E.5 End points |
E.5.1 | Primary end point(s) |
Overall Survival (OS), defined as the time from the date of randomisation until death of any cause. If a patient is alive at the database cut-off date, then the patient will be censored at the last date of follow-up. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Time from the date of randomisation until death of any cause. |
|
E.5.2 | Secondary end point(s) |
• The efficacy will be assessed using the following endpoints (tumour response assessed by RECIST v1.1): -Overall survival rates at 6 and 12 months, estimated by the Kaplan-Meier method. -Progression-free survival (PFS), defined as the time from the date of randomisation to date of disease progression (radiological or clinical) or death of any cause, whichever occurs first. Patients without tumour progression or death at the time of analysis will be censored at the date of their last tumour assessment. -PFS rates at 3 and 6 months, estimated by the Kaplan-Meier method -Disease control rate (DCR), defined as the percentage of patients, with complete response (CR), partial response (PR), or stable disease (SD) as best response at the database cut-off date. -Objective response rate (ORR), defined as the percentage of patients with CR or PR. Patients who discontinue treatment without a tumour assessment will be considered non-responders for the analysis. • Frequency and severity of adverse events assessed by NCI CTCAE v5.0 • Health-related quality of life will be assessed using the EORTC QLQ-C30 and the oesophago-gastric cancer questionnaire (EORTC QLQ-OG25) • Pharmacokinetic study of regorafenib and its metabolites M2 and M5, as well as that of irinotecan and SN-38 • Pharmacogenetic study of the impact of cyclin D1 polymorphisms • Immunochemistry analyses to identify tumour factors predictive of response to regorafenib and irinotecan combination
