Brief Summary:

BIOFLOW-DAPT is a prospective, multi-center, international, two-arm randomized controlled clinical study.

A total of 1'948 subjects will be randomized 1:1 to receive either Orsiro Mission or Resolute Onyx. After index procedure, all patients will receive DAPT (ASA + P2Y12 inhibitor) for 30 days, followed by monotherapy with either P2Y12 inhibitor or ASA only until the end of the study.

Clinical follow-up visits will be scheduled at 1, 6 and 12 months post-procedure.

Arm Intervention/treatment
Experimental: Orsiro Device: Percutaneous coronary intervention
It's a non-surgical procedure that uses a catheter to place a stent into a coronary blood vessel in order to open up the vessel.

Active Comparator: Resolute Onyx Device: Percutaneous coronary intervention
It's a non-surgical procedure that uses a catheter to place a stent into a coronary blood vessel in order to open up the vessel.

Exclusion Criteria:

  1. Subject who previously experienced a stent or scaffold thrombosis in any coronary vessel
  2. Subject has a known allergy to all types of P2Y12 inhibitor (Clopidogrel, Ticagrelor, Prasugrel, Ticlopidine and Cangrelor; thus preventing the use of the appropriate P2Y12 inhibitor), aspirin, both heparin and bivalirudin, L-605 cobalt-chromium (Co-Cr) alloy or one of its major elements (cobalt, chromium, tungsten, nickel), molybdenum, platinum and irridium, silicon carbide, PLLA,polymers, mTOR inhibiting drugs such as zotarolimus or sirolimus, or contrast media
