NCT06626165

Brief Summary

The goal of this study is to confirm that Mirikizumab therapy may provide clinical, endoscopic, and histopathologic improvements in patients with moderate to severe UC refractory to maintenance therapy when high neutrophilic infiltration in epithelium of the colonic mucosa (Geboes score Grade ≥3.2) on endoscopic biopsy is found.

Outcome Measures

Primary Outcomes (1)

  • Changes in clinical activities before and after mirikizumab or vedolizumab treatment.

    Clinical activity is graded using the clinical activity index (0, best - 15, worst).

    2 weeks

Secondary Outcomes (2)

  • Changes in endoscopic activities before and after mirikizumab or vedolizumab administration.

    2 months

  • Changes in pathological activity

    2 months

Study Arms (2)

Mirikizumab

ACTIVE COMPARATOR

When the patients were endoscopically active and pathologically high neutrophil infiltration in epithelium of the colonic mucosa (Geboes score Grade ≥3.2), using Geboes biopsy histology scores they will be administered by mirikizumab.

Drug: Mirikizumab

Vedolizumab

ACTIVE COMPARATOR

When the patients are endoscopically active and pathologically low neutrophil infiltration in epithelium of the colonic mucosa (Geboes score Grade 3.1), using Geboes biopsy histology scores, they will be administered by vedolizumab.

Drug: Vedolizumab

Interventions

Mirikizmgab will be administered based on the result of Geboes score Grade ≥ 3.2.

Mirikizumab

Vedolizmab will be administered based on the result of Geboes score Grade 3.1.

Vedolizumab
