About this study

This research is a study to test the reliability of Hyperpolarized Xenon MRI (HXe MRI) as a biomarker in interstitial lung disease. The study is a non-randomized study to evaluate the test-retest performance of HXe MRI in Idiopathic Pulmonary Fibrosis (IPF) and chronic Hypersensitivity Pneumonitis (cHP) as a non-invasive biomarker of disease severity and prognosis. The study will include approximately 15 subjects with IPF, 15 subjects with cHP and 10 sex and age-matched normal controls performed across 3 sites.

Being tested
Hyperpolarized Xe129
Medical subject headings
Idiopathic Pulmonary Fibrosis, Alveolitis, Extrinsic Allergic

What participants receive

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

  • Hyperpolarized Xe129Drug

    Also called Xenon, HP 129Xe

    Whether magnetic resonance imaging (MRI) using inhaled hyper-polarized 129 Xenon gas can help visualize impaired lung function to assess patients with cHP and IPF.

Study groups in NCT04677426
Study groupRoleWhat they receive
Subjects with Progressive Interstitial Lung DiseaseExperimentalAssess the intra-visit reliability and sensitivity to progression of 129Xe MR imaging measurements using a standardized imaging protocol in subjects with IPF and cHP.
Receives: Drug: Hyperpolarized Xe129

What is being measured

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

  1. RBC:Barrier Ratio

    RBC:Barrier ratio will be determined using 129 Xenon MRI in 2 successive scans on two separate days 6 months apart. Same-day Repeated measures will be used to assess reliability of RBC:Barrier. Data acquired at 6 months will be correlated with FVC.

    Measured: RBC:Barrier will be assessed at Baseline and at 6 months.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Hyperpolarized Xe129 in people with Idiopathic Pulmonary Fibrosis and Hypersensitivity Pneumonitis, run by University of Kansas Medical Center.

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 9 inclusion and 2 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The record says: withdrawn, as of the sponsor's last update on 10 Sep 2022. Status can change between updates, so confirm with the study contact before making plans.

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 phase mean?

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?

The study was withdrawn before enrolling participants, so there are no results.

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?

RBC:Barrier Ratio (time frame: RBC:Barrier will be assessed at Baseline and at 6 months.). 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 Sep 2022.
