A Safety Study of BBI-4000 Gel in Pediatric Patients With Axillary Hyperhidrosis
A Multi-Center Open-Label Extension Study to Assess the Long-Term Safety Tolerability and Pharmacokinetics of Sofpironium Bromide Gel 15% Applied Topically to Children and Adolescents Age 9-17 Years Previously Enrolled in BBI-4000-CL-105

Detailed Description
This is an open-label, phase 2 long-term study designed to evaluate the safety, local tolerability, pharmacokinetics and efficacy of sofpironium bromide gel when applied topically to the axillae.
Subjects will apply the gel once daily at bedtime, to both axillae.
A maximum of 24 subjects, will be enrolled to receive sofpironium bromide gel, 15%.
Adverse events, vital signs, and local tolerability assessments will be collected at each visit. 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 pharmacokinetics, 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 8 scheduled visits to take place over a 26 week period.

Description
Inclusion Criteria:
- Male or female subject ≥9 to <17 years of age in good general health.
- Diagnosis of primary axillary hyperhidrosis that meets all the following criteria: (a) HDSM-Ax of 2 - 4 inclusive at both the Screening Visit (Visit 1) and Baseline Visit (Visit 2). (b) Symptoms of axillary hyperhidrosis for greater than or equal to 6 months' duration prior to enrollment.
Exclusion Criteria:
- In the Investigator's opinion, any skin or subcutaneous tissue conditions of the axilla(e), (i.e., the axillary area should be deemed otherwise "normal", besides the hyperhidrosis diagnosis, and free of blisters, large boils or sinus tracts, significant scarring or open wounds).
- Prior use of any prohibited medication(s) or procedure(s) within the specified timeframe for the treatment of axillary hyperhidrosis: (a) Botulinum toxin to the axillary area within 9 months of enrollment. (b) Axillary thermolysis, sympathectomy or surgical procedures of the axillary area at any time in the past. (c) Serotonergic agonist (or drugs that increase serotonin activity including SSRIs), beta-blocker, alpha-adrenergic agonist (clonidine), dopamine partial agonist or tricyclic antidepressant treatment within 30 days of enrollment. However, if a subject has been on a stable dose (in the opinion of the PI) of any of these medications and has not had a recent change in hyperhidrosis frequency or severity for 3 months prior to enrollment; they may be included. Doses of these agents should not be altered during the course of the study. (d) Any topical treatment for hyperhidrosis, requiring a prescription, within 3 days of enrollment.
- Anticholinergic agents [with the exception of sofpironium bromide] used to treat conditions such as, but not limited to, hyperhidrosis, asthma, incontinence, gastrointestinal cramps, and muscular spasms by any route of administration (e.g., IV, oral, inhaled, topical) within 30 days of the enrollment.
- Use of potent oral inhibitors of cytochrome P450 CYP3A & CYP2D6 and transporter inhibitors (OCT2/MATE1/MATE2) 14 days prior to enrollment. The use of topical antifungal medications is permitted if not applied in the treatment area.
- Any oral or topical homeopathic or herbal treatment (i.e., alternative therapies such as sage tablets, chamomile, valerian root and St. John's Wort) within 14 days of enrollment.
- Use of any cholinergic drug (e.g., bethanechol) within 30 days of enrollment.
- Use of any anti-anxiety and/or anti-depressant, amphetamine product or drugs with known anticholinergic side effects is prohibited with the following exceptions: (a) If a subject has been on a stable dose of an anti-anxiety and/or anti-depressant drug and has not had a recent change in hyperhidrosis frequency or severity for 3 months; they may be included. (b) An amphetamine product may be allowed if the dose has been stable for greater than or equal to 6 months without change in hyperhidrosis frequency or severity for 3 months. (c) Drugs with known anticholinergic side effects (taken within the last 30 days), including dry mouth, blurred vision, may be allowed based on the Principal Investigator's assessment.
- Known causes 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 hyperhidrosis symptoms initiated or exacerbated with menopause.
- Subjects with unstable type 1 or type 2 diabetes mellitus or thyroid disease, history of renal impairment, hepatic impairment, malignancy, glaucoma, intestinal obstructive or motility disease, obstructive uropathy, myasthenia gravis, benign prostatic hyperplasia (BPH), neurological conditions, psychiatric conditions, Sjögren's syndrome, Sicca syndrome, or cardiac abnormalities that may alter normal sweat production or may be exacerbated by the use of anticholinergics in the Investigator's opinion.
- Known hypersensitivity to glycopyrrolate, anticholinergics, or any of the components of the topical formulation.
- Subject is pregnant, lactating or is planning to become pregnant during the study.
- Unable or unwilling to undergo multiple venipunctures.
