Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A randomized controlled study to evaluate the safety, efficacy, and overall benefit of FCR001 cell therapy in de novo living donor renal transplantation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The purpose of this randomized (2:1) controlled study is to evaluate the safety, efficacy and overall benefit of FCR001 cell therapy in first or second de novo living donor renal transplantation relative to a standard-of-care control immunosuppression regimen of antibody induction, tacrolimus, mycophenolate, and corticosteroids.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

FCR001

FCR001 is a cryopreserved allogeneic stem cell therapy derived from mobilized peripheral blood of the kidney donor that is delivered as a single dose with a non- myeloablative conditioning regimen. FCR001 contains the donor's CD34+ cells, facilitating cells, and αβ T cells.

Group Type EXPERIMENTAL

FCR001

Intervention Type BIOLOGICAL

FCR001 is a cryopreserved allogeneic stem cell therapy derived from mobilized peripheral blood of the kidney donor that is delivered as a single dose with a non- myeloablative conditioning regimen. FCR001 contains the donor's CD34+ cells, facilitating cells, and αβ T cells.

Control

Standard induction therapy followed by a maintenance regimen of tacrolimus, mycophenolate, and +/- corticosteroids after kidney transplant.

Control donors are not followed beyond randomization.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Recipient age ≥18 years.
* Donor age ≥18 and ≤60 years at time of signing informed consent.
* Recipients of a first or second living donor kidney transplant
* Donor willing to undergo mobilization, apheresis and 12-month safety follow-up and meet all local standard eligibility criteria to donate stem cells for allogeneic transplantation.
* Recipient meets all local standard eligibility criteria for allogeneic stem cell transplant.
* Donors must be deemed eligible as per the requirements of 21CFR1271.

Exclusion Criteria

* Recipient and donor who are identical twins.
* Recipient or donor with history of malignancy or premalignant syndrome (e.g., myelodysplastic syndrome, monoclonal gammopathy of renal significance \[MGRS\], monoclonal gammopathy of unknown significance \[MGUS\]) of any organ system (other than localized basal cell carcinoma of the skin or in-situ cervical cancer), treated or untreated, within the past 5 years, regardless of whether there is evidence of local recurrence or metastases.
* Recipient or donor with known bone marrow aplasia.


* Multi-organ or stem cell transplant recipient.
* Calculated panel reactive antibodies \>80%.
* Recipient is blood type ABO incompatible with donor.
* Presence of donor-specific antibodies (DSA) (positive result) at any time pre-transplant.
* Recipient who is human immunodeficiency virus (HIV), hepatitis B surface antigen (HBsAg) or hepatitis C virus (HCV) positive.
* Recipient with any baseline condition requiring or anticipated will require chronic or intermittent use of systemic steroids or other IS (eg, autoimmune disease, asthma) throughout the course of the study.
* Recipient with a BMI \< 18 or \> 35 kg/m2.
* Recipient requiring systemic anticoagulation, (eg, for hyper-coagulation disorders, deep vein thrombosis, atrial fibrillation) that cannot be temporarily interrupted which would preclude renal biopsy.


* Biologically unrelated (i.e., no genetic relationship) female donor transplant to male recipient.
