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.
The investigators plan a prospective study designed to optimize and translate noncontrast, novel Magnetic Resonance Imaging (MRI) techniques for detecting and measuring intestinal inflammation as well as for allowing early prediction of response to medical therapy in small bowel Crohn's Disease (CD).
This randomized, double-blind, placebo-controlled trial of doxazosin will assess doxazosin's effectiveness for PTSD nightmares, subjective sleep quality, and non-nightmare PTSD symptoms in adult men and women veterans with full and partial-syndromal PTSD.
Diabetes in pregnancy carries significant pregnancy specific risks and requires frequent glucose monitoring to reduce these risks. This project compares the effect of two incentive schemes on adherence rates of glucose testing in pregnancy.
The purpose of this study is to assess the safety and efficacy of nivolumab in combination with rucaparib, docetaxel, or enzalutamide in participants with castration-resistant prostate cancer that has spread.
This is a single, un-replicated visit to the Children's Metabolic Kitchen and Eating Behavior Lab designed to gather data on children's responses to images used in MRI studies. Additionally, a demographic questionnaire for parents will be piloted.
This study will evaluate the efficacy, safety, and pharmacokinetics of immunotherapy-based treatment combinations in participants with metastatic non-small cell lung cancer (NSCLC). Two cohorts will be enrolled in parallel in this study: Cohort 1 will consist of participants with tumor PD-L1 expression who have received no prior systemic therapy for metastatic NSCLC, and Cohort 2 will consist of participants who experienced disease progression during or following treatment with a platinum-containing regimen and a PD-L1/PD-1 checkpoint inhibitor, given in combination as one line of therapy or as two separate lines of therapy, regardless of PD-L1 expression. In each cohort, eligible participants will initially be assigned to one of several treatment arms (Stage 1). Participants who experience disease progression, loss of clinical benefit, or unacceptable toxicity during Stage 1 may be eligible to continue treatment with a different treatment regimen (Stage 2).
This phase I/II trial studies the side effects and best dose of liposomal irinotecan and rucaparib when given together with fluorouracil and leucovorin calcium and to see how well they work in treating patients with pancreatic, colorectal, gastroesophageal, or biliary cancer that has spread to other places in the body (metastatic). Chemotherapy drugs, such as liposomal irinotecan, fluorouracil, and leucovorin calcium, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. PARPs are proteins that help repair DNA mutations. PARP inhibitors, such as rucaparib, can keep PARP from working, so tumor cells can't repair themselves, and they may stop growing. Giving liposomal irinotecan and rucaparib together with fluorouracil and leucovorin calcium may work better in treating patients with pancreatic, colorectal, gastroesophageal, or biliary cancer.
In the setting of naloxone standing orders, this study will assess the impact of a targeted, web-based overdose prevention and naloxone intervention for patients prescribed chronic opioid therapy. Outcomes are changes in opioid risk behaviors, naloxone uptake, and knowledge about overdose and naloxone.
This clinical trial will evaluate the safety and feasibility of a humanized OX40 agonist, MEDI0562, in the pre-operative setting for patients with head and neck squamous cell carcinoma or melanoma.
Tinnitus, or ringing in the ears, is a very common problem that often accompanies hearing loss. It affects up to 1 in 10 adults, and about 30% of people who experience chronic tinnitus find it very distressing. In these patients, symptoms of depression and anxiety often accompany tinnitus and there are no approved treatments. Clinical trials are ongoing to test a glutamate NMDA receptor antagonist (called esketamine), which is injected into the inner ear. However, the preliminary results with this medication show that it only works for tinnitus that results from acute injury. It does not treat tinnitus resulting from progressive hearing loss. Research in humans and animals suggest that the neurotransmitters glutamate and GABA are important in the development and maintenance of tinnitus. This data shows that over-activation of the NMDA receptor and a decrease in GABA signaling in the brain play a crucial role. Previous studies show that ketamine, which an antagonist at the NMDA receptor, increases GABA levels in the brain in participants with depression. Thus, in this experiment, this study will test the effect of ketamine on tinnitus, since it blocks the NMDA glutamate receptor and increase GABA levels. Two groups of participants will be included in this study: those who experience distress (symptoms of anxiety or depression) with tinnitus and those who have tinnitus but do not experience distress. Each participant will receive both ketamine and placebo on different days. Magnetic Resonance Spectroscopy (MRS) scans will be
