VTX958 was well-tolerated across all SAD and MAD cohorts with an excellent safety profile
Class-leading target coverage, with TYK2 IC50 and IC90 coverage up to 24 hours
Robust dose-dependent pharmacodynamic activity and evidence of target engagement as measured by in vivo IFNα challenge and ex vivo IL-12/IL-18 stimulation assays
ENCINITAS, CA, USA I August 15, 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 positive data from the company’s Phase 1 single ascending dose (SAD) and multiple ascending dose (MAD) trial of VTX958, a novel and selective allosteric TYK2 inhibitor.
The VTX958 Phase 1 SAD/MAD clinical trial was a two-part, randomized, double-blind, placebo-controlled dose-escalation study designed to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of single and multiple ascending doses. The study enrolled 96 adult healthy volunteers.
VTX958 Was Well Tolerated Across All Dose Groups
VTX958 was well tolerated across all 7 cohorts in the SAD portion and all 5 cohorts in the MAD portion of the Phase 1 trial with no discontinuations due to adverse events. No drug-related serious adverse events (SAEs) were reported. All treatment emergent adverse events (TEAEs) were classified as mild. No dose-limiting toxicities were identified and no dose-dependent trend in the frequency of TEAEs was observed. Additionally, there were no significant effects on hematological parameters, lipids/triglycerides and CPK laboratory values.
VTX958 Demonstrated a Dose-Dependent Increase in Exposure and Target Coverage
In both the SAD and the MAD portions of the trial, a dose-dependent increase in exposure was observed through all cohorts. In the MAD portion of the trial, VTX958 achieved TYK2 IC50 and IC90 coverage up to 24 hours. The exposures achieved by VTX958 demonstrated class-leading coverage of TYK2 IC50 and IC90 and its target cytokines, IL-12, IL-23 and IFNα.a
VTX958 Demonstrated Dose-Dependent Pharmacodynamic Effects
In the MAD portion of the trial, pharmacodynamic (PD) activity was measured by the impact on TYK2-mediated target genes following an in vivo IFNα challenge, and by the IFNγ response to ex vivo IL-12/IL-18 stimulation of blood samples derived from all dosing cohorts. In both the in vivo IFNα challenge PD assay, as well as the ex vivo IFNγ response assay, VTX958 demonstrated robust dose-dependent PD, thereby confirming its impact on TYK2-mediated pathways and providing direct in vivo evidence of target engagement.
Planned Phase 2 Trials
“Data from the Phase 1 trial of VTX958 demonstrate an excellent safety profile and class-leading TYK2 inhibition as measured by IC50 and IC90 coverage,” said William Sandborn, MD, President and Chief Medical Officer. “We believe these data will allow us to explore high levels of target inhibition in future clinical studies, which may support clinical differentiation in relevant disease populations, such as psoriasis, psoriatic arthritis and lupus. Additionally, we believe that our ability to achieve TYK2 target coverage throughout the day at levels typically associated with biologic therapies, may position VTX958 for success in disease indications that are expected to require higher therapeutic doses, such as Crohn’s disease. We look forward to advancing VTX958 into multiple Phase 2 trials, including psoriasis, Crohn’s disease and psoriatic arthritis, beginning in the fourth quarter of 2022.”

About VTX958 and TYK2 Inhibition
VTX958 is an oral, selective allosteric inhibitor of tyrosine kinase 2 (TYK2). TYK2 regulates both innate and adaptive immunity by mediating IFNα, IL-12 and IL-23 signaling. These targets have been clinically validated as relevant in the treatment of a broad range of immune-mediated diseases, including psoriasis, psoriatic arthritis, Crohn’s disease, ulcerative colitis and lupus. Selectively targeting inhibition of TYK2 without inhibition of other JAK family enzymes may reduce inflammation while preserving protective immune function. VTX958 was internally discovered and all commercial rights to the compound are owned by Ventyx.
