About this study

Official title: Bronchopulmonary Dysplasia: From Neonatal Chronic Lung Disease to Early Onset Adult Chronic Obstructive Pulmonary Disease

The investigators will apply xenon-129 (129Xe) and non-contrast enhanced magnetic resonance imaging (MRI) acquisition and analysis methods in 50 subjects aged between 20 and 29 years born pre-term (with and without a diagnosis of bronchopulmonary dysplasia [BPD]) and at term to characterize and probe the relationship between lung structure and function using imaging.

Read the detailed description

This is a pilot, cross-sectional exploratory study to evaluate the relationship between imaging and other biomarkers in fifty patients born pre-term (with or without bronchopulmonary dysplasia [BPD]) and age-matched healthy controls. The term-born adults will serve as the controls.

All subjects will visit the Clinical Imaging Research Laboratories at Robarts Research Institute or the University of Montreal University Health Centre Sainte-Justine in a single visit and undergo: vital signs, pulmonary function testing (more specifically: spirometry, body plethysmography, airwave oscillation, and lung clearance index), questionnaires, proton and 129Xe MRI. Preterm patients will also have a low-dose chest computed tomography (CT), and have blood and urine samples taken for biomarkers of inflammation and oxidative stress.

MRI of the lungs will be performed using non-contrast enhanced methods (ultra-short echo time [UTE] MRI) and using an inhaled contrast agent: Hyperpolarized Xenon-129. Participants will inhale the hyperpolarized gas and perform a breathhold for up to 16 seconds. Four different types of images will be acquired in the coronal plain during each visit: 1) 1H thoracic cavity, 2) 129Xe static ventilation, 3) 129Xe diffusion weighted imaging, and, 4) multi-volume UTE MRI. Respiration and oxygen saturation will be monitored throughout the imaging session.

What participants receive

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

  • Hyperpolarized Xenon-129Other

    Hyperpolarized Xenon-129. Noble gas magnetic resonance imaging (MRI) has recently emerged as another research approach for the non-invasive measurement of lung structure and function, including conduction of gas through airways and into airspaces.

    Noble gas MRI provides a complimentary and alternative method for evaluating lung disease and may be superior to CT because it allows simultaneous visualization of both airway and airspace structure and function.

Study groupRoleWhat they receive
Preterm AdultsExperimentalAll enrolled preterm adults will undergo non-contrast enhanced MRI (using ultra-short echo time methods), hyperpolarized noble gas MRI (using hyperpolarized xenon-129), x-ray computed tomography (CT), pulmonary function tests, and questionnaires in a single visit.

What is being measured

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

  1. Number of patients with MRI-derived tissue signal intensity less than normal for age-matched individuals without BPD

    This will be measured using non-contrast enhanced MRI methods (ultra-short echo time MRI) and hyperpolarized noble gas MRI methods. Mean whole lung signal intensity measurements will be quantified after the UTE MRI acquisition. Ventilation defect percent and apparent diffusion coefficients will be determined after noble gas MR acquisition.

    Measured: Baseline

Secondary outcomes (2)
  1. Forced Expiratory Volume in 1 s (FEV1) measured using spirometry

    Measured: Baseline

  2. Number of patients with abnormal Pulmonary Function measurement of surface-to volume ratio for gas exchange

    diffusing capacity of carbon monoxide (DLCO) as a percent of predicted value for normal subjects of the same age and size

    Measured: Baseline

Questions about this trial

What is this clinical trial studying?

A study testing Hyperpolarized Xenon-129 in people with Bronchopulmonary Dysplasia and Preterm Birth, run by Western University, Canada at 1 site in Canada.

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 5 inclusion and 5 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: finished, as of the sponsor's last update on 12 May 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Number of patients with MRI-derived tissue signal intensity less than normal for age-matched individuals without BPD (time frame: Baseline). 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 12 May 2023.
