129Xe Gas Exchange Imaging in IPF and cHP: A Reliability Study

Study Purpose

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.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Yes
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

More Inclusion & Exclusion Criteria

Inclusion Criteria:

  • - Adults > 18 years of age - Diagnosis of progressive chronic HP, IPF as determined by MDD discussion (historical or during screening period) OR normal control (no history of known lung disease, no abnormal parenchymal or airway findings on CT examination and no values outside of the normal for FVC, FEV1, TLC, and DLCO.
)
  • - FVC % Predicted >45% - DLCO % Predicted >30% - Progressive lung disease as defined by one of the following criteria within 24 months of screening visit - Relative decline in the FVC ≥ 10% of the predicted value - Relative decline in the FVC of ≥ 5% - < 10% of the predicted value and worsening of respiratory symptoms - Relative decline in the FVC of ≥ 5% - < 10% of the predicted value and an increased extent of fibrosis on prior clinical high-resolution CT - Worsening of respiratory symptoms and an increased extent of fibrosis on high-resolution CT.

Exclusion Criteria:

- Stable FVC over 2-year period as determined by study physician - Unstable cardiac condition within 6 months of screening as determined by study physician

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT04677426
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Arms & Interventions

Arms

Experimental: Subjects with Progressive Interstitial Lung Disease

Assess the intra-visit reliability and sensitivity to progression of 129Xe MR imaging measurements using a standardized imaging protocol in subjects with IPF and cHP.

Interventions

Drug: - Hyperpolarized Xe129

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.
