Safety and Effectiveness of Endoscopic Intestinal Re-Cellularization Therapy in Individuals With Type II Diabetes (ReCET)

A Multicenter, Randomized, Double-blind, Sham-controlled Study for Assessing the Safety and Effectiveness of Endoscopic Intestinal Re-Cellularization Therapy in Individuals With Type II Diabetes (ReCET Study)

This study is designed to evaluate the safety and effectiveness of endoscopic intestinal re-cellularization therapy in individuals with type 2 diabetes (T2D) inadequately controlled on non-insulin glucose-lowering medications.

Study Overview

• Status: Recruiting
• Conditions: Diabetes Mellitus, Type 2; Diabetes; Type 2 Diabetes Mellitus; Type 2 Diabetes; Type2diabetes
• Intervention / Treatment: Device: ReCET Treatment; Device: Sham Procedure

Detailed Description

This is a prospective, multi-center, randomized, double-blind, sham-controlled, adaptive study enrolling individuals with type 2 diabetes inadequately controlled on non-insulin glucose-lowering medications. Participants will be randomized to receive the ReCET therapy or sham procedure consisting of device insertion without treatment. Participants will be followed for 6 months for the primary endpoint and 12 months in total. After 12 months, participants randomized to the sham arm may cross-over to receive the ReCET procedure.

Study Plan

How is the study designed?

Design Details

• Primary Purpose: Treatment
• Allocation: Randomized
• Interventional Model: Sequential Assignment
• Masking: Quadruple

Number of Arms

2

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: ReCET Arm; Treatment Arm will receive the ReCET procedure.	Device: ReCET Treatment; Treatment arm will receive the ReCET therapy. The ReCET procedure utilizes the ReCET catheter to deliver non-thermal pulsed electric field to the first portion of the small intestine (duodenum) to induce cell regeneration. The catheter is introduced to the duodenum through the mouth using a guide wire and the therapy is applied to treat the duodenum. Participants will be followed for 12 months post procedure.; Other Names: duodenal mucosal resurfacing
Sham Comparator: Control Arm; Control Arm will receive a sham procedure.	Device: Sham Procedure; The Control arm will receive a sham procedure. The sham procedure consists of placing the ReCET catheter as described above without therapy applied. Participants will be followed for 12 months post procedure and will be offered cross-over to receive the ReCET therapy after 12 months.
