About this study

Official title: The Effect of Airway Clearance Therapy on Hyperpolarized 129Xenon MRI Compared With Lung Clearance Index and Spirometry in Cystic Fibrosis

This is an observational cohort study building on an existing protocol at our institution recruiting CF patients who are 6-21 years old with one or two copies of the F508del CFTR mutation. That existing protocol seeks to enroll a total of 38 subjects; it includes three to four (three scheduled, with a fourth optional) study visits, with spirometry, LCI, UTE MRI, and 129Xe MRI being performed at each visit. This present study will utilize existing study visits for the NHLBI study, with a sub-set of 20 subjects opting-in to have all of the procedures performed twice, with an intervening ACT, during one of their study visits.

Read the detailed description

This is an observational cohort study building on an existing protocol at our institution recruiting CF patients who are 6-21 years old with one or two copies of the F508del CFTR mutation. The existing protocol is funded by the NHLBI under R01-11863962 (PIs Woods, Clancy, and hereafter referred to as "the NHLBI study" for simplicity), and seeks to enroll a total of 38 subjects; it includes three to four (three scheduled, with a fourth optional) study visits, with spirometry, LCI, UTE MRI, and 129Xe MRI being performed at each visit. This present study will utilize existing study visits for the NHLBI study, with patients opting-in to have all of the procedures performed twice, with an intervening ACT, during one their study visits. The target enrollment is 20 subjects.

Airway clearance therapy (ACT) is used for treating cystic fibrosis (CF). It is known to impact measures of lung function, and while an increasing number of lung function measures are used in clinical trials, there has been no direct comparison of the effects of ACT across the different modalities. This study is actively investigating the relationship between different measures of lung function, comparing a spirometric measure (FEV1 percent-predicted) with measures of whole-lung ventilation (lung clearance index, or LCI) and regional assessments of both structure (with ultra-short echo time magnetic resonance imaging, or UTE MRI) and function (with hyperpolarized xenon, or 129Xe, MRI). Performing these assessments on CF patients will help to elucidate the relative sensitivity of each measure to intra-individual changes within the lung and will help guide the selection of lung function measures in future studies.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • hyperpolarized Xenon gasDrug

    Also called 129Xenon

    This present study will utilize existing study visits for the NHLBI study, with patients opting-in to have all of the procedures performed twice, with an intervening ACT, during one their study visits.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Effect of ACT on 129Xe MRI

    Quantify the effect of ACT on 129Xe MRI in ventilation defect percentage (%), in 20 children ages 6-21 years with CF

    Measured: one-day single study visit

Secondary outcomes (2)
  1. Effect of ACT on spirometry

    Quantify the effect of ACT on spirometry in indexed values of FEV1, in percentage (%), in 20 children ages 6-21 years with CF

    Measured: one-day single study visit

  2. Effect of ACT on LCI

    Quantify the effect of ACT on lung clearance index (LCI) in LCI2.5 values, in 20 children ages 6-21 years with CF

    Measured: one-day single study visit

Questions about this trial

What is this clinical trial studying?

An observational study of Cystic Fibrosis, run by Children's Hospital Medical Center, Cincinnati at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 10 Mar 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Effect of ACT on 129Xe MRI (time frame: one-day single study visit). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Mar 2022.
