Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: 1

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Progression Free Survival (PFS)
Time Frame: Radiologic scans performed at weeks 9 and 18 (+/-1 week) and every 12 weeks thereafter relative to the date of randomisation until the primary analysis (approximately 20 months)
PFS (based on independent central review) was defined as the time from randomisation until objective disease progression as defined by Response Evaluation Criteria In Solid Tumours (RECIST) v1.1 (≥20% increase in the sum of the diameters of target lesions from minimum, clinically significant progression in non-target lesions or the presence of a new lesion) or death (by any cause in the absence of progression).
Radiologic scans performed at weeks 9 and 18 (+/-1 week) and every 12 weeks thereafter relative to the date of randomisation until the primary analysis (approximately 20 months)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage Change in Tumour Size
Time Frame: Week 9 (+/- 1 week)
The total tumour size was defined as the sum of the longest diameters of the target lesions. At week 9, the percentage change in tumour size was calculated as [(week 9 sum of target lesions - baseline sum of target lesions)/baseline sum of target lesions]*100 for each patient. Imputations were used for missing data where possible.
Week 9 (+/- 1 week)
Overall Survival (OS)
Time Frame: Following disease progression, patients will be contacted every 12 weeks to assess survival status until the final analysis (approximately 50 months)
OS was defined as the time from randomisation until death by any cause. Patients who had not died at the time of analysis were censored at the last date the patient was known to be alive. Updated OS based on final OS analysis (DCO 31 January 2014)
Following disease progression, patients will be contacted every 12 weeks to assess survival status until the final analysis (approximately 50 months)
