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

EVOLVE II QCA: A Prospective, Multicenter Trial to Assess the SYNERGY Everolimus-Eluting Platinum Chromium Coronary Stent System (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)

• 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)

• 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)
