EFFICACY OF ANTI-TROP-2-SN-38 ANTIBODY DRUG CONJUGATES FOR THERAPY OF TUMORS RELAPSED/REFRACTORY TO CHECKPOINT INHIBITORS

摘要

The present invention relates to therapeutic ADCs comprising SN-38 attached to an anti-Trop-2 antibody or antigen-binding antibody fragment, more particularly sacituzumab govitecan. The ADC is administered to a subject with a Trop-2 positive cancer that is resistant to or relapsed from prior treatment with a checkpoint inhibitor. The therapy is effective to treat cancers that are resistant to checkpoint inhibitors.
