Darolutamide+ADT Post-RP w/o ePLND in hrPC: Briganti 2019

Efficacy and Safety Evaluation of Darolutamide+ADT Adjuvant After Radical Prostatectomy (RP) Without ePLND, in High-risk Prostate Cancer Patients Based on Briganti 2019 Nomogram: A Phase II, Single-center, Single-arm, Prospective Study

Rövid összefoglaló (regiszter, angolul)

The goal of this clinical trial is to evaluate whether adjuvant darolutamide plus androgen-deprivation therapy (ADT) can reduce post-operative recurrence and improve disease control in high-risk prostate cancer patients-defined by the Briganti 2019 nomogram-who have undergone radical prostatectomy (RP) without extended pelvic lymph node dissection (ePLND). The main questions it aims to answer are: 1. What proportion of participants remains biochemical-recurrence-free at 2 years, using NCCN criteria (PSA increase \>0.1 ng/mL above post-treatment nadir confirmed by two tests ≥2 weeks apart)? 2. What proportion of participants is the 2-year radiographic progression-free survival (rPFS)? Additional key outcomes include: * PSA undetectable rates at 6, 12, and 24 months (PSA \<0.01 ng/mL). * Safety and tolerability assessed by CTCAE v5.0. * Exploratory\*\* patient-reported outcomes: urinary symptoms (IPSS) and quality of life (EQ-5D-3L). Study type \& design: Phase II, single-center, single-arm, prospective interventional study. Enrollment occurs within 12 weeks after RP. ADT is delivered with a GnRH agonist (physician's choice); orchiectomy is excluded. Target sample size is approximately 40 participants; the statistical plan uses a one-sample log-rank framework. Primary and secondary endpoints are assessed over 2 years. Participants will: Provide informed consent and undergo eligibility confirmation (high-risk per Briganti 2019; post-RP without ePLND; enrollment ≤12 weeks after surgery). Receive darolutamide + ADT according to protocol (GnRH agonist; no orchiectomy). Attend scheduled visits for PSA monitoring, safety labs, and adverse-event assessments (CTCAE v5.0). Undergo radiologic evaluations as per protocol to determine rPFS (RECIST 1.1/PCWG3). Complete IPSS and EQ-5D-3L questionnaires at specified time points to assess urinary symptoms and quality of life. Primary endpoint: 2-year biochemical-recurrence-free rate. Key secondary endpoints: 2-year rPFS; PSA \<0.01 ng/mL at 6/12/24 months; treatment-emergent adverse events. Exploratory endpoints: IPSS and EQ-5D-3L changes over 2 years. This trial aims to balance oncologic control with quality of life in a population for whom the therapeutic value of ePLND remains uncertain, by testing whether early adjuvant darolutamide + ADT after RP can meaningfully delay recurrence and progression while maintaining acceptable tolerability.

    • Systemic therapy, including but not limited to: \>2 months of ADT; \>2 months of conventional hormonal therapy (e.g., flutamide, bicalutamide); next-generation hormonal agents (e.g., darolutamide, abiraterone, apalutamide, enzalutamide, relugolix); chemotherapy (e.g., docetaxel); immunotherapy; targeted therapy;
    • Local radiotherapy;
  • Concurrent participation in, or planned participation in, another clinical trial;
