About TST005
TST005, is a bi-functional anti-PD-L1 and TGF-β trap fusion protein designed to simultaneously target two immuno-suppressive pathways, transforming growth factor β-(TGF-β) and programmed cell death ligand-1 (PD-L1), that are commonly used by cancer cells to evade the immune system. TST005 consists of a high affinity PD-L1 antibody fused with an engineered TGF-β Receptor Type II protein in its C-terminal. TST005 lacks FcR binding and has reduced risk of FcR mediated killing of PD-L1 expressing effector T cells. TST005's PD-L1 high binding activity and enhanced TGF-β trap stability enables the targeted delivery of TGF-β trap into PD-L1 expressing tumors, thereby minimizing off-target toxicities of systemic inhibition of TGF-β signaling. TST005 displayed potent activity in vitro in reversing TGF-β induced T-cell suppression. In multiple syngeneic tumor models, TST005 induced significant increase of CD8 T-cell infiltration into PD-L1 expressing tumors and displayed dose-dependent tumor growth inhibition. TST005 is well tolerated in non-human primates and displayed a linear PK profile. TST005 is a potential novel bi-functional immunotherapy candidate with improved therapeutic window.
