The goal of this clinical trial is to learn if mirikizumab works to treat pouch disorders in adults. The main questions it aims to answer are:
Does mirikizumab reduce symptoms of pouch disorders
Participants will:
Take mirikizumab every 4 weeks for one year Visit the clinic once every month for two months and at the end of the study Keep a diary of their symptoms

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
A score of how well the liver works in people with liver disease such as cirrhosis: class A is mild, B moderate and C severe.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Remission as measured by Modified Pouchitis Disease Activity Index (mPDAI)
The Pouchitis Disease Activity Index (PDAI) was developed for diagnosing active pouchitis and quantifying the severity of pouchitis. The PDAI includes the clinical criteria of 1) stool frequency 2) rectal bleeding 3) Fecal Urgency/Abdominal Cramps and 4) presence or absence of fever, endoscopic criteria, and histologic criteria through biopsies. The PDAI was modified to omit the biopsy and histology costs. The mPDAI includes the clinical portion and the endoscopic subscore of the PDAI. Score range is 0-12. The higher the score, the worse the disease activity. mPDAI remission is defined as an mPDAI score of 4 or lower and a reduction from baseline of 2 or more points in the mPDAI total score.
Time frame: Weeks 0, 24, and 52
Median change in the Endoscopic Pouch Score (EPS)
The endoscopic pouch score (EPS) is a standardized assessment of inflammation in the pouch of patients with an ileal pouch anal anastomosis (IPAA), including those with inflammation outside the pouch body. The EPS is a novel method of endoscopic scoring that has been developed to offer more granular longitudinal assessments of response to advanced therapies in patients with inflammatory conditions of the pouch. Score range is 0-45. The higher the score, the worse the disease activity.
Time frame: Weeks 0, 24, and 52
Median change in the endoscopic subscore of the mPDAI
The endoscopic subscore of the PDAI is a component of the PDAI that assesses endoscopic findings of pouchitis. Score range is 0-6. The higher the score, the worse the disease activity.
Time frame: Weeks 0, 24, and 52
Change in Cleveland Clinic Global Quality of Life (QoL) scale
The Cleveland Clinic Global Quality of Life scale asks the patient to rate their current QoL, current quality of health, and current energy level using a 1-10 rating (where 10 is best). The score on each of these 3 components is added and the final Cleveland Clinic Global Quality of Life utility score can be obtained by dividing this result by 30. A higher score means improved quality of life.
Time frame: Weeks 0, 4, 8, 12, 24, 38, and 52
Change in Patient-Reported Outcomes Measurement Information System (PROMIS) incontinence measures
The PROMIS measure for incontinence includes 4 items that assess the frequency of bowel incontinence, soiling, stool leakage, and stool leakage while passing gas over the past 7 days. Score range is 0-20, where a higher score means increased incontinence.
Time frame: Weeks 0, 4, 8, 12, 24, 38, and 52
Change in Urgency Numeric Rating Scale (NRS)
Urgency will be measured by the 11-point Likert scale urgency question as validated in the mirikizumab clinical trials. Score range is 0-10. The higher the score, the worse the urgency.
Time frame: Weeks 0, 4, 8, 12, 24, 38, and 52
