About TJ-CD4B/ABL111

TJ-CD4B/ABL111 was developed in cooperation with ABL Bio of South Korea (Kosdaq stock code: 298380) in South Korea's GEM market.
TJ-CD4B/ABL111 is a highly specific expression that targets multiple cancers, especially gastric cancer and pancreatic cancer.
The innovative bispecific antibody of the tumor antigen claudin 18 splice body 2 (Claudin 18.
2) and the T cell costimulatory molecule 4-1BB
.
TJ-CD4B's unique 4-1BB binding epitope allows it to activate T cells only when it binds to Claudin 18.
2
.
This feature avoids liver toxicity caused by excessive activation of T cells due to the widespread expression of 4-1BB and reduces the risk of systemic immune response
.

About TJ-L14B/ABL503

TJ-L14B/ABL503 is a highly differentiated bispecific antibody based on PD-L1 developed by Tianjing Bio and ABL Bio (Kosdaq stock code: 298380), which can block PD- The L1 signal stimulates the 4-1BB signal and activates T cells to produce an anti-tumor synergistic effect, thereby transforming a "cold" tumor with a weak immune response into a "hot" tumor that is sensitive to PD-(L)1 treatment
.
The double antibody was developed on ABL Bio's "Grabody-T" antibody engineering technology platform, so that it activates 4-1BB only when tumor cells express PD-L1, which can significantly reduce off-target effects
.
Pre-clinical studies have shown that compared to PD-L1 antibody or 4-1BB antibody single-drug or combination therapy, TJ-L14B/ABL503 as a dual-antibody drug exhibits better anti-tumor activity
.
