Provided herein are trioxacarcin-antibody drug conjugates of Formula (I): and pharmaceutically acceptable salts thereof, wherein R7 is -L-B, wherein L is a linking group, and B is an antibody or antibody fragment. Also provided are methods of preparing the antibody-drug conjugates, pharmaceutically acceptable compositions thereof, and methods of their use and treatment. Further provided are precursors to the trioxacarcin- antibody drug conjugates (e.g., compounds of Formula (II), novel trioxacarcins without an antibody conjugated thereto), pharmaceutical compositions thereof, and methods of their use and treatment.
