Evaluation of Anti-rejection Drug, Tacrolimus, in African-Americans With Kidney Transplant
Evaluation of Early Dose Escalation Using Extended-Release Tacrolimus (Envarsus XR®) to Reduce Acute Rejection and Donor Specific Antibodies in African American Renal Transplant Recipients
Forrás: ClinicalTrials.gov · Utoljára frissítve: 2025. márc. 14.
Rövid összefoglaló (regiszter, angolul)
In spite of conventional immunosuppression with lymphocyte-depleting induction followed by tacrolimus- and mycophenolate-based regimens, African American (AA) renal transplant recipients experience higher rates of acute rejection (AR), donor specific antibodies (DSA), and graft failure. Envarsus Extended-Release (XR)® (ENV) is a novel extended-release formulation of tacrolimus with a favorable pharmacokinetic profile, even in the setting of CYP3A5*1 allele (rapid metabolizers). The investigator will evaluate the safety and efficacy of early dose escalation with ENV in AA recipients. The study hypothesis is that higher tacrolimus target concentrations may be achieved without typical dose-limiting toxicities, and this may ultimately result in lower incidence of early AR, DSA, and graft loss.

Laborértékek
- • Presence of a positive T- or B-cell flow cytometry allogeneic crossmatch
- Presence of pre-formed anti-human leukocyte antigen (HLA) donor-specific antibodies (DSAs)
- Recipient of an ABO-incompatible organ
- Receipt of a multi-organ or dual kidney transplant
- Receipt of pediatric en bloc deceased donor kidneys
- Receipt of deceased donor kidney with a kidney donor profile index (KDPI) greater than or equal to 85%
- Has undergone desensitization, or received antibody removal, anti-B-cell, or anti-plasma cell therapy in the 90 days preceding the transplant
- Planned initiation of antibody removal (i.e. plasmapheresis) within 7 days of the transplant procedure
- Positive test for latent tuberculosis (TB) and has not previously received adequate anti-microbial therapy or would require TB prophylaxis after transplant
- Uncontrolled concomitant infection that would not allow for targeting escalated tacrolimus trough concentrations, as deemed by prescriber

- Current malignancy
- Use of an investigational study in the 30 days prior to the transplant procedure
