Number of Participants With Treatment Emergent Adverse EventsPrimary· From first dosing (Day 0) up to last follow-up visit or until the event has resolved to baseline grade or better or the event was assessed stable by the investigator or the patient was lost to follow-up or withdrew consent, up to 24 months
Treatment-emergent adverse events (TEAEs) were collected from first dosing up to last follow-up visit or until the event has resolved to baseline grade or better or the event was assessed stable by the investigator or the patient was lost to follow-up or withdrew consent. The distribution of adverse events was done via the analysis of frequencies for treatment emergent Adverse Event (TEAEs), Serious Adverse Event (TESAEs) and Deaths due to AEs, through the monitoring of relevant clinical and laboratory safety parameters. Only descriptive analysis performed.

PSA progression was defined as:
1. For patients with PSA decline: PSA progression was defined as the date that a \>= 25% increase in PSA and an absolute increase of 2 ng/mL or more from the nadir was documented and confirmed by a second consecutive value obtained 3 or more weeks later. Rises in PSA within the first 12 weeks were ignored (PCWG3 Guidance),
2. For patients without PSA decline: PSA progression was defined as a \>= 25% increase from the baseline value along with an increase in absolute value of 2 ng/mL or more after 12 weeks of treatment.

Investigator's assessed bone metastases using the Prostate Cancer Working Group 3 (PCWG3) criteria; new lesions had to be confirmed on a second scan (2+2 rule). The investigator documented their clinical impression of each PCWG3 assessment as Improved, Stable or Progression. The number of participants with a clinical impression of Improved, Stable or Progression according to PCWG3 using investigators assessments was reported by visit.

Change From Baseline in Expanded Prostate Cancer Index Composite Short Form (EPIC-26)Secondary· Baseline, Month 3, Month 6, Follow-up Month 3
The Expanded Prostate Cancer Index-Composite (EPIC) is a well-established patient-reported outcome (PRO) questionnaire developed to monitor health-related quality of life outcomes among prostate cancer. The 26-item version of EPIC, also known as EPIC Short Form or EPIC-26, contains 26 items and 5 domains: Urinary Incontinence (Items 1-4), Urinary Irritative/Obstructive (Items 5-8), Bowel (Items 10-15), Sexual (Items 16-21), and Hormonal (Items 22-26). Response options for each EPIC item form a Likert scale, and multi-item scale scores are transformed linearly to a 0 to 100 scale for each domai
