JenaValve Technology, Inc., a developer, manufacturer and marketer of differentiated transcatheter aortic valve replacement (TAVR) systems for the treatment of aortic valve disease, today announced successful patient enrollment in the CE Mark study of the next generation JenaValve Pericardial TAVR System utilizing the CoronatixTM Transfemoral Delivery Catheter for the percutaneous treatment of severe aortic stenosis. The JenaValve Pericardial TAVR System is an investigational device in the United States and internationally.

The JenaValve system is proprietary and differentiated from prior technologies,
comprising the Everdur™ Pericardial Aortic Valve with locator-based technology
designed for more predictable implantation, combined with the new 18-Fr compatible
CoronatixTM Transfemoral Delivery Catheter. The optimized TAVR system has now
been used to treat 10 patients across three sites in Germany and New Zealand. Technical success for those procedures was 100%, with no reported adverse events and no moderate or higher paravalvular leakage reported.

The CE Mark study is an international, prospective, non-randomized, single-arm trial of the JenaValve Pericardial TAVR System for the treatment of severe aortic stenosis in
patients who are at increased risk for conventional surgical valve replacement.

The German national Principal Investigator, Prof. Dr. med. Hendrik Treede (Halle
University, Halle, Germany), said, “The novel JenaValve transcatheter valve may address
the ongoing clinical needs for these patients. Specifically, early experience with this
innovative transcatheter heart valve demonstrates low permanent pacemaker rates,
negligible mean pressure gradients across the valve and no significant paravalvular
leaks. Additionally, the new transfemoral system enables rapid, safe, and reliable
delivery of this new valve.”

“We were already extremely pleased with the initial clinical results of our next generation TAVR valve, Everdur. Now, the most recent implants using the optimized delivery system have shown significantly improved ease of use and performance,” said JenaValve Chief Executive Officer Victoria Carr-Brendel, PhD. “We have invested a substantial amount of intellectual know-how, capital and time to develop the Everdur valve and Coronatix delivery catheter, and they are exceeding our expectations. We look forward to expanding our clinical development programs and building on this initial body of clinical evidence to eventually improve results, quality of life and survival among patients suffering these very serious conditions.”

The Company expects to complete patient enrollment by mid-2018 at clinical sites in
Germany, The Netherlands, New Zealand and the United States. The Company
anticipates CE Mark approval by the end of 2018.
