Other Clinical Trial - Cellular Immunotherapy in Recipients of Human

Status Withdrawn

Clinical Trial Summary

The Phase 2 primary objective is to evaluate achievement of persistent mixed chimerism and withdrawal of at least one immunosuppression drug for a minimum of 6 months with no episodes of biopsy-proven acute rejection or transplant kidney loss induced by cellular immunotherapy with MDR-102 in recipients of 1, 2, or 3 out of 6 human leukocyte antigen (HLA)-mismatched, living donor kidney transplants. The Phase 3 primary objective is to evaluate achievement of induction of immune quiescence by cellular immunotherapy with MDR-102 in recipients of 1, 2, or 3 out of 6 HLA-mismatched, living donor kidney transplants. Immune quiescence is defined as remaining on maintenance immunosuppression monotherapy with Tac or CsA for 12 months or more after completion of anti-rejection immunosuppression drug therapy reduction with no episodes of biopsy-proven acute rejection, transplant kidney loss, or subject deat.

Clinical Trial 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 as personalized cellular immunotherapies to improve outcomes in organ transplant recipients. The purpose of the current Phase 2/3 study is to demonstrate the efficacy and safety of MDR-102 for the induction of immune quiescence in a prospective, randomized, open-label, multi-center clinical trial. MDR-102 is intended to induce mixed lymphohematopoietic chimerism and donor specific immune quiescence in order to preserve transplant kidney function, avert transplant kidney rejection, and reduce the cumulative and serious side effects associated with immunosuppression drugs. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
