BOSTON and SYDNEY — 15 March 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 positive results on final data from the United Kingdom’s National Health Service (NHS) EndoBarrier Service. Principal investigator Robert Ryder, M.D., of Sandwell and West Birmingham Hospitals presented the results at the Diabetes UK Professional Conference 2019 in Liverpool last week. The data show a significant reduction in HbA1c, weight, liver fat and cardiovascular disease (CVD) risks as well as a reduction in the need for insulin in some patients.

This study, titled “UK First NHS EndoBarrier Service for Advanced Type 2 Diabetes and Obesity: One-Year Outcomes in All Patients Treated,” is based on data collected from the first implant in October 2014 to the last explant in November 2018, a total patient population of 61.

The primary outcome of HbA1c, weight, CVD risk factors and alanine aminotransferase (ALT — a liver fat measure) show a significant reduction at explant compared to baseline values. Of the 61 patients studied, 35 were on insulin prior to treatment. At explant, 10 of the 35 (28.6 percent) discontinued their use of insulin.

The most significant outcome measure is the 2.2 absolute percent reduction of HbA1c at 12 months with a concurrent weight loss of 15.9 kg (35 lbs.), highlighting the dual primary treatment effect of EndoBarrier.

Ryder input all data from this study into the UK Prospective Diabetes Study (UKPDS) Risk Engine provided by the Diabetes Trials Unit of The Oxford Centre for Diabetes, Endocrinology and Metabolism. Through that evaluation, Ryder analyzed the potential impact of EndoBarrier on 10-year CVD risk for patients with type 2 diabetes and obesity.

Utilizing the UKPDS Risk Engine and clinical results from EndoBarrier in this study, approximately 8 of 100 patients would avoid coronary heart disease or a stroke event over the next 10 years.

“We are pleased to share the final outcome from this study, which suggests EndoBarrier can provide significant improvements for patients with long-standing poorly controlled diabetes and obesity, who have been unable to manage their diabetes with standard treatment options,” said Ryder. “Further evidence and research suggest EndoBarrier contributes to the reduction of other comorbidities associated with type 2 diabetes and obesity.”

“This expanded data set from the NHS EndoBarrier Service continues to develop the breadth of support for clinical efficacy of EndoBarrier in a real-world clinical setting,” said Scott Schorer, president and chief executive officer. “The significant reduction of HbA1c, weight and improvement in numerous markers — including reduction in cardiovascular risk and elimination of insulin use for 28 percent of patients — is substantial.”
