Study of Neoadjuvant PARP Inhibition Followed by Radical Prostatectomy in Patients With Unfavorable Intermediate-Risk or High-Risk Prostate Cancer With Select HRR Gene Alterations
NCT05498272 · Status: RECRUITING · Phase: PHASE2 · Type: INTERVENTIONAL · Enrollment: 32
Last updated 2026-01-23
Summary
Phase 2 open-label, single-arm clinical trial evaluating the efficacy and safety of neoadjuvant olaparib + LHRH agonist administered for 6 months prior to radical prostatectomy (RP) in men with unfavorable intermediate-risk or high-risk localized prostate cancer. All patients must have confirmed germline or somatic select HRR alterations. Germline and somatic mutation testing will be performed as part of commercially available CLIA assays and will be validated on a uniform platform centrally all patients retrospectively.
Eligible patients will receive treatment with olaparib + LHRH agonist. Following 6 months of therapy, patients will undergo RP with mandatory lymph node dissection. The lymph node dissection template will be at the discretion of the treating urologist. RP specimens will undergo pathology blinded independent central review. Following RP, patients will be followed for testosterone recovery and PSA progression.
