After decades of frustration, efforts to develop antibodies that can ferry drugs into cancer cells — and minimize damage to healthy tissue — are gathering steam. The next generation of these ‘weaponized antibody’ therapies, called antibody–drug conjugates, is working its way through clinical trials. The concept that underlies these drugs is simple: repurposing an antibody as a vehicle to deliver a toxic drug into a cancer cell.
