VTYX Ventyx Biosciences Inc

Ventyx Biosciences, Inc. (Nasdaq: VTYX) (“Ventyx”), a clinical-stage biopharmaceutical company focused on advancing novel oral therapies that address a broad range of inflammatory diseases with significant unmet medical need, today announced that the first patient has been dosed in a Phase 2a trial of VTX3232 in patients with early Parkinson’s disease.

“We are excited to initiate this trial of VTX3232 in patients with early Parkinson’s disease,” said Mark Forman, MD, PhD, Chief Medical Officer. “There is a compelling body of evidence from the literature suggesting a strong mechanistic rationale for targeting NLRP3-driven neuroinflammation in Parkinson’s disease and that microglial NLRP3 activation may play an important role in Parkinson’s disease pathogenesis and neurodegeneration. This trial will evaluate the effects of VTX3232 on disease- and target-relevant biomarkers and will also include exploratory PET neuroimaging to measure the impact of VTX3232 on microglial activation. These measures may provide early insights into the potential of VTX3232 to disrupt Parkinson’s disease pathology with NLRP3 inhibition in the CNS.”

The Phase 2a trial of VTX3232 in early Parkinson’s disease is expected to enroll approximately ten patients for a 28-day open-label treatment period. The trial’s primary endpoint is safety and tolerability. Other outcome measures include pharmacokinetics and relevant biomarkers in plasma and cerebrospinal fluid. We expect to report topline results from this trial in 2025.

About VTX3232

VTX3232 is an oral, selective, CNS-penetrant NLRP3 inhibitor with potential therapeutic utility for a range of neuroinflammatory and neurodegenerative conditions, including Parkinson’s disease, cardiometabolic disease, Alzheimer’s disease, and multiple sclerosis, among others. In the first quarter of this year, we announced results from a Phase 1 trial of VTX3232 in adult healthy volunteers where steady-state exposures achieved with once-daily doses of VTX3232 exceeded the interleukin-1β (IL-1β) IC90 in both plasma and cerebrospinal fluid over 24 hours. We believe these data support the potential for VTX3232 to emerge as a best-in-class CNS-penetrant NLRP3 inhibitor for the treatment of neuroinflammatory diseases.
