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 is a Phase 1, single-center, nonrandomized, open-label, 2-part, fixed-sequence, drug-drug interaction (DDI) study to assess the effect of multiple doses of itraconazole, a CYP3A4 enzyme inhibitor, on the single dose PK of AZD4205 in healthy adult subjects (Part A) and to assess the effect of multiple doses of carbamazepine, a CYP3A4 inducer, on the single dose PK of AZD4205 in healthy adult subjects (Part B).
The purpose of this study is to test a stress management program for men with early-stage prostate cancer.
CT-155 is a novel prescription digital therapeutic (PDT) to treat schizophrenia
This study compares how three doses of semaglutide work in participants with type 2 diabetes (T2D) and overweight who are taking metformin. The study will look mainly at how well participant's blood sugar and participant's body weight are controlled when they are taking the study medicine at different doses. Participants will either get semaglutide [2 milligrams (mg), 8 mg, or 16 mg] or semaglutide placebo (a dummy medicine). Participants will take the study medicine with an injection pen called NovoPen®4. The injection pen is a medical tool with a needle used to inject the study medicine under the skin. The study will last for about 52 weeks. Participants will have 13 clinic visits and 4 phone calls.
Researchers are looking for a better way to relieve pain in people, such as after dental surgery. Participants in this study, have had 3 or 4 third molars (cheek teeth) removed and subsequently have moderate to severe tooth pain. The study treatment naproxen sodium suppresses inflammatory pain by reducing inflammation. In the US, naproxen has been marketed since 1976, and naproxen sodium has been approved for over-the-counter (OTC) use since 1994 for the temporary relief of minor aches and pains. Caffeine, which is generally consumed as coffee, tea, or cocoa, has been shown to enhance the effect of various painkillers, and therefore is accepted as an additive. The main purpose of this study is to learn how well a fixed-dose combination of naproxen sodium and caffeine relieves pain compared to each single ingredient as well as to placebo in participants after molar removal. A placebo is a treatment that looks like a medicine but does not have any medicine in it. To answer this, the researchers will compare the amount of pain decrease over 8 hours in participants who received a single dose of either: - 1 fixed-dose tablet of naproxen sodium/caffeine - 2 fixed-dose tablets of naproxen sodium/caffeine - naproxen sodium only - caffeine only - or placebo The study participants will be randomly (by chance) assigned to one of the five treatment groups. They will take a single dose of two tablets by mouth within 4.5 hours after the surgery. If there is no pain relief within 2 hours after intake, other painkillers may be given.
This study tests the remineralization of donor teeth (donorMIH) in situ in participants using 10% hydroxyapatite (HAP) toothpaste and sodium fluoride toothpaste.
This study will aim to undertake a preference evaluation comparing the Aria Health Aria Free™ to a competitor's device by assessing overall satisfaction and preference of the devices individually and in comparison to one another. Twenty (20) subjects will be enrolled on this study at one study site in Houston, Texas.
This pilot study of 16 patients will demonstrate a specific psychologically focused intervention to affect a spiritual aspect of psychological health and will measure (1) its effects on general distress, depression, anxiety and well-being; (2) healing and psychological impact beyond that accounted by usual personality factors; (3) its effect in correlation to measures of spirituality; (4) with neuroimaging, possible biological changes associated with this intervention. A. Objectives 1. Pilot a psychological intervention that impacts a "spiritual" level. 2. Measure efficacy improving well-being beyond explanation by usual personality factors. 3. Identify biological changes with neuroimaging. B. Hypotheses / Research Question(s) Studies demonstrate a healing effect beyond usual psychological and medical health to include a "spiritual" aspect with added experience of wholeness and well-being. Benefits are beyond just symptom relief but methods to achieve this are not well-defined. This study will provide a specific intervention and measure psychological and neuroimaging effects of the intervention. Hypotheses of Specific Results (see Study Instruments below) 1. DASS-21-shows significant decrease in depression, anxiety and overall stress. 2. PCL-5 - shows decrease 5-10 points (5 points=response, 10 points=clinically meaningful). 3. NIH-HEALS - shows significant increase overall and in all 3 factors. 4. WEMWBS - shows increase of greater than 3 points, considered "meaningful change." 5. Contingencies of Self-Worth Scale-shows significant global increase, positively correlated with increase in Mysticism Scale scores with post-intervention total above standardized mean. 6. A relevant portion of outcome improvement on DASS-21, NIH-HEALS, and ASPIRES will NOT be accountable by personality factors measured by NEO-FFI-3. 7. ASPIRES-shows significant increase in transcendence, no change in religious sentiments. 8. Neuroimaging-shows reduced activity in SPL, TPJ, MPFC, and IPL (see Research Significance).
The primary purpose of this study is to investigate the combined effects of sequential meal variety and portion size on food intake at a meal. Additionally, other individual characteristics will be examined for their influence on the effects of simultaneous variety and portion size on meal intake.
Background: The COVID-19 pandemic infected and killed African Americans at higher rates than other Americans. Researchers want to understand why. Objective: This natural history study will look at how genetic, environmental, and social factors may predict or affect COVID-19 in African Americans. Information from this study will be combined with data from the GENE-FORECAST study. Eligibility: African Americans who were previously enrolled in GENE-FORECAST. Design: The study includes a telephone interview and 1 visit to the NIH clinic. Participants may engage in either one or both of these activities. The telephone interview will last 20 minutes. Participants will talk about their experiences during the COVID-19 pandemic. The clinic visit will last up to 4 hours. Participants will have a physical exam. They will have blood and urine tests. They will be tested for COVID-19. A long swab will be inserted into a nostril to get a fluid sample from the back of the nose. They will have noninvasive tests of their blood vessels. One device used is a pen-like probe placed lightly on the wrist. Another is a rubber sleeve placed around a finger while a blood pressure cuff is used on the arm. Participants will have a test to measure the electrical activity in their heart. Stickers attached to wires will be placed on their chest, arms, and legs. Participants will answer more questions about COVID-19. They will talk about their health behavior. They will talk about their family's health and the neighborhood they live in. Other questions will ask how they feel, live, work, and play.
