About this study

Official title: The Effect of Intramyocardial Injection of Immunoselected Bone Marrow Cells on Myocardial Function in LVAD Bridge to Transplant Patients

Heart failure is a condition in which the heart is unable to pump enough blood to the body's other organs. A heart transplant may be necessary for some individuals with end-stage heart failure. Left ventricular assist devices (LVADs) can assist the heart in pumping blood, and are commonly used until a donor heart becomes available. Bone marrow cells injected into the heart may improve heart function and may lead to earlier LVAD removal. The purpose of this study is to evaluate the safety and effectiveness of injected bone marrow cells in improving heart function in individuals with LVADs who are awaiting heart transplants.

Read the detailed description

Congestive heart failure affects 5 million people in the United States, and over 60,000 are diagnosed with end-stage heart failure. Treatment options for these individuals are extremely limited. Because of a limited supply of donor organs, fewer than 3,000 people receive heart transplants each year. LVADs are battery-operated devices that can act as a temporary solution until a donor heart becomes available. Upon being surgically implanted into a weakened heart, the LVAD mechanically pumps blood from the heart to the rest of the body. There are, however, serious risks associated with LVADs, including infection, blood clots, and stroke. Early removal of the LVAD may be possible by injecting stem cells to regenerate new heart cells and improve heart function. The purpose of this study is to compare the safety and effectiveness of two types of bone marrow cells -- bone marrow mononuclear cells (BMCs) and immunoselected CD34+ hematopoietic stem cells -- in improving heart function in individuals with end-stage heart failure.

This study will enroll individuals undergoing surgery to receive an LVAD. Participants will be randomly assigned to one of following three groups:

Group 1 (n=30): participants will undergo intramyocardial injection of bone marrow mononuclear cells (BMCs) during LVAD implantation

Group 2 (n=30): participants will undergo intramyocardial injection of immunoselected CD34+ hematopoietic stem cells during LVAD implantation

Group 3 (n=15): participants will undergo LVAD implantation

Prior to LVAD implantation, participants in Groups 1 and 2 will have a sample of bone marrow removed. Following LVAD implantation, study visits will occur at Days 45 and 90, and then every 60 days thereafter until participants receive a heart transplant. At each visit, participants will undergo a LVAD wean procedure, during which the mechanical pump of the LVAD will be gradually turned off, and the LVAD will be operated with a hand pump. The length of time that a participant tolerates the wean procedure will be evaluated. Heart size and function, blood flow, and nerve function will also be assessed. Some participants will undergo a 6-minute walk test. At the time of heart transplant surgery, the LVAD will be removed, and heart cell regeneration and heart function will be evaluated.

What participants receive

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

  • Intramyocardial injection of bone marrow mononuclear cellsBiological

    Also called CD34+ selected BMCs + LVAD

    6mL of CD34+ selected bone marrow mononuclear cells will be injected into the myocardium during LVAD implantation.

  • LVAD aloneDevice

What is being measured

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

  1. Duration of Time (Minutes) a Patient is Able to Tolerate Wean

    This defines the functional status. Due to poor enrollment, data was not analyzed.

    Measured: Measured 90 days post-intervention

Secondary outcomes (2)
  1. Prevalence of Normal Echocardiographic Assessments

    Echocardiographic assessments of myocardial size and function by transthoracic echocardiography with the LVAD at full support, and as tolerated at 1, 5, 10 and 15 minutes following initiation of hand pumping.

    Due to poor enrollment, data was not analyzed.

    Measured: Measured at baseline, Days 45 and 90 post-intervention, every 60 days thereafter until transplant

  2. Number of Patients Who Completed a Six Minute Walk

    6 Minute walk as tolerated at 15 minutes following initiation of hand pumping.

    Due to poor enrollment, results was not analyzed.

    Measured: Measured at Days 45 and 90 post-intervention, every 60 days thereafter until transplant

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Intramyocardial injection of bone marrow mononuclear cells, Intramyocardial injection of CD34+ selected bone marrow mononuclear cells and LVAD alone in people with Heart Failure, Congestive, run by Columbia University at 7 sites 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 8 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: stopped early, as of the sponsor's last update on 17 Apr 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites 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 17 Apr 2019). 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?

Duration of Time (Minutes) a Patient is Able to Tolerate Wean (time frame: Measured 90 days post-intervention). 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 17 Apr 2019; AzTrials last refreshed its copy on 3 Nov 2026.
