Abstract
Introduction: Deucravacitinib, an oral, selective, allosteric tyrosine kinase 2 inhibitor, is approved in the US and other countries for the treatment of adults with moderate-to-severe plaque psoriasis who are candidates for systemic therapy or phototherapy. In the POETYK PSO-1 (NCT03624127) and PSO-2 (NCT03611751) trials, deucravacitinib was superior to placebo and apremilast in patients with moderate to severe plaque psoriasis. This analysis evaluated deucravacitinib efficacy by baseline characteristics.
Methods: Efficacy endpoints, including ≥75% reduction from baseline in Psoriasis Area and Severity Index (PASI 75) and static Physician’s Global Assessment score of 0 (clear) or 1 (almost clear) (sPGA 0/1), were evaluated at Week 24 by baseline subgroups including weight, sex, and PASI in the pooled PSO-1 and PSO-2 population, and at Week 52 in PSO-1 patients who received continuous deucravacitinib treatment from Day 1.
Results: In the pooled PSO-1 and PSO-2 population, deucravacitinib (n=843) was more efficacious than apremilast (n=422) at Week 24 across subgroups defined by baseline weight (<90 kg: PASI 75, 69.8% vs 43.8%, sPGA 0/1, 60.2% vs 34.2%; ≥90 kg: PASI 75, 55.4% vs 31.5%, sPGA 0/1, 45.9% vs 25.6%), sex (male: PASI 75, 59.3% vs 33.7%, sPGA 0/1, 49.6% vs 24.7%; female: PASI 75, 70.4% vs 45.2%, sPGA 0/1, 60.9% vs 39.4%), and PASI (≤20: PASI 75, 61.6% vs 38.6%, sPGA 0/1, 53.5% vs 32.4%; >20: PASI 75, 64.7% vs 37.0%, sPGA 0/1: 53.2% vs 27.1%). Consistent efficacy was observed through Week 52 in patients who received continuous deucravacitinib treatment in PSO-1 (n=332), regardless of baseline characteristics.
Conclusion: Deucravacitinib demonstrated consistent efficacy for up to 52 weeks regardless of baseline characteristics in patients with moderate to severe plaque psoriasis.
