ABSTRACT
Biologic dosing frequency is a key concern among psoriasis (PsO) patients and physicians, yet dosing optimization remains a challenge. This study evaluates patient dosing preferences for IL-17 and IL-23 inhibitors, risankizumab (RZB) every 12 weeks, guselkumab (GUS) every 8 weeks, and ixekizumab (IXE) every 4 weeks, in managing PsO. This phone survey study evaluated 87 adults on RZB (n = 29), GUS (n = 35), or IXE (n = 23) from 2019 onward at two clinical sites. Patients were assessed for baseline PsO bothersome severity, current dosing frequency satisfaction, frequency of PsO flares, and preferred dosing frequency. Most patients were males (57.5%) with an average age of 54.1 years and an average treatment duration of 19.0 months. At baseline before treatment, 87% were ‘very bothered’ by their PsO. After treatment, 86% were either ‘3-somewhat’ or ‘4-very satisfied’ with their current dosing schedule, with no significant differences between each drug (P = 0.7). Across all biologics the majority of participants (62% with RZB, 57% with GUS, and 48% with IXE) preferred maintaining their current dosing frequency. No statistically significant differences were observed in dosing frequency preference between treatment groups, suggesting dosing schedule is not a primary concern for most patients. This aligns with previous research demonstrating effective disease control is the most important factor for patient satisfaction; however, tailoring dosing regimens to individual patient needs can also strengthen long-term adherence, as demonstrated in recent studies.
