Over the course of the year, and continuing into the latest scientific meetings, an extraordinary breadth of new antibody-drug conjugate (ADC) designs was reported, with innovations spanning targets, linkers, payloads, conjugation chemistries and overall architectures. Once defined by a simple “one target, one payload” model, the field is lately expanding into a more versatile and diverse therapeutic space.

Over the course of the year, and continuing into the latest scientific meetings, an extraordinary breadth of new antibody-drug conjugate (ADC) designs was reported, with innovations spanning targets, linkers, payloads, conjugation chemistries and overall architectures. Once defined by a simple “one target, one payload” model, the field is lately expanding into a more versatile and diverse therapeutic space.

Antibody-drug conjugates (ADCs) are a mature technology. The first ADC, Mylotarg, was initially approved in 2000, and there are now 14 approved agents in both leukemias and solid tumors. According to Clarivate’s Cortellis Drug Discovery & Intelligence, those drugs collectively accounted for $13.55 billion in sales in 2024 – a figure that Cortellis projects will rise to $16 billion in 2025.
