Treatment with anti-CD19 bispecific T-cell engager and CAR T therapies can lead to T-cell exhaustion and treatment failure. Novartis AG’s first-in-class anti-CD19, anti-CD3 and anti-CD2 IgG-like trispecific antibody PIT-565, which engages CD19+ on tumor cells, and CD3 (TCR signaling component) and CD2 (a costimulatory receptor) on T cells simultaneously to redirect T-cell cytotoxicity toward CD19-positive malignant B cells, has been designed to avoid T-cell exhaustion.
