efficacy of A-101 compared with vehicle (placebo) in patients with four target SK lesions on the face, trunk, and extremities.

“This MAA submission represents a major step toward our goal of delivering a novel, topical treatment to address a significant unmet need in the dermatology market,” said Dr. Neal Walker, President and Chief Executive Officer of Aclaris. “If approved, we believe A-101 will have broad appeal across aesthetic and medical dermatology patients – both men and women.”

About A-101
A-101 40%, an investigational drug, is a proprietary, high-concentration hydrogen peroxide formulation for the treatment of SK. It is being developed as a non-invasive, in-office treatment administered by physicians or other licensed health care professionals. In clinical trials, patients treated with A-101 40% achieved statistically and clinically significant improvement in clearing SK lesions compared to placebo and with a similar adverse event profile. A-101 40% is designed to work by penetrating into the SK lesion and causing oxidative damage, which can ultimately result in the sloughing of the SK cells. A-101 40% has been the focus of a robust clinical development program in which over 700 patients have been treated with A-101. The 45% concentration of A-101 is also in clinical development for the treatment of common warts (verruca vulgaris).

About Seborrheic Keratosis
Seborrheic keratosis (SK) is a skin condition that affects more than 83 million Americans [and 28 million Europeans] and is characterized by non-cancerous lesions varying in color from light tan to dark brown or black. SK lesions range in size from a millimeter to a few centimeters wide and usually have a slightly elevated, waxy, scaly appearance. People with SK may be affected with just one lesion or dozens and often have a family history of SK. SK lesions can appear anywhere on the body, except the palms, soles, and mucous membranes, and frequently appear in highly visible locations, such as the face or neck. Though the lesions usually do not cause physical discomfort, SK can adversely affect the appearance and emotional well-being of people who have it. Prevalence of SK increases with advancing age and the majority of patients seeking treatment from dermatologists are between 40 and 70 years of age. Fewer than 10% of people [in the United States] with SK receive treatment, though it is one of the most frequent diagnoses made by dermatologists. There are currently no approved medications for SK [in the United States or Europe], and existing treatment procedures are often painful or invasive and can have undesirable outcomes like scarring or dyspigmentation.
