[1] The ECOG score assesses how the disease affects a participant's daily living abilities. It ranges from 0-5, with 0 being the best and 5 being the worst outcome. "0" reflects a fully active participant, able to carry on all pre-disease performance without restriction. "1" reflects a participant restricted in physically strenuous activity but ambulatory and able to carry out work of a light or sedentary nature. "2" reflects an ambulatory participant, who is up and about more than 50% of waking hours, and capable of all self-care but unable to carry out any work activities.
[2] Number of participants randomized in the prior bevacizumab stratum as per the interactive voice response system (IVRS).



  Outcome Measures

1.  Primary:   Overall Survival (OS)   [ Time Frame: From the date of the first randomization until the study data cut-off date, 07 February 2011 (approximately three years) ]

2.  Secondary:   Progression-free Survival (PFS) Assessed by Independent Review Committee (IRC)   [ Time Frame: From the date of the first randomization until the occurrence of 561 OS events, 06 May 2010 (approximately 30 months) ]

3.  Secondary:   Overall Objective Response Rate (ORR) Based on the Tumor Assessment by the Independent Review Committee (IRC) as Per Response Evaluation Criteria in Solid Tumours (RECIST) Criteria   [ Time Frame: From the date of the first randomization until the study data cut-off date, 06 May 2010 (approximately 30 months) ]

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

5.  Secondary:   Immunogenicity Assessment: Number of Participants With Positive Sample(s) in the Anti-drug Antibodies (ADA) Assay and in the Neutralizing Anti-drug Antibodies (NAb) Assay   [ Time Frame: Baseline, every other treatment cycle, 30 days and 90 days after the last infusion of aflibercept/placebo ]
