The current study will compare the efficacy, safety, pharmacokinetics and immunogenicity of PF-05280014 in combination with paclitaxel versus trastuzumab sourced from the European Union (trastuzumab-EU) with paclitaxel in female patients with HER2-positive, metastatic breast cancer in the first-line treatment setting. The hypothesis to be tested in this study is that the efficacy (ORR) of PF-05280014 is similar to trastuzumab-EU.
Concentrate for solution for infusion, sterile vial 150 mg. Initial dose of 4 mg/kg over 90 minutes (depending on tolerability) IV infusion, then 2 mg/kg over 30 to 90 minutes (depending on tolerability) IV infusion until disease progression. Following completion of the paclitaxel administration period and beginning no earlier than Week 33 of the study, the PF-05280014 regimen may be changed at the discretion of the investigator to every 3 weeks at a dose of 6 mg/kg infused over 30 to 90 minutes depending on tolerability.
A nonaqueous solution intended for dilution with a suitable parenteral fluid prior to intravenous infusion. Paclitaxel is available in 30 mg (5 mL), 100 mg (16.7 mL), and 300 mg (50 mL) multidose vials. Each mL of sterile nonpyrogenic solution contains 6 mg paclitaxel. The starting dose of paclitaxel will be 80 mg/m\^2 by IV infusion over 60 minutes (duration of infusion may be modified according to local standard of care, if applicable). Provision is made for dose reduction to 70 mg/m\^2 and then 60 mg/m\^2 as needed. In the absence of disease progression in the judgment of the investigator or prohibitive toxicity, patients will receive treatment with paclitaxel for at least 6 cycles or until maximal benefit of response is obtained, in the judgment of the investigator.

Initial dose of 4 mg/kg over 90 minutes (depending on tolerability) IV infusion, then 2 mg/kg over 30 to 90 minutes (depending on tolerability) IV infusion weekly until disease progression. Following completion of the paclitaxel administration period and beginning no earlier than Week 33 of the study, the Herceptin® regimen may be changed at the discretion of the investigator to every 3 weeks at a dose of 6 mg/kg infused over 30 to 90 minutes depending on tolerability.
