|Condition or disease||Intervention/treatment||Phase|
|Coronary Artery Disease||Radiation: Radiolabeled (99Tc) EC-DG (ethylenedicysteine-deoxyglucose||Phase 2|
The study will assess the safety and tolerability of technetium-99m-labeled ethylenedicysteine-deoxyglucose (99mTc-EC-DG).
An outcome will be to develop an imaging protocol for a multicenter trial that will measure the specific imaging parameters required for determination of sensitivity and specificity of 99mTc-EC-DG in a cardiovascular single photon emission computed tomography (SPECT) study compared to an exercise/regadenoson 99mTc- Sestamibi (MIBI) study for detection of the presence and, when available, severity of coronary artery disease (CAD) as documented by coronary angiography when available.
This study will be a single-center, prospective, open-label study of up to 6 patients with positive findings from a MIBI (99mTc-sestamibi) exercise/regadenoson study within 30 days for evaluation of CAD. Patients who meet study eligibility criteria will undergo a 99mTc-EC-DG rest study and a 99mTc-EC-DG exercise/regadenoson study. When possible, patients enrolled will have clinical plans for a coronary angiography study to confirm presence and severity of CAD.
This study will enroll up to 6 patients with a reversible perfusion defect indicative of CAD on a MIBI exercise/regadenoson study. These patients will undergo a 99mTc-EC-DG rest study and an exercise/regadenoson study.

99mTc-EC-DG injection followed by SPECT imaging during a cardiac rest study (Visit 1) and an exercise/regadenoson study (Visit 2)
Radiation: Radiolabeled (99Tc) EC-DG (ethylenedicysteine-deoxyglucose
An injection of Technetium ethylenedicysteine-deoxyglucose (99mTc-EC-DG) to yield a target activity of 25 mCi (range of 10-25 mCi) with no more than 250 micrograms of EC-DG to be administered (there must be a minimum of 24 hours between Visit 1 and 2 administrations). Investigational Product to be given by IV push.
- Safety: The number of participants with Adverse Events [ Time Frame: From screening through 7 days after Investigational Product administration ]
