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 phase I trial tests whether metformin works in reducing the annual transformation (development of invasive cancer) of oral precancerous lesions into cancerous lesions. Metformin is a drug approved for the treatment of diabetes, but studies have shown that it may have some anticancer properties. Giving metformin may help prevent or slow the development of oral cancer from precancerous lesions.
The aim of the project is to advance our understanding of how individuals with Posttraumatic Stress Disorder (PTSD) experience symptoms in their every-day lives when they are in their home environment. To date, all PTSD assessments are retrospective; individuals with PTSD are asked to recount and report their symptoms over the past weeks or months. Such assessment procedures are negatively impacted by individuals' abilities to accurately recall information. Moreover, retrospective assessments provide little information about how symptoms are experienced in the moment and how these experiences then lead to other behaviors. The proposed project addresses these limitations by assessing PTSD symptoms and associated biological markers (e.g., sleep, heart rate, heart rate variability) in real-time by asking subjects to wear a smart device and complete brief surveys. Data will be collected from 50 individuals with PTSD and 20 healthy controls to help us better understand individuals' real-time experience with PTSD and lay the foundation to develop algorithms for possible in-the-moment interventions in the future.
Researchers are looking for a better way to treat people who have chronic heart failure. Chronic heart failure is a medical condition with shortness of breath, tiredness and ankle swelling in which the heart does not pump blood as well as it should. BAY2413555 is a new compound which is under development for the treatment of heart failure. Heart failure is a serious disease in which the heart pumps less well. BAY2413555 is expected to protect the heart and improve cardiac function. The main purpose of this study is to learn how safe BAY2413555 is compared to placebo in participants with chronic heart failure and implanted cardiac defibrillator, or cardiac resynchronization devices (ICD/CRT). A placebo is a treatment that looks like a medicine, but does not have any medicine in it. ICD/CRT are machines placed in the body that use an electric shock/impulse to reset the heart or get it beating correctly. To study the safety, the researchers will record all medical problems the participants may have during the study after starting the study treatment. Medical problems that happen after the participants have started their treatment are also known as "treatment emergent adverse events" (TEAEs). The TEAEs will be compared between participants who received BAY2413555 and those who received placebo. The second purpose of this study is to learn whether BAY2413555 effects electrical signals inside the heart compared to placebo. The study has two parts, A and B. Each part will last for two weeks. In part A, the participants will be assigned by chance to either take BAY2413555 as a tablet by mouth once per day or a placebo. Participants from part A who do not need to stop the study based on predefined criteria continue in part B. They will be assigned by chance to receive either the same dose of BAY2413555 as in part A or a higher dose. Participants who have taken placebo in part A will as well be assigned in part B. Each participant will be in the study for approximately 90 days (including the screening period and follow-up period). In the study, participants will take study medication for 28 days. 8 visits to the study site and 1 telephone contact visit are planned. During the study, the study team will: - do physical examinations - check vital signs - examine heart health using ECG - check the participants' ICD/CRT information - take exercise testing - take blood and urine samples - ask the participants questions about how they are feeling about their quality of life - ask the participants questions about how they are feeling and what adverse events they are having. An adverse event is any problem that happens during the trial. Doctors keep track of all adverse events that happen in trials, even if they do not think the adverse events might be related to the study treatments or a study procedure. Participants will be closely monitored during the entire study duration and site personnel will take action to mitigate any negative effect, if any, as appropriate. About 30 days after the participants take their last treatment, the study doctors and their team will check the participants' health.
This is a Phase 2, multicenter, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of subcutaneous lirentelimab (AK002) in adult subjects with H-1 antihistamine refractory chronic spontaneous urticaria. Subjects who complete the randomized, double-blind, placebo-controlled treatment period may have the option to enroll in an open-label extension period and receive up to 6 doses of subcutaneous lirentelimab.
The purpose of this study is to develop a new remote-based video assessment outcome measure for Limb-Girdle Muscular Dystrophy (LGMD) trials. The overall objectives for this study are: 1. Identify domains and tasks meaningful to participants with a Limb-Girdle Muscular Dystrophy (LGMD) for development of the LGVA, including considerations for subtype heterogeneity and functional subgroup branching; 2. Determine the feasibility and reliability of the LGVA with test-retest of the LGVA Video Capture Manual; 3. Assess and refine the LGVA Video Capture Manual to ensure standardization and incorporate feedback from participants; 4. Collect source material videos using the LGVA Video Capture Manual to support the development of scorecards for the LGVA.
This is an open-label extension study to continue to evaluate the safety, tolerability and efficacy of the Repetitive Transcranial Magnetic Stimulation (rTMS) in subjects with schizophrenia or schizoaffective disorder who previously completed the treatment study of the protocol #8116 (NCT05319080). Protocol #8116 investigates the clinical efficacy of open-label individualized MRI-guided TMS applied to the left temporoparietal junction (TPJ) in schizophrenia patients. Participating patients who have completed the 4-week project #8116 can be screened for eligibility for this extension study in which they will continue treatment/assessment. They will be divided into three groups (non-responders, partial responders, or full responders) based on a reduction in the Auditory Hallucination Rating Scale (AHRS) scores from the study #8116.
A first-in-human study using TT-816 as a single agent and in combination with a PD-1 inhibitor in advanced cancers.
The purpose of this research is to study the safety and tolerability and to establish the maximum tolerated dose (MTD) of the combination of two drugs, fedratinib and decitabine, for the treatment of advanced-phase MPNs.
This is a single-center, randomized, double-blind, placebo-controlled study exploring the effects of a yeast-derived β-glucan on clinically significant fatigue among survivors of autologous HCT due to multiple myeloma. The primary aim is to evaluate the effect of β-glucan supplementation on changes in fatigue symptoms, as assessed by the Brief Fatigue Inventory (BFI) global fatigue score, by testing the differences in changes in scores from baseline to the mid-point (mean of weeks 1-4) and to the end of the intervention (mean of weeks 5-8).
Background: Major depressive disorder (MDD) may have many underlying causes. One theory is that brain cells with low levels of a molecule called cyclic AMP (cAMP) may cause depression. A drug called ketamine may increase the levels of cAMP in a person's brain cells. Objective: To find out if administering ketamine to people with depression affects cAMP levels in their brains. Eligibility: People aged 18 to 70 with MDD who are enrolled in another NIH study that uses ketamine. Design: Participants will visit the NIH clinic 5 times in up to 6 weeks. Some of the visits may be spread out over more than 1 day. Participants will be screened. They will have a physical exam with blood and urine tests. They will have a test of their heart function. They will have a psychiatric evaluation. They will answer questions about their family history and mental health. Participants will have a positron emission tomography (PET) scan. A small amount of a radioactive drug will be injected into a vein in their arm. Participants will lie on a bed that slides in and out of a doughnut-shaped machine that records images of their brains. They will have their heads in a holder to prevent movement. Each scan will last up to 2 hours. After their first PET scan, participants will receive ketamine in a different study they are enrolled in. Then they will come back for another PET scan with the radioactive drug. Participants will also have another scan called an MRI. They will lie on a table that slides into a metal tube. They will lie still for up to an hour....
