Primary Outcome Measures
NameTimeMethod
<br>Outcome name:Pre-dose samples were obtained prior to surgery (Cycle 8). The observed Ctrough was recorded, averaged among all participants, and expressed in micrograms per milliliter (&#956;g/mL).<br><br>Measure:Observed Serum Trough Concentration (Ctrough) of Trastuzumab Prior to Surgery<br>Timepoints:Pre-dose (0 hours) on Day 1 of Cycle 8 (cycle length of 21 days)<br>;<br>Outcome name:Participants were evaluated following eight cycles of treatment and after surgery to assess for pCR, defined as absence of neoplastic invasive cells in the breast according to pathologist examination. The percentage of participants with pCR was reported, and the 95% CI for one-sample binomial was constructed using the Pearson-Clopper method.<br><br>Measure:Percentage of Participants With Pathological Complete Response (pCR)<br>Timepoints:After surgery following eight cycles of Herceptin + chemotherapy (approximately 6 months from Baseline)<br>
