Summary
This trial will study whether patients with a kidney transplant from a HLA-identical living donor can stop taking immunosuppressive drugs without damaging the transplanted kidney, by receiving hematopoietic stem cells from the same donor.
Who is the study for?
Adults over 18 with a well-functioning kidney transplant from an HLA-identical living donor can join. They must have good physical function, heart and liver health, no major post-transplant complications or rejection history, and stable kidney function. Women of childbearing age must use contraception.
What is being tested?
The trial tests if patients can stop taking anti-rejection drugs after receiving stem cells from their kidney donor. It includes a conditioning regimen with total lymphoid irradiation and rabbit anti-thymocyte globulin before the stem cell infusion.
What are the potential side effects?
Potential side effects include reactions to rabbit proteins, changes in blood counts due to radiation or rATG treatment, increased risk of infections, and possible organ inflammation related to the immune system's response.

Experimental Treatment
Group I: Immune tolerance in HLA-identical kidney transplant recipientExperimental Treatment1 Intervention
We seek to establish immunological tolerance in patients with a pre-existing, well- functioning kidney transplant from an HLA-identical donor. Patients will undergo conditioning with TLI and ATG, followed by infusion of hematopoietic stem cells from the same donor . We will evaluate whether recipients can be withdrawn from immunosuppressive drugs without compromising allograft function. At serial time points, graft function will be monitored, and chimerism will be measured. Weaning of tacrolimus will begin at 6 months, with a goal of drug discontinuation within 12 months if the following conditions are met: (1) chimerism (defined as ≥1% donor type cells among the T cells, B cells, NK cells, and granulocytes) is detectable for at least 180 days, (2) stable graft function (defined as eGFR \>30 mL/min and no greater than sustained 30% change over 3 months from baseline) without clinical rejection episodes is maintained, and (3) no evidence of graft vs. host disease (GVHD).
