OBJECTIVE

To describe the results of a systematic literature review of real-world outcomes with ixekizumab in psoriasis (PsO), psoriatic arthritis (PsA), or axial spondyloarthritis (axSpA).

METHODS

Databases, conference proceedings, and additional sources were searched for real-world studies in ≥ 25 patients treated with ixekizumab for PsO, PsA, or axSpA. Data on clinical effectiveness, patient-reported outcomes, treatment patterns, safety, and economic burden were extracted.

RESULTS

A total of 118 publications were included, 96 in PsO, 16 in PsA, 5 in both PsO and PsA, and 1 in axSpA. Most focused on clinical effectiveness and treatment patterns. Ixekizumab was effective in real-world settings, and the anti-interleukin (IL)-17A biologics were more effective for skin clearance than comparator biologics. Anti-IL-17A biologics were effective for challenging body areas (nails, scalp, genitals, palmoplantar regions), and ixekizumab was associated with a higher chance of obtaining Dermatology Life Quality Index scores of 0/1 than secukinumab or other biologics. Ixekizumab was associated with generally high persistence/drug survival. No unexpected safety signals were identified.

CONCLUSION

Real-world ixekizumab use for PsO and PsA is effective and safe, with a positive impact on patient quality of life. More data are needed to draw conclusions for real-world ixekizumab use in axSpA.
