Ventyx Expands Global Phase 2 Study for VTX2735 and Strengthens Advisory Team Ahead of Key Data Milestones
International Study Expansion and New Advisors Signal Strategic Shifts for Ventyx
Ventyx Biosciences is stepping up its game in inflammation-targeted therapies, expanding its Phase 2 study of VTX2735—an oral NLRP3 inhibitor for recurrent pericarditis—into Canada, the European Union, and the UK. The move is complemented by a leadership boost, as the company welcomes industry leaders Mark McKenna as Strategic Advisor and Dr. Peter Libby as Clinical Advisor.
Expanded Study Brings Global Scope and Dosing Flexibility
Previously limited to the US, the Phase 2 trial of VTX2735 will now recruit patients internationally, increasing its statistical power and future regulatory leverage. The study also transitions to a once-daily (QD) dose, replacing the previous twice-daily regimen. The QD cohorts will have their primary endpoint assessed at six weeks and an extended follow-up to 24 weeks, up from 13. These design tweaks are expected to streamline patient recruitment and accelerate the development timeline for a global Phase 3 trial.
| Key Change | Details |
|---|---|
| Study Expansion | Now includes Canada, EU, and UK |
| Dosing Update | Switching from twice-daily (150 mg BID) to once-daily (QD) formulation |
| Primary Endpoint Assessment | Remains at 6 weeks for QD cohorts; extension up to 24 weeks |
| Topline Data Timeline | Interim results pushed to Q1 2026 |
Clinical Advisors Bolster Scientific and Strategic Credibility
Ventyx's addition of Mark McKenna, the architect behind the $10.8 billion Merck acquisition of Prometheus Biosciences, and Dr. Peter Libby, a cardiovascular inflammation authority, is a notable move. McKenna's precision medicine background and Libby’s deep expertise in vascular inflammation will provide critical guidance as Ventyx moves its oral NLRP3 inhibitor portfolio—including both VTX2735 for pericarditis and VTX3232 for CNS disorders—through late-stage clinical trials.
Focus on Recurrent Pericarditis: Meeting an Unmet Need
Recurrent pericarditis remains a painful, difficult-to-treat heart condition. By inhibiting the NLRP3 inflammasome, VTX2735 is designed to tackle the root cause of inflammation, aiming not only to relieve acute symptoms but to prevent relapses. The expanded Phase 2 trial is testing safety, pain reduction (as measured by NRS score), and biomarker response (high sensitivity C-reactive protein or hsCRP).
| Trial Metric | Description |
|---|---|
| Population | Severe recurrent pericarditis patients (Phase 2, NCT06836232) |
| Endpoints | Safety, pain (NRS score), hsCRP biomarker |
| Dose Regimen | Initial 150 mg BID; switching to QD formulation |
| Extension Period | Up to 13 weeks (BID); up to 24 weeks (QD) |
Looking Ahead: Interim Data to be Revealed at 2026 R&D Day
The company is now targeting its Research & Development Day in Q1 2026 to reveal interim results for VTX2735’s Phase 2 trial. Alongside topline efficacy and safety data, Ventyx plans to share in-depth analyses of the new QD formulation’s pharmacokinetics and pharmacodynamics, as well as broader portfolio updates. While the timing is slightly later than previously guided, the adjustments position the program for a potentially faster Phase 3 launch.
Takeaway: More Than Just a Study Update—Strategic Moves Set Up Pivotal Year
By broadening the trial footprint, updating its dosing approach, and bolstering its advisory team, Ventyx is methodically advancing its platform. While delays are always a risk in clinical development, the next 12 months look pivotal for both VTX2735 and the company's broader ambitions in immunology. Investors and healthcare stakeholders may want to mark their calendars for early 2026 as Ventyx reveals the data that could shape its future direction.
