Anti-CD20 TriCAR (Rituximab) (28ζ), pCDCAR1 (TriCAR-Z159)

The anti-CD20 TriCAR is a novel chimeric antigen receptor (CAR) constructed for the engineering of T cells to target Human CD20.More specifically, the TriCAR is a CAR-T with unique TriTE (Tri-functional T cell Engager) construct. In general, TriTE is a fusion protein with unique functions including T cell engagement, T cell stimulation, and check point blocking. It consists of five components, including R1(antigen binding domain), R2 (anti-CD3, here refer to the CD28/4-1BB-CD3ζ intracellular constimulatory domain), R3 & R4(IL15 binding domain), and R5 (PD1 for binding to PD-L1). Therefore, the TriCAR contains an anti-antigen scFv, a PD-L1 blocker, and a cytokine complex, enabling the TriCAR/SILK to simultaneously targeting the antigen-specific cancer cells, blocking the inhibitory PD-L1 signal and stimulating innate T/NK cell activation and expansion, thus make it a tri-functional CAR (Tri-CAR).

  • TriCAR is a CAR-T with unique TriTE (Tri-functional T cell Engager) construct. TriTE is a fusion protein with unique functions including T cell engagement, T cell stimulation, and check point blocking. It consists of five components, including R1(antigen binding domain), R2 (CD28/4-1BB-CD3ζ intracellular constimulatory domain), R3 & R4(IL15 binding domain), and R5 (PD1 for binding to PD-L1). The R1 component binds to a specific cancer antigen on T cells , and and at the same time, the IL15 and PD1 (R4&R5) domains improve the in-tumor micro-environment for solid tumor immunotherapies.
