Can early symptom relief predict who stays on IBD biologic?
NCT ID NCT07822529
First seen Sep 16, 2026 · Last updated Sep 17, 2026 · Updated 1 time
Summary
Researchers are tracking how long adults with moderate to severe Crohn's disease or ulcerative colitis keep taking guselkumab, a biologic drug, in routine care. The study follows about 400 people who start the treatment and records when they stop. It also checks whether early improvements in bowel urgency and other symptoms relate to staying on the drug. The goal is to understand real-world persistence with this treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- guselkumab, a biologic drug given for inflammatory bowel disease
- What this could lead to
- If the drug keeps working well over time, this could help doctors understand which patients with Crohn's disease or ulcerative colitis benefit most from staying on guselkumab.
- What could go wrong
- This is an observational study, so it cannot prove the drug causes any outcome. People may stop treatment for many reasons unrelated to how well it works, and the results may not apply to everyone with these conditions.

Inclusion criteria: * Must be greater than or equal to (\>=) 18 years old * Must be eligible for biologic treatment and initiate guselkumab according to the approved indications as described in the current version of the summary of product characteristics (SmPC) of the drug. Decision to prescribe must solely be made by the treating physician. Enrolment must take place before or on the day of the first administration (but after treatment decision by physician) * Must have a confirmed diagnosis of moderate-to-severe Crohn's disease (CD) or Ulcerative Colitis (UC) recorded in their medical records * Participant has received the information note/given his/her oral agreement and has not objected to the collection of their data Exclusion criteria: * Contraindicated to guselkumab per the label * Is currently enrolled in an interventional clinical study * Has been previously exposed to interleukin (IL)-23 inhibitors, including Tremfya (guselkumab), Skyrizi (risankizumab) and Omvoh (mirikizumab). As an exception, participants with a prior history of Stelara (ustekinumab) and biosimilars exposure, may be included * History of more than 4 lines of advanced inflammatory bowel disease (IBD) therapy (biologics and/or small molecules)
