Recruitment & Eligibility

• Status: ot Recruiting
• Sex: Not specified
• Target Recruitment: 2577

Inclusion Criteria

1. Signed written informed consent approved by the reviewing
independent Ethics Committee
2. Female or male aged 18 years or above
3. Eastern Cooperative Oncology Group (ECOG) performance status 0 or
1
4. Histologically confirmed early invasive HER2-positive carcinoma of the
breast with no evidence of residual, locally recurrent or metastatic
disease and defined as clinical stage I (T1, N0, M0) to IIIC (any T, N3,
M0) that is eligible for treatment with trastuzumab.
Note: Patients treated without neoadjuvant or adjuvant chemotherapy,
such as patients with low risk node negative tumours = 1.0 cm, elderly
patients (>65 years of age) or patients with HER2-positive EBC but
denying chemotherapy, will also be eligible to participate in the study,
but their enrolment will be limited to approximately 10% of the total
study population.
5. HER2-positive EBC, defined as IHC 3+, or a positive in situ
hybridization (ISH testing) by validate and approved methods within a
certified laboratory.
6. Screening left ventricular ejection fraction (LVEF) = 55% as measured
by echocardiography, Multi Gated Acquisition (MUGA) scan or Magnetic
Resonance Imaging (MRI) per local practice.
7. Agreement to use an adequate, non-hormonal means of contraception
by women of childbearing potential (defined as pre-menopausal and not
surgically sterilized or < 1 year after the onset of menopause) and by
male participants with partners of childbearing potential only. Examples
of adequate contraceptive measures are an intra-uterine device, a
barrier method (condoms, diaphragm) in conjunction with spermicidal
jelly, or total abstinence. Oral, injectable, or implant hormonal
contraceptives are not acceptable for females participating in the study.
8. Intact skin at site of SC injection on the thigh.

F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range 2200
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range 300

Exclusion Criteria

Cancer Related Criteria
1. Previous neoadjuvant or adjuvant breast cancer treatment with an
approved or investigational anti-HER2 agent
2. History of other malignancy which could affect compliance with the
protocol or interpretation of results (including previous invasive
ipsilateral or contralateral breast cancer). Patients with curatively
treated carcinoma in situ of the cervix or basal cell carcinoma, and
patients with other curatively-treated malignancies, other than breast
cancer, who have been disease-free for at least 5 years, are eligible.
3. Past history of ductal carcinoma in situ (DCIS) within the last 5 years
that has been treated with any systemic therapy OR with radiation
therapy to the ipsilateral breast where invasive cancer subsequently
develops. Patients who had their DCIS treated with surgery only are
allowed to enter the study.
4. Metastatic disease
Haematological, Biochemical and Organ Function Related Criteria
5. Inadequate bone marrow function (as indicated by any of the
following):
• Total white blood cell count < 2,500 / mm3 (<2.5 x 10e9/L)
• Neutrophil count < 1,500 / mm3 (< 1.5 x 10e9/L)
• Platelets < 100,000 / mm3 (< 100 x 10e9/L)
• Haemoglobin < 10 g/dL
6. Impaired hepatic function (as indicated by any of the following):
• Serum total bilirubin > 1.5 x upper limit of normal (ULN)
• Alanine amino transferase > 2.5 x ULN
• Aspartate amino transferase > 2.5 x ULN
• Alkaline phosphatase > 2.5 x ULN
7. Impaired renal function: serum creatinine > 1.5 x ULN
Other Study Drug Related Exclusion Criteria
8. Serious cardiac illness or medical conditions including but not
confined to:
• History of documented heart failure or systolic dysfunction (LVEF <
50%)
• High-risk uncontrolled arrhythmias such as atrial tachycardia with a
heart rate > 100/min at rest, significant ventricular arrhythmia
(ventricular tachycardia) or higher-grade atrioventricular (AV) block
(second degree AV-block Type 2 [Mobitz 2] or third degree AV-block)• Angina pectoris requiring anti-anginal medication
• Clinically significant valvular heart disease
• Evidence of transmural infarction on electrocardiogram (ECG)
• Poorly controlled or uncontrolled hypertension (blood pressure
consistently over 140/90 mmHg, despite treatment), or history of
hypertensive crisis or hypertensive encephalopathy
9. Other concurrent serious diseases that may interfere with planned
treatment including severe pulmonary conditions/illness
10. Prior maximum cumulative dose of doxorubicin >360 mg/m2 or
maximum cumulative dose of epirubicin >720 mg/m2 or equivalent
11. Known hypersensitivity to trastuzumab, murine proteins, or a
general hypersensitivity to adhesives (Cohort B
