1.  Primary:   Progression Free Survival (PFS) Rate at 12 Months   [ Time Frame: 12 months ]

Measure Type Secondary
Measure Title Progression Free Survival (PFS)
Measure Description

PFS was defined as the time from the date of randomization to the date of tumor progression or death from any cause, whichever occurred first. PFS was based on tumor assessment by the Independent Review Committee (IRC). PFS was estimated from Kaplan-Meier Curves.

The study was not powered for comparison of PFS between the two arms (non-comparative, open-label study).

Progression was defined using Response Evaluation Criteria In Solid Tumors (RECIST v1.0), as at least a 20 percent increase in the sum of the longest diameter (LD) of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions and/or unequivocal progression of existing non target-lesions.

Time Frame From the date of the first randomization until the study data cut-off date, 14 April 2011 (approximately 26 months)  

Population Description
Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
Evaluable patient (EP) population. A total of 55 patients (32 in the mFOLFOX6 group and 23 in the mFOLFOX6 + aflibercept group) were without an event at the cutoff date for the PFS analysis by IRC.

3.  Secondary:   Overall Objective Response Rate (ORR)   [ Time Frame: From the date of the first randomization until the study data cut-off date, 14 April 2011 (approximately 26 months) ]

4.  Secondary:   Overall Survival (OS)   [ Time Frame: From the date of the first randomization until the study data cut-off date, 14 April 2011 (approximately 26 months) ]

5.  Secondary:   Number of Participants With Treatment-emergent Adverse Events (TEAE)   [ Time Frame: From the date of the first randomization up to 30 days after the treatment discontinuation or until TEAE was resolved or stabilized ]

6.  Secondary:   Immunogenicity of Intravenous (IV) Aflibercept   [ Time Frame: Any time post baseline and 90 days after the last infusion of aflibercept, according to baseline status ]

  Limitations and Caveats
  Hide Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
The overall survival (OS) data are severely limited due to the low number of events (<50%) in both arms, therefore median OS cannot be accurately estimated due to limitations of available data.
