AB0530 EFFECT OF SKIN SYMPTOMS ON DISEASE IMPACT IN PATIENTS WITH PSORIATIC ARTHRITIS RECEIVING THE IL-12/23 INHIBITOR USTEKINUMAB OR TNF INHIBITORS IN THE REAL-WORLD PSABIO STUDY
2021
Background: Psoriatic arthritis (PsA) is characterised by musculoskeletal symptoms, and patients (pts) with PsA usually experience psoriasis concurrently. Real-world data reflecting impact of skin symptoms on PsA disease burden are limited. Objectives: Analyse effectiveness of ustekinumab (UST) and tumour necrosis factor inhibitor (TNFi) therapy on extent of skin involvement, and the impact this has on PsA disease burden and drug persistence. Methods: PsABio (NCT02627768) is a prospective, observational study of 1st/2nd/3rd-line UST or TNFi treatment in PsA in 8 European countries. Extent of skin involvement was categorised as body surface area (BSA): clear/almost clear; 10%. Pt-reported disease impact was evaluated by PsAID-12, including assessment of two skin-related domains (D): D3 (skin problems, including itching) and D10 (embarrassment and/or shame because of appearance). Estimated persistence at 1 year was assessed across baseline (BL) BSA categories. Results: At BL, significantly more pts receiving UST than TNFi had BSA >10% (Figure 1). BL disease impact (PsAID-12) was worse in pts with BSA >10% than 10% (Figure 1). At 1 year, both treatments significantly reduced disease impact (PsAID-12 total), and D3 and D10 scores, irrespective of BL BSA category, but most markedly in pts with higher BL BSA (Table 1). Worse BL psoriasis was generally associated with longer persistence for both treatments; however, at 1 year, pts with BSA >10% had significantly shorter persistence with TNFi (mean [95% CI]: 361 [336; 387] days) than with UST (410 [394; 426] days). Conclusion: In PsA, interleukin-12/23 inhibition (UST) and TNFi therapy in routine care rapidly and substantially reduced extent of skin involvement and related disease impact. Pts with highest BL skin involvement had significantly longer drug persistence with UST than with TNFi. Together, PsABio data suggest that successful treatment of skin involvement in PsA with biologics reduces disease burden and may improve persistence, especially in pts with worse BL psoriasis.
