What was measured

OS was defined as the time from the date of randomization until death due to any cause.

Analysis population: All patient (AP) Intent to Treat (ITT) Population is defined as all patients who are randomized. Patients in this population will be analyzed according to the treatment they were scheduled to receive.

Groups in this outcome

Ripretinib

Ripretinib (150 mg) once a day continuous dosing for 6-week (42 days) cycles

Sunitinib

Sunitinib (50 mg) once a day in 6-week (42 days) cycles with 4 weeks continuous dosing followed by 2 week break.

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
