CAR-T Cell Therapy for Desensitization in Kidney Transplantation

This research study is for people who have been waiting for a kidney transplant for at least one year, and who have a cPRA of 99.5% or higher. Having a cPRA of 99.5% or higher means that your immune system would reject 99.5% of kidneys available for transplant. The study will test whether new products called Chimeric Antigen Receptor T Cells (CAR T Cells), when given with chemotherapy, is safe and will reduce cPRA.

The main study will last up to 2 years: Participants will have up to 30 clinic or hospital visits over a one-year period. If a transplant takes place, there will be 9 more visits after transplant. Long term follow up is required by the Food and Drug Administration (FDA) for 15 years after receiving CAR T cell.

The primary objective is to evaluate the safety and feasibility of administering CART BCMA + huCART-19 following lymphodepletion, including determination of optimal tolerated regimen (OTR) and/or recommended phase 2 regimen, according to the incidence of dose limiting toxicity (DLT) in highly sensitized patients awaiting kidney transplant.
