- Primary Outcome Measures
Name Time Method Progression Free Survival (PFS) in the Overall Study Population Tumour assessments were carried out 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 maximum up to 27 months PFS is defined as the time from randomisation till objective progression or death. In absence of progression or death, the time is calculated from randomisation till last evaluable scanning visit.
Progression Free Survival (PFS) in Patients With Tumours Defined as Homologous Recombination Deficient by Loss of Ataxia-Telangiectasia Mutation (ATM) Protein [ATM Negative Patients] Tumour assessments are carried out 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 maximum up to 27 months PFS is defined as the time from randomisation till objective progression or death. In absence of progression or death, the time is calculated from randomisation till last evaluable scanning visit.
- Secondary Outcome Measures
Name Time Method Time to Deterioration in QoL Fatigue Score in the Overall Study Population Questionnaire data collected at Baseline ie on or before date of randomisation, every 4 weeks post baseline, assessed maximum up to 27 months Time calculated from randomisation till worsening of fatigue score based on European Organisation for Research and Treatment of Cancer (EORTC) questionnaire data
Overall Survival (OS) in ATM Negative Patients Survival follow up from randomisation till death of the patient or till end of study in absence of death, assessed maximum up to 27 months Overall survival is defined as the duration from randomisation till death. In absence of death, the time is calculated from randomisation till the date subject last known to be alive.
Objective Response Rate (ORR) in the Overall Study Population Tumour assessments carried out at baseline, 28 days before randomisation then every 8 weeks until week 40, after week 40 assessments will be carried out every 16 weeks until objective disease progression, assessed maximum up to 27 months Objective response rate is the proportion of patients with at least one measurable lesion at baseline, who experienced complete or partial response at least once during the assessment period, according to the definitions of Response Evaluation Criteria In Solid Tumours (RECIST version 1.1).
Objective Response Rate (ORR) in the ATM Negative Patients Tumour assessments carried out at baseline, 28 days before randomisation then every 8 weeks until week 40, after week 40 assessments will be carried out every 16 weeks until objective disease progression, assessed maximum up to 27 months Objective response rate is the proportion of ATM negative patients with at least one measurable lesion at baseline, who experienced complete or partial response at least once during the assessment period, according to the definitions of Response Evaluation Criteria In Solid Tumours (RECIST version 1.1).
Percentage Change in Tumour Size at Week 8 in the Overall Study Population Tumour scans done at Baseline and week 8 Percentage change in tumour size from baseline to Week 8 calculated as 100 X (week 8 tumour size - baseline tumour size) / (baseline tumour size)
Percentage Change in Tumour Size at Week 8 in the ATM Negative Patients Tumour scans done at Baseline and week 8 Percentage change in tumour size from baseline to Week 8 calculated as 100 X (week 8 tumour size - baseline tumour size) / (baseline tumour size)
Overall Survival (OS) in the Overall Study Population Survival follow up from randomisation till death of the patient or till end of study in absence of death, assessed maximum up to 27 months Overall survival is defined as the duration from randomisation till death. In absence of death, the time is calculated from randomisation till the date subject last known to be alive.
Time to Deterioration in Global Quality of Life (QoL) Score in the Overall Study Population Questionnaire data collected at Baseline ie on or before date of randomisation, every 4 weeks post baseline, assessed maximum up to 27 months Time calculated from randomisation till worsening of Global QoL score based on European Organisation for Research and Treatment of Cancer (EORTC) questionnaire data
Time to Deterioration in QoL Nausea & Vomiting Domain Score in the Overall Study Population Questionnaire data collected at Baseline ie on or before date of randomisation, every 4 weeks post baseline, assessed maximum up to 27 months Time calculated from randomisation till worsening of nausea \& vomiting domain score based on European Organisation for Research and Treatment of Cancer (EORTC) questionnaire data
Time to Deterioration in QoL Pain Domain Score in the Overall Study Population Questionnaire data collected at Baseline ie on or before date of randomisation, every 4 weeks post baseline, assessed maximum up to 27 months Time calculated from randomisation till worsening of pain domain score based on European Organisation for Research and Treatment of Cancer (EORTC) questionnaire data
Time to Deterioration in QoL Dysphagia Domain Score in the Overall Study Population Questionnaire data collected at Baseline ie on or before date of randomisation, every 4 weeks post baseline, assessed maximum up to 27 months Time calculated from randomisation till worsening of dysphagia domain score based on European Organisation for Research and Treatment of Cancer (EORTC) questionnaire data
