Prospective, multinational trial CEC and DSMB oversight Imaging Core Lab analyses Primary safety endpoint: 12-month event-free survival Freedom from death, amputation, target lesion revascularization, or worsening Rutherford score (by 2 classes or to class 5 or 6) Per-protocol cohort, Kaplan-Meier p-values from log-rank test Primary effectiveness endpoint: 12-month primary patency Duplex ultrasonography, patent = PSVR < 2.0 (or angiography if available, patent = diameter stenosis < 50%) Intent-to-treat cohort, Kaplan-Meier p-values from log-rank test Ongoing follow-up through 5 years Zilver PTX Randomized Trial
Effectiveness EndpointPrimary Patency (PSVR < 2.0) 83.1% 76.7% Zilver PTX 65.3% Optimal PTA (p < 0.01 vs. Zilver PTX) 60.0% 32.8% PTA (p < 0.01 vs. Zilver PTX) 29.8%
Patency (PSVR < 2.0) for Primary Zilver PTX vs. Standard Care (PTA with Provisional Bare Stenting) 83.1% 76.7% Zilver PTX 67.0% Standard Care (p < 0.01 vs. Zilver PTX) 61.0%
Patency (PSVR < 2.0) for Zilver PTX vs. BMSIs the drug effect significant? 89.9% 83.0% Zilver PTX 73.0% Bare Zilver (p = 0.01 vs. Zilver PTX) 65.9%
Conclusions • Largest prospective, randomized trial for endovascular treatment of symptomatic femoropopliteal PAD (479 patients) • Low Zilver stent fracture rate (0.9%) through 12 months • Primary Zilver PTX stenting resulted in • Significantly better 12-month patient safety compared to PTA • Significantly higher 12-month patency compared to: • PTA and optimal PTA • Standard care (PTA with provisional BMS) • Provisional Zilver PTX patency (89.9%) significantly higher than provisional BMS patency (73.0%) • PTX coating reduced 12-month restenosis rate by 63%
