Recruiting PHASE1 Kidney Transplant

New treatment option for Kidney Transplant

Official title CAR-T Cell Therapy for Desensitization in Kidney Transplantation

ClinicalTrials.gov ID: NCT06056102

What this study is testing

What is Cyclophosphamide?

Cyclophosphamide is an investigational medicine, given as an once-daily infusion into a vein, being studied as a potential treatment for kidney transplant.

Also referred to as Cytoxan.

Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
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.
  • Phase 1: an early, usually small safety study
