#73. The Triumph of Daraxonrasib

For decades, KRAS stood as oncology’s archetypal “undruggable” target—a powerful cancer driver with no obvious pocket for conventional medicines to grasp. This episode explores how molecular-glue drugs such as daraxonrasib overturn that assumption by recruiting cyclophilin A to form a synthetic complex around active RAS, physically blocking its growth signals. From the structural ingenuity behind this molecular trap to emerging clinical promise in pancreatic and other KRAS-driven cancers, the daraxonrasib FDA approval reveals a potential turning point in precision oncology—while examining resistance, patient selection, and what KRAS teaches us about drugging the seemingly impossible.
