Conditions

Metastatic Prostate Cancer

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.

Interventions

OTHERSaliva, 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.

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

Design outcomes

Primary

MeasureTime frameDescription
Percentage of Participants with 4 or more DNA-repair Gene Defects with Metastatic Prostate Cancer as an Estimate for PrevalenceApproximately 2.4 yearsPercentage 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.
Percentage of Participants who Meet Biomarker Eligibility Criteria for Other Niraparib Interventional StudiesApproximately 2.4 yearsPercentage of participants who meet biomarker eligibility criteria for other niraparib interventional studies will be assessed.

Secondary

MeasureTime frameDescription
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 PrevalenceApproximately 2.4 yearsPercentage 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.
Percentage of Participants with 1 or more DNA-repair gene defects with Metastatic Prostate Cancer as an Estimate for PrevalenceApproximately 2.4 yearsPercentage 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.
