PATIENT-REPORTED OUTCOMES FOR HRQoL1-6
HRQoL based on patient-reported outcomes is not reported in the ERLEADA® Prescribing Information. HRQoL should be viewed in the context of patient management and the overall physical condition and clinical course of the patient.
In the TITAN study
Pre-specified exploratory endpoint
HRQoL WAS MAINTAINED WITH ERLEADA® + ADT AFTER A MEDIAN FOLLOW-UP OF 44.0 MONTHS
Analysis of change from baseline in the FACT-P total score showed no substantial between-group differences.1*
Mean Change From Baseline in FACT-P Total Score
*The FACT-P patient-reported outcome questionnaire was used to assess prostate cancer symptoms, pain-related symptoms, and overall HRQoL in the TITAN study. The FACT-P is a 39-item questionnaire developed and validated specifically in patients with prostate cancer. The scores for 5 FACT-P subscales (physical well-being, social and family well-being, emotional well-being, functional well-being, and prostate cancer subscale) can be added together to make a single overall score that ranges from 0-156. Higher values of FACT-P total and all subscales indicate a higher HRQoL. In the TITAN study, the FACT-P was completed during Cycles 1 to 7, then every other cycle until the end of treatment, and at months 4, 8, and 12 in follow-up. Each treatment cycle was 28 days.2,3

HRQoL based on patient-reported outcomes is not reported in the ERLEADA® Prescribing Information. HRQoL should be viewed in the context of patient management and the overall physical condition and clinical course of the patient.
In the SPARTAN study
Pre-specified exploratory endpoint
HRQoL WAS MAINTAINED WITH ERLEADA® + ADT AFTER A MEDIAN FOLLOW-UP OF 52.0 MONTHS.
IN PATIENTS RECEIVING ADT ALONE, HRQoL DECLINED AFTER APPROXIMATELY 1 YEAR5*
*The FACT-P patient-reported outcome questionnaire was used to assess prostate cancer symptoms, pain-related symptoms, and overall HRQoL in the SPARTAN study. The FACT-P is a 39-item questionnaire developed and validated specifically in patients with prostate cancer. The scores for 5 FACT-P subscales (physical well-being, social and family well-being, emotional well-being, functional well-being, and prostate cancer subscale) can be added together to make a single overall score that ranges from 0-156. Higher values of FACT-P total and all subscales indicate a higher HRQoL. The FACT-P was given and collected during the treatment phase at baseline, on Day 1 of Cycle 1 (before dose), Day 1 of Cycles 2-6, Day 1 of every 2 cycles starting at Cycle 7 to Cycle 13, and then Day 1 of every 4 cycles, unless otherwise specified. Each treatment cycle was 28 days.6
Post hoc analysis
ENERGY LEVELS WERE MAINTAINED WHILE TAKING ERLEADA® + ADT6†
Analysis of answers to the question from the FACT-P physical well-being domain,
“I have a lack of energy”6‡
†The Functional Assessment of Cancer Therapy-Prostate (FACT-P) patient-reported outcome questionnaire was used to assess prostate cancer symptoms, pain-related symptoms, and overall HRQoL. Patient-reported outcome data are shown for 29 cycles, approximately 25.8 months from the start of treatment; data from subsequent treatment cycles were not interpretable because fewer than 20 patients remained in the placebo group. Generally, the total and subscale scores for FACT-P were maintained with ERLEADA® from baseline until treatment Cycle 29. There were similar data showing this preservation of HRQoL from baseline EQ-5D-3L. Maintenance of HRQoL was also observed with placebo.5 Patients were required to complete the two paper, self-administered patient-reported outcome questionnaires before any other interventions or examinations on the day of the clinic visit. FACT-P and EQ-5D-3L were given and collected during the treatment phase at baseline, on Day 1 of Cycle 1 (before dose), Day 1 of Cycles 2–6, Day 1 of every two cycles starting at Cycle 7 to Cycle 13, then Day 1 of every four cycles, unless otherwise specified. This frequency enabled assessment of treatment tolerability and patients’ HRQoL over time.6
‡The results were consistent across all FACT-P subscales.
Consistent efficacy demonstrated in 2 pivotal trials
ADT = androgen deprivation therapy; FACT-P = Functional Assessment of Cancer Therapy-Prostate; HRQoL = health-related quality of life; mCSPC = metastatic castration-sensitive prostate cancer; NE = not estimable; nmCRPC = non-metastatic castration-resistant prostate cancer; SPARTAN = Selective Prostate Androgen Receptor Targeting with ARN-509; TITAN = Targeted Investigational Treatment Analysis of Novel Anti-androgen.
