Trial to Evaluate Efficacy+Safety of Revita DMR Treatment Paradigm 1 and Retreatment in Type 2 Diabetes Patients (REMIND)

A Randomized Double-blind Sham-controlled Trial to Evaluate Efficacy+Safety of Revita Duodenal Mucosal Resurfacing (DMR) Treatment Paradigm+Retreatment in Patients With Type 2 Diabetes Using Non-insulin Glucose Lowering Medications (REMIND)

The objective of this study is to evaluate feasibility, safety, and efficacy of endoscopic DMR Treatment Paradigm 1 (compared to sham) and to evaluate feasibility, safety, and efficacy of re-treatment with DMR at 24 weeks (compared to baseline and a single DMR procedure) in patients with type 2 diabetes with non-insulin glucose lowering medications.

Study Overview

• Status: Recruiting
• Conditions: Diabetes Mellitus, Type 2
• Intervention / Treatment: Device: Revita® DMR Treatment; Other: Sham procedure

Detailed Description

The objective of this study is to evaluate feasibility, safety, and efficacy of endoscopic DMR Treatment Paradigm 1 (compared to sham) and to evaluate feasibility, safety, and efficacy of re-treatment with DMR at 24 weeks (compared to baseline and a single DMR procedure) in patients with type 2 diabetes with non-insulin glucose lowering medications.

The aimed effect is an adequate or improved glucose regulation and a decrease of HbA1c. Secondary effects include improved cardiovascular, hepatic, and metabolic parameters.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: DMR procedure; Patients receive Revita® DMR Treatment Paradigm 1. After unblinding at 24 weeks, they receive retreatment.	Device: Revita® DMR Treatment; The Revita® System is an endoscopic treatment consisting of a single catheter and console designed to lift the duodenal mucosa with saline followed by controlled circumferential hydrothermal ablation of the mucosa. For this study Revita® DMR procedure will be conducted as follows: DMR Treatment Paradigm 1- After initial 2 Lift and Ablate step, remaining Lift: Ablate steps will be conducted in 1:1 manner.; Other Names: Revita® DMR Treatment Paradigm 1; Revita Duodenal Mucosal Resurfacing
Sham Comparator: Sham procedure; Patients receive a sham procedure. After unblinding takes place at 24 weeks, patients receive a Revita® DMR Treatment Paradigm 1. 48 weeks after initial sham (= 24 weeks after first DMR) patients may receive retreatment, if they want to.	Other: Sham procedure; The sham control for the Revita DMR procedure.
