Update Regarding TX200 (Kidney Transplant Rejection)
On March 22, 2022, Sangamo Therapeutics, Inc. (“Sangamo”) dosed the first patient in its Phase 1/2 STEADFAST clinical study evaluating TX200, a wholly-owned autologous Chimeric Antigen Receptor, or CAR, engineered regulatory T cell, or CAR-Treg, cell therapy product candidate for the prevention of immune-mediated rejection in HLA-A2 mismatched kidney transplantation from a living donor. An autologous cell therapy is made using cells from the same person as the recipient of the cells.
Sangamo designed TX200 with the potential to prevent kidney rejection by reducing local inflammation and promoting immunological tolerance to the graft. TX200 is composed of autologous Treg cells engineered to express an HLA-A2 CAR. TX200 cells are expected to localize to the graft and activate upon binding to the HLA-A2 antigen. Through their ability to regulate the immune system, TX200 cells may protect the graft from immune-mediated rejection and reduce or eliminate the need for lifelong treatment with immunosuppressants.
In the STEADFAST clinical study design, each patient undergoes a leukapheresis procedure to collect the patient’s white blood cells, after which the patient’s Treg cells are isolated and engineered and then cryopreserved. The patient subsequently undergoes transplantation surgery to receive a kidney from a living donor. Following a recovery period, the patient receives a personalized TX200 investigational cell therapy; dosing of patients occurs several months after patient enrollment.
Sangamo expects to dose a second patient in the STEADFAST study in the middle of 2022. In addition to TX200, Sangamo is developing CAR-Treg cell therapy candidates in preclinical studies, including for potential use in treating multiple sclerosis and inflammatory bowel disorders.
