Trial summary

All individuals who receive a heart transplant are at risk for developing antibody-mediated rejection (AMR). An antibody is a protein produced by the body's immune system when it detects a foreign substance, called an antigen. The mechanism of an antibody is to attack an antigen. Read more about this study

About this study

Official title: The De-novo Use of Eculizumab Alongside Conventional Therapy in Presensitized Patients Receiving Cardiac Transplantation: An Open-Label, Investigator-Initiated Pilot Trial: [The DUET Cardiac Trial]

All individuals who receive a heart transplant are at risk for developing antibody-mediated rejection (AMR). An antibody is a protein produced by the body's immune system when it detects a foreign substance, called an antigen. The mechanism of an antibody is to attack an antigen. In antibody mediated rejection, antibodies will attack the transplanted heart, causing injury to the heart. The purpose of this investigation is to determine if a study drug, called eculizumab (Soliris), is safe to use in heart transplant recipients, and determine if it reduces risk of antibody-mediated rejection.

Read the detailed description

The growing proportion of sensitized cardiac recipients presents an additional challenge to the transplant practitioner attempting to minimize the occurrence of antibody mediated rejection (AMR). Patients pre-exposed or "sensitized" to antigen exposing events (i.e.: blood transfusions, multiple pregnancies, prior organ transplantations, ventricular support devices) are more likely to both possess preformed and develop de-novo antibodies. Sensitized patients with panel reactive antibodies > 25% are at risk for increased risk of rejection, development of cardiac allograft vasculopathy and increased mortality after heart transplantation.

A central component of antibody-mediated cell injury is complement activation. The inhibition of terminal complement activation may be the missing link to decreasing possibly both complement-mediated AMR and cellular rejection (CR) by inhibiting both the inflammatory effects of both circulating antibodies and cytokine induced cell death.

Eculizumab is a monoclonal antibody that specifically binds to complement protein C5 with high affinity, thereby inhibiting its cleavage to C5a and C5b and preventing the generation of the terminal complement complex C5b-9. By this mechanism, eculizumab (Soliris®) inhibits terminal complement mediated intravascular hemolysis in paroxysmal nocturnal hemoglobinuria patients.

This study is a non-randomized, open-label, investigator-initiated safety and efficacy trial investigating the de-novo use of eculizumab alongside conventional therapy to prevent antibody mediated rejection. The duration of the study will include an open enrollment period and at least 12 months of follow-up (post-transplant). We will consent up to 45 eligible patients, highly "sensitized", with a panel reactive antibody score greater than 70%, who are not previously or currently enrolled in another ongoing trial. Of these 45 participants, up to 20 of these patients will be treated with eculizumab (Solaris), the study drug. The use of eculizumab will be un-blinded to all study and research practitioner participants.

What participants receive

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

  • EculizumabDrug

    Also called Soliris

    At the time of transplantation, 1200mg of Eculizumab will be administered via a 35 minute IV infusion, followed by thymoglobulin 1.5 mg/kg intravenous piggyback (IVPB). The administration of thymoglobulin will be repeated (if blood counts permit) for a total of five doses.

    On Day 1 post-transplant, 900 mg of Eculizumab will be given via an IV infusion.

    On Day 5 post-transplant, intravenous immunoglobulin (IVIG) 1 gram/kg will be administered daily for two consecutive days.

    On post-transplant days 7, 14, and 21 (+/- 2 days) 900mg of Eculizumab will be given via an IV infusion at each scheduled visit.

    On post-transplant days 28, 42, and 56 (+/- 2 days) 1200 mg of Eculizumab will be given via an IV infusion at each scheduled visit.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Eculizumab in people with Antibody-mediated Rejection and Hyperacute Rejection of Cardiac Transplant, run by Cedars-Sinai Medical Center 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 6 inclusion and 10 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 3 May 2021. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 3 May 2021). 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?

Number of Participants of Pathologic Antibody-Mediated Rejection and Left Ventricular Dysfunction (time frame: up to 26 weeks post heart transplant). 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 NCT02013037, which also lists 14 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 3 May 2021.
