Active clinical trials for "Carcinoma, Neuroendocrine"

Phase II, open-label, multicentre national study. Patients with metastatic neuroendocrine carcinomas of extrapulmonary origin will be eligible. Treatment will be performed as indicated in the section "Investigational drug and reference therapy". Cisplatinum and everolimus dosing is based upon earlier phase 1 studies (Fury et al. 2012). CTs will be done at 9 weekly intervals (after 3 courses of chemotherapy;). Patients will be treated until documented progression according to RECIST 1.1. Enrolment is expected to take between 14 - 16 months. The total study duration is estimated to be 2 to 3 years until publication. Three NET centres in The Netherlands will participate, (Erasmus Medical Center in Rotterdam, Netherlands Cancer Institute in Amsterdam and , the University Medical Center of Groningen) A pre-treatment (and optional post-treatment) tumour biopsy will be included for DNA/RNA analyses and organoid culture. An additional 5cc of blood will be withdrawn as a germline DNA reference. A second 5 cc of blood will be included for measuring circulating tumour transcripts to identify all types of GEP-NET (NETTest).

Currently, there is no standard second line treatment for patients with neuroendocrine carcinoma. Irinotecan monotherapy or combination regimen has shown promising in previous study. The study was designed to confirm thet FOLFIRI regimen can be used as a second-line regimen for patients with advanced or metastatic neuroendocrine carcinoma who have progressed after first-line chemotherapy with platinum based regimen.

This study is designed as Phase II/III. Phase II is aimed to evaluate safety and efficacy of Simmtecan and the 5-FU/LV regimen (FOLFSIM regimen) plus Toripalimab. Phase III is aimed to verify inferiority of the overall survival of FOLFSIM regimen plus Toripalimab in comparison with EP/EC in advanced or metastatic neuroendocrine cancer.

Background: Neuroendocrine neoplasms (NENs) are rare tumors that originate in neuroendocrine cells. NENs can affect almost any part of the body. People with low-grade tumors can live many years. But high-grade tumors can be very aggressive. Researchers want to learn more about this type of cancer. This may help them design better treatments and supportive care studies. Objective: To gain a better understanding of neuroendocrine neoplasms. Eligibility: People starting at age 3 and older who have or are suspected of having NENs and are enrolled in protocol 19C0016, Natural History and Biospecimen Acquisition Study for Children and Adults with Rare Solid Tumors Design: Participants will be screened with questions about their medical history. This may be done over the telephone or in person. Participants medical records, test results, and imaging results will be reviewed. They may have scans and blood tests. They may sign a separate consent form for some of the tests. Participants will complete paper or electronic surveys. The surveys will ask about the effects of cancer on their wellbeing. Participants may give samples of their tumors from previous surgeries or biopsies. These samples will be used to study their tumor genes. Participants will get advice on how to manage their NENs. They will also get recommendations about potential treatment options. Participants home doctors will be contacted every 6 to 12 months. They will give medical data such as imaging and test results. Participants may have follow-up visits at NIH every 6 to 12 months. Participants will contact researchers if there are any changes in their tumor. Participants will be followed on this study for life.

This is phase II study on the efficacy of octreotide lar as maintenance treatment after first-line chemotherapy for patients with unresectable or metastatic gastro-entero-pancreatic or esophageal neuroendocrine carcinomas.

Diarrhea in patients with MTC (Medullary Thyroid Cancer) can be debilitating and, in some cases life threatening. Findings in such patients include volume depletion, renal insufficiency, and electrolyte disorders. Diarrhea can also lead to increased cost of care, reduced quality of life, and treatment delays. Not all patients benefit from conventional anti-diarrheal therapy. CASAD is proven to reduce diarrhea in humans and animals. Clays have water-binding effects, increase the absorptive capacity of the intestinal mucosa, and absorb the excess cytokines which are possible mechanisms of diarrhea in MTC. In this study, we will investigate if starting 1 g CASAD three times a day will ameliorate the severity of diarrhea in patients with MTC. Diarrhea in patients with MTC can be debilitating and, in some cases life threatening. Findings in such patients include volume depletion, renal insufficiency, and electrolyte disorders. We hypothesize that adding CASAD 3 grams/day will reduce the incidence and ameliorate the severity of diarrhea in patients with MTC.

Background: - GI-6207 is an experimental cancer vaccine made with baker's yeast. The yeast has been modified to help the immune system target a protein called CEA. CEA is found on the surface of some kinds of tumor cells, including thyroid cancer cells. Researchers want to see if GI-6207 can encourage the body's immune system to attack and kill tumor cells that contain the CEA protein. They will test to see whether this vaccine is a safe and effective treatment for medullary thyroid cancer that has not responded to earlier treatments. Objectives: - To test the safety and effectiveness of the GI-6207 vaccine for advanced medullary thyroid cancer. Eligibility: - Individuals at least 18 years of age who have medullary thyroid cancer that has not responded to earlier treatments. Design: Participants will be screened with a physical exam and medical history. They will provide blood and tumor samples and have an imaging study of the neck and chest. They will also have a skin test to make sure that they are not allergic to the yeast in the vaccine. Participants will be divided into two groups. One group will start to take GI-6207 immediately for 1 year. The second group will have 6 months of monitoring and tests with no vaccine, and then will take GI-6207 for 1 year. GI-6207 will be given every other week for the first seven visits (about 3 months), and then monthly for the remaining year of treatment. It will be given as injections beneath the arm and in the upper thigh. These locations will help the vaccine enter the lymph nodes and reach the immune system more quickly. Participants will be monitored with frequent blood and urine tests and imaging studies. Participants will have regular follow-up visits after their year of study vaccines.

The aim of this study is to optimize pretargeting parameters using pharmacokinetic and imaging data for immuno-PET using anti-CEA x anti-HSG TF2 BsMAb and 150 MBq of 68Ga-IMP-288 peptide in MTC patients with abnormal Ct serum level after initial complete surgery and at least one abnormal lesion

The aim of the trial is to study a radiating diagnosis agent used in post surgery when the biological assessment highlighted a residual disease. This is an inter-regional multicentric, prospective study evaluating the benefit of PET F-DOPA imaging in involved node detection compared to standard imaging assessment in patient with medullary thyroid cancer. The purpose of the study is to evaluate the impact and performance of a new PET / CT (computerized tomography ) tracer targeting dopamine receptor in patient with residual ganglionar biological disease after initial surgery of medullary thyroid cancer compared to standard imaging. Obtained data will be compared to the "gold standard" based on : nodes cytology when they could be punctured histology when a new surgery will be recommended surveillance when the 2 first cases will be not applicable (imaging monitoring, evolution of thyrocalcitonin)

The primary objective of the trial is to test the new radio tracer 68Ga-NODAGA-E[c(RGDyK)]2 for PET imaging of angiogenesis. The tracer has the potential of identifying tumors with a high level of angiogenesis, which is one of the cancer hallmarks. Furthermore, the tracer can potentially be used in early response assessment to anti-angiogenic treatment. This is a first-in-man study to test the radio tracer in cancer patients. Safety, biodistribution and dosimetry will be evaluated by repeated PET imaging (10 minutes, 1 hour and 2 hours post injection).
