5.Secondary Outcome
Title Quality of Life (QoL): Change From Baseline in European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) of Global Health Status /Quality of Life (GHS/QoL) and Physical Functioning Scales
Hide Description EORTC QLQ-C30 is a 30-question tool used to assess the overall QoL in cancer participants. It consisted of 15 domains: 1 GHS/QoL scale, 5 functional scales (Physical, role, cognitive, emotional, social), and 9 symptom scales/items (Fatigue, nausea and vomiting, pain, dyspnea, sleep disturbance, appetite loss, constipation, diarrhea, financial impact). Most items are scored 1 ("not at all") to 4 ("very much") except for the items contributing to the GHS/QoL, which are scored 1 ("very poor") to 7 ("excellent"). A linear transformation was applied to the raw scores so that all transformed scores lie between 0 to 100. For the GHS/QoL and 5 functional scales a high score indicates better global health status/functioning and a negative change from baseline indicated less improvement. For the symptom scales, a high score indicates a higher level of symptoms, and a negative change from baseline indicated an improvement in symptoms.

Hide Description An adverse event (AE) was defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. A TEAE was defined as those that are not present at baseline or represent the exacerbation of a pre-existing condition during the on-treatment period. 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 TEAEs. Number of participants with TEAEs, serious TEAEs, and TEAEs leading to death were reported.
