E.2.1 | Main objective of the trial |
To demonstrate non-inferiority between the level of agreement in diagnosis (i.e. patient classification of normal, mild/moderate or severe ischemic disease based on the number of reversible perfusion segments) between sequential adenosine SPECT-MPI versus sequential SPECT-MPI with adenosine and apadenoson. |
|
E.2.2 | Secondary objectives of the trial |
Secondary Gatekeeper Objectives To demonstrate a statistically significant reduction with apadenoson treatment compared with adenosine treatment in the following treatment emergent AEs: • Incidence of dyspnea • VAS Symptom-Intensity Measure of dyspnea • Incidence of flushing • VAS Symptom-Intensity Measure of flushing • Incidence of chest pain • VAS Symptom-Intensity Measure of chest pain • Incidence of headache • VAS Symptom-Intensity Measure of headache • Incidence of nausea • VAS Symptom-Intensity Measure of nausea • Incidence of dizziness • VAS Symptom-Intensity Measure of dizziness • Incidence of abdominal discomfort • VAS Symptom-Intensity Measure of abdominal discomfort
Other Secondary Objectives (refer to protocol) |

E.3 | Principal inclusion criteria |
Subjects must meet all of the following inclusion criteria to be considered for inclusion in this study: • Referred for a clinically indicated rest /pharmacologic stress SPECT-MPI study • Male or female subject, 18 years of age or older • Must be able to provide written informed consent to participate before beginning any trial related activities • Must be able to communicate effectively with trial personnel • Subjects must have either high pretest probability of CAD based on age and gender and chest pain symptomatology assessed using the ACC/AHA guidelines for relative risk OR Have previously demonstrated known coronary artery disease based on medical history of prior myocardial infarction (MI), percutaneous coronary intervention (PCI), coronary artery bypass graft (CABG) or diagnostic angiogram demonstrating 50% or greater stenosis in one or more vessel, as well as reporting chest pain indicative of angina or anginal equivalents within the month prior to Pre-Study Evaluation (based on ACC criteria, e.g. dyspnea or extreme fatigue). • Can safely abstain from caffeine or methylxanthine containing foods for 24 hours, from dipyridamole for 24 hours, and from theophylline and methylxanthine containing medications for at least 72 hours (or 4 half-lives, whichever is longer) • Cardiovascular medication routine must remain stable from the time of signed informed consent through the Period 2 SPECT-MPI • If female, be (a) at least one year post menopausal or surgically sterile or (b) nonpregnant (as determined by a negative urine β-hCG pregnancy test within 24 hours before each period imaging session), and (c) non-lactating. Women of childbearing potential (WOCBP) must have been practicing a medically approved method of birth control since their last menstrual period and be willing to utilize adequate contraception and not become pregnant during the full course of the study. Adequate contraception is defined as continuous use of 1 of the following: o Norplant® (inserted at least 3 months prior to administration) o Medroxyprogesterone acetate injection (given >14 days prior to signed informed consent) o Oral contraception (stable use for 2 or more cycles prior to the time of signed informed consent and throughout the study) o Double-barrier method (e.g., condom or diaphragm plus spermicide, sponge, foam or jelly) o Intrauterine device (IUD, inserted >4 weeks prior to the time of signed informed consent) o Monogamous partner with a bilateral vasectomy (procedure performed >3 months prior to the time of signed informed consent) o Bilateral tubal ligation o Abstinence |
|
E.4 | Principal exclusion criteria |
Subjects meeting any of the following exclusion criteria will not be included in the study: • Ingestion of a caffeinated or methylxanthine food substance (e.g. chocolate, cocoa) within 24 hours before receiving apadenoson or adenosine • Treatment with dipyridamole within 24 hours, or theophylline, aminophylline, or pentoxifylline within 72 hours (or 4 half-lives, whichever is longer) prior to receiving apadenoson or adenosine • Exposure to any investigational drug or device within 30 days prior to the time of signed informed consent • Acute MI, new onset of ischemia or PCI within 30 days prior to SPECT-MPI at either Period 1 or Period 2; or CABG within 90 days prior to SPECT-MPI at either Period 1 or Period 2 • Any prior allergic response to aminophylline, adenosine, Tc99m Sestamibi, Thallium 201 or Tc99m Tetrofosmin or any of their components or other contraindication to pharmacologic stress testing with adenosine • Active severe asthma or severe chronic obstructive pulmonary disease (COPD) which, in the Investigator’s opinion, places the subject at risk for severe bronchoconstriction • History or evidence of clinically significant high grade AV block (including type 2 second or third degree block) or sinus node disease, such as sick sinus syndrome or symptomatic bradycardia, in the absence of a functioning permanently implanted pacemaker • Evidence of hemodynamically significant valvular disease or outflow tract obstruction • Uncontrolled severe hypertension or malignant ventricular arrhythmias • Current significant illness or disorder including significant laboratory abnormalities, ECG abnormalities, or other pathology that could potentiate any adverse pharmacological event associated with a vasodilating drug or any abnormality that, in the opinion of the Investigator, could put the subject at risk • Pretreatment hypotension (systolic BP < 90 mm Hg) or tachycardia (HR > 100 bpm) • Known history of cerebral vascular accident or suspected transient ischemic attack within 30 days prior to signed informed consent • Psychological or addictive disorder which may interfere with an ability to provide informed consent |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy endpoint will be the level of agreement of diagnosis (i.e. patient classification of normal, mild/moderate or severe ischemic disease based on the number of reversible perfusion segments) between sequential adenosine SPECT-MPI versus the level of agreement in diagnosis between an adenosine and an apadenoson SPECT-MPI. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Period 1 SPECT-MPI 7 +/-7 days following pre-study evaluation. Period 2 SPECT-MPI to be taken within 9 +/- 6 days after Period 1 SPECT-MPI. |

E.5.2 | Secondary end point(s) |
Secondary Gatekeeper Objective: To demonstrate a statistically significant reduction with apadenoson treatment compared with adenosine treatment in the incidence and intensity measure of dyspnea, flushing, chest-pain, headache, nausea, dizziness and, abdominal discomfort.
Other Secondary Objectives: • Assessment of adverse events (AEs), change in laboratory findings, physical examinations, vital signs, ECGs and number of discontinuations due to AEs •Incidence of atrioventricular (AV) block •Subject-rated Treatment experience • Agreement of Median Summed Stress Scores (SSS) • Interpretation of Wall Motion • Agreement of Extent of Ischemia • Comparison of Sensitivity and Specificity • Image Quality, Myocardial Region, Diagnostic Certainty and Overall Findings • Detection of Perfusion Defects According to Coronary Artery Territory
