The Phase 2 trial in psoriasis will explore a broad range of doses based on Phase 1 data demonstrating class-leading safety and TYK2 target coverage

Phase 2 trials of VTX958 for psoriatic arthritis and Crohn’s disease are on track to initiate by year end

ENCINITAS, CA, USA I December 01, 2022 I Ventyx Biosciences, Inc. (Nasdaq: VTYX) (“Ventyx”), a clinical-stage biopharmaceutical company focused on advancing novel oral therapies that address a range of inflammatory diseases with significant unmet medical need, today announced that the first patient has been dosed in a Phase 2 trial of its selective, allosteric TYK2 inhibitor VTX958 for the treatment of moderate to severe plaque psoriasis.

“Dosing of the first patient in the Phase 2 SERENITY trial of VTX958 is a major accomplishment for Ventyx and an important step towards providing a new treatment option for patients suffering from moderate to severe plaque psoriasis who are in need of more effective oral therapies,” said Dr. William Sandborn, President and Chief Medical Officer. “Our Phase 1 single-ascending dose and multiple-ascending dose data established an excellent safety profile with dose-dependent pharmacokinetic and pharmacodynamic data supporting class-leading target coverage of TYK2-mediated pathways. The wide therapeutic window of VTX958 observed in our Phase 1 trial will allow us to explore a broad range of doses in Phase 2 trials, including doses designed to achieve biologic-like IC90 coverage of TYK2-mediated cytokines, such as IL-23. Topline data from the Phase 2 SERENITY trial are expected in the fourth quarter of 2023. We plan to provide further updates across our wholly-owned development pipeline, including our three Phase 2 trials of VTX958, at our R&D day on January 26, 2023.”

The Phase 2 SERENITY trial is a randomized, double-blind, placebo-controlled, dose-ranging trial to evaluate the safety and efficacy of VTX958 in patients with moderate to severe plaque psoriasis. The trial will enroll approximately 200 patients randomized to one of four VTX958 doses or placebo for a 16-week double-blind treatment period. The primary efficacy endpoint will evaluate the proportion of subjects achieving a 75% reduction in the Psoriasis Area and Severity Index (PASI-75) at week 16.

In addition to the SERENITY Phase 2 trial, Ventyx is on track to initiate two additional Phase 2 trials of VTX958 in psoriatic arthritis and Crohn’s disease before the end of the year.
