About this study
Official title: Assessing Pulmonary Changes in Hematopoietic Stem-Cell Transplantation Patients and Patients With Rare-Lung Diseases Using Hyperpolarized Xe MR Lung Imaging
This will be an un-blinded, open-label study of children and adults, including those who are being evaluated for or who have undergone HSCT, those with existing respiratory conditions and/or diagnosed gas-exchange impairment, and healthy control volunteers. The participants will be male or female between 3-17 years old (children) and adults age 18 and older.
The study objective is to:
- To optimize the acquisition of images reflecting the "dissolved-phase" Xe distribution in the pulmonary tissues and blood (Xe gas-exchange MRI).
- To develop and test Xe MRI acquisition strategies that separately image alveolar airspace distribution (ventilation), as well as Xe dissolved in pulmonary tissues versus red blood cells (RBCs).
- To acquire images of Xe ventilation and dissolved-phase Xe regional distribution in the enrolled participants.
- To understand the same-day variability of Xe MRI techniques.
- To determine the relationship between Xe MRI and clinical measures such as pulmonary-function-test (PFT) parameters or other biological biomarkers.
- To develop and optimize strategies for Xe MRI in young children including those who are unable to follow the inhalation and breath-hold instructions typical of the Xe MRI procedure.
- Conditions
- HSCT, Respiratory, Gas Exchange Impairment
- Being tested
- Hyperpolarized 129 Xenon
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Hyperpolarized 129 XenonDrug
Hyperpolarized xenon gas will be administered in doses of up to 1/6TLC (based on either ATS calculations that utilize gender and height to determine the dose or plethysmography data) for participants under 18 years old and 1000 milliliters for adults per our previous research experience followed by a breath hold of up to 16 seconds

What is being measured
The primary outcome is the main question the study is designed to answer.
Xe Gas-Exchange MRI
Images reflecting dissolved-phase xenon distribution in pulmonary tissues and blood obtained by xenon MRI
Measured: Through study completion, an average of 5 years
Secondary outcomes (3)
Establish Aquisition Strategies for Xenon Ventilation Imaging
Ventilation defect percentage (i.e., hypoventilated lung volume) will be analyzed following the xenon MRI
Measured: Through study completion, an average of 5 years
Percentage difference between Xe MRIs repeated within the same-day
Quantitative outcomes from Xe MRI scans, like the ventilation defect percentage (i.e., hypoventilated lung volume), from within the same participant will be compared using paired statistical tests to assess the same-day repeatability.
Measured: Through study completion, an average of 5 years
Correlation between FEV1 and FEV1/FVC from spirometry with ventilation-defect percentage from Xe MRI.
The correlation between FEV1 and FEV1/FVC measured in liters and/or percent predicted from reference equations and the VDP (ventilation defect percentage) from Xe MRI will be determined.
Measured: Through study completion, an average of 5 years

The participants will be male or female between 3-17 years old (children) and adults age 18 and older.
The study objective is to:
- To optimize the acquisition of images reflecting the "dissolved-phase" Xe distribution in the pulmonary tissues and blood (Xe gas-exchange MRI).

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Hyperpolarized 129 Xenon in people with HSCT and Respiratory, 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 1 inclusion and 4 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: looking for participants now, as of the sponsor's last update on 16 Sep 2026. 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.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Ashley Borden, MPH (5136360143, ashley.borden@cchmc.org), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Xe Gas-Exchange MRI (time frame: Through study completion, an average of 5 years). 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 16 Sep 2026.
