Description

Summary

The Revita® system is being investigated to assess the efficacy of DMR versus Sham on improvement in Glycemic, Hepatic and Cardiovascular endpoints for patients with Type 2 Diabetes who are inadequately controlled with insulin therapy. The purpose of this study is to demonstrate the efficacy and safety of the Fractyl DMR Procedure using the Revita® System compared to a sham. Subjects randomized to the DMR procedure will be followed per protocol till 48 weeks post treatment. Subjects in the Sham treatment arm will be offered cross over to receive the DMR treatment at 48 weeks and will be followed per protocol for 24 weeks post treatment.
