Percentage of Participants With Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs) |
An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment emergent are events between first dose of study drug and up to 30 days after last dose of study drug that were absent before treatment, or worsened during the treatment period relative to the pretreatment state. AEs included both serious and non-serious. |
Baseline up to 30 days after the last dose of study drug or before initiation of a new antitumor treatment, whichever occurred first (maximum of 99.4 months) |

Percentage of Participants With Adverse Events (AEs) Leading to Study Drug Discontinuation |
An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Outcome of an AE was response to a question answered by the investigator: 'Is the AE leading to study discontinuation or death?' as 'yes'. |
Baseline up to 30 days after the last dose of study drug or before initiation of a new antitumor treatment, whichever occurred first (maximum of 99.4 months) |

Percentage of Participants With Treatment-Emergent Treatment-Related Adverse Events (AEs) and Serious Adverse Events (SAEs) |
Treatment-related AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent were events between first dose of study drug and up to 30 days after last dose of study drug that were absent before treatment or that worsened relative to pre-treatment state. Relatedness to study drug was assessed by the investigator. |
Baseline up to 30 days after the last dose of study drug or before initiation of a new antitumor treatment, whichever occurred first (maximum of 99.4 months) |

Primary |
Progression Free Survival (PFS) |
PFS = time from randomization to first documentation of radiographic progression (RP),unequivocal clinical progression or death due to any cause (death within 112 days of treatment discontinuation without objective evidence of RP),whichever occurred first as per investigator. Unequivocal disease progression was pain requiring chronic administration of analgesics, decline of prostate cancer of Eastern Cooperative Oncology Group (ECOG) performance status score to 3 or higher or initiation of new anticancer therapy/radiation therapy or surgical intervention due to tumor progression. ECOG score range= 0(no severity) to 5(maximum severity).RP for bone disease was evaluated by appearance of 2 or more new bone lesions as per Prostate Cancer Clinical Trials Working Group 2 (PCWG2) or for soft tissue disease according to Response Evaluation Criteria in Solid Tumor version 1.1. Participants with no PFS event at analysis date were censored at last tumor assessment date prior to data cutoff date. |
From randomization until disease progression, last tumor assessment without disease progression or death due to any cause, whichever occurred first (maximum up to 20.3 months) |
|
Secondary |
Time to Prostate Specific Antigen (PSA) Progression |
Time from date of randomization to the date of first confirmed PSA progression as per Prostate Cancer Clinical Trials Working Group 2 (PCWG2). For participant's whose PSA decreased at Week 13 after randomization, progression was defined as 25 percent (%) PSA increase relative to nadir or absolute increase of >=2 nanogram/milliliter (ng/mL) above nadir. Progression was confirmed if another assessment measured at least 3 weeks later met the criterion as well. For participant's whose PSA did not decrease at Week 13 after randomization, progression was defined as 25% PSA increase relative to baseline assessed 12 weeks after baseline. Participants who were not known to have had a PFS event at the analysis date were censored at last PSA assessment date prior to data cutoff date. |
From randomization until disease progression, last tumor assessment without disease progression, whichever occurred first (maximum up to 11.1 months) |
|
Secondary |
Prostate Specific Antigen (PSA) Response Rate |
PSA response rate was defined as percentage of participants with >=30% and >=50% decrease in PSA from baseline at randomization to the maximal PSA response with a threshold of 30% and 50% respectively. PSA response was confirmed if another assessment measured at least 3 weeks later met the criterion as well. |
From randomization until disease progression, last tumor assessment without disease progression, whichever occurred first (maximum up to 11.1 months) |
|
Secondary |
Objective Response Rate (ORR) |
Objective response rate as assessed by the investigator according to Response Evaluation Criteria in Solid Tumor version 1.1 (RECIST v1.1) was defined as 1) Percentage of participants with confirmed best overall complete response (CR) and partial response (PR); 2) Percentage of participants with CR, PR and stable disease (SD) for target lesions or non-progressive disease for non-target lesions. CR: Disappearance of all non-nodal target and non-target lesions, including target and non-target lymph nodes reduction to <10 millimeter (mm) in short axis. No new lesions and disappearance of all non-target lesions. PR: >= 30% decrease in sum of diameters of target lesions, compared to the sum at baseline. The short axis was used in the sum for target nodes, while the longest diameter was used in the sum for all other target lesions. |
From randomization until CR or PR, whichever occurred first (maximum up to 21.3 months) |

Rate of Pain Progression |
Rate of pain progression was defined as percentage of participants with an increase of >=30% from baseline in the mean Brief Pain Inventory-Short Form (BPI-SF) pain intensity item scores of 4 items assessing average, worst, least, and intermediate pain severity. BPI-SF is an 11-item self-report questionnaire that is designed to assess the severity and impact of pain on daily functions of a participant. BPI-sf includes 4 questions that assess pain intensity (worst, least, average, right now) and 7 questions that assess impact of pain on daily functions (general activity, mood, walking ability, normal work, relations with other people, sleep, enjoyment of life). BPI-sf score range for each item was from 0=no pain to 10=worst possible pain. Total score was reported as average of individual questions ranges from 0 to 10, where lower scores indicated less pain or less pain interference. |

Time to First Use of New Antineoplastic Therapy for Prostate Cancer |
It was defined as time from randomization to the date of first use of subsequent antineoplastic therapy for prostate cancer. For participants who had not started subsequent antineoplastic therapy as of data analysis cutoff date, the time to first use of subsequent antineoplastic therapy was censored at the date of last assessment. |
From randomization until date of first use of any antineoplastic therapy (after last dose date of Period 2, maximum up to 22.3 months |

Change From Baseline in Quality of Life as Assessed by Functional Assessment of Cancer Therapy-Prostate (FACT-P) Global Score |
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, as well as a global quality of life score which is the sum of all 5 domain scores and ranges from 0 to 156 where higher scores represent better quality of life. |
