Leave Nothing Behind Study Which Compares DCB With Bail Out BRS Versus BRS Strategy Alone

The goal of this study is to investigate the equivalence in early and long-term efficacy between the two "Leave nothing behind strategies" (Drug-Coated Baloon \[DCB\] strategy with bail-out BioResorbable Scaffold \[BRS\] versus BRS strategy) of de-novo native coronary artery lesions in a relatively young Percutaneous Coronary Intervention (PCI) population, to be more specific, Patients with Chronic Coronary Syndromes (CCS) and Acute Coronary Syndrome (ACS) (Non-ST-segment Elevation Myocardial Infarction \[NSTEMI\] and Unstable angina) between 18-68 years of age scheduled for PCI. The main questions aim to answer are: DCB strategy with bail-out BRS implantation has equivalent clinical outcomes at 12 months compared to BRS strategy? DCB strategy with bail-out BRS implantation has noninferior angiographic in-segment net gain at 13 months compared to BRS strategy? DCB strategy with bail-out BRS implantation has equivalent clinical outcomes at 60 months compared to BRS strategy? Participants will be followed at: 1. st FU visit - 1 month (in hospital) 2. nd FU visit - 6 months (telephone) 3. rd FU visit - 365 days±15 days (telephone) - 1Y Primary efficacy endpoint 4. th FU visit - 395 days±15 days (in hospital) co-primary efficacy endpoint for the angiographic substudy 5. th FU visit - 730 days±30 days (telephone call) - 2Y 6. th FU visit - 1095 days±30 days (telephone call) - 3Y 7. th FU visit - 1460 days±30 days (telephone call) - 4Y 8. th FU visit- 1825 days±30 days (telephone call) - 5Y

The Leave Nothing Behind Study is an is an investigator-initiated trial. The Primary efficacy endpoint is target-vessel failure (TVF), defined as the composite of cardiovascular death, target-vessel myocardial infarction or ischemia-driven target-vessel revascularization (TVR) at 12 months. Co-primary efficacy endpoint (angiographic substudy) is the in-segment net gain at 13 months. Investigators aim to enroll 2256 patients in the main study and 196 patients in the angiographic substudy.
