About this study

Official title: Conversion From Tacrolimus to Envarsus in Rapid Metabolizers Post Kidney Transplant Protects Against BK Infection

The purpose of this study is to assess if the use of Envarsus in place of Tacrolimus-immediate release (IR) in rapid metabolizers post kidney transplant will reduce incidence of BK infection. Efficacy evaluations will include measurement of urine and serum BK values at specified time points and review of any biopsy for BK virus nephropathy. Incidence of rejection, graft failure, and graft dysfunction will also be measured at specified time points.

Read the detailed description

This will be a single center prospective case control study. The investigators expect 40% of patients will develop BK viruria, 20% BK viremia, 5% BK viral nephropathy (BKVN). Patients will be managed using standard of care for the investigator's center (thymoglobulin induction, tacrolimus/mycophenolate/prednisone). Target tacrolimus level is 8-12 ng/mL for the first 6 months post transplant and 6-9 ng/mL thereafter. BK urine/serum is monitored at 1, 3, 6, 9, 2 months post transplant. A population of 100 patients is calculated to show significant difference for p value < 0.05.

Population:

Study Group: Post transplant patients (kidney transplant alone) with standard of care immunosuppression, no prior rejection, prior BK or opportunistic infection, and negative BK screening at post-transplant month 1, who have a tacrolimus concentration/dose of < 1 and a steady state therapeutic level will be eligible. Patients who consent will be converted to Envarsus at 20% reduction in tacrolimus dose.

Control Group: Post transplant patients (kidney transplant alone performed between 10-2016 and time of enrollment) with standard of care immunosuppression, no prior rejection, prior BK or opportunistic infection, whom had a negative BK screening at post-transplant month 1 and tacrolimus concentration/dose of < 1 at post-transplant month 1, and BK data available for months 2, 3, 6, 9,12 post transplant.

What participants receive

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

  • Study GroupDrug

    Also called tacrolimus extended-release tablets

    Patients will convert from current tacrolimus dose to an Envarsus dose that is 80% of the total tacrolimus dose. They will take envarsus once daily in the morning and have 24 hour trough levels monitored at the standard of care interval for tacrolimus. Dosing will be titrated to achieve goal levels.

  • Control GroupDrug

    Also called Tacrolimus

    Post transplant patients (kidney transplant alone) performed between 10-2016 and time of enrollment with standard of care immunosuppression, no prior rejection, prior BK or opportunistic infection, whom had a negative BK screening at month 1 and concentration/dose of < 1 at month 1, and BK data available and month 2,3, 6,9,12.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Study Group in people with Renal Transplant Infection, run by University of Alabama at Birmingham 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 7 inclusion and 10 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 27 Jul 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 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 27 Jul 2023). 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?

Participants Will Experience Less BK Infection Episodes Based on Viruria Results. (time frame: From baseline to 30 days). The study lists 16 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 27 Jul 2023.
