Treatment of Type 2 Diabetes Using Meal-Triggered Gastric Electrical Stimulation


    Background: The TANTALUS System (MetaCure Ltd.) is a minimally invasive implantable device for the treatment of type 2 diabetes. The system detects food intake by sensing gastric electrical variations and applies electrical stimulation to the gut synchronized to natural gastric activity. The system is commercially available in Europe and Israel and is in clinical trials in the United States. It has been tested in 132 patients worldwide to date.

    Objectives: To re-analyze previously reported data from different studies. This retrospective analysis of the type 2 diabetes subpopulation analyzed the expected benefit and characterize the significance of baseline A1c in the determination of the expected clinical outcome.

    Methods: From the total cohort of 132 patients implanted with the TANTALUS device in 10 different centers in Europe and the U.S., 50 subjects (27 females, 23 males) who were obese with uncontrolled T2DM[1] on a stable regime of oral medication for 3 months prior to implant were identified. This population had similar inclusion/exclusion criteria as well as treatment protocols and were all treated for at least 24 weeks. The analysis was based on the A1c change compared to baseline.

    Results: Data after 24 weeks demonstrate a reduction in A1c in 80% of the patients with average drop in A1c of 1.1 ± 0.1%. The average weight loss was 5.5 ± 0.7 kg.

    Conclusions: The results suggest that the TANTALUS stimulation regime can improve glucose levels and induce moderate weight loss in obese T2DM patients.
