Thin Strut Sirolimus-eluting Stent in All Comers Population vs Everolimus-eluting Stent

Study Overview
=================
Brief Summary
-----------------
The primary objective of this study is to compare the performance of SUPRAFLEX to that of XIENCE in an all-comers patient population with symptomatic ischemic heart disease. The patients will be followed through 3 years for major clinical events.

Detailed Description
-----------------
This is a prospective, randomized, 1:1 balanced, controlled, single-blind, multi-center study comparing clinical outcomes at 12 months between SUPRAFLEX and XIENCE in a Real world, all comers patient population (patients with symptomatic coronary artery disease including patients with chronic stable angina, silent ischemia, and acute coronary syndromes, who qualify for percutaneous coronary interventions). The objective is to compare the SUPRAFLEX SES with the XIENCE EES with respect to target lesion failure (TLF) at 12 months in a non-inferiority trial in a real world patient population. All patients will be (at minimum) contacted at 30 days, 6 months, and 12 months post procedure to assess clinical status and adverse events. The 30 day and 12 month will be a clinic visit. All patients will have annual contact through 3 years follow-up to assess clinical status and adverse events.

Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: All comers patients: Male or female patients 18 years or older; Presence of one or more coronary artery stenoses of 50% or more in a native coronary artery or in a saphenous venous or arterial bypass conduit suitable for coronary stent implantation. The vessel should have a reference vessel diameter ranging from ≥2.25 mm to ≤4.5 mm (no limitation on the number of treated lesions, vessels, or lesion length); All lesions of the patient must comply with the angiographic inclusion criteria. The patient (or legal guardian) understands the trial requirements and the treatment procedures and provides written informed consent before any trial-specific tests or procedures are performed. Patient is willing to comply with all protocol-required evaluations. Exclusion Criteria: Known pregnancy or breastfeeding at time of randomization; Known contraindication or hypersensitivity to sirolimus, everolimus, cobalt-chromium, or to medications such as aspirin, heparin, bivalirudin, and all of the following four medications: clopidogrel bisulfate, ticlopidine, prasugrel, ticagrelor; Any PCI treatment within 6 months (<6 months) prior to the index procedure. Concurrent medical condition with a life expectancy of less than 12 months. The patient is unwilling/ not able to return for outpatient clinic at 12 months follow-up. Currently participating in another trial and not yet at its primary endpoint.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: SUPRAFLEX<br>Percutaneous Coronary Intervention with the SUPRAFLEX Sirolimus Eluting Bioabsorbable Polymer Coronary Stent System. It is a balloon expandable sirolimus eluting stent with an bioabsorbable polymer coating. | Device: SUPRAFLEX<br>* Percutaneous Coronary Intervention<br>|
