Interventions

  • Olaparib — DRUG
    300 mg orally twice a day (D1-D30) for 6 Cycles (30 day Cycles)
  • LHRH agonist — DRUG
    Total duration of therapy will be for 180 days with use of agent as per institutional standards

Study Details

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.

Arms

  • Experimental: Investigational Group
    300 mg of olaparib taken orally twice a day for 6 cycles (approximately 6 months). There are 30 days in a cycle. Olaparib will be taken with an LHRH agonist (leuprolide, triptorelin, or goserlin). This choice of therapy will be taken for a total of 180 days per institutional standards. After 6 cycles of neoadjuvant therapy, patients will undergo a radical prostatectomy (RP). After RP, patients will be followed for testosterone recovery and PSA progression.
