The subjects will be administered T-DM1 by intravenous infusion at 3.6 mg/kg for 90 minutes on day 1 of each 21 day cycle. Infusion timing may vary from 30-90 minutes depending on how well the subject tolerates the treatment.

Cohort 1 : PD-0332991 - 100 mg daily (oral) Cohort 2 : PD-0332991 - 150 mg daily (oral) Cohort 3 : PD-0332991 - 200 mg daily (oral) The 3+3 design entails that if one patient out of the first three patients has a DLT, up to three additional patients will be entered at that dose level Treatment cycles will continue until disease progression or withdrawal from study.
