Disease response and patient-reported outcomes among initiators of ixekizumab

Abstract

Objectives There is limited real-world evidence on using ixekizumab in psoriasis patients. Therefore, we characterized patients with psoriasis initiating ixekizumab and report 6-month changes in disease and patient-reported outcomes. Methods Adult patients with psoriasis who initiated ixekizumab and completed a 6-month follow-up visit were enrolled from the Corrona Psoriasis Registry. Disease characteristics and outcomes were assessed at ixekizumab initiation. Outcomes included the mean 6-month change in Psoriasis Area and Severity Index (PASI), body surface area (BSA), Investigator Global Assessment (IGA), and IGA*BSA. Results From baseline to follow-up in all patients (n = 136), means decreased for IGA*BSA (−45.5) and BSA (−12.4), and a higher % achieved an absolute PASI ≤ 5 (84.6%), BSA 0–3 (72.1%), and IGA 0/1 (50.7%). Within stratified groups, means decreased for PASI <12 for IGA*BSA (−21.1) and BSA (−6.3); PASI≥12 for IGA*BSA (−94.8) and BSA (−24.6); weight <100 kg for IGA*BSA (−45.1) and BSA (−12.4); weight ≥100 kg for IGA*BSA (−46.2) and BSA (−12.3); concomitant PsA for IGA*BSA (−56.0) and BSA (−15.3); and in no concomitant PsA for IGA*BSA (−36.9) and BSA (−10.0). Conclusions We provide real-world evidence on the benefits of ixekizumab for treating psoriasis, regardless of baseline disease severity, weight, or concomitant PsA.
