Active clinical trials for "Neuroendocrine Tumors"

This is a prospective study of rare neuroendocrine and adrenal tumors. Subjects will be enrolled via informed consent, and blood and/or saliva and tissue will be collected. This is designed to work in conjunction with IRB#831990 which is a retrospective protocol. The University of Pennsylvania will be a contributing site with the University of Michigan as the coordinating site for the A5 alliance, a multi-institutional collaborative designed to study neuroendocrine and adrenal tumors.

This phase I/II trial studies how well gallium Ga 68-DOTA-TOC positron emission tomography (PET)/computed tomography (CT) or PET/magnetic resonance imaging (MRI) works in imaging patients with somatostatin receptor positive tumors. Gallium Ga 68-DOTA-TOC binds to somatostatin receptor positive tumors and can be seen using a PET scan. A PET scan uses a special camera to detect energy given off from gallium Ga 68-DOTA-TOC, to make detailed pictures of areas where material accumulates in the body. Diagnostic procedures, such as gallium Ga 68-DOTA-TOC PET/CT or PET/MRI, may help find and diagnose somatostatin receptor positive tumors and help plan the best treatment.

Pasireotide binds to somatostatin receptors sst2 and sst5, which can lead to significant hyperglycemia. The investigators would like to administer pasireotide as a treatment for refractory hypoglycemia in the setting of metastatic insulin-producing pancreatic neuro-endocrine tumor.

Taking part in clinical trials usually favors a particular demographic group. But there is limited research available to explain what trial attributes affect the completion of these specific demographic groups. This research will admit a wide range of data on the clinical study experience of neuroendocrine tumor patients to determine which factors prevail in limiting a patient's ability to join or finish a trial. It will also try to analyze data from the perspective of different demographic groups to check for recurring trends which might yield insights for the sake of future patients with neuroendocrine tumor.

The study consists of having participants complete quality of life questionnaires (PROMs) at the time of the cures +/- one week and in the middle of the intercure time +/- one week. As all the collection times do not correspond to a consultation or a visit to a medical service, The investigator wanted to develop a remote, computerized data collection solution. Researchers have programmed an AURA-RIV-TNE care pathway (MOCAs: Engine for the organization and coordination of health acts) on the myHCL patient environment, taking up the course of the study presented in the form of a table in paragraph 6.2. Once the patient consents to participate in the study, he must create an account on the patient interface of his investigation center (myHCL, myCHUGA etc) as much as possible to facilitate data extraction. Once the patient consents to participate in the study, the MOCAs AURA-RIV-TNE course will be associated with him in the Easily software, by defining the date week 0 (baseline) of the first treatment. This will allow automated sending of MAIL and SMS reminders at each questionnaire time. The MAILs will contain an internet link allowing the participant to be directly written to the questionnaires to be completed. A reminder system will be possible if the patient does not complete the questionnaire.

This is a phase II clinical trial to assess the efficacy of the combination of metronomic cyclophosphamide and tailored sorafenib dosing in advanced, progressive NET. NET are highly vascular tumors, and high VEGF expression has been correlated with worse clinical and pathological characteristics as well as poor prognosis. A novel antiangiogenic approach relies on targeting not only the endothelial cells but also rendering them more sensitive to VEGFR blockade by achieving pericyte detachment. In this study, the dose of sorafenib will be titrated up to a maximum of 800mg BID based on patients' toxicity and on a novel pharmacodynamic assay that measures inhibition of molecular target(PDGFR) in patients' peripheral blood mononuclear cells. Dual VEGFR targeting is achieved by administering sorafenib plus metronomic low dose cyclophosphamide.

Everolimus represents an approved therapy for patients with advanced well/moderately differentiated pancreatic NETs. Although some patients could benefit from this drug in terms of long-term tumor growth control, others are resistant upfront or become resistant during treatment. Therefore, it is crucial to detect some biological factors which can help to identify the responsive tumors. Given that Everolimus is a biological agent and its mechanism of action can be partially directed towards angiogenesis its effects can be studied on different levels and with different methods. Upfront and early surrogate predictive markers of activity/efficacy can be studied on tumor tissue, tumor imaging, and peripheral blood. mTOR pathways alterations, circulating endothelial cells, and other circulating angoigenic factors will be correlated with clinical outcome. Tumor perfusion and circulating markers will be studied also as markers of response compared with the morphological imaging.

The laser tissue welding device is intended for use in patients requiring sealing of the pancreas after partial pancreatectomy, and including those patients who are fully heparinized or have hemodilutional coagulation failure. The hypothesis is that the laser tissue welding device is safe and effective in sealing the pancreas, thereby decreasing the blood loss (operative and post-operative), and pancreatic juice leakage for patients when the Laser Tissue Welding device is used after pancreatic resection.

Primary Objective: To assess how an amino acid based medical food (Enterade®) helps maintain the intestine's ability to absorb and retain fluids, leading to a reduction in diarrhea due to Neuroendocrine Tumors (NET) and/or Carcinoid Syndrome. This improvement in the absorption will be assessed in part by evaluating changes in average daily stool frequency from baseline in patients receiving Enterade®. Each subject serves as his or her own control. Secondary Objectives: To assess subject reported health-related quality of life in subjects before and after compound administration. To characterize the side effect profile and tolerability of Enterade® as measured by the number of total 8-oz Enterade® bottles consumed throughout the trial, and average drinks per day. To evaluate changes in serum electrolytes before and after administration of Eenterade®. To assess intravenous fluid requirement and/or hospitalization for dehydration secondary to diarrhea between control observation period and active Enterade® period. To evaluate difference in utilization of standard-of-care anti-diarrheal medications between control observation period and Enterade® period. To compare subjective feeling of bloating and flatulence before and after administration of Enterade®. To evaluate changes in patient weight before and after administration of Enterade®.

The purpose of this study is to confirm the safety and efficacy of sunitinib in subjects with unresectable pancreatic neuroendocrine tumors.
