Treatment Arms

ArmTypeDescription
Cohort 1: Eliglustat monotherapyEXPERIMENTALEliglustat for at least two years. Cohort 1 patients that experience significant clinical decline will receive rescue treatment. Rescue Treatment Step 1: Switch from eliglustat to imiglucerase monotherapy. Rescue Treatment Step 2: Patients who after 6 months of rescue therapy with imiglucerase monotherapy do not show improvement in the parameter(s) that led to the switch from eliglustat to imiglucerase, will then receive combination therapy with eliglustat + imiglucerase.
Cohort 2: Eliglustat plus imigluceraseEXPERIMENTALEliglustat plus imiglucerase for three years, at the dose of enzyme replacement therapy received before enrollment. After Week 52, Cohort 2 patients will switch to eliglustat monotherapy for the remainder of the study if the desired clinical response has been achieved.

Frequently asked questions about Eliglustat GZ385660

What is Eliglustat GZ385660 used for?

Eliglustat GZ385660 is being developed for the treatment of Gaucher's disease type I, a rare inherited lysosomal storage disorder. It is a small molecule under investigation for this rare disease indication. The drug has been studied in a Phase 3 trial that also included patients with Gaucher's disease type III.

What does Eliglustat GZ385660 target?

Eliglustat GZ385660 targets UGCG, also known as glucosylceramide synthase. It acts as an inhibitor of this enzyme. By inhibiting UGCG, the drug aims to reduce the production of glucosylceramide, the substance that accumulates in Gaucher's disease.

Who is developing Eliglustat GZ385660?

Eliglustat GZ385660 is being developed by Sanofi, a global pharmaceutical company. Sanofi trades on the New York Stock Exchange under the ticker symbol SNY. The company is responsible for the clinical development of this investigational therapy for Gaucher's disease type I.

What phase is Eliglustat GZ385660 in?

Eliglustat GZ385660 is in Phase 3 clinical development. It is an investigational drug and has not been approved by the FDA for any indication. The Phase 3 trial for this drug has been completed, and further regulatory steps would be required before any potential approval.

What clinical trials is Eliglustat GZ385660 in?

Eliglustat GZ385660 has been evaluated in one completed Phase 3 clinical trial, NCT03485677. The trial enrolled 57 pediatric patients with Gaucher disease type 1 and type 3 across multiple countries. It was a controlled study assessing safety and efficacy, with or without imiglucerase, and included biomarker-selected patients.
