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.
As the COVID-19 pandemic persists, a sizable proportion of the U.S. population remains unvaccinated and at high risk of death and serious illness from COVID-19. Vaccine hesitancy, fueled by the proliferation of vaccine misinformation on social media, is one factor contributing to lack of vaccination. Current attempts to overcome vaccine misinformation focus on correcting or debunking falsehoods. Although debunking strategies are important components to any public health campaign, communications must also address rationales for vaccine hesitancy that vary among individuals and communities, and directly address the gist of their concerns in an empathetic, non-judgmental manner. We will conduct a randomized controlled trial to test the effectiveness of empathic, relationship-building interactions relative to standard provision of information on social media to address COVID-19 vaccine hesitancy.
The purpose of this pilot study is to demonstrate the safety and feasibility of administering intermittent doses of Dasatinib and Quercetin (D+Q) in older adults at risk of Alzheimer's disease (AD). The study will evaluate whether giving D+Q may improve cerebral blood flow regulation, mobility, and cognition in older adults, and thus may prevent progression to Alzheimer's disease.
This is a randomized, controlled pilot trial of Behavioral Family Systems Therapy for Teens with Type 2 Diabetes (BFST-DM2), an individual psychological intervention tailored to meet the needs of teens with type 2 diabetes. It is hypothesized that this behavioral family intervention will be feasible to implement with teens with type 2 diabetes and will have positive effects on treatment adherence, health outcomes like weight status and metabolic control, and psychological outcomes.
This Phase I clinical trial will evaluate the safety, tolerability, and immunogenicity of 4 mg doses of ITI-3000 in participants with polyomavirus-positive Merkel cell carcinoma (MCC).
Way to Drive is a smart phone-based driving telematics application. Research participants are invited to download the app, which uses phone sensors to track driving behaviors including mileage, hard breaking events, and handheld phone use while driving, measured as the phone screen being unlocked while the phone is in the hand and the vehicle is in motion. Before the study team launches a clinical trial using the app, the researchers will test its capabilities and reliability.
The purpose of this study is to document the efficacy of a 3 day intermittent fasting/caloric restriction (IF/CR) using the Plexus® 3 day reset program on body weight as well as regulatory parameters of metabolism and metabolic flexibility. This study will provide data on the acute efficacy regarding the program but also identify the potential underlying physiological mechanisms through which the dietary intervention may elicit improvements, and the participant experience of the program. Collectively, this will provide a window into the possible adaptations with a longer-term dietary intervention.
Dose-ranging, randomized, double-blind, vehicle-controlled study
As part of Phase II of the NIH SBIR grant, the study will conduct a randomized controlled clinical trial in which the MapHabit system's gamification is investigated to determine whether the assistive technology facilitates user engagement and retention. Additionally, the study will examine if the gamified software improves the quality of life of persons with dementia and reduce the burden of the respective care partners. Participants will be individuals with Alzheimer's disease or related dementias in mild to moderate stage of cognitive impairment, in tandem with their respective care partner (i.e., primary familial caregiver). The study will be a randomized controlled clinical trial, in which three conditions will be investigated: 1) experimental condition in which MHS+G is implemented into the daily care received by participants 2) control condition in which the MHS alone is incorporated into the participant's daily care 3) exploratory condition where virtual reality gamification is incorporated into the MHS+G experience. The sample size will be a total of 40 individual-caregiver dyads, 20 in each condition-5 of the 20 subjects in the experimental condition will be included in exploratory condition. The study duration will be a 6-month intervention.
This is a Phase 2, randomized, multi-center study in approximately 300 adults who received 2 doses of aH5N1c or placebo in and completed the parent study V89_18 in the <65 years of age cohort. The study investigates whether two priming doses of MF59-adjuvanted H5N1 cell culture-derived vaccine (aH5N1c) followed by one or two booster vaccinations with a MF59-adjuvanted H5N6 cell culture derived vaccine (aH5N6c) 3 weeks apart elicit immune responses to the antigens used for priming (H5N1) and boosting (H5N6) after first and second heterologous booster vaccination. Eligible subjects, who received 2 doses of aH5N1c in the parent study V89_18 are randomized in a 1:1 ratio to receive either two aH5N6c vaccinations, 3 weeks apart (group 1) or an aH5N6c vaccination on Day 1 and saline placebo on Day 22 (group 2). Eligible subjects, who received placebo in the parent study will receive two aH5N6c vaccinations, 3 weeks apart (group 3). After the second vaccine administration, subjects are monitored for approximately 6 months for safety and antibody persistence. The total study duration will be approximately 7 months per subject.
The method comparison study involves capillary fingerstick blood, venous serum, and venous K2EDTA blood sample collection from human subjects receiving clozapine treatment and their clozapine concentration measurement using a validated mass spectrometry method, the automated immunoassay MyCare Psychiatry Clozapine Assay Kit manufactured by SBI, and the point of care MyCare Insite Clozapine Test manufactured by SBI. Clozapine measurements obtained using the MyCare Insite Clozapine Test are intended for investigational purposes only and shall not be used in the management of patients receiving clozapine therapy.
