Cellular Immunotherapy in Recipients of HLA-matched, Living Donor Kidney Transplants

Phase 3
Completed
Conditions
Kidney Transplant Rejection
Interventions
Biological: MDR-101
Registration Number
NCT03363945
Lead Sponsor
Medeor Therapeutics, Inc.
Brief Summary

The primary objective of this study is to demonstrate the safety and efficacy of cellular immunotherapy with MDR-101 for induction of functional immune tolerance in recipients of human leukocyte antigen (HLA)-matched, living donor kidney transplants.

Detailed Description

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 recipients' immune system to accept a transplanted kidney without the need for long term use of immunosuppression drugs.

The purpose of the current Phase 3 study is to demonstrate the efficacy and safety of MDR-101 for the induction of transplant immune tolerance in a prospective, randomized, multicenter clinical trial. MDR-101 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.

Primary Outcome Measures
NameTimeMethod
Functional immune tolerance defined asUp to 36 months post-kidney transplant

* Achievement of the required duration of persistent donor mixed chimerism to permit calcineurin inhibitor immunosuppressive withdrawal beginning at 6-7 months post-kidney transplant surgery, and

* Successful withdrawal from all immunosuppressives by at least 12 months post-kidney transplant surgery, and

* Subsequent successful maintenance off all immunosuppressive drugs for at least 24 additional months (out to at least 36 months post-kidney transplant surgery) without biopsy-proven acute rejection, de novo Donor Specific Antibody, transplant kidney loss, or subject death. Loss to follow-up will be adjudicated as a failure in intent-to-treat analysis.
