GI Dynamics Release: German Registry Releases Positive EndoBarrier Data At EASD

• Mean reduction in absolute HbA1c of 1.3%
• Insulin usage dropped 42%
• GLP-1 usage reduced in 78% of patients
• Excess weight loss of 15kg, or 29% of excess weight
• 234 patients included (March 2016)

BOSTON & SYDNEY--(BUSINESS WIRE)--GI Dynamics, Inc. (ASX: GID) (GI Dynamics or the Company), a medical technology company that has developed an innovative device to improve outcomes for patients diagnosed with type 2 diabetes and obesity, continues to demonstrate clinical benefit in Germany.

“Patients significantly benefitted from improvement of HbA1c, reduction of antidiabetic medication, reduction of weight and were able to improve obesity-associated comorbidities.”

The German EndoBarrier registry, which is run at the University Hospital Hamburg-Eppendorf (UKE), recently released positive data at the EASD (European Association for the Study of Diabetes). Dr Nina Riedel of UKE presented data from 234 patients at the EASD in Munich, Germany.

The EndoBarrier produced clinically relevant results, lowering absolute HbA1c mean from 8.5% to 7.2%. This occurred in concert with a lowering of antidiabetic medication in 78% of patients, and reducing the injected dose of Insulin by 42% on a mean basis.

Dr. Riedel said, “Patients significantly benefitted from improvement of HbA1c, reduction of antidiabetic medication, reduction of weight and were able to improve obesity-associated comorbidities.”

Excess weight also dropped by a mean of 15kg, which represented a 29% drop in excess weight. In addition, a mean drop of 10cm waist circumference (9% drop) was achieved.

EndoBarrier safety profile was clinically acceptable with a 1.7% event rate of hepatic abscess (4/234) and a severe bleeding rate of 0.4%. All safety-related events were resolved with no long-term complications.

This interim analysis included 234 patients. The German Registry continues to expand, and has input more than 300 patients to date.

“The data emerging from the German EndoBarrier Registry continues to support the strong efficacy and safety profile of EndoBarrier” said Scott Schorer, President & CEO of GI Dynamics. “We are encouraged by this early review, and look forward to continued clinical conclusions to be drawn from this rapidly expanding registry effort.”

“We would like to thank all participating hospitals for their contribution,” said Schorer.

The registry is supported by a grant from GI Dynamics with no access by the company to non-published or primary results. GI Dynamics has no influence on analysis of the registry results.
