Testing the Safety of Different Doses of Olaparib Given Radium-223 for Men With Advanced Prostate Cancer With Bone Metastasis

This phase I/II trial studies the best dose and side effects of olaparib and how well it works with radium Ra 223 dichloride in treating patients with castration-resistant prostate cancer that has spread to the bone and other places in the body (metastatic). PARPs are proteins that help repair DNA mutations. PARP inhibitors, such as olaparib, can keep PARP from working, so tumor cells can't repair themselves, and they may stop growing. Radioactive drugs, such as radium Ra 223 dichloride, may carry radiation directly to tumor cells and not harm normal cells. Giving olaparib and radium Ra 223 dichloride may help treat patients with castration-resistant prostate cancer.

Testing the Effectiveness of Two Immunotherapy Drugs (Nivolumab and Ipilimumab) With One Anti-cancer Targeted Drug (Cabozantinib) for Rare Genitourinary Tumors

This phase II trial studies how well cabozantinib works in combination with nivolumab and ipilimumab in treating patients with rare genitourinary (GU) tumors that has spread from where it first started (primary site) to other places in the body. 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 and ipilimumab, 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, nivolumab, and ipilimumab may work better in treating patients with genitourinary tumors that have no treatment options compared to giving cabozantinib, nivolumab, or ipilimumab alone.

Abemaciclib Before 177Lu-PSMA-617 for the Treatment of Metastatic Castrate Resistant Prostate Cancer

This phase I/II trial tests the safety, side effects, and best dose of abemaciclib and whether it works before 177Lu-PSMA-617 in treating patients with castration resistant prostate cancer that has spread to other places in the body (metastatic). Abemaciclib is in a class of medications called kinase inhibitors. It is highly selective inhibitors of cyclin-dependent kinase 4 and 6, which are proteins involved in cell differentiation and growth. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. Radioligand therapy uses a small molecule (in this case 177Lu-PSMA-617), which carries a radioactive component to destroys tumor cells. When 177Lu-PSMA-617 is injected into the body, it attaches to the prostate-specific membrane antigen (PSMA) receptor found on tumor cells. After 177Lu-PSMA-617 attaches to the PSMA receptor, its radiation component destroys the tumor cell. Giving abemaciclib before 177Lu-PSMA-617 may help 177Lu-PSMA-617 kill more tumor cells.

ZEN-3694, Enzalutamide, and Pembrolizumab for the Treatment of Metastatic Castration-Resistant Prostate Cancer

This phase II trial investigates how well ZEN-3694, enzalutamide, and pembrolizumab work in treating patients with castration-resistant prostate cancer that has spread to other places in the body (metastatic). ZEN-3694 blocks the expression of the MYC gene to prevent cellular growth in certain types of tumors, including castrate resistant prostate cancer. Enzalutamide has been shown to block testosterone from reaching prostate cancer cells by binding to a receptor on prostate cancer cells, called androgen receptors. This works similar to a lock and key. When enzalutamide (key) inserts into the androgen receptor (lock) testosterone cannot attach to the androgen receptor, which slows the growth of tumor cells and may cause them to shrink. Pembrolizumab is a monoclonal antibody (proteins that can protect the body from foreign organisms, such as bacteria and viruses) designed to block a specific control switch which may be activated by tumor cells to overcome the body's natural immune system defenses. It also enhances the activity of the body's immune cells against tumor cells. The purpose of this study is to find out the effects ZEN-3694, enzalutamide, and pembrolizumab on patients with metastatic castration-resistant prostate cancer who have previously experienced disease progression.

CJNJ-67652000 and Prednisone for Treatment of Metastatic Castration-Resistant Prostate Cancer and SPOP Gene Mutations

This phase II trial tests how well abiraterone acetate/niraparib (CJNJ-67652000 \[niraparib/abiraterone acetate fixed-dose combination\]) and prednisone works in treating patients with castration-resistant prostate cancer that has spread from where it first started (primary site) to other places in the body (metastatic) and who have a mutation in the SPOP gene. CJNJ-67652000 (niraparib/abiraterone acetate fixed-dose combination) is a drug which stops certain cancer cells from being able to repair themselves from damage, leading to the death of the cancer cell. 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 CJNJ-67652000 and prednisone may kill more tumor cells in patients with metastatic prostate cancer than giving these drugs alone.

Supraphysiological Androgen to Enhance Treatment Activity in Metastatic Castration-Resistant Prostate Cancer, SPECTRA Study

This phase II trial studies how well giving testosterone at levels higher than normally found in the body (supraphysiological) works to enhance chemotherapy treatment, and Lutetium 177Lu-prostate specific-membrane antigen (PSMA)-617 (LuPSMA) in patients with prostate cancer that has progressed despite being previously treated with androgen therapies and has spread from where it first started (prostate) to other places in the body (metastatic castration-resistant prostate cancer). In patients that have developed progressive cancer in spite of standard hormonal treatment, administering supraphysiological testosterone may result in regression of tumors by causing deoxyribonucleic acid (DNA) damage in tumor cells that have adapted to low testosterone conditions. Carboplatin is in a class of medications known as platinum-containing compounds. Carboplatin works by killing, stopping or slowing the growth of tumor cells. Etoposide is in a class of medications known as podophyllotoxin derivatives. It blocks a certain enzyme needed for cell division and DNA repair and may kill tumor cells. Radioactive drugs, such as LuPSMA, may carry radiation directly to tumor cells and not harm normal cells. Giving supraphysiological levels of testosterone and carboplatin or etoposide or LuPSMA together may be an effective treatment for metastatic castration-resistant prostate cancer.

Extremely Hypofractionated Intensity Modulated Stereotactic Body Radiotherapy for the Treatment of Prostate Cancer With Rising PSA After Radical Prostatectomy

This phase II trial investigates the effect of extremely hypofractionated intensity modulated stereotactic body radiotherapy in treating patients with prostate cancer that has rising prostate specific antigen (PSA) after radical prostatectomy. Stereotactic body radiation therapy 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 and cause less damage to normal tissue. 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.

Advanced ChemoHormonal Therapy for Treatment Naive Metastatic Prostate Cancer

This phase II trial studies how well the combination of apalutamide, abiraterone acetate, and prednisone after chemotherapy work in treating patients that have received no prior treatment (treatment naive) for high risk prostate cancer that is sensitive to androgen deprivation therapy (castration sensitive) and has spread to other parts of the body (metastatic). This study also aims to understand the inheritance of prostate cancer. If a gene or genes that cause prostate cancer can be found, the diagnosis and treatment of prostate cancer may be improved. Testosterone (a male hormone) can cause the growth of prostate cancer cells. Hormone therapy using apalutamide may fight prostate cancer by blocking the use of testosterone by the tumor cells. Antihormone therapy, such as abiraterone acetate, may lessen the amount of testosterone made by the body. Anti-inflammatory drugs such as prednisone lower the body's immune response and are used with other drugs in the treatment of some types of cancer. Apalutamide, abiraterone acetate, and prednisone after chemotherapy may work better in treating patients with castration sensitive prostate cancer.

Testing the Safety and Effectiveness of Radiation-based Treatment (Lutetium Lu 177 Dotatate) for Metastatic Prostate Cancer That Has Neuroendocrine Cells

This phase II trial studies how well lutetium Lu 177 dotatate works in treating patients with prostate cancer with neuroendocrine differentiation that has spread to other places in the body (metastatic). Neuroendocrine differentiation refers to cells that have traits of both hormone-producing endocrine cells and nerve cells. These cells release hormones into the blood in response to a signal from the nervous system. Hormones are biological substances that circulate through the bloodstream to control the activity of other organs or cells in the body. Lutetium Lu 177-dotatate is a radioactive drug. It binds to a protein called somatostatin receptor, which is found on some neuroendocrine tumor cells. Lutetium Lu 177-dotatate builds up in these cells and gives off radiation that may kill them. It is a type of radioconjugate and a type of somatostatin analog. Treatment with Lutetium Lu 177 dotatate may shrink the tumor in a way that can be measured in patients with metastatic prostate cancer with neuroendocrine differentiation.

Low PSMA SUV Boost (LPS-Boost): Intensified 177Lu-PSMA-617 Treatment for Patients With Metastatic Castrate-Resistant Prostate Cancer With Low PSMA Expressing Disease

This phase II trial tests how well 177Lu-PSMA-617 works in treating patients with prostate cancer that has spread from where it first started (primary site) to other places in the body (metastatic) and that remains despite treatment (resistant). Lutetium Lu 177 (177Lu), the radioactive (tracer) component being delivered by prostate-specific membrane antigen (PSMA)-617, has physical properties that make it ideal radionuclide (imaging tests that uses a small dose tracer) for treatment of metastatic castrate-resistant prostate cancer (mCRPC). 177Lu-PSMA-617 works by binding to prostate cancer cells and inducing damage to deoxyribonucleic acid (DNA) inside prostate cancer cells. Giving 177Lu-PSMA-617 may improve treatment outcomes for patients with mCRPC.

Testing Different Dosing Schedules of the Anti-cancer Drug, Lutetium 177Lu PSMA RLT and Its Effect on Patients With Advanced Prostate Cancer, RECIPROCAL Trial

This randomized phase III trial examines whether lengthening the dosage interval in an adaptive manner for the prostate cancer drug lutetium 177 Lu PSMA RLT improves quality of life without decreasing lifespan when compared to the standard way this medication is given. This study is for patients with hormone resistant prostate cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body. Hormone resistant prostate cancer often has many cells containing a protein called prostate-specific membrane antigen (PSMA) on their surface. The normal cells in the prostate do not normally express as much PSMA protein on their surface as cancer cells. Lutetium 177 Lu PSMA RLT binds to the PSMA protein on the tumor cells. It builds up in these cells and gives off radiation that may kill them. Typically, this medication is given at the same dose every 6 weeks for up to 6 doses. In this trial, researchers want to see if treatment following the first two doses of lutetium 177 Lu PSMA RLT can be delayed until there is evidence of disease activity. This may be an effective way to improve quality of life without decreasing lifespan in patients with advanced prostate cancer.

Testing the Addition of Docetaxel (Chemotherapy) to the Usual Treatment (Hormonal Therapy and Apalutamide) for Metastatic Prostate Cancer, ASPIRE Trial

This phase III trial compares the effect of adding docetaxel to hormonal therapy and apalutamide versus hormonal therapy and apalutamide alone in treating patients with prostate cancer that has spread from where it first started (primary site) to other places in the body (metastatic). Docetaxel is in a class of medications called taxanes. It stops tumor cells from growing and dividing and may kill them. Hormone therapy for prostate cancer, also called androgen deprivation therapy (ADT), uses surgery or drugs to lower the levels of male sex hormones in a man's body. This helps slow the growth of prostate cancer. 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 tumor cells. Giving docetaxel in addition to the usual treatment of hormonal therapy and apalutamide may work better in treating patients with metastatic prostate cancer than the usual treatment alone.

Cell Therapy (STEAP1 CART) With Enzalutamide for the Treatment of Patients With Metastatic Castration-Resistant Prostate Cancer

This phase I/II trial tests the safety and effectiveness of cell therapy (STEAP1 CART) with enzalutamide in treating patients with prostate cancer that continues to grow despite surgical or medical treatments to block androgen production (castration-resistant) and that has spread from where it first started (the prostate) to other places in the body (metastatic). Prostate cancer is the second leading cause of cancer deaths in men. Localized prostate cancer is often curable and even metastatic disease may respond to treatment for a few years. Despite multiple therapies, including hormone therapy and chemotherapy, metastatic castration-resistant prostate cancer (mCRPC) remains an incurable disease. Recently, adoptive cellular immunotherapies have been developed to transfer immunogenic cells to the patient to produce an anti-tumor response. Chimeric antigen receptor T (CART)-cell therapy is a type of treatment in which a patient's T-cells (a type of immune cell) are changed in the laboratory so they will attack tumor cells. T cells are taken from a patient's blood. Then the gene for a special receptor that binds to a certain protein on the patient's tumor cells is added to the T cells in the laboratory. The special receptor is called a chimeric antigen receptor (CAR). Large numbers of the CAR T cells are grown in the laboratory and given to the patient by infusion for treatment of certain cancers. Prostate stem cell antigen and prostate specific membrane antigen CAR T cell therapies have been shown to be safe and effective, but objective tumor responses remain rare. STEAP1 is an antigen that promotes cancer growth and spread and is found to be broadly expressed in mCRPC tissues. STEAP1 CART is CAR T cells that have been engineered with a STEAP1 antigen to better target prostate tumor cells. Enzalutamide 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 STEAP1 CART with enzalutamide may kill more tumor cells in patients with mCRPC.

Testing the Addition of the Drug Relugolix to the Usual Radiation Therapy for Advanced-Stage Prostate Cancer, The NRG Promethean Study

This phase II trial compares the usual treatment of radiation therapy alone to using the study drug, relugolix, plus the usual radiation therapy in patients with castration-sensitive prostate cancer that has spread to limited other parts of the body (oligometastatic). Relugolix is in a class of medications called gonadotropin-releasing hormone (GnRH) receptor antagonists. It works by decreasing the amount of testosterone (a male hormone) produced by the body. It may stop the growth of cancer cells that need testosterone to grow. Radiation therapy uses high-energy x rays or protons to kill tumor cells. The addition of relugolix to the radiation may reduce the chance of oligometastatic prostate cancer spreading further.

This phase I/II trial studies the best dose of M3814 when given together with radium-223 dichloride or with radium-223 dichloride and avelumab and to see how well they work in treating patients with castrate-resistant prostate cancer that had spread to other places in the body (metastatic). M3814 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radioactive drugs, such as radium-223 dichloride, may carry radiation directly to tumor cells and not harm normal cells. Immunotherapy with monoclonal antibodies, such as avelumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. This study is being done to find out the better treatment between radium-223 dichloride alone, radium-223 dichloride in combination with M3814, or radium-223 dichloride in combination with both M3814 and avelumab, to lower the chance of prostate cancer growing or spreading in the bone, and if this approach is better or worse than the usual approach for advanced prostate cancer not responsive to hormonal therapy.

Treating Prostate Cancer That Has Come Back After Surgery With Apalutamide and Targeted Radiation Based on PET Imaging

This phase III trial tests two questions by two separate comparisons of therapies. The first question is whether enhanced therapy (apalutamide in combination with abiraterone + prednisone) added to standard of care (prostate radiation therapy and short term androgen deprivation) is more effective compared to standard of care alone in patients with prostate cancer who experience biochemical recurrence (a rise in the blood level of prostate specific antigen \[PSA\] after surgical removal of the prostate cancer). A second question tests treatment in patients with biochemical recurrence who show prostate cancer spreading outside the pelvis (metastasis) by positron emission tomography (PET) imaging. In these patients, the benefit of adding metastasis-directed radiation to enhanced therapy (apalutamide in combination with abiraterone + prednisone) is tested. Diagnostic procedures, such as PET, may help doctors look for cancer that has spread to the pelvis. Androgens are hormones that may cause the growth of prostate cancer cells. Apalutamide may help fight prostate cancer by blocking the use of androgens by the tumor cells. Metastasis-directed targeted radiation therapy uses high energy rays to kill tumor cells and shrink tumors that have spread. This trial may help doctors determine if using PET results to deliver more tailored treatment (i.e., adding apalutamide, with or without targeted radiation therapy, to standard of care treatment) works better than standard of care treatment alone in patients with biochemical recurrence of prostate cancer.

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.

Bipolar Androgen Therapy to Restore Sensitivity to Androgen Deprivation Therapy for Patients With Metastatic Castration Resistant Prostate Cancer

This phase I trial tests the change in androgen receptor sensitivity, side effects and effectiveness of bipolar androgen therapy, using testosterone, in patients with castration resistant prostate cancer that has spread to other places is the body (metastatic). Bipolar androgen therapy is the regulation of testosterone between castration levels (lower than what would be normally present) and supraphysiological levels (amounts greater than normally found in the body). This may suppress cancer cell growth, which reduces prostate-specific antigen (PSA) levels and may delay cancer progression.

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.

Targeted Treatment for Metastatic Prostate Cancer, The PREDICT Trial

This phase II trial evaluates whether genetic testing in prostate cancer is helpful in deciding which study treatment patients are assigned. Patient cancer tissue samples are obtained from a previous surgery or biopsy procedure and tested for deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) abnormalities or mutations in their cancer. Valemetostat tosylate is in a class of medications called EZH1/EZH2 inhibitors. It blocks proteins called EZH1 and EZH2, which may help slow or stop the spread of tumor cells. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of tumor cells. Cabazitaxel injection is in a class of medications called microtubule inhibitors. It works by slowing or stopping the growth of tumor cells. Abiraterone acetate blocks tissues from making androgens (male hormones), such as testosterone. This may cause the death of tumor cells that need androgens to grow. It is a type of anti-androgen. Enzalutamide 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 tumor cells. Lutetium Lu 177 vipivotide tetraxetan is in a class of medications called radiopharmaceuticals. It works by targeting and delivering radiation directly to tumor cells which damages and kills these cells. Assigning patients to targeted treatment based on genetic testing may help shrink or slow the cancer from growing
