PEGylation of Dipeptide Linker Improves Therapeutic Index and Pharmacokinetics of Antibody-Drug Conjugates.

Bioconjug Chem

January 2025

Biotherapeutics Discovery Research Center, Shanghai Institute of Materia Medica, Chinese Academy of Sciences, Shanghai 201203, China.

Hydrophobic payloads incorporated into antibody-drug conjugates (ADCs) typically are superior to hydrophilic ones in tumor penetration and "bystander killing" upon release from ADCs. However, they are prone to aggregation and accelerated plasma clearance, which lead to reduced efficacies and increased toxicities of ADC molecules. Shielding the hydrophobicity of payloads by incorporating polyethylene glycol (PEG) elements or sugar groups into the ADC linkers has emerged as a viable alternative to directly adopting hydrophilic payloads.
