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.

Limitations and Caveats

Hide Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
Overall survival results are confounded by the fact that 85% of the participants initially randomized to placebo switched to open-label regorafenib.
