About this study

Official title: Donor Specific Regulation (DSR) Guided Tacrolimus Withdrawal to Myfortic Monotherapy in Liver Transplantation

To determine whether long-term maintenance therapy with a single drug (Myfortic) applied using advanced immunologic monitoring tools in selected patients can lead to superior native kidney function at 2 years without resulting in increased acute rejection episodes or deterioration of liver allograft function.

Read the detailed description

The hypothesis to be tested is that donor-microchimerism in specific cell populations promotes the development of donor-specific regulation which in turn allows for long-term maintenance therapy with a single drug (Myfortic) in selected patients leading to superior long-term outcomes. Subjects will be enrolled post-transplantation and will be liver transplant recipients who meet the eligibility and exclusion criteria. We will use post-transplant monitoring for donor-specific immunologic regulation (DSR+/ DSA negative) to direct the withdrawal of patients to Myfortic monotherapy. Donor microchimerism, DSR, DSA development will be performed on samples obtained every six months from patients on study. The ultimate objective of the study is to use immunologic monitoring to develop a rational approach to achieving individualized immunosuppression for liver transplant patients.

What participants receive

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

  • Group 1 Donor Specific Regulation (DSR) +, Mycophenolic acid (MPA) monotherapyDrug

    Also called Myfortic

    Group 1 Donor Specific Regulation (DSR) +, MPA monotherapy

    Mycophenolate sodium : Myfortic therapy will be maintained at a target dose of 720mg BID.

    Tacrolimus doses will be lowered to achieve levels of 3-5 ng/ml. 6 months later, immunological monitoring will be repeated and tacrolimus will be completely discontinued if the subject remains DSR + without development of donor specific antibodies (DSA). Those who become DSR- or develop DSA will remain on a tacrolimus dose achieving levels of 3-5 ng/ml, and will not undergone any additional reduction.

    Subjects will be followed for 24 months at 6 month intervals, and will provide health information and blood samples.

  • data and sample collectionOther

    Group 2 : Donor specific regulation (DSR) + standard of care:

    These subjects will be maintained on standard of care immunosuppression consisting of Tacrolimus and Mycophenolate sodium (MPS) with no reduction in tacrolimus dose during the 24 months of study enrollment.

    Subjects will be followed for 24 months at 6 month intervals, and will provide health information and blood samples

  • data and sample collectionOther

    Group 3 : Donor specific regulation (DSR) - standard of care:

    These subjects are those who were DSR negative and/or DSA positive at enrollment and therefore are not eligible for the withdrawal aspect of the study. These subjects will be maintained on standard of care immunosuppression consisting of Tacrolimus and Mycophenolate sodium (MPS) with no reduction in tacrolimus dose during the 24 months of study enrollment. These subjects will be asked to provide heath information and donate blood, exclusively for research testing, at the same 6 month intervals as those in the other two arms of the study, and will be followed for 24 months.

What is being measured

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

  1. Modification of Diet in Renal Disease (MDRD) Estimation of Glomerular Filtration Rate (GFR)

    This outcome measure is used to determine if the reduction of calcineurin inhibitor immunosuppression leads to improved native kidney function. Native kidney function is assessed using the Modification of Diet in Renal Disease (MDRD) estimation of glomerular filtration rate (GFR) from serum or plasma creatinine samples at the reported time points.

    Reference intervals include:

    Healthy 18 years and up: 60-120 mL/min/1.73 sqm Chronic kidney disease: GFR < 60 mL/min/1.73 sqm Kidney failure: GFR < 15 mL/min/1.73 sqm

    Measured: 6 months post enrollment/randomization

  2. Modification of Diet in Renal Disease (MDRD) Estimation of Glomerular Filtration Rate (GFR)

    This outcome measure is used to determine if the reduction of calcineurin inhibitor immunosuppression leads to improved native kidney function. Native kidney function is assessed using the Modification of Diet in Renal Disease (MDRD) estimation of glomerular filtration rate (GFR) from serum or plasma creatinine samples at the reported time points.

    Reference intervals include:

    Healthy 18 years and up: 60-120 mL/min/1.73 sqm Chronic kidney disease: GFR < 60 mL/min/1.73 sqm Kidney failure: GFR < 15 mL/min/1.73 sqm

    Measured: 12 months post enrollment/randomization

Questions about this trial

What is this clinical trial studying?

A study testing Group 1 Donor Specific Regulation (DSR) +, Mycophenolic acid (MPA) monotherapy and data and sample collection in people with Liver Transplant, run by University of Wisconsin, Madison 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 2 inclusion and 19 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: stopped early, as of the sponsor's last update on 7 May 2014. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 7 May 2014). 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?

Modification of Diet in Renal Disease (MDRD) Estimation of Glomerular Filtration Rate (GFR) (time frame: 6 months post enrollment/randomization). The study lists 2 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 7 May 2014.
