Tailored Linker Chemistries for the Efficient and Selective Activation of ADCs with KSPi Payloads. | LitMetric

AI Article Synopsis

Article Abstract

Several antibody-drug conjugates (ADCs) have failed to achieve a sufficiently large therapeutic window in patients due to toxicity induced by unspecific payload release in the circulation or ADC uptake into healthy organs. Herein, we describe the successful engineering of ADCs consisting of novel linkers, which are efficiently and selectively cleaved by the tumor-associated protease legumain. ADCs generated via this approach demonstrate high potency and a preferential activation in tumors compared to healthy tissue, thus providing an additional level of safety. A remarkable tolerance of legumain for different linker peptides, including those with just a single asparagine residue, together with a modifier of the physicochemical metabolite profile, proves the broad applicability of this approach for a tailored design of ADCs.
