Study Summary

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.

Primary Outcome

ORR was defined as the percentage of participants who achieved complete response (CR, complete disappearance of all target lesions with the exception of nodal disease; all target nodes must have decreased to normal size \[short axis \<10 mm\]) or partial response (PR, \>=30% decrease from baseline of the sum of diameters (SOD) of all target measurable lesions; the short diameter was used in the sum for target nodes, while the longest diameter was used in the sum for all other target lesions) by
