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.
