A Phase 2 Prospective, Multi-center, Open-label Trial to Assess the Safety and Efficacy of Cellular Immunotherapy With MDR-103 for Induction of Mixed Chimerism and Immune Tolerance in Past Recipients of HLA Zero-mismatch, Living Donor Kidney Transplants

The primary objective of this study is to demonstrate the safety and efficacy of cellular
immunotherapy with MDR-103 for induction of functional immune tolerance in past recipients of
human leukocyte antigen (HLA)-matched, living donor kidney transplants.

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.

Inclusion Criteria:
