Frequently asked questions about VTX3232

What is VTX3232?

VTX3232 is an investigational small molecule drug developed by Ventyx Biosciences, Inc. (ticker VTYX). It is being studied in Phase 2 clinical trials for idiopathic Parkinson disease and obesity. VTX3232 is also known as VTX3232 30 mg. It has not been approved by the FDA and remains in clinical development.

What is VTX3232 used for in Parkinson's disease and obesity?

VTX3232 is being evaluated as a potential treatment for idiopathic Parkinson disease and obesity. It is not approved for any indication. The clinical program includes a Phase 2a study in Parkinson's disease and a Phase 2a study in obesity, where it is tested alone or in combination with semaglutide.

What does VTX3232 target?

VTX3232 targets NLRP3, a component of the inflammasome. It acts as an NLRP3 inhibitor. By inhibiting NLRP3, the drug aims to reduce inflammation, which is thought to play a role in conditions such as Parkinson's disease and obesity. This mechanism is under investigation in Phase 2 trials.

Who makes VTX3232?

VTX3232 is developed by Ventyx Biosciences, Inc., a biopharmaceutical company with the ticker symbol VTYX. Ventyx is responsible for the clinical development of VTX3232, including the Phase 2a trials in Parkinson's disease and obesity.

What phase is VTX3232 in?

VTX3232 is in Phase 2 clinical development. It has completed a Phase 2a study in idiopathic Parkinson disease and a Phase 2a study in obesity. The drug is investigational and has not been approved by the FDA for any indication.

What clinical trials is VTX3232 in?

VTX3232 has been studied in two completed Phase 2a trials: NCT06771115, a placebo-controlled study of VTX3232 alone or with semaglutide in obesity, and NCT06556173, a Phase 2a study in idiopathic Parkinson disease. Both trials were conducted in the United States.
