This is a one-arm, open-label study to examine the effect of deucravacitinib on cutaneous and blood immune cells of psoriatic patients. 25 subjects with moderate to severe psoriasis will be enrolled. Biopsy and blood samples will be collected before and during treatment and undergo molecular profiling to assess for deucravacitinib-corrected signatures.
This study aims to assess cutaneous and blood immune cell function of patients with psoriasis before and after initiation of treatment with the Tyrosine kinase 2 (TYK2) blocker, deucravacitinib.
