Definition

A preparation of autologous programmed cell death protein 1 (PD-1; PDCD1; CD279)-positive T lymphocytes transduced with a lentivirus expressing a chimeric antigen receptor (CAR) specific for the tumor-associated antigen (TAA) trophoblast cell surface protein 2 (trophoblast antigen 2; tumor-associated calcium signal transducer 2; TROP2; TROP-2; TACSTD2; GA733-1; M1S1), with potential immunostimulating and antineoplastic activities. Upon administration, autologous TROP2-CAR-transduced PD-1-positive T cells T60c target, bind to and induce selective cytotoxicity in TROP2-expressing tumor cells. TROP2 is a transmembrane protein overexpressed in various tumors. Its expression is associated with enhanced tumor aggressiveness, metastasis, drug resistance and increased tumor cell survival.
