Exploring the Utility of Hyperpolarized 129Xe MRI in Healthy Volunteers and Patients With Lung Disease
Study Purpose
This is a single centre exploratory study that aims to apply hyperpolarized xenon-129 (129Xe)
magnetic resonance imaging (MRI) methods and measurements in individual patients with and
without lung disease to better understand lung structure and function and evaluate response
to therapy delivered as a part of clinical care.
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.

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.
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.

Conditions
The disease, disorder, syndrome, illness, or injury that is being studied.
The primary objective of this study is to evaluate the ventilation defect percent (VDP),
apparent diffusion coefficient (ADC) and/or the signal-to-noise ratio (SNR) obtained by
analysis of hyperpolarized 129Xe MRI at one or more time-points (over time in the absence of
therapeutic intervention or following clinically indicated therapy) in healthy volunteers and
patients with lung disease including but not limited to: asthma, emphysema, COPD,
bronchiectasis, sarcoidosis, pulmonary fibrosis, alpha 1-anti-trypsin deficiency,
eosinophilic granulomatosis with polyangiitis and bronchopulmonary dysplasia.
This will be a single centre exploratory study in 10 healthy volunteers with normal lung
function and no history of lung disease and 50 patients with a clinical diagnosis of lung
disease. There is one study visit required for participation. A subset of participants may be
asked to return for up to five additional study visits per year for five years. The purpose
of additional study visits is to understand how hyperpolarized 129Xe MRI measurements of lung
structure and function change over time in the absence of therapeutic intervention or
following clinically indicated therapy.
All subjects will visit St Joseph's Healthcare Hamilton and undergo: vital signs, pulmonary
function testing, questionnaires, proton (1H) MRI, static ventilation and/or
diffusion-weighted 129Xe MRI, and sputum induction. Up to four doses of hyperpolarized 129Xe
will be inhaled during a single study visit.
Arms & Interventions
Arms
Experimental: Patients with and without lung disease
All enrolled patients will undergo pulmonary function testing, questionnaires, 1H MRI, static ventilation and/or diffusion-weighted hyperpolarized 129Xe MRI and sputum induction at one or more timepoints over five years.
Interventions
Other: - Hyperpolarized 129Xe MRI
Magnetic resonance imaging (MRI) using inhaled hyperpolarized 129Xe gas is a research approach for the non-invasive visualization and measurement of lung structure and function.
