Summary:

      A Phase II study to investigate the potential utility of PD 0332991 in the treatment of early
      stage ER+ Human epidermal growth factor receptor 2 (HER2)- breast cancer, to investigate
      whether the combination of PD 0332991 and anastrozole is able to: 1) improve the pathologic
      complete response rate when compared to the historical control of single agent aromatase
      inhibitors, 2) result in fewer patients with on therapy Ki67>10% compared to historical
      control.
