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.

A Study of Chemoimmunotherapy for the Treatment of Men With Neuroendocrine or Aggressive Variant Metastatic Prostate Cancer

The purpose of this study is to evaluate the safety and efficacy of a combination of nivolumab, ipilimumab, cabazitaxel and carboplatin in men with neuroendocrine prostate cancer (NEPC) or other aggressive variants of prostate cancer (AVPC). This study will also investigate biomarkers to gain a better understanding of how the drug combination of nivolumab, ipilimumab, cabazitaxel and carboplatin affects these types of prostate cancer and the immune system. Eligible subjects will receive up to 10 cycles of nivolumab, ipilimumab, carboplatin and cabazitaxel followed by maintenance nivolumab and ipilimumab. Subjects may continue receiving study drugs until cancer progression, severe toxicity, withdrawal of consent, 3 years from the initial dose of study drugs or study termination, whichever occurs earlier. Subjects will be followed for 3 years from the initial dose of study drugs.

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.

Pilot Study for Detection of PSMA-Low CRPC-NE Tumors With Fluciclovine PET/CT

This research study is studying a positron emission tomography (PET) agent called 18F-fluciclovine to evaluate how well 18F-fluciclovine-PET scans determine the extent of advanced prostate cancer that either has low prostate-specific membrane antigen (PSMA) expression or has neuroendocrine features. The name of the study interventions are: * 18F-fluciclovine-PET/CT scan * Two research blood collections
