E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To estimate the clinical benefit of MetMAb+bevacizumab+paclitaxel and MetMAb+placebo+paclitaxel relative to placebo + bevacizumab + paclitaxel, as measured by investigator-assessed PFS, in patients with metastatic or locally recurrent, triple-negative breast cancer who have received no prior systemic therapy or have progressed following first-line therapy for metastatic disease. |
|
E.2.2 | Secondary objectives of the trial |
• To evaluate OS benefit of MetMAb + bevacizumab + paclitaxel and MetMAb+placebo+paclitaxel relative to placebo + bevacizumab + paclitaxel in patients with metastatic or locally recurrent, triple-negative breast cancer who have received no prior systemic therapy or have progressed following first-line therapy • To characterize the safety and tolerability of MetMAb+bevacizumab+paclitaxel and MetMAb+placebo+paclitaxel relative to placebo+bevacizumab+paclitaxel • To evaluate drug exposure of MetMAb, paclitaxel, and bevacizumab • To evaluate the serum levels and incidence of anti-therapeutic antibodies (ATAs) against MetMAb • To evaluate the effect of MetMAb on the following ECG parameters: QTc interval, heart rate, uncorrected QT interval, PR interval, QRS duration, T-wave and U-wave morphology |

E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Protocol title: DNA REPOSITORY SUBSTUDY IN ASSOCIATION WITH METMAB STUDY OAM4861g Date and version: 13 May 2010, OAM4861g (DNA Substudy), version 1 Objectives: 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. |

E.5 End points |
E.5.1 | Primary end point(s) |
Kaplan–Meier methodology will be used to estimate the median PFS for each treatment arm. PFS is defined as the time from randomization to disease progression or relapse (as assessed by the site radiologist and/or investigator, using RECIST, Version 1.1) or death on study from any cause (defined as death within 30 days of the last study treatment), whichever occurs first. For patients who have not died or experienced disease progression at the end of study, PFS will be censored on the last date the patient was known to be progression free. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
The final analysis will occur when 126 PFS events have occurred. This analysis will occur in 2013. |
|
E.5.2 | Secondary end point(s) |
1) Objective response 2) Duration of response 3) Overall survival 4) Safety 5) PK results |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
The secondary endpoints will be evaluated at the time of the primary analysis |

|
The efficacy analyses will be performed when approximately 126 PFS events across all three treatment arms have occurred. Patients who are receiving onartuzumab or control treatment at the time of the final analysis who are considered by the treating physician to have benefitted will be allowed to continue onartuzumab or control treatment until disease progression, onset of treatment-limiting toxicity, or when the treating physician decides to discontinue the treatment, whichever occurs first. |
