A Randomized Trial Comparing the Agent Paclitaxel-Coated PTCA Balloon Catheter vs SeQuent Please Drug Eluting Balloon Catheter for the Treatment of a Small Vessel De Novo Native Coronary Artery Lesion.

Study Overview

Detailed Description

Primary objective is to evaluate the safety and effectiveness of the Agent ™ Paclitaxel-Coated PTCA Balloon Catheter for the treatment of Japanese subjects with a small vessel de novo native atherosclerotic coronary artery lesion or in-stent restenosis (ISR) of a previously treated lesion.

Primary endpoint: Target Lesion Failure (TLF) rate at 6 months post index-procedure. TLF is defined as any ischemia driven revascularization of the target lesion (TLR), myocardial infarction (MI, Q-wave and non-Q-wave) related to the target vessel, or cardiac death.

    • ≥90% diameter stenosis.
    • Stenosis that is considered a cause of stable effort angina (Only when it's without confirmation of significant stenosis).
    • Stenosis that is confirmed a cause of functional ischemia with any test.

    • Target lesion must be a de novo lesion located in a native coronary artery with visually estimated stenosis ≥75% and <100% (This applys for SV trial. For ISR substudy: Target lesion for ISR must be in-stent restenosis of a previously-treated lesion located in a native coronary artery with visually estimated stenosis ≥75% and <100%.).
    • Coronary anatomy is likely to allow delivery of an investigational device to the lesions.
    • Target lesion must be successfully pre-dilated.
  9. Planned treatment of 2 coronary artery lesions in 2 vessels may be treated (For SV trial, up to two lesions per vessel can be treated. For ISR substudy, single lesion per vessel can be treated.).
