Description:

Up to 30 men with metastatic prostate cancer will undergo up to 2 FTT PET/CT scans to look at PARP activity in sites of known cancer. Subjects will undergo a baseline scan prior to starting new therapy and a second, optional, post-therapy scan 1-21 days after the start of treatment. Tissue from a clinical or research biopsy will be compared to imaging measures, if available.
