There are about 173942 clinical studies being (or have been) conducted in United States. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
This project is a global, multicenter, prospective, longitudinal, observational natural history study that can be used to understand the disease progression and support the development of safe and effective drugs and biological products for Friedreich ataxia.
This phase IV trial evaluates how well giving standard of care (SOC) peptide receptor radionuclide therapy (PRRT) after SOC surgical removal of as much tumor as possible (debulking surgery) works in treating patients with grade 1 or 2, somatostatin receptor (SSTR) positive, gastroenteropancreatic neuroendocrine tumors (GEP-NETs) that have spread from where they first started (primary site) to the liver (hepatic metastasis). Lutetium Lu 177 dotatate is a radioactive drug that uses targeted radiation to kill tumor cells. Lutetium Lu 177 dotatate includes a radioactive form (an isotope) of the element called lutetium. This radioactive isotope (Lu-177) is attached to a molecule called dotatate. On the surface of GEP-NET tumor cells, a receptor called a somatostatin receptor binds to dotatate. When this binding occurs, the lutetium Lu 177 dotatate drug then enters somatostatin receptor-positive tumor cells, and radiation emitted by Lu-177 helps kill the cells. Giving lutetium Lu 177 dotatate after surgical debulking may better treat patients with grade 1/2 GEP-NETs
The participants of this study will have confirmed Primary Biliary Cholangitis (PBC). Participants will also have inadequate response or intolerance to ursodeoxycholic acid (UDCA) a drug used to treat PBC. PBC is a disease that progresses slowly. It causes damage to 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 people with PBC may require 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). Each participant will be in the study up to about 7 years. The main aim of this study is to determine if elafibranor is better than placebo in preventing clinical outcome events showing disease worsening (including progression of disease leading to liver transplant or death). This study will also study the safety of long-term treatment with elafibranor, as well as the impact on symptoms such as itching and tiredness.
Despite the significant morbidity and mortality associated with catatonia in autism, no diagnostic research has attempted to identify biomarkers for catatonia. This application will use a participant's own individual brain magnetic resonance image to target the primary motor strip with transcranial magnetic stimulation; to determine if hyper-excitability of the brain directly correlates with symptoms of catatonia and social-emotional impairment in autism. Completion of this project would result in the first study to associate hyper-excitability of the brain with catatonia and core features of autism; findings which are likely to have a significant impact on the health and well-being of autistic individuals.
This phase 3 clinical trial compares the safety and efficacy of palazestrant (OP-1250) to the standard-of-care options of fulvestrant or an aromatase inhibitor in women and men with breast cancer whose disease has advanced on one endocrine therapy in combination with a CDK4/6 inhibitor.
This phase I trial tests the feasibility, acceptability, and preliminary effectiveness of online dietary and resistance training to improve physical function in older (greater than or equal to 65-years old) cancer survivors. Declines in adequate protein and calorie intake results in faster loss of muscle mass and physical functioning in older adults. A novel approach to improving physical function in older cancer survivors (OCS) is to utilize online, tailored education and counseling from registered dietitians and exercise scientists, to improve dietary intake (protein intake, diet quality) and participation in resistance exercise. The purpose of this study is to help researchers learn whether an online dietary and resistance training intervention improves diet, exercise, physical function, and health outcomes in OCS.
This Anchillary project uses a refined technique of ultrasound-guided microneurography of the human cervical vagus nerve, an approach developed by Professor Vaughan Macefield and used safely to-date in 44 prior study participants. The overall goal of this project is to build upon prior data obtained using this approach by undertaking a detailed neurophysiological investigation of the human vagus nerve and to identify the nerve fibers activated during vagal nerve stimulation (VNS) in participants with implanted VNS devices in response to different stimulation parameters. In addition to providing data in unprecedented detail into the physiology of the human vagus nerve, this project will investigate different stimulus intensities, durations and frequencies that differentially excite myelinated and unmyelinated nerve fibers. These results will inform the CSP and guide future development of novel neural interfaces for VNS for various clinical applications.
Testing a Causal Model of Cognitive Control Deficits in Posttraumatic Stress Disorder (PTSD)
The goal of this observational study is to determine the feasibility of conducting a large-scale study on the effect of using osteopathic manipulative treatment (OMT) to treat patients with post-COVID-19 symptoms. The main questions it aims to answer are: 1. Is it feasible to conduct a large-scale study of the effect of OMT on patients with post-COVID-19 symptoms (based on how many patients agree to participate and how many complete the study)? 2. How much change in patients' post-COVID-19 symptom severity, quality of life, and ability to return to work can we expect to see following OMT? Participants will receive OMT as directed by their physician and complete questionnaires after every other OMT session. 1. Participants will complete questionnaires about their post-COVID-19 symptoms, quality of life, ability to return to work, and adverse events they experienced 3 days after every other OMT session. 2. Participants will be sent links to the questionnaires for 4 months or when their symptoms resolve, whichever comes first. 3. Additionally, participants will complete a follow-up questionnaire 2 months after they stop receiving OMT for their post-COVID-19 symptoms or 6 months after enrollment in the study, whichever comes first.
The goal of this N-of-1 study is to learn about treatment for individual patients who have rheumatoid arthritis (RA,) for which many treatments are available. The treatments are different in how they work, the way they are given, side- effects, and cost. While treatment guidelines are available, finding the best treatment order of treatments is often based on physician choice. The main question this study aims to answer are: - What are the effects of different treatments on RA symptoms and condition for each individual patient - What is the effectiveness of different treatments across all patients enrolled in the N-of-1 study Participants will be enrolled and randomized to a sequence of three U.S. Food and Drug Administration (FDA) approved RA medications: 1. adalimumab, 2. sarilumab, and 3. upadacitinib. Participants will be asked to complete questionnaires about their condition and quality of life weekly (either in clinic or remotely) and report their level of pain daily (remotely).
