What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores a new type of lung scan, called HP 129Xe MRI, to help doctors identify and predict side effects from radiation therapy in lung cancer patients. Unlike traditional MRI scans, this one uses an inhaled tracer instead of an injection. The trial seeks healthy individuals who can hold their breath for 10-12 seconds and those with a confirmed lung cancer diagnosis undergoing radiation treatment. Participants must travel to the University of Texas MD Anderson Cancer Center for follow-ups. As an Early Phase 1 trial, this research aims to understand how this innovative scan functions in people, offering participants a chance to contribute to groundbreaking advancements in lung cancer care.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the study team or your doctor.

What prior data suggests that this HP 129Xe MRI is safe for use in humans?

Research has shown that HP 129Xe MRI, which uses a special gas for imaging, has been used to study lung problems. In these studies, participants inhaled the gas, which helped reveal lung function. So far, this method appears safe, with no major issues reported.

As this study is in the early stages, researchers are primarily focused on assessing the treatment's safety. Although the 129Xe tracer lacks FDA approval, earlier studies suggest it does not cause serious side effects. Participants can feel reassured knowing that safety remains a top priority in these trials. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about HP 129Xe MRI because it offers a new way to visualize lung function in patients with lung cancer. Unlike traditional imaging methods such as CT or PET scans, this technique uses hyperpolarized xenon gas, which patients inhale. This approach allows for a non-invasive, detailed look at how air moves through the lungs and how well gases are exchanged. It's especially promising because it could help doctors better understand and track lung health without exposing patients to radiation. This could lead to earlier detection of changes in lung function, potentially improving treatment planning and outcomes.

What evidence suggests that HP 129Xe MRI is effective for identifying and predicting side effects of radiation therapy?

Research has shown that HP 129Xe MRI is a promising method for assessing lung function. It allows doctors to evaluate how air moves and exchanges in the lungs. Studies have found that this technique can track changes in lung function after radiation therapy. This method is highly sensitive and can detect small changes in lung structure and function. In this trial, participants will be divided into different groups, including high-risk and low-risk RP patients, as well as healthy volunteers. Although still under investigation, HP 129Xe MRI might help identify and predict common side effects of radiation therapy in lung cancer patients. ^{4 6 7 8 9}
