Primary Outcome Measures :
  1. Objective Response Rate (ORR) [ Time Frame: From enrollment to primary completion of study (up to approximately 3 years) ]
  2. Prostate Specific Antigen (PSA) Response [ Time Frame: From enrollment to primary completion of study (up to approximately 3 years) ]

Secondary Outcome Measures :
  1. Duration of Response (DOR) [ Time Frame: From enrollment to completion of study (up to approximately 3 years and 6 months) ]
  2. Radiologic Progression-free Survival (rPFS) [ Time Frame: From enrollment to completion of study (up to approximately 3 years and 6 months) ]
  3. Overall Survival (OS) [ Time Frame: From enrollment to completion of study (up to approximately 3 years and 6 months) ]
  4. Clinical Benefit Rate (CBR), defined as the percentage of patients with a complete response (CR), partial response (PR) or stable disease (SD) according to modified RECIST 1.1 with no progression in bone per PCWG3 criteria [ Time Frame: From enrollment to primary completion of study (up to approximately 3 years) ]
  5. Time to PSA Progression [ Time Frame: From enrollment to primary completion of study (up to approximately 3 years) ]
  6. Trough plasma PK (Cmin) of rucaparib based on sparse sampling [ Time Frame: From enrollment to completion of study (up to approximately 3 years and 6 months) ]
  7. Safety and tolerability of rucaparib assessed by AEs reported; clinical laboratory investigations; Vital signs; 12-lead ECGs; Physical examinations; and ECOG performance status [ Time Frame: From enrollment to completion of study (up to approximately 3 years and 6 months) ]
    This is a composite outcome. It will be assessed by incidence, type, seriousness, and severity of AEs reported; clinical laboratory investigations (hematology, serum chemistry and urinalysis); Vital signs (blood pressure, heart rate, and body temperature); 12 lead ECGs; Physical examinations; and ECOG performance status
