This pooled analysis of the Phase 3 PSO-1 and PSO-2 trials shows that deucravacitinib has greater efficacy in treating scalp PsO than placebo and apremilast. At week 16, response rates were greater with deucravacitinib versus placebo or apremilast for scalp-specific Physician Global Assessment 0/1 and Psoriasis Scalp Severity Index. Efficacy was maintained through 52 weeks in patients who received continuous deucravacitinib treatment.
