Clinical Trial Summary

Primary Objective: To compare the radiographic progression-free survival (rPFS) (using Response Evaluation Criteria in Solid Tumors [RECIST] 1.1 for tumor lesions and Prostate Cancer Working Group 2 (PCWG2) criteria for bone scan lesions or death due to any cause) with chemotherapy (cabazitaxel plus prednisone, Arm A) versus Androgen Receptor (AR)-targeted therapy (enzalutamide or abiraterone acetate plus prednisone, Arm B) in mCRPC participants who have been treated with docetaxel and who had disease progression while receiving AR-targeted therapy within 12 months of AR treatment initiation (less than or equal to [<=]12 months, either before or after docetaxel). Secondary Objective: - To compare efficacy for: - Prostate-specific antigen (PSA) response rate and time to PSA progression (TTPP). - Progression-free survival (PFS). - Overall survival (OS). - Tumor response rate and duration of tumor response. - Pain response and time to pain progression. - Symptomatic skeletal event (SSE) rate and time to occurrence of any SSE. - Health status and Health-related Quality of Life (HRQOL). - To evaluate the correlation of a signature of resistance to AR-targeted agents with clinical outcome via the analysis of circulating tumor cell (CTC) phenotypes as well as expression and localization of proteins including AR isoforms in CTCs. - To evaluate safety in the 2 treatment arms.

Description:

The duration of the study per participant was approximately 2 years. Each participant was treated until radiographic disease progression, unacceptable toxicity, or participant's refusal of further study treatment, and each participant was followed after completion of study treatment until death, study cut-off date, or withdrawal of participant consent.

Analysis performed by Kaplan-Meier method.	From time from randomization until PSA progression, death due to any cause or data cut-off whichever comes first (maximum duration: up to 141 weeks)
Secondary	Duration of Tumor Response	Duration of tumor response was defined as the time (in months) from date of first response (CR or PR) until date of first documentation of tumor progression or death, whichever occurs first. As per RECIST 1.1 CR was defined as disappearance of all target and non-target lesions and normalization of tumor marker level. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. PR was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. Progression was defined as at least a 20% increase in sum of diameters of target lesions, unequivocal progression of existing non-target lesions. Analysis was performed by Kaplan-Meier method.	From the date of the first response to the date of first documented tumor progression, or death due to any cause or data cut-off date whichever comes first (maximum duration: up to 141 weeks)
Secondary	Percentage of Participants Achieving Pain Response Assessed Using Brief Pain Inventory-Short Form (BPI-SF) Pain Intensity Score	Pain response as per BPI-SF was defined as a decrease of at least 30% from Baseline in the average of BPI-SF pain intensity score observed at 2 consecutive evaluations >=3 weeks apart without increase in analgesic usage score (calculated from analgesic use data, with non-narcotic medications assigned value of 1 point and narcotic medications assigned 4 points). The BPI-SF is a self-administered questionnaire developed to assess the severity of pain on a 0-10 categorical scale where 0=no pain, 10=pain as bad as you can imagine. Higher scores indicated worst outcomes. Percentage of Participants Achieving Pain Response assessed using BPI-SF Pain Intensity Score were reported.	Baseline until pain progression, first further anticancer therapy, or data cut-off whichever comes first (maximum duration: up to 141 weeks)
Secondary	Time to Pain Progression	Time to pain progression was defined as the time duration (in months) between the date of randomization and the date of first documented pain progression. Pain progression, in participants with no pain or stable pain at Baseline was defined as increase of >=30% from baseline in the BPI-SF pain intensity score observed at 2 consecutive evaluations >=3 weeks apart without decrease in analgesic usage score or increase in analgesic usage score (calculated from analgesic use data, with non-narcotic medications assigned value of 1 point and narcotic medications assigned 4 points) >=30%. The BPI-SF is a self-administered questionnaire developed to assess the severity of pain on a 0-10 categorical scale where 0=no pain, 10=pain as bad as you can imagine. Higher scores indicated worst outcomes. Analysis was performed by Kaplan-Meier method.	Baseline until pain progression or data cut-off whichever comes first (maximum duration: up to 141 weeks)
Secondary	Number of Symptomatic Skeletal Events (SSE)	SSE was defined as occurrence of a new symptomatic pathological fracture, use of external beam radiation to relieve bone pain, occurrence of spinal cord compression or tumor- related orthopedic surgical intervention.	Baseline until occurrence of first SSE or data cut-off, whichever comes first (maximum duration: up to 141 weeks)

Secondary	Health-Related Quality of Life (HRQOL): Change From Baseline in Functional Assessment of Cancer Therapy-Prostate (FACT-P) Total Score at Cycle 2, 3, 4, 5, 6, 7, 8 and End of Treatment	Health-related quality of life (HRQOL) evaluation was performed using the FACT-P questionnaire (Version 4). FACT-P was a 39-item participant rated questionnaire that measures the concerns of participants with prostate cancer. It consisted of 5 sub-scales assessing physical well-being (7 items), social/family well-being (7 items), emotional well-being (6 items), functional well-being (7 items), and prostate-specific concerns (12 items). FACT-P total score was the sum of all 5 subscale scores. It ranged from 0 to156 with higher score indicated better quality of life with fewer symptoms. Baseline corresponded to last evaluable assessment before treatment administration.	Baseline, Day 1 of each Cycle 2, Cycle 3, Cycle 4, Cycle 5, Cycle 6, Cycle 7, Cycle 8 and at End of Treatment (any time up to 141 weeks)
Secondary	Change From Baseline in European Quality of Life Working Group Health Status Measure 5 Dimensions, 5 Levels (EQ-5D-5L) Utility Single Index and Visual Analogue Scale (VAS) Scores at Cycle 2, 3, 4, 5, 6, 7, 8 and End of Treatment	EQ-5D was a standardized HRQOL questionnaire consisting of EQ-5D descriptive system and Visual Analogue Scale (VAS). EQ-5D descriptive system comprised of 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression measured on 3 levels (no problem, some problems & severe problems) within a particular EQ-5D dimension. 5 dimensional 3-level system was converted into single index utility score. Possible values for single index utility score ranged from -0.594 (severe problems in all dimensions) to 1.0 (no problem in all dimensions) on scale where 1 represented best possible health state. EQ-5D VAS was used to record a participant's rating for his/her current health-related quality of life state and captured on a vertical VAS scale ranging from 0-100, where 0=worst imaginable health state and 100=best imaginable health state, where higher states indicated better outcomes. Baseline corresponded to last evaluable assessment before treatment administration.	Baseline, Day 1 of each Cycle 2, Cycle 3, Cycle 4, Cycle 5, Cycle 6, Cycle 7, Cycle 8 and at End of Treatment (any time up to: 141 weeks)
Secondary	Radiographic Progression-Free Survival (rPFS) in Participants With Presence and Absence of Biomarker	Circulating tumor cell (CTC) counts were considered as biomarker in a liquid biopsy. rPFS in participants with presence and absence of subtypes of CTC biomarker i.e. chromosomal instability (CIN) and neuroendocrine (NE) was reported in this outcome measure. rPFS was defined as: time (in months) from randomization to the first occurrence of any one of following: radiological tumor progressions (RECIST1.1), progression of bone lesions (PCWG2 criteria) or death due to any cause. Progression (RECIST1.1): at least a 20% increase in sum of diameters of target lesions, unequivocal progression of existing non-target lesions. Progression of bone lesions (PCWG2 criteria): first bone scan with >= 2 new lesions compared to Baseline observed <12 weeks from randomization and confirmed by a second bone scan performed >=6 weeks later; first bone scan with >=2 new lesions compared to Baseline observed >=12 weeks from randomization and new lesions were verified on next bone scan >= 6 weeks later.	From randomization until tumor progression or bone lesion progression, death due to any cause, or data cut-off date whichever comes first (maximum duration: up to 141 weeks)
