Brief Summary:
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%.

Arm Intervention/treatment
Experimental: PF-05280014 Biological: PF-05280014
Concentrate for solution for infusion, sterile vial 150 mg, Day 1 Cycle 1 will be a loading dose of 8 mg/kg infused over 90 minutes. Subsequent infusions will follow every 3 weeks (i.e., cycled every 21 days) with a dose of 6 mg/kg administered over 30 to 90 minutes depending on tolerability, maximum of 6 cycles.

Drug: Taxotere®
Injection concentrate single-dose vials containing 20 mg (0.5 mL) or 80 mg (2 mL), each mL contains 40 mg docetaxel (anhydrous) and 1040 mg polysorbate 80, The starting dose of Taxotere® (docetaxel) will be 75 mg/m2 administered intravenously over 60 minutes every three weeks on Day 1 of each cycle (i.e., every 21 days), maximum 6 cycles.
Other Name: docetaxel

Drug: Paraplatin®
Lyophilized powder, single-dose vials containing 50 mg, 150 mg, and 450 mg of Carboplatin for administration by intravenous infusion (each vial contains equal parts by weight of Carboplatin and mannitol), starting dose 6 AUC, over 15 minutes or longer every three weeks on Day 1 of each cycle (i.e., every 21 days), maximum 6 cycles.
Other Name: carboplatin
Active Comparator: Herceptin® Biological: Trastuzumab-EU
Concentrate for solution for infusion, sterile vial 150 mg, Day 1 Cycle 1 will be a loading dose of 8 mg/kg infused over 90 minutes. Subsequent infusions will follow every 3 weeks (i.e., cycled every 21 days) with a dose of 6 mg/kg administered over 30 to 90 minutes depending on tolerability, maximum 6 cycles.

Drug: Taxotere®
Injection concentrate single-dose vials containing 20 mg (0.5 mL) or 80 mg (2 mL), each mL contains 40 mg docetaxel (anhydrous) and 1040 mg polysorbate 80, The starting dose of Taxotere® (docetaxel) will be 75 mg/m2 administered intravenously over 60 minutes every three weeks on Day 1 of each cycle (i.e., every 21 days), maximum 6 cycles.
Other Name: docetaxel

Drug: Paraplatin®
Lyophilized powder, single-dose vials containing 50 mg, 150 mg, and 450 mg of Carboplatin for administration by intravenous infusion (each vial contains equal parts by weight of Carboplatin and mannitol), starting dose 6 AUC, over 15 minutes or longer every three weeks on Day 1 of each cycle (i.e., every 21 days), maximum 6 cycles.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Percentage of Participants With Steady State Drug Concentration Ctrough (Cycle 6 Pre-dose) >20 µg/mL at Cycle 5. [ Time Frame: Cycle 5 ]
    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 :
  1. Mean Predose Trastuzumab-Pfizer and Trastuzumab-EU Concentrations at Cycles 1 Through 6. [ Time Frame: Cycles 1 through 6 ]
    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.

  2. 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 ]
    Following surgery after treatment completion, tumors were assessed as Complete Pathological Response, Partial Pathological Response, or No Pathological Response.

  3. 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 ]
    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.

  4. Incidence of Anti-trastuzumab Antibodies (ADAs) at Cycles 1 Through 6. [ Time Frame: Cycles 1 through 6 ]
    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.

  5. Incidence of Neutralizing Antibodies (NAb) at Cycles 1 Through 6. [ Time Frame: Cycles 1 through 6 ]
    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.
