Filter by: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. They'll make up to seven outpatient visits for tests, including checks on the safety of YF476 and up to four gastroscopies. At each gastroscopy, the gastric carcinoids will be measured and biopsies taken for laboratory tests. Patients will take up to 24 weeks to finish the study.
The main purpose of this study is to see whether Axitinib will help prolong the time that the patient's carcinoid tumors remain stable, and to examine their treatment response through testing. Researchers also want to find out if Axitinib is safe and tolerable.
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.
Neuroendocrine cancer is an unusual disease and often goes undetected by routine imaging. The 68Ga-DOTATATE PET scan is a new generation of scans that might have improved sensitivity and resolution specifically for neuroendocrine tumors. The investigators will scan people with this cancer and compare it to other conventional imaging methods to see if it improves patient care.
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.
The primary objectives are: Dose escalation: 1. To determine the MTD and DLT(s) of TH-302 when used in combination with sunitinib. Dose expansion: 1. To make a preliminary assessment of the efficacy of TH-302 in combination with sunitinib as determined by the response rate and the progression-free survival in subjects with advanced RCC treated at the RP2D 2. To assess the safety of TH-302 in combination with sunitinib and determine a recommended Phase 2 dose of the combination. The secondary objectives are: Dose expansion: 1. To make a preliminary assessment of the efficacy of TH-302 in combination with sunitinib as determined by stable disease or better rate, duration of response and overall survival in subjects with advanced RCC treated at the RP2D. The exploratory objective is: 1. To explore the association of serum hypoxia biomarkers with efficacy endpoints.
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 study is designed to study the safety and effectiveness of 123I-MIBG as a diagnostic imaging agent in evaluating patients with known or suspected neuroendocrine tumors.

At each gastroscopy, the gastric carcinoids will be measured and biopsies taken for laboratory tests.
