About this study

Official title: Adult Stem Therapy for Patients With Liver Insufficiency

In order to determine the clinical application potential of adult stem cells we propose to investigate the safety and toxicity of infusing adult stem cells in the hepatic artery or portal vein of five patients with chronic liver insufficiency and to identify any clinical benefit if such occurs.

Objectives:

  1. To assess safety and treatment related toxicities
  2. To determine clinical benefit or deterioration by monitoring changes in liver function
Read the detailed description

The liver in an adult healthy body maintains a balance between cell gain and cell loss. Though normally proliferatively quiescent, hepatocyte loss such as that caused by partial hepatectomy, uncomplicated by virus infection or inflammation, invokes a rapid regenerative response to restore liver mass. This restoration of moderate cell loss and 'wear and tear' renewal is largely achieved by hepatocyte self-replication. More severe liver injury can activate a potential stem cell compartment located within the intrahepatic biliary tree, giving rise to cords of bipotential, so-called, oval cells within the lobules that can differentiate into hepatocytes and biliary epithelial cells. A third population of stem cells with hepatic potential reside in the bone marrow; these haematopoietic stem cells can contribute to the albeit low renewal rate of hepatocytes, make a more significant contribution to regeneration and even completely restore normal function in a murine model of hereditary tyrosinaemia.

A recent abstract has suggested that an astonishingly high number of bone marrow cells (~25% of liver parenchyma occupied by bone marrow-derived cells) will engraft and differentiate into hepatocytes in a model of cirrhosis in the mouse when injected intravenously. More importantly, this bone marrow infusion resulted in significant improvements in liver function (serum albumin) within the cirrhotic animals.

This is a safety and toxicity study in five patients with chronic liver disease. Each will receive autologous stem cells 10 to the sixth cells via the hepatic artery or portal vein under image guided scanning. Patients will be followed for a total of 60 days.

Questions about this trial

What is this clinical trial studying?

A study testing Leukapheresis and Infusion of stem cells via image guided scan in people with Liver Cirrhosis, run by Imperial College London at 1 site in United Kingdom.

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 1 inclusion and 1 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 Oct 2019. 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 Kingdom. 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?

Yes. Results are posted in the registry (first posted 3 Oct 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?

Number of Participants With Serious Adverse Events Related to Injection (time frame: Day 1 to Day 60). 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 NCT00147043, which also lists 1 linked publication.

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 Oct 2019.
