Autologous T Cells Lentivirally Transduced to Express L1CAM-Specific Chimeric Antigen Receptors in Treating Patients With Locally Advanced and Unresectable or Metastatic Small Cell Neuroendocrine Prostate Cancer
Description

This phase I trial studies the side effects and best dose of autologous CD8+ and CD4+ lentivirally transduced to express L1CAM-specific chimeric antigen receptor (CAR) and EGFRt mutation specific T cells and to see how well they work in treating patients with small cell neuroendocrine prostate cancer (SCNPC) that has spread to nearby tissue or lymph nodes (locally advanced) and cannot be removed by surgery (unresectable) or has spread from where it first started (primary site) to other places in the body (metastatic). 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 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. Some solid tumor cells have an L1CAM protein on their surface, and T cells can be modified with a receptor, called a chimeric antigen receptor (CAR), to help recognize this protein and kill these tumor cells. Large numbers of the CAR T cells are grown in the laboratory and given to the patient by infusion for treatment of certain cancers. These L1CAM mutation specific T cells may help the body's immune system identify and kill L1CAM locally advanced and unresectable or metastatic small cell neuroendocrine prostate cancers' tumor cells.

Apalutamide Plus Cetrelimab in Patients With Treatment-Emergent Small Cell Neuroendocrine Prostate Cancer
Description

Despite the low androgen receptor (AR) transcriptional activity of treatment-emergent small cell neuroendocrine prostate cancer, there is persistent AR expression observed in the majority of treatment-emergent small-cell neuroendocrine prostate cancer (t-SCNC) biopsies. This indicates that epigenetic dysregulation leads to reprogramming away from an AR-driven transcriptional program. Therefore, continuation of AR blockade in the form of apalutamide may provide additive benefit compared to immune checkpoint blockade alone. The investigators hypothesize that the combination of apalutamide plus cetrelimab will achieve a clinically significant composite response rate with sufficient durability of response in mCRPC patients with evidence of treatment-emergent small cell neuroendocrine prostate cancer

Description

Background: Small cell lung cancer and PARP inhibitor resistant tumors are aggressive cancers. Current treatments for people with these tumors yield little benefit. Researchers want to see if a combination of drugs can help. Objective: To find a safe combination of sacituzumab govitecan and berzosertib and to see if this will cause small cell lung cancer and PARP inhibitor resistant tumors to shrink. Eligibility: People ages 18 and older with a solid tumor, small cell lung cancer, or a homologous recombination-deficient cancer that is resistant to PARP inhibitors Design: Participants will be screened with: Standard clinical exams and tests EKG to test the heart Medical documentation to confirm cancer diagnosis Participants will get sacituzumab govitecan by vein on days 1 and 8 of each 21-day cycle. They will get berzosertib by vein on days 2 and 9. Treatment will continue as long as they can tolerate the drugs and their tumors are either stable or getting better. Before treatment and at least once per cycle, participants will have a physical exam and blood tests. Before treatment and every 2 or 3 cycles, they will have a CT scan. They will have a contrast agent injected into a vein for the scan. Participants will give blood and hair samples and tumor biopsies for research. Biopsies will be taken with a small needle under imaging guidance. After they stop treatment, participants will have a visit 1 month later. They will then be contacted by phone or email every 3 months for the rest of their lives.

Pembrolizumab with Combination Chemotherapy in Treating Participants with Locally Advanced or Metastatic Small Cell/Neuroendocrine Cancers of Urothelium or Prostate
Description

This phase Ib trial studies how well pembrolizumab works with combination chemotherapy in treating participants with small cell/neuroendocrine cancers of the urothelium or prostate that has spread to nearby tissue or lymph nodes or that has spread to other places in the body. Monoclonal antibodies, such as pembrolizumab, may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as etoposide, docetaxel, cisplatin, 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. Giving pembrolizumab with platinum-based chemotherapy may work better in treating participants with small cell/neuroendocrine cancers of the urothelium or prostate.

Randomized Trial of Topotecan With M6620, an ATR Kinase Inhibitor, in Small Cell Lung Cancers and Small Cell Cancers Outside of the Lungs
Description

This phase II trial studies how well berzosertib (M6620) works when given in combination with topotecan hydrochloride (topotecan) compared with topotecan alone in treating patients with small cell lung cancer that has come back (relapsed), or small cell cancer that arises from a site other than the lung (extrapulmonary). Drugs used in chemotherapy, such as topotecan hydrochloride, work by damaging the DNA (deoxyribonucleic acid) in tumor cells, causing those cells to die and the tumor to shrink. However, some tumor cells can become less affected by chemotherapy because they have ways to repair the damaged DNA. The addition of M6620 could help topotecan hydrochloride shrink the cancer and prevent it from returning by blocking enzymes needed for DNA repair.

Cabozantinib S-malate and Nivolumab With or Without Ipilimumab in Treating Patients With Metastatic Genitourinary Tumors
Description

This phase I trial studies the side effects and best doses of cabozantinib s-malate and nivolumab with or without ipilimumab in treating patients with genitourinary (genital and urinary organ) tumors that have spread from where it first started (primary site) to other places in the body (metastatic). Cabozantinib s-malate 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. It is not yet known whether giving cabozantinib s-malate and nivolumab alone or with ipilimumab works better in treating patients with genitourinary tumors.

At-Home Cancer Directed Therapy Versus in Clinic for the Treatment of Patients with Advanced Cancer
Description

This clinical trial studies the effect of cancer directed therapy given at-home versus in the clinic for patients with cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Currently most drug-related cancer care is conducted in infusion centers or specialty hospitals, where patients spend many hours a day isolated from family, friends, and familiar surroundings. This separation adds to the physical, emotional, social, and financial burden for patients and their families. The logistics and costs of navigating cancer treatments have become a principal contributor to patients' reduced quality of life. It is therefore important to reduce the burden of cancer in the lives of patients and their caregivers, and a vital aspect of this involves moving beyond traditional hospital and clinic-based care and evaluate innovative care delivery models with virtual capabilities. Providing cancer treatment at-home, versus in the clinic, may help reduce psychological and financial distress and increase treatment compliance, especially for marginalized patients and communities.

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

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.

Erdafitinib for the Treatment of Patients With Castration-Resistant Prostate Cancer
Description

This phase II trial studies the effect of erdafitinib in treating patients with prostate cancer that grows and continues to spread despite the surgical removal of the testes or drugs to block androgen production (castration-resistant). Erdafitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving erdafitinib may help control disease in patients with castration-resistant prostate cancer. In addition, studying samples of blood, tissue, plasma, and bone marrow from patients with castration-resistant prostate cancer in the laboratory may help doctors learn more about changes that occur in deoxyribonucleic acid (DNA) and identify biomarkers related to cancer.

Olaparib (LYNPARZA) Plus Durvalumab (IMFINZI) in EGFR-Mutated Adenocarcinomas That Transform to Small Cell Lung Cancer (SCLC) and Other Neuroendocrine Tumors
Description

Background: Lung cancers with epidermal growth factor receptor (EGFR) mutations may develop resistance to therapies targeting this protein by evolving/being transformed into small cell or neuroendocrine cancers. There are no standard treatments for it. Researchers want to see if a new combination of drugs can help. Objective: To see if the combination of durvalumab and olaparib will cause tumors to shrink. Eligibility: Adults age 18 and older who had EGFR-mutated non-small-cell lung carcinoma (NSCLC) that was treated and now transformed to SCLC or another neuroendocrine tumor. Design: Participants will be screened under a separate protocol. They may have a tumor biopsy. Participants will have a physical exam. They will have a review of their symptoms, their medicines, and their ability to do their normal activities. They will have blood tests. They will have an electrocardiogram to evaluate their heart. Participants will have a computed tomography (CT) scan, a series of x-rays taken of parts of the body. Participants will get durvalumab on Day 1 of each 28-day cycle. It is given through a small plastic tube that is put in an arm vein. They will take olaparib by mouth twice every day. They will keep a medicine diary. Participants will take the study drugs until their disease gets worse or they have unacceptable side effects. About 30 days after they stop taking the study drugs, participants will have a follow-up visit. Then they will be contacted every 6 months for the rest of their life....

Testing the Combination of XL184 (Cabozantinib), Nivolumab, and Ipilimumab for Poorly Differentiated Neuroendocrine Tumors
Description

This phase II trial studies how well the combination of XL184 (cabozantinib), nivolumab, and ipilimumab work in treating patients with poorly differentiated neuroendocrine tumors (i.e., neuroendocrine tumor that does not look like the normal tissue it arose from). 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 shrink the cancer.

Antiandrogen Therapy, Abiraterone Acetate, and Prednisone With or Without Neutron Radiation Therapy in Treating Patients With Prostate Cancer
Description

This phase II trial studies how well antiandrogen therapy, abiraterone acetate, and prednisone with or without neutron radiation therapy work in treating patients with prostate cancer. Hormone therapy such as antiandrogen therapy may fight prostate cancer by blocking the production and interfering with the action of hormones. Abiraterone acetate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as 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. Neutron radiation therapy uses high energy neutrons to kill tumor cells and shrink tumors. It is not yet known whether antiandrogen therapy, abiraterone acetate, and prednisone with or without neutron radiation therapy may work better in treating patients with prostate cancer.

Lurbinectedin With or Without Avelumab in Small Cell Carcinoma of the Bladder (LASER)
Description

Background: Small cell carcinoma of the bladder (SCCB) and other high-grade neuroendocrine tumors (HGNET) of the urinary tract are rare but aggressive cancers. Average survival for people diagnosed with SCCB or HGNET is about 1 year. Lurbinectedin and avelumab are drugs that are approved to treat other cancers. Researchers want to see if these drugs can help people with SCCB or HGNET. Objective: To test lurbinectedin with or without avelumab in people with SCCB or HGNET. Eligibility: Adults aged 18 years and older with SCBB or HGNET that returned and spread after treatment. Design: Participants will be screened. They will have a physical exam. They will have blood tests and imaging scans. They may need to have a new biopsy: A small needle will be used to collect a tissue sample from the tumor. Both study drugs are given through a tube attached to a needle inserted into a vein. If participants have already received a drug like avelumab they will receive only lurbinectedin. If patients have not been previously treated with a drug like avelumab they will receive both lurbinectedin and avelumab. All participants will receive their treatment once every 3 weeks for up to 10 years. They will also receive other drugs to relieve adverse effects. Biopsies, blood tests, and imaging scans will be repeated during some study visits. Participants may also have urine tests and tests of their heart function. Participants may remain in the study as long as the treatment is helping them. If they stop treatment, they will have safety visits 14, 30, and 90 days after their last dose. Additional follow-up visits will continue 5 to 10 years.

A Multi-Center Natural History of Urothelial Cancer and Rare Genitourinary Tract Malignancies
Description

Background: Tumors in the genitourinary tracts can occur in the kidney, bladder, prostate, and testicles and can have common and rare histologies. Some cancers that occur along the genitourinary (GU) tract are rare. Some GU tumors are so rare that they are not included in treatment studies or tissue banks. This makes it hard for researchers to determine standards of care. Researchers want to learn more about common and rare GU tumors. Objective: To learn more about urinary tract cancers. Eligibility: People ages 18 and older with urinary tract or GU cancer such as bladder, kidney, testicular, prostate, penis, or neuroendocrine cancer. Design: Participants will be screened with questions about their medical history. Their medical records will be reviewed. Participants will have a physical exam. They will give blood and urine samples. They will complete a survey about their family cancer history. Clinical photographs will be taken to document skin lesions. Participants may have imaging scans of their chest, abdomen, and pelvis. They may have a contrast agent injected into their arm. Participants will get recommendations about how to best manage and treat their cancer. They can ask as many questions as they would like. Participants will provide existing tumor samples if available. They may have optional tumor biopsies up to twice a year. For needle biopsies, the biopsy area will be numbed and they will get a sedative. A needle will be inserted through their skin to collect a tumor sample. For skin biopsies, their skin will be numbed. A small circle of skin will be removed. Some blood and tumor samples may be used for genetic tests. Participants will have frequent follow-up visits.

DAREON™-5: A Study to Test Whether Different Doses of BI 764532 Help People With Small Cell Lung Cancer or Other Neuroendocrine Cancers
Description

This study is open to adults with small cell lung cancer and other neuroendocrine tumours. The study is in people with advanced cancer for whom previous treatment was not successful or no standard treatment exists. The purpose of this study is to find a suitable dose of BI 764532 that people with advanced cancer can tolerate. 2 different doses of BI 764532 are tested in this study. Another purpose is to check whether BI 764532 can make tumours shrink. BI 764532 is an antibody-like molecule (DLL3/CD3 bispecific) that may help the immune system fight cancer. The study has 2 parts. In Part 1, participants are put into 2 groups randomly, which means by chance. Participants have an equal chance of being in either group. One group gets dose 1 of BI 764532 and the other group gets dose 2 of BI 764532. In Part 2, all participants receive the same dose of BI 764532. Part 2 is open to people with a certain kind of tumour called extrapulmonary neuroendocrine carcinoma. All participants receive BI 764532 as an infusion into a vein when starting treatment. If there is benefit for the participants and if they can tolerate it, the treatment is given up to the maximum duration of the study. During this time, participants visit the study site regularly. The total number of visits depends on how they respond to and tolerate the treatment. The first study visits include an overnight stay to monitor participants´ safety. Doctors record any unwanted effects and regularly check the general health of the participants.

[212Pb]VMT-Alpha-NET in Metastatic or Inoperable Somatostatin-Receptor Positive Gastrointestinal Neuroendocrine Tumors, Pheochromocytoma/Paragangliomas, Small Cell Lung, Renal Cell, and Head and Neck Cancers
Description

Background: Some cancers have high levels of proteins called somatostatin receptors (SSTRs) on the surface of the tumors. These tumors can be in the lung, head and neck, digestive tract, kidneys, and in or near the adrenal glands. Researchers want to know if drug treatments that target SSTRs can help shrink these types of tumors. Objective: To test a study drug (\[212Pb\]VMT-Alpha-NET) in people with tumors that have SSTRs. Eligibility: People aged 18 years and older with tumors of the lung, kidneys, head and neck, digestive tract, or adrenal glands that have SSTRs. Their tumors must have spread to other organs and cannot be removed with surgery. Design: Participants will be screened. They will have a physical exam with blood and urine tests. They will have imaging scans and a test of their heart function. A sample of tumor tissue may be collected if one is not already available. \[212Pb\]VMT-Alpha-NET is given through a tube attached to a needle inserted into a vein. The drug will be given on the first day of four 8-week cycles. Participants will stay in the hospital for a few nights after each dose. They will have blood tests once a week during each cycle. Some participants will also get a related study drug (\[203Pb\]VMT-Alpha-NET). They will receive this drug a few days before the first 2 cycles. At 4, 24, and 48 hours after each infusion, they will have whole body scans. These scans will show where the study drug went in their body. Follow-up visits will continue up to 6 years after the last treatment.

Phase I/II Trial of Rhenium 188-P2045 in Small Cell Lung Cancer and Other Advanced Neuroendocrine Carcinomas
Description

There are two parts to this trial. The first study will evaluate increasing doses of Re188 P2045 in patients with advanced small cell lung cancer that has recurred after initial therapy or in patients with other advanced neuroendocrine cancers that have progressed after therapy. Re188 P2045 is designed to attach to type 2 somatostatin receptors that are frequently expressed in those cancers and then the radioactivity from Re188 will kill the cancer cell. Only patients who have cancers that can be seen when Tc99 P2045 is administered (also seeks out the SSTR2, but Tc99 images, but does not treat the cells) will be treated. Therefore, this approach maximizes the possibility that patients will benefit from treatment in that only those who have cancers that have the target will undergo treatment. The primary purpose of this study will be to determine the highest dose of Re188 P2045 that can be safely administered. The second study will open after the conclusion of the first. Patients will first undergo the scan with Tc99 P2045 and then be treated with topotecan for three days. Topotecan is a standard chemotherapy drug that is approved for second line therapy for small cell and frequently used for other neuroendocrine cancers. Following that, patients will then be re-evaluated with the Tc99 P2045 scan and if it demonstrates that the tumor is positive for SSTR2, then patients will receive Re188 P2045. The goal of this study is to determine the highest dose of Re188 P2045 that can be safely administered after topotecan as well as to determine if topotecan will increase the chance that the tumor will express SSTR2.
