Vurdering af CFTR-modulatorbehandling ved lungesygdom med cystisk fibrose ved hjælp af ny strukturel og funktionel MR

5. november 2026 opdateret af: Giles Santyr, The Hospital for Sick Children

This is a prospective, longitudinal observational study conducted at The Hospital for Sick Children (SickKids). The purpose of this study is to evaluate the ability of MRI to detect changes in lung structure and function in CF patients receiving CFTR-modulator therapy. Participants who meet eligibility criteria and consent to the study will undergo study procedures which include spirometry and body plethysmography (optional), multiple breath washout testing, MRI and measurement of quality of life. The study will consist of three to six study visits for Group 1, 2 and 3: baseline, one month (±1 week) and 6 month (±2 week) and if they re-consent then 3 additional visits of 1 year (±6 months). (2 years (±6 months) and 3 years (±6 months) follow-up. Some participants in Group 2 may transition to Group 3.

This study includes three populations of interest: Group 1: 25 healthy volunteers, Group 2: 25 patients with stable CF lung disease , Group 3: 20 patients with CF lung disease anticipated to receive treatment with CFTR-modulator therapy and Group 4: 18 patients with CF who are between 4-8 years old and are starting triple combination modulator therapy using the rapid lung and abdominal imaging methods.

Kohorter og interventioner

Gruppe / kohorte
Group 1

Healthy participants without lung disease

Group 2

Participants with stable cystic fibrosis

Group 3

Participants with cystic fibrosis, anticipated to receive treatment with CFTR-modulator therapy. Please note: treatment is determined by your physician as part of your normal therapy plan.

Foranstaltningsbeskrivelse
Tidsramme
Reproducibility
Tidsramme: 36 months

Establish the interscan reproducibility of fractional ventilation maps and 1H MRI over three and up to six visits in healthy volunteers and in patients with stable CF lung disease and compare to conventional spirometry and LCI.

36 months
Correlation
Tidsramme: 12 months

Correlate changes in lung structure and function detected by MRI imaging with clinical outcomes including FEV1 rate of decline, frequency of pulmonary exacerbations, days of IV antibiotics and hospital days to treat pulmonary exacerbation and change in health-related quality of life measures (CFQ-R scores and CF-QUEST) in the setting of patients with stable CF lung disease and those receiving CFTR-modulator therapy.

12 months
Responsiveness
Tidsramme: 36 months

Assess responsiveness of MRI to treatment effects over three and up to six visits visits in CF patients receiving CFTR-modulator therapy and compare to conventional breathing tests

36 months
Younger cohort
Tidsramme: 24 months

Extension of above objectives originally only explored in children ages 8-18 years old, to younger cohort of CF participants ages 4-8 years old at baseline prior to initiation of CFTR modulator therapy, as well as at 12 and 24 months after therapy initiation.
