CAD Participants
Healthy Participants
Participants with asymptomatic or previously symptomatic with TIA only carotid atherosclerotic plaque with evidence of 50% or more carotid stenosis in one or more carotid arteries on carotid ultrasound within 2 years, received a single intravenous bolus of 350 MBq ± 10 % of 99mTc-rhAnnexin V-128 via an intraveneous (IV) catheter in an antecubital vein, followed by a saline flush on screening (Day 0).
Healthy participants with no significant carotid artery disease on carotid ultrasound, received a single intravenous bolus of 350 MBq ± 10 % of 99mTc-rhAnnexin V-128 via an IV catheter in an antecubital vein, followed by a saline flush on screening (Day 0).
