ClinicalTrials.gov ID: NCT06456593

What this study is testing

What is Obefazimod?

Obefazimod is an investigational oral medicine being studied for the treatment of moderately to severely active Crohn disease.

Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
The study wants to see if obefazimod works and is safe compared to a placebo during induction and maintenance periods. In the final 48‑week part, it will look mainly at safety and how well patients tolerate the drug.
Who it's for
It is looking for adults with moderately to severely active Crohn’s disease who did not get enough benefit from standard or advanced therapies.
What's involved
Participants will receive either obefazimod or a placebo. They will have regular clinic visits, blood tests, and other safety checks throughout the study phases.
Time commitment
The study lasts up to 48 weeks, with visits during the 12‑week induction, 40‑week maintenance, and 48‑week extension periods. Participants will need to attend scheduled appointments during each phase.
  • Phase 2: a mid-size study of how well it works
  • You might receive a placebo (an inactive treatment) instead of the study drug.
