290O – Patient-reported outcomes (PROs) in advanced breast cancer (ABC) treated with ribociclib + fulvestrant: results from MONALEESA-3

Speaker:
Peter A. Fasching (Erlangen, DE)

In the MONALEESA-3 trial (NCT02422615), ribociclib + fulvestrant significantly improved progression-free survival (PFS) vs placebo + fulvestrant in patients with hormone receptor-positive, human epidermal growth factor receptor 2-negative BC who had received no prior therapy or only 1 line of prior endocrine therapy for ABC.  This abstract presents PROs from the MONALEESA-3 trial including health-related quality of life (HRQoL).  According to the trial results, mean GHS/QLS (global health status/quality of life scale score of the EORTC QLQ-C30 questionnaire) was maintained or improved during every cycle of treatment in both arms.  Ribociclib + fluvestrant significantly prolonged PFS compared to placebo + fluvestrant while maintaining QoL.

291O – Ribociclib (RIB) + tamoxifen (TAM) or a non-steroidal aromatase inhibitor (NSAI) in premenopausal patients (pts) with hormone receptor-positive (HR+), HER2-negative (HER2–) advanced breast cancer (ABC): MONALEESA-7 patient-reported outcomes (PROs)

Speaker:
Nadia Harbeck (Munich, DE)

In the Phase III MONALEESA-7 trial (NCT02278120), RIB + TAM/NSAI + goserelin (GOS) significantly improved progression-free survival vs placebo (PBO) + TAM/NSAI + GOS in premenopausal pts with HR+, HER2– ABC.  This abstract features PRO updates from the MONALEESA-7 trial.  According to PROs, RIB + TAM/NSAI + GOS improves HRQoL and maintains functioning, work productivity, and activity in premenopausal pts with HR+, HER2– ABC. RIB + TAM/NSAI + GOS is also associated with a clinically meaningful reduction in pain vs PBO + TAM/NSAI + GOS.

292O – Patient-reported outcomes (PRO) in patients (pts) with advanced breast cancer and a germline BRCA1/2 mutation (gBRCAm) receiving talazoparib (TALA) vs physician’s choice chemotherapy treatment (PCT): a focus on the EMBRACA triple negative (TNBC) subpopulation

Speaker:
Hope S. Rugo (San Francisco, US)

One of the key subgroup analyses of the EMBRACA trial (a randomized 2:1 open-label phase 3 study) revealed a statistically significant improvement in progression-free survival (PFS) with TALA vs PCT in pts with advanced TNBC and gBRCAm.  This abstract reports on a post hoc analysis of PROs from the EMBRACA trial. In pts with gBRCAm advanced TNBC, TALA resulted in significantly greater improvement from baseline and delayed TTD (time to deterioration) in GHS/QoL (global health status/quality of life) and pain symptoms vs PCT.
