2. Histologic diagnosis of GIST and must be able to provide an archival tumor tissue sample, otherwise, a fresh biopsy is required.
3. Molecular pathology report must be available. If molecular pathology report is not available or insufficient, an archival tumor tissue sample or fresh biopsy is required for mutation status confirmation by the central laboratory prior to randomization.
4. Patients must have progressed on imatinib or have documented intolerance to imatinib.
5. Eastern Cooperative Oncology Group (ECOG) Performance Score (PS) of = 2 at screening.
6. Female patients of childbearing potential must have a negative serum beta-human chorionic gonadotropin (ß-hCG) pregnancy test at screening and negative pregnancy test at Cycle 1 Day 1 prior to the first dose of study drug.

Summary
Brief summary
This is a 2-arm, randomized, open-label, international, multicenter study comparing the efficacy of ripretinib to sunitinib in GIST patients who progressed on or were intolerant to first-line anticancer treatment with imatinib. Approximately 426 patients will be randomized in a 1:1 ratio to ripretinib 150 mg once daily (continuous dosing for 6 week cycles) or sunitinib 50 mg once daily (6 week cycles, 4 weeks on, 2 weeks off).
