Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Overall Survival	Time from the date of randomization until death due to any cause	Survival contact from the date of randomization and then every 8 weeks following objective disease progression and in the 7 days following OS Data Cut off (DCO); Time point(s) at which outcome measure is assessed up to 4 years
Secondary	Progression-Free Survival (PFS)	Time from randomization until the date of objective radiological disease progression according to RECIST (v1.1) or death by any cause in the absence of progression. Objective progression is defined as at least a 20% increase in the sum of the diameters of the target lesions (compared to previous minimum sum) or an overall non-target lesion assessment of progression or a new lesion.	Scans taken at baseline and then follow up assessments taken every 8 weeks up to Week 40 and then every 16 weeks until objective disease progression as defined by RECIST 1.1, assessed up to 3 years
Secondary	Number of Patients With Objective Response.	Number of patients with objective response. Per RECIST 1.1, complete response (CR) is disappearance of all target lesions since baseline; partial response (PR) is at least a 30% decrease in the sum of the diameters of target lesions. Overall Response = CR + PR.	Scans taken at baseline and then follow up assessments taken every 8 weeks up to Week 40 and then every 16 weeks until objective disease progression as defined by RECIST 1.1, assessed up to 3 years
Secondary	Number of Patients Objective Response	Number of patients with objective response. Per RECIST 1.1, complete response (CR) is disappearance of all target lesions since baseline; partial response (PR) is at least a 30% decrease in the sum of the diameters of target lesions. Overall Response = CR + PR.	Scans taken at baseline and then follow up assessments taken every 8 weeks up to Week 40 and then every 16 weeks until objective disease progression as defined by RECIST 1.1, assessed up to 3 years
Secondary	Number of Patients With Deterioration of Health Related Quality of Life (HRQoL) as Assessed by the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Questionnaire Core 30 Item Module (QLQ-C30) Global HRQoL Scale	Number of patients with a clinically important deterioration in the global HRQoL score or death by any cause in the absence of a clincially meaningful symptom deterioration	Pre-treatment , Day 29 and then every 4 weeks until discontinuation, assessed up to 3 years
Secondary	Time to Response	Time from randomization to the first onset of a confirmed objective tumour response	Scans taken at baseline and then follow up assessments taken every 8 weeks up to Week 40 and then every 16 weeks until objective disease progression as defined by RECIST 1.1, assessed up to 3 years
Secondary	Duration of Response	Time from the first documentation of CR/PR until the date of progression, or the last evaluable RECIST assessment for patients taht do not progress or progress after two or more missed visits	Scans taken at baseline and then follow up assessments taken every 8 weeks up to Week 40 and then every 16 weeks until objective disease progression as defined by RECIST 1.1, assessed up to 3 years
