Primary Outcome Measures :
  1. Time to Progression (TTP) [ Time Frame: RECIST(Response Evaluation Criteria in Solid Tumors ) tumour assessments carried out every 12 weeks (+/- 2 weeks) from randomisation for study duration (48 months) ]
    Median time (in months) from randomisation until objective disease progression or death (in the absence of objective progression).


Secondary Outcome Measures :
  1. Objective Response Rate (ORR) [ Time Frame: RECIST tumour assessments carried out every 12 weeks (+/- 2 weeks) from randomisation for study duration (48 months) ]
    Using the RECIST scan data, an objective response (OR) is defined as a patient having a best overall response of either complete response (CR) or partial response (PR) which is subsequently confirmed as per RECIST. ORR is defined as the percentage of patients with OR.

  2. Clinical Benefit Rate (CBR) [ Time Frame: Clinical Benefit from the sequence of RECIST scan data for study duration (48 months) . RECIST (Response Evaluation Criteria in Solid Tumours) scans were performed every 12 weeks (+/- 2 weeks) from randomisation for study duration (48 months) ]
    A Clinical Benefit (CB) responder is defined as a patient having a best overall response of CR, PR or SD (stable disease) >=24 weeks. The Clinical Benefit Rate is the percentage of patients with CB.

  3. Duration of Response (DoR) [ Time Frame: RECIST tumour assessments carried out every 12 weeks (+/- 2 weeks) from randomisation for study duration (48 months) ]
    Time from randomisation until objective progression or death (in the absence of objective progression), measured only in those patients who achieve a confirmed complete response (CR) or confirmed partial response (PR)

  4. Duration of Clinical Benefit (DoCB) [ Time Frame: RECIST tumour assessments carried out every 12 weeks (+/- 2 weeks) from randomisation for study duration (48 months) ]
    Time from randomisation until objective progression or death (in the absence of objective progression), measured only in those patients who achieve a confirmed complete response (CR), confirmed partial response (PR), or stable disease (SD) >=24 weeks

  5. Overall Survival (OS) [ Time Frame: Overall Survival is equivalent to time to death. For this endpoint, all deaths occurring for study duration (48 months) ]
    Median time (in months) from randomisation until death (from any cause) (analysis at 50% deaths )

  6. Change From Randomisation in Trial Outcome Index (TOI) Over the Course of the Study [ Time Frame: TOI questionnaires were completed every 4 weeks from randomisation until week 24 and then again at treatment discontinuation, for study duration (48 months) ]
    Mean (and standard deviation) change from randomisation until treatment discontinuation in TOI (defined as the first visit response of 'worsened' which is a decrease in TOI from baseline of 5 points or more) using the Kaplan-Meier method. If a subject has not shown a reduction of 5 points or more at the time of analysis then the observation will be right censored using the last QOL assessment date. Trial Outcome Index (TOI) is derived from the FACT-B questionnaire (Cella et al, 1993) by adding together the scores from the following 3 subscales; Physical well-being (PWB), Functional well-being (FWB) and Breast cancer subscale (BCS). The TOI score range is 0-92 with the higher scores representing the more favourable outcomes. Data were collected from a subgroup of patients.

  7. Overall Survival (OS) - Follow-up [ Time Frame: Median time (in months) from randomisation until death (from any cause),up to 80 months ]
    Overall Survival is equivalent to time to death. For this endpoint, all deaths occurring during the study as a whole until the data cut-off for the survival extension (31st October 2011) are presented (analysis at 75% deaths)
