Eligibility Criteria:
Inclusion Criteria:~* HER2-positive disease determined locally~* Histologically or cytologically confirmed invasive breast cancer~* Prior treatment for breast cancer in the adjuvant, unresectable, locally advanced or metastatic setting must include both chemotherapy, alone or in combination with another agent, and an anti-HER2 agent, alone or in combination with another agent~* Documented progression of incurable, unresectable, LABC, or mBC, defined by the investigator: progression must occur during or after most recent treatment for LABC/mBC or within 6 months of completing adjuvant therapy~* Measurable and/or non-measurable disease~* Left ventricular ejection fraction (LVEF) \>/=50% by either echocardiogram (ECHO) or multiple-gated acquisition scan (MUGA)~* Eastern Cooperative Oncology Group (ECOG) performance status of 0,1 or 2~* Adequate organ function~* Use of highly effective contraception as defined by the protocol~Exclusion Criteria:~* History of treatment with trastuzumab emtansine~* Prior enrollment into a clinical study containing trastuzumab emtansine regardless of having received trastuzumab emtansine or not~* Peripheral neuropathy of Grade \>/= 3 per National Cancer Institute (NCI) common terminology criteria for adverse events (CTCAE) v 4.0~* History of other malignancy within the previous 5 years, except for appropriately treated carcinoma in situ of the cervix, non-melanoma skin carcinoma, Stage 1 uterine cancer, synchronous or previously diagnosed HER2-positive breast cancer~* History of receiving any anti-cancer drug/biologic or investigational treatment within 21 days prior to first study treatment except hormone therapy, which can be given up to 7 days prior to first study treatment; recovery of treatment-related toxicity consistent with other eligibility criteria~* History of exposure to cumulative doses of anthracyclines~* History of radiation therapy within 14 days of first study treatment.

Study Arms:
- Trastuzumab Emtansine (All Participants) (Type: EXPERIMENTAL): This cohort will enroll all participants with HER2-positive, unresectable, LABC or mBC who have received prior anti-HER2 and chemotherapy treatment and have progressed on or after the most recent treatment for LABC or mBC, or within 6 months of completing adjuvant therapy. Participants will receive trastuzumab emtansine every 3 weeks until unacceptable toxicity, withdrawal of consent, or disease progression.
- Trastuzumab Emtansine (Asian Participants) (Type: EXPERIMENTAL): This cohort will enroll Asian race participants with HER2-positive, unresectable, LABC or mBC who have received prior anti-HER2 and chemotherapy treatment and have progressed on or after the most recent treatment for LABC or mBC, or within 6 months of completing adjuvant therapy. Participants will receive trastuzumab emtansine every 3 weeks until unacceptable toxicity, withdrawal of consent, or disease progression.

Based on this trial design, predict the completion outcome and termination type (if applicable).
