Paclitaxel-Coated Balloon Versus Zotarolimus-Eluting Stent for Treatment

Status Active, not recruiting

Clinical Trial Summary

Coronary restenosis has been one of the main reasons affecting the prognosis of patients with coronary artery disease (CAD) after percutaneous coronary intervention (PCI). With drug-eluting stents (DES), which elutes an antiproliferative drug to the vessel wall and reduces the restenosis rate; however, the incidence of restenosis is still about 10%. The late stent thrombosis and restenosis, with a hazard of nearly 2% per year after implantation, remained a concern and motivated the development of drug-coated balloons (DCB). DCB angioplasty has the following advantages compared with DES implantation: Firstly, the drug in DCB is uniformly distributed and released; whereas the drug release of DES via stent platform is uneven -85% of the vascular wall is not covered by the stent strut. Secondly, there is no alloy in the vessel after DCB angioplasty, while the coronary stent platform and polymer might cause temporal or persistent inflammatory response leading to intimal hyperplasia. Finally, there is no metal cage restraining vessel motion after DCB, the physiological function of coronary arteries would be maintained. Studies with the strategy of DCB angioplasty with bailout stenting have demonstrated safety and efficacy for the small-vessel disease. The application of DCB in large vessels with de novo lesions is still to be investigated. The DEBUT study showed that in high bleeding risk patients aimed using only 1-month DAPT, DCB was superior to BMS in terms of MACE [MACE (cardiovascular mortality, nonfatal myocardial infarction or revascularization of ischemia-reperfusion target lesions)] at 9-month follow-up. However, there is still a lack of evidence comparing the DCB versus DES in large vessels with de novo lesions. The current study aims to investigate if in patients undergoing PCI for de novo stenoses in large vessels, DCB is non-inferior to DES.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
