Patient and Healthcare Professional Satisfaction, Acceptability, and Preference Experiences With Mirikizumab Administration for Ulcerative Colitis: An International Survey.

Background: There is a need to better understand ulcerative colitis (UC) patient and healthcare provider (HCP) treatment satisfaction, acceptability, and preferences.

Methods: Two international, cross-sectional, web-based surveys were conducted among participants of a phase 3 mirikizumab study (NCT03519945). The questions captured moderate-to-severe UC patients' experience, HCPs' perception of patients' experience, and HCPs' own experience with mirikizumab administration through intravenous (IV) infusions and subcutaneous (SC) injections.

Results: Respondents included 93 patients and 42 HCPs from 11 countries. The majority of patients had UC >4 years (74.2%), were bionaive (68%), in remission at the time of the survey (63%). HCPs were primarily from the United States (57%), generally nurses (41%) or gastroenterologists (26%) with ≥6 years of experience in treating UC (57%). Most patients were "very satisfied/satisfied" (IV, 83%; SC, 91%), "completely/somewhat" accepting of mirikizumab administration (IV, 87%; SC, 97%), and agreed that improvement to their UC outweighed any administration dissatisfaction (90%). HCPs' perspectives of patients' experiences were higher: "very satisfied/satisfied" (IV, 93%; SC, 100%); "completely/somewhat" accepting (IV, 90%; SC, 98%). HCPs themselves were "very satisfied/satisfied" (IV, 81%; SC, 95%); gastroenterologists were "very satisfied" (IV, 82%; SC, 82%) more than nurses (IV, 29%; SC, 65%) who were generally at least "satisfied" (IV, 53%; SC, 35%). Two SC and monthly SC injections were "completely acceptable" by the patients (76% and 85%) and per HCPs' perceptions of patients' preferences (69% and 100%).

Conclusions: Both patients and HCPs were satisfied with and accepted mirikizumab IV induction followed by monthly maintenance SC injections. UC improvement outweighed any administration dissatisfaction.
