About GB261 (CD20/CD3，BsAb)
GB261 is the first T-Cell Engager with ultra-low affinity to bind CD3 and has Fc-enabled functions (ADCC and CDC). GB261 significantly inhibits rituximab-resistant cancer cell proliferation in both in vitro assays and in vivo models. Thus, GB261 is a highly potent bispecific therapeutic antibody for B cell malignancies. It has potential to be a better and safer T-cell engager with competitive advantages over other CD3/CD20 agents.
