NOYA I: A Prospective Randomized Trial of NOYATM Sirolimus-Eluting Stent with Biodegradable Coating Compared to FIREBIRD 2® Sirolimus-Eluting Stent with Durable Coating in Patients with Coronary Artery Disease 9-Month Angiographic and 12-Month Clinical Results (NCT: ) Run-Lin Gao, MD Cardiovascular Institute and Fu Wai Hospital National Center for Cardiovascular Disease of China For the NOYA I Investigators 4:10 PM-4:20 PM, Tuesday, May 17th, Main Arena, Late Breaking Trials

NOYA I Background The biocompatibility of durable polymer used in the 1st generation of DES was considered to be one of the potential reasons for delaying endothelial healing, which may induce very late stent thrombosis Biodegradable polymer coating may potentially improve endothelial healing NOYATM, a Co-Cr stent platform, DL-Polylactide biodegradable polymer coated with sirolimus was developed and manufactured by Medfavour Medical (Beijing, China)

The Control Group FIREBIRD 2®, a Co-Cr stent platform, biocompatible durable polymer coated with sirolimus, is manufactured by MicroPort Medical (Shanghai, China) FIREBIRD 2® is one of the most popularly used DESs in clinical practice in China; more than 300,000 stents have been implanted worldwide; clinical studies and post marketing surveillance confirmed its efficacy and safety The only difference between NOYATM and FIREBIRD 2® is the polymer, biodegradable or durable; the longterm follow-up would be valuable to determine the significance of biodegradable polymer coating

Conclusions The present data indicates that the NOYATM SES is non-inferior to FIREBIRD 2 SES with respect to in-stent late loss at 9-month The in-stent late loss of NOYATM SES at 9-month is 0.11±0.20 mm, and the in-segment binary restenosis rate is 4.2% The rates of MACE (4.7%) and TLF (4.7%) in NOYA group are the same as that in FIREBIRD 2 group, no stent thrombosis observed in both groups The efficacy and safety of NOYATM SES are documented by the present randomized trial Large scale trials and long term follow-up are needed to further evaluate the newly developed SES with biodegradable polymer coating
