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 test feasibility of a comparative effectiveness framework for acute stroke imaging using prospective electronic health data. This is a prospective, cohort feasibility study of patients presenting to the Emergency Department with suspected acute ischemic stroke. The clinical stroke team will not be blinded to the imaging modality given the nature and purpose of the interventions/imaging. Knowledge of the imaging modality used and the knowledge gained from the resulting data will need to be considered for treatment decisions. Blinding will be maintained for data abstraction and analyses. Analysis will be on an "intent-to-scan" basis and all qualifying patients will be included in their assigned cohort.
This study if for people who have been diagnosed with multiple myeloma and their doctors are recommending radiation to help treat it. Typically, radiation consists of 2-3 weeks of external beam radiation therapy. Doctors leading this study would like to see if a shorter radiation course (i.e., hypofractionation) for pelvic radiation is safe for multiple myeloma. Because participants in this study will receive a shortened radiation course, each daily treatment dose that is delivered would be slightly higher than normal. This higher daily dose would be delivered because the study team would like to see if higher doses of radiation are as safe given over a shorter number of days compared to 2-3 weeks. The purpose of this study is to make sure that hypofractionation is safe and effective for individuals with multiple myeloma.
This study will demonstrate that tarcocimab 5 mg is superior to sham treatment in participants with moderately severe to severe NPDR.
This is a multicenter, prospective, observational Phase 4 study in the United States. The study is designed to collect both medical history and prospective data on Duchenne muscular dystrophy (DMD) treatment outcomes in participants receiving delandistrogene moxeparvovec as part of clinical care, compared to participants with DMD receiving or prescribed to start chronic glucocorticoid treatment at baseline in routine clinical practice. In addition, treatment outcomes will be collected prospectively from post-trial participants who have received delandistrogene moxeparvovec through participation in select SRP-9001 studies.
This is a Phase 1a/1b, dose-escalation/expansion, consecutive-cohort, open-label study to evaluate the safety, tolerability, PK, PD, and preliminary evidence of antitumor activity of PLN-101095 in combination with pembrolizumab (the study treatment regimen) in adult participants with advanced or metastatic solid tumors for which pembrolizumab is indicated but have documented disease progression (refractory [primary resistance]) or relapsed [secondary resistance]) after at least 3 months from the start of treatment with pembrolizumab. The study will consist of 2 main parts: - Part 1: Consecutive dose-escalation cohorts using a Bayesian optimal interval (BOIN) dose escalation design - Part 2: Dose-expansion cohorts using Simon's 2-stage design
This is a supplement study being conducted to find out if collision sport athletes who are exposed to repetitive head impacts while supplementing with carotenoids will have decreased pro-inflammatory blood biomarkers, increases in macular pigment optical density, improved contrast sensitivity, greater retinal nerve fiber thickness, and better overall visual quality of life scores compared to collision athletes taking a placebo.
This study aims to advance the scientific understanding and potential future implementation of physical activity promotion by testing the efficacy of a phone-based app for increasing activity in insufficiently active patients with multiple sclerosis (MS).
A phase I clinical research study aimed at determining mechanisms that regulate airway mucosal inflammation in asthma endotypes using intranasal administration of endotoxin (lipopolysaccharide from E. coli) in healthy controls and subjects diagnosed with asthma.
The aim of this study is to investigate different formulations of S-337395.
This is an open-label multi-center study to evaluate safety and biomarkers of efficacy of a single dose of intravenously-administered AMT-191. The study will also include exploratory functional efficacy assessments. The plan is to investigate 2 sequential dose cohorts in 3-6 Participants per cohort. Participants will be monitored for 24 hours following AMT-191 administration then follow-up study visits will continue for 24 months, during which safety, pharmacokinetics/pharmacodynamics, biomarkers, and efficacy assessments will be performed. Participants will continue receiving their regularly scheduled enzyme replacement therapy (ERT) until they meet the criteria for withdrawal.
