Ventyx Biosciences Reports Clinical Data for its NLRP3 Inhibitor Portfolio and Provides Pipeline Updates at Virtual Investor Event

VTX3232 was well-tolerated in the Phase 1 trial with robust target coverage achieved in both plasma and CSF; Ventyx is planning to initiate Phase 2a trials in Parkinson’s disease and obesity in H2 2024

Topline Phase 2 data for VTX2735 in CAPS patients establish clinical proof of concept; Ventyx is planning to evaluate VTX2735 in cardiovascular diseases

Early Phase 2 open-label extension data continue to support the clinical profile of VTX002 in ulcerative colitis; Ventyx is planning to seek a partner or other nondilutive financing for pivotal Phase 3 trial

Based on pipeline reprioritization and recent PIPE financing, Ventyx expects its current cash, cash equivalents and marketable securities to fund planned operations into at least H2 2026

SAN DIEGO, March 11, 2024 (GLOBE NEWSWIRE) -- 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, will provide clinical and pipeline updates today during its virtual investor event.

“We are excited to announce clinical updates from our novel NLRP3 inhibitor portfolio, including topline results from the Phase 1 trial of VTX3232 in healthy volunteers and topline results from the Phase 2 trial of VTX2735 in CAPS patients,” said Raju Mohan, Chief Executive Officer. “With these compelling clinical results and support from our recent PIPE financing, we are announcing a pipeline reprioritization, with internal resources to be focused on advancing our portfolio of potential best-in-class NLRP3 inhibitors in high value indications with substantial unmet medical need.”

Pipeline Updates

• VTX3232 (CNS-penetrant NLRP3 Inhibitor): We completed a Phase 1 single- and multiple-ascending dose trial of VTX3232 in adult healthy volunteers to assess the safety, pharmacokinetics and pharmacodynamics of VTX3232. Separate cohorts were included in this trial in which serial cerebrospinal fluid (CSF) sampling was conducted to assess drug exposure and target engagement in the CSF.
  
  VTX3232 was well-tolerated with no dose-limiting toxicities identified. All treatment-emergent adverse events were graded mild or moderate. VTX3232 exhibited a dose-dependent and dose-linear pharmacokinetic profile. Repeat doses of 3 mg QD maintained steady-state IL-1β IC₅₀ coverage in both plasma and CSF over 24 hours. Repeat doses of 40 mg QD exceeded steady-state IL-1β IC₉₀ coverage in both plasma and CSF over 24 hours. Robust, dose-dependent pharmacodynamic effects were observed in a whole blood ex vivo IL-1β stimulation assay. Additionally, reductions in inflammatory biomarkers were observed in plasma and CSF samples. 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.
