Study Sites Announced for EndoBarrier Trial

Massachusetts-based GI Dynamics, Inc. says it is currently enrolling subjects at 17 sites across the United States for its clinical trial of the EndoBarrier for people who have uncontrolled type 2 diabetes and are obese. The company expects to enroll approximately 500 people who meet the enrollment criteria at up to 25 sites in the United States.

EndoBarrier is a thin, flexible, tube-shaped liner that forms a physical barrier between food and a portion of the wall of the intestine. GI Dynamics has conducted 12 clinical studies of its product outside the United States and one within. It currently is pursuing U.S. regulatory approval, and the 500-prson EndoBarrier trial is one of the benchmarks it must meet.

The trial is designed to assess improvements in diabetes over a treatment period of up to 12 months. The primary endpoint of the trial is improvement in HbA1c (a key blood sugar measure for diabetes); secondary measures include weight loss and improvement in select cardiovascular risk factors, such as cholesterol.

Eligible patients who would like to enroll in the trial should be between the ages of 21 and 65, have a body mass index between 30 and 50, have uncontrolled type 2 diabetes and currently use metformin, a sulfonylurea, or a combination of both, but are unable to achieve adequate glycemic control.
