What was measured

The EORTC QLQ-C30 is a questionnaire that includes 5 functional scales, 3 symptom scales, 1 GHS/QoL scale, and 6 single items. GHS/QoL scale score ranges between 0 and 100. A high score for GHS/QoL represents better functioning or QoL.The change from baseline in the GHS/QoL score was assessed. A positive change from baseline indicated improvement. For each cohort, this analysis only included assessments up to the time point where there were at least 10 patients on each of the 2 treatment groups.

Analysis population: Randomized participants with baseline scores and at least one non-missing post-baseline assessment. Number analyzed refers to the number of participants with an evaluable value at the specified time point

Groups in this outcome

PIK3CA Mutant Cohort by Tumor Tissue: Alpelisib + Fulvestrant

Subjects with advanced breast cancer with a PIK3CA mutation (based on central testing of hotspot-mutations in tumor tissue) treated with alpelisib (300 mg; oral; once daily) in combination with fulvestrant (500 mg; intramuscular injection on Day 1 and Day 15 of Cycle 1, and then Day 1 of each subsequent 28-day cycle)

PIK3CA Mutant Cohort by Tumor Tissue: Placebo + Fulvestrant

Subjects with advanced breast cancer with a PIK3CA mutation (based on central testing of hotspot-mutations in tumor tissue) treated with placebo (300 mg; oral; once daily) in combination with fulvestrant (500 mg; intramuscular injection on Day 1 and Day 15 of Cycle 1, and then Day 1 of each subsequent 28-day cycle)

PIK3CA Non-mutant Cohort by Tumor Tissue: Alpelisib + Fulvestrant

Subjects with advanced breast cancer without a PIK3CA mutation (based on central testing of hotspot-mutations in tumor tissue) treated with alpelisib (300 mg; oral; once daily) in combination with fulvestrant (500 mg; intramuscular injection on Day 1 and Day 15 of Cycle 1, and then Day 1 of each subsequent 28-day cycle)

PIK3CA Non-mutant Cohort by Tumor Tissue: Placebo + Fulvestrant

Subjects with advanced breast cancer without a PIK3CA mutation (based on central testing of hotspot-mutations in tumor tissue) treated with placebo (300 mg; oral; once daily) in combination with fulvestrant (500 mg; intramuscular injection on Day 1 and Day 15 of Cycle 1, and then Day 1 of each subsequent 28-day cycle)
