TRACT Therapeutics, Inc., a biotechnology company developing personalized regulatory T-cell (Treg) therapy, announced today that it received Food and Drug Administration (FDA) approval to initiate a Phase 2 clinical trial to investigate the efficacy and safety of its novel therapy for kidney transplant recipients. The therapeutic approach, utilizing a patient’s own cells, expanded in the laboratory and infused back to the patient after an organ transplant, shows promise in restoring immune balance so the body will accept the foreign organ instead of rejecting it. Current standard of care practices for transplant patients to prevent rejection requires the lifetime use of toxic medications which weaken the immune system causing life-threatening effects and eventual rejection of the organ in approximately 50% of the patients receiving a transplant. A National Institute of Health study in the U.S. recently revealed that organ recipients have a high risk of developing 32 different types of cancer. TRACT’s innovative approach aims to change the standard treatment for transplant recipients by reducing or eliminating the lifelong use of immunosuppressive drug therapy.

The Phase 2 study of 120 subjects will evaluate the efficacy and safety of a single Treg infusion in kidney transplant recipients and is projected to initiate enrollment in a few months. “The limitations of drug-based immunosuppression have significantly increased interest in the use of regulatory T-cells to restore balance to the immune system and avoid transplant rejection,” stated Joseph R Leventhal, MD, PhD, Director of Kidney and Pancreas Transplantation at Northwestern University Feinberg School of Medicine.

Gretchen S Johnson, President and CEO of TRACT Therapeutics, commented, “We are pleased to continue on our path toward approval and commercialization of this novel Treg therapy with the goal of greatly enhancing the lives of transplant patients around the world.”
