[VIRTUAL] Immunotherapy directed to tumor antigen by multi-specific antibody
(AACR 2021)
- "Though some agents, Trastuzumab, Ramucirumab, Pembrolizumab as well as Apatinib has been approved for clinical use, chemotherapy is still the first line treatment, demonstrating the need for more effective treatment with less toxicity.For the purpose of enhancing therapeutic index, we designed a bispecific antibody Q-1802 to target checkpoint inhibitors to Claudin 18.2, a membrane protein positive for most gastric tumor cells. In preliminary toxicology study, no animals in the dose exploration experiment showed abnormality in the body weight, body temperature, hematology examination etc in each dose group. Further studies are on-going to explore details of mechanism for efficacy toxicity and PK for this compound."
