Abstract Background Preventing Crohn’s disease (CD)-related hospitalizations and surgeries is a recommended goal in disease-modification trials preventing disease progression (SPIRIT Consensus)1. The VIVID-1 study (NCT03926130) demonstrated the efficacy and safety of mirikizumab (MIRI), a humanized antibody selectively targeting the Interleukin-23 p-19 subunit, for the treatment of CD2. Here we assessed the impact of MIRI on CD-related hospitalization and surgery rates in VIVID-1 participants. Methods This post-hoc analysis included patients randomized to MIRI or placebo (PBO) (6:2). MIRI-treat through patients received MIRI 900mg every 4W during induction phase (W0-12) and MIRI 300mg every 4W during maintenance phase (W12-52). PBO/PBO responders received PBO through W12 and were continued on PBO through W52 (Fig 1A). Baseline demographics groups were analyzed by occurrence (with) or absence (without) hospitalizations or surgeries during induction. The proportion of patients with CD-related hospitalization and/or surgery was calculated with a 95% confidence interval. Incidence rates (IRs) were also reported as exposure-adjusted hospitalization and/or surgery events per 100 patient-years. Results At baseline, CD duration, ileal disease location, Crohn’s Disease Activity Index (CDAI) total score, C-Reactive Protein (CRP)-levels, and prior biologic failure proportions were numerically higher in PBO and MIRI groups with CD-related hospitalizations/surgeries than without. (Table 1). Proportions of patients with CD-related hospitalizations and surgeries were reduced in MIRI vs PBO patients (hospitalizations or surgeries: 4.1% vs 7.5% W12 and 3.3% vs 9.8% W52) (Fig 1B and C). Furthermore, from W0 to W12, IR of patients with CD-related hospitalizations and surgeries were lower in the MIRI-treated group (hospitalizations: 16.9%, surgeries: 2.2%, hospitalizations or surgeries: 17.7%) compared to the PBO-treated group (IRs: hospitalizations: 28.7%, surgeries: 8.6%, hospitalizations or surgeries: 33.2%). From W12 to W52, the IR of patients with CD-related hospitalizations or surgeries decreased in the MIRI treat-through group (hospitalizations: 4.2%, surgeries: 1.0%, hospitalizations or surgeries: 4.5%) while increasing in PBO/PBO responders who were clinical responders in the induction period and continued on PBO during the maintenance period (hospitalizations: 14.0%, surgeries: 6.1%, hospitalizations or surgeries: 15.7%). Conclusion CD-related hospitalizations/surgeries were associated with longer CD duration, ileal disease location, and higher disease severity at baseline. MIRI treatment reduced proportions and IR of CD-related hospitalizations and/or surgeries through 1 year of treatment vs PBO, supporting the already known benefit/risk of MIRI.
