1 SIRIUS: A U.S. Multicenter, Randomized, Double-Blind Study of the SIRolImUS-Eluting Stent in De Novo Native Coronary Lesions Presented at TCT 2002

2 De Novo Coronary Lesions
SIRIUS: Study Design n = 1,101 patients Control Bx VELOCITYTM n = 545 De Novo Coronary Lesions Diameter: mm Length: mm Sirolimus-eluting Bx VELOCITYTM n = 556 Primary Endpoint: Target vessel failure (TVF) = cardiac death, MI or TVR (FU at 9 months) Angiographic Substudy: First 850 pts (FU at 8 months) IVUS Substudy: 250 pts at selected sites (FU at 8 months) TCT 2002

3 All Randomized Patients n = 1,101
SIRIUS: Study Flow All Randomized Patients n = 1,101 De-registered Sirolimus-eluting Bx VELOCITYTM n = 23 De-registered Control Bx VELOCITYTM n = 20 Sirolimus-eluting Bx VELOCITYTM n = 533 Control Bx VELOCITYTM n = 525 Angio FU at 8 Months = 85.4% Clinical FU at 9 Months = 95.7% Angio FU at 8 Months = 84.7% Clinical FU at 9 Months = 95.8% TCT 2002
