Brief Summary

The CANARY (Coronary Assessment by Near-infrared of Atherosclerotic Rupture-prone Yellow) Study is a pivotal trial to evaluate criteria for defining a Lipid Core Plaque (LCP) that is at high risk of rupturing during standard of care therapy and causing intra-procedural complications. If plaques that require treatment are at higher than normal risk of causing intra-procedural complications, some life threatening, the treating physician is better informed and may opt to take precautionary measures to mitigate the risk or result of a complication. The CANARY Study is also designed to evaluate the feasibility of using a distal embolization protection device (EPD) as a means to prevent heart attacks triggered by the embolization of plaque during standard care therapy. It is thought that the EPD will prevent plaque from going downstream during treatment and obstructing other heart vessels. These obstructions could cause heart attacks by preventing blood from reaching heart muscle tissue.

Outcome Measures

Primary Outcomes (1)

  • Evidence of Peri-procedural Myocardial Infarction as the result of standard care stenting procedure.

    The occurrence of a peri-procedural MI in the context of the CANARY trial will be defined as an elevation of troponin I (cTnI), or troponin T (cTnT) above three times the upper limit of normal (\>3xULN).

    <24 hours after percutaneous coronary intervention

Secondary Outcomes (4)

  • Evidence of Peri-procedural Myocardial Infarction as the result of standard

    <24 hours after percutaneous coronary intervention

  • Frequency of Intraprocedural complications related to the treatment of the Target Plaque.

    Catheterization Start Time to Completion Time.

  • Composite MACE

    from discharge from initial hospital stay to 30 (+/-7days) following the procedure

  • Composite MACE

    365 days (+/- 30days) from initial procedure

Study Arms (3)

(+)HR-LCP and EPD

EXPERIMENTAL

These subjects will meet all angiographic criteria.The target plaque will contain a LipiScan IVUS signal that meets the Higher Risk Lipid Core Plaque (HR-LCP) definition contained in the protocol. 27 Subjects who meet this criteria will be randomized to standard pre-dilation and stent implantation with an embolic protection device (EPD)in place prior to any angioplasty.

Device: Embolic Protection Device (EPD)Device: Intracoronary Spectroscopy and Ultrasonic EvaluationDevice: Angioplasty and Stent Implant

(+)HR-LCP and No EPD (standard of care)

PLACEBO COMPARATOR

These subjects will meet all angiographic criteria.The target plaque will contain a LipiScan IVUS signal that meets the Higher Risk Lipid Core Plaque (HR-LCP) definition contained in the protocol. 27 Subjects who meet this criteria will be randomized to standard pre-dilation and stent implantation without an embolic protection device (EPD)in place prior to any angioplasty.

Device: Intracoronary Spectroscopy and Ultrasonic EvaluationDevice: Angioplasty and Stent Implant

(-)HR-LCP and No EPD (standard of care)

PLACEBO COMPARATOR

These subjects will meet all angiographic criteria.The target plaque will NOT contain a LipiScan IVUS signal that meets the Higher Risk Lipid Core Plaque (HR-LCP) definition contained in the protocol. 54 Subjects who meet this criteria will be assigned (not randomized) to standard pre-dilation and stent implantation without an embolic protection device (EPD)in place prior to any angioplasty.

Device: Intracoronary Spectroscopy and Ultrasonic EvaluationDevice: Angioplasty and Stent Implant

Interventions

The embolic protection device consists of a protection wire, a delivery sheath, a retrieval sheath and various accessories (wire torque device, introducer, dilator tool). The wire of the EPD is used as a standard 0.014" steerable guide wire. The filter is designed for embolic debris capture while maintaining continuous blood flow. At the completion of the procedure, the filter and its contents are removed using the retrieval sheath and then removed from the patient.

Also known as: Filterwire
(+)HR-LCP and EPD

This intervention requires a near infrared imaging catheter equipped with an intravascular ultrasonic transducer be used to evaluate the coronary artery wall prior to treatment and after treatment. This system detects the lipid containing plaques that may be the source of embolic debris released during standard angioplasty and stent placement.

Also known as: LipiScan IVUS Coronary Imaging System, LipiScan IVUS, LipiScan, Chemogram
(+)HR-LCP and EPD(+)HR-LCP and No EPD (standard of care)(-)HR-LCP and No EPD (standard of care)

The target plaque will be treated with a pre-dilation with a standard angioplasty balloon sized to within 0.5mm of the diameter of the reference vessel diameter. The physician will then implant a coronary artery stent that is appropriately sized for the reference vessel diameter.
