Kaplan-Meier Primary Patency Rate: 12-Month Results chart

CLINICAL-DRIVEN TLR RATE

In IMPERIAL RCT and as reported in The Lancet, 1-year ITT, CEC adjudicated mortality rates were 2.1% (6/292) for Eluvia and 4.0% (6/150) for Zilver PTX (p=0.23).
*Kaplan Meier Estimate; Primary patency as determined by duplex ultrasound (DUS) Peak Systolic Velocity Ratio (PSVR) is ≤ 2.4 at the 12-month follow-up visit, in the absence of clinically-driven TLR or bypass of the target lesion.

† Log-rank p-value compares the entire K-M curves from time zero to full one year follow-up window.
1. IMPERIAL Trial: A global randomized controlled multi-center trial with 2:1 randomization of the Eluvia™ Drug-Eluting Stent against Cook Medical’s Zilver™ PTX™ Stent, single-blind, non-inferiority design; independent core lab adjudication. Superiority determined in a post hoc analysis that was specified prior to unblinding. 12-Month Primary Patency rate of 86.8% in the Eluvia arm vs. 77.5% in the Zilver PTX arm (p-value = 0.0144).

IMPERIAL Trial Design

Global multi-center, 2:1 randomization against Cook Medical’s Zilver™ PTX™ Stent, controlled, single-blind, non-inferiority trial; core lab adjudicated
  • 465 (RCT) patients across 64 sites
  • 5-year follow-up
  • Degree of stenosis ≥ 70% (visual angiographic assessment)
  • Vessel diameter ≥ 4 mm and ≤ 6 mm
  • Total lesion length ≥ 30 mm and ≤ 140 mm
