EVOLVE II QCA: A Prospective, Multicenter Trial to Assess the SYNERGY Stent System for the Treatment of Atherosclerotic Lesion(s)

The purpose of this study is to evaluate 9 month angiographic and intravascular ultrasound (IVUS) data for the SYNERGY Everolimus-Eluting Platinum Chromium Coronary Stent System (SYNERGY Stent System) in the treatment of subjects with atherosclerotic lesion(s) ≤34 mm in length (by visual estimate) in native coronary arteries ≥2.25 mm to ≤4.0 mm in diameter (by visual estimate).

Inclusion criteria

  • Subject must be at least 18 years of age
  • Subject (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
  • For subjects less than 20 years of age enrolled at a Japanese site, the subject and the subject's legal representative must provide written informed consent before any study-specific tests or procedures are performed
  • Subject is eligible for percutaneous coronary intervention (PCI)
  • Subject has symptomatic coronary artery disease with objective evidence of ischemia or silent ischemia
  • Subject is an acceptable candidate for coronary artery bypass grafting (CABG)
  • Subject is willing to comply with all protocol-required follow-up evaluation

Angiographic Inclusion Criteria (visual estimate)

  • Target lesion(s) must be located in a native coronary artery with a visually estimated reference vessel diameter (RVD) ≥2.25 mm and ≤4.0 mm
  • Target lesion(s) length must be ≤34 mm (by visual estimate)
  • Target lesion(s) must have visually estimated stenosis ≥50% and <100% with thrombolysis in Myocardial Infarction (TIMI) flow >1 and one of the following (stenosis ≥70%, abnormal fractional flow reserve (FFR), abnormal stress or imaging stress test, or elevated biomarkers prior to the procedure)
  • Coronary anatomy is likely to allow delivery of a study device to the target lesions(s)
  • The first lesion treated must be successfully pre-dilated/pretreated

Exclusion criteria

  • Subject has clinical symptoms and/or electrocardiogram (ECG) changes consistent with acute ST elevation MI (STEMI)
  • Subject has cardiogenic shock, hemodynamic instability requiring inotropic or mechanical circulatory support, intractable ventricular arrhythmias, or ongoing intractable angina
  • Subject has received an organ transplant or is on a waiting list for an organ transplant
  • Subject is receiving or scheduled to receive chemotherapy within 30 days before or after the index procedure
  • Planned PCI (including staged procedures) or CABG after the index procedure
  • Subject previously treated at any time with intravascular brachytherapy
  • Subject has a known allergy to contrast (that cannot be adequately premedicated) and/or the trial stent system or protocol-required concomitant medications (e.g., platinum, platinum-chromium alloy, stainless steel, everolimus or structurally related compounds, polymer or individual components, all P2Y12 inhibitors (clopidogrel, ticlopidine, prasugrel, or ticagrelor), or aspirin)
  • Subject has one of the following (as assessed prior to the index procedure):
  • Other serious medical illness (e.g., cancer, congestive heart failure) with estimated life expectancy of less than 24 months
  • Current problems with substance abuse (e.g., alcohol, cocaine, heroin, etc.)
  • Planned procedure that may cause non-compliance with the protocol or confound data interpretation
  • Subject is receiving chronic (≥72 hours) anticoagulation therapy (i.e., heparin, coumadin) for indications other than acute coronary syndrome
  • Subject has a platelet count <100,000 cells/mm3 or >700,000 cells/mm3
  • Subject has a white blood cell (WBC) count < 3,000 cells/mm3
  • Subject has documented or suspected liver disease, including laboratory evidence of hepatitis
  • Subject is on dialysis or has baseline serum creatinine level >2.0 mg/dL (177µmol/L)
  • Subject has a history of bleeding diathesis or coagulopathy or will refuse blood transfusions
  • Subject has had a history of cerebrovascular accident (CVA) or transient ischemic attack (TIA) within the past 6 months
  • Subject has an active peptic ulcer or active gastrointestinal (GI) bleeding
  • Subject has severe symptomatic heart failure (i.e., New York Heart Association (NYHA) class IV)
  • Subject is participating in another investigational drug or device clinical trial that has not reached its primary endpoint
  • Subject intends to participate in another investigational drug or device clinical trial within 12 months after the index procedure
  • Subject with known intention to procreate within 12 months after the index procedure (women of child-bearing potential who are sexually active must agree to use a reliable method of contraception from the time of screening through 12 months after the index procedure)
  • Subject is a woman who is pregnant or nursing (a pregnancy test must be performed within 7 days prior to the index procedure in women of child-bearing potential)

Angiographic Exclusion Criteria (visual estimate)

Planned treatment of more than 3 lesions

  • Planned treatment of lesions in more than 2 major epicardial vessels
  • Planned treatment of a single lesion with more than 1 stent
  • Subject has 2 target lesions in the same vessel that are separated by less than 15 mm (by visual estimate)
  • Target lesion(s) is located in the left main
  • Target lesion(s) is located within 3 mm of the origin of the left anterior descending (LAD) coronary artery or left circumflex (LCx) coronary artery by visual estimate.
  • Target lesion(s) is located within a saphenous vein graft or an arterial graft
  • Target lesion(s) will be accessed via a saphenous vein graft or arterial graft
  • Target lesion(s) with a TIMI flow 0 (total occlusion) or TIMI flow 1 prior to guide wire crossing
  • Target lesion(s) treated during the index procedure that involves a complex bifurcation (e.g., bifurcation lesion requiring treatment with more than 1 stent)
  • Target lesion(s) is restenotic from a previous stent implantation or study stent would overlap with a previous stent
  • Subject has unprotected left main coronary artery disease (>50% diameter stenosis)
  • Subject has been treated with any type of PCI (i.e., balloon angioplasty, stent, cutting balloon atherectomy) within 24 hours prior to the index procedure
  • Thrombus, or possible thrombus, present in the target vessel (by visual estimate)
