Olintatug (ADCT-901) is a highly specialized antibody-drug conjugate (ADC) targeting Kidney-Associated Antigen 1 (KAAG1). It comprises a humanized monoclonal antibody conjugated to a potent pyrrolobenzodiazepine (PBD) dimer cytotoxin via a cathepsin-cleavable linker. Olintatug specifically binds to KAAG1 on tumor cell surfaces, internalizes, and releases the PBD dimer, which induces lethal DNA interstrand cross-links, blocking cell division. It is investigated for KAAG1-expressing solid tumors, including ovarian and triple-negative breast cancers.
