E.2.1 | Main objective of the trial |
Primary Objective: Determine the sensitivity and specificity of the 15O-H2O positron emission tomography (PET) myocardial perfusion imaging (MPI) to detect coronary artery disease (CAD) using the truth-standard of invasive coronary angiogram (ICA) with fractional flow reserve (FFR) or instantaneous wave-Free Ration (iFR) coronary computed tomography angiogram (CCTA).

Secondary Objectives: 1) Determine the sensitivity and specificity of 15O-H2O PET MPI in subjects of special clinical interest (female, BMI≥30, diabetics, multivessel disease); 2) Evaluation of the safety of 15O-H2O during PET MPI.
|
Bestemme følsomheden og specificiteten af 150-H20 PET MPI hos personer af særlige klinisk interesse (kvinder, BMI ≥30, diabetikere, multikar-sygdom); 2) Evaluering af sikkerheden ved 150-H20 under PET MPI.

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Male and female subjects ≥18 years; 2. Informed consent form (ICF) read, signed, and dated prior to any study procedures being performed; 3. Subjects who fall into any one of the following categories: a) Have been referred for an ICA directly after non-invasive testing (e.g., SPECT or PET MPI, stress echo, CCTA, ETT). b) Had an ICA with no intervention. However, if any stenosis >40% but ≤70% was observed, an FFR assessment was performed. c) Had a CCTA with normal coronaries or minimal CAD (Less than < 20% stenosis).
The PET 15O-H2O study and ICA or CCTA testing need to be completed within a 30-day window, with time 0 defined as the date of the first of these three tests, or the screening visit for Pathway 1.
4. Women of Child Bearing Potential (WOCBP) must be non-pregnant, and non-lactating. For women of childbearing potential, the results of a urine human chorionic gonadotropin (HCG) pregnancy test (with the result known on the day of drug administration) must be negative; these patients must be practicing appropriate birth control from time of the screening until end of the follow up period. For women who are either surgically sterile (have a documented bilateral tubal ligation or oophorectomy and/or hysterectomy) or are post-menopausal (cessation of menses for more than 1 year); enrollment in the study without a pregnancy test at screening is allowed. 5. Male will need to use contraceptive methods until end of the follow-up period. 6. Patients are able to comply with all study procedures as described in the protocol.

1. Mandlige og kvindelige forsøgspersoner ≥18 år; 2. Deltagerinformation og samtykkeerklæringen skal læses, underskrives og dateres, før der udføres forsøgsprocedurer; 3. Personer, der falder ind under en af følgende kategorier (se ovenfor): a) Henvist til invasiv KAG direkte eller efter non-invasiv undersøgelse (ex. SPECT, 82Rb PET, stress ekkokarduiografi, ergometertest) b) Har fået foretaget en invasiv KAG uden intervention (PCI). Såfremt stenoser blev vurderet til at være mellem 40 og 70 % skal der foreligge FFR- måling af disse. c) Har fået foretaget en CT med kontrast med normale forhold eller minimale forandringer (mindre end <20 % stensose).
PET 15O-H2O-forsøget og KAG eller CT-undersøgelsen skal gennemføres inden for et 30-dages vindue, hvor tidspunkt 0 er defineret som datoen for den første af disse tre tests, eller screening besøg for Pathway 1.
4. Kvinder i fødedygtig alder må ikke være gravide og må ikke amme. For kvinder i fødedygtig alder skal resultaterne af en graviditetstest med humant choriongonadotropin (HCG) i urinen være negativ (med resultatet kendt på dagen for lægemiddeladministrationen); disse patienter skal praktisere passende prævention fra tidspunktet for screeningsbesøget til afsluttet follow-up. For kvinder, der enten er kirurgisk sterile (har en dokumenteret bilateral tuballigation eller ooporektomi og/eller hysterektomi) eller er postmenopausale (ophør af menstruation i mere end 1 år), er det tilladt at deltage i forsøget uden graviditetstest ved screening. 5. Mænd skal bruge prævention indtil afsluttet follow-up. 6. Patienterne er i stand til at overholde alle forsøgsprocedurer som beskrevet i protokollen.
