Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate.

Inclusion Criteria :
- Male or female patient not at childbearing potential ≥18 year-old or legal age of majority.
- Female patient if she has undergone sterilization at least 3 months earlier or is postmenopausal.
- Post-menopausal status is defined by having no menses for 12 months without an alternative medical cause.
- In females not treated with hormonal replacement therapy (HRT), menopausal status is confirmed by a high follicle stimulating hormone (FSH) level greater than 40 IU/L.
- In females on HRT and whose menopausal status is in doubt (ie, in women aged less than 45 years), a highly effective contraception methods will be required. Contraception should be used during the whole study and for at least seven days corresponding to time needed to eliminate study treatment.
- Symptomatic stable angina pectoris (typical or atypical symptoms with at least once weekly episodes),
- Electrocardiogram (ECG) evidence of ischemia with ST-segment depression during a symptom limited exercise test or non-invasive evidence of ischemia [echo, single photon emission computed tomography (SPECT), magnetic resonance imaging (MRI), positron emission tomography (PET)] within previous 12 months.
- Patients with "normal" or "subnormal" (<50% stenosis) coronary arteries or intermediate stenosis (between 50 and 70%) should have fractional flow reserve (FFR) >0.80 on angiogram documented within the previous 12 months. In patients with stenting, a minimum diameter stenosis of <10% is required.
or Coronary computed tomography angiography (CCTA) without regional abnormal perfusion defects within 12 months in patients without previous PCI.
- Baseline global CFR (measured during the study) assessed by 13N-ammonia or 82rubidium PET scan <2.0.
- Esophageal dysmotility or esophagitis.
- Any use of long-acting nitrates and/or calcium channel blockers (CCBs) and/or phosphodiesterase type 5 (PDE5) inhibitors within one week prior to baseline PET scan or anticipated to be used during the study.
- Patients with acute coronary syndrome (ACS) [myocardial infarction (MI) and/or unstable angina] in previous 3 months.
- Unsuccessful or incomplete coronary revascularization with residual obstructive stenosis or coronary artery disease (CAD) progression in native vessels as documented on invasive coronary angiography (≥50% stenosis) within 12 months of enrollment.
- Patients with history of coronary artery bypass grafting (CABG).
- Percutaneous coronary intervention performed at the time of an ACS (MI or unstable angina).
- Recent elective PCI within the past 3 months.
- Contraindication to vasodilator stress PET scan.
- Regional local flow abnormal perfusion defects at baseline PET scan.
- Recent (≤3 months) major surgery (ie, valvular surgery, surgery for congenital heart disease), stroke, transient ischemic attack (TIA), sustained ventricular arrhythmia, clinically significant structural heart disease (moderate-severe valvular disease, hypertrophic cardiomyopathy, congenital heart disease, pulmonary hypertension).
- Patients with cardiac conduction abnormalities (second or third degree atrioventricular [AV] block, sick sinus syndrome, symptomatic bradycardia, sinus node disease).
- History of known carotid stenosis.
- Contraindication or known hypersensitivity to adenosine (or regadenoson).
- Contraindication to aminophylline.
- Ongoing dipyridamole treatment.
- Inability to discontinue treatment with methylxanthines treatment within 24 hours prior to PET scan.
- Patient unable to read, understand and fill a questionnaire without any help (eg, partially visually impaired or blind).
- Systolic Blood Pressure (SBP) <120 mmHg at baseline.
- Presence at baseline of symptomatic orthostatic hypotension (SBP decrease of 20 mmHg or more at Minute 3 and Minute 5 between seated and standing position), or asymptomatic orthostatic hypotension with a decrease in SBP equal or greater than 30 mmHg at Minute 3 and Minute 5 when changing from the seated to the standing position.
- Renal impairment [estimated glomerular filtration rate (eGFR) <50 milliliter (mL)/min/1.73m2 at screening and baseline].
- Drug-induced liver injury related criteria:
- Underlying hepatobiliary disease,
- ALT >3 times the upper limit of normal (ULN).
