History
Summarize
Perspective
Mirikizumab was developed by Eli Lilly and Company.[11]
The approval was based on the LUCENT 1 clinical study which evaluated the safety and efficacy of mirikizumab in participants with moderately to severely active ulcerative colitis (UC) who have had an inadequate response to, loss of response, or intolerant to conventional or biologic therapy for UC.[12]
All participants enrolled in the program had a diagnosis of UC for at least three months prior to baseline and a confirmed diagnosis of moderately or severely active UC, as assessed by the modified Mayo score (MMS).[13][12][14]
After twelve weeks of induction treatment, 24% of participants on mirikizumab achieved clinical remission, which compared with 15% for those on a placebo. During the maintenance phase, 66% of mirikizumab takers who had achieved remission at twelve weeks stayed in remission through one year of treatment. Among those who achieved clinical response at twelve weeks, 51% of all mirikizumab-treated participants remained in clinical remission at one year, compared to 27% of those on placebo. Additionally, 99% who achieved clinical remission at one year were steroid-free, and 39% had achieved resolution or near resolution of bowel urgency, which is reported by UC participants as one of the most disruptive symptoms of the condition.[14][15]
