Boston Scientific Corporation Safety Profile of TAXUS(R) Liberte(TM) Stent System Highlighted in World’s Largest Stent Registry

NATICK, Mass. and VIENNA, Austria, Sept. 2 /PRNewswire-FirstCall/ -- Boston Scientific Corporation today announced one-year results from the European and Intercontinental launch phases of its TAXUS OLYMPIA registry. The first 7,124 patient cohort of the nearly 23,000 enrolled provided positive safety data on the TAXUS(R) Liberate(TM) coronary stent system in complex, real-world patients, as announced at the European Society of Cardiology Congress in Vienna, Austria.

The one-year results demonstrated a low overall 3.9 percent rate of TAXUS Liberte stent related cardiac events, including cardiac death (1.1 percent), myocardial infarction (0.9 percent), and TAXUS Liberte stent related re-intervention of the target vessel (2.5 percent). The one-year stent thrombosis rate was 0.8 percent, which is consistent with safety data from other DES registries.

In the diabetic subset (2,380 patients), OLYMPIA reported a low 4.4 percent rate of overall TAXUS Liberte stent related cardiac events, including cardiac death (1.9 percent), and myocardial infarction (0.8 percent). TAXUS Liberte stent related re-interventions (2.3 percent) and stent thrombosis (0.7 percent) were both lower for the high-risk diabetic patient group than the rates for the overall population.

“The OLYMPIA registry continues to show impressive results, especially given the high degree of complex patient and lesions from real-world practice,” said Martyn Thomas, M.D., F.R.C.P., Director of Invasive Cardiology, Kings College Hospital, London, and one of the coordinating investigators of the registry. “The data show consistency with initial results and with data from other TAXUS clinical trials and registries, offering further evidence that the TAXUS Liberte stent system continues to show positive safety outcomes in real-world use.”

“The one-year OLYMPIA data show excellent outcomes with the TAXUS Liberte stent system across a large patient population with a broad range of lesion complexity, including diabetics who have typically demonstrated increased event rates,” said Jeff Goodman, President of Boston Scientific International. “Our second-generation stent platform - TAXUS Liberte - offers exceptional deliverability and is the only current drug-eluting stent geometry designed specifically for drug elution. The strong clinical results, excellent performance in diabetics and solid physician preference have allowed TAXUS Liberte to take a clear leadership role in European and Intercontinental markets.”

The global, prospective OLYMPIA registry is the world’s largest DES registry and plans to enroll up to 26,000 patients from more than 400 centers worldwide. OLYMPIA is designed to analyze real-world clinical outcomes data for Boston Scientific’s second-generation TAXUS Liberte paclitaxel-eluting stent system in the treatment of patients with coronary artery disease.

The OLYMPIA European and Intercontinental launch phases consisted of diverse and high-risk patient populations, reflecting complex usage patterns in “real-world” clinical practices. A majority of patients exhibited complex lesions or clinical characteristics, including, multi-vessel disease (57.7 percent), prior myocardial infarction (MI) (37.3 percent), acute MI (17.8 percent), multiple stents (32.9 percent), type B2/C lesions (56.6 percent) and diabetes (33.4 percent). Of the first 7,124 patients enrolled, 92.5 percent (6,593 patients) were available for evaluation at one year.

Patients with a single vessel treated with only one TAXUS Liberte stent were considered simple use patients and comprised 27.6 percent of the total. Complex use patients comprised 72.4 percent of the population (5,157 patients) and included patients with acute MI, small vessels, long lesions, in-stent restenosis, and bifurcations, representing lesions not studied in the TAXUS IV and TAXUS ATLAS pivotal randomized controlled trials. Despite the higher complexity, patients in this group demonstrated an overall TAXUS Liberte stent related cardiac event rate of 4.6 percent and a stent thrombosis rate of 1.0 percent.

CAUTION: The TAXUS Liberte stent is an investigational device and is not for sale in the United States.
