This infographic titled "Antibody-drug conjugates for cancer treatment" explains how ADCs act as "magic bullets" by combining an antibody, a linker, and a cytotoxic drug to target cancer cells. A timeline spans from Paul Ehrlich’s 1910 concept to 2025, noting that 25 ADCs are now approved globally. Diagrams illustrate ADCs binding to cancer cell antigens, entering the cell, and releasing drugs to disrupt DNA or microtubules. Future trends include bispecific ADCs and dual-drug conjugates.

Today (4 Feb) is World Cancer Day. Analysts estimate that there will be 30.5 million new cancer cases diagnosed yearly by 2050, with a projected 18.6 million annual deaths. However, our ability to use medicines to target more effectively is improving, and antibody–drug conjugates are an increasingly effective tool in combating cancers. This graphic explains what they are, how they work, and how they might improve in the future.

This graphic was funded by a grant from the British Society for the History of Science.
