Eligibility Criteria

Age 18+ · Male Participants · 10 Total Inclusion Criteria

Mark “Yes” if the following statements are true for you:
Participants must have tumor accessible for biopsy and be agreeable to baseline tumor biopsy; a metastatic focus is preferred but if not available and prostate is still intact prostate biopsy can be performed.
Availability of FFPE archival tumor specimens.
Participants must have histologically or cytologically confirmed adenocarcinoma of the prostate.
You have castrate levels of serum testosterone < 50 ng/dL.
You have two or more new lesions on bone scan.
