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.
8-week study using stannous fluoride toothpaste on subjects with gingivitis ("unhealthy") and without gingivitis ("healthy"). Gingivitis index will be performed at BL, Week 4 and Week 8. A number of biological samples will be collected at each timepoint.
Experienced soft contact lens wearing subjects will be enrolled in this 1-week, confirmatory, randomized, bilateral, 2-way crossover, double masked (subject and investigator), repeated measures, dispensing study. All subjects will be seen for a Screening/Dispensing Visit at which informed consent will be obtained and eligibility will be assessed. If subjects satisfy all eligibility criteria and none of the exclusion criteria, subjects will be fit and dispensed study lenses according to unique randomization schedules that will be provided to each Investigator If vision is unsatisfactory in the original dispensed lenses, additional lens powers may be trialed.
A Phase 3, randomized, active-controlled, study in pediatric subjects. It is designed to evaluate the safety and anesthetic efficacy of one dose of AG-920 ophthalmic solution compared to Proparacaine Hydrochloride Ophthalmic Solution.
This project aims to improve the health of individuals engaged in co-occurring alcohol and opioid use by supporting the maintenance of behavior change initiated in substance use treatment. Building on prior research, this study will entail a stage 1b pilot to test the feasibility and acceptability of an app-based intervention for individuals reporting co-occurring alcohol and opioid use. The intervention will involve modifying an app currently used in a research study to collect GPS information to send push notifications when individuals encounter self-identified place-based triggers. Thirty individuals completing substance use treatment will consent to use the app for a thirty-day pilot period and will complete assessments of intervention feasibility and acceptability. Using within-subject tests, the analysis will summarize participant responses to assessments and will compare the use of general messaging to place-specific messaging.
In this clinical research study, subjects will be given the study drug, ACER-801 (osanetant) or placebo (looks like the study drug but contains no active ingredients). The study drug works on a receptor in the brain and the intended purpose is for the study treatment of moderate to severe Vasomotor Symptoms (VMS) also referred to as hot flashes or flushes associated with menopause. Hot flashes are a change in your temperature that occurs due to changes in your hormones.
The study is designed to characterize the safety and tolerability of VLX-1005 and argatroban administered intravenously, either alone or in combination; and the pharmacokinetics and pharmacodynamics and potential interaction of both agents in a population of healthy subjects.
This US study will evaluate the safety and effectiveness of utilizing insulin Lyumjev® lispro-aabc in the MiniMed™ 780G System in Type 1 adult and pediatric subjects in a home setting to support product and system labeling.
The purpose of this study is to evaluate the safety, tolerability, and PK of single and multiple ascending doses of VX-840 in healthy participants.
The CLARITY Study is a prospective, single-arm, multicenter safety and efficacy study of the Neurent Medical NEUROMARK System in subjects with chronic rhinitis.
There is an urgent clinical need to improve survival and neurologic outcomes after cardiac arrest. When a patient goes into cardiac arrest, cardiopulmonary resuscitation (CPR) with chest compressions is the current standard of care treatment to mechanically circulate blood through the patient's body. The immediate and long-term success of CPR is critically dependent on the maintenance of adequate coronary and cerebral perfusion. The investigators propose that CPR outcomes can be improved by capitalizing on the innate mechanism of vasoconstriction and preferentially routing the limited oxygenated blood to the heart and brain. The proposed solution is occlusion of extremity vasculature will increase coronary and cerebral perfusion and improve patient outcomes after cardiac arrest. Prior research has investigated the efficacy of manipulating peripheral vascular resistance with tourniquets in animal studies with improved cardiac and cerebral perfusion and survival. To prove this is an adequate solution in humans, the investigators plan to use tourniquets on the legs to occlude the peripheral vasculature in healthy humans and measure more proximal blood pressure before and after tourniquet deployment. Proof of concept of this solution will make way for development of novel devices for use during cardiac arrest and CPR to improve heart and brain perfusion and ultimately improve cardiac arrest outcomes. The investigators will recruit 30 healthy human participants and measure their blood pressure in their arm. They will then place two commercially-available, FDA-approved tourniquets around each thigh to stop blood flow to the legs. The investigators will measure the blood pressure in the arms again. They will then release the tourniquets after blood pressure measurement. This will be repeated three times with breaks between each repetition.
