Brief Summary
This is a randomised, open label multicenter Phase III study comparing the efficacy of neoadjuvant lapatinib plus paclitaxel, versus trastuzumab plus paclitaxel, versus concomitant lapatinib and trastuzumab plus paclitaxel given as neoadjuvant treatment in HER2/ErbB2 over-expressing and/or amplified primary breast cancer. Patients will be randomised to receive either: lapatinib 1500 mg daily, trastuzumab 4 mg/kg intravenous (IV) load followed by 2 mg/kg IV weekly, or lapatinib 1000 mg daily with trastuzumab 4 mg/kg IV load followed by 2 mg/kg IV weekly for a total of 6 weeks. After this biological window, patients on monotherapy arms will continue on the same targeted therapy plus weekly paclitaxel 80 mg/m\^2 for a further 12 weeks, up to definitive surgery. In the combination arm, patients will receive lapatinib 750 mg daily in combination with trastuzumab 2 mg/kg IV plus weekly paclitaxel 80mg/m\^2 IV for a further 12 weeks, up to definitive surgery. After surgery, patients will receive three courses of adjuvant chemotherapy with 5-Fluorouracil Epirubicin Cyclophosphamide (FEC) followed by the same targeted therapy as in the biological window of the neoadjuvant setting for a further 34 weeks (in the combination arm, lapatinib dose will be 1000 mg daily in combination with trastuzumab). The planned total duration of the anti-HER2 therapy one year. Primary objective is to evaluate and compare the rate of pathological complete response (pCR) at the time of surgery in patients with HER2/ErbB2 overexpressing or amplified operable breast cancer randomised to lapatinib followed by lapatinib plus paclitaxel versus trastuzumab followed by trastuzumab plus paclitaxel versus lapatinib in combination with trastuzumab followed by lapatinib, trastuzumab plus paclitaxel.

Outcome Measures
Primary Outcomes (1)
Number of Participants With Pathological Complete Response (pCR) at the Time of Surgery
Pathological complete response is defined as no invasive cancer in the breast or only non-invasive in situ cancer in the breast specimen. Surgical breast and axillary node resection specimens were evaluated for pathologic tumor response according to National Surgical Adjuvant Breast and Bowel Project (NSABP) guidelines, which do not take into account the histological nodal status.

Study Arms (3)
Arm 1 Lapatinib
EXPERIMENTAL1500 mg lapatinib for 6 weeks followed by lapatinib plus weekly paclitaxel for an additional 12 weeks. After definitive surgery, 3 cycles of adjuvant FEC followed by 34 weeks of adjuvant lapatinib.
Arm 2 Trastuzumab
ACTIVE COMPARATOR4 mg/kg IV loading dose followed by 2 mg/kg IV weekly trastuzumab for 6 weeks followed by 2 mg/kg trastuzumab plus weekly paclitaxel for an additional 12 weeks.

- Patients with a prior malignancy diagnosed more than 10 years prior to randomisation may enter the study. Patients must have been curatively treated with surgery alone. Radiation therapy or systemic therapy (chemotherapy or endocrine) are NOT permitted. Prior diagnoses of breast cancer or melanoma are excluded.
- Diagnosis of inflammatory breast cancer;
