Data from two patient registries in commercialized markets, clinical research and a meta-analysis of 13 clinical studies highlighted in four presentations at EASD

LEXINGTON, Mass. & BARCELONA, Spain – 25 September 2013 – GI Dynamics, Inc. (ASX: GID) announced today that EndoBarrier® Therapy data from two patient registries in commercialized markets (U.K. and the Netherlands), clinical research from Germany and a meta-analysis of 13 clinical studies were the focus of four presentations at the 49th Annual Meeting of the European Association for the Study of Diabetes (EASD) held 23 – 27 September 2013 in Barcelona, Spain.

“Type 2 diabetes requires new treatment options that help patients achieve metabolic control as existing options are not adequately addressing the needs of patients and physicians,” stated David Maggs, M.D., chief medical officer, GI Dynamics. “There is a growing recognition among physicians worldwide of the strong impact that EndoBarrier Therapy can have and where it fits within the existing treatment options for type 2 diabetes and obesity. These data presented at EASD and data from previous clinical studies, continue to demonstrate and validate the use of EndoBarrier Therapy as part of an effective type 2 diabetes treatment program.”

EndoBarrier Therapy Oral Presentation

During the oral presentation, “Interim 12-month results from a post-market clinical trial of DJBL treatment outcomes in subjects with type 2 diabetes and/or obesity,” Dr. Julian Teare, Imperial College of London, discussed health improvements achieved through EndoBarrier Therapy in 32 patients. From baseline, patients experienced a one percent decrease in HbA1c, enabling them to achieve better overall glycemic control. In addition, patients achieved a mean weight loss of 26.4 lb (11 kg), along with reductions in blood pressure, cholesterol and triglycerides.[i]

EndoBarrier Therapy Poster Presentations

Additional poster presentations on EndoBarrier Therapy were featured during the meeting that continue to demonstrate positive treatment outcomes and utility in type 2 diabetes.

“We are very pleased with the progress that we have made in our key European markets and the growing adoption of EndoBarrier Therapy by endocrinologists, as evidenced by the initiation of clinical studies by leading health authorities in France and the United Kingdom,” said Stuart A. Randle, president and chief executive officer, GI Dynamics. “The data presented at EASD and the findings from these ongoing studies are designed to help further establish EndoBarrier Therapy as a standard treatment option for type 2 diabetes with local health authorities and in influential treatment guidelines.”

EndoBarrier Therapy is currently the subject of clinical studies being conducted in France and the U.K. The French Ministry of Social Affairs and Health approved funding for the ENDOMETAB trial, a large, randomized, multicenter clinical utility study of EndoBarrier Therapy. The study will be coordinated by the University Hospital of Lille. ENDOMETAB is part of the soutien aux techniques innovantes couteuses (STIC) program, which provides government funding for innovating medical technologies that have been validated by prior clinical studies with a view toward establishing reimbursement for new devices. In the U.K., the Association of British Clinical Diabetologists has initiated the REVISE-Diabesity study, which is being funded by a grant from the Diabetes Care Trust (ABCD), Registered Charity Number 1139057 in the U.K., and is supported by the U.K.’s publicly-funded health system, the National Health Service (NHS), as one of the National Institute for Health Research Clinical (Diabetes) Research Network Portfolio Studies.

EndoBarrier is a thin, flexible, tube-shaped liner that forms a physical barrier between ingested food and a portion of the wall of the intestine. Inserted endoscopically (through the mouth without any cutting or scarring of tissue), the EndoBarrier liner prevents the interaction of food with enzymes and hormones in the proximal intestine. In effect, food bypasses the duodenum, but without surgery or permanent changes to the anatomy. In clinical studies, more than 80% of patients were able to reach healthy blood glucose levels (HbA1c ≤ 7.0%) and achieve weight loss of approximately 15-20 percent within one year.[ii],[iii] EndoBarrier Therapy is currently available in seven European countries, as well as in Australia, Chile and Israel.
