Measure Type Secondary
Measure Title Number of Participants With Treatment-emergent Adverse Events (TEAE)
Measure Description Summary of treatment-emergent adverse events in the safety population. The National Cancer Institute Common Terminology Criteria for Adverse Event (NCI-CTCAE), version 3.0 was used in this study to grade the severity of AEs.
Time Frame From the date of the first randomization up to 30 days after the treatment discontinuation or until TEAE was resolved or stabilized  
Safety Issue Yes  

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.
Of the total 235 patients included in the safety population, 116 patients received mFOLFOX6 and 119 patients received mFOLFOX6 + aflibercept. One patient, randomly assigned to the mFOLFOX6 arm did not receive any study treatment and was therefore excluded from the safety analyses.

Certain Agreements:  
Principal Investigators are NOT employed by the organization sponsoring the study.
There IS an agreement between Principal Investigators and the Sponsor (or its agents) that restricts the PI's rights to discuss or publish trial results after the trial is completed.
The agreement is:
unchecked The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release and can embargo communications regarding trial results for a period that is less than or equal to 60 days. The sponsor cannot require changes to the communication and cannot extend the embargo.
unchecked The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release and can embargo communications regarding trial results for a period that is more than 60 days but less than or equal to 180 days. The sponsor cannot require changes to the communication and cannot extend the embargo.


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.
