Trial Summary

What is the purpose of this trial?

The purpose of this study is being done to determine whether magnetic resonance imaging (MRI) using inhaled hyper-polarized 129 Xenon gas can help visualize impaired lung function to detect changes over time in Idiopathic Pulmonary Fibrosis (IPF) patients receiving approved IPF treatments. Subjects will undergo an approximately hour long comprehensive MRI protocol, including administration of multiple doses of hyper-polarized 129 Xenon. The subjects will have this initial study prior to initiation of IPF therapies. Then the subjects will have repeat studies at 3, 6 and 12 months following the initiation of therapy. Additional studies including pulmonary function studies, serum for bio markers, 6 minute walk distance and a high-resolution computed tomography (HRCT) scan (only at the 6 month visit) will be performed to determine how 129 Xenon MRI performs relative to standard of care evaluations for IPF. The MRI uses a magnet and radio waves to make diagnostic medical images of the body. There have been no ill effects reported from exposure to the magnetism or radio waves used in this test. Risks of the xenon gas are slight numbness in legs, nausea, a feeling of well-being, and mild tingling in fingertips. You will have pulmonary function testing for the study, you may experience breathlessness or dizziness during or immediately following these tests.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but it requires participants to be new to IPF treatments like nintedanib or pirfenidone.

What data supports the effectiveness of the treatment Hyperpolarized 129 Xenon Gas for idiopathic pulmonary fibrosis?

Research shows that Hyperpolarized 129 Xenon MRI can effectively image lung function and detect impaired lung physiology in idiopathic pulmonary fibrosis (IPF). It provides detailed images of how gas moves through the lungs, which can help monitor disease progression and assess treatment response. ^{1 2 3 4 5}

Is hyperpolarized 129 Xenon gas safe for use in humans?

Research shows that hyperpolarized 129 Xenon gas has been used safely in both healthy volunteers and people with lung diseases for MRI imaging. It is considered tolerable and has been studied for its ability to help visualize lung function without significant safety concerns. ^{1 5 6 7 8}

How does Xenon MRI differ from other treatments for idiopathic pulmonary fibrosis?

Xenon MRI is unique because it uses hyperpolarized xenon-129 gas as a contrast agent to provide detailed images of lung function, specifically assessing ventilation and gas transfer, which is not possible with standard imaging techniques. This approach offers a novel way to evaluate lung physiology in patients with idiopathic pulmonary fibrosis, potentially identifying issues that other treatments might miss. ^{1 2 8 9 10}

Findings from Research

Hyperpolarized 129 Xenon-MRI (HP 129 Xe MRI) is a new imaging technique that can assess both how well air moves in and out of the lungs (ventilation) and how effectively gases are transferred in the lungs.

While most studies have focused on non-cancer lung diseases, HP 129 Xe MRI shows great potential for improving the management and understanding of lung cancer by evaluating these key lung functions.

Functional airway obstruction observed with hyperpolarized 129 Xenon-MRI. Song, EJ., Kelsey, CR., Driehuys, B., et al.[2022]

Hyperpolarized xenon-129 MRI detected significant lung function impairments in patients with usual interstitial pneumonia (UIP), showing a ventilation defect fraction of 30% compared to 21% in healthy controls, indicating its efficacy in identifying lung abnormalities.

The MRI also revealed elevated levels of xenon dissolved in the lung interstitium in UIP patients, which could serve as an early indicator of lung fibrosis, even when traditional pulmonary function tests showed normal or mild impairment.

Hyperpolarized 129Xe MRI effectively identifies functional impairment in patients with idiopathic pulmonary fibrosis (IPF), showing a significant increase in barrier uptake compared to healthy individuals, indicating its potential as a diagnostic tool.

The MRI metrics correlated strongly with pulmonary function tests (PFTs) but poorly with CT fibrosis scores, suggesting that 129Xe MRI may provide a more accurate assessment of lung function and disease progression in IPF patients.

Inhalation of hyperpolarized (129)Xe gas was well tolerated among 42 participants, including healthy individuals and those with various pulmonary diseases, with only two mild adverse events reported, indicating a strong safety profile.

The study showed that while there were statistically significant changes in oxygen saturation and heart rate after inhalation, these changes were clinically insignificant and resolved quickly, suggesting that (129)Xe inhalation is safe for use in both healthy and diseased lungs.

A new continuous-flow system for producing hyperpolarized xenon (129Xe) has been developed, achieving production rates of 0.3 liters per hour with 64% polarization, significantly improving the availability of this imaging agent for lung MRI studies.

This technology allows for the production of multiliter quantities of hyperpolarized xenon several times daily, enabling more extensive human lung imaging studies that were previously limited by the availability of hyperpolarized gas.

The study involving 13 healthy volunteers demonstrated that MRI measurements of gas exchange using hyperpolarized 129 Xenon show good repeatability, particularly for the RBC:Barrier ratio, which had a high intraclass correlation coefficient of 0.92.

The RBC:Barrier ratio was strongly correlated with intervisit changes in DLCO, indicating its potential as a reliable imaging biomarker for assessing pulmonary function, independent of lung inflation volume.
