A Phase II Uncontrolled Study of BAY73-4506 in Previously Untreated Patients With Metastatic or Unresectable RCC

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).

Overall Participants Analyzed  [Units: Participants]	49
Age  [Units: Years] Median (Full Range)	62.0   (40 to 76)
Sex: Female, Male  [Units: Participants] Count of Participants
Female	22  44.9%
Male	27  55.1%
Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) [1]  [Units: Participants]
0	30
1	19
[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.
Overall Motzer Score [1]  [Units: Participants]
Low	24
Intermediate	25
[1] 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.
