Treatment Advances in Gastrointestinal Stromal Tumor: Margaret von Mehren, MD

The treatment of gastrointestinal stromal tumor (GIST), a rare tumor type with an estimated incidence of 3,300 to 6,000 new cases per year in the United States, has seen exciting advances this year, first with the FDA's approval of avapritinib for metastatic GIST with platelet-derived growth factor receptor alpha (PDGFRA) exon 18 mutations, and more recently with last month's approval of ripretinib for the later-line treatment of metastatic GIST. Margaret von Mehren, MD, principal investigator o...

Enhancing Treatment for Patients With GIST: Michael Heinrich, MD

Because gastrointestinal stromal tumor (GIST) has an estimated incidence of 3,300 to 6,000 new cases per year in the United States, comprising less than 1% of all gastrointestinal tumors, the rarity of this tumor type can make it more challenging for oncologists and other members of the cancer care team to stay up to date on the latest treatments. Michael C. Heinrich, MD, lead investigator of the phase 1 NAVIGATOR trial, recently spoke with i3 Health about the FDA's approval of avapritinib (Ayva...

Avapritinib for PDGFRA Exon 18-Mutated GIST: Michael Heinrich, MD

Up to 10% of patients with gastrointestinal stromal tumor (GIST) harbor platelet-derived growth factor receptor alpha (PDGFRA) exon 18 mutations, which have been linked to resistance to standard GIST therapies. The FDA's recent approval of avapritinib (AyvakitTM, Blueprint Medicines) for adults with unresectable or metastatic GIST with PDGFRA exon 18 mutations has given these patients a highly promising treatment option. In this interview, Michael C. Heinrich, MD, lead investigator of the phase ...
