Experimental: Combo - The Combo Stent is composed of the OrbusNeich R stentâ„¢, with an abluminal coating of a bioabsorbable polymer matrix formulated with sirolimus for sustained release, and an anti-CD34 antibody cell capture coating on the luminal surface.

Active Comparator: Taxus® Liberté® Stent - Commercially available product

Treatment: Devices: coronary stenting
Balloon dilatation of obstructive coronary artery disease with deployment of a metallic stent to scaffold the dilated lesion; stent incorporating sustained release of anti-proliferative agent to control neointimal proliferation and reocclusion; test device incorporates affinity surface for circulating EPCs

Key inclusion criteria
General Inclusion Criteria

- The patient must be =18 and = 80 years of age;

- Symptomatic ischemic heart disease (CCS class 1-4, Braunwald Class IB, IC, IIB, IIC,
IIIB, IIIC, and/or objective evidence of myocardial ischemia);

- Acceptable candidate for CABG;

- The Patient is willing to comply with specified follow-up evaluations;

- The Patient or legally authorized representative has been informed of the nature of
the study, agrees to its provisions and has been provided written informed consent,
approved by the appropriate Medical Ethics Committee (MEC), Institutional Review Board
(IRB), or Human Research Ethics Committee (HREC).


- Single de novo or non-stented restenotic lesion in the target vessel;

- Patients with two-vessel coronary disease, may have undergone successful treatment
(<20% diameter stenosis by visual estimate) of the non-target vessel with approved
devices up to and including the index procedure but must be prior to the index target
vessel treatment. Any non-target vessel or lesion intended to be treated during the
index procedure, cannot be an unprotected left main, ostial lesion, chronic total
occlusion (CTO), heavily calcified, bifurcation, vein grafts, have angiographic
evidence of thrombus, be anything requiring atherectomy, thrombectomy, or
pre-treatment with anything other than balloon angioplasty;

- Target lesion located in a native coronary artery;

- Target lesion (maximum length is 20 mm by visual estimate) covered by a single stent
maximum 23 mm length for Combo Stent, and 24 mm in length for TAXUS® Liberté® (stent
coverage including at least 3 mm of healthy vessel is recommended). The lesion length
should be measured after pre-dilation procedure;

- Reference vessel diameter must be =2.5 to = 3.5 mm by visual estimate. The vessel
diameter should be measured after pre-dilation procedure and after intra-coronary
nitroglycerin if spasm is suspected;

- Target lesion =50% and <100% stenosed by visual estimate.
Minimum age
18 Years
Maximum age
80 Years
Both males and females
Can healthy volunteers participate?

standard test;

to within normal limits at the time of procedure;

- The patient is currently experiencing clinical symptoms consistent with new onset AMI,
such as nitrate unresponsive prolonged chest pain;

- Patient has a history of bleeding diathesis or coagulopathy or patients in whom
anti-platelet and/or anticoagulant therapy is contraindicated;

- Patient requires low molecular weight heparin (LMWH) treatment post-procedure or has
received a dose of LMWH =8 hours prior to index procedure;

- Patient has received any organ transplant or is on a waiting list for any organ

- Patient has other medical illness (e.g., cancer, known malignancy, or congestive heart
failure) or known history of substance abuse (alcohol, cocaine, heroin etc.) that may
cause non-compliance with the protocol, confound the data interpretation or is
associated with a limited life expectancy (i.e., less than 1 year);

- Patient has a known hypersensitivity or contraindication to aspirin,
heparin/bivalirudin, clopidogrel/ticlopidine, prasugrel, stainless steel alloy,
sirolimus, paclitaxel and/or contrast sensitivity that cannot be adequately

- Patient has previously received murine therapeutic antibodies and exhibited
sensitization through the production of Human Anti-Murine Antibodies (HAMA);

- Patient presents with cardiogenic shock;

- Patient has current unstable cardiac arrhythmias that create hemodynamic instability;

- Patient has extensive peripheral vascular disease that precludes safe 6 French sheath

- Any significant medical condition which in the Investigator's opinion may interfere
with the patient's optimal participation in the study;

- Currently participating in another investigational drug or device study or patient in
inclusion in another investigational drug or device study during follow-up;


- Unprotected left main coronary artery disease with =50% stenosis;

- Ostial target lesion(s);

- Totally occluded target vessel (TIMI flow 0);

- Calcified target lesion(s) which cannot be successfully predilated;

- Target lesion has excessive tortuosity unsuitable for stent delivery and deployment;

- Angiographic evidence of thrombus in the target lesion(s);

- Target lesion involving bifurcation with a side branch =2.0 mm in diameter (either
stenosis of both main vessel and major side branch or stenosis of just major side
branch) that would require intervention of diseased side branch;

- A significant (>50%) stenosis proximal or distal to the target lesion that cannot be
covered by same single stent;

- Diffuse distal disease to target lesion with impaired runoff;

- Left ventricular ejection fraction (LVEF) =30% (LVEF must be obtained within 6 months
prior to the index procedure);

- Pre-treatment with devices other than balloon angioplasty;

- Prior stent within 10 mm of target lesion;

- Intervention (PCI or bypass) of another lesion performed within 6 months before or
planned within 30 days following the index procedure.
