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.
Magnetic resonance imaging, MRI, is a procedure that uses radio waves, a powerful magnet, and a computer to make a series of detailed pictures of areas inside the body. The goal of this study is to determine if MR fingerprinting, new way of acquiring MRI images, can help identify the extent of tumor spread in the brain, better than routine MRI images.
Assessment of dietary intake in large, free-living populations is inherently challenging due to the complex nature of human diet. Advancements in traditional methods of dietary assessment (i.e., web-based dietary recalls or records) have aimed at improving data accuracy while reducing participant burden. Further utilizing food recognition technologies to capture real-time food intake may aid in overcoming limitations of existing methods. Keenoa, an artificial intelligence-enhanced, image-assisted tool, is a newly designed mobile application that may facilitate collection of dietary data. Primarily, the investigators will assess acceptability and usability of Keenoa compared with the traditional, web-based Automatic Self-Administered 24-Hour (ASA24) Dietary Assessment Tool in the Framingham Heart Study Third Generation-based cohorts at examination 4. The investigators will also determine the proportion of participants who complete all three days of dietary assessment, either through Keenoa or ASA24. Further, the investigators will relate dietary determinants of glycemic variability (e.g., percent carbohydrate, fiber intake, etc.), obtained from each dietary assessment tool, to the continuous glucose monitor (CGM)-derived outcomes. With a randomized block design, this study will take place as part of the Framingham Heart Study (FHS) glucose study (R01 DK129305). Currently participants from the Third Generation-based cohorts are asked at their fourth examination to wear Dexcom G6 Pro continuous glucose monitor on either their arm or abdomen for a duration of at least 4 days. During this time, participants are asked to complete 3 consecutive days of dietary record through ASA24. For this trial, the investigators will randomize the dietary assessment tool weekly between ASA24 and Keenoa, therefore, depending on the week of administration, participants will be randomized to either a 3 days dietary record via ASA24 or a 3-day dietary record through Keenoa. This trial will last a total of 6 weeks.
RESTORE tests whether Augmented-FLS, where patients are contacted by a patient navigator (serving as the liaison) and referred to a bone health provider, is better than Enhanced Usual Care, which includes patient and PCP education and activation. We also aim to determine the influence of age, race, ethnicity, sex, poverty level, geographic region, and timing of entry into the trial after a fracture on the effectiveness of the two strategies.
The intent and design of this Phase 3 study is to assess vosoritide as a therapeutic option for the treatment of children with hypochondroplasia (HCH).
Opioid Use Disorder (OUD) is a complex, chronic condition affecting nearly 70,000 Veterans who can experience significantly reduced quality of life (e.g., poorer social, occupational, and health-related functioning). VA clinics providing Medication treatment for OUD (MOUD; e.g., buprenorphine, methadone), the 1st-line treatment for OUD, often face challenges in also attempting to treat Veteran functional needs, which may require them to extend beyond their available resources to provide support. There is an urgent need for functionally impactful and accessible treatments for Veterans in MOUD. Acceptance and Commitment Therapy (ACT) is a well-suited framework to support the functioning of Veterans in MOUD with over 20 years of research support. However, the traditional practice ACT requires a trained clinician to provide weekly, hour-long therapy sessions (typically for 12-16 weeks) and may be too burdensome for MOUD clinics to use alongside standard care. Fortunately, emerging research suggests that mobile health interventions (MHIs; e.g., smartphone apps) can overcome many of these pragmatic barriers. MHIs can efficiently deliver functionally-focused treatments focused on Veteran functioning in "real-world" settings, through minimally burdensome and accessible formats. Currently however, no MHI's targeting functioning exist for Veterans in MOUD. The proposed study will address this gap by developing and evaluating an early prototype of a targeted smartphone app designed to enhance the functional outcomes of Veterans receiving MOUD called "ACT to RECOVER" (Acceptance and Commitment Therapy to Reach Empowerment through Commitment, Openness, and Valuing Experiences in Recovery). The study will occur in 3 phases: Phase 1: Development. Develop content for ACT to RECOVER using Veteran (n=10) and provider feedback (n=10). Phase 2: Iterative Usability Assessment. Conduct field testing (3 rounds, n=4-5 per round) to refine ACT to RECOVER format, acceptability, and usability. Phase 3: Pilot ACT to RECOVER in a Stage 1b Randomized Controlled Trial (RCT). Conduct a pilot trial to compare ACT to RECOVER (n=20) to a smartphone-based symptom monitoring control group (n=20). - (3a) Evaluate the acceptability and feasibility of each condition's app and study procedures. - (3b) Explore changes in functional (e.g., values-based living, quality of life) and clinical outcomes (e.g., illicit opioid use) which will be key outcomes in future efficacy testing.
In this study, researchers will learn more about a study drug called BIIB080. BIIB080 is currently a drug under investigation for treatment of Alzheimer's disease. The main question researchers are trying to answer in this study is how radiolabeled BIIB080 distributes in the brain and spinal cord. To help answer this question, researchers will use positron emission tomography (PET) scanner that can detect radiolabeled BIIB080 after a single injection of a small dose of radiolabeled BIIB080 ([89Zr]Zr-DFO-BIIB080) and a dose of BIIB080 together via an intrathecal (IT) injection in healthy volunteers. Researchers will also learn about the safety of injecting radiolabeled BIIB080 and BIIB080 together.
This exploratory, proof-of-concept study is a double-blind (participants and investigators will be blinded), placebo-controlled, randomized, two-arm clinical trial of Marinol [dronabinol, synthetic Δ9-tetrahydrocannabinol (THC)] for chronic low back pain (cLBP) with a 2:1 allocation ratio. Up to 75 subjects will be enrolled in this pilot study and randomized to receive doses of THC (up to 30 mg/day), orally, over 8 weeks. This study will be conducted at a single site; it does not include any stratifications, and there is no interim analysis planned. Notably, the goal is to determine whether there is enough evidence of the safety of THC to support the development of later-phase clinical trials. Thus, detailed developmental plans are contingent on the outcomes of this study.
The goal of this pilot randomized clinical trial is to test the impact of a virtual reality program for improving the ability of emerging adults (age 18-25) with attention deficit hyperactivity disorder (ADHD) to stay focused while completing homework and studying. This study compares the impact of using a virtual reality headset to using a virtual reality headset while also receiving feedback about levels of focus to a control group. The main question is whether participants demonstrate significantly improved concentration while completing homework and studying in virtual reality and whether they enjoy and prefer working in a virtual reality environment. Concentration is measured both through participant report and also using keyboard and mouse click data to assess work productivity objectively.
The goal of this randomized controlled trial is to compare the effects of a clinical decision support tool consisting of a 48-hour stop order for indwelling urinary catheters versus no clinical decision support in hospitalized patients with indwelling urinary catheters. The main questions it aims to answer are: - Does the presence of an automated stop order integrated as part of a clinical decision support tool reduce dwell time of urinary catheters and the rate of catheter associated urinary tract infections? Participants who have indwelling urinary catheters ordered will be randomized to either have these orders automatically expire after 48 hours unless an action is taken or have orders without expiration. Researchers will compare the urinary catheter dwell time and the rate of catheter associated urinary tract infections between the two groups.
This phase Ib trial tests the safety, side effects, best dose and effectiveness of regorafenib in combination with venetoclax and azacitidine in treating patients with acute myeloid leukemia (AML) that has come back after a period of improvement (relapsed) or that has not responded to previous treatment (refractory). Regorafenib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps to slow or stop the spread of cancer cells. Venetoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. It may stop the growth of cancer cells by blocking BCL-2, a protein needed for cancer cell survival. Azacitidine is in a class of medications called demethylation agents. It works by helping the bone marrow to produce normal blood cells and by killing abnormal cells. Giving regorafenib in combination with venetoclax and azacitidine may be safe, tolerable and/or effective in treating patients with relapsed or refractory AML.
