In pre-clinical models, inhibition of clusterin expression using the second generation antisense OGX-011 can enhance cell death following treatment with androgen ablation, radiotherapy, and chemotherapy. In phase I clinical trials, OGX-011 has been well tolerated and a biologically effective dose has been identified in humans.\n\nStudy Design\n\nThis is an open-label, non-blinded, phase II clinical, tissue pharmacokinetic and pharmacodynamic study of weekly OGX-011 and neoadjuvant hormone therapy prior to radical prostatectomy in patients with localized prostate carcinoma and high-risk features.\n\nStudy Objectives\n\nPrimary Objectives\n\n* To assess the effects of combined neoadjuvant hormone therapy (NHT) and OGX-011 prior to radical prostatectomy on pathologic complete response rates in men with high risk localized prostate cancer.\n\nSecondary Objectives\n\n* To quantify changes in clusterin expression in residual prostate cancer after treatment with NHT and OGX-011.\n* To measure levels of full length OGX-011 in prostate tissues after 3 months of NHT.\n* To assess the safety and tolerability toxicity of 3 months of OGX-011 and NHT prior to radical prostatectomy.\n* To measure evidence of OGX-011's effect on clusterin expression in patient peripheral blood mononuclear cells (PBMNC).\n* To measure evidence of OGX-011's effect on patient clusterin serum levels.\n* To assess the effects of combined NHT and OGX-011 on time to PSA nadir.\n* To determine PSA recurrence rates after combined NHT and OGX-011.\n\nKey Eligibility Criteria\n\n1. Histologically confirmed adenocarcinoma of the prostate, previously untreated\n2. Potential candidate for radical prostatectomy\n3. Any one of the following criteria (minimum of 2 positive biopsies):\n\n * Clinical stage T3\n * Serum PSA \\> 10 ng/ml\n * Gleason score 7-10\n * Gleason score 6 and \\> 3 positive biopsies\n4. ECOG performance status 0-1\n5. WBC ≥ 3.0 x 10\\^9/L\n6. Hemoglobin ≥ 100 g/L\n7. Platelets ≥ 100 x 10\\^9/L\n8. PTT, INR, AST, ALT, creatinine, total bilirubin within normal limits\n\nTreatment Plan\n\nApproximately 45 newly diagnosed, previously untreated patients with clinically localized, high-risk prostate carcinoma will be entered into this trial. These patients will receive neoadjuvant hormone therapy (buserelin 9.9 mg subcutaneously x 1 injection with flutamide 250 mg orally T.I.D. for the first 4 weeks only) for 12 weeks in combination with OGX-011 (a 2'MOE phosphorothioate clusterin antisense oligonucleotide) weekly on a 4 week cycle for 3 courses. For week one, cycle one only, OGX-011 will be given on Days 1, 3 and 5. OGX-011 is given at a dose of 640 mg by intravenous infusion over 2 hours. Radical prostatectomy will take place within 14 days of the last dose of OGX-011."}, 'eligibilityModule': {'sex': 'MALE', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
