RESUMO
Introduction: Antibody-Drug Conjugates (ADCs) are becoming increasingly important weapons in the fight against cancer, as evidenced by the growing number of approved products. The complex nature of an ADC means that there is a vast array of choices to consider in the design of such drugs.Areas covered: We provide an overview of developments in each facet of ADC structure: the antibody, linker, and payload. Looking at the current clinical landscape, we discuss trends that have led to the evolution of ADC design.Expert opinion:Following a history of setbacks and high discontinuation rates, the understanding of the ADC field has grown. If developers can obtain a firm grasp of the structure-function relationship of their molecule, we expect the advances in ADC design to translate to improved clinical success. Moreover, the breadth of ADC applications will continue to expand to target new indications with novel targets and payloads.
