Relugolix and Enzalutamide in Combination With Radiation Therapy for the Treatment of Very High Risk Prostate Cancer, OPTIMAL Trial
This phase II trial tests how well relugolix and enzalutamide, in combination with radiation therapy, works in treating patients with very high risk prostate cancer. Relugolix is a form of androgen deprivation therapy. It prevents the release of testosterone, a hormone required to sustain prostate growth. Reducing testosterone levels may inhibit the proliferation of prostate tumor cells that need testosterone to grow. Enzalutamide is an androgen receptor signaling inhibitor. It inhibits the activity of prostate tumor cell receptors, which may reduce proliferation of prostate tumor cells. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Adding relugolix and enzalutamide to radiation therapy may be more effective at treating patients with very high risk prostate cancer than giving any of these treatments alone.

Testing Shorter Duration Radiation Therapy Versus the Usual Radiation Therapy in Patients With High Risk Prostate Cancer
This phase III trial compares stereotactic body radiation therapy (SBRT), (five treatments over two weeks using a higher dose per treatment) to usual radiation therapy (20 to 45 treatments over 4 to 9 weeks) for the treatment of high-risk prostate cancer. SBRT uses special equipment to position a patient and deliver radiation to tumors with high precision. This method may kill tumor cells with fewer doses over a shorter period of time. This trial is evaluating if shorter duration radiation prevents cancer from coming back as well as the usual radiation treatment.

A Study To Evaluate Hypofractionated Proton Therapy Or IMRT For Recurrent, Oligometastatic Prostate Cancer
This phase II trial studies the side effects of radiation therapy \[hypofractionated proton beam radiation therapy (PBRT) or intensity-modulated radiation therapy (IMRT)\] for the treatment of prostate cancer that has come back (recurrent) or that has spread to a limited number of sites (oligometastatic) following primary localized treatment. Hypofractionated PBRT delivers smaller doses of radiation therapy over time and may kill more tumor cells and have fewer side effects. IMRT uses high energy x-rays to kill tumor cells and shrink tumors. This trial is being done to find out if a shorter course of radiation therapy is better with fewer side effects for patients with recurrent prostate cancer.

Golimumab and Apalutamide for the Treatment of Castration-Resistant Prostate Cancer, TRAMP Study
This phase II trial tests how well golimumab and apalutamide work in treating patients with castration resistant prostate cancer. Golimumab is in a class of medications called tumor necrosis factor (TNF) inhibitors. It works by blocking the action of TNF, a substance in the body that causes inflammation. Apalutamide is in a class of medications called androgen receptor inhibitors. It works by blocking the effects of androgen (a male reproductive hormone) to stop the growth and spread of cancer cells. Giving golimumab and apalutamide may work better in treating patients with castration-resistant prostate cancer.

Focal Therapy With Stereotactic Body Radiation Therapy (SBRT) for Patients With a Single Prostate Tumor
Background: The current standard treatment of prostate cancer is either surgery or radiation. Typically, this includes either the removal or radiation of the whole prostate gland. Many people now seek out focal therapy options to decrease the side effects of treatment. Until now, several forms of physical destruction with heat (thermal ablation), cold (cryotherapy), sound waves (HIFU), laser (FLA), and electrical energy (IRE). A new type of radiation (SBRT) may be an effective way to cure men of early-stage prostate cancer with fewer side effects than standard treatments. Objective: To see how people with untreated localized prostate cancer will respond to focal therapy with SBRT. Eligibility: People aged 18 years and older with untreated localized prostate cancer (prostate cancer which has not spread outside of the prostate gland). Design: * Participants will undergo screening including blood tests, an MRI, a PSMA PET/CT (18F-DCFPyL), and a biopsy. * Small, non-radioactive, gold seeds about the size of a grain of rice will be placed in and/or around the tumor to help target the radiation treatment. * Radiation (SBRT) will occur in 2 separate sessions about 1 week apart. No sedation is used, these sessions are painless. Each session will take about 1-2 hours. Participants can go home afterwards. * Follow-up will continue for 2 years with repeat scans (MRI and PSMA PET/CT) and blood (PSA) tests. * After two years, a biopsy will be done to understand the impact of this new treatment on prostate cancer.

Increasing the Dose of Survivorship Care Planning in Improving Care and Outcomes in Prostate Cancer Survivors Receiving Androgen Deprivation Therapy
This trial studies how well increasing the dose of survivorship care planning improves care and outcomes in prostate cancer survivors receiving radiation therapy and androgen deprivation therapy. There is a need for coordinated care between the cancer care team with the primary care team. This is especially important for prostate cancer survivors who need routine cancer care follow-up with their radiation oncologist and also coordinated routine follow-up with their primary care provider (PCP). This is important because androgen deprivation therapy increases a patient's risk for developing diabetes, hypercholesterolemia, and cardiovascular events. Increasing the dose of survivorship may improve care and outcomes of cancer survivors than standard practices.

Risk Stratified De-escalated Hormone Therapy With Radiation Therapy for the Treatment of Prostate Cancer
This phase II trial tests how well risk based de-escalated hormone therapy (i.e., fewer treatments) with radiation works in treating patients with prostate cancer. Androgen deprivation therapy (ADT), such as gonadotropin-releasing hormone analogs (LHRH) and abiraterone acetate (Zytiga), lower the amount of the male hormone, testosterone, made by the body. This may help kill or stop the growth of tumor cells that need testosterone to grow. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Research has shown that long-term ADT is beneficial for patients with high-risk prostate cancer. However, there are few studies that determine ADT treatment based on risk factors. Giving risk based de-escalated ADT with radiation therapy may be as effective as giving more ADT in treating high-risk prostate cancer.

Androgen Deprivation Therapy (Relugolix) for the Improvement of Diagnostic Imaging (PSMA PET/CT Scan) in Patients With High Risk or Very High Risk Prostate Cancer, The EnrichPSMA Trial
This phase II trial studies how well a short course of androgen deprivation therapy (ADT) with relugolix works in increasing expression of prostate-specific membrane antigen (PSMA) and improving diagnostic imaging with PSMA positron emission tomography (PET)/computed tomography (CT) in patients with high risk or very high risk prostate cancer. PSMA PET/CT has become the standard of care in imaging for high-risk prostate cancer. However, a limitation of PSMA PET/CT is its ability to detect cancer that has spread to the lymph nodes. PSMA is a protein that is usually found on the surface of normal prostate cells but is found in higher amounts on prostate tumor cells. Studies have shown that expression of PSMA is regulated by androgens (male reproductive hormones). Relugolix binds to gonadotropin-releasing hormone receptors in the pituitary gland, which blocks the pituitary gland from making the hormones follicle-stimulating hormone and luteinizing hormone. This causes the testicles to stop making testosterone. Relugolix may stop the growth of tumor cells that need testosterone to grow. PSMA PET/CT is an imaging procedure that is used to help find prostate tumor cells in the body. For this procedure, a cell-targeting molecule linked to a radioactive substance (flotufolastat F 18 in this trial) is injected into the body and travels through the blood. It attaches to PSMA that is found on the surface of prostate tumor cells. PET/CT scanners detect high concentrations of the radioactive molecule and shows where the prostate tumor cells are in the body. Giving a short course of ADT with relugolix may increase PSMA expression to detect smaller areas of prostate cancer that were not previously detected.
