Primary Outcome Measures:
  • To evaluate the use of PET as an assessment of target modulation. [ Time Frame: 1 year ] [ Designated as safety issue: No ]
  • To assess the overall safety profile characterized by type, incidence, severity, timing, seriousness, and relationship to study therapy of adverse events and any laboratory abnormalities. [ Time Frame: 2 years ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Explore potential PD-0332991 concentration-effect relationships. [ Time Frame: 2 years ] [ Designated as safety issue: No ]
  • Evaluate efficacy with diseases assessments: Progression Free Survival (PFS), Overall Response Rate (ORR), Duration of Response (DR), and time to Tumor Progression (TTP) [ Time Frame: 2 years ] [ Designated as safety issue: No ]
