BOSTON and SYDNEY — 4 July 2018 — 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 further positive results from the ongoing National Health Service (NHS) EndoBarrier Service in the U.K., which Robert Ryder, MD, of Sandwell and West Birmingham Hospitals presented at the American Diabetes Association’s (ADA) 78th Scientific Sessions.

The study, “U.K.’s 1st National Health Service (NHS) EndoBarrier Service: Outcomes in 1st 38 Patients to Reach 6 Months After Device Explant,” is based on the outcome from 38 of the 62 patients who completed six months post EndoBarrier removal since the NHS Service began in October 2014. Of these patients, 31 attended the 6-month follow-up appointment, making it possible to assess the outcome post treatment.

The primary outcomes of HbA1c, weight and BMI showed a significant reduction at explant and six months post explant compared to baseline values. Patients also saw a significant reduction in systolic blood pressure. A major triumph is that patients who were on insulin (n=20) saw a significant reduction in their daily dosage which remained significant after explant. Thirty-five percent of these patients discontinued the use of insulin even after EndoBarrier was explanted.

Of the 31 patients, 21 (68 percent) maintained the treatment effect post explant. For the patient cohort that did not retain benefit, some mean reduction in HbA1c was still maintained. Many of the patients who saw their benefit deteriorate reported other personal matters in their lives and 70 percent were diagnosed with depression.

This study is an extension of the poster “Maintenance of Efficacy After EndoBarrier in UK 1st National Health Service (NHS) EndoBarrier Service,” presented in June 2017 at ADA’s 77th Scientific Sessions, consisting of data  for 12 patients who reached the six month post explant point.

“We are pleased to present additional data suggesting that EndoBarrier can provide substantial clinical benefit post removal,” said Robert Ryder, MD. “The mean reduction in HbA1c of 2.5 percent and mean reduction in weight of 16kg are clinically significant, especially as many of these patients’ gains were accompanied by significant reduction in diabetic medications, in particular insulin”

“This release of clinical data further reinforces treatment durability of EndoBarrier after removal, with 68 percent of patients retaining significant clinical benefit six months after removal,” said Scott Schorer, president and chief executive officer of GI Dynamics. “We are pleased that expanded clinical data indicates EndoBarrier has a treatment effect that extends beyond the treatment period in many patients. GI Dynamics is focused on providing patients with the ability to improve their health and maintain a healthy lifestyle.”
