Primary Outcome Measures:
  • Time to Progression (TTP) [ Time Frame: RECIST tumour assessments carried out every 12 weeks (+/- 2 weeks) from randomisation for study duration (48 months) ] [ Designated as safety issue: No ]
    Median time (in months) from randomisation until objective disease progression or death (in the absence of objective progression).


Secondary Outcome Measures:
  • Objective Response Rate (ORR) [ Time Frame: RECIST tumour assessments carried out every 12 weeks (+/- 2 weeks) from randomisation for study duration (48 months) ] [ Designated as safety issue: No ]
    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.

  • 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) ] [ Designated as safety issue: No ]
    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.

  • Duration of Response (DoR) [ Time Frame: RECIST tumour assessments carried out every 12 weeks (+/- 2 weeks) from randomisation for study duration (48 months) ] [ Designated as safety issue: No ]
    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)

  • Duration of Clinical Benefit (DoCB) [ Time Frame: RECIST tumour assessments carried out every 12 weeks (+/- 2 weeks) from randomisation for study duration (48 months) ] [ Designated as safety issue: No ]
    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

  • Overall Survival (OS) [ Time Frame: Overall Survival is equivalent to time to death. For this endpoint, all deaths occurring for study duration (48 months) ] [ Designated as safety issue: No ]
    Median time (in months) from randomisation until death (from any cause)

  • Time to Deterioration in Trial Outcome Index (TOI) [ 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) ] [ Designated as safety issue: No ]
    Median time (in months) from randomisation until deterioration in TOI (defined as the first visit response of 'worsened') using the Kaplan-Meier method. Trial Outcome Index (TOI) is derived from the FACT-B questionnaire. Data were collected from a subgroup of patients.
