Patient-reported outcomes
No differences were observed in overall mean change from baseline with 1st line IBRANCE® + letrozole vs placebo + letrozole in FACT-B total and FACT-G total scores in PALOMA-2 (PROs; secondary endpoint)*2

- In a post-hoc analysis, IBRANCE® + letrozole demonstrated a greater improvement in pain scores vs placebo + letrozole: 0.256 vs -0.098; p=0.0183*2
*FACT-B is a 37-item self-reporting instrument containing the 27-question FACT-G survey and a 10-question breast cancer additional concerns scale. A higher score in any FACT-B assessment indicates better QoL. A higher raw score on the pain item indicates higher pain severity. Between-treatment comparisons were non-statistically significantly different for all scales and domains.2
CI = confidence interval; FACT-B = Functional Assessment of Cancer Therapy – Breast; FACT-G = Functional Assessment of Cancer Therapy – General; LET = letrozole; NS = not significant; PLA = placebo; PRO = patient-reported outcomes; QoL = quality of life; TOI = Trial Outcome Index.
In an updated non-prespecified subgroup analysis, no differences were observed in overall mean change from baseline with 1st line IBRANCE® + letrozole vs placebo + letrozole in FACT-B total score across all subgroups studied in PALOMA-2 (PROs; secondary endpoint)*3

QoL scores, including physical, social and emotional functioning, were maintained from baseline with IBRANCE® + fulvestrant and placebo + fulvestrant in 1st line or later in PALOMA-3 (PROs; secondary endpoint)2
- Statistically significant difference in global QoL and emotional functioning from baseline vs placebo + fulvestrant*2
Mean overall change from baseline on EORTC QLQ-C30 *2

Data cut-off December 5, 2014 used for interim analysis; median follow-up 5.6 months.
- In a post-hoc analysis, IBRANCE® + fulvestrant demonstrated a greater delay in QoL deterioration vs placebo + fulvestrant (HR=0.641; p=0.0065)†2
*Mean overall change from baseline on the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Core Module (QLQ-C30). Higher scores (range 0–100) indicated better functioning/QoL or higher symptom severity. The changes from baseline that were statistically significantly different between treatment groups were for Global QoL and emotional functioning.2 †Time to deterioration was defined as a decrease of ≥10 points from baseline, with no subsequent increase above this threshold.2

Significant delay in time to deterioration in pain symptoms with IBRANCE® + fulvestrant in 1st line or later vs placebo + fulvestrant in PALOMA-3 (PROs; secondary endpoint)2
Median time to deterioration (mTTD) in pain symptoms*2

Data cut-off date: March 16, 2015.3
- In a post-hoc analysis, IBRANCE® + fulvestrant demonstrated a greater decrease in pain symptom scores vs placebo + fulvestrant (-3.3 vs 2.0; p=0.0011)†2
- In a post-hoc analysis, decreases in pain symptom scores in patients with visceral disease were consistent with those observed in the primary PRO analysis‡2
*TTD defined as time to ≥10-point increase from baseline. 131 (39.1%) patients in the IBRANCE® + fulvestrant group had an event vs 83 (50%) in the placebo + fulvestrant group.2 †Mean overall change from baseline on the EORTC QLQ-C30. Higher scores (range 0–100) indicated better functioning/QoL or higher symptom severity.2 ‡Visceral metastasis was defined as lung, liver, brain, pleural, or peritoneal involvement. 59% of patients in PALOMA-3 who received IBRANCE® + fulvestrant presented with visceral metastasis (n=206).3 Consistent results shown in a sub-group of 199 patients.2
