Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Time to Progression (TTP)	Median time (in months) from randomisation until objective disease progression or death (in the absence of objective progression).	RECIST(Response Evaluation Criteria in Solid Tumors ) tumour assessments carried out every 12 weeks (+/- 2 weeks) from randomisation for study duration (48 months)
Secondary	Objective Response Rate (ORR)	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.	RECIST tumour assessments carried out every 12 weeks (+/- 2 weeks) from randomisation for study duration (48 months)
Secondary	Clinical Benefit Rate (CBR)	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.	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)
Secondary	Duration of Response (DoR)	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)	RECIST tumour assessments carried out every 12 weeks (+/- 2 weeks) from randomisation for study duration (48 months)
Secondary	Duration of Clinical Benefit (DoCB)	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	RECIST tumour assessments carried out every 12 weeks (+/- 2 weeks) from randomisation for study duration (48 months)
Secondary	Overall Survival (OS)	Median time (in months) from randomisation until death (from any cause) (analysis at 50% deaths )	Overall Survival is equivalent to time to death. For this endpoint, all deaths occurring for study duration (48 months)
Secondary	Change From Randomisation in Trial Outcome Index (TOI) Over the Course of the Study	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.	TOI questionnaires were completed every 4 weeks from randomisation until week 24 and then again at treatment discontinuation, for study duration (48 months)
Secondary	Overall Survival (OS) - Follow-up	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)	Median time (in months) from randomisation until death (from any cause),up to 80 months
