FDA Approves Avapritinib for GIST Subset
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.
