to compare Disease Free Survival (DFS) of women with early-stage erbB-2 overexpressed/amplified breast cancer following trastuzumab in the adjuvant setting, receiving neratinib against that of women receiving placebo.

to compare the following endpoints of subjects receiving neratinib against those of subjects receiving placebo:
- Disease Free Survival including Ductal Carcinoma In Situ (DFS-DCIS), defined as the time from randomization to the first occurrence of any DFS event or DCIS.
- Time to Distant Recurrence (TTDR), defined as the time between randomization and the date of the first distant recurrence, or death from breast cancer.
- Distant Disease Free Survival (DDFS), defined as the time from randomization to the first occurence of distant recurrence or death from any cause.
- Incidence of central nervous system (CNS) recurrence, defined as the cumulative incidence of CNS recurrence at a site of first recurrence.
- Overall Survival (OS), defined as the time from randomization until the date of death.
- Short- and long-term safety (including incidence of grade 3/4 diarrhea). |

E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
A pharmacogenetic sub-study is conducted under this protocol. Upon separate consent, the original tumor biopsy sample will also be studied for: EGFR, erbB-2, erbB-3, and erbB-4 amplification, PIK3CA mutations in hotspots (ie, exons 9,20 via gene sequencing), PIK3CA amplification (q-PCR or FISH), PTEN loss, c-Myc amplification (q-PCR or FISH). Other assays will be explored. When disease recurrence is documented pathologically, specimens will be requested for biomarker analyses. |

2. Subjects must have histologically confirmed primary adenocarcinoma of the breast that is erbB-2 positive by one of the following assays, performed locally: Fluorescence in Situ Hybridization (FISH) or Silver in Situ Hybridization (SISH), or Chromogenic in Situ Hybridization (CISH), or Immunohistochemistry assay
3. Subjects with primary tumor ER/PgR status known before study entry.
4. Subjects must have completed a course of prior adjuvant trastuzumab. If less than 12 months of trastuzumab have been given, at least 8 prior doses of weekly trastuzumab, or at least 3 prior doses of trastuzumab given every 3 weeks must have been administered and it must be specified that the subject is either not eligible or unable to receive further adjuvant trastuzumab. The last dose of trastuzumab must have been given >2 weeks and <2 years from randomization.

Subjects must have a diagnosis of stage 1 through stage 3c primary breast cancer according to the American Joint Committee on Cancer (sixth edition) staging criteria for breast cancer and meet one of the following criteria: - Axillary node-positive disease OR node-negative disease with a tumor greater than or equal to 1.0 cm in greatest diameter. - Node-negative disease is defined as negative sentinel node biopsy OR no positive lymph nodes found among 6 ancillary nodes examined on axillary node dissection OR status after axillary radiotherapy for sterilization if clinically evaluated as cN0.
6. Subjects with adequately treated primary breast cancer with surgery, as defined by prior mastectomy OR lumpectomy, with margins clear of invasive carcinoma and ductal carcinoma in situ. Subjects with positive sentinel node biopsies must have subsequent axillary dissection to be eligible; negative sentinel node biopsies require no more axillary surgery for eligibility.
7. Subjects must have completed treatment with a neoadjuvant or adjuvant chemotherapy regimen containing either an anthracycline or a taxane or any cyclophosphamide, methotrexate and 5 fluorouracil (CMF) regimen.
8. Subjects with clinical and radiologic assessments that are negative for local or regional recurrence of disease or metastatic disease at the time of study entry, including - Bone scan; required only if alkaline phosphatase (ALP) is major or equal 2 x upper limit of normal (ULN) and/or there are symptoms of metastatic bone disease. A confirmatory imaging study is required if the results from the bone scan are questionable. - Computed tomography or ultrasound of the abdomen; required only if aspartate transaminase (AST)/alanine transaminase (ALT) or ALP is major or equal 2 x ULN, unless the elevation is in the bone fraction. - Chest radiograph.
9.Subjects with negative bilateral mammogram (or unilateral mammogram of the remaining breast if unilateral total mastectomy was performed) within 12 months before study entry. Mammogram is not indicated in case of bilateral total mastectomy.
10.Subjects with bilateral breast cancers are eligible only if their cancers are synchronous (ie, diagnosed at the same time [within 6 months of each other]). One or both tumors need to be erbB-2 positive. One could be negative.
11.Subjects must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1.

Subjects must have adequate organ function as defined by: - Absolute neutrophil count: major or equal 1.5 × 109/L (1500/mm3). - Platelet count: major or equal 100 × 109/L (100,000/mm3). - Hemoglobin: major or equal 9.0 g/dL (90 g/L). - Serum creatinine: minor or equal 1.5 x ULN. -Total bilirubin: minor or equal 1.5 × ULN (in case of known Gilbert´s syndrome, <2 x ULN is allowed). - AST and ALT: minor or equal 2.5 × ULN. - ALP: minor or equal 2.5 x ULN.
13. Subjects with Left ventricular ejection fraction (LVEF) within institutional range of normal; performed by multigated acquisition (MUGA) or echocardiogram (ECHO).
14. Negative beta-HCG pregnancy test (serum) for premenopausal women of reproductive capacity and for women less than 12 months after the menopause.

6. Subjects who have received any investigational agent within 14 days or 5 half-lives, whichever is longer, before administration of the first dose of investigational product.
7. Pregnant or breastfeeding women.
8. Subjects with a concurrently active second malignancy, other than adequately treated nonmelanoma skin cancers, in situ melanoma or in situ cervical cancer. Subjects with other nonmammary malignancies must have been disease free for at least 5 years.

14. Subjects with history of idiopathic ventricular tachycardia or ventricular fibrillation.
15. Subjects with a psychiatric illness that would prevent them from understanding the nature of the investigational therapy and complying with protocol requirements.
16. Subjects with any major concurrent illness or medical condition that, in the investigator´s judgment, will substantially increase the risk associated with the subject´s participation in and completion of the study.
