About this study
Official title: A Prospective, Pilot Trial to Compare the Efficacy of Tacrolimus Extended-Release (Envarsus XR) to Tacrolimus Immediate-Release on Suppression of Donor-Specific Antibodies in HLA Sensitized Kidney Transplant Recipients
This is a randomized, open-label, controlled clinical trial designed to compare clinical outcomes after kidney transplantation using extended-release tacrolimus (Envarsus XR) versus immediate tacrolimus among highly-sensitized kidney transplant recipients. Outcomes to be assessed include the incidence of biopsy-proven acute rejection at 12 months, the presence of de novo and pre-existing donor-specific HLA antibodies, estimated glomerular filtration rate, and the level of donor-derived cell-free DNA.
Read the detailed description
Extended-release tacrolimus (Envarsus XR) received FDA approval in July, 2015 for the prevention of allograft rejection in kidney transplantation on the basis of two separate phase 3 trials of de novo and stable kidney transplant recipients that demonstrated non-inferiority to immediate-release tacrolimus for the composite outcome of death, graft failure, biopsy-proven acute rejection, or loss to follow-up within 12 months (1,2).
Both phase 3 trials involved mostly low immunologic risk recipients with follow-up to one year. It has been previously shown that the incidence of de novo donor-specific antibodies (DSA) in the first year after kidney transplant in low-immunologic patients is low, developing in only 2%-11% of unsensitized de novo kidney transplant recipients (3-6). Donor-specific antibodies (DSA) are the primary mediator of antibody-mediated rejection and their development after transplant is a major risk factor for late allograft failure (7). It is now believed that antibody-mediated rejection is the most common cause of late allograft failure (8,9). However, neither of the two phase 3 trials were able to adequately assess the effect of Envarsus XR on the development of donor specific antibodies and therefore, the efficacy of Envarsus XR in higher immunologic risk recipients is not known. Therefore, a comparative study of extended- and immediate-release tacrolimus in highly-sensitized recipients is warranted.
This is a randomized, open-label, controlled clinical trial designed to compare clinical outcomes after kidney transplantation using extended-release tacrolimus (Envarsus XR) versus immediate tacrolimus among highly-sensitized kidney transplant recipients. Twenty patients will be enrolled, with ten assigned to each study arm. Outcomes to be assessed include the incidence of biopsy-proven acute rejection at 12 months, the presence of de novo and pre-existing donor-specific HLA antibodies, estimated glomerular filtration rate, and the level of donor-derived cell-free DNA.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This is a randomized, open-label, controlled clinical trial designed to compare clinical outcomes after kidney transplantation using extended-release tacrolimus (Envarsus XR) versus immediate tacrolimus among highly-sensitized kidney transplant recipients. Outcomes to be assessed include the incidence of biopsy-proven acute rejection at 12 months, the presence of de novo and pre-existing donor-specific HLA antibodies, estimated glomerular filtration rate, and the level of donor-derived cell-free DNA.

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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
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 10 Jul 2024). 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 Biopsy-proven Acute Rejection (time frame: 12 months). 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 NCT04225988, which also lists 9 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.
