The present disclosure provides antibody-drug conjugate (ADC) structures, which include a camptothecine or a camptothecine derivative linked to a polypeptide (e.g., an antibody) through a linker. The disclosure also encompasses compounds and methods for production of such conjugates, as well as methods of using the conjugates.

Camptothecine antibody-drug conjugates and methods of use thereof

The present disclosure provides antibody-drug conjugate structures, which include a cleavable linker that links the antibody to the drug and has a first enzymatically cleavable moiety and a second enzymatically cleavable moiety which includes a glycoside selected from a galactoside, a glucoside, a mannoside, a fucoside, O-GlcNAc, and O-GalNAc. The disclosure also encompasses compounds and methods for production of such conjugates, as well as methods of using the conjugates.

Glycoside dual-cleavage linkers for antibody-drug conjugates

The present disclosure provides antibodies specific for Mucin 1. Nucleic acids that encode one or both of the variable chains of an antibody of the present disclosure are also provided, as are cells that include such nucleic acids. Also provided are compositions that include the antibodies of the present disclosure, including in some instances, pharmaceutical compositions. Methods of making and using the antibodies of the present disclosure are also provided. In certain aspects, provided are methods that include administering to an individual having a cell proliferative disorder a therapeutically effective amount of an antibody of the present disclosure, where the antibody is administered to the individual to enhance an immune response, e.g., a T cell response, to abnormally proliferating cells of the cell proliferative disorder. The antibodies are also useful in various diagnostic, and monitoring applications, which are also provided.
