CompletedPhase 3

Safety and Efficacy Study of Sofpironium Bromide in Subjects With Axillary Hyperhidrosis (BBI-4000-CL-301)

United States350 participantsStarted 2020-10-09

Plain-language 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.

Inclusion Criteria: * Male or female subject ≥ 9 years of age. * Diagnosis of primary axillary hyperhidrosis that meets the following criteria: (a) symptoms of hyperhidrosis for at least 6 months' duration, (b) HDSM-Ax of 3 - 4 and (c) a minimum GSP of 50 mg in each axilla with a combined total of at least 150 mg. * The ability to understand and follow all study-related procedures including study drug administration. * Sexually active female of childbearing potential (FOCBP)\* must agree to periodic pregnancy testing and use a medically acceptable method of contraception while receiving protocol-assigned product. Exclusion Criteria: * In the Investigators opinion, any skin or subcutaneous tissue conditions of the axilla(e). * Prior use of any prohibited medication(s) or procedure(s) within the specified timeframe for the treatment of axillary hyperhidrosis. * Anticholinergic agents used to treat conditions such as, but not limited to, hyperhidrosis, asthma, incontinence, gastrointestinal cramps, and muscular spasms by any route of administration. * Use of any cholinergic drug (e.g. bethanechol) within 28 days. * Known cause of hyperhidrosis or known history of a condition that may cause hyperhidrosis (i.e., hyperhidrosis secondary to any known cause such hyperthyroidism, diabetes mellitus, medications, etc.). * Subjects with unstable diabetes mellitus or thyroid disease, history of renal or hepatic impairment, malignancy glaucoma, intestinal obstructive or motility disease…

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
