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.
The purpose of this study is to evaluate if BrainPhyt, a microalgae based ingredient may affect cognitive function parameters in older healthy individuals with evidence of age-related cognitive decline. In a double blind, randomized manner, 40 free living males and females between 55 to 75 years with age-associated memory decline will ingest Brainphyt supplement or Placebo for 12 weeks. Cognitive function battery will be realized after 4 and 12 weeks of supplementation.
The objective of this study is to compare the safety and efficacy of OK-101 Ophthalmic Solution to placebo for the treatment of the signs and symptoms of dry eye.
The purpose of this study is to evaluate the long-term safety of the IC-8 Apthera intraocular lens (IOL).
The goal of this interventional study is to compare at-home mobile spirometry to in-clinic spirometry in participants with moderate asthma while taking a long-acting beta agonist (LABA). The main questions it aims to answer are: - Do at-home mobile spirometry and in-clinic spirometry assessments show a similar treatment effect (measured changes in FEV1) with the addition of LABA? - Is at-home mobile spirometry as accurate as in-clinic spirometry in showing treatment effects (changes in FEV1)? Participants will be asked to: - Take standard of care LABA treatment once or twice a day - Complete at-home mobile spirometry testing twice a day - Complete asthma questionnaires twice a day - Complete device use questionnaires - Wear a wrist device (like a watch) to track physical activity and vital signs - Visit the clinic for in-clinic spirometry testing once a week for 8 weeks
The purpose of this research study is to compare responses in children during dental injections of local anesthetic (used for numbing), while children are under deep sedation (breathing on their own, often with a loss of consciousness). Two types of local anesthetic will be used--one will be buffered (by adding a salt solution to make it less acidic), while the other will be plain, without anything added. Previous studies have shown that the addition of the buffer solution can improve comfort during a dental injection.
The main purpose of this study is to is to look at how much LY3437943 gets into the bloodstream and how long the body takes to get rid of it in healthy male participants. This study will involve a single dose of 14C radiolabeled LY3437943. his means that a radioactive tracer substance, C14, will be incorporated into the study drug to investigate the study drug and its breakdown products and to find out how much of these pass from blood into urine, feces and expired air. The study will last up to approximately 15 weeks including the screening period of 28 days.
The purpose of this research is to examine the potential for a new software-based behavioral support approach, for individuals with opioid use disorder, as an addition to usual care.
The purpose of this study is to test whether an over-the-counter ketone ester drink is well tolerated in people with heart failure on, and not on, a heart failure medication class called SGLT2 inhibitors. The research team is trying to determine the safest dose of Delta G. The study has a single visit. Participants will be served a light breakfast with the study drink, a physical exam will be conducted, and the study team will obtain information about demographics and medical history. The study team will draw blood intravenously up to eight times over the course of the half-day visit.
This is an implementation science study that examines implementation of a single intervention and the development of practice-level implementation strategies to facilitate implementation of the intervention.
The purpose of this study is to assess the relative effectiveness of oral (mouth) care regimens for the avoidance and treatment of plaque and gingivitis.
