Angiotech Pharmaceuticals announces FDA approval of TAXUS(R) Liberte(R) Long Stent

VANCOUVER, July 16 /PRNewswire-FirstCall/ - Angiotech Pharmaceuticals, Inc. (NASDAQ: ANPI, TSX: ANP) today announced that its corporate partner, Boston Scientific Corporation (NYSE: BSX) has received approval from the U.S. Food and Drug Administration (FDA) to market its TAXUS(R) Liberte(R) Long Paclitaxel-Eluting Coronary Stent System, a next-generation drug-eluting stent (DES) designed for long lesions. At 38 mm, it is the longest available DES, providing doctors an option that can potentially reduce the number of stents used in more complex cases, simplifying procedures and reducing costs. It affords a more efficient treatment option for the estimated 8 to 10 percent(1) of patients with long lesions. Boston Scientific plans to launch the product in the U.S. next month. It received CE Mark approval in 2007.

"The TAXUS Liberte Long Stent offers physicians and patients distinct advantages compared to using two overlapping drug-eluting stents," said Mark Turco, M.D., FACC, FSCAI, Director of the Center for Cardiac Vascular Research at Washington Adventist Hospital, Takoma Park, Maryland. "In the ATLAS Long Lesion Trial, the 38 mm TAXUS Liberte Stent significantly reduced myocardial infarction when compared to the TAXUS(R) Express(R) Stent, making the TAXUS Liberte Long Stent an attractive option for interventional cardiologists faced with long, challenging lesions."

The TAXUS ATLAS Long Lesion Trial reported a significant 79 percent reduction in the rate of nine-month myocardial infarction for the TAXUS Liberte Long Stent as compared to the TAXUS Express Stent control (1.3% vs. 6.3%, p=0.026). At two years, the composite measure of cardiac death or myocardial infarction showed a significant 63 percent reduction for the TAXUS Liberte Long Stent compared to the TAXUS Express Stent (3.5% vs. 9.4%, p=0.0426). The rate of stent thrombosis at two years was zero percent for the TAXUS Liberte Long Stent and 0.8 percent for the TAXUS Express Stent(2).

"Today's approval of the TAXUS Liberte Long Stent, along with the approval of the TAXUS Liberte Atom(TM) Stent in May, demonstrates the strength and breadth of the paclitaxel platform," said Dr. William Hunter, President and CEO of Angiotech. "We are pleased with the progress that Boston Scientific continues to make with TAXUS stents."

Boston Scientific has the industry's widest range of coronary stent sizes. The TAXUS Liberte Stent Series is now available in 92 sizes, ranging from 2.25 mm to 4.0 mm in diameter and from 8 mm to 38 mm in length.

TAXUS Stents have been evaluated by the industry's most extensive randomized, controlled clinical trial program, with follow-up to five years in some cases. These trial results have been supplemented by data on more than 35,000 patients enrolled in post-approval registries. To date, approximately 11 million Boston Scientific stents have been implanted globally, making them the world's most frequently used stents.

        and ARRIVE 1 and 2 registries.

    (2) In the TAXUS ALTAS Long Lesion Trial, the TAXUS Liberte Long (38mm)
        Stent met its primary endpoint of non-inferiority to the TAXUS
        Express control Stent in nine-month percent diameter stenosis (31.7%
        vs. 32.6%, p=0.71) and reported a 36 percent reduction in
        MACE (9.4% vs. 14.8%, p=0.16).
