GI Dynamics, Inc. - ASX Announcement

Compliance with Therapeutics Goods Act (Australia) LEXINGTON, Massachusetts & SYDNEY, Australia - 20 May 2016 AEST - GI Dynamics, Inc. (ASX: GID) (the Company), a medical device company that provides an innovative treatment for type 2 diabetes and obesity, announces that there is a material risk of action by the Australian Therapeutic Goods Administration (TGA) for compliance-related matters.

The Company's EndoBarrier device is included on the Australian Register of Therapeutic Goods (ARTG), which enables EndoBarrier to be sold commercially in Australia subject to the requirements of the Therapeutic Goods Act 1989 (Cth) (the Act). EndoBarrier has been included on the ARTG since 2011.

The Company has been in communication with the TGA regarding compliance-related matters since January 2015. While the conclusion of these communications is not foregone, a material risk exists that the TGA may take action in regard to EndoBarrier in the near future.

The TGA has raised a number of specific questions and has required that the Company provide sufficient evidence to demonstrate compliance with the Essential Principles under the Act. The Essential Principles set out certain requirements that must be met with respect to a medical device in order for it to be supplied in Australia.

The TGA has afforded the Company until 9 June 2016 for it to submit its response addressing the TGA's concerns. If the TGA is not satisfied with the Company's response, the TGA has indicated it will suspend EndoBarrier from inclusion on the ARTG. Suspension does not constitute a cancellation of the ARTG inclusion.

The Company is preparing its response under the leadership of recently appointed chief compliance officer Brian Callahan, a seasoned industry executive with substantial expertise in regulatory compliance.

Scott Schorer, president and CEO of the Company said, "We are focused on addressing the TGA's concerns as quickly and effectively as possible. Our response to the TGA is of the highest priority to GI Dynamics. I stated when I joined the Company that I was committed to promoting a culture of greater transparency with a sharper focus on positive regulatory relationships. The disclosure of this risk and our response to it are key components of that commitment."

Further updates will be provided in due course.
