Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
A total of 240 participants with metastatic and/or unresectable GIST whose disease had progressed despite prior treatments with at least imatinib and sunitinib were screened; 199 were randomized. Patients must have shown objective disease progression or intolerance to imatinib, as well as disease progression while on sunitinib treatment.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Participants were randomized in a 2:1 ratio to receive either regorafenib (133 patients) or placebo (66 patients). Randomization was stratified according 3rd vs. 4th line of therapy (at least 50% of patients were to be 3rd line), and geographical region (Asia vs.rest of world).

Reporting Groups
  Description
Regorafenib (Stivarga, BAY73-4506) Participants received Regorafenib (Stivarga) 160 mg (4 x 40 mg tablets) per os once daily, 3 weeks on therapy followed by 1 week off therapy to comprise a cycle of 4 weeks
Placebo First, Then Option of Open Label Regorafenib Treatment Double blind phase: participants received matching Placebo tablets per os once daily, 3 weeks on therapy followed by 1 week off therapy to comprise a cycle of 4 weeks. Open Label phase: participants on placebo who switched to Regorafenib, received Regorafenib 160 mg (4 x 40 mg tablets) per os once daily, 3 weeks on therapy followed by 1 week off therapy to comprise a cycle of 4 weeks.
