Personalized Risk Estimation for Crohn's Disease (PRE-Crohn's): Implementation and Feasibility

Not applicable Interventional Massachusetts General Hospital · NCT05332639

This project will test a web-based personalized risk tool to see if giving unaffected first-degree relatives of people with Crohn's disease tailored risk information changes their behaviors and early disease markers.

What this trial studies

Unaffected first-degree relatives of patients with inflammatory bowel disease will use a web-based Personalized Risk Estimation for Crohn's Disease (PRE-Crohn's) tool or receive standard Crohn's disease education. The study will compare changes in behaviors linked to Crohn's risk and pre-clinical biomarkers between the two groups over the study period. Participants must be older than 14, able to consent and complete questionnaires, and have no current diagnosis or clinical signs of IBD. The project will measure whether personalized risk disclosure is feasible and whether it leads to measurable biological or behavioral changes that could inform prevention strategies.

Who should consider this trial

Good fit: Unaffected first-degree relatives of people with IBD who are older than 14, can give informed consent, and can complete study visits and questionnaires are ideal candidates.

Not a fit: People who already have a diagnosis of IBD, those with current IBD signs or symptoms, or individuals unable to use the web tool or attend study visits are unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, the tool could help high-risk relatives adopt healthier behaviors and normalize early biomarkers, potentially reducing the chance of developing Crohn's disease.

How similar studies have performed: Personalized risk-disclosure tools have shown mixed success in changing behavior in other conditions, but this approach is relatively novel and untested specifically for Crohn's disease.
