To determine if adding palbociclib to standard treatment with anti-HER2-based therapy plus endocrine therapy is more effective in preventing cancer from getting worse.


  • Palbociclib (Ibrance)   
  • Lab Biomarker Analysis
  • Quality of Life questionnaires
  • ARM I:  Palbociclib + standard endocrine and anti-HER2-based therapy
  • ARM II: Standard endocrine and anti-HER2-based therapy alone
