Frequently asked questions about venglustat

What is venglustat used for?

Venglustat is an investigational small molecule being developed for rare lysosomal storage disorders, specifically Fabry disease, Gaucher disease type 1, and Gaucher disease type 3. It is also being studied in adults with hepatic impairment to assess how the drug's pharmacokinetics are affected. Venglustat has received Fast Track and Orphan Drug designations from the FDA.

What does venglustat target?

Venglustat targets UDP-glucose ceramide glucosyltransferase, also known as UGCG. It acts as an inhibitor of this enzyme, which is involved in the synthesis of glucosylceramide, a key glycosphingolipid that accumulates in diseases such as Fabry and Gaucher disease. By inhibiting UGCG, venglustat aims to reduce the production of these harmful substrates.

Who is developing venglustat?

Venglustat is being developed by Sanofi, which trades under the ticker symbol SNY. Sanofi is conducting clinical trials of venglustat in multiple countries for indications including Fabry disease and Gaucher disease type 3.

What phase is venglustat in?

Venglustat is in Phase 3 clinical development. It is currently being evaluated in active Phase 3 trials for Fabry disease and Gaucher disease type 3, and a Phase 1 trial in hepatic impairment has been completed. Venglustat is investigational and has not been approved by the FDA.

What clinical trials is venglustat in?

Venglustat is being studied in several clinical trials. Key active Phase 3 trials include NCT05280548, which evaluates the effect of venglustat on left ventricular mass index in adults with Fabry disease, NCT05206773, which assesses its effect on neuropathic and abdominal pain in Fabry disease, and NCT05222906, which tests its efficacy and safety in Gaucher disease type 3. A completed Phase 1 trial, NCT05718258, investigated the impact of hepatic impairment on venglustat pharmacokinetics.

Is venglustat the same as GZ402671?

Yes, venglustat is also known by its development code GZ402671. Venglustat (GZ402671) is the same investigational drug developed by Sanofi. References to either name in scientific literature or clinical trial records refer to the same compound.
