Bispecific Antibody Fusion Protein

Dr. Hui Zhou, Senior Vice President of Innovent, stated: "IBI363, as a first-in-class molecule, represents Innovent's continuous innovation and advancement in the immunotherapy field. Starting from molecular design, the unique approach of α bias with β and γ attenuated were creatively adopted, which greatly improved the therapeutic window of IL-2. Meanwhile, through the specific traction of PD-1, tumor-specific T cells expressing both PD-1 and CD25 can be selectively stimulated and amplified, thus exerting anti-tumor effects. IBI363 has demonstrated excellent druggability with antibody-like pharmacokinetics (IgG-like PK) and low immunogenicity.
