|Kidney Transplant Rejection||Drug: MDR-103||Phase 2|
Currently, patients receiving a transplanted kidney are required to take life-long immunosuppressive medications to prevent rejection of the transplanted kidney. These medications carry substantial side effects. In addition, these medicines often do not completely control damage to the kidney from the recipients' immune system, ultimately causing the kidney to fail.
Medeor Therapeutics is developing a novel cell-based therapy to reprogram the past recipients' immune system to accept the transplanted kidney without the concurrent need for long term use of immunosuppressive drugs.
The purpose of the current Phase 2 study is to demonstrate the efficacy and safety of MDR-103 for the induction of transplant immune tolerance in a prospective, multicenter clinical trial. MDR-103 is intended to induce mixed lymphohematopoietic chimerism and donor specific immune tolerance in order to preserve transplant kidney function, avert transplant kidney rejection, and eliminate the cumulative and serious side effects associated with immunosuppressive drugs.

Experimental: Investigational Arm
A low-dose Total Lymphoid Irradiation (TLI) and anti-thymocyte globulin (ATG) combined with a single IV infusion of MDR-103 and standard anti-rejection medications in past recipients of HLA Zero-mismatch living donor kidney transplants.
MDR-103 Enriched CD34+ hematopoietic stem cells and defined dose of CD3+ T-cells
- Persistent Mixed Chimerism [ Time Frame: At 6 months post initiation of anti-thyroglobulin (ATG) conditioning therapy ]
The primary efficacy endpoint is the proportion of subjects achieving persistent mixed chimerism in MDR-103 treated recipients of past HLA zero-mismatch living donor kidney transplants.
Persistent Mixed Chimerism - is defined as at least 6 months of persistent WBC mixed chimerism consisting of at least 5% donor cells in whole blood or in at least one WBC lineage (CD3+ T cells, CD33+ myeloid cells, CD19+ B cells, and/or CD56+ NK cells).
