Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. 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).
2. Patients meet ARC-HBR definition i.e at least 1 major or 2 minor criteria.

Exclusion Criteria

1. Pregnant and breastfeeding women
2. Age \<18 years old
3. Patients lacking capacity (i.e. patients suffering from dementia and others) to provide informed consent
4. Patients expected not to comply with 1 month DAPT
5. Active bleeding at the time of inclusion
6. Procedure requires the use of non-study stents, or alternative therapeutic options not followed by stent implantation (angioplasty only, atherectomy only)
7. Number of target lesions \>2
8. Patient requires a stent of diameter \<2.25mm
9. Patient requires a stent of diameter \>4.0mm
10. 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)
11. Patient has known left ventricular ejection fraction (LVEF) \<30% (LVEF may be obtained at the time of the index procedure if the value is unknown and the investigator believes it is necessary)
12. Patient with chronic total occlusion(s) as target lesion(s)
13. Severe calcification that might prevent sufficient expansion of the DES, unless pre-treated with a plaque modification device such as cutting balloon, scoring balloon or intravascular lithotripsy.

Note: Use of rotational or orbital atherectomy is also permitted.
14. Cardiogenic shock
15. Compliance with long-term single anti-platelet therapy unlikely
16. Known hypersensitivity or contraindication to aspirin, clopidogrel (or to any other P2Y12 inhibitor if applicable), cobalt chromium, stainless steel, zinc, Biolimus A9™ or a sensitivity to contrast media, which cannot be adequately pre-medicated
17. Any PCI during the previous 12 months
18. Participation in another clinical study (12 months after index procedure)
19. Patients with a life expectancy of \<12 months
