- People suffering from primary axillary hyperhidrosis (excessive underarm sweating beyond what is needed to maintain normal body temperature) report that the condition has a significant impact on their daily lives, often resulting in avoidance of social interactions and taking additional measures to manage their excessive sweating
- Patients treated with glycopyrronium tosylate in Phase 3 clinical trials reported greater improvements across several measures designed to evaluate the impact of the investigational treatment on excessive underarm sweating
At the start of the clinical trials, patients reported that their excessive sweating was highly burdensome, with many reporting that the condition resulted in them avoiding social interactions and taking additional measures to cope with the condition, such as changing their shirt and showering multiple times during the day. After four weeks of treatment with glycopyrronium tosylate, patients in both trials reported improvements in their sweating severity, rating their sweating as much better or moderately better compared to treatment with vehicle. In addition, patients treated with glycopyrronium tosylate topical wipes reported greater weekly average improvements on all items that measured the daily burden of disease associated with axillary hyperhidrosis. Collectively, these data suggest that if approved, glycopyrronium tosylate wipes would have the potential to reduce the burden of disease for patients with excessive underarm sweating.
“People suffering from hyperhidrosis cope not only with the symptoms of the condition, but with the intense stigma that comes with excessive, uncontrollable sweating, which can have a profound impact on their lives,” said
“Primary axillary hyperhidrosis has long been associated with a poor quality of life for patients, resulting in changes in social and physical behaviors and feelings of embarrassment,” said
The two Phase 3 clinical trials, ATMOS-1 and ATMOS-2, were designed to evaluate the safety and efficacy of glycopyrronium tosylate wipes in patients with primary axillary hyperhidrosis. In these trials, the impact of a patient’s excessive sweating and the impact of glycopyrronium tosylate treatment were measured using the Axillary Sweating Daily Diary (ASDD), a new patient reported outcomes (PRO) instrument that is part of a multi-faceted assessment tool called the Axillary Hyperhidrosis Patient Measures (AHPM). Despite the prevalence of hyperhidrosis, no validated disease-specific measures have assessed what impact a particular therapy has on a person’s quality of life following treatment.
The AHPM consists of:
- The Axillary Sweating Daily Diary (ASDD), the new patient-reported outcomes (PRO) instrument which includes four validated items that asked patients 16 years of age and older questions about their excessive sweating and its impact on their daily activities. The ASDD PRO was developed and validated in accordance with the
U.S. Food and Drug Administration2009 PRO Guidance. Of note, Item 2 of the ASDD PRO, which asked patients to assess sweating severity, was a co-primary endpoint in the Phase 3 clinical trials. The Axillary Sweating Daily Diary-Children, which consisted of two questions, was designed to assess sweating in patients between ages 9 and 16.
- The Weekly Impact Questionnaire that assessed the impact of a patient’s sweating over seven days using six distinct questions.
- The Patient Global Impression of Change, which asked the patient to rate his or her axillary sweating following study treatment.
Burden of Axillary Hyperhidrosis at Baseline Using a Patient-Reported Outcome Measure to Assess Impact on Activities and Bothersomeness (ATMOS-1 and ATMOS-2)
- More than 50% of patients who participated in ATMOS-1 and ATMOS-2 reported that their sweating at baseline was at least a 7 on an 11-point scale, where 0 represents no sweating and 10 represents worst possible sweating.
- The majority of patients who were ages 16 years and older reported being significantly impacted by their excessive sweating, with most having to avoid social interactions or take additional measures such as showering/bathing more than once a day or changing shirts during the day to manage their excessive sweating.
- More than 90% of patients in the trials reported that they were less confident because of, or embarrassed by, their excessive sweating. This finding is consistent with previous research highlighting the condition’s burden on people suffering from excessive sweating.
Patient-Reported Outcomes from Two Randomized, Double-Blind, Vehicle-Controlled Phase 3 Trials in Axillary Hyperhidrosis (ATMOS-1 and ATMOS-2)
- After four weeks, glycopyrronium tosylate-treated patients reported greater weekly average improvement on all ASDD items compared to patients who received vehicle.
- At the end of treatment period, fewer glycopyrronium tosylate-treated patients reported the occurrence of negative behaviors or feelings associated with their excessive underarm sweating, such as feeling the need to change a shirt during the day and feeling embarrassed or less confident when compared to patients receiving vehicle.
- Of the patients treated with glycopyrronium tosylate, 73.6% of the patients in ATMOS-1 and 80.4% of the patients in ATMOS-2 rated their excessive underarm sweating as much better or moderately better, compared with 38.2% and 40.6% of vehicle-treated patients in the trials, respectively, representing a two-fold improvement.
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. 1 Of these, 65 percent, or nearly 10 million people, suffer from sweating localized to the underarms (axillary disease). 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
About Glycopyrronium Tosylate
Glycopyrronium tosylate is a once-daily anticholinergic agent, administered as a topical wipe, which has completed a Phase 3 program 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.
