The U.S. Food and Drug Administration today granted accelerated approval to Vitrakvi (larotrectinib), a treatment for adult and pediatric patients whose cancers have a specific genetic feature (biomarker). This is the second time the agency has approved a cancer treatment based on a common biomarker across different types of tumors rather than the location in the body where the tumor originated. The approval marks a new paradigm in the development of cancer drugs that are “tissue agnostic.”
