Inclusion will be performed using an age-down staggered approach. Three age groups will be defined:~Group 1: patients aged 3 to 23 months (inclusive)~Group 2: patients aged 28 days to less than 3 months;~Group 3: patients aged from birth to 27 days (term newborns). The inclusions will start with the oldest patients (Group 1) and end with the youngest patients (Group 3). A total of 3 blood samples per patient will be taken post-injection for PK analysis.
This Phase II open-label, uncontrolled, multicenter trial is designed to investigate the pharmacokinetic (PK) profile of gadopiclenol in plasma, in pediatric patients aged up to 23 months inclusive (term neonates or preterm infants after the neonatal period), using a population PK approach.~Primary objective is to evaluate the PK profile of gadopiclenol in plasma following single intravenous injection of 0.05 mmol/kg body weight (BW) in pediatric population aged up to 23 months (inclusive) scheduled for a contrast-enhanced MRI examination of any body region including central nervous system (CNS).
