Ventyx Biosciences (Nasdaq: VTYX) has initiated dosing in a Phase 2a trial of VTX3232 for early Parkinson's disease. The trial aims to evaluate the drug's effects on disease- and target-relevant biomarkers, including exploratory PET neuroimaging to measure its impact on microglial activation. This study is based on evidence suggesting a strong mechanistic rationale for targeting NLRP3-driven neuroinflammation in Parkinson's disease.
The trial will enroll about ten patients for a 28-day open-label treatment period. Its primary endpoint is safety and tolerability, with additional measures including pharmacokinetics and relevant biomarkers in plasma and cerebrospinal fluid. Topline results are expected in 2025.
