Brief Summary:
An open-label study to assess the safety, efficacy, and tolerance of FCRx cell therapy in adult recipients within 12 months after kidney transplantation from a living donor.

Condition or disease Intervention/treatment Phase
Kidney Failure Biological: Enriched Hematopoietic Stem Cell Infusion Phase 2

Detailed Description:
Research study which involves the use of a combination of an Enriched Hematopoietic Stem Cell Infusion (stem cells, produced by the bone marrow, generate the cells that form the blood elements, help fight infection and assist in clotting) and kidney transplantation from the same donor to try to avoid the need for long-term anti-rejection drug therapy. The desired result of this study is to allow the body to develop "tolerance" to the transplanted kidney. Tolerance means that the body would see the transplanted kidney as part of the patient and not try to get rid of, or reject it. To prevent rejection, drugs called immunosuppressive agents must be taken on a daily basis. The purpose of this study is to determine if this procedure is safe and to try to substantially reduce or even eliminate the need for anti-rejection medications.

Ages Eligible for Study:   18 Years to 65 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Patient must be between the ages of 18 and 65 years and meet the institution's criteria for renal transplantation for end-organ failure
  • Meets the transplant criteria by the study site and both the recipient and donor have been accepted as candidates for standard of care living kidney donation and transplantation
  • Patient is receiving a renal transplant only
  • The crossmatch is negative between donor and recipient. An initial crossmatch will be performed prior to stem cell mobilization to determine if subject can proceed with the apheresis.
  • Potential recipients who are women of child bearing potential must have a negative pregnancy test (urine test is acceptable) within 48 hours prior to receiving Granulocyte colony-stimulating factor (G-CSF) and agree to use reliable contraception for 1 year following FCRx infusion
  • Potential donors who are women of child bearing potential must have a negative pregnancy test (urine test is acceptable) within 48 hours prior to receiving G-CSF
  • No evidence of donor-specific antibody presently or historically
  • Panel Reactive Antibody (PRA) less than or equal to 20

Note: The subjects do not need to be local residents in order to be eligible for this trial, but must be willing to reside in the area, or within a four-hour drive, for the first month of the protocol so that they can be monitored closely in the early post-transplant period.

Exclusion Criteria:

  • Clinically active bacterial, fungal, viral or parasitic infection
  • Pregnancy
  • Clinical or serologic evidence of viral infection which would preclude the recipient from receiving a kidney transplant or FCRx infusion
  • Previous radiation therapy at a dose which would preclude Total Body Irradiation (TBI)
  • Positive crossmatch between donor and recipient
  • Evidence for immunologic memory against donor
  • Body Mass Index (BMI) >35 or <18
  • Positive serologies for Hepatitis B Virus (HBV), Hepatitis C Virus (HCV), human immunodeficiency virus (HIV)
