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).
Phase 3 trials are pivotal studies with large patient populations (hundreds to thousands) designed to prove efficacy and safety for FDA submission. A successful Phase 3 readout is typically the last major hurdle before a New Drug Application (NDA) or BLA filing.
Enrollment is complete. The trial is in its follow-up or data collection phase — a readout may occur on or near the primary completion date.
Deciphera Pharmaceuticals (DCPH) is the sponsoring company for this trial. BiotechSign currently grades this company D (40/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
