Brief Summary:
The purpose of this study is to evaluate the prevalence of 4 or more DNA-repair gene defects in a population of men with metastatic Prostate Cancer (PC) and to use the reported DNA-repair gene defects to assess biomarker eligibility for niraparib interventional studies.

Group/Cohort Intervention/treatment
Participants with Metastatic Prostate Cancer
Participants with metastatic prostate Cancer (PC) will be evaluated for the prevalence of DNA-repair gene defects (DRDs) and will be assessed for biomarker eligibility status for niraparib interventional studies. Participants will be consented to saliva, blood, and/or archival tumor tissue testing for the presence or absence of DNA-repair gene defects.
Other: Saliva, Blood, or and/or Archival Tumor Tissue Collection and Analysis
Saliva, blood, and/or archival tumor tissue will be collected from the participants with metastatic PC for genomic testing to confirm DRD status.




Primary Outcome Measures :
  1. Percentage of Participants with 4 or more DNA-repair Gene Defects with Metastatic Prostate Cancer as an Estimate for Prevalence [ Time Frame: Approximately 2.4 years ]
    Percentage of participants with 4 or more Deoxyribonucleic acid (DNA)-repair gene defects with metastatic Prostate Cancer (PC) as an estimate for prevalence will be assessed. A saliva, blood, and/or archival tumor tissue sample will be collected for genomic testing to confirm DNA-repair gene defect (DRD) status.

  2. Percentage of Participants who Meet Biomarker Eligibility Criteria for Other Niraparib Interventional Studies [ Time Frame: Approximately 2.4 years ]
    Percentage of participants who meet biomarker eligibility criteria for other niraparib interventional studies will be assessed.


Secondary Outcome Measures :
  1. Percentage of Participants with 4 or more DNA-repair Gene Defects with Metastatic Castration-Resistant Prostate Cancer (mCRPC) and with Metastatic Hormone Sensitive PC (HSPC) as an Estimate for Prevalence [ Time Frame: Approximately 2.4 years ]
    Percentage of participants with 4 or more DRDs with mCRPC and HSPC as an estimate for prevalence will be assessed. A saliva, blood, and/or archival tumor tissue sample will be collected for genomic testing to confirm DRD status.

  2. Percentage of Participants with 1 or more DNA-repair gene defects with Metastatic Prostate Cancer as an Estimate for Prevalence [ Time Frame: Approximately 2.4 years ]
    Percentage of participants with 1 or more DRDs with metastatic PC as an estimate for prevalence will be assessed. Saliva, blood, and/or archival tumor tissue sample will be collected for genomic testing to confirm DRD status.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population
Study population consists of male participants diagnosed with metastatic prostate cancer who will be evaluated for the prevalence for DNA-repair gene defects.
Criteria

Inclusion Criteria:

  • Diagnosis of metastatic (Stage IV) prostate cancer (PC), confirmed by either biopsy of a metastatic tumor site or history of localized disease supported by metastatic disease on imaging studies (that is [i.e.], clearly noted in hospital/clinical records)
  • Signed Informed consent form (ICF)
  • No condition for which, in the opinion of the investigator, participation would not be in the best interest of the participant (for example [e.g.], compromise the well-being) or that could prevent, limit, or confound the protocol-specified assessments
  • Willing to provide a saliva, blood, and/or archival tumor tissue sample for genomic analysis
  • No prior poly (adenosine diphosphate [ADP]-ribose) polymerase inhibitor (PARPi) for the treatment of prostate cancer
  • No prior DNA-repair gene defect test results from a Janssen sponsored interventional trial
