Official title: A Phase 2a, Two-Part, Open-Label and Randomized Study to Evaluate the Safety and Efficacy of OD-07656 and of Subsequent Vedolizumab Therapy in Patients With Moderately to Severely Active Ulcerative Colitis
Run by Odyssey Therapeutics, Inc. · NCT06850727 · Data updated 2026-11-12
This test tries OD-07656, followed by vedolizumab, to see if it improves symptoms in people with moderate to severe ulcerative colitis who have not responded well to other treatments.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults with confirmed moderate to severe ulcerative colitis by the 3-component Modified Mayo score who have had inadequate response, loss of response, or intolerance to at least one prior UC therapy.
✕Probably not a fit
People with Crohn's disease or indeterminate colitis, those who have had extensive colonic resection or an ostomy, or those with uncontrolled primary sclerosing cholangitis are excluded and likely would not benefit.

What this trial studies
This Phase 2 interventional trial gives participants with moderately to severely active ulcerative colitis OD-07656 and monitors safety and clinical outcomes using measures such as the 3-component Modified Mayo clinic score. Eligible participants are those with inadequate response, loss of response, or intolerance to prior therapies including aminosalicylates, corticosteroids, immunosuppressants, biologics, JAK inhibitors, or S1P modulators. A key objective is to determine whether OD-07656 can enhance the therapeutic benefit of vedolizumab when vedolizumab is administered after OD-07656. Study visits will take place at Australian sites including Sunshine Coast University (Birtinya), Eastern Health (Box Hill), and Coastal Digestive Health (Maroochydore).
Why it matters
Potential benefit: If successful, this approach could help more people achieve symptom control or remission, especially those who have not benefited from existing treatments.
How similar studies have gone: Vedolizumab is an established treatment for UC, but OD-07656 is experimental and using it to boost subsequent vedolizumab response is a novel approach with limited prior data.
