About this study
Official title: Open Label, Two Cohort (With and Without Imiglucerase), Multicenter Study to Evaluate Pharmacokinetics, Safety, and Efficacy of Eliglustat in Pediatric Patients With Gaucher Disease Type 1 and Type 3
Primary Objective:
Evaluated the safety and pharmacokinetics of eliglustat in pediatric participants (≥2 to <18 years old).
Secondary Objective:
Evaluated the efficacy of eliglustat and quality of life in pediatric participants (≥2 to <18 years old).
Read the detailed description
The study included a screening period of up to 60 days (Day -60 to -1), a primary analysis treatment period (Day 1 to Week 52), a long-term treatment period (Week 53 to Week 104), and an extension period continuing up to Week 364 (for patients who continue to demonstrate the clinical benefit from eliglustat monotherapy at Week 104). After study completion, participants were encouraged to enroll in the International Collaborative Gaucher Group (ICGG) Gaucher Registry.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Eliglustat GZ385660 and Imiglucerase GZ437843 in people with Gaucher's Disease Type I and Gaucher's Disease Type III, run by Sanofi at 21 sites in 10 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 15 inclusion and 9 exclusion criteria. 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 16 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 21 sites in Russia, Canada, Spain, Turkey (Türkiye), Japan and 5 more countries. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Assessment of pharmacokinetic (PK) parameter of eliglustat: Cmax (time frame: Weeks 2, 13, 26 and 52). The study lists 3 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 16 Jun 2026.
