Study population: Kidney transplantation from HBsAg+ donors to HBsAg- recipients

Who may be able to join

  • patients diagnosed with end-stage renal diseases and suitable for living kidney transplantation;
  • HBsAg+ donor was the only donor;
  • age and sex of donors and recipients were unrestricted;
  • ABO compatible or incompatible between the donor and recipient;
  • The living donor voluntarily donates one of their kidneys to the recipient free of charge;
  • The donor and recipient can understand the purpose and risk of living KT and sign informed consent;
  • Ethics committee approved.

Who cannot join

  • preoperative abnormal liver dysfunction in the donor or recipient (ALT > 60IU/L for females, and >75 IU/L for males; or total bilirubin > 34 umol/L); or preoperative ultrasonography in the donor or recipient reported hepatic cirrhosis;

About this study

This is a multicenter, prospective, observational study to compare the efficacy and safety of stratified prophylaxis based on donors' and recipients' risk factors vs routine prophylaxis bases on clinical experience in living kidney transplantation from HBsAg+ donors to HBsAg- recipients. The follow-up period was 2 years after renal transplantation. The primary outcome was prevention failure of HBV transmission (any one of HBsAg - → +, HBV DNA - → +, HBeAg - → +, HBeAb - → +, HBcAb - → +, active liver function damage and death in the recipient).

What participants receive

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

  • prophylaxis regimenOther

    All recipients were divided into two groups: stratified prophylaxis group based on donors' and recipients' characteristics and routine prophylaxis group based on clinical experience

Study groups in NCT04562051
Study groupRoleWhat they receive
stratified prophylaxis groupThe process of stratified prophylaxis was as follows. 1) If the recipient's HBsAb level is more than 100 IU/L and the donor is HBV DNA-, the recipient will not receive any preventive measures; 2) If the recipient's HBsAb is more than 100 IU/L and the donor is HBV DNA+, the recipient receives antiviral treatment for 1 month; 3) If the recipient's HBsAb is between 10 and 100 IU/L, the recipient is treated with single dose HBIG and antiviral treatment for 1 month regardless of the donor's HBV DNA status; 4) If the recipient's HBsAb is less than 10 IU/L, the recipient will receive single dose HBIG and antiviral treatment for 1 month regardless of the donor's HBV DNA status.

What is being measured

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

  1. composite outcome: prevention failure of HBV transmission from HBsAg+ donors to HBsAg- recipients

    The primary outcome is the incidence of prevention failure of HBV transmission from HBsAg+ donors to HBsAg- recipients, which is a composite endpoint. The composite outcome includes HBsAg - → +, HBV DNA - → +, HBeAg - → +, HBeAb - → +, HBcAb - → +, active liver function damage and death in the recipients. Liver function damage is defined as postoperative abnormal liver dysfunction (ALT > 60IU/L for females, and >75 IU/L for males; or total bilirubin > 34 umol/L); or postoperative ultrasonography reported hepatic cirrhosis in the recipient.

    Measured: 2020.9-2025.10

Secondary outcomes (2)
  1. Graft loss

    Graft loss was defined as re-establishment of long-term dialysis or estimated glomerular filtration rate (eGFR) of <15 ml/min.

    Measured: 2020.9-2025.10

  2. biopsy-confirmed acute rejection

    biopsy-confirmed acute rejection was diagnosed clinically based on a significant increase in serum creatinine levels of 50% or more within 3 days, which was not explained by other reasons and confirmed by biopsy.

    Measured: 2020.9-2025.10

Questions about this trial

What is this clinical trial studying?

An observational study of Kidney Transplantation and HBV, run by West China 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 7 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 29 Nov 2023. 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.

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 Tao Lin, PhD (+8618980602093, kidney5@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

composite outcome: prevention failure of HBV transmission from HBsAg+ donors to HBsAg- recipients (time frame: 2020.9-2025.10). 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 29 Nov 2023.
