Some of the main requirements, copied from the record:
- Body weight >= 10 kilogram (kg)
- Active CD confirmed by endoscopy (ileocolonoscopy)
- Moderately to severely active CD, defined as a Pediatric Crohn's Disease Activity Index (PCDAI) score >= 30, and Simple Endoscopic Score Crohn's Disease (SES-CD) >=6 (or >=4 for isolated ileal disease) confirmed through centrally-read…
- Inadequate response, loss of response, and/or intolerance to at least one of the following conventional therapies (aminosalicylates, corticosteroids and/or immunosuppressants) or advanced therapies (including anti-tumor necrosis factor,…
There are also 6 reasons someone might not be able to join (exclusion criteria). Only the trial team can confirm whether you qualify.
