The study treatment darolutamide plus androgen deprivation therapy (ADT) is under development as treatment before surgery for men who have high-risk localized prostate cancer. Darolutamide works by blocking the attachment of androgen hormones to androgen receptors in cancer cells, thereby blocking cancer progression and growth. ADT is an established treatment that is used to lower the amount of androgen hormones (e.g.,testosterone) in the body. The main purpose of this study is to learn how the cancer responds to the two different treatment durations (12 weeks or 24 weeks) of darolutamide combined with ADT used before the men undergo surgery to remove the prostate. For this, the researchers will compare the percentage of participants who either achieve complete response to the treatment (where no cancer cells are found) or with condition of minimal residual disease after the treatment (where only a small amount of cancer cells remains). The study participants will be randomly (by chance) assigned to one of two treatment groups. Depending on the group, they will receive darolutamide tablets by mouth plus ADT administered under the skin for either 12 weeks or 24 weeks. No more than 30 days after the end of the treatments, study participants will be performed with surgery to remove the prostate. Each participant will be in the study for approximately 29 to 32 months, including a screening phase of up to 28 days, 12 weeks or 24 weeks of treatment depending on the treatment groups, followed by the surgery no more than 30 days after the treatment, and a follow up phase of up to 2years after the surgery. 2 visits to the study site are planned during the screening phase, followed by 3 to 6 visits (every 28 days) during treatment. The treatment period ends with a visit within 7 days after the last dose of treatment. During the study, the doctors and their study team will: \* take blood and urine samples \* check the participants' health parameters \* do physical examinations \* check if the participants' cancer has grown and/or spread using CT (computed tomography) or MRI (magnetic resonance imaging) and, if needed, bone scan \* take tumor samples \* ask the participants questions about how they are feeling and what adverse events they are having. An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events, irrespective if they think it is related or not to the study treatments. About 30 days after the last dose of treatment, 5 weeks after the surgery and every 12 weeks thereafter, the study doctors and their team will check the participants' health and any changes in cancer. This follow-up period ends 2 years after the surgery.

The proportion of participants achieving pathologic response rate (pRR: pathologic complete response \[pCR\] or minimal residual disease \[MRD\]) Timeframe: Completion of Follow-up 1, 30 days after last dose of study drug pRR is defined as the proportion of participants with either condition of pCR or MRD at week 12 or 24 in corresponding arm. Proportion of participants with pCR is defined as the proportion of participants with no residual tumor detected in radical prostatectomy (RP) specimens following 12 or 24 weeks of neoadjuvant treatment of darolutamide and ADT per randomization. Proportion of participants with MRD is defined as the proportion of participants that have residual cancer burden (RCB) ≤0.25 cm\\^3 in the RP specimens. ### Secondary outcomes 1. Proportion of participants with pathologic complete response (pCR) Timeframe: Completion of Follow-up 1, 30 days after last dose of study drug Proportion of participants with pCR is defined as the proportion of participants with no residual tumor detected in radical prostatectomy (RP) specimens following 12 or 24 weeks of neoadjuvant treatment of darolutamide and ADT per randomization. 2. Percentage of participants with tumor downstaging (e.g. clinical T3 to pathologic T2) Timeframe: At baseline and immediately after radical prostatectomy The pathology review will compare the T stage of tumor tissue at baseline (Screening) with the T stage of radical prostatectomy (RP) specimen at RP and calculate the proportion of participants whose tumor stage has decreased from the baseline T stage. 3. Percentage of participants with positive surgical margin (PSM) Timeframe: Immediately after radical prostatectomy PSM is defined as the presence of cancer cells at the edge of the tissue removed during surgery. 4. Biochemical complete response (CR) rate prior to radical prostatectomy (RP) and at landmark timepoints post-RP Timeframe: At pre-RP, at 5 weeks, 12 weeks post-RP, and every 3 months after that until Year 2 after RP or end of follow up Biochemical CR rate is defined as participants who attain serum prostate-specific antigen (PSA) level below 0.1 ng/mL (PSA \\<0.1 ng/mL). 5. Biochemical recurrent free survival since radical prostatectomy (RP) among participants with prostate-specific antigen (PSA) <0.1 ng/mL after RP Timeframe: From RP to biochemical recurrence or death whichever occurs first, up to 2.5 years Biochemical recurrent free survival is defined as time from RP to biochemical recurrence or death, whichever occurs first. The endpoint will be assessed only among participants with PSA \\<0.1 ng/mL after RP. Biochemical recurrence is defined as PSA ≥0.1 ng/mL in 2 consecutive measurements after RP. The date of the first measurement defines the date of biochemical recurrence. 6. Incidence and severity of treatment-emergent adverse events (TEAEs) (including treatment-emergent serious adverse events \[TESAEs\]) Timeframe: From first dose of study drug up to 30 days after the end of study drug administration TEAEs are defined as AEs with an onset date on or after the first dose of study drug and up to the end-of-study drug plus 30 days or with an onset date prior to the first dose of study drug but worsening in intensity after the study drug. Events with missing onset dates will be included as treatment-emergent.
