- Metastasis-free survival (MFS) [ Time Frame: From randomization to development of metastatic disease or death, whichever occurs first, assessed up to 36 months ]The primary comparison will be an intention-to-treat analysis of all randomized patients. The method of Kaplan and Meier will be used to characterize the time-to-event endpoints, and a logrank test will be used to compare these endpoints across treatments.
- Recurrence-free survival (RFS) [ Time Frame: From randomization to any of the MFS events, pelvic lymph node recurrence or detectable prostate-specific antigen (PSA) (PSA >= 0.2 ng/mL, confirmed by a second PSA of the same level or higher), whichever occurs first, assessed up to 36 months ]The method of Kaplan and Meier will be used to characterize the time-to-event endpoints, and a logrank test will be used to compare these endpoints across treatments.
- Event-free survival [ Time Frame: From randomization to any of the RFS events, treatment with salvage radiation therapy with or without systemic therapy, or initiation of systemic therapy for presumed recurrence, whichever occurs first, assessed up to 36 months ]The method of Kaplan and Meier will be used to characterize the time-to-event endpoints, and a logrank test will be used to compare these endpoints across treatments.
- Overall survival [ Time Frame: From randomization to death by any cause or date last known alive, assessed up to 36 months ]The method of Kaplan and Meier will be used to characterize the time-to-event endpoints, and a logrank test will be used to compare these endpoints across treatments.
- Testosterone recovery rate [ Time Frame: At time of disease progression, assessed up to 36 months ]Exact binomial confidence intervals will be used to describe the proportions of patients with testosterone recovery in each arm.
- Time to testosterone recovery [ Time Frame: From randomization to a return of serum testosterone level to greater than or equal to lower limit of normal for the testosterone assay, assessed up to 36 months ]The method of Kaplan and Meier will be used to characterize the time-to-event endpoints, and a logrank test will be used to compare these endpoints across treatments.
- Incidence of adverse events [ Time Frame: Up to 78 weeks ]Toxicity will be defined using the Common Terminology Criteria for Adverse Events version 5.0.
- Change in quality of life: Functional Assessment of Cancer Therapy (FACT) [ Time Frame: Baseline up to 18 months ]Will be assessed by the Functional Assessment of Cancer Therapy (FACT) - Prostate, FACT - Cognitive, and Functional Assessment of Chronic Illness Therapy - Fatigue. Fatigue instruments at baseline, 6, 12 and 18 months, and descriptive statistics will be used to characterize quality of life over time in each arm. Each item is answered on a 5-point Likert-type scale, where a value of 0 indicates the statement is not applicable, and a value of 5 indicates the statement is applicable to the respondent. Subgroup analysis will be performed among patients who receive adjuvant radiation therapy and patients who do not receive adjuvant radiation therapy in each arm. Mixed effect models will be constructed as an exploratory analysis to estimate the time profile of quality of life assessments in the two arms and to evaluate treatment-by-time interactions.
- Overall quality of life: Functional Assessment of Cancer Therapy (FACT) [ Time Frame: At 18 months ]Will be assessed by the Functional Assessment of Cancer Therapy (FACT) - Prostate total score. The total score can range from 0 to 156, where a higher value indicates a better quality of life. Mixed effect models will be constructed as an exploratory analysis to estimate the time profile of quality of life assessments in the two arms and to evaluate treatment-by-time interactions.
- Change in Functional Assessment of Cancer Therapy (FACT) - Prostate score [ Time Frame: Baseline up to 18 months ]A paired t test will be used to compare Functional Assessment of Cancer Therapy (FACT) - Prostate scores at these two time points in each arm. The total score can range from 0 to 156, where a higher value indicates a better quality of life. A two-sample t test will be performed to compare the changes in FACT - Prostate scores from baseline to 18 months between the two arms. Mixed effect models will be constructed as an exploratory analysis to estimate the time profile of quality of life assessments in the two arms and to evaluate treatment-by-time interactions.
- Cognitive function [ Time Frame: At 12 months (completion of treatment) ]Will be measured between the two arms by Functional Assessment of Cancer Therapy (FACT) - Cognitive. The FACT-Cognitive has four subscales: perceived cognitive impairments (PCI), perceived cognitive abilities, impact of perceived cognitive impairment on quality of life, and comments from others on cognitive function. Summary statistics will be used to describe each subscale at each time point and the PCI subscale score, which ranges from 0-72, where higher values indicate better quality of life, at 12 months will be the primary measurement of this analysis. Bonferroni correction will be employed for the 3 follow-up time points of interest (6, 12, and 18 months) to make the analysis conservative. Mixed effect models will be constructed as an exploratory analysis to estimate the time profile of quality of lifeassessments in the two arms and to evaluate treatment-by-time interactions.
- Change in cognitive function [ Time Frame: Baseline up to 12 months (completion of treatment) ]Will be measured between the two arms by Functional Assessment of Cancer Therapy (FACT) - Cognitive.

Summary statistics will be used to describe each subscale at each time point and the PCI subscale score, which ranges from 0-72, where higher values indicate better quality of life, at 12 months will be the primary measurement of this analysis. Bonferroni correction will be employed for the 3 follow-up time points of interest (6, 12, and 18 months) to make the analysis conservative. Mixed effect models will be constructed as an exploratory analysis to estimate the time profile of quality of life assessments in the two arms and to evaluate treatment-by-time interactions.
- Identification of novel gene expression signatures [ Time Frame: Up to 36 months ]The associations between the gene expression signatures and clinical outcomes will be assessed by Cox proportional hazards models and logrank test.
- Prognostic value of established signatures [ Time Frame: Up to 36 months ]Will include androgen receptor activity, basal-luminal subtyping by modified PAM50 and androgen deprivation therapy score using Cox proportional hazards models. Similar analysis will be performed to evaluate the prognostic value of luminal-basal subtype. The treatment-by-subtype interaction will also be assessed. For androgen deprivation therapy score, patients will be categorized into either low or high androgen deprivation therapy score using a cutoff of 0.36.
- Decipher scores [ Time Frame: Up to 36 months ]Will be associated with MFS as well as disease characteristics. Cox proportional hazards models will be performed with adjustment for important disease characteristics, including prostate-specific antigen, Gleason score, disease stage, pathology of the radical prostatectomy specimen, etc. Decipher score could be categorized into a few risk groups and the Akaike information criterion method will be used to determine the optimal number of cutoff points. To assess whether treatment effect is affected by Decipher score levels, the treatment-by-Decipher interactions will be included in the model as well. Decipher scores range from 0.00 to 1.00, where higher values indicate higher risk disease.
- Genome-wide alterations [ Time Frame: Up to 36 months ]Prostate cancer specimens will be banked for future studies to perform genome-wide alterations in coding and non-coding deoxyribonucleic acid sequences. To identify the genetic alterations that are associated with development of metastasis, Cox proportional hazards models and logrank test will be used. The analysis will focus on actionable alterations first. The treatment-by-alteration interactions will also be assessed to determine whether response to darolutamide is affected by distinct genomic subgroups. Ultimately the findings on gene expression signatures and deoxyribonucleic acid alterations will be assessed in the models simultaneously to identify subsets of patients who might benefit most from the treatment of ADT with or without darolutamide.
