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.

This was a parallel group, three-arm, randomized, multicenter, open-label phase III study. The study compared the efficacy and tolerability of neoadjuvant lapatinib and paclitaxel, versus trastuzumab and paclitaxel, versus the combination of lapatinib with trastuzumab and paclitaxel given as neoadjuvant treatment in HER2/ErbB2 over-expressing and/or amplified primary breast cancer. Subjects were randomized to receive lapatinib, trastuzumab or lapatinib plus trastuzumab for a total of 6 weeks. After this biological window, subjects continued on the same targeted therapy plus weekly paclitaxel for a further 12 weeks, until definitive surgery (total neoadjuvant therapy duration of 18 weeks). Paclitaxel could be initiated at Week 4 if there is evidence of progressive disease (PD) at that time. Within 6 weeks after surgery, subjects received 3 cycles of adjuvant 5-flourouracil, epirubicin and cyclophosphamide (FEC) followed by the same targeted therapy as in the biological window of the neoadjuvant phase for a further 34 weeks (to complete 52 weeks of anti-HER2 therapy).

After completing 52 weeks of (neo-)/adjuvant anti-HER2 therapy, subjects were scheduled to attend post-treatment follow-up every 3 months during the first year (months 12, 15, 18, 21, and 24), every 6months in Years 3 to 5 inclusive, and annually thereafter up to Year 10. Each subject was to be followed for 10 Years. All subjects were to be followed for EFS and OS up to 10 years from last subject randomized.

Novartis is committed to sharing with qualified external researchers, access to patient-level data and supporting clinical documents from eligible studies. These requests are reviewed and approved by an independent review panel on the basis of scientific merit. All data provided is anonymized to respect the privacy of patients who have participated in the trial in line with applicable laws and regulations.

This trial data availability is according to the criteria and process described on www.clinicalstudydatarequest.com.

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.

The number of participants with overall response (complete response and/or partial response) was evaluated using World Health Organization (WHO) criteria by clinical examination and by mammography and breast echography with bi-dimensional measurements at Week 6. As per WHO criteria: complete response is defined as the disappearance of all lesions; partial response is defined as a greater than 50% decrease in the sum of products of the greatest length and width of the largest lesion; progressive disease is defined as a greater than 25% increase in the sum of products of all measurable lesions.

The number of participants with overall response (complete response and/or partial response) was evaluated using WHO criteria by clinical examination and mammography and breast echography with bi-dimensional measurements at the time of surgery (Weeks 20 to 22). As per WHO criteria: complete response is defined as the disappearance of all lesions; partial response is defined as a greater than 50% decrease in the sum of products of the greatest length and width of the largest lesion; progressive disease is defined as a greater than 25% increase in the sum of products of all measurable lesions.

Participants were assessed for node-negative lymph nodes at the time of surgery. As per the pathological TNM (Tumor, Node, Metastases) classification (pTNM) of malignant tumors: pN, absence or presence and extent of regional lymph node metastasis. Node-negative (pN0) participants had no regional lymph node metastasis. Although not assessed in this measure, pT is the extent of primary tumor, and pM is the absence or presence of distant metastasis.

Participants were assessed for the type of surgery they underwent for breast cancer. Non-conservative surgery is defined as a radical or modified radical mastectomy. Conservative surgery is comprised of a lumpectomy, a quadrantectomy/segmentectomy, or a partial mastectomy. Participants who were not assessed as being candidates for non-conservative or conservative surgery were classified as non-operable.

Mean change from baseline in tumor in tumor size. Change from baseline in tumor size was defined as tumor size at Week 6/ surgery (Weeks 20 to 22) minus tumor size at baseline. The difference in treatment arms was estimated for Lapatinib 1500 mg versus Trastuzumab 2 mg/kg and for Lapatinib 1000/750 mg + Trastuzumab 2 mg/kg versus Trastuzumab 2 mg/kg.

Participants with progressive disease at 4 week assessment that were permitted to commence treatment with paclitaxel.

Event free survival (EFS) is defined as the time from randomization to first EFS event. For subjects who had breast cancer surgery, EFS events were post-surgery breast cancer relapse, second primary malignancy or death without recurrence. For subjects who did not have breast cancer surgery, EFS events were death during clinical follow-up or non-completion of any neoadjuvant investigational product due to disease progression.

Overall survival is defined as the period from randomization until death (from any cause). OS was assessed annually for up to 10 years after the randomization of the last participant into the study.

The landmark date is 30 weeks after a subject's randomization. Subjects with missing pCR status were not included in the landmark analysis.

Clinical follow-up is the period during which the patient is monitored such that all recurrence or second primary malignancy (SPM) or contralateral breast cancer (CBC) events would be reported. Patients are considered in clinical follow-up from randomisation until one of the following occurs: lost to follow-up, withdrawal of consent, end of follow-up due to completion of year 10 visit, termination of study follow-up, or death.

The landmark date is 30 weeks after a subject's randomization. Subjects with missing pCR status were not included in the landmark analysis.

For patients who had breast cancer surgery, EFS events are post-surgery breast cancer relapse, second primary malignancy or death without recurrence. For patients who do not undergo breast cancer surgery, EFS events are death during clinical follow-up or non-completion of any neo-adjuvant investigational product due to disease progression or second primary malignancy or contralateral breast cancer.

The landmark date is 30 weeks after a subject's randomization. Subjects with missing pCR status were not included in the landmark analysis.

Patients are considered in survival follow-up from randomisation until one of the following occurs: lost to follow-up, withdrawal of consent, end of follow-up due to completion of year 10 visit, termination of study follow-up, or death. For subjects with no death recorded in the database, time to death is censored.

The landmark date is 30 weeks after a subject's randomization. Subjects with missing pCR status were not included in the landmark analysis. Includes deaths due to any cause.

Metabolic Response Rate determined by Positron Emission Tomography/Computed Tomography (PET/CT)

Biomarker levels of phosphatidylinositol 3-kinase (PI3K) catalytic subunit (PIK3CA) were assessed in participants at baseline.

Biomarker levels of phosphate and tensin homolog deleted from chromosome 10 (PTEN) were assessed in participants at baseline.

Ratio (95% CI) of geometric means in p95 human epidermal growth factor receptor (p95HER2) expression in hormone-receptor (HR) positive patients with pathological complete response (pCR) vs no pCR

Circulating tumor cells (CTCs) are cells that have detached from a primary tumor and circulate in the bloodstream. In the adjuvant phase, after surgery all participants received 3 courses of adjuvant 5-fluorouracil, epirubicin and cyclophosphamide, followed by lapatinib 1500 mg or trastuzumab 2 mg/kg or lapatinib 1000/750 mg plus trastuzumab 2 mg/kg given prior to surgery in the neoadjuvant setting for an additional 34 weeks.

Not applicable

Equivocal: Score of 2+

Positive: Score of 3+

Negative: Score of 0-1+

Non interpretable

An Immunohistochemistry (IHC) test gives a score of 0 to 3+, which indicates the amount of Human Epidermal Growth Factor (HER2) receptor proteins on the cancer cells in the sample tissue. A positive score (3+) indicates that HER2 receptor protein is present, a negative score (0-1+) indicates that no HER2 receptor protein is present, and an equivocal score (2+) indicates uncertainty and a result that is open for interpretation. Equivocal results require additional testing. "Not applicable" refers to the number of participants who did not have IHC testing done.

Amplified

Not amplified

Not interpretable

The Fluorescent In Situ Hybridization (FISH) assay was used to determine the overexpression and/or amplification of HER2 in the invasive component of the primary tumor. Amplified indicates that the cell is overexpressing copies of the HER2 gene. Not amplified indicates that there is no overexpression of copies of the HER2 gene. "Not applicable" refers to the number of participants who did not have the FISH assay performed.
