BOSTON and SYDNEY — 23 July 2019 — GI Dynamics® Inc. (ASX:GID), a medical device company that is developing EndoBarrier® for patients with type 2 diabetes and obesity, is pleased to announce execution of its contract with Thomas Jefferson University in Philadelphia, Pennsylvania as the fourth clinical site of the U.S. pivotal trial of EndoBarrier.

The U.S. pivotal trial of EndoBarrier, STEP-1 (Single Therapy Euglycemic Procedure), formally known as GID 18-1, will begin enrolling patients with type 2 diabetes and obesity during the second half of 2019. The primary endpoint of STEP-1 is reduction in average blood sugar levels (HbA1c) at 12 months of treatment. The pivotal trial will consist of randomized EndoBarrier implant and control arms; both arms will receive identical lifestyle therapy that complies with the most current American Diabetes Association guidelines.

Thomas Jefferson University Hospital (Thomas Jefferson) is a medical institution frequently recognized for its dedication to patient care and the quality of its healthcare professionals, coupled with its drive for innovation and clinical research. Ranked in the top 10 facilities in Pennsylvania by the U.S. News & World Report and the top 100 facilities in America by Becker’s Hospital Review, Thomas Jefferson was commended for the quality of its clinicians by Philadelphia Magazine’s 2019 Top Doctors.

Thomas Jefferson’s Principal Investigator, Austin Lee Chiang, M.D., M.P.H., is an assistant professor and director of the endoscopic bariatric program at Thomas Jefferson. Dr. Chiang’s expertise as a board-certified specialist in gastroenterology, internal medicine, and obesity medicine will provide valuable leadership to the study.

“I am excited for Thomas Jefferson University Hospital to participate in this very important trial in helping identify solutions for patients with type 2 diabetes and other metabolic diseases,” said Dr. Chiang.

“We are pleased to have secured Thomas Jefferson as our fourth clinical site for the STEP-1 trial,” said Steve Linhares, vice president of clinical and regulatory affairs of GI Dynamics. “The team at Thomas Jefferson, lead by Dr. Chiang, will prove to be a solid clinical site with patient safety as their top priority.”
