About
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 on one or more glucose lowering agents. 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 48 weeks post treatment.

Exclusion Criteria
Subjects who meet any of the following exclusion criteria are not allowed to be included in the study:

Clinically significant hypoglycemia occurring during the run-in period, defined as a) 2 or more glucose alert values of ≤70 mg/dL (3.9 mmol/L) unless a clear, correctable, precipitating factor can be identified; b) clinically significant hypoglycemia with self-monitored or laboratory plasma glucose level <54 mg/dL (3.0 mmol/L); or c) severe hypoglycemic episode requiring third party assistance

Known active coagulopathy or current upper gastro-intestinal bleeding conditions such as ulcers, gastric varices, strictures, or congenital or acquired intestinal telangiectasia
