About this study

Official title: Characterizing the Long-Term Cardiopulmonary Effects of COVID-19 With Hyperpolarized Xenon and Cardiac MRI

The next phase of the COVID-19 pandemic is likely to see a surge in an associated chronic cardiopulmonary disease that will challenge health systems. Recovered patients are presenting with persistent dyspnea at the Duke Pulmonary Post-COVID clinic. Evidence is now mounting that recovered patients have significant residual pulmonary disease, while myocardial injury has also been increasingly reported. To optimally care for these patients, Duke Pulmonary study team must comprehensively assess and monitor the changes in cardiopulmonary function and relate the changes to physiologic and quality of life outcomes. The study team will deploy cutting-edge MRI to fully characterize cardiopulmonary function in enrolled 30 subjects (accrual 23 subjects) at time point 60-120 days post recovery and 6-9 months later. Cardiac MRI will assess the myocardial status and right ventricular function, while hyperpolarized 129Xe MRI will provide a 3D assessment of pulmonary ventilation, interstitial barrier integrity, and pulmonary vascular hemodynamics. The overall objective outlined in this study is to demonstrate the feasibility and value of comprehensive longitudinal imaging characterization of cardiopulmonary structure and function in patients recovered from Covid-19.

Read the detailed description

The proposed research builds on the established sensitivity of Hyperpolarized 129Xe MRI to obstructive and pulmonary vascular lung disease, features expected to represented in the Covid-19 cohort. It further incorporates a new understanding of the possible role of myocardial injury in these recovered patients by combining cutting-edge pulmonary and cardiac MRI.

Although the initial presentation of patients with moderate to severe symptoms of COVID19 infections is dominated by respiratory symptoms, 10% go on to develop persistent post-infection symptoms which are thought to have an inflammatory etiology. Evidence suggests that pathologic activation of the inflammasome persists beyond the acute initial presentation that contributes to the persistent disabling symptoms characterized as "long-haul COVID". For this trial, subjects will be eligible for enrollment if subjects are outpatients with a history of a laboratory-confirmed diagnosis of COVID-19 infection, and after 60 days or longer. The study team will accrual 13 subjects who continue to have respiratory symptoms (i.e., cough, shortness of breath, dyspnea on exertion). An additional 10 subjects engaged in competitive sports and diagnosed with COVID-19 will also be enrolled. These subjects can be asymptomatic or mildly to moderately. Although rare, cardiac impairment has been documented in <2% of these individuals. The study team knowledge, XeMRI has not yet been studied in this specific patient subset.

Existing data highlight significant racial and ethnic disparities with historically underserved minority populations (i.e., Black, LatinX) suffering disproportionately higher infection rates and more severe illness compared to Whites. This is reflected by the population enrolled in the study team RedCAP database and biorepository. As such 30% of subjects enrolled will be required to be from underserved communities.

What is being measured

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

  1. Red Blood Cell to Membrane (RBC:M) Ratio

    To determine cardiopulmonary structure-function abnormalities that characterize early phase COVID-19 recovery.

    Measured: 1 year

  2. Ventilation Defect Percent

    To determine cardiopulmonary structure-function abnormalities that characterize early phase COVID-19 recovery.

    Measured: 1 year

  3. High Membrane Percent

    To determine cardiopulmonary structure-function abnormalities that characterize early phase COVID-19 recovery.

    Measured: 1 year

  4. Red Blood Cell (RBC) Defect Percent

    To determine cardiopulmonary structure-function abnormalities that characterize early phase COVID-19 recovery.

    Measured: 1 year

  5. Red Blood Cell to Membrane (RBC:M) Ratio at 9 Months

    To characterize the evolution of cardiopulmonary abnormalities over 9 months.

    Measured: 9 Months

  6. Ventilation Defect Percent at 9 Months

    To characterize the evolution of cardiopulmonary abnormalities over 9 months.

    Measured: 9 months

  7. High Membrane Percent at 9 Months

    To characterize the evolution of cardiopulmonary abnormalities over 9 months.

    Measured: 9 months

  8. Red Blood Cell (RBC) Defect Percent at 9 Months

    To characterize the evolution of cardiopulmonary abnormalities over 9 months.

    Measured: 9 months

  9. Identify MRI Features That Predict Physiological Outcomes With DLCO (Diffusing Capacity of the Lungs for Carbon Monoxide)

    DLCO is the extent to which oxygen passes from the air sacs of the lungs into the blood.

    Measured: Baseline

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Hyperpolarized 129Xenon gas in people with Covid19, run by Bastiaan Driehuys at 1 site in United States.

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 3 inclusion and 4 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 6 May 2024. 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 United States. 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 6 May 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Red Blood Cell to Membrane (RBC:M) Ratio (time frame: 1 year). The study lists 9 primary outcomes in all. 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 6 May 2024.
