Brief Summary:
The purpose of this study is to see if Cediranib in combination with FOLFOX is effective in treating metastatic colorectal cancer and to see how it compares with Avastin (Bevacizumab) in combination with FOLFOX.

Condition or disease Intervention/treatment Phase
Colorectal Cancer Drug: Cediranib Drug: Bevacizumab Drug: 5-fluorouracil ( in FOLFOX) Drug: Leucovorin (in FOLFOX) Drug: Oxaliplatin (in FOLFOX) Phase 2 Phase 3

Primary Outcome Measures :
  1. Progression Free Survival [ Time Frame: Baseline then at Weeks 8, 16, 24 and then every 12 weeks until progression ]
    Progression is defined as the number of months from randomisation until progressive disease based on RECIST (progression of target lesions, clear progression of existing non-target lesions or the appearance of one or more new lesions) or death in the absence of progression.

Secondary Outcome Measures :
  1. Overall Survival [ Time Frame: Randomisation until data cut-off ]
    Number of months from randomisation to the date of death from any cause

  2. Objective Response Rate [ Time Frame: Up until data cut-off ]

    Objective response rate is Complete Response (CR) + Partial Response (PR) as defined below:

    CR = Disappearance of all target lesions. PR = At least a 30% decrease in the sum of longest diameters (LDs) of target lesions, taking as reference the baseline sum of LDs.

  3. Duration of Response [ Time Frame: Up until data cut-off date of 15/11/2007 ]
    Duration of Response is calculated as the time from the first recording of CR/PR until the patient progresses, regardless of whether the patient was still taking study medication. Only confirmed responses are included in the calculation. For patients who had not progressed, the end date used in the calculation of duration of response is the data cut-off date of 15th November 2009.

  4. Percentage Change in Tumour Size [ Time Frame: Baseline to Week 8 ]
    Percentage change in tumour size from baseline to first RECIST assessment (Week 8) ((Week 8 - baseline)/baseline)*100

  5. Time to Worsening of Health Related Quality of Life (QOL) Based on the FACT Colorectal Symptom Index (FCSI) [ Time Frame: Baseline through to data cut-off ]
    Time to worsening of symptoms, as measured by the FACT colorectal symptom index (FCSI), will be defined as the time when a sustained clinically important deterioration in the total score from the FCSI has been recorded.
