E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The objective of this phase 2 study is to evaluate the antitumor activity, safety, and tolerability of sorafenib versus placebo when used in combination with mFOLFOX6 (5-fluorouracil [5-FU], levo-leucovorin [LLV], and oxaliplatin) in subjects with mCRC who have not been previously treated for Stage IV disease.
The primary efficacy objective is to compare progression-free survival (PFS) in subjects receiving sorafenib in combination with mFOLFOX6 versus subjects receiving placebo in combination with mFOLFOX6.
|
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives are to compare the treatment groups in terms of: • Overall survival (OS) • Time to progression (TTP) • Overall response rate (ORR) • Duration of overall response (OR) • Safety and tolerability

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint is PFS, which will be measured from the date of randomization to the date of first observed progressive disease (PD, radiological or clinical, whichever is earlier) or the date of death due to any cause (if occurring before progression). For subjects without documented progression or death at the time of analysis, the PFS will be censored at the last date of tumor assessment. If a subject has no tumor assessments after Baseline, then the subject will be censored at Day 1. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Will be measured from the date of randomization to the date of first observed progressive disease (PD, radiological or clinical, whichever is earlier) or the date of death due to any cause (if occurring before progression) |
|
E.5.2 | Secondary end point(s) |
- Overall survival - Time to progression - Overall response rate - Duration of overall response |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Overall survival will be measured from the date of randomization to death due to any cause.
Time to progression will be measured from the date of randomization to the date of first observed PD (radiological or clinical, whichever is earlier).
Duration of OR will be measured from the date of the first documentation of PR or CR (whichever status is recorded first) to the first date that PD or death due to any cause is documented. |
