Subjects receive treatment with the DTS-G2 System (an energy-based medical device) in both axilla. Multiple treatment sessions may be used.
All elements of the treatment are given except that no energy is delivered. Multiple treatment sessions may be used.
Outcomes
Primary Outcome Measures
Percentage of Subjects That Report an HDSS Score of 1 or 2 at 30 Days.
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:
- My underarm sweating is never noticeable and never interferes with my daily activities
- My underarm sweating is tolerable but sometimes interferes with my daily activities
- My underarm sweating is barely tolerable and frequently interferes with my daily activities
- My underarm sweating is intolerable and always interferes with my daily activities
Secondary Outcome Measures
Percentage of Subjects That Report an HDSS Score of 1 or 2 at the 6 Month Follow-up Visit.

- My underarm sweating is barely tolerable and frequently interferes with my daily activities
- My underarm sweating is intolerable and always interferes with my daily activities
Percentage of Treatment Group Subjects That Report an HDSS Score of 1 or 2 at the 12 Month Visit
The Hyperhidrosis Disease Severity Scale (HDSS) is a 4-point validated scale for measuring the effect of excessive sweating.
- My underarm sweating is never noticeable and never interferes with my daily activities
- My underarm sweating is tolerable but sometimes interferes with my daily activities
- My underarm sweating is barely tolerable and frequently interferes with my daily activities
- My underarm sweating is intolerable and always interferes with my daily activities This outcome is only measured for the treatment group; sham group exited the study after 6 month visit.
Percentage of Subjects With Reported Adverse Events
Adverse events were defined in the protocol and included anticipated side effects of the procedure. These events were tracked by the clinical site and did include subject-reported events. The events reported here only included side effects that were attributed by the principal investigator as being possibly to definitely related to the device or procedure. They did not include expected treatment effects, such as swelling or bruising in the treatment area.

5. Study Description
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.
