Billings Clinic Becomes First U.S. Site to Initiate Clinical Trial of EndoBarrier® for the Treatment of Type 2 Diabetes in People Who are Obese

ENDO Trial Information Available by Calling 1-888-9STUDY9 (1-888-978-8399)

Billings, MT— Billings Clinic today announced it is the first hospital in the United States to initiate the ENDO Trial, a pivotal clinical trial of EndoBarrier® for the treatment of patients who have uncontrolled type 2 diabetes and are obese. The ENDO Trial, EndoBarrier: a novel therapy for type 2 diabetes in obese adults, will evaluate the efficacy and safety of EndoBarrier, a thin, flexible, tube-shaped liner that forms a physical barrier between food and a portion of the wall of the intestine.

“We are very pleased to be participating in the ENDO Trial and look forward to the potential positive health outcomes that EndoBarrier may provide patients,” offered site investigator, Christopher Sorli, MD, Billings Clinic Endocrinologist. “We regularly see patients who have difficulty managing their type 2 diabetes and obesity and may benefit from this novel therapy.”

The prevalence of diabetes continues to rise sharply across the country. According to a recent report from the U.S. Centers for Disease Control and Prevention, the prevalence of diabetes has grown to more than 6 percent of the population in all states as well as Washington, D.C. and Puerto Rico. In Montana, the prevalence of diabetes is now 6.2 percent, an increase of 117 percent since 1990. Type 2 diabetes, which accounts for approximately 90 percent of all cases of diabetes, affects more than 23 million people in the U.S. and approximately 55,000 people in Montana. The diagnosis of type 2 diabetes usually occurs after the age of 40 and is often, but not always, associated with obesity.

“There are many people living with type 2 diabetes and obesity who are trying tirelessly to manage their conditions without success. While diabetes is often treated with diet and lifestyle changes and medications, many patients still struggle to get their blood sugar under control,” offered Dr. Sorli.

The ENDO Trial is currently enrolling adults between the ages of 21 and 65 who have uncontrolled type 2 diabetes and are obese. Eligible patients should currently be using metformin, a sulfonylurea, or a combination of both, but unable to achieve adequate glycemic control. More information about the ENDO Trial can be found at or by calling 1-888-9STUDY9 (1-888-978-8399).

About EndoBarrier
EndoBarrier is a thin, flexible, tube-shaped liner that forms a physical barrier between food and a portion of the wall of the intestine. In 12 clinical studies conducted outside the United States and one conducted in the United States, with more than 500 patients, EndoBarrier has been tested in similar patient populations. EndoBarrier received CE Mark approval in 2010, and approval by the Therapeutic Goods Administration in Australia in 2011 for the treatment of type 2 diabetes and/or obesity for up to 12 months. EndoBarrier is now pursuing commercial status in the United States. The first step in this process is a successful completion of the ENDO Trial. The device was developed by GI Dynamics, Inc., based in Lexington, Mass. More information about the company may be found at

About the ENDO Trial
The ENDO Trial is a randomized, double-blind, sham controlled, multi-center trial that is expected to enroll approximately 500 people living with uncontrolled diabetes and obesity who meet specific enrollment criteria at up to 25 sites in the United States. 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.
