Brief Summary

The purpose of the study was to evaluate the safety and efficacy of the EndoBarrier Gastrointestinal Liner compared to sham control in subjects with Type 2 diabetes.

Detailed Description

The study was designed as a randomized, single blind, sham controlled, pilot efficacy study of subjects with Type 2 diabetes enrolled at 2 centers in Santiago, Chile. Subjects were enrolled at a 2:1 ratio (EndoBarrier to sham). Following implantation or sham procedure, subjects were treated for 24 weeks or 52 weeks. Following explant, subjects were followed for an additional 8-12 weeks.

Subject evaluations included measurements of HbA1c, glucose, insulin, weight, changes in diabetic medications, and meal tolerance tests. Safety was monitored through the collection of clinical labs, physical assessments, endoscopy and adverse events.

Conditions

Type 2 Diabetes

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: SINGLE

Study Groups

EndoBarrier Gastrointestinal Liner

Subjects randomized and implanted with the EndoBarrier Gastrointestinal liner; subjects will be implanted for 24 weeks to 52 weeks and evaluated for study endpoints.

Group Type: EXPERIMENTAL

EndoBarrier Gastrointestinal Liner

Intervention Type: DEVICE

The EndoBarrier is a single use, implant consisting of a tube of composite material which is placed in the proximal section of the duodenum. The implant is fixed in place with the aid of a metal anchor. The device is delivered via an endoscope. The implant facilitates the passage of food from the stomach through the tube to the proximal section of the jejunum.

Sham: endoscopy and standard of care

Subjects randomized to sham arm received an upper GI examination and were evaluated for study endpoints.

Group Type: EXPERIMENTAL

Sham: endoscopy and standard of care

Intervention Type: OTHER

Sham subjects had an endoscopic procedure and then received standard of care treatment of their diabetes
