Efficacy and Safety of Apremilast in the Treatment of Patients with Mild-to-Moderate Psoriasis in Japan: Results from PROMINENT, A Phase 3b, Open-Label, Single-Arm Study
Аннотация:Patients with mild-to-moderate plaque psoriasis often experience reduced quality of life and increased disease burden due to itch or involvement of psoriasis in special areas such as the scalp and nails. Systemic therapy may be used concurrently with topical therapy in patients with active disease not controlled by topical therapy alone. The objective of PROMINENT was to evaluate the efficacy and safety of apremilast in combination with topical therapy in patients with mild-to-moderate psoriasis in Japan.PROMINENT, a phase 3b, open-label, single-arm study in Japan, enrolled adults ≥ 20 years of age with plaque psoriasis [static Physician Global Assessment (sPGA) 2 (mild) or 3 (moderate)] not adequately controlled by topical therapy. Patients received apremilast 30 mg twice daily for 16 weeks in addition to their existing topical therapy, with the option of topical therapy reduction at the discretion of their physician while continuing apremilast treatment from weeks 16 to 32.Of the 152 patients enrolled in the study, 136 completed week 32. The primary endpoint of sPGA response [score 0 (clear) or 1 (almost clear)] was achieved by 43.7% of patients at week 16, and 40.8% maintained response at week 32. Clinically meaningful improvements in skin, scalp, and nails were observed in > 40% of patients at weeks 16 and 32. Similarly, improvements in pruritus, quality of life, and treatment satisfaction were observed at week 16 and maintained at week 32. Common treatment-emergent adverse events through week 32 included gastrointestinal events, nasopharyngitis, and headache.Apremilast in combination with topical therapy resulted in clinically meaningful and sustained efficacy in physician- and patient-reported outcomes at weeks 16 and 32 in Japanese patients with mild-to-moderate psoriasis. Tolerability was consistent with available prior safety data for apremilast.ClinicalTrials.gov identifier, NCT03930186.
