Clinical Trial Summary

Hyperhidrosis is a disorder of abnormal excessive sweating. Primary hyperhidrosis (armpits, hands, and feet) affects approximately 4.8% of the US population and is believed to be caused by an overactive cholinergic response of the sweat glands. Current therapies have limited effectiveness, significant side effects, and can be invasive and costly. Sofpironium bromide (BBI-4000) is a novel soft-drug in development for the topical treatment of hyperhidrosis. This Phase 3 study will assess the safety and efficacy of sofpironium bromide, 15% gel versus vehicle (2 treatment arms), applied for the treatment of axillary hyperhidrosis.

Description:

This is a multicenter, randomized, double-blind, vehicle-controlled study to evaluate the safety and efficacy of topically applied sofpironium bromide, 15% gel in subjects with axillary hyperhidrosis. Safety will be assessed through collection of vital signs, adverse events, local skin responses, hematology, serum chemistry laboratory testing and urinalysis. A maximum of 350 subjects will be randomized to receive either sofpironium bromide gel, 15% or vehicle. Adverse events, vital signs, and local tolerability assessments will be collected at visits across the study. Urine pregnancy tests will be taken throughout the course of the study for women of child bearing potential. Blood and urine samples will be collected and analyzed for routine hematology, chemistry, and urinalysis parameters at specified visits. Patient-reported outcome assessments will be recorded during the study at predefined time points. The study will be comprised of a total of 13 scheduled visits to take place over approximately 11 to 15 weeks.

Eligibility

Inclusion Criteria:

• Male or female subject = 9 years of age.
• Diagnosis of primary axillary hyperhidrosis that meets the following criteria: (a) symptoms of hyperhydrosis for at least 6 months' duration, (b) HDSM-Ax of 3 - 4 and (c) a minimum GSP of 50 mg is each axilla with a combined total of at least 150 mg.
