Understanding characteristics of patients newly initiating ixekizumab: findings from the Corrona Psoriasis Registry.

Background: Real-world data on patients newly initiating ixekizumab is limited. Our study describes the characteristics of patients who initiated ixekizumab and other biologics for psoriasis treatment in North American dermatological practices. Materials & methods: Characteristics of patients ascertained at registry enrollment are described via means and frequencies. Results: Compared with other biologic initiators, ixekizumab initiators had: longer disease duration (17.1 vs 15.1 years); more were considered least severe by body surface area (33 vs 26%); moderate-to-severe by IGA (56 vs 48%); were biologic-experienced (80 vs 52%); obese (54 vs 47%); and experienced greater impact in work productivity (5.3 vs 2.9%) versus other biologic initiators. Conclusion: Psoriasis patients initiating ixekizumab had more severe disease, biologic experience, and worse patient-reported outcomes than those initiating other biologics.
