zamtocabtagene autoleucel

A preparation of autologous CD4/CD8 enriched T lymphocytes engineered to express pLTG1497, a tandem chimeric antigen receptor (CAR) specific for the two tumor-associated antigens (TAAs) cluster of differentiation 19 (CD19) and CD20, with potential immunostimulating and antineoplastic activities. Upon administration, zamtocabtagene autoleucel target and bind to CD19- and CD20-expressing tumor B cells. This induces selective toxicity in tumor B-cells expressing these TAAs. Both CD19 and CD20 are B-cell-specific cell surface antigens overexpressed in B-cell lineage malignancies. Targeting both CD19 and CD20 may prevent tumor cell antigen escape and relapse.
