About this study

Official title: Effectiveness and Safety of Tenofovir Alafenamide for HBV Prophylaxis in HBV Negative Recipients Received Orthotopic Liver Transplant With HBcAb+ Donors

Liver transplantation is currently the only effective way to treat end-stage liver disease.The shortage of donor liver is still the major problem. Incidence of HBcAb+ varies between different regions. The HBcAb positive rate could be as high as 52% in China.HBcAb positive donor liver may enlarge donor pool and thus save ESLD patients. However, the use of HBcAb positive donor liver may induce HBV infection in hepatitis B negative recipient after liver transplantation. Tenofovir alafenamide (TAF) has better stability in plasma and higher liver targeting property in comparison with tenofovir (TDF), with an extra amide bond, which allows strong antiviral effect with much less doses and reducing the renal and bone injury. Our study intends to evaluate the efficacy and safety of HBV prophylaxis treatment of TAF in HBV negative patients after receiving HBcAb positive donor livers.

Read the detailed description

We intent to enroll 30 patients who are HBV negative but received HBcAb+ liver. Antiviral treatment with TAF(25mg/d,oral) will be started on the first day after liver transplantation. Post-operative HBV infection is defined with positive HBV marker (HBsAg) and/or positive HBV DNA after liver transplantation. Primary outcome will be evaluated at 48 weeks. All the patients will be followed up for another at least 1 year to evaluate the long term efficacy and safety of TAF.

The primary endpoint is to calculate de novo HBV infection after liver transplantation when treating with TAF. Secondary endpoint is to evaluate the renal safety of TAF after liver transplantation.

What is being measured

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

  1. De novo HBV infected rate after liver transplantation at 48 weeks

    Primary outcome is to calculate de novo HBV infection after liver transplantation when treating with TAF.

    Measured: 48 weeks

Secondary outcomes (2)
  1. 48 weeks Renal safety of TAF after liver transplantation.

    Secondary outcome is to evaluate changes in renal function (Serum Creatinine, eGFR, β2-MG: Cr, RBP:Cr) at 48 weeks.

    Measured: 48 weeks

  2. 96 weeks Renal safety of TAF after liver transplantation.

    Secondary outcome is to evaluate changes in renal function (Serum Creatinine, eGFR, β2-MG: Cr, RBP:Cr) at 96 weeks.

    Measured: 96 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Tenofovir Alafenamide 25 MG in people with HBV and Liver Transplant Disorder, run by RenJi Hospital.

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 5 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: status not confirmed, as of the sponsor's last update on 11 Jan 2021. 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.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Qiang Xia, MD., Ph.D. (+8602168383775, xiaqiang@shsmu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

De novo HBV infected rate after liver transplantation at 48 weeks (time frame: 48 weeks). 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 11 Jan 2021.
