Clinical Trial Summary

The purpose of the EVOLVE Trial is to assess the safety and performance of the everolimus-eluting Evolution stent for the treatment of a de novo atherosclerotic lesion of up to 28 mm in length in a native coronary artery 2.25 mm to 3.5 mm in diameter. The safety and performance of two different drug release rate formulations of the Evolution Stent will be compared to the commercially available PROMUS (TM) Element (TM) drug-eluting stent.

Recruitment information / eligibility

Eligibility

Inclusion Criteria:

• Patient must be at least 18 years of age

• 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 eligible for percutaneous coronary intervention (PCI)

• Patient has symptomatic coronary artery disease or documented silent ischemia

• Patient is an acceptable candidate for coronary artery bypass grafting (CABG)

• Patient has a left ventricular ejection fraction (LVEF) =30% as measured within 60 days prior to enrollment

• Patient is willing to comply with all protocol-required follow-up evaluations

Exclusion Criteria:

• Patient has clinical symptoms and/or electrocardiogram (ECG) changes consistent with acute MI

• Patient with unstable angina or recent MI (within 72 hours) must have CK/CK-MB or troponin documented prior to the procedure and are excluded if any of the following criteria are met at the time of the index procedure:

1. If CK MB >2× upper limit of normal (ULN), the patient is excluded regardless of the CK Total.

2. If CK Total >2× ULN, either CK-MB or troponin must be drawn and the patient is excluded if either CK-MB or troponin is abnormal.

3. If neither CK Total or CK MB is drawn but troponin is, the patient is excluded if:

• Troponin >1× ULN and the patient has at least one of the following:

• Patient has ischemic symptoms and ECG changes indicative of ongoing ischemia (e.g., >1 mm ST segment elevation or depression in consecutive leads or new left bundle branch block [LBBB])

• Development of pathological Q waves in the ECG; or;

• Imaging evidence of new loss of viable myocardium or new regional wall motion abnormality Note: Patients with stable angina must have CK/CK-MB or troponin drawn prior to the index procedure. However, the results for these patients do not need to be available prior to the index procedure and there are no exclusion criteria based on these studies.

• Patient has received an organ transplant or is on a waiting list for an organ transplant

• Patient is receiving or scheduled to receive chemotherapy within 30 days before or after the index procedure

• Patient is receiving oral or intravenous immunosuppressive therapy (e.g., inhaled steroids are not excluded ) or has known life-limiting immunosuppressive or autoimmune disease (e.g., human immunodeficiency virus, systemic lupus erythematosus, but not including diabetes mellitus)

• Patient is receiving chronic (=72 hours) anticoagulation therapy (e.g., heparin, coumadin) for indications other than acute coronary syndrome

• Patient has a platelet count <100,000 cells/mm3 or >700,000 cells/mm3

• Patient has a white blood cell (WBC) count <3,000 cells/mm3

• Patient has documented or suspected liver disease, including laboratory evidence of hepatitis

• Patient is on dialysis or has known renal insufficiency (e.g. serum creatinine level >2.0 mg/dL)

• Patient has active peptic ulcer disease, an active gastrointestinal (GI) bleed, other bleeding diathesis or coagulopathy, or will refuse transfusions

• Patient has had a cerebrovascular accident (CVA) or transient ischemic attack (TIA) within the past 6 months, or has any permanent neurologic defect that may cause non-compliance with the protocol

• Target vessel (including side branches) has been treated with any type of PCI (e.g., balloon angioplasty, stent, cutting balloon, atherectomy) within 12 months prior to the index procedure

• Target vessel has been treated within 10 mm proximal or distal to the target lesion (by visual estimate) with any type of PCI (e.g., balloon angioplasty, stent, cutting balloon, atherectomy) at any time prior to the index procedure

• Non-target vessel (including side branches) has been treated with any type of PCI (e.g., balloon angioplasty, stent, cutting balloon, atherectomy) within 24 hours prior to the index procedure Note: 1 lesion in a non-target vessel may be treated during the index procedure prior to the treatment of the target (study) lesion. The treatment of lesion(s) in non-target vessels more than 24 hours prior to the procedure does not preclude the treatment of an additional non-target lesion during the index procedure. For example, a patient could have an RCA lesion treated 7 days prior to the index procedure and then have a non-target lesion in the LCx and a target lesion in the LAD treated during the index procedure.

• Planned or actual target vessel treatment with an unapproved device, directional or rotational coronary atherectomy, laser, cutting balloon, or transluminal extraction catheter immediately prior to stent placement

• Planned PCI or CABG after the index procedure

• Patient previously treated at any time with coronary intravascular brachytherapy

• Patient has a known allergy to the trial stent system or protocol-required concomitant medications (e.g., stainless steel, platinum, chromium, nickel, tungsten, acrylic, fluoropolymers, everolimus, thienopyridines, aspirin, contrast) that cannot be adequately premedicated

• Patient has one of the following.

• Other serious medical illness (e.g., cancer, congestive heart failure) that may reduce life expectancy to 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

• Patient is participating in another investigational drug or device clinical trial that has not reached its primary endpoint

• Patient intends to participate in another investigational drug or device clinical trial within 12 months after the index procedure

• Patient 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.)

• Patient 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.)

• Patient has more than 1 target lesion and 1 non-target lesion that will be treated during the index procedure

• Patient has an additional clinically significant lesion(s) in the target vessel for which an intervention within 12 months after the index procedure may be required

• Non-target lesion to be treated during the index procedure meets any of the following criteria.

• Located within the target vessel

• Located within a bypass graft (venous or arterial)

• Left main location

• Chronic total occlusion
