Safety and Effectiveness of Transcutaneous Electrical Nerve Stimulation (TENS)-Assisted Weight Loss

This study employs a randomized, adaptive, parallel arm study in which, cohorts of enrolled subjects (25 per arm) are assessed for dose response and progression to achievement of primary and secondary endpoints. Enrollment will be up to 300 subjects at 4 US centers. After signing informed consent, subjects will be screened during a one week screening/baseline period to determine if they meet the inclusion criteria and exhibit none of the exclusion criteria. Weight, blood pressure, blood lipids, HgA1c, pregnancy test (for women of childbearing age), and patient questionnaires will be collected. If eligible, subjects will be randomized to treatment or control groups. The treatment group will receive training on the Elira Wearable Patch System and the first TENS session will be administered in the investigators office. Both groups will receive an electronic scale and instructions on 1200 calorie diet as well as diary completion requirements to be completed throughout the study. All subjects will be required to have in office follow-up visits every 4 weeks for 12 weeks. Up to 2 additional follow-up visits will be permitted within that 12 week time period.
