Single-Treatment, Study of Percutaneous-Temperature Controlled-RF Electrocoagulation on Axilla Tissue

This is a pilot, open-label, and single-center, single-treatment prospective evaluation of the electrocoagulation of axillary sweat gland tissue using the ThermiRF device to alleviate or improve symptoms associated with axillary sweating.

In this study, "Temporary Relief" is defined as improvement on the DLQI.

A total of 20 male and female healthy volunteers between the age of 18 and 50 will be enrolled in this study. Subjects who sign the informed consent form and meet all entry criteria will be assigned a unique number/code to preserve confidentiality.

A total of five visits are planned for this study as described below:

• Visit 1: Screening visit - (Day 0)
• Visit 2: Single Treatment
• Visit 3: Day 30 (± 7 days)
• Visit 4: Day 60 (± 7 days)
• Visit 5: Day 90 (± 7 days)

A punch biopsy will be collected at Visit 1(screening), Visit 2 (post-treatment) and Visit 4 (Day 60). The purpose of the punch biopsy is to evaluate the degree of impact to the axillary organ after the electrocoagulation treatment when compared to pre-treatment at Visit 1.

Safety assessments will be collected using the Numerical Rating Scale (NRS) a 10-point scale, and adverse events reports (observed or reported).

The total length of the study is approximately 4 months.
