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 goal of this clinical trial is to determine the pharmacodynamic effects of ALTO-203 in patients with MDD in a randomized, placebo-controlled, single-dose crossover treatment period. Additionally, safety, tolerability, and PK will be assessed in a subsequent randomized placebo-controlled multi-dose parallel-group treatment period of 28 days. Participants will complete subjective response questionnaires and perform cognitive tasks during the single-dose period, in which participants will receive ALTO-203 25 μg and 75 μg, as well as placebo. During the multiple-dose period, participants will receive either ALTO-203 25 μg, 75 μg , or placebo. Safety will be assessed over the single dose and 28-day multiple dose periods.
The goal of this pilot study is to assess the feasibility of adapting and delivering the existing home-based epilepsy self-management intervention, HOBSCOTCH, for people with Post Acute Covid Syndrome (PACS). The main questions it aims to answer are: Can the current HOBSCOTCH program be adapted for people with PACS? Will people with PACS experience improved quality of life similar to that found in people with epilepsy after participating in the HOBSCOTCH program? Participants will be asked to: - attend nine, one-hour virtual (online and/or by telephone) HOBSCOTCH-PACS sessions with a one-on-one certified HOBSCOTCH-PACS coach - complete a brief clinical questionnaire about their diagnosis of PACS - complete seven questionnaires before and after the HOBSCOTCH-PACS sessions about their quality of life, memory and thinking processes (objective and subjective cognition), about their physical and mental health and about autonomic symptoms associated with their diagnosis of PACS - keep a short daily diary (using a smart phone app or on paper) about their PACS symptoms and use of the self-management strategies taught in the HOBSCOTCH-PACS program - complete two brief surveys to assess satisfaction with their experience after the entire HOBSCOTCH-PACS program
Electrocortical stimulation (ECS) mapping is a procedure used during brain surgeries, for example when treating diseases like epilepsy or when removing brain tumors. ECS mapping helps surgeons locate areas of the cerebral cortex (the outer part of the brain) that are important for everyday tasks like movement and speech. ECS mapping has been used for decades, and is considered the "gold-standard" tool for locating important areas of cortex. Despite this long history, there is still no clear understanding of exactly how ECS works. The goal of this study is to learn details about the effects ECS has on the brain. The main questions the study aims to answer are: 1) how ECS affects the neurons of the cortex at the stimulation site; and 2) how ECS impacts brain regions that are critically important for human speech and language. These so-called "critical sites" can be physically distant from one another on the brain's surface, requiring extensive ECS mapping and long surgeries. Critical sites are thought to be part of a speech/language network of brain areas, and so the study's goal is to learn about how they are connected. In some participants, the brain's surface will also be slightly cooled. This is a painless procedure that does not harm the brain's function, but could provide insight as to which parts of the brain (the surface, or deeper parts) are responsible for the effects of ECS. By improving the understanding of how ECS affects the brain and improving the ability to identify critical sites, this study could potentially lead to shorter surgeries and better outcomes for future individuals who need this care. Participants will be recruited from among individuals who are undergoing brain surgery for epilepsy treatment or tumor removal. Participants will complete simple tasks like reading words or naming pictures, similar to standard testing that is already performed during their hospital stay.
The primary objective is to determine the pharmacokinetics (PK) of vonoprazan in breast milk of healthy lactating women who have received vonoprazan administered once daily for 4 consecutive days.
This phase I trial studies how well a ketogenic dietary intervention works to improve response to immunotherapy in patients with melanoma and kidney cancer that has spread from where it first started (primary site) to other places in the body (metastatic). A ketogenic diet (KD) means eating fewer carbohydrates and more fats. The purpose is to use ketones (normal breakdown from fat) instead of glucose (sugar) as an energy source. Researchers want to see whether a ketogenic diet can improve tumor response in patients receiving immune checkpoint inhibitors (ICI). ICI are newer treatment options that help the immune system better fight some cancers. Following a KD may improve tumor response in patients with metastatic melanoma and metastatic kidney cancer treated with ICI.
Emergency department visits provide an opportunity to identify people with undiagnosed, untreated, or uncontrolled high blood pressure. In Reach Out, we will test whether a mobile health intervention yields a greater reduction in blood pressure than usual care among individuals identified with high blood pressure during a safety-net emergency department visit. Subsequently, we will estimate the reduction in heart attack, stroke, and dementia if Reach Out were implemented across all U.S. safety-net emergency departments.
This is a Phase 2 clinical study of hyperpolarized (HP) 13C-pyruvate (13C), 15N-urea (13C,15N) metabolic MR imaging in prostate cancer patients who are undergoing or have received radiation therapy for prostate cancer.
This phase II trial tests how well pirtobrutinib in combination with rituximab works in treating patients with marginal zone lymphoma (MZL). Pirtobrutinib is a BTK inhibitor. It works by blocking the action of the protein that signals tumor cells to multiply. Rituximab is a monoclonal antibody. It binds to a protein called CD20, which is found on B cells (a type of white blood cell) and some types of cancer cells. This may help the immune system kill cancer cells. Giving pirtobrutinib in combination with rituximab may be an effective treatment for MZL.
This study seeks to explore changes in the neural pathways and arm function following a breathing intervention in the multiple sclerosis (MS) population. The breathing intervention, known as Acute Intermittent Hypoxia (AIH), involves breathing brief bouts of low levels of oxygen. Research has found AIH to be a safe and effective intervention resulting in increased ankle strength in people with MS. Here, the study examines arm and hand function before and after AIH. In order to better understand the brain and spinal cord response to AIH, the investigators will measure muscle response, and signals sent from the brain to the arm muscles before and after AIH.
This phase II MATCH treatment trial tests how well MLN0128 (TAK-228) works in treating patients with cancer that has certain genetic changes called TSC1 or TSC2 mutations. MLN0128 (TAK-228) may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
