PD was defined as ≥20% relative increase and ≥5 mm of absolute increase in the SD of target lesions, taking as reference the smallest SD recorded since treatment started; or appearance of 1 or more new lesions. Time to response was defined as the time from first dose of study medication to the first assessment of CR or PR, which was the date the response was first documented by objective evidence, among participants with an overall response of CR or PR. | EPP Population; only participants with measurable disease at Baseline and a response of CR or PR were included. | Posted | | Median | Full Range | weeks | | Tumor assessments at Baseline; on Day 1 Cycles 3, 5, 7 (cycle length of 21 days); and at time of surgery following eight cycles of chemotherapy (approximately 6 months overall) | | | | ID | Title | Description |

| OG000 | Herceptin IV + Chemotherapy | Participants received eight cycles of Herceptin IV plus chemotherapy prior to surgery and ten cycles of Herceptin IV after surgery. Chemotherapy consisted of docetaxel 75 mg/m^2 every 21 days for four cycles followed by FEC every 21 days for four cycles.
