Mirikizumab Administered at the Same Time as Tirzepatide in Adult Participants With Moderately to Severely Active Ulcerative Colitis and Obesity or Overweight: Phase 3b Study
(COMMIT-UC)
What this study is about
The main purpose of this study is to show whether in these individuals, treatment with both mirikizumab and tirzepatide, compared with treatment with mirikizumab and placebo, leads to decrease or disappearance of UC symptoms, and loss of at least one-tenth of the overall body weight. Participation in this study will last up to 61 weeks, including 52 weeks of treatment.

Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Have had an established diagnosis of UC for ≥3 months before baseline which includes endoscopic evidence of UC and a histopathology report that supports a diagnosis of UC.
- Have moderately to severely active UC as defined by a modified Mayo score (mMS) of 5 to 9 points and endoscopic subscore (ES) of 2 to 3 (confirmed by central review) within 21 days before baseline.
- Participants with a history of UC for greater than or equal to 8 years who have had a surveillance colonoscopy completed within 1 year prior to baseline must have documented negative results for colorectal dysplasia and cancer.
- Have obesity, \[body mass index (BMI) 30 kilograms per meter squared (kg/m2)\]
- Have overweight (BMI ≥27 kg/m2 to \<30 kg/m2) and in the presence of at least 1 of these weight-related comorbid conditions:
- hypertension
- Type 2 Diabetes Mellitus (T2DM)
- dyslipidemia
- obstructive sleep apnea, or
- cardiovascular disease.
- Have an inadequate response to, loss of response to, or intolerance to at least 1 of the conventional medication: oral corticosteroids, oral azathioprine (AZA) or 6-mercaptopurine (6-MP), or oral 5-aminosalicylates (for example, mesalamine, sulfasalazine, olsalazine, and balsalazide) and/or who have an inadequate response to or a loss of response to, or are intolerant to advanced therapy for UC, defined as: a biologic or biosimilar medication such as anti-tumor necrosis factor (TNF) antibodies; anti-integrin antibodies, Janus kinase (JAK) inhibitors such as tofacitinib or upadacitinib, sphingosine 1-phosphate receptor 1inhibitors such as etrasimod or ozanimod, or anti-interleukin(IL)-12p40 antibodies, for example, ustekinumab.
Exclusion criteria
- Have a current diagnosis of:
- Crohn's disease
- inflammatory bowel disease (IBD) unclassified (formerly known as indeterminate colitis), or
- primary sclerosing cholangitis.
- Have had or will need bowel resection or intestinal or intra-abdominal surgery.
- Have evidence of toxic megacolon, or stricture or stenosis within the colon that cannot be traversed by a sigmoidoscope or colonoscope.
- Have a diagnosis of Type 1 Diabetes Mellitus (T1DM) or have insulin-treated T2DM.
- Have a history of severe hypoglycemia and/or hypoglycemia unawareness within the 6 months prior to screening.
- Have a self-reported change in body weight greater than 5% (gain or reduction) within 3 months prior to screening.
- Have a current or recent acute, active infection.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
