About this study
Official title: Gadopiclenol Pharmacokinetics, Safety and Efficacy in Pediatric Patients < 2 Years of Age
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).
Read the detailed description
Three age groups are 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).
At study set-up, the inclusions started with the oldest patients in group 1 and using an age-down staggered approach.
The decision to start the inclusions in group 2 was taken by the Trial Safety Review Board based on safety assessment over one-day period after injection of the first 13 patients in group 1.
According to the protocol version 4 (amendments 2 \& 3), the age-down staggered approach was discontinued to allow the inclusions in Group 3 (patients aged from birth to 27 days), simultaneously to inclusions in group 1 and group 2.
A total of 3 blood samples per patient were taken post-injection for PK analysis.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
GadopiclenolDrug
Also called Elucirem
Patients will receive a single dose of gadopiclenol calculated according to their BW on the day of MRI examination. Gadopiclenol will be administered at a dose of 0.05 mmol/kg BW (0.1 mL/kg BW).

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Gadopiclenol in people with Central Nervous System Diseases and Pediatric Disorder, run by Guerbet at 11 sites in 3 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 28 Oct 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 11 sites in Poland, Hungary, United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 28 Oct 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Area Under the Curve (AUCinf) (time frame: A total of 3 blood samples per patient were collected post-injection of gadopiclenol for PK analysis, one within each window (10-60 minutes, 2-4 hours and 6-8 hours)). The study lists 10 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Oct 2025; AzTrials last refreshed its copy on 8 Nov 2026.
