Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Male or female untreated participants, who were at least 18 years of age, with metastatic and/or unresectable, measurable predominantly clear cell renal cell cancer (RCC) histologically or cytologically documented could participate in this study at 18 centers in 6 countries.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Of 64 enrolled participants, 49 received study medication, and 15 were screen failures due to protocol violation (12 participants), withdrawal of consent (1 participant), adverse event (2 participants).

Reporting Groups
  Description
Regorafenib (Stivarga, BAY73-4506) Participants received Regorafenib 160 mg per os (po) every day (qd) for 3 weeks on 1 week off of every 4 week cycle

[1] The ECOG PS ranged from Grades 0 to 5 (death). Grade 0 (fully active, able to carry on all pre-diseases performance without restriction) and Grade 1 (restricted in physically strenuous activity but ambulatory and able to carry out work of a light or sedentary nature) were inclusion criteria.
[2] The Motzer score (high/poor risk, intermediate risk, low risk) is based on the number of the following poor prognostic features a participant possessed: ECOG >2, serum lactate dehydrogenase concentration > 1.5 times the upper limit of normal, hemoglobin < lower limit of normal, corrected calcium concentration > 10 mg/dl, and absence of prior nephrectomy. Participants who had none of these features = low risk; participants with 1 or 2 of these features = intermediate risk; participants with 3 or more of these features = high/poor risk and were excluded from participating in the study.

Measure Type Secondary
Measure Title Progression-free Survival (PFS)
Measure Description PFS was calculated as time from first date of receiving study drug until date of first observed disease progression (PD) (radiological or clinical, whichever was earlier) or death due to any cause, if death occurred before PD was documented. The actual date of tumor assessments (i.e., date on which radiological procedure was performed, rather than scheduled date) was used for this calculation to determine both the event date and censoring date. Patients without PD or death at time of analysis were censored at last date of tumor evaluation.
Time Frame From start of treatment of the first participant until database cut-off approximately 13 months later (13May2008 - 31May2009). Assessed every 8 weeks for 6 months, then every 12 weeks
