  • Publication number: 20230032465
    Abstract: An improved antibody-drug conjugate (ADC) targeting CD276-positive tumors is described. The ADC includes a CD276-specific IgG1 antibody having a heavy chain modified to prevent interaction of its Fc domain with endogenous Fc receptors and to introduce a cysteine for site-specific conjugation of the drug. The CD276-specific ADC is capable of potently eradicating CD276-positive tumors in several animal models.
