  12. Use of anticoagulation therapy (such as warfarin) which cannot be discontinued for 7 days before and 14 days after the procedure
  13. Use of P2Y12 inhibitors (clopidogrel, pasugrel, ticagrelor) which cannot be discontinued for 14 days before and 14 days after the procedure. Use of aspirin is allowed.
  14. Unable to discontinue NSAIDs (non-steroidal anti-inflammatory drugs) during treatment through 4 weeks post procedure phase
  15. Taking corticosteroids or drugs known to affect GI motility (e.g. Metoclopramide)
  16. Receiving weight loss medications such as Meridia, Xenical, or over the counter weight loss medications

  20. Active malignancy within the last 5 years
  21. Not potential candidates for surgery or general anesthesia
  22. Active illicit substance abuse or alcoholism
  23. Participating in another ongoing clinical trial of an investigational drug or device
  24. Any other mental or physical condition which, in the opinion of the Investigator, makes the subject a poor candidate for clinical trial participation

5. Study Description

Brief Summary
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.
Detailed Description
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.
