Notified Body, following review, clears Company to resume shipments

LEXINGTON, Massachusetts – 1 December 2014 – GI Dynamics, Inc. (ASX: GID), a medical device company developing innovative treatments for type 2 diabetes and obesity, today announced that its Notified Body in the European Union, an organization that has been accredited by Member States to assess whether a product meets the requirements of the EU Medical Device Directive 93/42/EEC, has cleared the Company to resume commercial product shipments. Today’s decision by the Notified Body will permit the Company to resume commercial activities in all jurisdictions where it was previously selling EndoBarrier®.

As a result of a review of the Company’s historical Clinical Evidence for the EndoBarrier product, the Company will clarify its indications for use to reflect that its obesity indication includes a restriction to patients with a body mass index (BMI) ≥ 30 kg/m2. The Company’s revised indications for use will now read: The GI Dynamics’ EndoBarrier® Gastrointestinal Liner System is used for the treatment of obese type 2 diabetes with BMI ≥ 30 kg/m2, or obese patients with BMI ≥ 30 kg/m2 with ≥ 1 co-morbidities, or obese patients with BMI >35 kg/m2. Based on these indications for use, and the Clinical Evidence used for the review, the Risk:Benefit profile of EndoBarrier Therapy is considered appropriate.

Michael Dale, the Company’s president and chief executive officer, said, “We are pleased to have resolved the outstanding questions surrounding EndoBarrier Therapy and want to thank all stakeholders for their patience during this recent period of review and remediation of matters related to our vigilance systems. I truly believe that, as a result of this experience, we are a stronger organization. On behalf of all GI Dynamics employees; I want to assure our patients, physicians and regulatory authorities around the world of our absolute commitment to continuous quality improvement in all that we do.”
