Randomized MicroPort's Firehawk DES Versus Xience V: TARGET I Trial

A Prospective Multi-center Randomized Trial Assessing the Safety and Effectiveness of Biodegradable Polymer Target Release Rapamycin-Eluting STent vs. XIENCE V Everolimus-Eluting Stent for the Treatment of Coronary Artery Disease

The purpose of this study is to evaluate new generation drug eluting stent (DES) of MicroPort of its safety, efficacy and delivery system in treating CAD.

The primary endpoint is in-stent late lumen loss after 9 months of the stent implantation. The secondary endpoint is in-stent percent diameter stenosis.This study is based on non-inferior assumption (vs. Xience V), requiring both endpoints reach statistical significance. Prespecified OCT follow-up is planned at 3-Year after index procedure at 3 chosen hospitals.

Inclusion Criteria:

• Age 18-75, male or women who are not pregnant
• Evidence of non-symptomatic ischemia, stable or non-stable angina or past heart attack cases
• Target lesion is primary, single artery and single lesion of coronary artery
• Target lesion vessel length ≤24mm, diameter 2.25mm-4.0mm
• Lesion diameter stenosis ≥70%
• Candidates understand the study, willing to sign Consent of Agreement and to willing to accept follow-up For long lesion group, at least one target lesion length ≥28mm，diameter 2.5mm-4.0mm, and one lesion needs to implant 33mm 0r 38mm long stent

Exclusion Criteria:

• Acute heart attack within one week
• Chronic complete stenosis (TIMI 0), left main lesion, three branches need to treat, branch vessel diameter ≤2.5mm and bypass lesion

• LLL between -0.01~0.2mm
• No mix-implanted stent
• No more than one bail-out stent
• No TLR occurred at 3 years after PCI
• The target vessel able to deliver the OCT catheter
