Liver Transplantation With ADV-TK Gene Therapy Improves Survival in Patients With Advanced Hepatocellular Carcinoma

Trial summary

Previous rather poor results in liver transplantation (LT) of patients with advanced hepatocellular carcinoma (HCC) have made the application of LT very limited in treatment of HCC. The advantages of ADV-TK gene therapy highlight its potentiality as adjuvant treatment for HCC patients after LT. Read more about this study

About this study

Previous rather poor results in liver transplantation (LT) of patients with advanced hepatocellular carcinoma (HCC) have made the application of LT very limited in treatment of HCC. The advantages of ADV-TK gene therapy highlight its potentiality as adjuvant treatment for HCC patients after LT. We reported here the improved outcome of LT with combined treatment of ADV-TK gene therapy in patients with intermediate or advanced HCC.

Read the detailed description

The overall survival in the LT with ADV-TK gene therapy group was 54.8 % at three years, and the recurrence-free survival in the same group was 56.5 %, both being higher than those in the transplantation only group (P=0.0001 for overall survival and P=0.0000 for recurrence-free survival). In no-vascular invasion subgroup treated with LT with ADV-TK therapy, both overall survival and recurrence-free survival were 100 %, significantly higher than those with vascular invasion subgroup treated with the combined LT and ADV-TK therapy (P=0 for each group). Vascular invasion was an important factor affected survival and recurrence, hazard ratio=3.687; P=0.014 and hazard ratio=12.961; P=0.000, respectively.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing ADV-TK (adenovirus-thymidine kinase enzyme) gene therapy in people with Hepatocellular Carcinoma and Liver Transplantation, run by Beijing Chao Yang Hospital at 1 site in China.

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 2 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 9 Mar 2006. 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 China. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

overall survival rate at one year. The study lists 6 primary outcomes in all. 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 9 Mar 2006.
