Summary

DCB-HBR trial is prospective, multi-center, open-label, randomized controlled, noninferiority trial. The aim of the study is to compare clinical outcomes of drug-coated balloon (DCB) with drug-eluting stent (DES) for treatment of de-novo coronary lesion in patients with high bleeding risk (HBR).

Detailed description

Second-generation DES is the standard of care for patients with coronary artery disease who are deemed eligible for percutaneous coronary intervention (PCI). Despite many advantages, DES inevitably accompany disadvantages such as the occurrence of late stent thrombosis and the need for maintaining dual antiplatelet (DAPT) for certain period due to permanent vascular implant, which lead to both increased ischemic and bleeding events. As an alternative to DES, drug-coated balloon (DCB), a novel treatment strategy, which has benefit of having shorter DAPT maintenance duration due to the absence of metallic scaffolds and polymers, has been introduced. Based on meta-analysis based on many randomized clinical trials (RCT), its use has been established in in-stent restenosis of bare-metal stents (BMS) and DES. Furthermore, recently published RCT demonstrated efficacy and safety of DCB in de-novo coronary lesions in small vessels with reference vessel size\<3.0mm. However, studies exploring the feasibility of DCB in de-novo coronary artery stenosis beyond small vessels are limited. Furthermore, there is scarce data comparing DCB with DES in patients with de-novo coronary artery stenosis and high bleeding risk (HBR), a situation in which long-term maintenance of DAPT is a clinical dilemma. In previous BASKET-SMALL 2 trial, DCB showed noninferiority to DES in patients with de-novo coronary artery stenosis and small vessel disease. However, this trial was conducted in non-HBR patients, and the number of participated patients was insufficient. In another RCT, DEBUT trial exclusively enrolled patients with HBR and de-novo coronary artery stenosis. Although the DEBUT trial showed superiority of DCB angioplasty over implantation of BMS to treat de-novo coronary artery stenosis in patients with HBR, the results could not be applicable in contemporary practice because BMS has been no longer in clinical use. Recently, multiple RCTs have proved short-term DAPT (1-3 months) has comparable efficacy to longer term DAPT in HBR patients using latest second-generation DES. On this background, the current trial aims to compare clinical outcomes between DCB and DES to treat de-novo coronary artery stenosis in patients with HBR receiving guideline-directed short-term DAPT.
