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

Elira Therapeutics, Inc.77 enrolled

Overview

This study is a randomized, adaptive, parallel arm study. The treatment group will receive the Elira wearable patch system and provided instructions for use and advised to follow a 1200 calorie diet. The control group will be asked to follow a 12 calorie diet only. Each group will be followed for 12 weeks. Total body weight loss will be measured as well as appetite changes. Safety data will be collected throughout the study period. Safety and effectiveness will be determined based on differences between the groups.

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.

Transcutaneous Nerve Stimulator (TENS)DEVICE

The Elira wearable patch system is a RF coupled, wearable transcutaneous electrical nerve stimulator (TENS) device controlled via Bluetooth by a smart phone unit running a custom application which directs therapy from the patch within safe limits set by a clinician and also includes a weight loss diary.

Outcomes

Primary Outcomes

Treatment Emergent Adverse Events

Safety/Tolerability will be assessed by the non-inferiority of incidence of serious adverse events (SAEs), unanticipated DAEs (USAEs), device-related SAEs (DSAEs), and unanticipated device-related SAEs (UDAEs) that are associated with the TENS therapy throughout the stimulation and the follow-up period versus historical control (compared with other TENS systems).
