New drug combo shows promise for stubborn ulcerative colitis
NCT ID NCT03123120
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This phase 2 study tested whether adding spesolimab to standard TNF inhibitor therapy could help heal the gut lining in people with mild-to-moderate ulcerative colitis. Twenty-two adults who still had active disease despite TNF inhibitor treatment received spesolimab or a placebo for 12 weeks. The main goal was to see if the drug could improve endoscopic signs of inflammation.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Spesolimab (a monoclonal antibody that blocks a protein called IL-36 receptor, given as an injection)
- What this could lead to
- If it works, this could offer a new add-on option to help heal the gut lining in people with ulcerative colitis who still have symptoms despite TNF inhibitor therapy.
- What could go wrong
- This was a very small, early proof-of-concept study with only 22 participants. Results may not apply to everyone, and the drug may not prove effective or safe in larger trials.
