Abstract
Background: Psoriasis is a chronic disease requiring long-term treatment strategies. Optimal strategies should include initial rapid relief of symptoms followed by long-term management to maintain remission. This 4-week open-label phase of a long-term proactive management phase 3 trial aimed to select responders to once daily, fixed-dose combination calcipotriene 0.005% and betamethasone dipropionate 0.064% (Cal/BD) foam in adults with psoriasis and assess patient-reported outcomes.
Method: This phase 3 trial in adults with psoriasis included a 4-week open-label lead-in phase to determine treatment success prior to entering the randomized maintenance phase. Success was defined as Physician Global Assessment (PGA) score ‘clear’/‘almost clear’ (PGA <2) with ≥2-grade improvement from baseline. Those achieving treatment success at week 4 entered the maintenance phase; non-responders were withdrawn from the trial.
Results: 650 patients enrolled in the open-label phase, and 623 were treated with Cal/BD foam for 4 weeks; 521 (80%) patients achieved treatment success and were included in the maintenance phase. In those patients achieving success (responders), 21.1% and 78.9% achieved a PGA score of ‘clear’ and ‘almost clear’, respectively. Mean change from baseline in modified Psoriasis Area and Severity Index (± standard deviation [SD]) and body surface area (± SD) in responders at week 4 was −82.1% (16.4%) and −56.6% (38.3%), respectively. Mean Dermatology Life Quality Index score reduced by 6.0 from baseline to week 4 (n=521). 17.7% of patients experienced AEs; with only one severe AE reported.
Conclusion: Cal/BD foam was highly efficacious and well tolerated during the 4-week lead-in phase of PSO-LONG.

INTRODUCTION

Plaque psoriasis, or psoriasis vulgaris, is a chronic, debilitating, inflammatory disease,1,2 characterized by well-defined erythemato-squamous plaques surrounded by normal skin.2 Various treatments are available for psoriasis, including topical treatment (considered first-line treatment) for mild-to-moderate disease and phototherapy or systemic/biologic agents (considered first- or second-line treatment) for moderate-to-severe disease.1

Despite the numerous treatment options for psoriasis, maintaining long-term control remains a challenge, due to the relapsing nature of the disease, and many patients remain untreated or undertreated.3 Currently, topical psoriasis treatment relies on a reactive approach to disease relapses, as opposed to a long-term proactive management approach aimed at maintaining disease remission.4 Psoriasis is a chronic disease that requires a safe long-term treatment strategy.
