BIOFLOW-IV is a prospective, international, multicenter, randomised controlled trial. The purpose of this trial is to compare the Biotronik Orsiro drug eluting stent system with the Xience Prime / Xience Xpedition (Xience)drug eluting stent system in de novo coronary lesions. The study is powered for non-inferiority with respect to Target Vessel Failure(TVF)at 12 months.

time frame: 12 months post index procedure

Secondary Outcomes

Rate of clinically-driven target lesion revascularization (TLR)
time frame: 1-month, 6-month, 12-month, 2-year, 3-year, 4-year and 5-year
Rate of clinically-driven target vessel revascularization (TVR)
time frame: 1-month, 6-month, 12-month, 2-year, 3-year, 4-year and 5-year
Rate of target lesion failure (TLF), defined as composite of cardiac death, target vessel Q-wave or non-Q wave myocardial infarction (MI), emergent coronary artery bypass graft (CABG), any clinically-driven TLR
time frame: 1-month, 6-month, 12-month, 2-year, 3-year, 4-year and 5-year

Eligibility Criteria

All participants from 18 years up to 80 years old.

Main Inclusion Criteria: - Subject must provide written informed consent - The target reference vessel diameter (RVD) is ≥ 2.50 mm and ≤ 3.75 mm assessed either visually or by online QCA. - Target lesion length is ≤ 26 mm (assessed either visual estimate or by online QCA) and can be covered by one study stent - Single de novo lesion with ≥ 50% and < 100% stenosis in up to 2 coronary arteries Main Exclusion Criteria: - Subject has evidence of myocardial infarction within 72 hours prior to the index procedure - Planned intervention of non-target vessel(s) within 30 days after the index procedure - Planned intervention of target vessel(s) after the index procedure - Target lesion is located in the left main - Target lesion is located in or supplied by an arterial or venous bypass graft - Target lesion involves a side branch > 2.0 mm in diameter by visual estimate or by online QCA - Proximal or distal to the target lesion located stenosis that might require future revascularization or impede run off
