Suzhou CStone Pharma filed an NDA in Taiwan for avapritinib, a precision therapy for gastrointestinal stromal tumors (GIST). The candidate is indicated for adult patients with unresectable or metastatic GIST harboring a platelet-derived growth factor receptor alpha (PDGFRA) exon 18 mutation, including PDGFRA D842V mutations.
