The MIRACLE trial is for patients who have been newly diagnosed with moderate to severe ulcerative colitis in the last 12 months and who have not responded adequately to treatment with mesalazine and prednisolone alone.

The MIRACLE trial is for patients who have been newly diagnosed with moderate to severe ulcerative colitis in the last 12 months and who have not responded adequately to treatment with mesalazine and prednisolone alone. The standard drug therapy for ulcerative colitis begins with mesalazine (+cortisone) and, if the response is insufficient, continues with azathioprine (+cortisone). Only in the next step are biologics (biotechnologically produced protein substances such as antibodies) such as mirikizumab used as needed. Recent studies have now shown that earlier treatment with mirikizumab without prior treatment with azathioprine may be more effective in the long term, and there are indications that this may result in fewer side effects. This study aims to investigate whether direct, early treatment with mirikizumab is more effective than the usual initiation of standard therapy with azathioprine, whereby these patients can then switch to mirikizumab at predetermined times during the course of the study from week 24 onwards if they have a defined disease activity despite the previous azathioprine treatment. The study consists of an initial treatment period of 12 weeks (induction therapy) and a maintenance therapy period of 40 weeks. Patients in the mirikizumab arm receive 12 doses of mirikizumab. This includes initially 300 mg intravenously every 4 weeks at the trial site, followed by 200 mg subcutaneously via two subcutaneous injections of 100 mg each, administered independently at home. In the azathioprine arm patients receive daily administration of azathioprine tablets in combination with a steroid. Assignment to one of the two treatment options is randomised with equal probability for each of the treatment options.
