Testing the Combination of the Anti-cancer Drugs XL184 (Cabozantinib) and Nivolumab in Patients With Advanced Cancer and HIV
This phase I trial investigates the side effects of cabozantinib and nivolumab in treating patients with cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) and who are undergoing treatment for human immunodeficiency virus (HIV). Cabozantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving cabozantinib and nivolumab may shrink or stabilize cancer in patients undergoing treatment for HIV.

Testing the Addition of a New Anti-Cancer Drug, Niraparib, to the Usual Treatment (Hormone and Radiation Therapy) for Prostate Cancer With a High Chance of Recurring
This is a phase I-II trial to find the safety and activity of adding a new drug (neraparib) to the usual treatment (radiation combined with male hormone deprivation therapy) in lowering the chance of prostate cancer growing or returning. Niraparib is an inhibitor of PARP, an enzyme that helps repair deoxyribonucleic acid (DNA) when it becomes damaged. Blocking PARP may help keep cancer cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a type of targeted therapy. Adding niraparib to the usual care may lower the chance of prostate cancer growing or returning.

Conventional or Hypofractionated Radiation Therapy in Treating Patients With Prostate Cancer
This phase III trial studies how well hypofractionated radiation therapy works compared to the conventional one in treating patients with prostate cancer. Radiation therapy uses high energy beams to kill tumor cells and shrink tumors. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells and have fewer side effects.

Androgen Ablation Therapy With or Without Niraparib After Radiation Therapy for the Treatment of High-Risk Localized or Locally Advanced Prostate Cancer
This phase II trial studies the effect of androgen ablation therapy with or without niraparib after standard of care radiation therapy in treating patients with prostate cancer that has not spread to other parts of the body (localized) or that has spread to nearby tissue or lymph nodes (locally advanced). Androgen ablation therapy (also known as hormone therapy) lowers the levels of male hormones called androgens in the body. Androgens stimulate prostate cancer cells to grow. There are 2 types of androgen ablation therapy given in this study: AAP + ADT and Apa + ADT. AAP + ADT is the treatment combination of the drugs abiraterone acetate and prednisone (AAP) given with androgen deprivation therapy (ADT, also known as androgen deprivation therapy or androgen suppression medication, which is used as standard of care to lower testosterone levels in men with high risk localized or metastatic prostate cancer). Apa + ADT is the treatment combination of the drug apalutamide (Apa) given with ADT. Androgen ablation therapy with or without niraparib after radiation therapy may help to control the disease in patients with prostate cancer.

Testosterone Replacement Therapy for the Treatment of Low Testosterone in Hypogonadal Men With Localized Prostate Cancer on Active Surveillance
This phase IV trial studies the effects of testosterone replacement therapy (TRT) on treatment outcomes in hypogonadal men with prostate cancer that has not spread to other parts of the body (localized) and who are on active surveillance (AS). AS in prostate cancer involves closely watching the patient's condition through regular physical exams and blood tests, but not giving treatment unless there are changes in test results. It can be a practical alternative to treatment in localized prostate cancer. Hypogonadal men have low testosterone associated with symptoms such as low libido and erectile problems. TRT can be used to treat hypogonadism by increasing testosterone levels, which may improve associated symptoms. TRT is often not used in men with prostate cancer due to concerns it may lead to the cancer growing or spreading. This may lead hypogonadal men to have a poor quality of life or to discontinue AS. TRT may improve treatment and quality of life outcomes in hypogonadal men with localized prostate cancer on active surveillance.

Measuring the Effects of Talazoparib in Patients With Advanced Cancer and DNA Repair Variations
This phase II trial studies if talazoparib works in patients with cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) and has mutation(s) in deoxyribonucleic acid (DNA) damage response genes who have or have not already been treated with another PARP inhibitor. Talazoparib is an inhibitor of PARP, a protein that helps repair damaged DNA. Blocking PARP may help keep cancer cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a type of targeted therapy. All patients who take part on this study must have a gene aberration that changes how their tumors are able to repair DNA. This trial may help scientists learn whether some patients might benefit from taking different PARP inhibitors "one after the other" and learn how talazoparib works in treating patients with advanced cancer who have aberration in DNA repair genes.

Testing the Addition of the Drug Apalutamide to the Usual Hormone Therapy and Radiation Therapy After Surgery for Prostate Cancer, INNOVATE Trial
This phase III trial studies whether adding apalutamide to the usual treatment improves outcome in patients with lymph node positive prostate cancer after surgery. Radiation therapy uses high energy x-ray to kill tumor cells and shrink tumors. Androgens, or male sex hormones, can cause the growth of prostate cancer cells. Drugs, such as apalutamide, may help stop or reduce the growth of prostate cancer cell growth by blocking the attachment of androgen to its receptors on cancer cells, a mechanism similar to stopping the entrance of a key into its lock. Adding apalutamide to the usual hormone therapy and radiation therapy after surgery may stabilize prostate cancer and prevent it from spreading and extend time without disease spreading compared to the usual approach.

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.

Aspirin and Rintatolimod With or Without Interferon-alpha 2b in Treating Patients With Prostate Cancer Before Surgery
This phase II trial studies how well enteric-coated (EC) aspirin and rintatolimod with or without interferon-alpha 2b work in treating patients with prostate cancer before surgery. EC Aspirin may help to keep the prostate cancer from coming back. Rintatolimod may stimulate the immune system and interfere with the ability of tumor cells to grow and spread. Interferon-alpha 2b may improve the body's natural response to infections and may slow tumor growth. It is not yet known how well rintatolimod, EC aspirin, and interferon-alpha 2b work in treating patients with prostate cancer undergoing surgery.

Two Studies for Patients With High Risk Prostate Cancer Testing Less Intense Treatment for Patients With a Low Gene Risk Score and Testing a More Intense Treatment for Patients With a High Gene Risk Score, The PREDICT-RT Trial
This phase III trial compares less intense hormone therapy and radiation therapy to usual hormone therapy and radiation therapy in treating patients with high risk prostate cancer and low gene risk score. This trial also compares more intense hormone therapy and radiation therapy to usual hormone therapy and radiation therapy in patients with high risk prostate cancer and high gene risk score. Apalutamide may help fight prostate cancer by blocking the use of androgen by the tumor cells. Radiation therapy uses high energy rays to kill tumor cells and shrink tumors. Giving a shorter hormone therapy treatment may work the same at controlling prostate cancer compared to the usual 24 month hormone therapy treatment in patients with low gene risk score. Adding apalutamide to the usual treatment may increase the length of time without prostate cancer spreading as compared to the usual treatment in patients with high gene risk score.

PI3Kbeta Inhibitor AZD8186 and Docetaxel in Treating Patients Advanced Solid Tumors With PTEN or PIK3CB Mutations That Are Metastatic or Cannot Be Removed by Surgery
This phase I trial studies the side effects and best dose of PI3Kbeta inhibitor AZD8186 when given together with docetaxel in treating patients with solid tumors with PTEN or PIK3CB mutations that have spread to other places in the body (metastatic) or cannot be removed by surgery. PI3Kbeta inhibitor AZD8186 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving PI3Kbeta inhibitor AZD8186 and docetaxel may work better in treating patients with solid tumors.

A Precision Medicine Approach (SMMART-ACT) for the Treatment of Patients With Advanced Sarcoma, Prostate, Breast, Ovarian or Pancreatic Cancer
This phase II trial tests the how well a precision medicine approach (serial measurements of molecular and architectural response to therapy \[SMMART\])-adaptive clinical treatment \[ACT\]) works in treating patients with sarcoma, prostate, breast, ovarian or pancreatic cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). SMMART testing uses genetic and protein tests to learn how cancer changes and to understand what drugs may work against a person's cancer or why drugs stop working. These test results are reviewed by a group of physicians and scientists during a SMMART tumor board who then recommend precision therapy.

Peer Navigation for the Support of Metastatic Prostate Cancer Patients Undergoing Genetic Evaluation
This clinical trial evaluates whether having a trained peer navigator helps African American men with prostate cancer that has spread to other parts of the body (metastatic) understand and navigate the genetic testing process better than not having a peer navigator. Genetic testing for men with prostate cancer is very important for making treatment and management decisions. However, understanding the risks, benefits, and steps of genetic counseling and testing can be very challenging for patients. African American men are especially less likely to participant in genetic testing due to lack of awareness or understanding, cultural beliefs, finances, or mistrust of the healthcare system. A peer navigator, someone who helps a patient through the information and the process, may be helpful to some men. This study evaluates whether having a peer navigator throughout the genetic evaluation process helps patients understand and engage in the process more.

Accuracy of 18F-rhPSMA-7.3 PET/ MRI for Prediction of Lymph Node Metastasis in Localized High-Risk Prostate Cancer
This clinical trial evaluates the use of an imaging scan (18F-rhPSMA-7.3 positron emission tomography \[PET\]/magnetic resonance imaging \[MRI\]) for identifying patients who are at risk of having their disease spread to the lymph nodes in those undergoing radical prostatectomy for prostate cancer that has not spread to other parts of the body (localized). Prostate specific membrane antigen (PSMA) PET/computed tomography (CT) has emerged as an option to stage newly diagnosed high risk prostate cancer patients. PSMA PET/CT has demonstrated improved diagnostic accuracy for identifying metastasis. PET is procedure in which a small amount of radioactive glucose (sugar) is injected into a vein, and a scanner is used to make detailed, computerized pictures of areas inside the body where the glucose is used. Because cancer cells often use more glucose than normal cells, the pictures can be used to find cancer cells in the body. MRI is procedure in which radio waves and a powerful magnet linked to a computer are used to create detailed pictures of areas inside the body. These pictures can show the difference between normal and diseased tissue. This study may help researchers learn whether 18F-rhPSMA-7.3 PET/ MRI may improve predicting which patients are at risk of lymph node metastases and who are suitable candidates for pelvic lymph node dissection in patients with localized high-risk prostate cancer undergoing radical prostatectomy.

Adaptive Radiation Therapy (ART) Stereotactic Ablative Body Radiotherapy (SABR) for Primary Localized Prostate Cancer
This clinical trial evaluates changes in quality of life after two treatments with near margin-less adaptive radiation therapy (ART) compared to five treatments with standard stereotactic ablative body radiotherapy (SABR) in patients with prostate cancer that has not spread to other parts of the body (localized). ART is a type of radiation therapy that uses information gathered during the treatment cycle to inform, guide, and alter future radiation treatments with respect to location and dose. It may be able to deliver radiation to the site of disease over a shorter time and with smaller margins (less treatment delivered to nearby healthy tissues). SABR is a type of external radiation therapy that uses special equipment to position a patient and precisely deliver radiation to tumors in the body (except the brain). The total dose of radiation is divided into smaller doses given over several days. This type of radiation therapy helps spare normal tissue. Shorter duration near margin-less ART may be just as effective at treating patients with localized prostate cancer but have less quality of life side effects than standard SABR.

Evaluating In Home Cancer Therapy Versus In Clinic Cancer Therapy in Black Men With Locally Advanced, Biochemically Recurrent and Metastatic Prostate Cancer
This phase II trial evaluates the impact of cancer therapy in the patients' home compared to in the clinic on safety, side effects, patient preference, and satisfaction in Black men with prostate cancer that has spread to nearby tissue or lymph nodes (locally advanced), that has increasing prostate-specific antigen after treatment (biochemically recurrent) or that has spread from where it first started (primary site) to other places in the body (metastatic). Typically drug-related cancer care is conducted at a medical center which causes patients to have to spend considerable time away from family, friends, and familiar surroundings. This separation may add to the physical, emotional, social, and financial burden for patients and their families during this difficult time in their lives. Therapy administered to a patient in the patients' residence in the comfort of familiar surrounding using Cancer Connected Access and Remote Expertise (CARE) Beyond Walls (CCBW) may help reduce psychological and financial distress, increase access to care and improve treatment compliance. Giving cancer therapy in the home compared in the clinic may be safe, tolerable and improve patient satisfaction with overall cancer care in Black men with locally advanced, biochemically recurrent or metastatic prostate cancer.

Abiraterone and Prednisone or Darolutamide for the Treatment of Advanced Prostate Cancer
This phase II trial compares the effects, good and/or bad of abiraterone and prednisone or darolutamide alone in treating patients with prostate cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Androgens (male hormones) can cause the growth of prostate tumor cells. Abiraterone acetate lowers the amount of androgens made by the body. This may help stop the growth of prostate tumor cells that need androgen to grow. Darolutamide blocks the use of androgens by the tumor cells. Prednisone is used to lessen inflammation and lower the body's immune response. Researchers want to compare the side effects of standard of care (SOC) abiraterone and prednisone or darolutamide alone in treating patients with advanced 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.

REVELUTION-2: Relugolix+Abiraterone Acetate (AA) Versus Leuprolide+AA Cardiac Trial
This phase III/IV trial compares the impact of leuprolide and abiraterone acetate (AA) versus relugolix and AA on the heart in hormone-naive patients with advanced prostate cancer receiving pelvic radiation therapy. Leuprolide is in a class of medications called gonadotropin-releasing hormone agonists (GNRHa). It prevents the body from making luteinizing hormone-releasing hormone (LHRH) and luteinizing hormone (LH). This causes the testicles to stop making testosterone (a male hormone) in men and may stop the growth of prostate tumor cells that need testosterone to grow. Abiraterone acetate, an androgen biosynthesis inhibitor, works by decreasing the amount of certain hormones in the body. Relugolix, a GNRH antagonist, works by decreasing the amount of testosterone produced by the body. This may slow or stop the spread of prostate tumor cells that need testosterone to grow. The use of hormone therapy with radiation therapy has been shown to improve survival, however, studies have suggested that the addition of hormone therapy may worsen heart (cardiac) disease and high blood pressure. In fact, studies have shown that the most common cause of death in prostate cancer patients is due to heart disease or heart attacks. Computed tomography (CT) scans create a series of detailed pictures of areas inside the body; the pictures are created by a computer linked to an x-ray machine. In this study, sophisticated cardiac CT images are used to take pictures of patients' heart and coronary arteries to help assess damage to the heart. Using cardiac CT and blood tests, this trial may help doctors determine which patients are at risk of cardiac disease when treated with combination hormone therapy, as well as the differential risk of leuprolide versus relugolix in combination with abiraterone acetate.

Proton Radiation Therapy for the Treatment of Patients With High Risk Prostate Cancer
This phase II trial investigates whether proton radiation therapy directed to the prostate tumor, pelvic, and para-aortic lymph nodes, is an effective way to treat patients with high-risk or lymph node positive prostate cancer who are receiving radiation therapy, and if it will result in fewer gastrointestinal and genitourinary side effects. Proton beam therapy is a new type of radiotherapy that directs multiple beams of protons (positively charged subatomic particles) at the tumor target, where they deposit the bulk of their energy with essentially no residual radiation beyond the tumor. By reducing the exposure of the healthy tissues and organs to radiation in the treatment of prostate cancer, proton therapy has the potential to better spare healthy tissue and reduce the side effects of radiation therapy.

RElugolix VErsus LeUprolide Cardiac Trial
This clinical trial investigates the impact of prostate cancer treatment, specifically androgen deprivation therapy (ADT), on the heart and coronary vessels among men with localized, non-metastatic prostate cancer undergoing definitive radiation therapy and concomitant ADT. Recently, cardiovascular toxicity from hormone therapy that is routinely used for prostate cancer (e.g. leuprolide) has emerged as a concern, yet studies identifying who is at risk and the mechanism of cardiac damage are lacking. Additionally, a new hormone therapy drug, relugolix, has recently been Food and Drug Administration (FDA)-approved and may reduce toxicity to the heart. This trial intends to investigate the mechanism of cardiovascular toxicity from ADT, investigate the mechanism by which relugolix reduces cardiovascular toxicity, and identify predictive biomarkers to improve individualized risk-assessment for cardiovascular toxicity from ADT.
