General information about the trial
|
|||
Main objective of the trial |
To evaluate the pharmacokinetics (PK) of gadobutrol at the standard dose of 0.1 millimole per kilogram (mmol/kg) body weight (BW) in pediatric subjects from birth to less than 2 years of age (term newborn infants to toddlers 23 months of age inclusive).
|
||
Protection of trial subjects |
The number of pediatric subjects participating in this study and procedures performed such as blood sampling were minimized as far as feasible. A population-based PK approach was employed allowing sparse sampling for PK analysis.

Simulation is the use of the model to predict data other than observed data, in this case early Gadobutrol plasma concentration after intravenous injection.

Results per body regions were reported. Evaluation was done on pre-injection and combined (pre- and post-injection) images.

Estimated Glomerular Filtration Rate (eGFR) Prior to Gadobutrol Injection | ||||||||||||||||||
End point description |
The estimated glomerular filtration rate (eGFR) is used to assess the renal function in the pediatric population. eGFR was calculated based on the Schwartz formula with blood sampling for serum creatinine (Scr) not exceeding 14 days prior to gadobutrol injection. If Scr was measured with routine methods that had not been recalibrated to be traceable to isotope dilution mass spectrometry (IDMS), the eGFR was obtained from the original Schwartz formula: eGFR = k * height / Scr; where k is a proportionality constant (k = 0.45 in term newborn infants < 1 year of age, and k = 0.55 in children up to 13 years of age). If Scr was measured by an enzymatic creatinine method that had been calibrated to be traceable to IDMS, the updated Schwartz formula was used to obtain the eGFR: eGFR = 0.413 * height / Scr. eGFR was reported in the following age groups: < 1 month, 1 to < 2 months, 2 to < 6 months, 6 to < 12 months, and 12 to < 24 months.

Number of Subjects With Drug Related Serious and Non-Serious Adverse Events | ||||||||||
End point description |
An Adverse Event (AE) was any untoward medical occurrence attributed to study drug in a subject who received study drug. A Serious Adverse Event (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.
Drug-related adverse events are AEs as determined by the Investigator. The relatedness between adverse events and the administration of treatment was determined by the Investigator based on his/her clinical decision based on all available information. The assessment of the causal relationship to study drug was based on the question whether there was a “reasonable causal relationship” to the study treatment in question.
