Description:
The current study will compare PK, efficacy, safety, and immunogenicity of PF-05280014
(Trastuzumab-Pfizer) in combination with Taxotere® and Carboplatin (Paraplatin) versus
Herceptin® (Trastuzumab-EU) approved in the EU in combination with Taxotere® and Carboplatin
(Paraplatin) in patients with operable HER2 positive, breast cancer in the neoadjuvant
setting. The hypothesis to be tested in this study is the percentage of patients with steady
state Cycle 5 Ctrough (Cycle 6 pre-dose) >20 µg/mL of trastuzumab-Pfizer is similar to
EU-approved trastuzumab, using a margin of -12.5%.

Eligibility Criteria
Inclusion Criteria:
- Histologically confirmed HER2 overexpressing invasive breast cancer.
- Plan for definitive surgical resection of breast tumor (i.e., lumpectomy or
mastectomy, and sentinel node (SN) biopsy or axillary lymph node dissection (ALND).
- Plan for neoadjuvant chemotherapy.
- Measurable disease in the breast after diagnostic biopsy, defined as longest diameter
≥ 2.0 cm.
Exclusion Criteria:
- Bilateral breast cancer.
- Inflammatory breast cancer.
- Presence of known distant metastases.
- Received prior treatment, including chemotherapy, endocrine therapy, biologic therapy,
radiation or surgery with the exception of diagnostic biopsy for primary breast
cancer.
Maximum Eligible Age: | N/A |
Minimum Eligible Age: | 18 Years |
Eligible Gender: | Female |
Healthy Volunteers: | No |
Primary Outcome Measures
Measure: | Percentage of Participants With Steady State Drug Concentration Ctrough (Cycle 6 Pre-dose) >20 µg/mL at Cycle 5. |
Time Frame: | Cycle 5 |
Safety Issue: | |
Description: | The percentage of participants with Cycle 5 Ctrough (Cycle 6 pre-dose) >20 μg/mL in each treatment group, the denominator being the number of participants in the per protocol population for each treatment group. |
Secondary Outcome Measures
Measure: | Mean Predose Trastuzumab-Pfizer and Trastuzumab-EU Concentrations at Cycles 1 Through 6. |
Time Frame: | Cycles 1 through 6 |
Safety Issue: | |
Description: | Samples of blood were taken pre-dose on Cycles 1, 2, 4, 5, and 6, and at 1 hour post dose on Cycles 1 and 5 for pharmacokinetic evaluation. |
Measure: | Pathologic Complete Response (pCR) Defined as the Absence of Invasive Neoplastic Cells in the Breast and Lymph Nodes. |
Time Frame: | Cycle 6/End of treatment |
Safety Issue: | |
Description: | Following surgery after treatment completion, tumors were assessed as Complete Pathological Response, Partial Pathological Response, or No Pathological Response. |
Measure: | Objective Response Rate (ORR) Defined as the Percentage of Participants Having Complete or Partial Response at End of Treatment, Based on Radiographic Assessments of the Tumor. |
Time Frame: | Cycle 6/End of treatment |
Safety Issue: | |
Description: | ORR was defined as Complete Response (CR), Partial Response (PR), Stable (SD), Progressive Disease (PD) or Indeterminate (IND). ORR was the percentage of participants who had CR or PR at Cycle 6/End of treatment. |
Measure: | Incidence of Anti-trastuzumab Antibodies (ADAs) at Cycles 1 Through 6. |
Time Frame: | Cycles 1 through 6 |
Safety Issue: | |
Description: | The number of participants with positive (titer >=1.00) pre-dose ADA samples, participants counted towards the total if for at least one sample, the ADA was positive. |
Measure: | Incidence of Neutralizing Antibodies (NAb) at Cycles 1 Through 6. |
Time Frame: | Cycles 1 through 6 |
Safety Issue: | |
Description: | The number of participants with positive (NAb response >=1.48) pre-dose NAb samples, participants counted towards the total if for at least one sample, the NAb was positive. |
