Overview
Brief Summary
This study aims to demonstrate that the BioFreedom™ Ultra Drug Coated Stent (DCS) is non-inferior to the BioFreedom™ DCS, with respect to in-stent late lumen loss, and that it has safety characteristics similar to the BioFreedom™ DCS.
Detailed Description
The LEADERS FREE IV trial is conducted to evaluate of the efficacy (QCA) and safety of the BioFreedom™ Ultra Drug Coated Stent in patients with High Bleeding Risk (HBR) and coronary artery disease undergoing Percutaneous Coronary Intervention. It is a prospective, multi-center, single blind (to patient), randomized, comparator trial, designed to randomize 444 HBR patients at approximately up to 7 centers in Malaysia. The primary objective is to confirm non-inferiority of the BioFreedom™ Ultra stent compared to BioFreedom™ DCS as measured by the difference in angiographically measured late lumen loss at 9 months, and the main secondary objective is to assess safety as measured by TLF and ST. 444 patients will be randomized 1:1 to either stent, allowing for a direct comparison, and will be followed up to 5 years to measure for late TLF and ST events.

Eligibility Criteria
Inclusion Criteria
- •Patients at high bleeding risk (HBR) with an indication for PCI who can tolerate at least one month of DAPT. This includes patients with stable angina, silent ischemia, acute coronary syndromes (ACS) (STEMI and NSTEMI), de novo lesions in native arteries with diameter stenosis \>70% by visual estimation and evidence of ischemia in the territory of the target vessel(s).
- •Patients meet ARC-HBR definition i.e at least 1 major or 2 minor criteria.
Exclusion Criteria
- •Pregnant and breastfeeding women
- •Age \<18 years old
- •Patients lacking capacity (i.e. patients suffering from dementia and others) to provide informed consent
- •Patients expected not to comply with 1 month DAPT
- •Active bleeding at the time of inclusion
- •Procedure requires the use of non-study stents, or alternative therapeutic options not followed by stent implantation (angioplasty only, atherectomy only)
- •Number of target lesions \>2
- •Patient requires a stent of diameter \<2.25mm
- •Patient requires a stent of diameter \>4.0mm
- •Isolated ostial lesions within 3 mm of the origin of LAD or LCx (left main lesions involving the ostia of the LAD and/or LCx are eligible)
