Abstract 94MO

Background

In the FLIPPER trial, FUL/PAL significantly improved progression-free survival (PFS) compared to FUL/PBO as first-line in patients (pts) with HR+/HER2- endocrine sensitive ABC. Here we present patient-reported outcome (PRO) results including health-related QoL (HRQoL).

Methods

Pts were randomized (1:1); 94 FUL/PAL, 95 FUL/PBO. PROs were evaluated at baseline (BL), every three cycles and at end of treatment using the EORTC QLQ-C30 and QLQ-BR23 questionnaires; 178 pts (94.2%) completed BL and ≥1 post-BL PROs. For functional and global health status (GHS)/QoL scales, higher scores represent better level of functioning or QoL and for symptom scales, worse symptoms. Time to deterioration (TTD) in GHS/QoL score considered ≥ 10points. Changes from BL and TTD were analysed using linear mixed-effect and Cox regression models, respectively.

Results

Questionnaire completion rates were high (>95%) for the first 22 cycles. BL scores were comparable between the two treatment arms. Significant between-arm differences were observed in overall change from BL of GHS/QoL, appetite loss, constipation and systemic therapy side effect scores favouring FUL/PBO. No other statistically significant differences were found between arms for the remaining functional and symptom scales. Median TTD in GHS/QoL was delayed in FUL/PBOL [30.3 months (mo)] vs. FUL/PAL (11.1 mo) [adjusted HR (aHR) 1.57, 95% CI 1.03-2.39, p=0.036]; TTD in GHS/QoL was delayed in PBO-treated pts without progressive disease (PD) (aHR 2.0, 95% CI 1.1-3.8, p=0.023) but not in pts with PD (aHR 1.2, 95% CI 0.6-2.2, p=0.658). No statistically significant differences in TTD were found for the other QLQ-C30 and QLQ-BR23 scales.

Conclusions

The TTD in GHS/QoL was prolonged with FUL/PBO, however, GHS/QoL was improved numerically in both arms. The overall HRQoL differences favouring FUL/PBO were clinically meaningful only for appetite loss. These results together with the improvement of PFS observed with FUL/PAL make of this a beneficial therapeutic option for these patients.
