Summary

This study follows 300 adults with Crohn's disease who are starting standard treatments like vedolizumab or IL-23 blockers. Researchers will track how quickly patients feel improvements in pain, fatigue, and daily functioning using simple questionnaires. The goal is to better understand when these therapies start working, helping guide future treatment decisions.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
vedolizumab, ustekinumab, risankizumab, guselkumab, mirikizumab
What this could lead to
If successful, this study could help doctors predict which Crohn's treatment works fastest for each patient, improving personalized care.
What could go wrong
This is an observational study, not a controlled trial, so it cannot prove cause and effect. Results may not apply to all patients.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Participant is an adult 18 years of age or older with confirmed CD, as per standard clinical criteria which may include symptoms, endoscopy, histopathology, and imaging. 2. Participant has active CD and has been prescribed as standard of care (SOC) and is planned to start VDZ or IL-23 antagonist therapy (UST, RISA, or GUS or MIR \[if approved for the treatment of CD during the recruitment period for this study\]) for the first time in accordance with the product label, as determined by the treating physician. 3. Participant has a baseline PROMIS Pain Interference-SF score ≥ 15 (corresponding T-score ≥ 55) (PROMIS Pain Interference-SF 8a \[V1.1\]). a. Score is calculated by adding score (1 to 5) for each of the 8 subcomponents. 4. Participant has completed all SOC biologic work-up assessments (this may include assessment of tuberculosis, chronic infections, Clostridioides difficile infection and vaccination status per local practice). 5. Ability of participant to participate fully in all aspects of this observational study. Full comprehension of consent language and informed consent must be obtained from the participant and documented. Exclusion Criteria: 1. Participant has CD-related surgery planned or anticipated during the study. 2. Participant has prior exposure to an advanced therapy for the treatment of CD (biologic or small molecule) other than an anti-TNF (i.e., anti-integrin, anti-IL, Janus kinase inhibitors, or sphingosine-1-phosphate receptor 1). Prior failure or intolerance to 2 or more anti-TNF (i.e., infliximab, adalimumab, or certolizumab pegol) therapies in the past 3 years is also cause for exclusion. 3. Participant has an active infection at baseline requiring intravenous systemic antibiotics. Note: The treating physician must have completed all appropriate baseline screening tests as per the product label. 4. Participant has evidence of C. difficile toxin or is prescribed treatment for C. difficile infection, or other intestinal bacterial pathogen, ≤ 2 weeks prior to Screening. 5. Participant has chronic non-inflammatory bowel disease pain.
