    <textblock>
      This is a biomarker preselected, randomized, open-label, multicenter, phase II study in men&#xD;
      with metastatic castration resistant prostate cancer (mCRPC). Patients with tumors that have&#xD;
      ATM, BRCA1 and/or BRCA2 mutations/deletions/loss of heterozygosity will be randomized in a&#xD;
      1:1:1 fashion to each arm. Patients with mutations in noncanonical DNA repair genes including&#xD;
      FANCA, PALB2, RAD51, ERCC3, MRE11, NBN, MLH3, CDK12, CHEK2, HDAC2, ATR, PMS2, GEN1, MSH2,&#xD;
      MSH6, BRIP1, or FAM175A defects will be assigned to Arm IV with single agent olaparib.&#xD;

  <eligibility>
    <criteria>
      <textblock>
        Inclusion Criteria:&#xD;
&#xD;
          -  Ability to understand and the willingness to sign a written informed consent document&#xD;
             that is approved by the local institutional review board and HIPAA authorization for&#xD;
             the release of personal health information.&#xD;
&#xD;
          -  Histological or cytological proof of prostate adenocarcinoma (Note: small-cell&#xD;
             carcinoma of the prostate is not permitted)&#xD;
&#xD;
          -  Documented progressive mCRPC based on at least one of the following criteria:&#xD;
&#xD;
               1. PSA progression defined as 25% increase over baseline value with an increase in&#xD;
                  the absolute value of at least 2.0 ng/mL that is confirmed by another PSA level&#xD;
                  with a minimum of a 1 week interval and a minimum PSA of 2.0 ng/mL.&#xD;
&#xD;
               2. Progression of bidimensionally measurable soft tissue or nodal metastasis&#xD;
                  assessed within one month prior to registration by a CT scan or MRI.&#xD;
&#xD;
               3. Progression of bone disease (evaluable disease) (new bone lesion(s)) by bone&#xD;
                  scan.&#xD;
&#xD;
          -  Agree to undergo a biopsy of at least one metastatic site (fresh biopsy of primary&#xD;
             prostate only allowed if there is clear local disease and no other measurable disease&#xD;
             site or biopsiable bone lesion.) to determine DNA repair defects. (Please refer to the&#xD;
             Laboratory Manual for specific procedures). However:&#xD;
&#xD;
               1. Adequate archival metastatic or primary disease tumor tissue can be used if&#xD;
                  available in lieu of a new biopsy. These patients will only be eligible for&#xD;
                  protocol therapy if the biopsy has tumor that is positive for DNA repair defects.&#xD;
&#xD;
               2. Patients with known DNA damage repair defects based on prior appropriately&#xD;
                  validated metastatic or prostate tissue analysis may be used in lieu of new&#xD;
                  biopsy/analysis based on central site evaluation of quality of the biopsy and&#xD;
                  analysis.&#xD;
&#xD;
               3. Patients with known germline DNA repair defects are eligible without a biopsy.&#xD;
                  However it will be highly desirable that they undergo a metastatic (or fresh&#xD;
                  prostate biopsy if there is clear local disease and no other measurable disease&#xD;
                  site or biopsiable bone lesion) disease biopsy to better define the scope of the&#xD;
                  DNA repair defects in the current disease context.&#xD;
&#xD;
          -  ECOG status of 0-2 (Appendix A: Performance Status Criteria).&#xD;
&#xD;
          -  Adequate organ function as defined below obtained within 14 days of registration:&#xD;
&#xD;
        ANC &gt; or = 1500/µl Hemoglobin ≥ 10.0 g/dL WBC &gt; 3x10^9/L Platelet count 100,000/µl&#xD;
        Creatinine ≥51 mL/min estimated using the Cockcroft-Gault equation Potassium ≥ 3.5 mmol/L&#xD;
        (within institutional normal range) Bilirubin within normal institutional limits (or &lt;2X&#xD;
        the upper limit of normal (ULN) in those with Gilbert's disease) AST (SGOT) / ALT (SGPT) ≤&#xD;

        ULN&#xD;
&#xD;
          -  The effects of abiraterone, olaparib or the combination of both on the developing&#xD;
             human fetus at the recommended therapeutic dose are unknown. Men must agree to use&#xD;
             adequate contraception prior to study entry, for the duration of study participation&#xD;
             and for at least 3 months thereafter.&#xD;
&#xD;
          -  Patients must discontinue antiandrogen therapy (i.e., flutamide, bicalutamide,&#xD;
             nilutamide) for at least 4 weeks prior to registration with no evidence of a falling&#xD;
             PSA after washout.&#xD;
&#xD;
          -  Serum testosterone &lt; 50 ng/dL. Patients must continue primary ADT with an LHRH&#xD;
             analogue (agonist or antagonist) if they have not undergone orchiectomy.&#xD;

             must have recovered from all side effects at the time of registration (e.g. back to&#xD;
             baseline or grade 1) .&#xD;
&#xD;
          -  Patient is willing and able to comply with the protocol for the duration of the study&#xD;
             including undergoing treatment and scheduled visits and examinations including follow&#xD;

&#xD;
          -  Patients who are HIV-positive on combination antiretroviral therapy because of the&#xD;
             potential for pharmacokinetic interactions with olaparib. In addition these patients&#xD;

This is a biomarker preselected, randomized, open-label, multicenter, phase II study in men
      with metastatic castration resistant prostate cancer (mCRPC). Patients with tumors that have
      ATM, BRCA1 and/or BRCA2 mutations/deletions/loss of heterozygosity will be randomized in a
      1:1:1 fashion to each arm. Patients with mutations in noncanonical DNA repair genes including
      FANCA, PALB2, RAD51, ERCC3, MRE11, NBN, MLH3, CDK12, CHEK2, HDAC2, ATR, PMS2, GEN1, MSH2,
      MSH6, BRIP1, or FAM175A defects will be assigned to Arm IV with single agent olaparib.
allocation: Randomized
intervention model: Crossover Assignment
primary purpose: Treatment
masking: None (Open Label)
measure: Objective Progression Free Survival (PFS)
time frame: Up to 2 years
description: Evaluate the objective PFS of abiraterone/prednisone, olaparib or the combination abiraterone/prednisone + olaparib in mCRPC patients with canonical DNA repair defects in BRCA1, BRCA2, or ATM.
measure: Measurable disease response rate by RECIST
time frame: Up to 2 years
description: Objective disease response (complete response [CR] + partial response [PR]) assessed using RECIST 1.1.
measure: PSA response rate
time frame: Up to 2 years
description: PSA response rate (CR + PR) will be measured.
measure: Rate of undetectable PSA
time frame: Up to 2 years
description: The rate of undetectable PSA (CR) will be measured.
measure: Poly[ADP-ribose] polymerase (PARP) inhibition
time frame: Up to 2 years
description: Evaluate if noncanonical DNA repair defects have clinical susceptibility to PARP inhibition alone.
measure: Incidence of Adverse Events
time frame: Up to 2 years
description: To evaluate the safety of the combination of abiraterone/prednisone + olaparib combination therapy. Adverse events will be assessed by the National Cancer Institute's CTCAE 4.0.
measure: The post progression response rate with cross over to olaparib or abiraterone
time frame: Up to 2 years
description: The response rate will be evaluated in patients who cross over to olaparib or abiraterone post progression on therapy with abiraterone or olaparib respectively by treatment arm.
measure: The post progression PFS with cross over to olaparib or abiraterone
time frame: Up to 2 years
description: The PFS will be evaluated in patients who cross over to olaparib or abiraterone post progression on therapy with abiraterone or olaparib respectively by treatment arm.
measure: Qualitative toxicities
time frame: Up to 2 years
description: Adverse Event summaries will be reported by treatment arm and organized by body system, frequency of occurrence, intensity (i.e., severity grade), and causality or attribution. Treatment exposure will be summarized for all patients, including dose administration, number of cycles, dose modifications or delays, and duration of therapy.
