Docetaxel, Carboplatin, and Rucaparib Camsylate in Treating Patients With Metastatic Castration Resistant Prostate Cancer With Homologous Recombination DNA Repair Deficiency
This phase II trial studies how well docetaxel with carboplatin followed by rucaparib camsylate works in treating patients with metastatic castration resistant prostate cancer (spread outside of prostate and resistant to testosterone suppression) with homologous recombination DNA repair deficiency. Chemotherapy drugs, such as docetaxel and carboplatin, work to stop the growth of cancer cells, by stopping them from dividing or spreading. Rucaparib camsylate may stop the growth of tumor cells with defects in the ability to repair mistakes in DNA by forcing additional errors so that the cancer cells cannot overcome the number of errors and will then die. Giving induction docetaxel and carboplatin followed by maintenance rucaparib camsylate may work better in treating patients with castration resistant prostate cancer.

PSCA-Targeting CAR-T Cells Plus or Minus Radiation for the Treatment of Patients With PSCA+ Metastatic Castration-Resistant Prostate Cancer
This phase Ib trial tests the safety, side effects, and best dose of autologous anti-prostate stem cell antigen (PSCA)-chimeric antigen receptor (CAR)-4-1BB/TCRzeta-CD19t-expressing T-lymphocytes (PSCA-CAR T cells), plus or minus radiation, 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). Castration-resistant prostate cancer continues to grow and spread despite the surgical removal of the testes or medical intervention to block androgen production. CAR T-cell therapy is a type of treatment in which a patient's T cells (a type of immune system cell) are changed in the laboratory so they will attack cancer 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 cancer 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. Radiation therapy uses high energy x-rays to kill cancer cells and shrink tumors. Giving PSCA-targeting CAR T-cells, with or without radiation, may kill more tumor cells in men with castration-resistant prostate cancer.

Schedule De-Escalation of 177Lu-PSMA-617 for the Treatment of Metastatic Castrate Resistant Prostate Cancer
This phase II trial studies how to improve the usage of Lu 177 vipivotide tetraxetan (177Lu-prostate-specific membrane antigen \[PSMA\]-617) for treating patients with castration-resistant prostate cancer that has spread from where it first started (primary site), to other places in the body (metastatic) utilizing a treatment pause after 5 cycles of therapy versus standard continuous treatment for 6 cycles. Lutetium is a radioligand therapy (RLT). RLT uses a small molecule (in this case 177Lu-PSMA-617) that carries a radioactive component to destroy tumor cells. When lutetium is injected into the body, it attaches to the PSMA receptor found on tumor cells. After lutetium attaches to the PSMA receptor, its radiation component destroys the tumor cell. Giving 177Lu-PSMA-617 for 5 cycles versus 6 cycles may better treat patients with metastatic castrate resistant prostate cancer.

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.

Impact of DNA Repair Pathway Alterations on Sensitivity to Radium-223 in Bone Metastatic Castration-resistant Prostate Cancer
This study investigates how well radium-223 works in treating patients with castration-resistant prostate cancer than has spread to the bones (bone metastases). Prostate cancer is the most common cancer in men and the second leading cause of cancer death. Furthermore, many men with notably advanced disease have been found to have abnormalities in DNA repair. The purpose of this research is to study the role of a DNA repair pathway in prostate cancer, specifically in response to administration of radium-223, an FDA-approved drug known to cause DNA damage to cancerous cells. Understanding how defects in the DNA repair pathway affects radium-223 treatment of prostate, may help doctors help plan effective treatment in future patients.

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.

Abiraterone Acetate and Antiandrogen Therapy With or Without Cabazitaxel and Prednisone in Treating Patients With Metastatic, Castration-Resistant Prostate Cancer Previously Treated With Docetaxel
This randomized phase II trial studies how well abiraterone acetate and antiandrogen therapy, with or without cabazitaxel and prednisone, work in treating patients with castration-resistant prostate cancer previously treated with docetaxel that has spread to other parts of the body. Androgens can cause the growth of prostate cancer cells. Hormone therapy using abiraterone acetate and antiandrogen therapy may fight prostate cancer by lowering and/or blocking the use of androgens by the tumor cells. Drugs used in chemotherapy, such as cabazitaxel and prednisone, 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 abiraterone acetate and antiandrogen therapy with or without cabazitaxel and prednisone may help kill more tumor cells.

Vorinostat and 177Lu-PSMA-617 for the Treatment of PSMA-Low Metastatic Castration-Resistant Prostate Cancer
This phase II trial tests how well vorinostat works in treating patients with prostate-specific membrane antigen (PSMA)-low castration-resistant prostate cancer that has spread from where it first started (primary site) to other places in the body (metastatic) (mCRPC). Prostate cancer that has not spread to other parts of the body (localized) is typically treated through surgery or radiotherapy, which for many men is curable. Despite definitive local therapy, cancer that has come back after a period of improvement (recurrent) disease develops in 27-53% of men. Often this is detected by measurement of prostate-specific antigen (PSA) without visible evidence of metastatic disease. Lutetium Lu 177 vipivotide tetraxetan (177Lu-prostate specific membrane antigen \[PSMA\]-617) is a new small molecule PSMA-targeted radioactive therapy that has been approved by the Food and Drug Administration for the treatment of adult patients with PSMA-positive mCRPC who have been treated with androgen receptor inhibitors and taxane-based chemotherapy. Vorinostat is used to treat various types of cancer that does not get better, gets worse, or comes back during or after treatment with other drugs. Vorinostat is a drug which inhibits the enzyme histone deacetylase and may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving vorinostat and 177Lu-PSMA-617 may kill more tumor cells in in patients with PSMA-low mCRPC.

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

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.

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.

Cabazitaxel, Carboplatin, and Cetrelimab Followed by Niraparib With or Without Cetrelimab for the Treatment of Aggressive Variant Metastatic Prostate Cancer
This phase II trial studies the effect of cabazitaxel, carboplatin, and cetrelimab followed by niraparib with or without cetrelimab in treating patients with aggressive variant prostate cancer that has spread to other places in the body (metastatic). Chemotherapy drugs, such as cabazitaxel and carboplatin, 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. PARPs are proteins that help repair DNA mutations. PARP inhibitors, such as niraparib, can keep PARP from working, so tumor cells can't repair themselves, and they may stop growing. Immunotherapy with monoclonal antibodies, such as cetrelimab, may help the body's immune system attack the tumor, and may interfere with the ability of tumor cells to grow and spread. Giving niraparib with or without cetrelimab, after treatment with cabazitaxel, carboplatin, and cetrelimab, may help control aggressive variant prostate cancer.
