1. Female aged 18-65 years
2. Eastern Cooperative Oncology Group (ECOG) performance status of 0-1
3. Non-metastatic, unilateral newly diagnosed primary breast cancer of clinical stage II to III including inflammatory breast cancer with:
a. tumour size = 2 cm
b. histologically confirmed primary invasive adenocarcinoma of the
breast
c. HER2-positivity confirmed by a central laboratory or an accredited local laboratory and defined as immunohistochemistry (IHC) 3+ or fluorescence in situ hybridisation (FISH) +:
4. Known hormone receptor (oestrogen receptor and progesterone receptor) status
5. Baseline LVEF = 55% measured by echocardiography or mmultiple gated acquisition (MUGA) scan
6. Subjects must be able to provide informed consent, which must be obtained prior to any study related procedures
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range 498
F.1.3 Elderly (>=65 years) no
F.1.3.1 Number of subjects for this age range
1. Metastatic (stage IV) or bilateral or clinically detectable two separate
breast cancer masses by physical examination (palpation).
2. History of any prior invasive breast carcinoma, except for subjects with a past history of ductal carcinoma in situ (DCIS) and/or lobular carcinoma in situ (LCIS) treated with surgery only.
3. Past or current history of malignant neoplasms within 5 years prior to Randomisation, except for curatively treated carcinoma in situ of uterine cervix, basal cell carcinoma of the skin or squamous cell carcinoma of the skin (malignant neoplasm occurring more than 5 years prior to Randomisation are permitted if curatively treated with surgery only)
4. Previous history of radiation therapy (RT), immunotherapy, chemotherapy or biotherapy (including prior HER2 directed therapy)
5. Major surgery within 4 weeks prior to Randomisation and minor
surgery within 2 weeks prior to Randomisation (major surgery is defined
as surgery which requires general anaesthesia); the diagnostic
procedures such as open and/or core-needle biopsies will not be
regarded as surgeries mentioned above; SLNB before initiation of
neoadjuvant therapy will be exempted from this criterion)
6. Serious cardiac illness that would preclude the use of trastuzumab such as:
a. history of documented CHF (NYHA class II or greater heart disease)
b. LVEF < 55% by echocardiography or MUGA scan
c. angina pectoris requiring anti-anginal medication
d. evidence of transmural infarction on Electrocardiogram (ECG)
e. uncontrolled hypertension (systolic > 180 mmHg and/or diastolic > 100 mmHg)
f. clinically significant valvular heart disease
g. high risk uncontrolled arrhythmias
7. Serious pulmonary illness enough to cause dyspnoea at rest or requiring supplementary oxygen therapy
8. Known history of HBV (excluding immunized or fully recovered from
the past infection), HCV or HIV infection
9. Other concurrent serious illnesses that may interfere with planned treatment including severe cardiovascular, pulmonary, metabolic or infectious conditions
10. Known hypersensitivity to the IPs, non-IPs or any ingredients or excipients of the IPs or non-IPs
11. Known hypersensitivity to murine proteins
12. Known history of dihydropyrimidine dehydrogenase (DPD) deficiency
13. Pre-existing peripheral sensory or motor neuropathy = grade 2, defined by NCI-CTCAE v4.0
14. Any of the following abnormal laboratory tests
a. serum total bilirubin > 1.5 × upper limit of normal (ULN); in cases of known Gilberts syndrome, level of total bilirubin within 3 × ULN is permitted
b. aspartate transaminase (AST) and/or alanine transaminase (ALT) > 1.5 × ULN
c. alkaline phosphatase (ALP) > 2.5 × ULN
d. serum creatinine > 1.5 × ULN
e. haemoglobin (Hb) < 9 g/dL
f. absolute neutrophil count (ANC) < 1500/mm3 (< 1.5 × 109/L)
g. platelets count < 100000/mm3 (< 100 × 109/L)
15. Pregnant or lactating women. A pregnancy test result is required for all women of childbearing potential including women who had menopause onset within 2 years prior to Randomisation. Women of childbearing potential must agree to use non-hormonal contraceptive methods (see section 7.4.2.) during the study and 7 months after the last dose IP
16. Concurrent hormonal therapy including birth control pills, ovarian hormone replacement for menopause, selective oestrogen receptor modulator (SERM) either for osteoporosis or breast cancer prevention
17. Subjects unwilling to follow the study requirements

- Secondary Outcome Measures
Name Time Method Secondary end point(s): • Total pathologic complete response, defined as the absence of invasive residual in both breast and lymph nodes<br>• Overall clinical response rate during neoadjuvant therapy (tumour size will be measured by ultrasound or caliper)<br>• Event-free survival (EFS), defined as the time from the date of randomisation to the date where an event occurs. An event is disease recurrence or progression (local, regional, distant or contralateral) or death due to any cause<br>• Overall survival (OS), defined as the time from the date of randomisation to the date of death, regardless of the cause of death. Subjects who were alive at the time of analysis will be censored at the date of the last follow up assessment;Timepoint(s) of evaluation of this end point: Measured at various intervals in the study from beginning to end as per Protocol.
