Canada86 participantsStarted 2020-10-20

Plain-language summary

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.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
