What this trial is testing
This study is testing Guselkumab (GUS) (a drug) as a possible treatment. Condition(s) listed: Crohn Disease.
It is open-label: participants know what they are receiving.
Phase 4 studies look at treatments that are already approved, to learn more about how they work in everyday use.
Who can join
- Ages 18 and older
- Any sex
Some of the main requirements, copied from the record:
- Has a confirmed diagnosis of Crohn's disease (CD)
- Diagnosed with active CD, as defined by baseline Crohn's Disease Activity Index (CDAI) score greater than or equal to (>=) 220
- Participants had received the ustekinumab (UST) induction phase and received maintenance therapy via subcutaneous (SC) injection every 8 weeks or every 12 weeks
- Initially responded to UST induction therapy and then lose response to UST
- During the screening period, participants are receiving UST treatment as the first line biologic or second line biologic
There are also 5 reasons someone might not be able to join (exclusion criteria). Only the trial team can confirm whether you qualify.

- Percentage of Participants Achieving Clinical Remission At Week 48 (At Week 48)
In the researchers’ words
The purpose of this study is to evaluate how well guselkumab works in participants with Crohn's disease (CD; a long-term condition causing severe inflammation of the intestinal tract) who no longer respond to treatment with ustekinumab.
