Primary Outcome Measures:
  • Changes in cardiac function [ Time Frame: Through study completion or early study discontinuation ]
  • Changes in vital signs, physical findings, and clinical laboratory results during and following administration of study drugs that result in dose modification, dose delay, or discontinuation of T-DM1 and/or GDC 0941 [ Time Frame: Through study completion or early study discontinuation ]
  • Incidence, nature, and severity of adverse events [ Time Frame: Through study completion or early study discontinuation ]

Secondary Outcome Measures:
  • PK parameters of T-DM1 and GDC-0941 (total exposure, maximum serum concentration, and minimum concentration) [ Time Frame: Through study completion or early study discontinuation ]

  • Objective response based on investigator assessment [ Time Frame: Confirmed response >/= 4 weeks after initial documentation of response ]
  • Duration of response [ Time Frame: Time from initial complete or partial response to the time of disease progression or death on study ]
