Inducing Graft Tolerance in HLA Haplotype Matched Related and 3 Ag Matched Unrelated Living Donor Kidney Transplantation

Trial ID or NCT#



recruiting iconRECRUITING


This research study is to determine if donor blood stem cells given after living, related, HLA antigen (Ag) haplotype match or living, unrelated donor kidney transplantation. Minimal HLA antigen matching will include matching of 2 HLA antigens that can be either HLA A, B, and /or DR. This research will change the immune system such that immunosuppressive drugs can be completely withdrawn or reduced to minimal dose without kidney rejection.

Official Title

Induction of Immune Tolerance by Total Lymphoid Irradiation, Anti-Thymocyte Globulin and Purified Donor CD34+ and T Cell Transfusion in HLA Haplotype Matched Related and 3 Antigen HLA Matched Unrelated Living Donor Kidney Transplantation
