DEB Versus 2nd Generation DES in Patients With In-Scaffold Restenosis of

Status Suspended

Clinical Trial Summary

The aim of the study is to compare angiographic outcomes following revascularization using drug-eluting balloon (DEB) versus 2nd generation drug-eluting stent (DES) in treatment of Bioresorbable Vascular Scaffold Restenosis.

Clinical Trial Description

The bioresorbable vascular scaffold (BRS) has been emerged as new therapeutic option in percutaneous coronary intervention for coronary artery disease. Although 2nd generation drug-eluting stent (DES) has enhanced the efficacy and safety of DES, However, along with the widespread use of this newer generation DES in most clinical conditions, including high-risk patients with more complicated lesion profiles, ISR has continued to be a major concern, even in the era of newer generation DES. In this regards, the concept of BRS has introduced and has showed promising results. Nevertheless, previous reports showed that even BRS has not been free from restenosis, leading target lesion revascularization up to 7.4% during 3-year follow up. Currently, previous researches which comparedsafety and efficacy of treatment options for ISR lesion showed similar clinical outcomes following 2 representative options, namely, drug-eluting balloon or drug-eluting stent. In this regards, current European Society of Cardiology/European Association for Cardiothoracic Surgery (ESC/EACTS) guidelines recommend drug-eluting balloon (DEB) and 2nd generation DES as class IA recommendations for the treatment of BMS or DES-ISR. However, all the previous reports evaluated the ISR of metallic stents, and there has been no evidence for treatment option for BRS ISR. Therefore, the Smart Angioplasty Research Team: Safety and Efficacy of Drug-Eluting Balloon versus 2nd Generation Drug-Eluting Stent in Treatment of In-Bioresorbable Vascular Scaffold Restenosis (SMART-BRS-ISR) trial will randomly allocate patients with BRS ISR into DEB or 2nd generation DES and compare safety and efficacy of both treatment options. ;

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.
