PATIENT-REPORTED OUTCOMES FOR HRQoL1-6

HRQoL icon

Patients maintained health-related quality of life (HRQoL) while taking ERLEADA® with ADT in both the TITAN and SPARTAN studies1-6

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.

*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

The FACT-P is a 39-item questionnaire developed and validated specifically in patients with prostate cancer.

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

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.
