18F-DCFPyL PET/CT in High Risk and Recurrent Prostate Cancer

Background: Prostate cancer is the second leading cause of cancer deaths in American men. When prostate cancer is confined to the prostate there is a high chance of cure. However, it is outside the prostate or comes back after treatment, additional therapy may be needed. Current methods of imaging prostate cancer are limited. Researchers want to see if a radiotracer called 18F-DCFPyL can identify prostate cancer in patients who have a high risk of cancer spreading outside the prostate or who have signs of recurrent cancer after treatment. Objectives: To see if the radiotracer 18F-DCFyL can help identify prostate cancer in the body before or after therapy. Eligibility: Men ages 18 and older who have prostate cancer that has been newly diagnosed, or has relapsed after radiation or surgery Design: Participants will be divided into 2 groups. * Group 1 will be men with cancer that has been newly diagnosed as high risk by their doctor who are scheduled to have prostate removal surgery or undergo biopsy before radiation therapy. * Group 2 will be men who have presumed prostate cancer relapse after prostate removal surgery or radiation therapy. Both groups will have scans taken. Participants will lie still on a table in a machine that takes pictures of their body. 18F-DCFyL will be injected by intravenous (IV) line. Participants will be contacted for follow-up after scans. Participants in Group 1 may have surgery to remove their prostate gland or a biopsy to remove some prostate tissue. This procedure will be standard of care and is not a part of this study. They will also have an extra MRI scan of their prostate. For this, a tube, called an endorectal coil, will be placed in their rectum. Other tubes may be wrapped around the inside of their pelvis. A contrast agent will be given by IV. Participants in Group 2 may also undergo an MRI of the pelvis and may have a biopsy of abnormalities found on the 18F-DCFyL scan. Participants will have data about their prostate cancer collected for up to 1 year.

18F-DCFPyL PSMA- Versus 18F-NaF-PET Imaging for Detection of Metastatic Prostate Cancer

Background: Prostate cancer is the second leading cause of cancer deaths in American men. Few options exist to create images of this type of cancer. Researchers think an experimental radiotracer called 18F-DCFPyL could find sites of cancer in the body. Objective: To see if 18F-DCFPyL can identify sites of prostate cancer in people with the disease. Eligibility: People ages 18 and older who have metastatic prostate cancer Design: Participants will be screened with: * Blood tests * Physical exam * Medical history Participants will be assigned to 1 of 2 groups based on their PSA. Participants will have 18F-DCFPyL injected into a vein. About 2 hours later they will have a whole-body Positron Emission Tomography/Computed Tomography (PET/CT). For the scan, they will lie on their back on the scanner table while it takes pictures of the body. This lasts about 50 minutes. On another day, participants will have 18F -NaF injected into a vein. About 1 hour later, they will have a whole-body PET/CT. Participants will be contacted 1 3 days later for follow-up. They may undergo PET/Magnetic Resonance Imaging (MRI) either after having a 18F-DCFPyL PET/CT, or in place of PET/CT imaging. A tube may be placed in the rectum. More coils may be wrapped around the outside of the pelvis. If the 18F-DCFPyL PET/CT is positive participants will be encouraged to undergo a biopsy of one of the tumors. The biopsy will be taken through a needle put through the skin into the tumor. Participants will be followed for 1 year. During this time researchers will collect information about their prostate cancer, such as PSA levels and biopsy results. About 4-6 months after scanning is completed, participants may have a tumor biopsy. The biopsy will be taken through a needle put through the skin into the tumor. ...

Collection of Blood From Patients With Prostate Cancer

Background: * It is not fully understood why prostate cancer in some men becomes androgen-independent (no longer responds to anti-androgen medication), but genetics likely plays an important role. * Genes contain the hereditary information that is passed down from parents to children. Although everyone has the same set of genes, individuals can have different forms of the same gene. * Differences in genes may explain, at least in part, why some people develop a more aggressive form of prostate cancer than others. Objectives: -To obtain blood samples from patients with prostate cancer to try to identify gene differences associated with progression to the androgen independent state. Eligibility: -All participants participating in NCI prostate cancer protocols. Design: * Participants with prostate cancer are evaluated in the NCI s Medical Oncology Clinic. * Blood samples are collected at the initial visit or at follow-up visits. * DNA (genetic material) and white blood cells are extracted from these samples to be used for genotyping and establishment of cell lines. * Gene variations are correlated with prostate cancer prognosis and prognostic indicators.

A Study Testing if Patients With Advanced Prostate Cancer Who Are Responding Well to Combination Treatment Can Safely Reduce Their Medication to a Single Hormone Therapy, Compared to Continuing Their Current Drugs

The goal of this randomized comparative study (a study where participants are placed into groups by chance) is to find out if reducing treatment to androgen deprivation therapy (ADT)-a treatment that lowers testosterone-by itself works just as well as continuing the original combination of drugs. This study involves adult men with metastatic hormone-sensitive prostate cancer (prostate cancer that has spread to other parts of the body but still responds to hormone treatments) who have responded very well after 6 to 7 months of their initial two-drug or three-drug treatment. The main questions it aims to answer are: 1. Does reducing treatment to ADT alone work as well as the combination treatment at keeping the cancer from growing on imaging scans after 18 months, also known as radiographic progression-free survival (rPFS)? 2. Does reducing treatment to ADT alone work as well as the combination treatment at preventing a rise in prostate-specific antigen (PSA), known as PSA progression-free survival (PSA-PFS)? Researchers will compare a continuation group, which continues their initial two-drug or three-drug treatment, to a reduced-treatment group, which stops taking the androgen receptor pathway inhibitor (ARPI)-a drug that blocks the effects of hormones on cancer cells. Researchers want to see if reducing the treatment safely controls the cancer while lowering drug side effects and financial costs. Participants will: 1. Complete a 6- to 7-month initial period receiving a two-drug or three-drug treatment chosen by their doctor. 2. Have blood tests for PSA and testosterone, and undergo a specialized imaging scan called a prostate-specific membrane antigen positron emission tomography/computed tomography (PSMA PET/CT) scan, to confirm the treatment is working very well before being assigned to a study group. 3. Stop taking the ARPI drug if assigned to the reduced-treatment group, or continue their current medications if assigned to the continuation group. 4. Go to check-up visits every 3 months for the first 24 months to complete physical exams, blood tests, and quality-of-life surveys. 5. Have a PSMA PET/CT scan every 6 months after being put into a group to check if the cancer has grown.

Talazoparib Plus Enzalutamide After Progression to Prior ARPi in Metastatic Prostate Cancer

The purpose of this clinical trial is to determine the anti-tumor activity of talazoparib plus enzalutamide as first line treatment for metastatic castration resistant prostate cancer (mCRPC) in participants whose disease has progressed on Androgen Receptor Pathway Inhibitor (ARPI). The main questions it aims to answer are: * Does talazoparib plus enzalutamide improve efficacy in metastatic castration resistant prostate cancer (mCRPC) compared to enzalutamide alone? * What is the time to disease progression \[radiographic, Prostate Specific Antigen (PSA), clinical\] in participants treated with talazoparib plus enzalutamide after progression on abiraterone? * What medical problems do participants have when receiving talazoparib plus enzalutamide? Researchers will compare the combination of talazoparib and enzalutamide as a first-line treatment for mCRPC to see if the combination improves the PSA response rate and delays progression compared to enzalutamide alone. The safety and tolerability of the combination (talazoparib and enzalutamide) will also be studied
