This single-arm open-label study will assess the safety, feasibility and efficacy of trastuzumab emtansine (T-DM1) after the completion of anthracycline-based adjuvant/neoadjuvant chemotherapy in patients with early HER2-positive breast cancer. Patients will receive T-DM1 3.6 mg/kg intravenously on Day 1 of each 3-week cycle, for up to 17 cycles.

Primary Outcome Measures:
  • Rate of cardiac events, defined as death from cardiac cause or severe congestive heart failure (NYHAC Class III or IV) with a decrease in LVEF of >/=10 absolute % points from baseline to an LVEF of <50% [ Time Frame: up to 51 weeks (17 cycles) of treatment + 6 months follow-up ] [ Designated as safety issue: Yes ]
  • Safety of T-DM1 as measured by the incidence, nature and severity of adverse events [ Time Frame: Up to 51 weeks (17 cycles) of treatment + 6 months follow-up ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Pathological complete response (pCR) rate in patients treated with neoadjuvant therapy [ Time Frame: Up to 51 weeks (17 cycles) ] [ Designated as safety issue: No ]
  • Safety of T-DM1 with concurrent radiotherapy and in patients who receive concurrent hormonal therapy will be measured by the incidence, nature, and severity of Adverse Events [ Time Frame: Up to 51 weeks (17 cycles) ] [ Designated as safety issue: No ]
  • Feasibility and tolerability of the planned duration of T-DM1 with concurrent radiotherapy [ Time Frame: Up to 51 weeks (17 cycles) ] [ Designated as safety issue: No ]
  • Feasibility and tolerability of the planned duration (up to 17 cycles) of T-DM1 [ Time Frame: Up to 51 weeks (17 cycles) ] [ Designated as safety issue: No ]
  • Disease-free survival (DFS) rate in patients treated with neoadjuvant therapy [ Time Frame: 12 months ] [ Designated as safety issue: No ]
  • DFS rate in patients treated with adjuvant therapy [ Time Frame: 12 months ] [ Designated as safety issue: No ]

Enrollment: 153

Arms Assigned Interventions
Experimental: A Drug: trastuzumab emtansine
3.6 mg/kg iv on Day 1 of each 3-week cycle, up to 17 cycles


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Adult patients, >/= 18 years of age
  • Locally advanced, inflammatory, or early stage, unilateral, and histologically confirmed invasive breast cancer documented at a local laboratory (Patients with inflammatory breast cancer must be able to have a core needle biopsy)
  • HER2-positive tumor, confirmed by central testing using IHC and ISH methods
  • Willingness to receive anthracycline-based chemotherapy or have received doxorubicin/cyclophosphamide (AC) OR 5-FU/epirubicin/cyclophosphamide (FEC) in a similar dose and schedule as described in the protocol as part of neoadjuvant or adjuvant treatment
  • For women of childbearing potential and men with partners of childbearing potential, agreement to use a highly effective, non-hormonal form of contraception or two effective forms of non-hormonal contraception by the patient and/or partner. Contraception use must continue for the duration of study treatment and for at least 6 months after the last dose of study treatment. Male patients should use condoms for the duration of the study. Specific country requirements will be followed.
  • Negative results of serum pregnancy test for premenopausal women of reproductive capacity and for women < 12 months after menopause
  • Patients may enroll before or after AC/FEC chemotherapy has completed.
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
  • Adequate hematologic, biochemistry and cardiac assessments

Exclusion Criteria:

  • Stage IV breast cancer or bilateral breast cancer
  • Pregnant or breastfeeding women
  • History of other malignancy within the previous 5 years, except contralateral breast cancer and ductal carcinoma in situ (DCIS)/lobular carcinoma in situ (LCIS), appropriately treated carcinoma in situ of the cervix, non-melanoma skin carcinoma, Stage I uterine cancer, or other cancers with outcome similar to those mentioned above
  • Radiation therapy, immunotherapy, or biotherapy within 5 years before study enrollment; non-cardiotoxic chemotherapy for malignancy treated > 5 years before study enrollment is allowed. Patients receiving AC/FEC in a similar fashion to the study treatment prescribed for adjuvant or neoadjuvant treatment of breast cancer will be allowed to enroll in the study after the completion of their AC/FEC. No other prior history of cardiotoxic chemotherapy is allowed.
  • Active cardiac history
  • Current chronic daily treatment with oral corticosteroids or equivalent
  • Patients with severe dyspnea at rest or requiring supplementary oxygen therapy
  • Active, unresolved infections at screening
  • HIV, HBV or HCV infection
  • Major surgery within 4 weeks before enrollment that is unrelated to the breast cancer
  • Patients for whom concomitant radiotherapy + T-DM1 may be contraindicated yet radiation therapy is planned
  • Known hypersensitivity to any of the study drugs or derivatives, including murine proteins
  • Grade >/= 2 peripheral neuropathy at baseline
