Is this trial a fit for you?

Likely a good fit

Children and adolescents aged 5–18 years with a confirmed inflammatory bowel disease, not on probiotic therapy for four weeks prior, and able to follow study procedures.

Probably not a fit

Patients with severe active disease or contraindications to probiotics or study procedures may experience no benefit.

What this trial studies

This study examines how a probiotic formula affects the intestinal microbiome and metabolic profiles in pediatric patients with inflammatory bowel disease. Participants are 5 to 18 years old and will receive probiotic therapy with observational monitoring. The trial uses predefined inclusion and exclusion criteria to select suitable candidates and will compare microbiome changes during intervention, with safety and feasibility endpoints in a real-world clinical setting. Data from Inselspital Bern and affiliated centers will inform potential microbiome-driven approaches to disease management.

Why it matters

Potential benefit: If successful, the probiotic intervention could reveal microbiome changes associated with disease modulation and guide future personalized therapy for pediatric IBD.

How similar studies have gone: Previous work in probiotics and pediatric IBD has shown microbiome-related signals, but results vary and this study explores a multi-strain formulation specifically.
