Deucravacitinib Improves Patient-Reported Outcomes in Patients with Moderate to Severe Psoriasis: Results from the Phase 3 Randomized POETYK PSO-1 and PSO-2 Trials.

INTRODUCTION

Deucravacitinib, a novel, oral, selective allosteric tyrosine kinase 2 inhibitor, demonstrated superiority versus placebo and apremilast in the POETYK PSO-1 and PSO-2 studies. We describe patient-reported outcomes with deucravacitinib treatment versus placebo and apremilast in these studies.

METHODS

Two multicenter, global, double-blind, placebo- and active comparator-controlled studies randomized patients with moderate-to-severe plaque psoriasis 1:2:1 to placebo, deucravacitinib 6 mg once daily, or apremilast 30 mg twice daily. Score changes from baseline and meaningful within-patient change responses for Psoriasis Symptoms and Signs Diary (PSSD) and Dermatology Life Quality Index (DLQI) were assessed.

RESULTS

In POETYK PSO-1 (n = 666) and PSO-2 (n = 1020), respectively, improvement from baseline in PSSD total score was greater with deucravacitinib (- 27.8 and - 30.1) versus placebo (- 4.4 and - 5.9) and apremilast (- 18.9 and - 22.5) at Week 16 and versus apremilast at Week 24 (deucravacitinib: - 32.8 and - 30.7; apremilast: - 21.6 and - 22.8) (nominal p < 0.0001). Improvement from baseline in DLQI score was also greater with deucravacitinib (- 8.5 and - 7.6) versus placebo (- 3.3 and - 3.0) and apremilast (- 5.9 and - 5.8) at Week 16 and versus apremilast at Week 24 (deucravacitinib: - 8.6 and - 7.5; apremilast: - 5.6 and - 5.5) (nominal p < 0.0001). Achievement of meaningful within-patient change in PSSD total score and in DLQI score occurred more frequently with deucravacitinib than placebo and apremilast at Week 16 and versus apremilast at Week 24.

CONCLUSIONS

Deucravacitinib demonstrated meaningful improvements in patient-reported outcomes in patients with moderate-to-severe plaque psoriasis compared with apremilast and placebo.
