NATICK, Mass. and BARCELONA, Spain, May 13 /PRNewswire-FirstCall/ -- Boston Scientific Corporation (NYSE: BSX) today welcomed two-year results from the SPIRIT III clinical trial, which continue to reaffirm the proven long-term safety and efficacy of the market-leading TAXUS(R) Express2(TM) Paclitaxel-Eluting Coronary Stent System and reinforce the growing body of positive clinical evidence for the XIENCE(TM) V (PROMUS(TM)) Everolimus-Eluting Coronary Stent System. The results were presented at the 2008 EuroPCR Scientific Program in Barcelona by Gregg W. Stone, M.D., of Columbia University Medical Center and the Cardiovascular Research Foundation in New York, and the Principal Investigator of the SPIRIT III Trial.
The results demonstrated comparable safety and efficacy rates through two years for the XIENCE V (PROMUS) and TAXUS Express Stents. The Ischemia-Driven Target Lesion Revascularization (TLR) rate for the XIENCE V (PROMUS) Stent was 4.3% while the TAXUS Express Stent was 6.9% (p=0.07). The overall Major Adverse Cardiac Event, (MACE a composite endpoint of Cardiac Death, Myocardial Infarction and TLR) rate was 7.3% for the XIENCE V (PROMUS) Stent and 12.8% for the TAXUS Express Stent (p=0.004). In addition, stent thrombosis rates using the ARC (Academic Research Consortium) definite/probable definition were low for the XIENCE V (PROMUS) and the TAXUS Express Stents (1.3% and 1.7%, p=0.77).
"We are very pleased that both the TAXUS Express and PROMUS Stents
continue to perform so well in the SPIRIT III trial, adding to the
extensive body of clinical evidence reinforcing the excellent safety and
efficacy of the market-leading TAXUS Stent and the growing body of positive
clinical evidence for the PROMUS Stent at two years,"
