The purpose of this study is to demonstrate the efficacy and safety of the Fractyl duodenal mucosal resurfacing (DMR) Procedure using the Revita System compared to a sham procedure for the treatment of uncontrolled type 2 diabetes.

Subjects randomized to the DMR procedure are followed per protocol for 48 Weeks. The Sham treatment arm will cross over to receive the DMR treatment at 24 weeks with background medications held constant from 24-48 weeks of follow up.

The study is a multi-center, randomized, prospective, double-blinded (subject and endocrinologist) trial of type 2 diabetes patients sub-optimally controlled on 1 or more oral anti-diabetic medications comparing the Fractyl DMR procedure to sham procedure. Randomization will be 1:1 DMR treatment to sham. All subjects will participate in a 4 week oral anti-diabetic medication run-in period before the index procedure to confirm lack of blood glucose control in conjunction with medication compliance and nutritional counseling. The Sham treatment arm will cross-over to receive the DMR treatment at 24 weeks with background medications held constant 24weeks of follow up after the cross-over DMR procedure. The DMR treatment arm will be managed according to current diabetes standard of care.

Subjects randomized to the DMR procedure are followed per protocol for 48 Weeks. The Sham treatment arm will cross over to receive the DMR treatment at 24 weeks with background medications held constant from 24-48 weeks of follow up.
