EVOLVE Study Data Presented Today at EuroPCR 2014 Also Demonstrate Excellent Safety Profile

Boston Scientific Corporation reported positive three-year follow-up data for the EVOLVE clinical trial, comparing the safety and performance of the SYNERGY Everolimus-Eluting Bioabsorbable Polymer Platinum Chromium (PtCr) Coronary Stent System to the PROMUS Element Stent System.

The data were presented today at EuroPCR 2014 by Professor Ian Meredith, director of MonashHeart, at Monash Medical Centre in Melbourne, Australia. The primary clinical and angiographic endpoints of this non-inferiority study have already been published.

"The SYNERGY Stent three-year results from the EVOLVE trial continue to show promise with respect to safety and efficacy," said Meredith. "Target lesion revascularization remains very low, at a rate of 1.1 percent, while there is no stent thrombosis in the SYNERGY full-dose arm at three years. The EVOLVE clinical data support the hypothesis that this novel bioabsorbable polymer stent technology could allow for improved healing over durable polymer DES."

Boston Scientific has expanded its commercial launch of the SYNERGY Stent System in Europe and in select markets in Asia. It features an ultrathin abluminal bioabsorbable drug/polymer coating technology which eliminates long-term polymer exposure. In addition to reducing restenosis, the SYNERGY Stent System may also offer faster and more complete vessel healing after stent implantation, potentially reducing the duration of post-procedure dual antiplatelet therapy.

"The SYNERGY Stent System underscores our ongoing commitment to delivering meaningful innovation to the interventional cardiology community and is expected to reinforce our position as a global leader in medical devices," said Kevin Ballinger, president, Interventional Cardiology, Boston Scientific. "The SYNERGY Stent System is uniquely designed to provide exceptional outcomes in complex cases by promoting early healing and eliminating long-term polymer exposure.

The SYNERGY Stent System is supported by a rigorous clinical program. Beyond the EVOLVE Study three-year results, the EVOLVE II Clinical Trial, which completed enrollment in August 2013, is the pivotal trial designed to support U.S. Food and Drug Administration and Japanese Ministry of Health, Labor and Welfare approval of the SYNERGY Stent System. EVOLVE II is a global, multicenter, randomized, controlled pivotal trial that enrolled 1,684 patients in 125 sites worldwide, including the U.S., Canada, Europe, Australia, New Zealand, Japan and Singapore. Additional studies to assess outcomes, including the potential for reduced dual antiplatelet therapy, will be supported by Boston Scientific. The SYNERGY Stent System is being investigated in multiple independent, real-world studies across the spectrum of cardiovascular disease complexity.

The SYNERGY Stent System is an investigational device in the U.S. and Japan, and is not available for sale in those countries.
