Primary Outcome Measures:
  • Time to Tumor Progression (TTP) as Assessed by Imaging Studies at End of Double-blind Treatment Phase [ Time Frame: Day 28 of each 6-week cycle : duration of double-blind treatment phase ]
  • Time to Tumor Progression (TTP) as Assessed in the Double-blind Treatment Phase at End of Study [ Time Frame: Day 28 of each 6-week cycle : duration of double-blind treatment phase after Last Subject Last Visit (LSLV) ]

Secondary Outcome Measures:
  • Progression Free Survival (PFS) [ Time Frame: Day 28 of each cycle : duration of double-blind treatment phase ]
  • Overall Survival Status of Subjects [ Time Frame: clinic visit or telephone contact every 2 months for up to 3 years from the last dose of study drug ]
  • Overall Survival [ Time Frame: clinic visit or telephone contact every 2 months for up to 3 years from the last dose of study drug ]
  • Overall Survival Based on the Rank Preserving Structural Failure Time Method [ Time Frame: clinic visit or telephone contact every 2 months for up to 3 years from the last dose of study drug ]
  • Best Overall Tumor Response During Double-blind Treatment Phase [ Time Frame: Day 28 of each cycle : duration of double-blind treatment phase ]
  • Confirmed Objective Response (CR or PR) in Subjects [ Time Frame: Day 28 of each cycle : duration of double-blind treatment phase ]
  • Time to Tumor Response (TTR) [ Time Frame: Day 28 of each cycle : duration of double-blind treatment phase ]
  • Duration of Performance Status Maintenance [ Time Frame: Day 28 of each cycle : duration of double-blind treatment phase ]
  • Time to Pain Progression Using McGill Pain Questionnaire-present Pain Intensity (MPQ-PPI) [ Time Frame: Day 1 & 28 of each cycle : duration of double-blind treatment phase ]
  • Subjects With Pain Relief Response Using McGill Pain Questionnaire-present Pain Intensity (MPQ-PPI) [ Time Frame: Day 1 & 28 of each cycle : duration of double-blind treatment phase ]
  • Change From Baseline Score in EuroQoL Visual Analog Scale (EQ-VAS) [ Time Frame: Day 1 & 28 of each cycle : duration of double-blind treatment phase ]
  • Change From Baseline in EQ-5D Health State Profile Index [ Time Frame: Day 1 & 28 of each cycle : duration of double-blind treatment phase ]
