Trial summary

The mechanism by which heart failure initiates and progresses and the mechanisms of heart repair remain unclear. The left ventricular assist device (LVAD) is a therapy to stabilise patients while they await their transplant. The LVAD helps pump blood around the body, giving the heart an opportunity to recover.

About this study

Official title: Assessing the Effects of Mechanical Unloading on Tissue and Immunologic Characteristics Indictive of Cardiac Repair

The mechanism by which heart failure initiates and progresses and the mechanisms of heart repair remain unclear.

The left ventricular assist device (LVAD) is a therapy to stabilise patients while they await their transplant. The LVAD helps pump blood around the body, giving the heart an opportunity to recover. During surgery, the apical core tissue is routinely removed to allow the implantation of the device (this tissue is normally discarded). Some patients demonstrate cardiac recovery, allowing the device to be removed without later needing a transplant. As part of the LVAD removal procedure, the section around the device might need to be removed (this tissue is normally discarded). To further understand the cellular and molecular mechanisms by which the heart is repaired, the investigators wish to utilise this surplus tissue for research purposes. The collection of this tissue is part of routine treatment and does not represent additional risk for the patient for research purposes. Some patients might still require a transplant following VAD treatment. The native heart is removed from these patients (routinely discarded) and replaced by a donor heart. The investigators wish to utilise this discarded tissue for research purposes, so that the investigators can identify the cellular and molecular factors involved in cardiac repair and which distinguish responsive and non-responsive patients. Heart transplant recipients who require extracorporeal membrane oxygenation will have an additional heart biopsy sample taken for research purposes when performed as part of routine clinical practice. There is no additional risk to the patient for research purposes. Heart failure patients scheduled for transplantation (who have not received a VAD) will be recruited prior to transplantation and their native heart retained for research purposes. An additional peripheral blood sample will be collected from all patients for research purposes when performed for routine clinical practice.

What participants receive

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

Study groups in NCT06026215
Study groupRoleWhat they receive
Group 1Heart failure patients requiring ventricular assist device implantation will be included into group 1.
Group 2Heart transplant recipients requiring early extracorporeal membrane oxygenation will be recruited into group 2.
Group 3Heart transplant recipients who have not previously received a VAD will be recruited into group 3.

What is being measured

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

  1. Changes in protein expression within the tissue during clinical repair.

    Relate small changes in protein expression within the heart tissue to clinical parameters indicative of function. Additionally, the investigators aim to extend our understanding of the mechanisms underpinning heart failure by identifying the factors responsible for either preventing repair or promoting expedited disease progression.

    Measured: through study completion - 4 years

Questions about this trial

What is this clinical trial studying?

An observational study of Heart Failure and Transplant; Failure, Heart, run by Manchester University NHS Foundation Trust.

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 4 inclusion and 3 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 7 Sep 2023. Status can change between updates, so confirm with the study contact before making plans.

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?

Changes in protein expression within the tissue during clinical repair. (time frame: through study completion - 4 years). 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 7 Sep 2023.
