Key inclusion & exclusion criteria
|
Inclusion Criteria:
- Age = 18 years
- Eastern Cooperative Oncology Group (ECOG) performance status = 1;
- Non-metastatic operable primary invasive adenocarcinoma of the breast fulfilling the
following:
1. Histologically confirmed
2. Adequately excised (exceptions: patients who have 'non-resectable' deep margin
invasion are eligible provided they have had or will receive radiotherapy
encompassing the region concerned; patients with histologically documented
infiltration of the skin (pT4) are eligible provided they have undergone or will
receive radiotherapy encompassing the tumour bed);
3. Axilla dissected; sentinel node sampling is allowed provided that axillary
dissection follows confirmation of a positive sentinel node; sentinel node
sampling alone is NOT acceptable after neoadjuvant chemotherapy (in patients
receiving neoadjuvant chemotherapy lymph node status will be considered unknown,
regardless of the results of post-chemotherapy axillary dissection);
4. Axillary node positive patient OR node negative patient with a tumour greater
than or equal to 1.0 cm in greatest diameter. For clarification, isolated tumour
cells (ITC) are considered pN0 and micrometastases are considered pN1
- Known hormone receptor status (ER/PgR or ER alone)
- For Designs 1 and 2: Patients must have received at least four cycles of an approved
anthracycline-based (neo-) adjuvant chemotherapy regimen or listed as an exception in
Table 5 of the protocol.
For Design 1: Randomization must be performed no longer than 12 weeks from day 1 of the
last chemotherapy cycle after obtaining a post-chemotherapy LVEF = 50. Study treatment must
start no more than 14 days after randomization For Design 2: Randomization must be
performed no longer than 6 weeks from day 1 of the last anthracycline-containing
chemotherapy cycle after obtaining a post-anthracycline chemotherapy LVEF = 50. Study
treatment must start no more than 14 days after randomization and must be concurrent with
taxanes.
For Design 2B: Randomisation must be performed no longer than 8 weeks from definitive
surgery. Non-anthracycline platinum containing regimen (docetaxel and carboplatin) and
study treatment must start concomitantly and no more than 14 days after randomisation.
- Baseline LVEF =50% measured by echocardiography or MUGA scan. For Design 1 and Design
2 - after completion of all anthracycline-based (neo-) adjuvant chemotherapy and prior
to the targeted therapy(ies); for Design 2B - prior to targeted therapy(ies) and
chemotherapy (docetaxel and carboplatin)
- Over expression and/or amplification of HER2 in the invasive component of the primary
tumour (in case of neoadjuvant treatment, tissue sample used for HER2 testing should
be collected before neoadjuvant treatment starts), according to one of the following
definitions [Wolff et al 2007] and confirmed by central laboratory prior to
randomization:
- 3+ over expression by IHC (> 30% of invasive tumour cells);
- 2+ or 3+ (in 30% or less neoplastic cells) over expression by IHC AND in situ
hybridization (FISH/CISH) test demonstrating HER2 gene amplification;
- HER2 gene amplification by FISH/CISH ( > 6 HER2 gene copies per nucleus, or a FISH
ratio [HER2 gene copies to chromosome 17 signals] of > than 2.2.) Patients with a
negative or equivocal overall result (FISH test ratio of = 2.2, = 6.0 HER2 gene copies
per nucleus) and staining scores of 0, 1+, 2+ or 3+ (in 30% or less neoplastic cells)
by IHC are not eligible for participation in the trial.
Equivocal local results may be submitted for a final determination by the central
laboratory.
- Completion of all necessary baseline laboratory and radiological investigations
- Signed written informed consent (approved by an Independent Ethics Committee (IEC) and
obtained prior to any study specific screening procedures).
Exclusion Criteria:
- History of any prior (ipsi- and/or contralateral) invasive breast carcinoma;
- Past (less than 10 years) or current history of malignant neoplasms, except for
curatively treated 1) basal and squamous cell carcinoma of the skin or 2) carcinoma in
situ of the cervix.
NOTE: Patients with a prior malignancy diagnosed greater than 10 years in the past who have
been curatively treated with surgery ONLY, WITHOUT radiation therapy or systemic therapy
(chemotherapy or endocrine) are eligible for the study. Patients with any prior diagnosis
of breast cancer or melanoma, at any time, are excluded from this study.
- Any clinically staged T4 tumour, including inflammatory breast cancer;
- Bilateral tumours;
- This exclusion criterion has been removed as of protocol amendment 1.
NOTE: multifocal/multicentric tumours are permitted:
- If the patient is node-negative: one of the lesions must be equal or greater than 1.0
cm (sum of the lesion diameters is not acceptable) AND must have positive HER2 status
centrally-confirmed;
- If patient is node-positive: lesion size does not matter BUT one of the lesions must
have HER2 positivity centrally-confirmed. If several lesions are found to be HER2
positive locally, the largest lesion should be considered for central review.
- Maximum cumulative dose of doxorubicin >360mg/m² or maximum cumulative dose of
epirubicin >720mg/m² or any prior anthracyclines unrelated to the present breast
cancer;
- (Neo-) or adjuvant chemotherapy using peripheral stem cell or bone marrow stem cell
support;
- Any prior mediastinal irradiation except internal mammary node irradiation for the
present breast cancer;
- Patients with positive or suspicious internal mammary nodes identified by sentinel
node technique which have not been irradiated or will not be irradiated, or patients
with supraclavicular lymph node involvement (confirmed by fine needle aspirate or
biopsy);
- Prior use of anti-HER2 therapy for any reason or other prior biologic or immunotherapy
for breast cancer;
- Concurrent anti-cancer treatment, except hormonal therapy or radiotherapy for the
present breast cancer;
- Concurrent anti-cancer treatment in another investigational trial with hormone therapy
or immunotherapy unless approved by the Executive Committee:
- Serious cardiac illness or medical conditions including but not confined to:
History of documented congestive heart failure (CHF) or systolic dysfunction (LVEF <50%);
High-risk uncontrolled arr
