About this study

Official title: A Phase II Trial to Assess the Safety of Immunosuppression Withdrawal in Liver Transplant Recipients

In order to prevent organ rejection, patients receiving liver transplants currently require life-long treatment with immune system-suppressing medications to prevent the rejection of the transplanted liver. However, these medications can cause long-term side effects, such as infection, kidney problems, diabetes, and cancer. In patients infected with hepatitis C virus (HCV), these medications may increase the risk of HCV infection in the transplanted liver. The purpose of this study is to determine whether a slow withdrawal of immune system-suppressing medications is safe in two groups of subjects: those who receive a liver transplant due to HCV, and those who receive a liver transplant due to non-immune, non-viral causes of liver failure. The study will also look at whether slow withdrawal will help reduce the long-term side effects of immune system-suppressing medications and decrease the chance for HCV infection of the new liver in transplant patients with HCV.

Read the detailed description

This is a prospective multicenter, open-label, randomized trial in which individuals with liver failure due to hepatitis C or to nonimmune nonviral causes undergo liver transplantation and receive immunosuppression with a calcineurin inhibitor and corticosteroids. Corticosteroids are tapered in the 3 months after transplantation and the calcineurin inhibitor is continued. Participants are regularly assessed for evidence of allograft rejection. One year after transplantation, participants eligible for withdrawal are randomly assigned in a 4 to 1 ratio to immunosuppression withdrawal or to maintenance. Participants assigned to withdrawal undergo a scheduled taper over approximately 1 year.

What is being measured

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

  1. Number of Participants With Clinical Complications Usually Attributed to Immunosuppression

    This is a composite endpoint comprising clinical complications related to immunosuppression and is defined as the occurrence of any of the following: death or graft loss, grade 4 secondary malignancy (graded by Common Terminology Criteria for Adverse Events [CTCAE] version 3.0), grade 4 opportunistic infection (graded by CTCAE version 3.0), stage 3 or higher fibrosis, or decrease in renal function. Decrease in renal function is defined as: a) the estimated glomerular filtration rate (eGFR) using creatinine obtained prior to and closest to randomization will be considered the baseline and will be compared to the eGFR using creatinine obtained at 24 months +/- 3 months after randomization; b) for those with a baseline eGFR 30-90 ml per min per 1.73 meter-squared, a 25% decrease in eGFR; c) for those with a baseline eGFR greater than 90 ml per min per 1.73 meter-squared, a 25% decrease in eGFR and a decrease in eGFR to less than 90 ml per min per 1.73 meter-squared.

    Measured: Randomization to 2 years post-randomization

Secondary outcomes (7)
  1. Number of Participants Who Qualify for Random Assignment

    Measured: One to two years post-transplantation

  2. Number of Participants Who Successfully Stop Taking Immunosuppression for at Least 6 Months

    Measured: Randomization until study completion or participant termination (up to six years post-transplant)

  3. Immunosuppression-free Duration

    Time (in days) from withdrawing off of all immunosuppressive drugs to re-starting immunosuppression or study termination/completion.

    Measured: Discontinuation of all immunosuppression to end of trial participation or to time of restarting immunosuppression, whichever came first, assessed up to two years

  4. Number of Hepatitis C Infected Participants With Progression of Hepatitis C Related Liver Disease, Defined as Stage 4 or Higher Fibrosis on the Ishak Scale

    Number of subjects with a biopsy showing stage 4 fibrosis or higher on the Ishak scale. Stage 4 represents at least 13.7% fibrosis measurement with a description of fibrous expansion of portal areas with marked bridging (P-P) as well as portal to central (P-C). Stage 5 is marked bridging (P-P and/or P-C), with occasional nodules (incomplete cirrhosis) and stage 6 is cirrhosis, probable or definite.

    Measured: Randomization to 2 years post-randomization.

  5. Number of Participants Experiencing Graft Loss or Death

    Number of participants with graft loss or death. Graft loss is defined as subject death or re-transplantation.

    Measured: Randomization to 2 years post-randomization.

  6. Total Immunosuppression From Month 21 to Month 24 Post-randomization

    Daily immunosuppression score in units per day averaged over the 3-month period from Month 21 to Month 24 post-randomization. Daily doses were assigned a score of 1 unit as follows: tacrolimus 1 mg, cyclosporine 100 mg, Sirolimus 1 mg, mycophenolate mofetil 1000 mg, Mycophenolic acid 720 mg, azathioprine 50 mg, and prednisone 5 mg. Any antibody use equaled 20 units. Unit scores based on Vasudev (Vasudev B, Hariharan S, Hussain SA, Zhu YR, Bresnahan BA et al. BK virus nephritis: risk factors, timing, and outcome in renal transplant recipients. Kidney Int. 2005; 8(4):1834-1839.)

    Measured: Month 21 to Month 24 post-randomization

  7. Total Burden of Immunosuppression From Random Assignment to Month 24

    Total immunosuppression score in units taken as the sum of units per day over the 2-year period from randomization to Month 24 post-randomization. Daily doses were assigned a score of 1 unit as follows: tacrolimus 1 mg, cyclosporine 100 mg, Sirolimus 1 mg, mycophenolate mofetil 1000 mg, Mycophenolic acid 720 mg, azathioprine 50 mg, and prednisone 5 mg. Any antibody use equaled 20 units. Unit scores based on Vasudev (Vasudev B, Hariharan S, Hussain SA, Zhu YR, Bresnahan BA et al. BK virus nephritis: risk factors, timing, and outcome in renal transplant recipients. Kidney Int. 2005; 8(4):1834-1839.).

    Measured: Randomization to Month 24 post-randomization

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 6 inclusion and 17 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 4 Feb 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites 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 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?

Yes. Results are posted in the registry (first posted 8 Dec 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?

Number of Participants With Clinical Complications Usually Attributed to Immunosuppression (time frame: Randomization to 2 years post-randomization). 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 NCT00135694, which also lists 2 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 4 Feb 2019.
