Recruiting PHASE1 Kidney Transplantation

New treatment option for Kidney Transplantation

Official title Eight-Treg Study:Trial of Adoptive Immunotherapy With Autologous ex Vivo Expanded Regulatory CD8+ T Cells in Living Donor Kidney Transplant Recipients

ClinicalTrials.gov ID: NCT06777719

What this study is testing

What is Eight Treg?

Eight Treg is an investigational medicine, given as an infusion into a vein, being studied as a potential treatment for kidney transplantation.

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
The only curative treatment for end-stage renal disease is through kidney transplantation. Solid organ transplants success had been made possible by the development of Immunosuppressive (IS) drugs.
