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-center, open-label, 6-month study to evaluate the safety of bilateral CNTF implants in participants with Macular Telangiectasia Type 2.
Aim: To test the effects of a fiber-blend containing snack prototype in an escalating dose regimen (from 1 to 3 servings per day over a period of 6 weeks) on the configuration and gene content of the gut microbiota of overweight and obese participants (BMI 25-35 kg/m2), while consuming a controlled diet that contains quantities of saturated fats in the upper tertile and quantities of fruits and vegetables in the lower tertile of consumption in the NHANES database (high saturated fat-low fruit and vegetable; HiSF-LoFV). Changes in the representation of bacterial genes involved in carbohydrate utilization in the microbiomes of participants will be correlated with changes in plasma biomarkers at the end of each escalating dose phase by comparing features of their pre- vs post-treatment plasma proteomes and metabolomes. Design: Participants will be asked to continue to consume their habitual diet (free diet phase) for 1 day prior to being provided with a HiSF-LoFV diet in the form of packed-out meals and snacks to consume for the following 62 days. Ten days after starting to consume the HiSF-LoFV diet, participants will supplement this diet with a fiber-blend containing snack (~10g fiber/serving) once daily for a total of 14 days; the energy contribution from the HiSF-LoFV diet will be reduced accordingly to maintain energy needs during this time and the remainder of the study. For the next 14 days, the diet will be supplemented with two of the same fiber-blend containing snacks per day, followed by 14 days in which the snacks will be consumed three times daily. Subsequently, a 'wash-out' phase of ten days in which the HiSF-LoFV diet is consumed without any of fiber snack supplementation will conclude the study. Stool, urine and blood will be sampled periodically throughout.
This study involves completing some online assessments and an intervention for social anxiety that all involve interactions with other people on a teleconferencing call.
The purpose of this study is to demonstrate similar efficacy and safety between TVB-009 and Prolia® (denosumab)
This study aims to expand the normative dataset for Philips IntelliSpace Cognition to include ages 18-49 and 80+ and aims to validate two new digital tests.
Our pilot study will address a number of pressing questions, including: Can community clinicians successfully coach parents of children with ASD in evidence-based practice to achieve positive outcomes for their children and themselves? What dose is necessary to achieve change? And what is the cost effectiveness of implementing evidence-based interventions at different doses?
To evaluate the pharmacokinetics (PK) and pharmacodynamics (PD) of vonoprazan (20 mg) and lansoprazole (30 mg) following single (Day 1) and multiple doses (Day 7).
The mortality rates associated with COVID-19 related ARDS (COVIDARDS) have varied from observational reports from around the world. This has ranged from 44% (28 day mortality) in the UK to 36% (28 day mortality from ICU admission) in Italian studies, to 32% (all-cause 28 day mortality) in Spain. Predictive models have identified risk factors for COVID-19 hospitalized patients' mortality to include male sex, obesity, age, obesity, comorbidities including chronic lung disease and hypertension, as well as biomarkers including high levels of D-Dimer, LDH and CRP. In addition, practice patterns, such as drugs that were administered, timing of mechanical ventilation and adherence to established lung protective ventilation protocols are known to be variable across sites and have changed over time. The investigators propose to analyze outcomes for patients with COVIDARDS within the NorthCARDS dataset (a dataset of over 1500 patients with COVID-19 related ARDS across the Northwell Health System in the NYC metropolitan region and Long Island, NY) to understand differences in hospital survival and in the time to liberation from mechanical ventilation, specifically looking at the associations between baseline patient factors, changes in biomarkers, respiratory function and hemodynamics over time, and treatments administered. The analyses will be based on three hypotheses: H.1. Worsening trajectories of: oxygenation index (OI), respiratory system compliance (C), and inflammatory markers will be associated with lower hospital survival. H.2. Higher duration of deep sedation and paralytics will be associated with greater time to liberation from mechanical ventilation. This risk will be increased in patients with worsening trajectories of OI, C, and inflammatory markers over time. H.3. Type of mechanical ventilator, specifically the time on portable mechanical ventilator, is associated with hospital mortality and with inability to liberate from mechanical ventilator despite controlling for risk factors of changes in OI, C and Inflammatory markers over time, and the use of paralytics and deep sedation.
The purpose of the study is to improve the quality of future clinical trials in bullous pemphigoid (BP), the investigators will monitor repeated measurement data from patients with BP on standard-of-care treatments at four week intervals for four months.
Suicide is the 2nd leading cause of death among college students and suicidal ideation and suicide-related behaviors are a frequent presenting problem at college counseling centers (CCCs), which are overburdened. Studies show that some students respond rapidly to treatment, whereas others require considerably more resources. Evidence-based adaptive treatment strategies (ATSs) are needed to address this heterogeneity in responsivity and complexity. ATSs individualize treatment via decision rules specifying how the type and intensity of an intervention can be sequenced based on risk factors, response, or compliance. The purpose of this multisite study is to investigate the effectiveness of four adaptive treatment strategies (ATSs) to treat college students who report suicidal ideation when first seeking services at their college counseling center This multisite study will enroll moderately to severely suicidal college students in the "emerging adulthood" phase (ages 18-25) seeking services at CCCs. This Sequential Multi-Assignment Randomized Trial (SMART) will have two stages of intervention. In Stage 1, 700 participants from four CCCs will be randomized to 4-8 weeks of: 1) a suicide-focused treatment - Collaborative Assessment and Management of Suicidality (CAMS) or 2) Treatment as Usual (TAU). Sufficient responders to either intervention will discontinue services/be stepped down. Non-responders will be re-randomized to one of two Stage 2 higher intensity/dosage intervention options for an additional 4-16 weeks: 1) CAMS (either continued or administered for the first time) or 2) Comprehensive Dialectical Behavior Therapy (DBT), which includes individual therapy, skills group, and phone/text coaching for the clients and peer consultation for the counselors.
