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.
Idiopathic Pulmonary Fibrosis (IPF) is a chronic progressive fibrotic lung disease resulting in increasing shortness of breath, cough, and low oxygen levels as a result of lung tissue scarring . The goal of this open-label (no placebo) study is to evaluate the safety and tolerability of artesunate at three different doses in patients with IPF. The secondary goals are to explore the blood biomarkers present in IPF patients at the beginning of the study and to study how those biomarkers change following treatment with artesunate. Participants will have 7 visits to the study site over 20 weeks which will include physician exams, vital signs, questionnaires, research and safety blood samples, and taking artesunate capsules by mouth for 12 weeks. Artesunate is used world-wide for the treatment of severe malaria but has also been found to block specific proteins that cause lung scarring and may provide an additional treatment to slow the fibrotic process in the lung and improve survival and quality of life for patients with IPF.
This is a Prospective, controlled, single-blind, randomized (2:1, Intervention:Control) clinical trial. The purpose of the study is to determine the role of adjunctive renal sympathetic denervation in the prevention of Atrial Fibrillation (AF) recurrence in patients with hypertension scheduled for a redo AF ablation procedure for paroxysmal or persistent AF. Patients will be randomized to either i) AF ablation (Control) or ii) AF ablation + renal sympathetic denervation (Intervention).
The overall goal of the 5-year project is to conduct both a process and rigorous outcome evaluation of The Set Me Free Projects (SMFP) READY to Stand (RTS) curriculum with an eye toward widespread dissemination to other U.S. communities, if deemed effective.
The Effects of Successful OSA TreatmENT on Memory and AD BIomarkers in Older AduLts (ESSENTIAL) study is a 5-year, multicenter randomized open-label trial that will screen 400 cognitively normal older adults recruited from well-established sleep clinics at 4 academic medical centers, with newly diagnosed moderate-severe OSA. An expected 200 OSA patients will be then randomized to one of two groups: i) a 3-month OSA treatment by any combination of PAP, OAT, and positional therapy that results in an "effective" AHI4%< 10/hour and AHI3A<20/hour (see below); ii) a waitlist control group to receive treatment at the conclusion of the 3-month intervention period. Both groups will continue follow-up for 24 months on stable therapy to determine if sustained improvements in sleep are associated with improvement in cognitive function and AD biomarkers.
The investigators will test the impact of a package of linguistically appropriate discharge teaching tools against current standard of care for patients with Limited English proficiency (LEP) in an unblinded randomized controlled trial. The tools include an expanded medication calendar in English and the patients' preferred language, pictographics to illustrate return precautions (what signs/symptoms require further evaluation), an audio recording of the nurse reviewing the After Visit Summary (composed by providers) to allow for review by patients and caretakers after discharge. The investigators will evaluate the effectiveness of the package of discharge teaching tools on patients' understanding/recall, key implementation outcomes, and secondary clinical outcomes via a structured interview 1-2 weeks after discharge and chart review 30 days after discharge. The objectives of this research study are: 1. test the effectiveness of a linguistically appropriate toolkit for improving patient understanding of discharge instruction content 2. Assess the feasibility and fidelity of the intervention in anticipation of a multi-site implementation trial 3. assess the feasibility and appropriateness of the linguistically appropriate toolkit to nurses and in-person interpreters 4. to assess the acceptability of the intervention to patients and their satisfaction with it 5. to collect data on implementation context in anticipation for a multi-site trial 6. to collect preliminary data on the toolkit's impact on clinical outcomes including medication adherence and hospital re-utilization.
This is a dose-escalation, Phase I/II trial evaluating the safety, tolerability, reactogenicity and immunogenicity of the investigational RNA-based multivalent vaccine candidate BNT166a for active immunization against monkeypox (mpox). This trial will start with the two substudies, i.e., substudy A (SSA) and substudy B (SSB). This trial will be initiated with the dose-escalation SSA. In substudy A and substudy B, dosing will start with an initial sentinel group, followed by the expansion cohort. This study was initially planned to investigate two vaccine candidates (the quadrivalent BNT166a and the trivalent BNT166c). The sponsor decided to not activate the groups with BNT166c.
This trial will test the effects of a positive emotion-focused preventive intervention on reward responsiveness in children of mothers with histories of depression and anhedonia.
This prospective longitudinal study will follow participants with Multifocal Motor Neuropathy over time and collect data on their clinical outcomes, quality of life, and use of health care resources. Participants will follow their regular visit schedule with their treating physician, except for an optional second visit occurring 7 to 14 days after the start of the study to collect biomarker data. No IMP will be administered.
The primary objective of this study is to evaluate the effects of therapeutic and supratherapeutic doses of avacopan on the heart rate corrected QT interval, using Fridericia's formula (QTcF).
The primary objective of this clinical trial is to evaluate the effect of a high-fat, high-calorie meal on the pharmacokinetic (PK) profile of CCX168, following oral administration of a single dose of 30 mg CCX168 to healthy volunteers.
