Tirzepatide to heal small-bowel Crohn's disease after failure of advanced therapies
Official title: Moving Beyond Inflammation as a Therapeutic Target for Crohn's Disease
Run by Washington University School of Medicine · NCT06976853 · Data updated 2026-11-12
This trial will test whether tirzepatide can help heal ileal or ileocolonic Crohn's disease in adults whose inflammation has not responded to at least two advanced treatments.

Is this trial a fit for you?
✓Likely a good fit
Adults 18–80 with confirmed Crohn's disease involving the ileum or ileocolon, active endoscopic inflammation (Ileal SES-CD >4 and ulcer subscore >1), and documented failure of at least two advanced-class drugs are the intended participants.
✕Probably not a fit
Patients whose disease is well controlled on current therapy, whose inflammation is limited to the colon rather than the small bowel, pregnant women, or those with contraindications to tirzepatide are unlikely to benefit from participation.

What this trial studies
This Phase 2 interventional trial enrolls adults with confirmed Crohn's disease and active ileal or ileocolonic inflammation despite prior treatment with at least two advanced-class drugs. Eligible participants receive tirzepatide alongside standard-of-care monitoring and undergo symptom questionnaires, colonoscopic assessment of the ileum, and collection of blood, stool, and intestinal biopsy samples. Endoscopic healing (using SES-CD scoring) and biological markers from tissue, blood, and stool will be used to measure treatment effect and explore mechanisms. The study is conducted at three U.S. academic centers with periodic clinical visits and at least one colonoscopy to document intestinal healing.
Why it matters
Potential benefit: If successful, tirzepatide could promote healing of affected small-bowel segments and offer a new option for patients who have not responded to multiple advanced therapies.
How similar studies have gone: This approach is relatively novel for Crohn's disease: tirzepatide has demonstrated metabolic and weight-loss benefits in diabetes and obesity studies but has not been widely tested for healing small-bowel Crohn's inflammation.

Inclusion Criteria: 1. Subjects 18 to 80 years of age, inclusive, at the time of consent 2. Confirmed diagnosis of Crohn's disease based on documented findings on endoscopy and histopathology 3.

Failure to respond to (primary or secondary non-response) at least 2 advanced class drugs, without evidence of immunogenicity (anti-TNFa only). Must have been at least 6 months optimized on most recent therapy without corticosteroids. 1. Anti-TNF: Infliximab, Adalimumab, Certolizumab, Golimumab 2. Anti-integrin agent: vedolizumab 3. Anti-IL12/23 agent: Ustekinumab 4. Anti-IL23: Risankizumab, Guselkumab, Mirikizumab 5. JAK inhibitor: Upadacitinib 5. In post surgical patients, must be at least 6 months post-op with endoscopic evidence of ileal disease 6. In females: compliance to recommended birth control requirements Exclusion Criteria: 1. Age \< 18 or \> 80 years 2. Pregnant or Breastfeeding female 3. Diagnosis of ulcerative colitis, indeterminate colitis, microscopic colitis, ischemic colitis, radiation colitis, diverticular disease-associated colitis, toxic megacolon, active infectious colitis or positive test for Clostridioides Difficile toxin at screening 4. BMI \< 25 5. Current or previous diagnosis of anorexia nervosa 6. Type 1 or Type 2 diabetes 7. Use of concomitant hypoglycemic agents 8. Personal or family history of medullary thyroid carcinoma 9. History of multiple endocrine neoplasia 10. Known serious hypersensitivity to tirzepatide or any of its excipients 11. Have functional or post-operative short-bowel syndrome 12. Had intestinal resection ≤ 24 weeks prior to inclusion or other intra-abdominal surgeries ≤ 12 weeks prior to study inclusion 13. Active treatment with steroids\* 14. Positive stool test for parasites, C. Diff or stool culture for pathologic bacteria within 30 days prior to enrollment 15. Current stricture not passable with an endoscope 16. Impending need for surgery per investigator 17. Have an ileostomy or a colostomy 18. In females: refusal to comply to recommended birth control requirements \*Corticosteroids have metabolic and hormonal effects which we are concerned may interfere with study outcomes and metabolic changes in the population. This exclusion criteria will allow the study population to be standardized across all patients
