Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will determine the recommend dose of palbociclib in combination with letrozole and another medication, Ado-trastuzumab emtansine (T-DM1). Additionally, researchers will determine how well this recommended dose will improve outcomes in this type of advanced breast cancer.

The study will include a safety lead-in with escalating dosing of palbociclib to determine the recommended phase II dose (RP2D) of palbociclib in this combination and an expanded phase II of palbociclib at the RP2D in combination with letrozole and Ado- trastuzumab Emtansine (T-DM1).

The starting dose of palbociclib will be 75 milligrams (mg) by mouth (PO) daily for each 21 day cycle. If 0 of 3 patients at the 75mg dose level experience a dose limiting toxicity (DLT), the next 3 patients will be enrolled at the next higher dosing cohort of 100mg PO daily for each 21 day cycle. If 0 of 3 patients at the 100mg dose level experience a DLT, the next 3 patients will be enrolled at the next higher dosing cohort of 125mg PO daily for each 21 day cycle. If 0 of 3 patients at the 125mg dose level experience a DLT, 125mg PO daily of palbociclib will be the phase II recommended dose used in the phase II expanded cohort. Patients receiving the phase II recommended dose in phase I will be enrolled in phase II of the study.

During safety lead-in and expanded phase II, Letrozole 2.5mg PO will be administered daily for each 21 day cycle and T-DM1 3.6 milligrams per kilograms intravenously (IV) will be administered on Day 1 of each 21 day cycle.
