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 multi-site, open-label, 8-week, prospective observational study, conducted at multiple sites geographically dispersed within the U.S. The purpose of this Actual Use Study (AUS) is to investigate how U.S. adult tobacco consumers 21 to 60 years of age, inclusive, who typically smoke on average (≥5 cigarettes/day) on at least 20 out of the past 30 days will use a heated tobacco product comprising a heating device and four non-combusted cigarette variants (HTP Investigational Product [IP]) over a 6-week Actual Use Period (AUP) in their real-life/naturalistic environment and in the context of typical consumer marketing materials.
This pilot trial studies the effect of the microbiome on immune checkpoint inhibitors response in patients with melanoma by collecting stool and blood samples. Gut microbiome plays a critical role in response to immune checkpoint inhibitors. Studying the change in an individual's microbiome due to corticosteroid use may help researchers to determine whether an individual's microbiome can predict their response and toxicity to immune checkpoint inhibitors.
This is an open-label, single center, trial that will enroll up to 25 participants with circulatory shock after cardiac surgery. Participants will be administered a topical sublingual nitroglycerin solution and assessed for changes microcirculatory blood flow using incident dark field microscopy.
The intended use of the PicoSure and PicoSure Pro devices used in this study is to treat additional patients with the new PicoSure Pro device and collect additional data on the devices.
This clinical trial aims to assess the effect of providing one avocado per day on skin health in comparison with a control group maintaining their habitual diets. Participants will be randomly assigned to one of two equally sized groups. Both groups will be instructed to continue to follow their habitual diet but the intervention group will receive one avocado per day. Participants will be followed for outcomes for a four-month period.
This study aims to refine and evaluate feasibility of a telehealth intervention for persons with Alzheimer's disease and their caregivers. The intervention will use evidence-based techniques for decreasing symptoms of depression, anxiety, and poor sleep, that are commonly reported among this vulnerable group during the COVID-19 pandemic. Improved symptoms among this group may improve their other health outcomes and quality of life and furthermore the quality of care that caregivers provide for persons with Alzheimer's disease during this challenging time.
The purpose of this study is to assess the wear experience of existing wearers of a monthly replacement contact lens after they have been fit with a daily disposable contact lens that has water surface treatment.
This pilot study aims to replicate results of a previously studied novel, non-pharmacological psychosocial intervention for children with ADHD, utilizing an Animal Assisted Intervention with therapy dogs combined with traditional social skills training (AAI) compared to psychosocial treatment as usual with social skills training alone (TAU). This study also aims to determine if candidate physiological markers of HPA axis and ANS activity differ between groups and if these markers moderate response to the interventions.
The purpose of the HD-SLEEP2 study is to help researchers understand sleep in African Americans. The investigators also want to know what factors may affect sleep.
The purpose of the HD-SLEEP1 study is to help researchers understand what African Americans know and think about sleep. The investigators also want to know how to encourage people to participate in research studies designed to improve sleep.
