PET Imaging of Natriuretic Peptide Receptor C (NPR-C) in Carotid Atherosclerosis

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02417688
Recruitment Status : Completed

Brief Summary:
To demonstrate feasibility of imaging Cu[64]-25%-CANF-Comb uptake in the atherosclerosis of the carotid artery of patients for whom carotid artery endarterectomy surgery is planned in comparison to the carotid artery for which intervention is not planned.

Condition or disease Intervention/treatment Phase
Carotid Atherosclerosis Device: Cu[64]-25%-CANF-Comb PET-MR Phase 1

Detailed Description:
This study is a single center, open-label baseline controlled imaging study designed to demonstrate feasibility of PET imaging of radiopharmaceutical nanoparticle Cu[64]-25%CANF-Comb uptake by PET-MR. Patients will undergo Cu[64]-25%CANF-Comb PET-MR imaging of both carotid arteries. Both carotid arteries will be imaged at the same time. We hope to demonstrate differences in PET SUV (Standardized Uptake Value) in the significantly atherosclerotic artery in patients who will be going to carotid endarterectomy surgery in comparison to the PET SUV in the artery that is not significantly diseased (ie; the artery that will not undergo surgery) . We also will determine whether PET SUV of the Cu[64]-25%CANF-Comb by the plaque correlates to the American Heart Association classifications of atherosclerosis and tissue presence of NPR-C in the ex vivo carotid endarterectomy specimen post surgery as measured by RT-PCR.

Arm Intervention/treatment
Experimental: Cu[64]-25%-CANF-Comb PET-MR
Single IV injection of 4-8 mCi of Cu[64]-25%-CANF-Comb with a mass no more than 100 μgrams followed by PET-MR Imaging
Device: Cu[64]-25%-CANF-Comb PET-MR

Primary Outcome Measures :
  1. PET SUV (Standardized Uptake Value) [ Time Frame: 22-26 hours ]
    Difference in SUV between the carotid with atherosclerosis (carotid artery to be undergo surgery) and the carotid artery without significant disease (artery for which surgery is not planned).
