Drug Development
HBM7020 is a BCMAxCD3 bispecific antibody (BsAb) developed using Harbour BioMed’s fully human HBICE bispecific antibody technology and Harbour Mice platform. The antibody works by targeting BCMA on cell surfaces and CD3 on T cells, effectively bridging target cells with T cells to activate T-cell-mediated killing.-Fineline Info & Tech
