Brief Summary:

This research study is studying a combination of drugs as a possible treatment for breast cancer that has tested positive for a protein called HER2.

The names of the study interventions involved in this study are:

  • Trastuzumab emtansine (also called T-DM1)
  • Pertuzumab

Condition or disease Intervention/treatment Phase
HER-2 Positive Breast Cancer Breast Cancer Stage II Breast Cancer Stage III Breast Cancer Drug: T-DM1 Drug: Pertuzumab Procedure: Excision of tumor/mastectomy Phase 2

Detailed Description:
This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of an investigational intervention to learn whether the intervention works in treating a specific disease. "Investigational" means that the intervention is being studied. The FDA (the U.S. Food and Drug Administration) has not approved T-DM1 for pre-operative use in breast cancer but it has been approved for other uses in breast cancer. The FDA has approved pertuzumab as a pre-operative treatment.

Primary Outcome Measures :
  1. Rate of Pathologic Complete Response (pCR) by HER2 Amplification Status Non-Heterogeneous [ Time Frame: Evaluate upon completion of breast surgery, up to approximately 24 weeks from study enrollment. ]

    The rate of pCR is the percentage of participants with Residual Cancer Burden (RCB)=0 as defined by established guidelines (Symmans et al. JCO 2007; M.D Anderson http://www.mdanderson.org/breastcancer_RCB).

    Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.



Secondary Outcome Measures :
  1. Rate of Pathologic Complete Response (pCR) [ Time Frame: Evaluate upon completion of breast surgery, up to approximately 24 weeks from study enrollment. ]
    The rate of pCR is the percentage of participants with Residual Cancer Burden (RCB)=0 as defined by established guidelines (Symmans et al. JCO 2007; M.D Anderson http://www.mdanderson.org/breastcancer_RCB).

  2. Hormone Receptor (HR) Status by HER2 Amplification Status [ Time Frame: Day 0 (baseline/at study entry) ]
    HR status classified by estrogen receptor (ER) and/or progesterone receptor (ER) positive versus ER negative and PR negative determined by immunohistochemical methods according to the local institution's standard protocol.

  3. Median Disease-Free Survival [ Time Frame: Post-surgery follow-up of disease and survival occurs every 6 months for 5 years and annually until year 10. ]
    Disease-free survival (DFS) based on the Kaplan-Meier method is defined as the duration of time from study entry to the occurrence of the first of the following events: local/regional recurrence, contralateral invasive breast cancer, distant recurrence or death from any cause. In situ cancer is not included as DFS event. Participants alive without an event are censored at date of last disease assessment.

  4. Median Overall Survival [ Time Frame: Post-surgery follow-up of disease and survival occurs every 6 months for 5 years and annually until year 10. ]
    Overall survival (OS) based on Kaplan-Meier methods is defined as the interval from the date of registration to death from any cause. Patients are censored at date last known alive.

  5. Clinical Response Rate (Complete Response) [ Time Frame: Evaluate upon completion of neoadjuvant therapy, up to approximately 18 weeks from study enrollment. ]
    Clinical response rate was defined as the percentage of participants achieving complete response (CR) based on RECIST 1.1 criteria on treatment up to surgery. Per RECIST 1.1 for target lesions: CR is complete disappearance of all target lesions

  6. Clinical Response Rate (Partial Response) [ Time Frame: Evaluate upon completion of neoadjuvant therapy, up to approximately 18 weeks from study enrollment. ]
    Clinical response rate was defined as the percentage of participants achieving partial response (PR) based on RECIST 1.1 criteria on treatment up to surgery. Per RECIST 1.1 for target lesions: PR is at least a 30% decrease in the sum of longest diameter (LD) of target lesions, taking as reference baseline sum LD.

  7. Number of Participants With a Dose Reduction [ Time Frame: Evaluate upon completion of neoadjuvant therapy, up to approximately 18 weeks from study enrollment. ]
    Number of participants with ever having dose reduction on neoadjuvant therapy up to surgery.

  8. Treatment-Emergent Fatigue Rate [ Time Frame: Adverse events are assessed every cycle of neoadjuvant therapy prior to surgery, up to approximately 18 weeks (6 cycles) from study enrollment. ]
    Treatment-emergent fatigue rate is the percentage of participants who experienced grade 1-2 fatigue based on the Common Toxicity Criteria for Adverse Events (CTCAE) version 4.0 as reported on the adverse event case report form. CTCAE severity scale ranges from 0 (none) to 5 (death): Grade 1=mild and Grade 2=moderate.

  • Patients must have HER2-positive Stage II or III histologically confirmed invasive carcinoma of the breast. A minimum tumor size of 2 cm determined by physical exam or imaging is required.
  • HER-2 positive, confirmed by central testing (Clarient labs): IHC 3+ and/or FISH positive based on one of the three following criteria:
  • Single-probe average HER2 copy number≥6.0 signals/cell OR
  • Dual-probe HER2/CEP17 <2.0 with an average HER2 copy number ≥6.0 signals/cell OR
  • Dual-probe HER2/CEP17 ratio ≥2.0
  • ER/PR determination is required.
  • Bilateral breast cancers are allowed if both cancers are HER2-positive.

For subjects with a clinically negative axilla, a sentinel lymph node biopsy will be performed either before or after preoperative therapy at the discretion of the subject's physicians. For subjects with a clinically positive axilla, a needle aspiration, core biopsy or SLN procedure will be performed to determine the presence of metastatic disease in the lymph nodes.
