Trial summary

The primary objective is to determine whether donor stem cells administered via hepatic artery infusion can produce liver cells in patients with severe hepatic dysfunction post stem cell transplantation (SCT) and the safety of this procedure. The secondary objective is to improve liver function and improve survival. Read more about this study

About this study

Official title: Hepatic Artery Infusion of CD34+ Cells, Isolated by the Isolex 300i Device, in Stem Cell Transplant Recipients With Hepatic Failure Due to Veno-occlusive Disease

The primary objective is to determine whether donor stem cells administered via hepatic artery infusion can produce liver cells in patients with severe hepatic dysfunction post stem cell transplantation (SCT) and the safety of this procedure. The secondary objective is to improve liver function and improve survival.

Read the detailed description

Participants in this study have received stem cell transplantation. As a result of this procedure, participants have developed severe liver dysfunction. Researchers have recently discovered that cells circulating in the blood and bone marrow are capable of forming liver cells. Before taking part in this study, women able to have children must have a negative blood pregnancy test.

Participants in this study will have donor's cells infused directly into their liver through a catheter that will be inserted through the groin. This will be done after liver disease has been diagnosed by liver biopsy. The catheter will stay in the groin for no more than 3 days. During that time, participants will be exposed to repeated x-ray exams to ensure that the catheter stays in place.

During the time that the catheter is in place, the infusion will be repeated as long as donor's cells are available. Participants will receive different drugs by vein to decrease the risk of transfusion reaction. After completing donor cell infusion, the catheter will be removed.

After participants are released from the hospital, they will have periodic evaluation of liver size. About 1 teaspoon of blood will be drawn for standard blood tests to evaluate liver function. Around Days 28 and 90, participants will have liver biopsy.

This is an investigational study. A total of 10 patients will take part in this study. All will be enrolled at UTMDACC.

What participants receive

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

  • Hepatic artery infusion of CD34+ cellsProcedure or surgery

    Donor's cells infused directly into liver through a groin catheter (hepatic artery).

  • Cobe SpectraDevice

    Also called blood cell separator

    Mononuclear cells (MNC) collected by continuous-flow centrifugation using a blood cell separator (Cobe Spectra).

Study groupRoleWhat they receive
Hepatic Artery InfusionExperimentalDonor-derived CD34+ cells administered in a total volume of 100ml via hepatic artery over 10 minutes. Cells given as a dose escalation study. First cohort of 3 patients receive 1 * 106 CD34+ cells/kg. Next 3 patients receive 2.5 * 106 CD34+cells/kg. Next 3 patients receive 5 * 106 CD34+ cells/kg. Less than 1 * 105 T cells/kg administered.
Receives: Procedure: Hepatic artery infusion of CD34+ cells; Device: Cobe Spectra

What is being measured

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

  1. Learn if donor's cells can produce liver cells when injected directly into the liver and whether this procedure will improve liver function and survival.

    Measured: 3 Years

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Hepatic artery infusion of CD34+ cells and Cobe Spectra in people with Stem Cell Transplantation and Liver Diseases, run by M.D. Anderson Cancer Center.

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: withdrawn, as of the sponsor's last update on 29 Oct 2018. 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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

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?

Learn if donor's cells can produce liver cells when injected directly into the liver and whether this procedure will improve liver function and survival. (time frame: 3 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 29 Oct 2018.
