NCT07111663
This is an observational study in individuals with isolated (or primary) dystonia that involves more than one body region. The purpose of the study is to collect detailed information to help your physician and other researchers understand how dystonia impacts your and other patients' lives and how the disease changes over time. The study may also help researchers better understand the clinical scales that are commonly used to evaluate dystonia symptoms and how they affect various areas of life such as well-being, pain, relationships and social interactions, and progress over time. Because this is an observational study, you will not receive any interventional treatment in the study.
NCT04798768
The MODULAR ATP Clinical Study is designed to demonstrate safety, performance, and effectiveness of the Modular Cardiac Rhythm Management (mCRM) Therapy System.
NCT01522976
This randomized phase II/III trial studies how well azacitidine works with or without lenalidomide or vorinostat in treating patients with higher-risk myelodysplastic syndromes or chronic myelomonocytic leukemia. Drugs used in chemotherapy, such as azacitidine, work in different ways to stop the growth of cancer cells, either by killing the cells, stopping them from dividing, or by stopping them from spreading. Lenalidomide may stop the growth of cancer cells by stopping blood flow to the cancer. Vorinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. It is not yet known whether azacitidine is more effective with or without lenalidomide or vorinostat in treating myelodysplastic syndromes or chronic myelomonocytic leukemia.
NCT06807437
This phase III trial compares the effect of using lanreotide before surgery to surgery alone in preventing pancreatic fistulas in patients with pancreatic cancer or a pancreatic lesion that could become cancerous. Lanreotide, a type of somatostatin analog similar to somatostatin (a hormone made by the body), and is used to treat certain types of gastroenteropancreatic neuroendocrine tumors, and carcinoid syndrome. It may help stop the body from making extra amounts of certain hormones, including growth hormone, insulin, glucagon, and hormones that affect digestion. It may also help keep certain types of tumor cells from growing. Patients with pancreatic cancer or pancreatic lesions may undergo surgery to remove parts of the pancreas, also called a distal pancreatectomy. Patients may experience complications after surgery, including pancreatic fistulas. A pancreatic fistula occurs when there is a small leak from the pancreas, causing fluids to collect. This can often lead to infection and other problems. Giving lanreotide before undergoing distal pancreatectomy may be more effective than surgery alone in preventing the development of a pancreatic fistula in patients with pancreatic cancer or a pancreatic lesion that could become cancerous.
NCT06613698
The goal of this study is to assess the safety and efficacy of GSK4532990 in participants with alcohol-related liver disease.
NCT00523627
This study, conducted at the NIH Clinical Research Unit at the Phoenix Indian Medical Center, will examine how the body s metabolism (energy expenditure) changes when people overeat and when they fast and how different diets (e.g., high-protein or high-fat) affect metabolism. The results may provide information about whether there are mechanisms that make some people more resistant than others to gaining weight when they eat more. Non-smoking healthy subjects between 18 and 55 years of age who weigh no more than 350 pounds may be eligible for this study. Participants undergo the following procedures: * Pregnancy test for women of childbearing age. * Oral glucose tolerance test. For this test, an I.V. line (needle attached to a plastic tube) is inserted into a vein to allow several blood draws without repeated needle sticks. After the first blood sample is drawn, the subject drinks a cola-flavored sugar solution. Five additional blood samples are then drawn over 3 hours. * Blood test for DNA (genetic) studies related to obesity, diabetes and related medical problems. * DEXA scan. This test measures body fat. The subject lies on a table while a very small dose of X-rays is passed through the body. * Respiratory chamber. This test measures how many calories the body burns a day and assesses energy balance between intake and expenditure. Subjects stay in a room with two windows, equipped with a sink, toilet, television and DVD player, desk, chair, telephone and bed for 24 hours. The test is repeated five times during the first 18-day admission and 3 times during the second 13-day admission. For the first two sessions, subjects are fed a diet equal to the amount of energy their body uses. For the next 6 stays they are fed double the amount of calories their body usually uses for 5 of the stays and fast (consume nothing but water and soda without caffeine or calories) during 1 stay. The overfeeding diets may be high or low in protein, normal in protein, or high in fat. Blood tests are done on the day of each respiratory chamber session and a 24-hour urine sample is collected for one day while in the chamber. * Eating behavior questionnaires. * Psychological performance tests. Some participants are asked to volunteer to repeat two of the chamber studies to validate the measurements. The repeat session includes only the fasting and the overfeeding with normal protein content. All participants are followed at 6 months with blood tests, a DEXA scan, and urine tests (including pregnancy test for women). At annual visits for years 1 through 7, participants have the 6-month tests plus an oral glucose tolerance test.
NCT07126262

NCT06383403
The participants in this study will have confirmed PBC with inadequate response or intolerance to Ursodeoxycholic acid (UDCA), which is a medication used in the management and treatment of cholestatic liver disease. Primary biliary cholangitis is a slowly progressive disease characterised by damage of the bile ducts in the liver, leading to a build-up of bile acids which causes further damage. The liver damage in PBC may lead to scarring (cirrhosis). PBC may also be associated with multiple symptoms. Many patients with PBC may require a liver transplant or may die if the disease progresses and a liver transplant is not done. This study will compare a daily dose of elafibranor (the study drug) to a daily dose of placebo (a dummy treatment). The main aim of this study is to determine if elafibranor is better than placebo in reducing ALP levels to a normal value. High ALP levels in the blood can indicate liver disease. There will be three periods in this study: A screening period (up to 8 weeks) to assess whether the participant can take part; a treatment period (up to 52 weeks) where eligible participants will be grouped as per their blood ALP levels and randomly assigned to either receive elafibranor or placebo, and a follow-up period (4 weeks) where participants' health will be monitored. Participants will be twice as likely to receive elafibranor than placebo (2:1 ratio). Participants will undergo blood sampling, urine collections, physical examinations, clinical evaluations, electrocardiograms (ECG: recording of the electrical activity of heart), ultrasound examinations (a noninvasive test that passes a probe over skin to look at the bladder, urinary tract, and liver), and Fibroscan® examinations (a noninvasive test that passes a probe on skin to measure stiffness of the liver). They will also be asked to fill in questionnaires. Each participant will be in this study for up to 64 weeks (15 months).
NCT04336722
Double-blind, randomized, placebo-controlled, Phase 3 study to investigate the efficacy and safety of odevixibat compared to placebo in children with biliary atresia who have undergone a Kasai hepatoportoenterostomy.
NCT04729959
This phase II trial studies the best dose and effect of tocilizumab in combination with atezolizumab and stereotactic radiation therapy in treating glioblastoma patients whose tumor has come back after initial treatment (recurrent). Tocilizumab is a monoclonal antibody that binds to receptors for a protein called interleukin-6 (IL-6), which is made by white blood cells and other cells in the body as well as certain types of cancer. This may help lower the body's immune response and reduce inflammation. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Fractionated stereotactic radiation therapy uses special equipment to precisely deliver multiple, smaller doses of radiation spread over several treatment sessions to the tumor. The goal of this study is to change a tumor that is unresponsive to cancer therapy into a more responsive one. Therapy with fractionated stereotactic radiotherapy in combination with tocilizumab may suppress the inhibitory effect of immune cells surrounding the tumor and consequently allow an immunotherapy treatment by atezolizumab to activate the immune response against the tumor. Combination therapy with tocilizumab, atezolizumab and fractionated stereotactic radiation therapy may shrink or stabilize the cancer better than radiation therapy alone in patients with recurrent glioblastoma.
