New antibody aims to calm ulcerative colitis when other treatments fail

NCT ID NCT04882007

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This phase 2 trial tests whether OSE-127, an antibody that blocks a key immune signal, can reduce disease activity in people with moderate to severe ulcerative colitis who have not responded to or cannot tolerate previous treatments. Participants are randomly assigned to receive either OSE-127 or a placebo, and neither they nor their doctors know which they receive. The main goal is to see if the drug improves a combined score of symptoms and endoscopic findings after 10 weeks.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

OSE-127 (a monoclonal antibody that blocks the IL-7 receptor)

What this could lead to

If successful, OSE-127 could offer a new treatment option for people with ulcerative colitis who have not been helped by existing therapies.

What could go wrong

This is an early phase 2 study with a small number of participants, so results may not apply to everyone. The drug may not work better than placebo or could cause unexpected side effects.
