简要总结
The Revita™ System is being investigated to assess the ability to improve glycemic control in conjunction with diet and exercise in patients with Type 2 diabetes who are inadequately controlled with oral anti-diabetic medications. The purpose of this study is to demonstrate the safety and effectiveness of the Fractyl DMR Procedure using the Revita™ System compared to a sham procedure. At 24 weeks, subjects randomized to the DMR procedure be continued to be followed per protocol till 48 Weeks and the Sham treatment arm will be offered to cross over to receive the DMR treatment and will be followed per protocol for 24 weeks post treatment.
详细描述
The study is a randomized, double-blind sham-controlled prospective multi-center clinical investigation of subjects with T2D sub-optimally controlled on two oral anti-diabetic medications, one of which must be metformin, comparing the Fractyl DMR procedure using the Revita™ System to a sham procedure. All subjects will participate in a 4 week oral anti-diabetic medication run-in period before the procedure to confirm inadequate blood glucose control in conjunction with medication compliance and nutritional counseling. Subjects who meet all criteria after screening are randomized 2:1 (DMR to sham), with double blinding (subject and endocrinologist/Sponsor). The endoscopist is not blinded.

Note: For subjects on sulfonylurea (SU) glucose-lowering drugs for diabetes, the only SUs permitted in the study will be glipizide or glimepiride, and their doses below half maximum labeled dosing will not be an exclusion for study entry. Patients unwilling to reduce the dose of SU at the time of the DMR procedure as described by protocol will be excluded.
