Trial summary

Lung transplant is a viable treatment strategy for many with end-stage lung diseases. Despite advances in both the surgical and medical management, lung transplant recipients experience episodes of allograft insult and injury that lead to dysfunction and ultimately contribute to graft failure.

About this study

Official title: A Longitudinal Study of Donor-Derived Cell Free DNA in Lung Transplant

Lung transplant is a viable treatment strategy for many with end-stage lung diseases. Despite advances in both the surgical and medical management, lung transplant recipients experience episodes of allograft insult and injury that lead to dysfunction and ultimately contribute to graft failure. The primary noninvasive tool for monitoring the lung allograft, pulmonary function testing, is neither sensitive nor specific for lung allograft injury which makes the management of lung transplant recipients particularly challenging. A decline in pulmonary function tests prompts invasive procedures such as bronchoscopy with transbronchial lung biopsy to diagnose the cause of allograft injury, although this, too, is not 100% sensitive, and oftentimes patients are treated empirically for rejection when no other etiology for lung function decline is identified. Empiric treatment prompted by extrapulmonary drivers of decline in lung function may result in inappropriate exposure to risks of augmented immunosuppression. The purpose of this study is to determine to what extent monitoring of donor-derived cell free DNA in lung transplant recipients can be used as a marker of lung injury and stability.

What is being measured

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

  1. Relationship

    Determine the relationship between donor derived cell free DNA and lung allograft function during the first year after lung transplant.

    Measured: 12 Months

Secondary outcomes (1)

  1. Quantitative Assessments

    Quantitative assessments of dd-cfDNA obtained at pre-specified timepoints post-transplant compared to clinical events (PGD scores, detection of allograft dysfunction, rejection, or infection).

    Measured: 12 Months

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.

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?

Relationship (time frame: 12 Months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04234919, which also lists 17 linked publications.

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 2 Nov 2022.
