ENCINITAS, Calif., Jan. 26, 2023 (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, is hosting an investor R&D Day today highlighting key aspects of Ventyx’s clinical-stage and discovery programs.

“I am thrilled to highlight progress across our diverse, wholly-owned pipeline of differentiated small molecule drug candidates following a year of tremendous progress,” said Raju Mohan, Chief Executive Officer. “2023 is shaping up to be a transformational year for Ventyx with several key clinical readouts anticipated, including topline Phase 2 data for VTX002 in ulcerative colitis, which is expected in H2 2023, and topline Phase 2 data for VTX958 in psoriasis, which is expected in Q4 2023. Meanwhile, our peripheral NLRP3 inhibitor VTX2735 is Phase 2 ready and we expect to initiate a Phase 1 trial for our CNS-penetrant NLRP3 inhibitor VTX3232 in H1 2023. Finally, we are excited to announce a new discovery-stage program to develop small molecule IL-4Rα antagonists. The progress made in this program showcases the strength of our discovery capabilities and further strengthens our novel, small-molecule immunology pipeline. We look forward to providing additional details on these programs at this event.”

Pipeline Updates and Anticipated Catalysts

VTX958 (TYK2 Inhibitor)

• Enrollment is ongoing in the Phase 2 SERENITY trial of VTX958 in moderate-to-severe plaque psoriasis and the Phase 2 HARMONY trial in Crohn’s disease, while screening activities have initiated for the Phase 2 TRANQUILITY trial in psoriatic arthritis. Topline data from the Phase 2 SERENITY psoriasis trial are anticipated in Q4 2023. Topline readouts from the Phase 2 HARMONY and Phase 2 TRANQUILITY trials are expected in 2024.
• We are developing an extended release (ER) tablet formulation for VTX958 in collaboration with leading formulation development partners. We expect to provide an update on the ER tablet development in mid-2023 following completion of in-human testing.

VTX002 (S1P1R Modulator)

• We continue to make significant progress enrolling the Phase 2 trial of VTX002 in moderate-to-severe ulcerative colitis. We expect to complete enrollment by mid-2023, and topline results are anticipated in the second half of 2023.
• Preliminary pharmacodynamic data from the open-label extension of the ongoing Phase 2 trial in ulcerative colitis may support the potential best-in-class profile of VTX002. Among patients completing Week 26 (13 weeks of blinded therapy followed by 13 weeks of open-label treatment with VTX002 60mg) as of January 15, 2023, a mean reduction from baseline in absolute lymphocyte count of 74% was observed. Reduction in absolute lymphocyte count is an important pharmacodynamic (PD) marker for efficacy in ulcerative colitis and we believe these preliminary data suggest VTX002 may achieve a stronger PD response compared to other S1P receptor modulators approved or in development for the treatment of ulcerative colitis.

VTX2735 (Peripheral NLRP3 Inhibitor)

• We are presenting additional data from the completed Phase 1 trial of VTX2735 in healthy volunteers, in which VTX2735 demonstrated excellent safety and target coverage. VTX2735 was well tolerated across all doses tested, with anticipated Phase 2 dose regimens expected to achieve IC₉₀ coverage of IL-1β for 20 hours or more. VTX2735 also exhibited dose- and concentration-dependent inhibition of IL-1β ex vivo and significant reductions from baseline in high sensitivity C-reactive protein.
• We have completed non-clinical toxicology studies and developed a solid oral dose (tablet) to position VTX2735 as a Phase 2-ready compound.
• A Phase 2 proof-of-mechanism trial of VTX2735 in cryopyrin-associated autoinflammatory syndromes is expected to initiate in Q1 2023.

VTX3232 (CNS-penetrant NLRP3 Inhibitor)

• We expect to file an IND and initiate a Phase 1 trial for VTX3232 during the first half of 2023. The Phase 1 trial is expected to characterize the safety, target engagement and bioavailability of VTX3232 in the central nervous system of healthy volunteers.

Discovery Programs

• We are introducing a new discovery-stage program focused on small molecule antagonists of IL-4Rα, a target validated by biologics in multiple large autoimmune indications, including atopic dermatitis, asthma and eosinophilic esophagitis. We are advancing multiple internally discovered novel chemical series through lead optimization with the goal of establishing in vivo proof-of-concept and nominating a lead candidate in 2023.
