What this Trial Is About

This a Phase 3, prospective, open-label, multicenter study of \[15-O\]-H2O injection for PET imaging of subjects with suspected CAD. Approximately 182 evaluable participants with suspected CAD referred for testing will be included in the study at approximately 10 study sites in the United States and Europe. Approximately 215 participants will be enrolled to account for an estimated 15% drop-out rate. Screening assessments will occur prior to enrollment to confirm eligibility. All participants will receive two doses of \[15-O\]-H2O as part of a single PET imaging session (one dose at rest and one during pharmacological stress with adenosine). A safety follow-up phone call will occur 24 ± 8 hrs after completion of the \[15-O\]-H2O scan.

Eligibility Criteria

Eligible

You may qualify if you...

  • Participants aged 18 years or older
  • Participants who have given signed informed consent
  • Participants referred for invasive coronary angiography directly or after non-invasive testing (e.g., SPECT, PET MPI, stress echo, CCTA, or exercise treadmill test)
  • Participants who had invasive coronary angiography with no intervention but had a fractional flow reserve or instantaneous wave-free ratio assessment if stenosis between 40% and 70% was observed
  • Participants who had a computed tomography coronary angiogram with normal or minimal coronary artery disease (no stenosis over 25%)
  • All coronary testing (SPECT, PET 15O-H2O, and invasive or CT angiography) completed within a 30-day window
  • Women of childbearing potential must be non-pregnant, non-lactating, have a negative urine pregnancy test on the day of drug administration, and use appropriate birth control until the end of follow-up
  • Women surgically sterile or post-menopausal for over 1 year may enroll without a pregnancy test
  • Male participants must use contraception until the end of follow-up
  • Participants able to comply with all study procedures
Not Eligible

You will not qualify if you...

  • Participants unable to undergo all or part of the imaging procedures
  • Participants with a history of cardiac disease including myocardial infarction, previous coronary revascularization, chronic ischemic cardiomyopathy, primary myocardial disease like cardiac amyloidosis or hypertrophic cardiomyopathy, left ventricular dysfunction, or moderate to severe aortic or mitral valve stenosis or regurgitation
  • Participants for whom adenosine stress testing is contraindicated, including those with severe COPD, chronic asthma, or second- or third-degree atrioventricular block without a pacemaker
  • Participants with claustrophobia severe enough to limit imaging participation, unless controlled with drugs or psychological support
  • Participants taking sildenafil, dipyridamole, or PDE5 inhibitors who cannot stop these drugs 24 hours before study drug administration
  • Participants with significant co-morbidities preventing protocol completion
  • Participants who have participated in another investigational drug study within 30 days prior or during this trial
  • Participants who have previously participated in this study
  • Participants scheduled for or planning interventional cardiac procedures between enrollment and the coronary angiography or PET imaging
