SAN DIEGO, Jan. 14, 2025 (GLOBE NEWSWIRE) -- Ventyx Biosciences, Inc. (Nasdaq: VTYX) (“Ventyx”, “Company”), a clinical-stage biopharmaceutical company focused on developing innovative oral therapies for patients with autoimmune, inflammatory, and neurodegenerative diseases, today highlighted its 2025 pipeline strategy and provided clinical updates on its NLRP3 inhibitor portfolio, including VTX2735 and VTX3232.

“We believe that 2025 will be a transformative year for Ventyx with important clinical data readouts from our NLRP3 portfolio, including VTX2735, our peripherally restricted NLRP3 inhibitor and VTX3232, our CNS-penetrant NLRP3 inhibitor,” said Raju Mohan, PhD, President and Chief Executive Officer. “With three trials expected to be underway by the end of January, we plan to report topline results from the Phase 2 biomarker trial of VTX3232 in patients with early Parkinson’s disease in the first half of 2025, followed by results from the Phase 2 trial of VTX2735 in patients with recurrent pericarditis and the Phase 2 trial of VTX3232 in participants with obesity and cardiometabolic risk factors during the second half of 2025. With these readouts, we aim to establish Ventyx as a leader in the field of the NLRP3 inflammasome, with the potential to explore opportunities in multiple systemic and neurological diseases, including those in which IL-1 antagonism has already been validated as a therapeutic approach.”

Pipeline Updates and Anticipated Milestones

NLRP3 Inhibitor Portfolio: Ventyx is advancing a portfolio of potential best-in-class oral NLRP3 inhibitors for systemic inflammatory conditions and neurodegenerative diseases, including VTX2735, a peripherally restricted NLRP3 inhibitor, and VTX3232, a CNS-penetrant NLRP3 inhibitor.

• VTX2735 in Recurrent Pericarditis: A single dose, open-label Phase 2 trial of VTX2735 in participants with recurrent pericarditis is expected to initiate in January. The trial will enroll approximately 30 participants for a 6-week primary treatment period, followed by a 7-week extension period. Key endpoints include safety, change in the NRS pain score, and change in high sensitivity C-reactive protein (hsCRP). Topline results are expected in the second half of 2025.
  
  Recurrent pericarditis is considered to be an autoinflammatory condition caused by over-activity of the innate-immune system. In particular, the disease pathophysiology is associated with aberrant activation of the NLRP3 inflammasome and IL-1, the initial cytokine of the innate immune system. Recently, concentrations of NLRP3 have been shown to be elevated in pericardial samples from patients with recurrent pericarditis compared to healthy controls. Patients refractory to non-steroidal anti-inflammatory drugs (NSAIDs) and colchicine are commonly treated with injectable IL-1 therapies, though substantial unmet medical need remains. We believe that, by treating and preventing disease recurrence, VTX2735 has the potential to offer a safe, effective, and convenient oral therapy for patients suffering from recurrent pericarditis.

• VTX3232 in Cardiometabolic Diseases: Dosing has initiated in a randomized, placebo-controlled Phase 2 trial of VTX3232 in participants with obesity and cardiometabolic risk factors. The trial is expected to enroll approximately 160 subjects randomized to one of four groups for a 12-week primary treatment period: monotherapy placebo, monotherapy VTX3232, combination semaglutide + placebo, or combination semaglutide + VTX3232. Key endpoints include safety and change in hsCRP. The trial also includes a panel of exploratory endpoints, including biomarkers of inflammation and cardiometabolic disease, as well as imaging to assess body composition and liver fat. Topline results are expected in the second half of 2025.
  
  Activation of the NLRP3 inflammasome, and resulting chronic inflammation, has been linked to a range of cardiometabolic diseases including atherosclerosis, insulin resistance, and obesity. The Phase 2 trial of VTX3232 in participants with obesity and cardiometabolic risk factors is designed as a signal-finding trial to identify the effects of NLRP3 inhibition on a broad panel of inflammatory and metabolic biomarkers, including IL-6 and hsCRP. Data from the Phase 2 trial are expected to inform future development of the Company’s NLRP3 inhibitors in cardiometabolic diseases.

• VTX3232 in Parkinson’s Disease: Enrollment is progressing in the ongoing Phase 2 biomarker and imaging trial of VTX3232 in participants with early Parkinson’s disease. This trial is expected to enroll approximately 10 participants for a 28-day open-label treatment period. Key endpoints include safety, pharmacokinetics, and biomarkers in cerebrospinal fluid (CSF) and plasma. The trial also includes exploratory TSPO PET imaging as a marker of microglial activation. Topline results are expected in the first half of 2025.
  
  In a disease as complex as human Parkinson’s disease, the regulatory networks in microglia and other neural cell types linking the pathological consequence of NLRP3-mediated neuroinflammation to the progression of Parkinson’s disease are still unclear. However, overexpression of IL-1b and IL-18 has been observed in CSF samples from Parkinson’s disease patients, suggesting NLRP3 inhibition in the CNS may offer a disease-modifying therapeutic approach.
  
  The Phase 2 trial of VTX3232 in early Parkinson’s disease is designed to generate data in support of this therapeutic hypothesis by demonstrating the ability to modulate key inflammatory and disease-related biomarkers in the CSF, downstream of NLRP3 activation. Beyond Parkinson’s disease, NLRP3 inhibition in the CNS may have therapeutic utility in a range of neurodegenerative diseases with high unmet medical need, including Alzheimer’s disease, multiple sclerosis, and amyotrophic lateral sclerosis, among others.

Inflammatory Bowel Disease (IBD) Portfolio:

• Tamuzimod (VTX002, S1P1R Modulator, ulcerative colitis): Phase 2 long-term extension (LTE) data presented in October 2024 at the United European Gastroenterology Week meeting continue to reinforce the potential best-in-class profile of tamuzimod in ulcerative colitis (UC). While tamuzimod achieved high rates of clinical and endoscopic remission, a therapeutic ceiling may have been reached with monotherapies. Combination treatment is an emerging therapeutic concept in IBD, and its efficacy and safety profile could position tamuzimod as the backbone of future combination regimens with another oral or biologic agent. The Company continues to explore partnership opportunities for tamuzimod in ulcerative colitis.
  
  
• VTX958 (TYK2 Inhibitor, Crohn’s disease): As previously announced, in a Phase 2 trial, VTX958 did not meet the primary endpoint of change from baseline in the Crohn’s Disease Activity Index (symptomatic outcome) due to an abnormally high placebo response. VTX958 did demonstrate robust, dose-dependent, nominally statistically significant endoscopic response at Week 12 as measured by Simple Endoscopic Score-Crohn’s Disease (SES-CD; an objective endpoint) and showed a greater magnitude of decrease compared to placebo in two key biomarkers of inflammation, CRP and fecal calprotectin. Recognizing the opportunity for a safe and effective oral TYK2 inhibitor as early-line therapy in Crohn’s disease, we are continuing the analysis of the Phase 2 data including data from the 52-week treat-through LTE phase. Full analysis of the Phase 2 data is expected to inform a future development strategy for VTX958 in Crohn's disease, including potential partnership opportunities.
