This is a uncontrolled, open-label, non-randomized Phase II study of oral BAY73-4506 to evaluate the response rate of BAY73-4506 in previously untreated patients with metastatic or unresectable renal cell cancer (RCC).
The final analysis of efficacy will be performed after last patient has been treated for at least 6 months. Additional periodic safety and efficacy data reviews will be performed for any patients continuing to receive study drug afterwards.

Patients will be treated with BAY73-4506 160 mg po qd for 3 weeks of every 4 week cycle (i.e., 3 weeks on, 1 week off). Patients will continue treatment with BAY73-4506 until disease progression, intolerable toxicity, or patient refusal to continue with the study or investigator decision to remove the patient from study.

Objective Tumor Response
Objective tumor response of a participant was defined as the best tumor response (confirmed Complete Response \[CR, tumor disappears\] or Partial Response \[PR, sum of lesion sizes decreased at least 30% from baseline\]) observed during trial period assessed according to the Response Evaluation Criteria in Solid Tumors (RECIST) committee.
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
Tumor Response
Tumor response of a participant was defined as the best tumor response (confirmed Complete Response \[CR, tumor disappears\], Partial Response \[PR, sum of lesion sizes decreased at least 30% from baseline\], Stable Disease \[SD, steady state of disease\], or Progressive Disease \[PD, sum of lesion sizes increased at least 20% from smallest sum on study or new lesions\]) observed during trial period assessed according to the RECIST committee.
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
Disease Control
Disease control was defined as the percentage of participants who had a best response rating of CR (tumor disappears), PR (sum of lesion sizes decreased at least 30% from baseline), or SD (steady state of disease) that was maintained for at least 28 days from the first demonstration of that rating.
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
Overall Survival
Overall survival (OS) was calculated as the time from the first date of receiving study medication to death, due to any cause. Participants alive at the time of analysis were censored at their last date of follow-up.

Time frame: From start of treatment of the first participant until database cut-off approximately 13 months later (13May2008 - 31May2009).
Progression-free Survival (PFS)
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
Time to Progression (TTP)
TTP was calculated as time from first date of receiving study drug until date of first documented disease progression (PD) (radiological or clinical, whichever was earlier). The actual date of tumor assessments (i.e., date on which radiological procedure was performed, rather than the scheduled date) was used for this calculation to determine both the event date and censoring date. Patients without PD 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
Duration of Response
Duration of response was defined as the time from the first documented objective response of PR or CR, whichever was earlier, to disease progression or death (if death occurred before progression was documented). Duration of response for subjects who had not progressed or died at the time of analysis were censored at the date of their last tumor assessment.
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
Duration of Stable Disease (SD)
Duration of SD was calculated as the time from the first date of receiving study drug until the date of documented PD or the last observation if the subject did not progress. Subjects without disease progression at the time of analysis were censored at the 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
