Colorectal Cancer Metastatic

Any untoward medical occurrence in a participant who received investigational medicinal product (IMP) was considered an AE without regard to possibility of causal relationship with this treatment. Treatment-emergent adverse events (TEAEs) were defined as AEs that developed or worsened or became serious during on-treatment period. On-treatment period was defined as the time from the first dose of treatment to 30 days after the last dose of treatment (either Aflibercept or FOLFIRI). A serious adverse event (SAE) was defined as any untoward medical occurrence that resulted in any of the following outcomes: death, life-threatening, required initial or prolonged in-patient hospitalization, persistent or significant disability/incapacity, congenital anomaly/birth defect, or considered as medically important event. Any TEAE included participants with both serious and non-serious AEs.

Time frame: Baseline upto 30 days after the last treatment administration (either Aflibercept or FOLFIRI whichever comes last) (maximum exposure:723 days)

Population: Safety population defined as the participants who signed the informed consent form and received at least part of one dose of study treatment.

EORTC-QLQ-C30 is a cancer-specific instrument with 30 questions for evaluation of new chemotherapy and provides an assessment of participant reported outcome dimensions. First 28 questions used 4-point scale (1=not at all,2=a little,3=quite a bit,4=very much) for evaluating 5 functional scales (physical,role,emotional,cognitive,social), 3 symptom scales (fatigue,nausea/vomiting,pain) & other single items. For each item,high score represented high level of symptomatology/problem. Last 2 questions represented participant's assessment of overall health & quality of life, coded on 7-point scale (1=very poor to 7=excellent). EORTC QLQ-C30 observed values and change from baseline for global health status (scoring of questions 29 & 30) and 5 functional scales, 3 symptom scales and other single items (scoring of questions 1 to 28). Answers were converted into grading scale, with values between 0 and 100. A high score represented a favorable outcome with a best quality of life for participant.

Time frame: Pre-dose at Baseline, Day 1 of every odd cycle; and at end of treatment (30 days after last study treatment) (maximum exposure: 99 weeks)

Population: EORTC QLQ-C30 analysis population: participants who signed informed consent form; had an evaluable QLQ-C30 questionnaire at baseline and at least one evaluable assessment post baseline and received at least part of one dose of study treatment(either Aflibercept or FOLFIRI).Here, n=number of participants with available data at specified time-points.

EQ-5D VAS was used to record a participant's rating for his/her current health-related quality of life state and captured on a vertical VAS (0-100), where 0 = worst imaginable health state and 100 = best imaginable health state. Baseline corresponded to last evaluable assessment before treatment administration.

Time frame: Pre-dose at Baseline, Day 1 of every odd cycle; and at end of treatment (30 days after last study treatment) (maximum exposure: 99 weeks)

Population: EQ-5D analysis population: participants who signed informed consent form, had an evaluable EQ-5D questionnaire at baseline and at least one evaluable assessment post baseline and received at least part of one dose of study treatment (either Aflibercept or FOLFIRI).Here, n = number of participants with available data at specified time-points.

EQ-5D was a standardized HRQL questionnaire consisting of EQ-5D descriptive system and Visual Analogue Scale (VAS). EQ-5D descriptive system comprised of 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression measured on 3 levels (no problem, some problems & severe problems) within a particular EQ-5D dimension. 5 dimensional 3-level system was converted into single index utility score. Possible values for single index utility score ranged from -0.594 (severe problems in all dimensions) to 1.0 (no problem in all dimensions) on scale where 1 represented best possible health state.

Time frame: Pre-dose at Baseline, Day 1 of every odd cycle; and at end of treatment (30 days after last study treatment) (maximum exposure: 99 weeks)

Population: EQ-5D analysis population: participants who signed informed consent form, had an evaluable EQ-5D questionnaire at baseline and at least one evaluable assessment post baseline and received at least part of one dose of study treatment (either Aflibercept or FOLFIRI).Here, n = number of participants with available data at specified time-points.
