The FDA has granted a priority review designation to a new drug application (NDA) for avapritinib for the treatment of adult patients with PDGFRA exon 18–mutant gastrointestinal stromal tumors (GIST), regardless of prior therapy, as well as for patients with GIST in the fourth-line setting.1

The ongoing, international, open-label, randomized phase III VOYAGER trial (NCT03465722) is evaluating the safety and efficacy of avapritinib versus regorafenib (Stivarga) in patients with third- or fourth-line advanced GIST.
