Key clinical point: Dermatological symptoms are substantially associated with the quality of life (QoL) in patients with active psoriatic arthritis (PsA) and improvements in dermatology measures could translate to clinically meaningful improvements in their QoL.
Major finding: Itch severity item (ISI) scores of 7-10, Physician’s Global Assessment of Psoriasis (PGA-PsO) scores of 4, and Patient’s Global Joint and Skin Assessment-Visual Analog Scale (PGJS-VAS) scores of 90-100 mm corresponded with Dermatology Life Quality Index (DLQI) scores categorized as having a very large effect on a patient’s life. An improvement of ≥3 points in ISI, ≥2 points in PGA-PsO, and ≥40 mm in PGJS-VAS translated to a clinically meaningful improvement in DLQI scores.
Study details: This post hoc analysis of two phase 3 studies, OPAL Broaden and OPAL Beyond , included 816 patients with active PsA and an inadequate response to previous therapies who received tofacitinib, adalimumab, or placebo.
Disclosures: This study was funded by Pfizer. Four authors reported being employees or stockholders of Pfizer. The other authors reported ties with several sources, including Pfizer.
