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 clinical trial is a prospective study of radiosurgery treatment for progressive GBM to test 1)the efficacy of radiosurgery for recurrent/progressive GBM compared to chemotherapy , and 2) the role of diffusion-weighted image (DWI) to predict the early tumor progression and treatment response.
This is a parallel, Phase 1, four arm, open-label, single dose, multicenter study to evaluate the impact of hepatic impairment on venglustat exposure following treatment with venglustat. The purpose of this study is to assess the effect of mild, moderate, and severe hepatic impairment on PK, safety, and tolerability of venglustat compared with normal hepatic function in male and female participants aged 18 to 79 years. Study details include: - The total study duration per participant will be up to 42 days, including up to 21 days for screening and approximately 21 days from institutionalization to the end of study (EOS). - Institutionalization is mandatory until the activities on D5 have been completed. - Each participant will receive a single dose of venglustat. - For hepatically impaired participants there will be a screening visit, a multi-day institutionalization visit, and 7 site visits after D5 discharge, including the end of study (EOS) visit. - For healthy volunteers there will be a screening visit, a multi-day institutionalization visit and 3 site visits after D5 discharge, including the end of study (EOS) visit.
This study creates a patient registry of patients undergoing contrast-enhances-harmonic endoscopic ultrasound imaging. In order to improve what doctors see on the ultrasound exam, sometimes intravenous contrast can be used to better emphasize the blood flow in a particular organ or lesion. Creating a local database that can be used as a patients registry may help doctors keep track of all patients that undergo contrast-enhanced endoscopic ultrasound procedures and also to monitor for possible procedure adverse events.
Since 2005, FDA has required almost all new drugs be tested for their ability to prolong the QT interval through clinical studies. This requirement stems from the increased TdP risk QT interval prolongation can cause. However, the QT interval is an imperfect biomarker, as there are multiple drugs that can prolong the QT interval, without causing increased TdP occurrence. As such, numerous drugs labeled as causing QT prolongation, may in fact have no impact on TdP occurrence. To address this problem, FDA, in collaboration with multiple external partners, has led an initiative to combine novel preclinical in vitro experiments within silico modeling and simulation followed by pharmacodynamic electrocardiographic (ECG) biomarkers. The goal is to use these novel computational and analytical tools to better predict TdP risk (beyond just the QT interval) by focusing on understanding the underlying mechanisms and applying an integrated biological systems approach. This clinical study consists of 2 parts: a 3-arm, 22-subject crossover study (Part 1) and a 4-arm, 22-subject crossover study (Part 2). These parts are included in the same protocol and study due to the similarity of the inclusion and exclusion criteria, similar procedures, and similar primary goals.
The goal of this clinical study is to test if obeldesivir (formerly GS-5245) is safe and effective for the treatment of coronavirus disease 2019 (COVID-19) in participants who have a standard risk of developing severe illness. This study will also measure how much obeldesivir gets into the blood and how long it takes for the body to get rid of it.
This study is designed as an international prospective, multicentric, clinical study to investigate the performance and usability of the Panbio™ COVID-19/Flu A&B Rapid Panel Professional Use and Self- Test devices for the qualitative detection of COVID-19 antigen, Influenza A antigen and Influenza B antigen in human nasopharyngeal (NP) and mid-turbinate nasal swabs, respectively. This study is part of the performance evaluation to support the CE conformity assessment procedures.
Phase 1/2a, multicenter, randomized, vehicle-controlled, double-masked, multiple-dose, parallel-group study conducted in adult subjects with acquired blepharoptosis.
The goal of this pilot trial is to learn about the optimal intensity level of goals in a digital weight loss intervention among adults with overweight or obesity. The main questions of the study are to assess the feasibility and acceptability of different goal intensities across four domains (calorie goal, step goal, eating window goal, red zone food goal). The investigators will recruit 32 total participants to the trial. Recruitment will occur through remote channels. Interested individuals will be directed to an online screening questionnaire; those who are eligible will then be invited to attend an initial remote session with study personnel to ensure interest and eligibility in the study. The weight loss intervention will last 10 weeks, and all participants will receive a "core" treatment consisting of self-monitoring weight, food intake, and steps (all via digital tools provided by the study team), along with behavioral lessons, action plans, and tailored feedback. Depending on which group participants are assigned to in the study, individuals will receive either a more or less challenging goal across the four domains. All study tasks will occur remotely, thus, participants will never come in-person for any tasks. Assessment of body weight and other measures will occur at the beginning of the trial ("baseline"), and at 4 weeks and 10 weeks. The investigators will use the Multiphase Optimization Strategy (MOST) framework to identify which of the goal intensity levels result in meaningful engagement and weight loss. The current study is the first step towards answering this question; it is designed as a pilot factorial trial, which focuses on feasibility and acceptability. In total, there will be 16 treatment conditions.
To determine if there is any carry over effect of sensation training for the feet, officially called Graded Motor Imagery (GMI), will impact balance and fall risk factors in older individuals. This will be looked at to see if there is a difference in balance and sensation before and right after the training.
The goal of this randomized, placebo-controlled, three-condition, double-blind, within-participants crossover clinical trial is to compare caffeine, TeaCrine plus caffeine, and a placebo condition in ROTC or tactical personnel. The main question it aims to answer is the effect of the condition on measures of cognitive performance, cardio-autonomic, and hemodynamic responses after a physically demanding protocol. The physiological function will be derived from metrics of heart rate variability, whilst cogntive performance will be evaluated using tasks that assess cognitive domains of executive function, reaction time, and memory. Participants will report to the lab 4 times, once for familiarization of cognitive measures and then 3 times for their experimental visits. Participants will consume their randomized condition an hour prior to the fatiguing interval exercise protocol. Following they will complete a series of cognitive tasks.
