A Phase I Study in Healthy Volunteers to Evaluate the Safety of CardioPET™ in Detection of Coronary Artery Disease

Safety and dosimetry of CardioPET™ will be evaluated in normal healthy volunteers and CAD subjects both male and female between the ages of 50-85. Nine normal controls will undergo repeated whole body imaging for biodistribution and dosimetry estimation. Six other normal healthy subjects will undergo heart imaging only. Six CAD subjects will undergo heart imaging only.

CardioPET™ is a modified fatty acid (MFA) that closely resembles naturally-occurring free fatty acids (FFAs) in the human body.

Study Procedures:

Visit 1: Screening - Eligibility determination

Visit 2: Injection and PET Imaging

Visit 3: Follow-up Visit

Eligibility Criteria:
Inclusion Criteria:

Normal Healthy Volunteers:

* Subjects must be between the ages of 50 and 85 years of age.

Coronary Artery Disease (CAD) subjects:

* Subjects must provide written informed consent prior to any study related procedures;
* Subjects must be ≥ 50 and ≤ 85 years of age;
* Subject must have history of CAD documented by an exercise stress Myocardial Perfusion Imaging (MPI) study within 6 months documenting myocardial infarct without ischemia.

Exclusion Criteria:

Normal Healthy Volunteers:

* History of Diabetes Mellitus;
* Serum creatinine \> 2 mg/dL;
* All cancer and or chemotherapy patients;
* Body Mass Index (BMI) is over 35;
* Any exposure to any investigational drugs or medical device within four (4) weeks prior to imaging study;
