TRUQAP + Fulvestrant QoL Score Graph TRUQAP + Fulvestrant QoL Score Graph

Line graph depicting the LS mean change from baseline in EORTC QLQ-C30 GHS/QoL score in patients with PIK3CA, AKT1, or PTEN alterations for TRUQAP + fulvestrant (n=139) and fulvestrant alone (n=114). A clinically meaningful worsening from baseline was predefined in the statistical analysis as a decrease of ≥10 points.

Analyses are descriptive only. CAPItello-291 was not designed to assess statistical significance for patient-reported QoL. Results should be interpreted with caution.1,2

In CAPItello-291, QoL was assessed using the EORTC QLQ-C302
EORTC QLQ-C30 is an integrated questionnaire for assessing HRQoL of cancer patients participating in clinical trials using a scale of 0 to 100, with high scores representing high or healthy levels of functioning/high QoL.
  • The questionnaire comprises a 2-item scale with 5 functional domains (physical, role, cognitive, emotional, and social), 3 symptom domains (fatigue, pain, and nausea and vomiting), and 5 individual item symptom scores (dyspnea, insomnia, appetite loss, constipation, and diarrhea)
  • Patients completed the EORTC QLQ-C30 at baseline, and every 4 weeks until second progression, and at discontinuation of trial treatment
    • Baseline was defined as the first assessment collected on cycle 1, day 1, before the start of study treatment
  • Time to deterioration (TTD) was defined as the time from randomization to first occurrence of ≥10-point worsening in EORTC QLQ-C30 score
    • TTD was 18.5 months (95% CI: 12.9-NR) with TRUQAP + fulvestrant (n=138) and 13.8 months (95% CI: 7.4-NR) with fulvestrant alone (n=113); HR=0.62 (95% CI: 0.39-0.98)
  • Limitations: The EORTC QLQ-C30 is not all-inclusive and does not include adequate assessment of additional, expected treatment-related symptoms or overall side effect bother from the patient perspective

*Error bars represent 95% CIs. Includes all randomly assigned patients with an evaluable baseline assessment and at least one evaluable post-baseline assessment. Only on-treatment assessments were included. Data are presented for cycles where there were at least 20 events in each treatment group.2

Least squares mean change from baseline of ≥10 indicates a clinically meaningful change.2
