TxCell develops innovative, personalized cellular immunotherapies using regulatory T cells (Treg) to treat severe chronic inflammatory and autoimmune diseases. TxCell is developing two proprietary technology platforms, ASTrIA and ENTrIA.
ASTrIA is composed of autologous antigen specific Type 1 Regulatory T cells (Ag-Treg). It uses the natural immuno-modulatory properties of Ag-Treg cells. Patient's purified blood cells are educated ex-vivo to recognize a chosen antigen.
ENTrIA is composed of Chimeric Antigen Receptor (CAR) engineered FoxP3+ Regulatory T cells (CAR-Treg). After their isolation from the blood of patients, FoxP3+ Treg cells are genetically modified by transduction with a CAR.
TxCell's lead drug-candidate Ovasave® originates from the ASTrIA platform. A phase IIb placebo-controlled study has been initiated in refractory Crohn's Disease patients. This follows a phase I/IIa study in the same patient population, which has been successfully completed and reported positive clinical efficacy and good tolerability (link1 & link2).
