What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests a special MRI technique that uses inhaled gas to create detailed images of lung function in people with cystic fibrosis. Researchers want to see how a new triple-combination therapy changes lung ventilation over time. The study involves 64 participants and aims to find better ways to measure treatment success, especially in early-stage disease.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
CFTR modulator (triple combination therapy) and inhaled hyperpolarized 129Xe contrast for MRI
What this could lead to
If successful, this could help doctors use MRI to detect early lung changes in cystic fibrosis, guiding better and more personalized treatments.
What could go wrong
This is a small, early-phase study focused on imaging, not on proving the therapy works. The results may not apply to all patients or lead to immediate new treatments.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Written informed consent (and assent when applicable) obtained from subject or subject's legal representative. 2. Willingness and ability to adhere to the study visit schedule and other protocol requirements. 3. Documentation of a CF diagnosis as evidenced by one or more clinical features consistent with the CF phenotype and one or more of the following criteria: 1. Sweat chloride equal to or greater than 60 mEq/liter by quantitative pilocarpine iontophoresis test 2. Two well-characterized mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene 4. Phase 1 only: Age 6 to 18 years, inclusive, at the time of consent. 5. Phase 2 only: Ages 9 to 18 years, inclusive, at the time of consent. 6. Clinically stable with no acute antibiotic usage in the 14 days prior to the first visit. 7. Genotype with F508del on at least one allele. 8. No change in chronic pulmonary medications or therapies in the 28 days prior to the first visit. 9. Stable CFTR modulator therapy (TEZ/IVA or LUM/IVA) for at least 28 days prior to the first visit or currently not receiving CFTR modulator therapy. 10. Ability to cooperate with MRI procedures. 11. Phase 1 only: FEV1 greater than or equal to 80% predicted based on GLI reference equations. Exclusion Criteria: 1. Standard MRI exclusions (Metal implants, claustrophobia). 2. For females of childbearing potential: Positive urine pregnancy test at Screening or Visit 1 or Lactating. 3. Any other condition that, in the opinion of the Site Investigator/designee, would preclude informed consent or assent, make study participation unsafe, complicate interpretation of study outcome data, or otherwise interfere with achieving the study objectives.
