VANCOUVER, Sept. 22 /PRNewswire-FirstCall/ - Angiotech Pharmaceuticals, Inc. (NASDAQ: ANPI, TSX: ANP) announced that its corporate partner, Boston Scientific Corporation (NYSE: BSX), has released comprehensive data from the TAXUS ATLAS clinical program, a series of global, prospective, single-arm trials evaluating the TAXUS(R) Liberté(R) Paclitaxel-Eluting Stent System in a variety of lesions and patient groups. Five-year results from the TAXUS ATLAS trial and four-year results from the TAXUS ATLAS Small Vessel and Long Lesion trials continue to show significant advantages for the thin-strut TAXUS Liberté Stent when compared to the first-generation TAXUS(R) Express(R) Stent. Analysis of the data was presented by the Co-Principal Investigators of the TAXUS ATLAS trials, Mark A. Turco, M.D., Director of the Center for Cardiac and Vascular Research, Washington Adventist Hospital, and John A. Ormiston, M.D., Mercy Angiography Unit, Mercy Hospital, Auckland, New Zealand, at the Cardiovascular Research Foundation's annual Transcatheter Cardiovascular Therapeutics scientific symposium in Washington, D.C.

"The TAXUS ATLAS trials continue to reinforce the long-term safety and efficacy of the TAXUS Liberté Stent in a variety of complex lesions," said Dr. Turco. "The data showed sustained positive outcomes in workhorse lesions, significantly reduced rates of re-intervention in small vessels and important safety differences in long lesions. The ATLAS data suggest that improvements in stent design and a reduction in strut thickness may contribute to improved clinical outcomes for patients treated with the TAXUS Liberté Stent."

TAXUS ATLAS "Workhorse" Lesions

Data from 871 patients in the TAXUS ATLAS trial demonstrated that the durable safety and efficacy profile of the TAXUS Liberté Stent is maintained at five years in de novo coronary ("workhorse") lesions. In spite of more complex patients treated with the TAXUS Liberté Stent, the unadjusted data showed comparable clinical outcomes between the TAXUS Liberté Stent and a historical case-matched TAXUS Express(R) Stent control group. The study reported similar rates of target lesion revascularization (TLR) of 11.0 percent for the TAXUS Liberté Stent vs. 11.5 percent for the TAXUS Express Stent (p=0.72). Five-year data also showed comparable rates of cardiac death (5.1 percent for the TAXUS Liberté Stent vs. 4.4 percent for the TAXUS Express Stent, p=0.49) and overall myocardial infarction (MI) (7.6 percent for the TAXUS Liberté Stent vs. 8.4 percent for the TAXUS Express Stent, p=0.57). The rate of ARC(1) definite/probable stent thrombosis at five years was 3.0 percent for the TAXUS Liberté Stent vs. 2.7 percent for the TAXUS Express Stent (p=0.76).

TAXUS Atlas Small Vessel

Four-year data were presented from the TAXUS ATLAS Small Vessel trial, which is designed to evaluate the long-term safety and efficacy of the TAXUS Liberté Atom(TM) (2.25 mm) Stent compared to lesion-matched patients from the TAXUS V trial treated with either 2.25 or 2.5 mm bare-metal Express(R) Stents or the TAXUS Express(R) 2.25 mm Stent. The TAXUS Liberté 2.25 mm Stent showed significantly lower rates of TLR (10.8 percent vs. 23.8 percent, p=0.008), target vessel revascularization (or TVR, 16.5 percent vs. 31.7 percent, p=0.007), target lesion failure (or TLF, 15.4 percent vs. 30.2 percent, p=0.007) and major adverse cardiac events (or MACE, 21.6 percent vs. 36.5 percent, p=0.02) sustained at four years compared with the TAXUS Express 2.25 mm Stent and similar significant reductions compared to the bare-metal Express Stent group. All stents showed comparable rates of total death, cardiac death, MI and ARC definite/probable stent thrombosis.

"The TAXUS Liberté 2.25 mm Stent significantly reduced restenosis and maintained safety outcomes in small vessels compared to the TAXUS Express 2.25 mm Stent and Express bare-metal stents," said Dr. Ormiston. "Since TAXUS Liberté uses the same drug/polymer coating as TAXUS Express, I believe these improved clinical outcomes in small vessels likely result from the thinner struts and improved stent geometry of the TAXUS Liberté Stent."

TAXUS Atlas Long Lesion

Four-year data were also presented from the TAXUS ATLAS Long Lesion trial, which is designed to assess the safety and efficacy of the TAXUS Liberté Long (38 mm) Stent in patients with long coronary lesions compared to a case-matched patient cohort from the TAXUS IV and V trials treated with TAXUS Express Stents. In a subgroup analysis of patients treated with a single stent, the TAXUS Liberté Long Stent showed significantly reduced rates of target-vessel MI (2.6 percent vs. 12.9 percent, p=0.02) and target-vessel non-Q-wave MI (2.6 percent vs. 11.3 percent, p=0.03) compared to the TAXUS Express Stent at four years. Both stent groups demonstrated comparable rates of TLR, MACE and ARC definite/probable stent thrombosis.

"The TAXUS Liberté Long Stent maintained a continued long-term safety benefit in patients with long lesions, resulting in lower target vessel-related MI and a numerically lower rate of cardiac death compared to the TAXUS Express Stent," said Dr. Turco.
