ESG401 is composed of a humanized anti-Trop2 IgG1 monoclonal antibody (mAb) conjugated to a topoisomerase I inhibitor SN38 via a proprietary stable covalent linker with a drug antibody ratio (DAR) of 8.
A166 is an antibody-drug conjugate (ADC) composed of an anti-HER2 antibody conjugated to Duostatin-5, a novel anti-microtubule Auristatin derivative, via a proprietary stable covalent linker.
A166, a third-generation antibody-drug conjugate with tubulin inhibitor Duo-5 toxin, cleavable linker and site-specific K-Lock conjugation chemistry, demonstrated antitumor activity with meaningful responses in heavily pretreated subjects with HER2-positive breast cancer.
ADCs developed under this collaboration combine Levena’s linker and cytotoxic payload chemistry expertise along with Navrogen’s cancer-targeting antibodies.
