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.
Background: Influenza (flu) is a virus that infects people of all ages. Some people may have mild flu symptoms. Others may get very sick and even die from the flu. Flu vaccines help protect people against the flu, but if the flu strains in the vaccine are not a good match with the strains circulating in the community, the vaccine is not as effective. Researchers want to make flu vaccines that protect against changing flu strains. Objective: To test if a new flu vaccine is safe and if it creates an immune response. Eligibility: Healthy adults ages 18-55 who do not smoke and have not received a flu vaccine in the 8 weeks prior or a COVID-19 vaccine in the 4 weeks prior to enrollment. Design: Participants will be screened on a separate protocol. Participants will have 9 visits over 7 months. They will get a combination of study vaccine and/or placebo, both as a shot in the arm and as a spray into the nose, at 2 visits. For 7 days after getting the vaccines, they will take their temperature and complete online surveys at home to record any symptoms. At each visit, participants will have a physical exam and medical history. They will give blood and urine samples. They will have nasal testing. For this, a thin absorptive strip will be inserted into their nostril for 1 minute to collect mucus. At some visits, the inside of their nose will be wiped with a small brush to collect cells. For this, their nostril will be numbed to make it more comfortable. Some blood and nasal samples will be used for genetic testing. Participants who get flu-like symptoms during the study will be asked to collect nasal samples at home and send these samples back to NIH to test if they actually have the flu.
The study is designed to evaluate the BE and adhesion properties of granisetron transdermal patches manufactured at 2 different sites. The study has been designed in accordance with the FDA Guidance for Industry. Bioequivalence will be based on the Cmax and AUC to determine the peak and total drug exposure, respectively.
Approximately 9 participants will be enrolled in the study in a single cohort. Participants will be randomized to 3 g IXT-m200 or placebo at 7:2. Each will receive their dose as a 30-min intravenous infusion, then remain at the study site overnight to complete Day 1 and Day 2 assessments (e.g., electrocardiogram (ECG), laboratory assessments, blood draws, and vital signs). Following discharge on Day 2, participants will return to the clinic for follow-up pharmacokinetic (PK) and safety assessments on Day 8, then every 1-3 weeks thereafter until Day 127.
This is a prospective study of up to 30 subjects designed to assess the safety and effectiveness of a non-ablative fractional laser combination wavelength treatment for general resurfacing of photoaged skin. All study subjects will be treated on the whole face with the CLEAR + BRILLIANT TOUCH(R) 1440-nm and 1927-nm handpieces. Subjects will be treated with a consecutive series of four (4) treatments spaced 1 month apart, along with follow-up study visits at one (1) and three (3) months after final treatment.
AOC 1001-CS1 is a randomized, double-blind, placebo-controlled, Phase 1/2 study to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of single and multiple-doses of AOC 1001 Administered Intravenously to Adult Myotonic Dystrophy Type 1 (DM1) patients (MARINA). Part A is a single dose design with 1 cohort (dose level). In Part A, the patient duration is 6 months as the treatment period is 1 day followed by a 6 month follow-up period. Part B is a multiple-ascending dose design with 2 cohorts (dose levels). In Part B, the patient duration is 6 months as the treatment period is 3 months followed by a 3 month follow-up period.
In the United States, people of color (POC) are disproportionally affected by stressors related to race/ethnicity compared with their non-Latinx White (NLW). Considering POC exposed to race-related stress are at high risk of developing a mental health disorder, there is a clear need for treatments that allow individuals to cope effectively with these stressors. Among many evidence-based treatments available, mindfulness-based interventions (MBIs) may be particularly well suited to help POC cope. MBIs are hypothesized to be effective via increases in mindfulness and self-compassion, as well as reductions in experiential avoidance, rumination, and emotion suppression. Despite their effectiveness, MBIs rarely reach POC. As such, innovative strategies such as self-directed app-based intervention may reduce the treatment gap. Considering the lack of research examining the effectiveness of MBIs among POC, especially those who experience elevated levels of race-related stress, this study will employ a randomized control trial (RCT) approach to examine whether receiving an app-based MBI engages the hypothesized mechanisms of change (i.e., mindfulness, self-compassion, experiential avoidance, rumination, emotion suppression) among POC. Similarly, the study will test whether the intervention leads to decreases in the negative mental health outcomes more often associated with exposure to race-related stress (i.e., stress, anxiety, depression). Acceptability, adherence, and satisfaction also will be analyzed to explore whether a non-culturally adapted MBI is still relevant for POC who face race-related stress. Results from this trial will contribute to the nascent data on MBI acceptability and effectiveness with POC. To the investigators' knowledge, this study will also be the first to include a sample of POC recruited based on elevated levels of race-related stress, a high-risk population that is not commonly targeted in MBI research.
Postpartum hemorrhage (PPH) is the leading cause of maternal morbidity and mortality worldwide. Up to 80% of PPH is caused by uterine atony, the failure of the uterine smooth muscle to contract and compress the uterine vasculature after delivery. Laboratory and epidemiological studies show that low extracellular and serum calcium levels, respectively, decrease uterine contractility. A pilot study performed by the investigators supports the hypothesis that intravenous calcium chloride is well tolerated and may have utility in preventing uterine atony. The proposed research will establish the relationship between uterine tone and calcium through a clinical trial with an incorporated pharmacokinetic and pharmacodynamic (PK/PD) study. In a randomized, placebo-controlled, double-blind trial, investigators will establish the effect of 1 gram of intravenous calcium chloride upon quantitative blood loss and uterine tone during cesarean delivery in parturients with high risk of uterine atony. Investigators will concurrently collect serial venous blood samples to measure calcium for PK/PD modeling in this pregnant study cohort. High-quality clinical research and development of novel therapeutics to manage uterine atony are critical to reduce the high maternal morbidity and mortality from PPH.
This clinical trial examines the effects of simulated solar radiation on human skin in preventing skin cancer. Testing whether new drugs affect biomarkers in the skin is a good first test of whether the drug might prevent skin cancer. Some biomarkers in skin, and even in moles, are affected after a person is exposed to sunlight. This study may help doctors learn more about what happens to the skin and moles when the participants are exposed to the sun.
This was a Phase I, open-label, single-dose, parallel-group study in participants with mild hepatic impairment (HI) and healthy matched control participants with normal hepatic function designed to evaluate the PK of pelacarsen following a single 80 mg s.c. dose. Participants were matched by gender, age (±10 years), and body weight (±15%).
This study will examine the impact of providing patient-reported outcomes measurement information system (PROMIS) scores to patients before appointments with their healthcare provider.
