On Jan. 9, 2020, the U.S. Food and Drug Administration (FDA) announced approval of avapritinib (Ayvakit) for the treatment of adults with unresectable or metastatic gastrointestinal stromal tumor (GIST) – harboring a platelet-derived growth factor receptor alpha (PDGFRA) exon 18 mutation. This approval includes GIST that harbors a PDGFRA D842V mutation, which is the most common exon 18 mutation. Ayvakit is a kinase inhibitor, meaning it blocks a type of enzyme called a kinase and helps keep the cancer cells from growing.
