MENLO PARK, Calif., March 21, 2017 (GLOBE NEWSWIRE) — Dermira, Inc. (NASDAQ:DERM), a biopharmaceutical company dedicated to bringing biotech ingenuity to medical dermatology by delivering differentiated, new therapies to the millions of patients living with chronic skin conditions, today presented new information about the Axillary Sweating Daily Diary (ASDD), a proprietary patient-reported outcome (PRO) instrument designed to measure the sweating severity of axillary hyperhidrosis and its impact on daily activities and bothersomeness for patients. The presentation took place at the 13th Annual Maui Derm for Dermatologists 2017 meeting in Maui, Hawaii.
Hyperhidrosis is a condition of sweating beyond what is physiologically required for normal thermal regulation and affects an estimated 4.8% of the U.S. population, or approximately 15.3 million people. According to a published study, 65% of hyperhidrosis sufferers in the United States have axillary hyperhidrosis, and approximately half of those axillary hyperhidrosis sufferers, or 5.2 million Americans, have severe disease that is barely tolerable and frequently interferes or is intolerable and always interferes with daily activities.1 Other studies have further demonstrated that excessive sweating often impedes normal daily activities and can also result in occupational, emotional, psychological, social and physical impairment. 2,3
“Based on recent estimates, hyperhidrosis appears to be one of the more prevalent skin conditions in the general population,” said Eugene A. Bauer, M.D., chief medical officer of Dermira and a dermatologist. “We believe that the ASDD PRO represents an important new tool to enable clinicians to evaluate the impact a treatment for excessive sweating is having on the patient’s condition.”
Despite the high prevalence and impact of hyperhidrosis, few disease-specific measures which accurately assess patient outcomes exist. While the Hyperhidrosis Disease Severity Scale (HDSS) has been widely used in hyperhidrosis clinical studies for more than a decade, the U.S. Food and Drug Administration (FDA) determined that it does not conform to the agency’s standards for PRO measures that can be used to support a current product approval and labeling. 4,5
Dermira developed the ASDD instrument in accordance with the 2009 FDA guidance document for PRO instruments. The ASDD was drafted based on clinical expertise, literature review and feedback from the FDA. The ASDD was further refined based on qualitative interviews with adults and children (21 adults and 8 children). A child-specific version was developed (ASDD-C) for assessment of sweating severity in patients 16 years of age and younger.
The ASDD consists of four distinct items that ask patients various questions about their excessive sweating. Item 1 is a gating question that establishes a patient’s baseline sweating during a 24-hour period, Item 2 addresses sweating severity and Items 3 and 4 measure the impact of the excessive sweating on a patient’s daily activities and bothersomeness. Two additional sections of the instrument assess the weekly impact of the patient’s sweating (Item 5) and the overall impact of the patient’s sweating following treatment in a clinical study (Item 6).
The ASDD PRO instrument was first evaluated by Dermira during a Phase 2b clinical trial assessing the safety and efficacy of glycopyrronium tosylate (formerly DRM04) in 102 patients with primary axillary hyperhidrosis (excessive underarm sweating). The psychometric properties of ASDD Item 2 were validated using data generated from this Phase 2b trial and allowed this item to be used specifically as a key clinical endpoint to evaluate the effectiveness of treatment with glycopyrronium tosylate in Phase 3 studies.
As previously reported, in two Phase 3 trials, the glycopyrronium tosylate-treated patients experienced an improvement in their sweating severity compared to vehicle, as measured by ASDD, beginning at week 1 in ATMOS-1 (22.9% vs. 5.3%) and ATMOS-2 (29.0% vs. 4.2%), that continued through the completion of the 4-week treatment period.
About Glycopyrronium Tosylate
Glycopyrronium tosylate is formulated as a topical, once-daily anticholinergic agent that is currently in clinical development for the treatment of primary axillary hyperhidrosis. Glycopyrronium tosylate is designed to block sweat production by inhibiting the interaction between acetylcholine and the cholinergic receptors responsible for sweat gland activation. Dermira intends to submit a New Drug Application (NDA) to the FDA for glycopyrronium tosylate for the treatment of primary axillary hyperhidrosis in the second half of 2017, subject to the completion of registration-enabling activities.
