Active clinical trials for "Carcinoma, Neuroendocrine"

This is an open-label，single-arm, phase II exploratory study that evaluates the efficacy and safety of Camrelizumab combined with Chemotherapy （carboplatin or cisplatin + etoposide）and Apatinib as First Line treatment in Advanced or Metastatic Extrapulmonary Neuroendocrine Carcinomas（EP-NEC）

This is the first study to be done in a newly described class of neuroendocrine tumors known as well-differentiated grade 3 neuroendocrine tumors (WD G3 NET). First described in the pancreas in 2017, the classification was broadened to include gastrointestinal tract tumors in 2019. Recent data suggest an equivalent subtype exists in the lungs (NEC with carcinoid morphology). WD G3 NETs can occur de novo as well as the result of grade progression over time. This is a single arm, multi-site, Phase II study in biomarker "unselected" participants. This study will also incorporate serial blood samples, tumor biopsies, and special imaging to better understand the impact of therapy on the tumor and microenvironment. Hyperpolarized (HP) 13C-pyruvate magnetic resonance imaging (MRI) - a novel non-radioactive imaging modality able to provide in vivo measurements of the pyruvate-to-lactate conversion rate (kpl).

Background: Neuroendocrine neoplasms (NENs) are rare cancers in the gastrointestinal tract, pancreas, lungs, adrenal glands, and other areas of the body. Many of these cancers have a high risk of relapse and a low chance of survival. Better treatments are needed. Objective: To test a new drug, ADCT-701, in people with NENs. Eligibility: Adults aged 18 and older with NENs. Design: Participants will be screened. They will have a physical exam with blood and urine tests. They will have imaging scans and tests of heart functioning. Their ability to perform normal daily activities will be tested. A biopsy may be needed: A sample of tissue will be removed from the tumor. ADCT-701 is given through a tube attached to a needle inserted into a vein in the arm. Participants will receive the drug treatment on the first day of 21-day treatment cycles. They will visit the clinic a total of 10 times during the first two cycles. After that, they will visit the clinic 2 times during each cycle. Imaging scans, blood draws, heart function tests, and other tests will be repeated during study visits. Each visit will last up to 8 hours. Participants may continue receiving treatment with the study drug for up to 2 years. After treatment ends, participants will have follow-up clinic visits 4 times in 4 months. They will have a physical exam, with heart and blood tests, at each visit. After that, they will have follow-up clinic visits every 9 weeks; these visits will include imaging scans. Follow-up visits will continue for up to 5 years after treatment began....

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 EGFR 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-EGFRt mutation specific T cells may help the body's immune system identify and kill L1CAM-EGFRt locally advanced and unresectable or metastatic small cell neuroendocrine prostate cancers' tumor cells.

This is a Phase 1/2, open-label, first-in-human (FIH) study designed to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and preliminary antineoplastic activity of TY-1091 administered orally in participants with medullary thyroid cancer (MTC), RET-altered NSCLC and other RET-altered solid tumors.

This study is Phase I/IIa First-in-Human Study of [212Pb]VMT-α-NET Targeted Alpha-Particle Therapy for Advanced SSTR2 Positive Neuroendocrine Tumors

The purpose of the study is to understand the extent and degree of somatostatin receptor expression in poorly differentiated neuroendocrine carcinomas . This may help to make a determination if a radiolabeled somatostatin analog therapy, also referred to as peptide receptor radiotherapy (PRRT), can be a potential alternative in the future. At this time, radiolabeled somatostatin analogs have not been tested in patients with poorly differentiated neuroendocrine carcinomas, and their efficacy in this disease is not well known Understanding the extent and degree of somatostatin receptor expression is important in order to evaluate the potential of radiolabeled somatostatin analog therapy for treatment of poorly differentiated neuroendocrine carcinomas.

Background: - Medullary thyroid cancer (MTC) is a rare cancer of the thyroid gland. In children and adults, it is often part of a condition called Multiple Endocrine Neoplasia 2 (MEN2). MEN2 is usually caused by a genetic mutation, and it can cause a number of problems in addition to MTC. These problems include adrenal gland tumors, hormone changes, and problems with the bones and other organs. Not much is known about how MTC develops over time, especially in people with MEN2. Researchers want to study MTC in children and adults and see how it affects their growth and development. Objectives: - To study how medullary thyroid cancer affects children and adults over time. Eligibility: - Children and adults who have medullary thyroid cancer. Design: Participants will be screened with a brief physical exam and medical history. Blood and tissue samples will be collected to see whether participants have the MEN2 genetic mutation. Treatment will not be provided as part of this study. However, participants will be receiving standard care for MTC. They may be eligible for other clinical trials at the National Institutes of Health. Participants will have regular study visits every 6 to 12 months to evaluate their MTC and any treatment. Blood tests, imaging studies, and other tests may be performed as needed to monitor the disease. Participants and their parents/guardians will also complete questionnaires about their health and emotions during the study.

Neuroendocrine tumors are derived from the neuroendocrine system of the gastroenteropancreatic and bronchopulmonary tract systems. Treatment options include surgery, medical and ablative therapies as well as peptide-receptor radionuclide therapy. Survival is linked to early and accurate diagnoses or to the effective detection of disease recurrence and/or treatment failure. One challenge is to develop accurate non-invasive blood tests that can detect neuroendocrine tumor activity. A second challenge is to evaluate the effectiveness of molecular biomarkers in the natural history of this disease. RegisterNET registry aims at collecting data and blood samples from patients presenting with a NET in the USA. Data will be entered prospectively and anonymized after informed consent. All physicians who treat neuroendocrine tumor patients are invited to participate to the registry. Data will be evaluated within regular time frames, focusing on diagnostic accuracy for biomarkers in the different types and grades of tumors, treatment modalities and patient outcomes (e.g. disease recurrence and survival), thereby contributing to an understanding of the role of biomarkers in tumor management.

With so many therapeutic options available (i.e.: biologic therapy, liver directed therapy, radiotherapy and chemotherapy), the purpose of this project is to partner with patients on comparative effectiveness research (CER) to achieve the goal of alleviating undue toxicity, and optimizing effectiveness and sequencing of therapy for neuroendocrine tumors (NET) patients. We will conduct a study of all newly occurring GEP-NET and lung NET cases aged 18 years and older diagnosed between 01/01/2018 through 12/31/2023 across 14 sites participating in the National Patient-Centered Clinical Research Network (PCORnet), enrolling an average of 215 patients per site over the 3 year study period (~3,000 patients total), allowing up to 60 months of follow-up for medical record outcomes. Participants will complete four online or paper surveys over 18 months; these surveys will focus on patient-reported outcomes, including questions on quality of life, treatment decisions, and experiences with cancer care. Survey data will be linked to participant medical record data to achieve study aims.
