E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
1-To evaluate the efficacy, as measured by PFS, of FOLFIRI + MEHD7945A (administered every 2 weeks) versus FOLFIRI + cetuximab (administered weekly) in patients with KRAS wild-type mCRC
2- To evaluate the efficacy, as measured by PFS, of FOLFIRI + MEHD7945A (administered every 2 weeks) versus FOLFIRI + cetuximab (administered weekly) in patients with KRAS wild-type mCRC whose tumors express low levels of HER3

|
E.2.2 | Secondary objectives of the trial |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint for this study is PFS which will be determined for all patients and for subset of biomarker-positive patients with Kras wild type mCRC. PFS is defined as the time from randomization to documented disease progression assessed by the investigator or death on study, whichever occurs first. |

•Incidence, nature, and severity of adverse events, graded according to the NCI CTCAE v4.0
•Clinically significant changes in vital signs, physical findings, and clinical laboratory results during and following administration of study treatment
•MEHD7945A minimum (Cmin) and maximum (Cmax) serum concentration prior to and after infusion at select time points for patients on Arm A
•Plasma concentrations of 5-FU, irinotecan, and SN-38 prior to and after infusion at select time points for patients on Arm A
