|Actual Study Completion Date :||November 19, 2018|
Patients with asymptomatic carotid atherosclerotic plaque with evidence of 50% or more carotid stenosis in one or more carotid arteries on carotid ultrasound within 2 years.
Patients will undergo carotid ultrasound and 99mTc-rhAnnexin V-128 SPECT/CT imaging.
Radiation: 99mTc-rhAnnexin V-128
Experimental: Healthy participants
Healthy participants with no significant carotid artery disease on carotid ultrasound.
Participants will undergo carotid ultrasound and 99mTc-rhAnnexin V-128 SPECT/CT imaging.
Radiation: 99mTc-rhAnnexin V-128
- Imaging feasibility (Proof of Concept step) [ Time Frame: Day 0 ]The feasibility of imaging apoptotic activity in carotid atherosclerotic plaques using 99mTc-rhAnnexin V-128 will be assessed by the data monitoring committee (visual image review and consensus). The frequency and severity of abnormal carotid scans will be determined in the patient and normal groups.
- Prevalence of abnormal 99mTc-rhAnnexin V-128 SPECT/CT imaging (Phase II step) [ Time Frame: Day 0 ]Prevalence of abnormal 99mTc-rhAnnexin V-128 SPECT/CT imaging.
- Background profile of control subjects [ Time Frame: Day 0 ]Descriptive statistics of 99mTc-rhAnnexin V-128 uptake in control subjects will be presented by areas of interest to assess the background uptake profile
- Echogenecity and echolucency correlations [ Time Frame: Baseline and Day 0 ]99mTc-rhAnnexin V-128 carotid uptake will be related to the ultrasound data of plaque echogenicity and echolucency.
- Aortic uptake correlation [ Time Frame: Day 0 ]99mTc-rhAnnexin V-128 uptake in carotids will be correlated to aortic uptake in all participants
- Adverse events [ Time Frame: From enrolment up to Day 30 ]Type and incidence of AEs, as well as severity and relatedness to the study medication will be described
- Laboratory tests [ Time Frame: At Baseline and Day 30 ]Pattern of participants with abnormal laboratory values will be analyzed based on clinical relevance
