Primary Outcome Measures:
  • Progression free survival rate at 24 weeks [ Time Frame: 24 weeks after initiating study treatment ]

Secondary Outcome Measures:
  • Assess the objective response rate and duration of response in subjects with measurable disease [ Time Frame: 24 weeks ]
  • Safety through adverse event reporting and laboratory abnormalities [ Time Frame: 24 weeks and ongoing during the study until discontinuation of study medication (through last patient last visit) ]
  • Treatment failure rate [ Time Frame: 24 weeks ]
  • Anti-proliferative effects using FLT-PET ([18F]-3'-deoxy-3'-fluorothymidine positron emitting tomography) [ Time Frame: 14 days after initiating study treatment ]
  • Describe changes in various biomarkers related to breast cancer [ Time Frame: Ongoing during the study until discontinuation of study medication (about every 30 days until last patient last visit) ]
