Trial Outcomes & Findings for Open Label Phase Two Trial of Radium Ra 223 Dichloride With Concurrent Administration of Abiraterone Acetate Plus Prednisone in Symptomatic Castration-Resistant (Hormone-Refractory) Prostate Cancer Subjects With Bone Metastasis (NCT NCT02097303)

NCT ID: NCT02097303

Last Updated: 2018-02-01

Results Overview

Following Quality of Life questionnaires were given at each visit: FACT-P assesses symptoms/problems related to prostate carcinoma and its treatment. It is a combination of the FACT- General + the PCS (Range 1-156, higher scores better). The FACT-General (FACT-G) is a 28 item QOL measure that provides a total score as well as subscale scores: Physical (0-28), Functional (0-28), Social (0-28), Emotional (0-24) Well-being, and Satisfaction with Treatment was not assessed for this study (The total range was between 1-108, higher scores better) FACT-TOI is derived from the sum of the Physical Well-Being, Functional Well-Being, and Prostate Cancer subscale scores; a sensitive measure of patient-reported health (Range 1-104, higher scores better) PCS is a 12-item prostate cancer subscale that asks about symptoms and problems specific to prostate cancer (Range 0-48, higher scores better).

PRIMARY outcome

Timeframe: Subjects were evaluated at the screening visit, monthly during the study, and 30 days after the last dose of Radium Ra 223 dichloride, which will be approximately 32 weeks after the screening visit of evaluable subjects.

Population: Improvement at the EOT visit was defined as increase from baseline of \>= 10 points for FACT-P Total Scale. \>9 points for FACT-G Total and FACT-TOI scales, and \>=3 points for the remaining scales.

PRIMARY outcome

Timeframe: Subjects were evaluated at the screening visit, monthly during the study, and 30 days after the last dose of Radium Ra 223 dichloride, which will be approximately 32 weeks after the screening visit of evaluable subjects.

Improvement in Bone Pain was assessed using the Bone Pain Inventory (BPI) 1. Pain Severity: Pain severity is the composite of scores of worst pain, least pain, average pain, and pain now. CMI criteria: Decrease \>30% at two consecutive visits in Pain Severity Score in 24 hours without an increase in analgesic use. 2. Pain interference: Pain interference is the composite scores on general activity, mood, walking ability, normal work, relationships with others, sleep and enjoyment of life. CMI criteria: Decrease by 1.25 points or more compared with baseline at two consecutive visits. 3. Transient Pain Flare: Based on the work of Atkinson et al, a transient pain flare was assessed by pain at its worst in 24 hours. CMI criteria: \> 2 points on the BPI-SF Worst Pain scale and subsequent reduction after initiation of Ra-223 and during the first 3 cycles.
