Brief Summary

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

A prospective, multi-center, open-label, randomized controlled, and superiority trial. The trial will compare clinical outcomes between discontinuation of antiplatelet agent and continuation of antiplatelet agent in HBR patients with chronic coronary syndrome treated by DCB angioplasty and standard duration of DAPT, followed by maintenance of single antiplatelet agent without clinical event for at least 1 year from the index procedure.

Detailed Description

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

In patients with chronic coronary syndrome, the benefit of percutaneous coronary intervention (PCI) has been controversial for a survival benefit while reducing the risk of spontaneous myocardial infarction (MI) or anginal symptoms. Therefore, unlike patients with acute coronary syndrome, routine PCI with drug-eluting stents (DES) for patients with chronic coronary syndrome should be individualized, considering the risk of long term possibility of stent failure and the need for maintaining dual antiplatelet therapy (DAPT) for certain period due to permanent vascular implant and increased risk of bleeding, especially in patients with high bleeding risk (HBR). Drug-coated balloon (DCB), a novel treatment strategy, which has benefit of having shorter antiplatelet therapy duration due to the absence of metallic scaffolds and polymers, could be an alternative treatment for patients with chronic coronary syndrome, especially in patients with HBR. Given the expanding indications for DCB including de novo coronary artery lesions, shorter duration of DAPT, and potentially reduced risk of bleeding might be a reasonable treatment strategy in patients with HBR.

In current guidelines, standard duration of DAPT after PCI is recommended for 1 to 3 months in patients with HBR. Then, it is recommended as Class IA recommendation for maintaining single antiplatelet agent for lifelong as a secondary prevention, regardless of the devices used during PCI and the risk of patients' bleeding risk. However, it should be noted that the supporting evidence for lifelong maintenance of single antiplatelet agent were derived from previous randomized controlled trials conducted in patients with acute myocardial infarction or stroke. In addition, the supporting evidence for lifelong maintenance of single antiplatelet agent after PCI was derived from the recent randomized controlled trials using metallic stents including bare metal stent, 1st generation DES, or 2nd generation DES. The gap in the evidence is that no previous trial evaluated the need of lifelong maintenance of single antiplatelet agent in HBR patients with chronic coronary syndrome treated by DCB angioplasty after standard duration of DAPT. Furthermore, although recent trial have shown that long-term antiplatelet monotherapy with clopidogrel demonstrated better clinical outcomes than antiplatelet monotherapy with aspirin in patients with chronic coronary syndrome undergoing PCI with DES, there has been scarce data regarding long-term antiplatelet therapy for HBR patients with chronic coronary syndrome treated by DCB angioplasty after standard duration of DAPT.

On this background, the current trial aims to compare clinical outcomes between discontinuation of antiplatelet agent and continuation of antiplatelet agent in HBR patients with chronic coronary syndrome treated by DCB angioplasty and standard duration of DAPT, followed by maintenance of single antiplatelet agent without clinical event for at least 1 year from the index procedure. Having this evidence will be able to more establish the evidence for the post-adjunctive medical treatment in patients with HBR after DCB angioplasty.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Discontinuation of antiplatelet agent group

In this group, antiplatelet monotherapy will be discontinued at the time of randomization. Randomization will be performed at 1 year from the index procedure using DCB angioplasty, standard duration of DAPT (1-3 months), and maintenance of antiplatelet monotherapy at least 1 year from the index procedure in patients with HBR and chronic coronary syndrome. In patients who are still under DAPT at 1 year from index DCB angioplasty, all antiplatelet agents will be discontinued after randomization.

Group Type EXPERIMENTAL

Discontinuation of antiplatelet agent group

Intervention Type OTHER

In this group, antiplatelet monotherapy will be discontinued at the time of randomization. Randomization will be performed at 1 year from the index procedure using DCB angioplasty, standard duration of DAPT (1-3 months), and maintenance of antiplatelet monotherapy at least 1 year from the index procedure in patients with HBR and chronic coronary syndrome. In patients who are still under DAPT at 1 year from index DCB angioplasty, all antiplatelet agents will be discontinued after randomization.

Continuation of antiplatelet agent group

In this group, lifelong antiplatelet monotherapy will be continued after the time of randomization. Randomization will be performed at 1 year from the index procedure using DCB angioplasty, standard duration of DAPT (1-3 months), and maintenance of antiplatelet monotherapy at least 1 year from the index procedure in patients with HBR and chronic coronary syndrome. In patients who are still under DAPT at 1 year from index DCB angioplasty, DAPT will be changed to single antiplatelet therapy (aspirin or clopidogrel). The choice between aspirin or clopidogrel will be determined by the physician's discretion.
