Efficacy and safety of apremilast in patients with mild-to-moderate plaque psoriasis: Results of a phase 3, multicenter, randomized, double-blind, placebo-controlled trial

Background: Patients with mild-to-moderate psoriasis may have substantial quality-of-life impairment. Objective: To evaluate apremilast 30 mg twice daily for mild-to-moderate psoriasis. Methods: Phase 3, double-blind, placebo-controlled study in adults with mild-to-moderate psoriasis inadequately controlled or intolerant to >= 1 topical psoriasis therapy (NCT03721172). The primary endpoint was the achievement of static Physician Global Assessment score of 0 (clear) or 1 (almost clear) and >= 2-point reduction at week 16. Results: Five hundred ninety-five patients were randomized (apremilast: 297; placebo: 298). The primary endpoint was met, with a significantly greater static Physician Global Assessment response rate observed at week 16 in the apremilast group compared with the placebo group (21.6% vs 4.1%; P < .0001). All secondary endpoints were met with the achievement of body surface area-75 (33.0% vs 7.4%), body surface area <= 3% (61.0% vs 22.9%), >= 4-point reduction in Whole Body Itch Numeric Rating Scale (43.2% vs 18.6%), Scalp Physician Global Assessment 0 or 1 and >= 2-point reduction (44.0% vs 16.6 %), and changes from baseline in body surface area, Psoriasis Area and Severity Index, and Dermatology Life Quality Index (all P < .0001). The most commonly reported adverse events (>= 5%) with apremilast were diarrhea, headache, nausea, nasopharyngitis, and upper respiratory tract infection, consistent with prior studies. Limitations: The study lacked an active-comparator arm. Limitations: The study lacked an active-comparator arm. Conclusion: Apremilast demonstrated efficacy in mild-to-moderate psoriasis and safety consistent with the established safety profile of apremilast.
