Clinical Trial Summary

RATIONALE: Neoadjuvant hormonal therapy using luteinizing hormone releasing hormone (LHRH) agonists and/or anti-androgens has already demonstrated to downstage primary prostate cancer in patients treated by radical prostatectomy without a survival benefit. There is no evidence yet of a survival impact of LHRH antagonist (LHRHa) +/- new-generation anti-androgens in this setting. Thus novel studies are needed to assess this treatment combination. PURPOSE: To assess the difference in treatment antitumor effect between arms by measuring pathological tumor volume with minimal residual disease (MRD) following radical prostatectomy + pelvic lymph-node dissection (RP + PLND) for intermediate or high-risk prostate cancer patients.


Clinical Trial Description

PRIMARY OBJECTIVE: To assess the difference in antitumor effect between the treatment arms by measuring MRD following radical prostatectomy. SECONDARY OBJECTIVES: To measure differences between study arms in - Proportions of post neoadjuvant prostate specific antigen (PSA) ≤ 0.3 ng/ml as a predictor of prostate cancer mortality - T down-staging, complete pathological response, PSA kinetics, Testosterone kinetics, operation time, blood loss, grade of surgical difficulty - New generation hybrid imaging 68Ga PSMA (Prostate-Specific Membrane Antigen) PET/MR (Positron emission tomography/Magnetic Resonance) derived parameters - Early biochemical recurrence as prognostic factor of prostate cancer mortality - Transcriptome and genome - Tissue microarrays (TMA) protein expression (DNA repair, resistance etc.) by immunohistochemistry - Perioperative safety and tolerability - Quality of life, erection recovery, continence through validated preoperative and postoperative questionnaires pre and postop (IEEF5, ICIQ, EORTC QLQ-C30) OUTLINE: interventional, single center, phase II, randomized, double blind, placebo controlled trial. ;
