“A Study to Determine Frequency of DNA-repair Defects in Men With Metastatic Prostate Cancer”
The purpose of this study is to evaluate the prevalence of 4 or more DNA-repair defects in a population of men with metastatic Prostate Cancer (PC) and to use the variants reported to assess biomarker eligibility for niraparib interventional studies.
Saliva, Blood, or Existing Tissue Sample Collection and Analysis
Saliva or blood sample (or both) or existing tissue sample analysis will be collected from the participants with metastatic PC for genetic testing to determine if DNA-repair defects are present.
