BACKGROUND: Primary axillary hyperhidrosis (PAHH) strongly affects the patient's quality of life. To date, topical treatment options are limited. One percent glycopyrronium bromide (GPB) showed promising efficacy and safety in a pivotal 4-week Phase 3a study.
OBJECTIVES: To assess efficacy and safety of topical 1% GPB cream in patients with severe PAHH in a long-term study of 72 weeks versus baseline.
METHODS: This was a long-term, open-label, Phase 3b trial for 72 weeks including 518 patients with severe PAHH. Patients were treated with 1% GPB cream once daily for 4 weeks, followed by a flexible dosing scheme (min. twice per week, max. once daily). Primary endpoint was the absolute change in sweat production from baseline to week 12. Further study endpoints included assessment of the severity of PAHH and the impact on quality of life.
RESULTS: Total median sweat production decreased by 119.30 mg (-65.6%, both median) until week 12. Absolute change in sweat production from baseline to week 12 in logarithmic values was statistically significant (p < 0.0001). Patients' quality of life was improved at all study time points compared to baseline, as assessed by Hyperhidrosis Quality of Life Index and Dermatology Life Quality Index (p < 0.0001). Treatment was safe and locally well-tolerated with only few mild to moderate adverse drug reactions (ADRs). Dry mouth and application site erythema were the most common reported ADRs.
CONCLUSIONS: Treatment with 1% GPB cream over 72 weeks significantly reduces sweat production and improves quality of life in patients with severe PAHH. One percent GPB cream is well-tolerated and provides an effective treatment option for long-term use in patients with severe PAHH.
