About this study

Official title: A Novel Immunotherapy for Liver Transplant Patients With Hepatocellular Carcinoma: Anti-tumor Effect of IL2-activated Donor Liver Natural Killer Cell

The objective of this study is to evaluate feasibility and safety of the adoptive transfer of activated natural killer (NK) cells extracted from cadaveric donor liver graft perfusate for liver transplant recipients with hepatocellular carcinoma (HCC)

Read the detailed description

To investigate whether adoptive transfer of IL-2 stimulated NKcells extracted from cadaveric donor liver graft exudates into recipient with HCC will lead to prevent recurrence of HCC after liver transplantation.

The method we plan to use is to collect NK cells from the cadaveric donor liver perfusate at the time of organ recovery. The perfusate will be condensed by centrifuging and liver mononuclear cells (LMNC) were isolated by gradient centrifugation. LMNC will be cultured with anti-CD3 antibody. LMNC will be separted into a CD3-/CD56+ NK cell fraction and a non-NK cell fraction. The purity of isolated fractions will be assessed by Flow cytometric analyses. NK cells will be cultured with human recombinant IL-2 in 10% RPMI at 37 ºC in a 5% CO2 incubator. NK cells will be infused intravenously to the recipient with HCC who have liver transplant from the same cadaveric donor at post operative day 4 in attempt to prevent the metastasis and recurrence of HCC.

What participants receive

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

  • Liver NK cell inoculationBiological

    Liver transplant recipients will receive once liver NK cell inoculation several days after liver transplantation.

Study groups in NCT01147380
Study groupRoleWhat they receive
Small doseExperimentalFrom the donor liver perfusate, mononuclear cell will be extracted and cultured. Then, the cells will be stimulated with IL-2. The number of inoculation cells( mainly NK cells) is between 10 and 100 million cells. The cells will be given to the liver transplant recipient who had the same donor for liver and liver perfusate. Patient of this arm receive small dose of liver NK cell inoculation as described.
Receives: Biological: Liver NK cell inoculation
Large doseExperimentalFrom the donor liver perfusate, mononuclear cell will be extracted and cultured. Then, the cells will be stimulated with IL-2. The number of inoculation cells(mainly NK cells) is between 100 and 1000 million cells. The cells will be given to the liver transplant recipient who had the same donor for liver and liver perfusate.Patient of this arm receive large dose of liver NK cell inoculation as described.
Receives: Biological: Liver NK cell inoculation

What is being measured

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

  1. Side Effect of Cadaveric Donor Liver NK Cell Infusion

    Side effect of cadaveric donor liver NK cell infusion We will measure the occurence of the side effect of the liver NK cell infusion. We will monitor the patient condition clinically. If any side effect are noticed, we will record them and report to the data safety monitoring comittee.

    Measured: 1 year

Secondary outcomes (3)
  1. NK Cell Infusion-related Toxicity

    To assess NK cell infusion -related toxicity at the bedside. We will monitor the patient and check the vital sign. If any side effect are noticed, we will record and report to the data safety monitoring comittee.

    Measured: 1 year

  2. Anti-HCC Effect of This Treatment

    Measured: 2 year

  3. Anti-HCV Effect of This Treatment (If Applicable)

    Measured: 2 year

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Liver NK cell inoculation in people with Liver Cirrhosis and Hepatocellular Carcinoma, run by Seigo Nishida 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 9 inclusion and 16 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 10 Mar 2016. 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?

Yes. Results are posted in the registry (first posted 10 Mar 2016). 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?

Side Effect of Cadaveric Donor Liver NK Cell Infusion (time frame: 1 year). 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 NCT01147380, 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 10 Mar 2016.
