Adalimumab in the management of psoriasis and psoriatic arthritis: Results from a Delphi investigation.

Abstract

Psoriasis (PsO) and psoriatic arthritis (PsA) are often undertreated and require a multidisciplinary approach. In recent years, patent expiration has allowed the introduction of tumor necrosis factor inhibitor (anti-TNF) biosimilars, which have stimulated a significant increase in the use of biological therapies. This article reports the findings of a multidisciplinary approach to achieve a consensus on the use of adalimumab in patients with PsO or PsA. A voting panel of 36 Italian dermatologists and rheumatologists were chosen by eight Italian clinicians (the Board), to provide a consensus on the real-world management of PsO and PsA with adalimumab using the Delphi Method, comprising three survey rounds. Twelve statements were defined by the Board and submitted to the panel (rating scale 1-7). Clinicians reached a wide consensus on the effectiveness (score 6-7: 67%) and long-term efficacy (6-7: 100%) of adalimumab in all clinical forms of PsO and PsA, including pediatric patients (6-7: 85%). Considering cost-effectiveness and safety, adalimumab is suggested as a first-line treatment in patients with enthesitis, predominant peripheral arthritis, axial involvement or associated inflammatory bowel disease (IBD) or uveitis. Adalimumab can be also considered after failure of etanercept (6-7: 94%). Results from this Delphi study clearly show an overall consensus on the use of adalimumab in the management of PsO and PsA, particularly as first-choice for specific subpopulations (uveitis, IBD, hidradenitis suppurativa). Considering the cost-effectiveness of biosimilars within Italy, adalimumab may represent an effective and safe first-line treatment for patients with moderate-to-severe PsO or PsA, and a valid choice for switching after failure.
