139PD - Patient-reported outcomes from FLAURA: Osimertinib versus standard of care (SoC) epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) in patients with EGFR-mutated advanced non-small cell lung cancer (NSCLC) (ID 396)
07:45 - 09:00 | Author(s): N. Karaseva
In the phase 3 FLAURA trial (N = 556), osimertinib demonstrated superior efficacy to SoC EGFR-TKI as first-line treatment of EGFR mutation-positive advanced NSCLC.
Patients in FLAURA completed the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 items (QLQ-C30) at baseline and then every 6 weeks, and Lung Cancer 13 items (QLQ-LC13) at baseline, then weekly for 6 weeks followed by every 3 weeks. Scores range from 0 to 100; higher scores represent greater symptom burden. A ≥10-point difference is considered clinically relevant. Pre-specified key symptoms were cough, dyspnoea, chest pain, appetite loss and fatigue.
Compliance with completing the questionnaire was ≥60% at all time points in both treatment arms. Baseline mean scores were similar in the osimertinib and SoC arms for cough (32.8 vs 33.5), dyspnoea (22.5 vs 25.0), chest pain (19.5 vs 20.8), appetite loss (22.7 vs 25.6) and fatigue (32.2 vs 35.8). Key symptoms improved in both arms from baseline over the first 9 months, with no significant differences in least-squares mean changes between the osimertinib and SoC arm (Table). Improvements in cough were seen from week 1 and were maintained throughout the first 9 months in both arms. QLQ-C30 functional and global health/quality of life scores improved from baseline in both arms, with no clinically relevant differences. Additional analyses are ongoing, including statistical significance testing and time to deterioration.Table:Change from baseline over 9 months in key patient-reported symptoms
Adjusted mean and estimated treatment differences obtained from a mixed-effects model for repeated measures. Model included patient (as a random effect), treatment, visit (as fixed effect and repeated measure), and treatment-by-visit interaction as explanatory variables, and the baseline symptom score as a covariate along with the baseline symptom score by visit interaction. The covariance structure for repeated measurements within the same patient was specified as unstructured. CI, confidence interval.

Key patient-reported symptoms in the FLAURA trial improved in both treatment arms from baseline over 9 months. Improvements in cough in the two arms were clinically relevant. Soria JC et al. N Engl J Med doi: 10.1056/NEJMoa1713137.
