What this trial studies

This observational cohort study aims to evaluate the effectiveness and safety of CFTR modulators in children under 18 years with cystic fibrosis. It focuses on monitoring pulmonary structural impairment using low-dose CT scans at the end of the first year of treatment, as well as at 3 and 5 years. Secondary objectives include assessing respiratory function, growth, quality of life, and potential side effects of the treatment. The study is conducted as part of routine care, emphasizing the need for sensitive outcome measures in this pediatric population.

Who should consider this trial

Good fit: Ideal candidates are children under 18 years old diagnosed with cystic fibrosis who are currently undergoing CFTR modulator therapy.

Not a fit: Patients over the age of 18 or those without an indication for CFTR modulator therapy will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved management and outcomes for children with cystic fibrosis receiving CFTR modulators.

How similar studies have performed: While CFTR modulators have been studied in adults, this specific focus on pediatric patients and the use of low-dose CT scans for monitoring is a novel approach.
