Overview
**TCX-201 + monomethyl auristatin E** is a preclinical antibody-drug conjugate developed by Tacalyx for solid tumors. It consists of the fully humanized TACA-targeting antibody TCX-201 conjugated through a cleavable linker to the cytotoxic microtubule-disrupting payload monomethyl auristatin E, with a reported drug-to-antibody ratio of 4. The precise tumor-associated carbohydrate antigen target has not been publicly disclosed. In preclinical pancreatic and colorectal cancer models, the MMAE conjugate showed potent target-dependent cell killing and antitumor activity following intravenous dosing.
