Abstract

Objective Mirikizumab, a monoclonal antibody targeting the interleukin-23 p19 subunit, was effective in a Phase 2 study (NCT02589665) of moderately-to-severely active ulcerative colitis (UC). We studied mirikizumab's impact on health-related quality of life (HRQoL). Design HRQoL was evaluated using the Inflammatory Bowel Disease Questionnaire (IBDQ) and 36-Item Short Form Health Survey (SF-36) Physical Component Score (PCS) and Mental Component Score (MCS). Mixed effects models for repeated measures compared score changes between mirikizumab and placebo groups. Additional analyses evaluated associations between HRQoL score changes and achievement of efficacy endpoints at weeks 12 and 52. Results At week 12, IBDQ improved compared with placebo for all mirikizumab groups except mirikizumab 50 mg (50 mg, p=0.073; 200 mg, p<0.001; 600 mg, p<0.001). SF-36 PCS was significantly higher in all mirikizumab groups at week 12 (50 mg, p=0.011; 200 mg, p=0.022; 600 mg, p=0.002); MCS was significantly higher in mirikizumab 200 and 600 mg groups compared with placebo (50 mg, p=0.429; 200 mg, p=0.028; 600 mg, p<0.001). Achievement of clinical response and remission were associated with greater HRQoL improvements at week 12. Improvements in HRQoL scores were sustained through week 52. Of the clinical symptoms evaluated, reduction in rectal bleeding was associated with greater improvements in IBDQ and SF-36 scores. Conclusion Mirikizumab improved HRQoL in patients with moderately-to-severely active UC.
