Preclinical Antitumor Activity and Biodistribution of a Novel Anti-GCC Antibody–Drug Conjugate in Patient-derived Xenografts

Guanylyl cyclase C (GCC) is a unique therapeutic target with expression restricted to the apical side of epithelial cell tight junctions thought to be only accessible by intravenously administered agents on malignant tissues where GCC expression is aberrant. In this study, we sought to evaluate the therapeutic potential of a second-generation investigational antibody–dug conjugate (ADC), TAK-164, comprised of a human anti-GCC mAb conjugated via...
