Brief Summary

The goal of this study is to evaluate the efficacy and safety of darolutamide combined with docetaxel and ADT compared to docetaxel combined with ADT in treating locally advanced prostate cancer patients scheduled for radical prostatectomy. The participant population includes adult males with locally advanced prostate cancer (cT3b-cT4, N0, M0 or any cT, N1, M0). The main questions it aims to answer are: Does the combination of darolutamide, docetaxel, and ADT improve treatment outcomes compared to docetaxel combined with ADT? What are the safety profiles and adverse effects associated with each treatment group? Researchers will compare the control group (docetaxel combined with ADT) to the experimental group (darolutamide combined with docetaxel and ADT) to see if the experimental treatment is more effective. Participants will: Receive either docetaxel combined with ADT or darolutamide combined with docetaxel and ADT for 4 cycles (16 weeks) as neoadjuvant treatment. Undergo radical prostatectomy after completing the neoadjuvant treatment. Be followed up for 36 months post-surgery to assess treatment efficacy and safety.

Outcome Measures

Primary Outcomes (1)

• 3-year biochemical progression-free survival (bPFS)

  Every 3 months (±14 days) up to 36 months after surgery

Secondary Outcomes (13)

• Pathological Downstaging Rate after Radical Prostatectomy

  On Surgery day

• Incidence of Treatment-Related Adverse Events

  From screening visit to 30 days after the last neoadjuvant dose or start of new anticancer therapy

• Time to Castration-Resistant Prostate Cancer (CRPC) at 3 Years

  every 3 months PSA tests and every 6 months imaging assessments up to 36 months after surgery

• Objective Response Rate (ORR)

  2-4 weeks after completion of neoadjuvant therapy

• 3-year Radiographic Progression-Free Survival (rPFS)

  Every 6 months (±1 month) post-surgery until 36 months post-surgery (months 6, 12, 18, 24, 30, 36)
