About this study
In plain language
This study tests diet and tirzepatide (Zepbound) shots as added treatments for Crohn’s disease. It is for adults with mild Crohn’s disease, a body mass index (BMI) of at least 27, and stable doses of infliximab or adalimumab.
The purpose of this study is to use diet and an injectable medication called tirzepatide (Zepbound) glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1 receptor agonist (GIP-GLP-1 RA) medication as adjunctive therapy (another treatment used together with the primary treatment) for Crohn's disease patients with mild disease who are on stable doses of biologic medication (infliximab or adalimumab) and who have a body mass index (BMI) of at least 27.
Compensation is read from the study's own description and may be missing — always confirm with the study team.
Eligibility
Who can join
- Age 18 or older.
- Have a confirmed diagnosis of Crohn’s disease.
- Have mildly active disease, with a symptom score called the Harvey Bradshaw Index (HBI) between 5 and 7.
- Have a BMI of 27 or higher. BMI is a measure based on height and weight.
- Take stable doses of anti-TNF medicines, such as infliximab or adalimumab, which reduce inflammation.
Who can't join
- Under age 18 or have a BMI below 27.
- Have ulcerative colitis or colitis caused by an infection. Colitis means swelling and irritation in the colon.
- Have type 1 or type 2 diabetes.
- Cannot safely take GIP/GLP-1 medicines, including because of a personal or family history of medullary thyroid cancer, or multiple endocrine neoplasia type 2 (a condition affecting hormone-making glands).
- Already take a GIP/GLP-1 medicine.
- Have long-term severe constipation, nausea, or vomiting.
- Had a blockage in the small intestine in the past year, have a narrowed intestine, or have known or suspected gastroparesis (slow stomach emptying).
- Cannot consent to join, are pregnant (checked with a pregnancy test), or are a prisoner.
