For decades, a pancreatic cancer diagnosis was among the most devastating words a patient could hear from their physician. The five-year survival rate for metastatic pancreatic cancer — cancer that has spread to other organs by the time it is caught — has historically hovered around 3%. Standard second-line chemotherapy for patients whose cancer had stopped responding to first-line treatment offered a median overall survival of just 6.7 months. These were not numbers that inspired hope. They were numbers that ended conversations about the future and began conversations about end-of-life planning.
That calculus may be changing. In one of the most significant oncology results of the decade, Revolution Medicines presented Phase 3 trial data for daraxonrasib on May 31, 2026 at the American Society of Clinical Oncology annual meeting in Chicago — the most important cancer research gathering in the world. The results were extraordinary: compared to standard chemotherapy, daraxonrasib nearly doubled overall survival for metastatic pancreatic cancer patients who had already received prior treatment, extending median overall survival from 6.7 months to 13.2 months. It reduced the risk of death by 60%. One-third of patients on the drug achieved at least a 20% reduction in tumor size. For a cancer that has been called "undruggable," this is a scientific watershed.
