Adults aged 18 years or older with a diagnosis of moderate to severe psoriasis for 6 months or more are needed for this clinical research trial. Eligible participants must have plaque psoriasis covering ≥ 10% of body surface area (BSA).
Participants will receive investigational oral medication (active study drug) or placebo via a tablet. The investigational medication and study-related assessments will be provided at no cost. Reimbursement for study-related expenses may be provided.
Study participation will last about 24 weeks and involve about 8 visits to the study center.

This is a study to understand if taking VTX958 daily orally is safe and effective in participants diagnosed with moderate to severe psoriasis (PsO). Approximately 200 patients will take VTX958 Dose A, VTX958 Dose B, VTX958 Dose C, VTX958 Dose D, or placebo. The study consists of a 30-day Screening Period (to see if a participant qualifies for the study), a 16-week double-blind period (a participant receives active Dose A, Dose B, Dose C, Dose D, or placebo), and a 4-week Follow-Up Period. The maximal duration of treatment will be 4 months
