Brief Summary:
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.

Drug Information available for: Sirolimus

Arm Intervention/treatment
Active Comparator: Abbott Laboratories Xience
Subjects assigned to Abbott Laboratories Xience can be treated with either the Xience Prime or Xience Xpedition drug eluting stent (DES).
Device: Abbott Laboratories Xience
Experimental: Biotronik Orsiro
Subjects assigned to Biotronik Orsiro will be treated with Biotronik Orsiro
Device: Biotronik Orsiro

Primary Outcome Measures :
  1. Target Vessel Failure [ Time Frame: 12 months post index procedure ]

Secondary Outcome Measures :
  1. 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 ]
  2. 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 ]
  3. 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 ]

Layout table for eligibility information
Ages Eligible for Study:   18 Years to 80 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

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
