Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
A total of 107, 107, 107, and 96 participants (total 417) were randomized to Arms Trastuzumab plus (+) Docetaxel (T+ D) , Trastuzumab+Pertuzumab+Docetaxel (T+Ptz+D), Trastuzumab+Pertuzumab (T+Ptz), and Pertuzumab+Docetaxel (Ptz+D), respectively and were included in intent-to-treat population (as randomized).

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
3 participants did not receive correct treatment, as randomized, and 1 (in Arm Trastuzumab + Docetaxel) did not receive any treatment. Safety population (as treated) included 107, 107, 108, and 94 participants in Arms ‘T+D’, ‘T+Ptz+D’, ‘T+Ptz’, and ‘Ptz+D’, respectively. Participant flow was available for “As Treated” participants.
