NCT ID: NCT02633371

Last Updated: 2018-06-19

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: NA
• Total Enrollment: 10 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2016-02-29
• Study Completion Date: 2017-05-31

Brief Summary

This is a single-center, prospective, open-label, outpatient pilot study evaluating the efficacy and tolerability of oxybutynin gel for axillary hyperhidrosis.

Detailed Description

This study will determine if daily application of topical oxybutynin 3% gel reduces the symptoms of primary axillary hyperhidrosis in adolescents and young adults. It will also assess the impact of daily topical oxybutynin 3% gel on Health Related Quality of Life (HRQOL); determine if daily topical oxybutynin 3% gel has a treatment effect at distant, untreated sites; and assess the local and systemic tolerability of daily topical oxybutynin 3% gel. Finally, the study will determine the treatment effect size, if one exists, in order to power a larger, placebo-controlled study in the future.

• Subjects who have demonstrated hypersensitivity to the drug substance or other components of the product
• Subjects taking drugs which inhibit Cytochrome P450 3A4 (CYP3A4)
