Filter by:Serotonin has recently been identified as a major regulator of bone formation. Gut-derived serotonin inhibits bone formation, and early animal studies have shown that inhibition of gut-derived serotonin has anabolic effects on bone in ovariectomised rodents. This pathway has potential to be developed as a new anabolic treatment for osteoporosis in humans. Carcinoid neuro-endocrine tumours produce very high levels of serotonin, and so it might be expected that patients with carcinoid disease would have reduced bone formation, low bone mass and fractures. However, this has not been apparent in clinical practice. There may be a discrepancy between rodent models and human disease. This study aims to identify whether patients with carcinoid disease have reduced bone mass, reduced bone formation or high fracture rates. The investigators will conduct a cross-sectional observational case-control study of patients with carcinoid disease in the Sheffield neuro-endocrine tumour clinic and gender-, age- and body mass index (BMI)-matched controls.
The primary objective of this study is to analyse the concentration dopamine and serotonin in thrombocytes of patients with renal cell carcinoma and neuro-endocrine tumours compared to the concentrations of these catecholamines in healthy volunteers. The concentration dopamine and serotonin in thrombocytes with and without medication will also be evaluated.
The objective is to clarify Roux-en-Y anastomosis of the pancreatic stump decreases pancreatic fistula following distal pancreatectomy, compared with stapling closure of the pancreatic stump.
This study will estimate the treatment effect of everolimus in combination with pasireotide LAR relative to everolimus alone on progression-free survival (PFS) in patients with advanced progressive PNET
The aim of the study is to find out if the experimental medicine, YF476, can make gastric carcinoids, a rare type of stomach tumour, shrink and disappear. Gastric carcinoids occur mainly in patients with chronic atrophic gastritis (CAG), a condition in which the acid-producing cells in the lining of the stomach can't make acid. Acid production is controlled by gastrin, a hormone (chemical messenger) that's released into the bloodstream. If the stomach can't make acid, blood levels of gastrin rise. High blood levels of gastrin in patients with CAG can cause other cells (ECL cells) in the lining of the stomach to grow and, over the years, to give rise to gastric carcinoids. Gastric carcinoids are usually benign, but they can become malignant. Therefore, patients with CAG and gastric carcinoids have the inside of their stomach checked regularly, by gastroscopy, to see if the gastric carcinoids need removing surgically. A gastroscope is a thin (1 cm), flexible tube at end of which is a mini video camera, which enables the user to inspect the lining of the stomach and a 'snare' to take samples of tissue (biopsies). YF476 (netazepide) is a gastrin receptor antagonist (blocks the effects of gastrin), so it's a potential new medical treatment for gastric carcinoids in patients with CAG. Up to 10 of these patients will take YF476 daily for up to 12 weeks. If they benefit from that treatment, they may take YF476 daily for up to another 52 weeks. They'll make several outpatient visits for tests, including checks on the safety of YF476. At some of the visits, they'll have a gastroscopy. At each gastroscopy, the gastric carcinoids will be measured and biopsies taken for laboratory tests.
This is a pilot study for evaluation of 89Zr-bevacizumab PET imaging as predictive biomarker during treatment with everolimus in patients with neuroendocrine tumors. Patients with progressive disease during the last year will receive treatment with everolimus 10 mg/day orally and 89Zr-bevacizumab PET imaging will be performed before start of treatment and after 2 and 12 weeks of treatment in the first three patients. If the scan after 2 weeks of treatment is already informative further patients will not undergo a scan at 12 weeks. A scan is considered already informative if both scans show at least 30% decrease in uptake in case of response, or at least 30% increase in uptake in case of disease progression. Four days before the scan patients will be injected intravenously 37 MBq, protein dose 5 mg 89Zr-bevacizumab. At day 1, day 15 and day 99, PET images will be made for visualization and quantification of VEGF in the tumor lesions and blood will be drawn for determination of angiogenesis and mTOR pathway related biomarkers.
The purpose of this protocol is to allow continued treatment with conatumumab and/or ganitumab, with or without chemotherapy, to participants who completed a separate Amgen-sponsored conatumumab or ganitumab study without disease progression whose previous studies were closed.
The present study is designed to collect safety/tolerability data and explore the efficacy of RAD001 in advanced pulmonary neuroendocrine tumor in Chinese patients.
This is a multi-centric, open-label study evaluating the efficacy and safety of RAD001 in patients with advanced (stage IV) Lung Cancer (Large Cell) with neuroendocrine differentiation treated with a combination of RAD001 with paclitaxel and carboplatin.
The goal of this clinical research study is to learn if the study drug, Pasireotide LAR can shrink or slow the growth of Metastatic Neuroendocrine Carcinomas. The safety of this drug will also be studied. The patient's physical state, changes in the size of the tumor, and laboratory findings taken while on-study will help us decide if Pasireotide LAR is safe and effective.
