What this trial studies

This study aims to evaluate the effects of probiotic supplementation on gastrointestinal (GI) related quality of life in pediatric patients with cystic fibrosis (CF) through a randomized placebo-controlled trial. It includes two work packages: one observational and one interventional, where participants will be randomized to receive either probiotics or a placebo. The study will also explore the gut microbiota and intestinal inflammation in relation to a new CF treatment, elexacaftor-tezacaftor-ivacaftor (ETI). By assessing these factors, the study seeks to enhance the overall care and management of children with CF.

Who should consider this trial

Good fit: Ideal candidates are pediatric patients aged 2-18 years with cystic fibrosis who are eligible for treatment with ETI.

Not a fit: Patients currently experiencing a pulmonary exacerbation or those who have recently used other CFTR modulators or probiotics may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly improve the quality of life and reduce gastrointestinal issues in children with cystic fibrosis.

How similar studies have performed: Other studies have shown promising results with probiotic supplementation in similar patient populations, suggesting potential for success in this approach.
