Change From Baseline in Quality of Life as Assessed by Functional Assessment of Cancer Therapy-Prostate (FACT-P) Functional Well-Being Domain Scores

Safety Study of Continued Enzalutamide Treatment In Prostate Cancer Patients · Source last updated 2023-09-18

Results reported by the registry submitting party. Population, time horizon, units and missing values must be read together.

Measure: MEAN
Unit: units on a scale
Interval / dispersion: Standard Deviation
Time frame: Baseline, Week 9, 13, 17, 21, 25, 29, 33, 37, 41, 45, 49, 53, 57, 61, 65, 69, 73, 77, 81, 85, 89

What was measured

The FACT-P is a multidimensional, self-reported quality of life instrument consisting of 27 core items that assess participant function in 4 domains: physical, social/family, emotional, functional well-being, and supplemented by 12 site-specific items to assess for prostate-related symptoms. Each item is rated on a 0 to 4 Likert-type scale, and then combined to produce subscale scores for each domain. Total subscale score range for functional well-being domain is from 0 (worst response) to 28 (best response), where higher score indicate better quality of life.

Analysis population: ITT population included all participants randomly assigned to study treatment.

Groups in this outcome

Enzalutamide 160mg+Abiraterone 1000mg+ Prednisone 10mg

Participants with confirmed PSA progression at Week 21 in open label period, received enzalutamide 160 mg as four 40 mg capsules, orally once daily along with abiraterone 1000 mg as four 250-mg tablets, orally once daily and prednisone 5 mg tablet, orally twice daily in double blind treatment period, up to disease progression (as defined by radiographic imaging or unequivocal clinical progression or death on study), intolerable toxicity, or participant withdrawal, whichever occurred first. Participants were followed up for 16 weeks at 4-week interval after discontinuation of study drug for survival and subsequent antineoplastic therapy for prostate cancer.

Placebo+Abiraterone 1000mg+ Prednisone 10mg

Participants with confirmed PSA progression at Week 21 in open label period, received placebo matched to enzalutamide as four 40 mg capsules, orally once daily along with abiraterone 1000 mg as four 250-mg tablets, orally once daily and prednisone 5 mg tablet, orally twice daily in double blind treatment period, up to disease progression (as defined by radiographic imaging or unequivocal clinical progression or death on study), intolerable toxicity, or participant withdrawal, whichever occurred first. Participants were followed up for 16 weeks at 4-week interval after discontinuation of study drug for survival and subsequent antineoplastic therapy for prostate cancer.
