Study Overview
Brief Summary
This is a prospective, multi-center, parallel, randomized, blinded study. The study has two groups, where in one study group the subjects receive treatment for axillary hyperhidrosis (excessive underarm sweating) with the DTS-G2 System in both axilla ("treatment group"). The other study group receives a sham treatment in both axilla where the subjects will have the same procedure performed but no energy from the device will be applied ("sham group"). Subjects will be randomized in a 2:1 ratio (treatment group: sham group).
Subjects enrolled in the study will be blinded regarding which study group they are in. The study hypothesis is that subjects that receive the treatment will have a reduction in underarm sweating compared to those in the sham group, as measured by a quality of life questionnaire.
All subjects will undergo follow up assessments at 14 days, 30 days, 3 months and 6 months post final treatment session. Subjects randomized to the treatment group will also have follow-up visits at 9 months and 12 months post final treatment session.

Arms & Interventions
Treatment with DTS-G2 System
Subjects receive treatment with the DTS-G2 System (an energy-based medical device) in both axilla. Multiple treatment sessions may be used.
Intervention: DTS-G2 System (Device)
Sham treatment
All elements of the treatment are given except that no energy is delivered. Multiple treatment sessions may be used.
Intervention: DTS System (Sham treatment) (Device)
Outcomes
Primary Outcomes
Percentage of Subjects That Report an HDSS Score of 1 or 2 at 30 Days.
Time Frame: 30 days post-treatment
The Hyperhidrosis Disease Severity Scale (HDSS) is a validated scale for measuring the effect of excessive sweating on the quality of life. It is a 4-point scale, with the following descriptors: 1. - My underarm sweating is never noticeable and never interferes with my daily activities 2. - My underarm sweating is tolerable but sometimes interferes with my daily activities 3. - My underarm sweating is barely tolerable and frequently interferes with my daily activities 4. - My underarm sweating is intolerable and always interferes with my daily activities
Secondary Outcomes
- Percentage of Subjects That Report an HDSS Score of 1 or 2 at the 6 Month Follow-up Visit.(6 months post-treatment)
- Percentage of Treatment Group Subjects That Report an HDSS Score of 1 or 2 at the 12 Month Visit(12 months)
- Percentage of Subjects With Reported Adverse Events(6 months post-treatment)
