Prostate Radiotherapy and Metastasis-Directed Therapy in Synchronous Oligometastatic Prostate Cancer

This is an ambispective, multicenter, observational real-world registry of patients with synchronous de novo oligometastatic prostate cancer, defined as prostate cancer with up to 10 extraregional metastatic lesions diagnosed at initial presentation or within 6 months of the primary diagnosis. The study will evaluate outcomes after comprehensive local and metastasis-directed treatment. Eligible patients receive definitive prostate-directed radiotherapy, which may include external-beam radiotherapy, external-beam radiotherapy with brachytherapy boost, or definitive prostate brachytherapy monotherapy in selected patients, together with stereotactic body radiotherapy to all identified extraregional metastatic lesions. Systemic therapy is given according to routine clinical practice and local multidisciplinary decisions. The registry is non-interventional. Participants are not assigned to treatment by the study protocol, and no experimental treatment, randomization, or protocol-mandated imaging schedule is used. The study collects de-identified data from routine medical records, including baseline disease characteristics, imaging, radiotherapy details, systemic therapy, radiographic progression, patterns of failure, subsequent treatments, adverse events, and survival. The study includes historical retrospective data, prospective follow-up of previously treated eligible patients, and prospective enrollment of newly eligible patients from the registry activation date. The main goal is to describe where and when prostate cancer progresses after comprehensive treatment of the prostate and all visible metastatic lesions, and to identify clinical and treatment-related factors associated with disease control and adverse events.

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. ...

Study of Sipuleucel-T With or Without Continuing New Hormonal Agents in Metastatic Prostate Cancer

This study is designed to test the hypothesis that using Sipuleucel-T (Provenge) in combination with new hormonal agents (NHA) (abiraterone, enzalutamide, apalutamide) for the treatment of participants with asymptomatic metastatic castration resistant prostate cancer (mCRPC) and no visceral metastases would enhance the activation of antigen presenting cells (APC) by sipuleucel-T.

Androgen Receptor Directed Therapy on Cognitive Function in Patients Treated With Darolutamide or Enzalutamide

This is a prospective, randomized, open-label phase II study comparing cognitive outcomes between men with metastatic and non-metastatic castration resistant prostate cancer (CRPC) or metastatic hormone sensitive prostate cancer (HSPC). Approximately 132 patients will be enrolled. Eligible patients will be randomized in a 1:1 fashion to treatment with enzalutamide 160 mg orally daily or darolutamide 600 mg orally twice daily, in combination with standard LHRH agonist based treatment. Cognitive assessments will be performed using modules from Cambridge Neuropsychological Test Automated Battery (CANTAB) an internationally recognized software for assessing cognitive function and impairment.

A Study of Tarlatamab for People With Prostate Cancer

The researchers are doing this study to find out whether tarlatamab is an effective treatment for Delta-like Protein 3 (DLL3)-positive prostate cancer that has spread to other parts of your body (metastasized) and has either come back after treatment (relapsed) or not responded to treatment (refractory).

Low Dose Naltrexone (LDN) for Management of Fatigue in Prostate Cancer Patients on Androgen Deprivation Therapy (ADT)

The study is being done to see if a small daily dose of naltrexone (LDN, 3 mg pill) can help reduce tiredness (fatigue) in men with prostate cancer. All men in this study are being treated with hormone therapy (also called androgen deprivation therapy, or ADT). Some may also be taking newer hormone medicines such as apalutamide, daralutamide, enzalutamide, or abiraterone.

Study of PSMA-targeted Therapy and Androgen Receptor Suppression in Low-volume Metastatic ProstatE Cancer: SPARKLE Trial

This phase II trial tests leuprolide acetate alone versus in combination with 177Lu-PSMA-617, with or without abiraterone acetate and prednisone, for the treatment of hormone-sensitive prostate cancer has spread to a limited number of anatomic sites at the time of initial diagnosis (de novo low volume metastasis) or that has come back after a period of improvement (recurrent). Standard of care treatment for prostate cancer usually includes androgen deprivation therapy, with or without abiraterone acetate and prednisone. Leuprolide acetate is a form of androgen deprivation therapy. It blocks the body from making testosterone (a male hormone) and estradiol (a female hormone). It may stop the growth of prostate cancer cells that need testosterone to grow. 177Lu-PSMA-617 is a type of radioconjugate drug. Upon administration, vipivotide tetraxetan targets and binds to prostate specific membrane antigen (PSMA)-expressing tumor cells. Upon binding, PSMA-expressing tumor cells are destroyed by 177Lu through the specific delivery of radiation. PSMA, a tumor-associated antigen and type II transmembrane protein, is overexpressed on prostate tumor cells. Abiraterone acetate is a type of anti-androgen drug. It blocks tissues from making androgens (male hormones), such as testosterone. This may cause the death of cancer cells that need androgens to grow. Prednisone is in a class of medications called corticosteroids. It is used to reduce inflammation and lower the body's immune response to help lessen the side effects of chemotherapy drugs. Giving 177Lu-PSMA-617 in combination with leuprolide acetate, with or without abiraterone acetate and prednisone, may be more effective at treating patients with recurrent or de novo low volume metastatic hormone-sensitive prostate cancer than giving leuprolide acetate alone.

Neo-DAB: Darolutamide and Abemaciclib in Prostate Cancer

This research study is trying to determine the safety and efficacy of the combination of two oral drugs, abemaciclib and darolutamide, with androgen deprivation therapy (ADT) in the treatment of metastatic, non-metastatic, and advanced prostate cancers. The first phase of the study is to establish a recommended dose for the second phase. The names of the study drugs and interventions involved in this study are: * Darolutamide * Abemaciclib * Androgen deprivation therapy (ADT) - this includes several different treatments, including Gonadotropin-Releasing Hormone (GnRH) antagonists and agonists It is expected that about 93 people will take part in the research study. Treatment is expected to last 6 months with a follow up period of up to 4.5 years.

First-in-human Diagnostic Imaging Profile of the Theranostic Pair [68Ga]Ga-DOTA-STR-17126 and Low Dose [177Lu] Lu-DOTA-STR-17126 in Patients With Advanced or Metastatic Cancer

This is an open-label, first-in-human, exploratory Phase 0 study evaluating the safety and diagnostic imaging performance of the DOTA-STR-17126 theranostic pair in patients with advanced or metastatic breast or prostate cancer. The study investigates \[68Ga\]Ga-DOTA-STR-17126 for PET imaging and, in patients with positive GRPR uptake, a low dose of \[177Lu\]Lu-DOTA-STR-17126 for SPECT imaging and dosimetry. The primary objective is to assess safety and tolerability. Secondary objectives include evaluation of imaging quality, biodistribution, pharmacokinetics, and radiation dosimetry. Exploratory objectives assess correlations between GRPR expression in tumour tissue and imaging uptake. The study is conducted at a single centre in Australia, with 12 evaluable participants (up to 20 enrolled), and supports the development of a GRPR-targeted theranostic approach for personalised cancer management.

The Effect of a Structured Strength and Endurance Training Program on Quality of Life, Fitness, Blood Parameters and Survival in Prostate Cancer Patients

Prostate cancer is the second most common cancer among men. Many patients experience a significantly reduced quality of life due to either the cancer itself or the side effects of treatment. These side effects can include tiredness, weight gain, loss of muscle and strength, bone weakness, depression, reduced sexual function, and increased risk of heart problems. A commonly used treatment called androgen deprivation therapy, which reduces the levels of male hormones, can make these symptoms worse. Previous research has shown that physical exercise-both strength training and endurance training-can help improve physical and mental well-being in men with prostate cancer. Regular exercise has also been shown to improve body composition, cardiovascular health, and reduce cancer-related fatigue. Some studies even suggest that exercise might support the immune system and slow down the progression of cancer. The aim of this clinical trial is to find out whether a specific combination of resistance and aerobic training can help improve quality of life and health outcomes in men with prostate cancer. The exercise program is designed to be performed at home using simple equipment like resistance bands and bodyweight exercises, along with high-intensity interval training for endurance. Participants are asked to train three to six days a week. 150 men with prostate cancer at various stages of the disease will be included. These men will be randomly divided into two groups: two-thirds will receive the exercise program (intervention group), and one-third will continue with their usual care without the program (control group). The initial training period lasts 12 weeks and will be repeated to ensure that all participants in the exercise group train for at least six months. After that, they will be encouraged to keep training on their own. The main goal of the study is to see if the exercise program leads to improvements in quality of life, physical fitness, body composition, and markers of immune function. It will also be analyzed how well the participants stick to the program, whether a longer training period has more benefits, how physically active the participants are overall, and how the program might affect other health and cancer-related outcomes. The underlying hypothesis is that a structured, home-based resistance and aerobic training program will improve quality of life, physical fitness, body composition, immune function, and possibly cancer-related outcomes in men with prostate cancer.

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.

Duration of Androgen Receptor Pathway Inhibitor and ADT With Metastasis Directed Therapy in Oligometastatic Cancer of the Prostate (DIRECT)
