E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
This is a paediatric dosimetry study of Rubidium (82Rb) chloride injection. The main objectives of the trial are - To compare paediatric and adult time-integrated activity coefficients (ã) of 82Rb chloride - To confirm that estimates of paediatric radiation doses based on adult ã are comparable to estimates based on paediatric ã - To estimate paediatric dosimetry data of rubidium 82Rb chloride - To determine the safety and tolerability of 82Rb chloride administered intravenously |

|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
a. Male or female aged from 1 month to less than 18 years of age at the time of signing consent/assent b. Patients in whom myocardial perfusion imaging with 82Rb chloride PET scan is clinically indicated (patients that may already have had 82Rb PET scan imaging in the past, for any reason, can be included in the study) c. Fully informed and signed consent from parent(s)/legal representative for all age groups prior to any study-related procedures. Patient consent will be obtained as of the age of 14, in accordance with Swiss regulations d. An understanding, ability, and willingness, or respectively in children unable to speak, absence of continuous adverse behavior, to fully comply with study procedures and restrictions, including if warranted, sedation or anesthesia e. Females of child-bearing potential must have a negative urine pregnancy test at day of imaging procedure |
|
E.4 | Principal exclusion criteria |
a. History of organ-removal surgery (e.g., nephrectomy, cholecystectomy, or splenectomy) b. Presence of any concurrent disease, condition or treatment, which, in the investigator’s opinion would interfere with study participation or confound the results of the study, e.g.: renal failure, severe uncontrolled asthma. c. Known hypersensitivity to 82Rb chloride or its excipients d. Contra-indication to sedation/anaesthesia e. Insufficient venous access f. Contra-indication to pharmacological stress (adenosine): decompensated asthma, STEMI <48h, symptomatic bradycardia, second- or third-degree heart block or Sick sinus syndrome (without a pacemaker), hypersensitivity to adenosine g. Unable to undergo PET scan assessment, e.g.: claustrophobia h. Within 30 days prior to screening visit, use of experimental or unregistered drugs that may affect the study outcomes i. Pregnancy or breast feeding j. Contra-indication to aminophylline: Known hypersensitivity to aminophylline, theophylline, ethylenediamine or one of its excipients, acute coronary thrombosis, acute tachycardia |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary outcome will evaluate organ radiation absorbed doses and effective dose. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
After all patients had the PET/CT scans with rubidium (82Rb) chloride |
|
E.5.2 | Secondary end point(s) |
- Time-integrated activity coefficients (ã) calculated for all organs imaged - Paediatric (ã) compared to adult values - Organ radiation doses for all paediatric phantoms calculated by OLINDA/EXM V1.1 for each patient’s data set - Mean radiation dose for the paediatric phantoms based on paediatric input data and compared to those previously calculated based on adult data - Effective dose coefficients (e) and effective dose (ED) calculated using both ICRP 60 (1) and ICRP 103 (2) tissue weightings and definition - Safety and tolerability of 82Rb chloride administered intravenously |
