To compare progression-free survival (PFS) based on tumor assessments by an independent review facility (IRF) between patients in the two treatment arms. |
|
E.2.2 | Secondary objectives of the trial |
• To compare overall survival (OS) between the two treatment arms • To compare PFS between the two treatment arms based upon investigator assessment of progression • To compare the overall objective response rate between the two treatment arms • To compare the duration of objective response between the two treatment arms • To compare the safety profile between the two treatment arms • To compare time to symptom progression, as assessed by the FACT Trial Outcome Index - Physical Functional Breast (TOI-PFB) • To evaluate if biomarkers from tumor tissues or blood samples (e.g., HER3 expression, Fc gamma, and serum ECD/HER2 and/or HER ligands concentrations) correlate with clinical outcomes

E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
1. DNA REPOSITORY SUBSTUDY IN ASSOCIATION WITH PERTUZUMAB STUDY TOC4129g/WO20698. Protcocol no. TOC4129g/WO20698 (Substudy 1), dated 7-Sep-07. The primary objective of this study is to perform exploratory analyses to generate hypotheses identifying genes associated with treatment response, toxicity, or disease risk. If such genetic hypotheses are identified, they may be tested in future clinical studies within this therapeutic area. This study is optional and a separate Informed Consent will be required.
Biomarker Sample Repository ( optional), included in main protocol version B dated 2007-12-12: The collected blood samples may be used to develop and validate diagnostic assays and allow the generation of statistically meaningful biomarker data related to HER2-positive breast cancer disease or response to pertuzumab and/or trastuzumab.
Metastatic tumor tissue samples for biomarker analysis ( optional), included in main protocol version B dated 2007-12-12: assessment of tumor tissue biomarkers for pertuzumab/trastuzumab response prediction. |

E.3 | Principal inclusion criteria |
Disease specific inclusion criteria: 1. Histologically or cytologically confirmed adenocarcinoma of the breast with locally recurrent or metastatic disease, and candidate for chemotherapy. Patients with measurable and nonmeasurable lesion are eligible. Locally recurrent disease must not be amenable to resection with curative intent. Note: Patients with de-novo Stage IV disease are eligible. 2. HER2-positive (defined as 3+ IHC or FISH amplification ratio ≥ 2.0 ) MBC confirmed by a Sponsor-designated central laboratory. It is strongly recommended that a formalin-fixed paraffin-embedded (FFPE) tissue block from the primary tumor be submitted for central laboratory confirmation of HER2 eligibility; however, if that is not possible, 25 unstained and freshly cut slides will be submitted. (Tissue will subsequently be used for assessment of biomarkers.)
General inclusion criteria: 3. Age ≥ 18 years 4. Left Ventricular Ejection Fraction (LVEF) ≥ 50% at baseline (within 42 days of randomization) as determined by either ECHO or MUGA (ECHO is the preferred method. If the patient is randomized, the same method of LVEF assessment, ECHO or MUGA, must be used throughout the study, and to the extent possible, be obtained at the same institution) (see Section 7.4.2 of the protocol, page 98). All pre-study LVEF values during and post-trastuzumab adjuvant treatment for patients who received such adjuvant therapy prior to enrollment into the study will be collected. 5. Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0 or 1 6. For women of childbearing potential, agreement to use an effective form of contraception (patient and/or partner, e.g., surgical sterilization, a reliable barrier method [condoms, diaphragm], intrauterine devices, or abstinence) and to continue its use for the duration of study treatment and for 6 months after the last dose of study treatment7. Signed, written informed consent (approved by the Institutional Review Board or Independent Ethics Committee) obtained prior to any study procedure.

E.4 | Principal exclusion criteria |
Cancer Related Exclusion Criteria: 1. History of anticancer therapy for MBC (with the exception of one prior hormonal regimen for MBC). This includes any EGFR or anti-HER2 agents or vaccines, cytotoxic chemotherapy, or more than one prior hormonal regimen for MBC. 2. History of approved or investigative tyrosine kinase/HER inhibitors for breast cancer in any treatment setting, except trastuzumab used in the neoadjuvant or adjuvant setting 3. History of systemic breast cancer treatment in the neo-adjuvant or adjuvant setting with a disease-free interval from completion of the systemic treatment (excluding hormonal therapy) to metastatic diagnosis of < 12 months 4.

Hematological, Biochemical, and Organ Function 9. Current uncontrolled hypertension (systolic > 150 mmHg and/or diastolic > 100 mmHg) or unstable angina 10. History of CHF of any New York Heart Association (NYHA) criteria, or serious cardiac arrhythmia requiring treatment (exception, atrial fibrillation, paroxysmal supraventricular tachycardia) 11. History of myocardial infarction within 6 months of randomization 12. History of LVEF decline to below 50% during or after prior trastuzumab neo-adjuvant or adjuvant therapy 13. Current dyspnea at rest due to complications of advanced malignancy, or other diseases that require continuous oxygen therapy
General Exclusion Criteria 14. Inadequate organ function, evidenced by the following laboratory results within 28 days prior to randomization: •Absolute neutrophil count < 1,500 cells/mm3 •Platelet count < 100,000 cells/mm3 •Hemoglobin < 9 g/dL •Total bilirubin > upper limit of normal (ULN) (unless the patient has documented Gilbert’s syndrome) •SGOT (AST) and SGPT (ALT) > 2.5 x ULN •SGOT (AST) or SGPT (ALT) > 1.5 x ULN with concurrent serum alkaline phosphatase > 2.5 x ULN (unless bone metastases are present) •Serum creatinine > 2.0 mg/dL or 177 μmol/L •International normalized ratio (INR) and activated partial thromboplastin time (aPTT) > 1.5 x ULN (unless on therapeutic coagulation) 15. Current severe, uncontrolled systemic disease (e.g., clinically significant cardiovascular, pulmonary, or metabolic disease; wound healing disorders; ulcers; or bone fractures) 16. Major surgical procedure or significant traumatic injury within 28 days prior to study treatment start or anticipation of the need for major surgery during the course of study treatment 17. Pregnant or lactating women 18. History of receiving any investigational treatment within 28 days of randomization 19. Current known infection with HIV, HBV, or HCV 20.

E.5 End points |
E.5.1 | Primary end point(s) |
Progression-free survival (PFS) based on Independent Review Facility (IRF) evaluations. PFS is defined as the time from randomization to the first documented radiographical progressive disease, as determined by the IRF using RECIST (Therasse et al. 2000), or death from any cause, whichever occurs first. Carcinomatous meningitis diagnosed by cytologic evaluation of cerebral spinal fluid will also define progressive disease. |
