  • Ages Up to 21 years
  • All sexes
  • No healthy volunteers
  • Child, Adult

Who may be able to join

  • Patients will have life-threatening liver-based metabolic disorders who are candidates for organ transplantation where hepatocyte transplantation is considered theoretically curative.
  • In addition to child subjects less than 18 years of age, for purposes of this protocol, adults up to age 21 years will be enrolled since this is the upper age limit of patients which are seen at Children's Hospital of Pittsburgh.

Who cannot join

  • Subjects who meet any of the following criteria will be excluded from participation in this protocol:
  • Subject has active malignancy.
  • Subject has allergy to immunosuppression medications that are required post transplant procedure for the prevention of rejection.
  • Subject has sepsis, pneumonia, other active infection or other secondary life-threatening organ dysfunction.
  • Significant liver fibrosis determined by biopsy (if clinically indicated). Significant liver fibrosis will be defined by the Ishak Staging, Stage 5: bridges with occasional nodules.

About this study

The purpose of this research study is to determine whether partial irradiation of the liver and liver cell transplantation can provide help for patients with life-threatening liver-based metabolic diseases who are unlikely to survive without extensive medical therapy or transplant. The goal of this research study is to determine if liver cell transplants can be effective as an alternative to organ transplantation. At the present time, liver cell transplants are experimental and have been done in a limited number of human subjects.

Read the detailed description

Management of patients with hepatic failure and liver-based metabolic disorders is complex and expensive. Hepatic failure results in impaired coagulation, altered consciousness and cerebral function, a heightened risk of multiple organ system failure, and sepsis. Liver transplantation is often the only available treatment option for severe, even if transient, hepatic failure. Patients with life-threatening liver-based metabolic disorders similarly require organ transplantation even though their metabolic diseases are typically the result of a single enzyme deficiency, and the liver otherwise functions normally. More than 17,000 patients currently await liver transplantation in the United States, a number that seriously underestimates the number of patients that need treatment, as it has been estimated that more than a million patients in the United States could benefit from transplantation. Unfortunately, use of whole liver transplantation to treat these disorders is limited by a severe shortage of donors and by the risks associated with major surgery. Hepatocyte transplantation holds great promise as an alternative to organ transplantation for the treatment of liver diseases, and numerous studies in rodents indicate that transplants consisting of isolated liver cells can correct various metabolic deficiencies of the liver and can reverse hepatic failure. The transplant procedure, which involves injection of isolated hepatocytes into the liver through the portal vein, is far less intrusive than transplantation of the whole liver and could be performed on severely ill patients with relatively low risk. In the presence of normal host liver architecture, the transplanted cells integrate into the host liver, providing considerable restorative potential. Because the native liver is not removed, the transplanted hepatocytes need only improve some of the functions of the failing liver and need not replace all hepatic functions. Although clinical trials of hepatocyte transplantation have demonstrated the long-term safety of the procedure, only partial correction of metabolic disorders has been achieved, and the degree to which donor hepatocytes have restored failing livers has not been adequate to circumvent the need for organ replacement.

What participants receive

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

  • human hepatocyte transplantationDrug

    Also called hepatocyte transplant

    Transplantation of hepatocytes into the liver will be through the portal vein. The portal vein will be accessed transhepatically, by umbilical vein, or surgically by a peripheral mesenteric vein.

    The subject will be evaluated de novo and if they are a candidate for orthotopic liver transplantation they will receive the transplant. Even if the subject receives the hepatocyte transplant and it does not work, they will be evaluated for orthotopic liver transplantation as if they never received the hepatocyte transplant.

    If at 6 months we see an improvement in disease, we will recommend a re-transplantation with a goal of complete correction of disease and until the subject is no longer required to be a candidate for organ transplantation. Subjects will be re-evaluated every 6 months for re-transplantation. Subjects will remain on the waiting list for organ transplantation. Further radiation therapy will not be needed prior to re-transplantation.

  • Preparative Radiation TherapyRadiation

    Just prior to the hepatocyte transplant, a portion of the right hepatic lobe comprising between 35-50% of the entire liver volume will be irradiated to a dose of 7.5-10 Gy in a single fraction using a linear accelerator-based stereotactic radiosurgery system with intensity-modulated radiation therapy planning (IMRT).

What is being measured

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

  1. Improvement in enzyme physiologic function at 6 months

    After infusing donor allogeneic hepatocytes through the portal vein following preparative hepatic irradiation, improvement in enzyme physiologic function will be assessed at 6 months.

    Measured: 6 months post hepatocyte transplant

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing human hepatocyte transplantation and Preparative Radiation Therapy in people with Metabolic Diseases, run by Ira Fox 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 2 inclusion and 7 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 7 Dec 2022. 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 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 stopped early (reason given: seeking additional funding). Results are not available in the source record.

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?

Improvement in enzyme physiologic function at 6 months (time frame: 6 months post hepatocyte 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 NCT01345578, which also lists 6 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 7 Dec 2022.
