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 pilot study evaluating the feasibility of daily online adaptive planning for patients undergoing proton radiation therapy. Patients undergoing proton radiation therapy normally undergo extensive pre-planning for their treatment. However, accounting for uncertainties in treatment delivery remains a challenge for a variety of reasons, such as differences in patient anatomy from pre-planning to the day of treatment. Online adaptive planning is a process consisting of generating the original pre-plan on the patient on a treatment day, assessing the pre-plan's coverage and safety, and if changes are needed, the plan is changed in order to optimize the treatment while the patient is still on the treatment table. This study is assessing the feasibility and safety of this approach in order to gather data for a larger trial.
A field-based trial was conducted to determine if oral prochlorperazine demonstrates efficacy in the prophylactic treatment of AMS, and/or decreases the incidence of the symptoms of acute mountain sickness including headache, GI symptoms, fatigue and dizziness based on data collected in the Lake Louise AMS score.
This study aims to assess any impact of VH4524184 on the pharmacokinetic (PK) profile of an ethinyl estradiol (EE) and norethindrone acetate (NEA) containing oral contraceptive (OC) administered to healthy adult female participants.
The goal of this clinical trial is to learn about, test, and compare health outcomes of high vs. low-processed feeding. The main question[s] it aims to answer are: • Does consuming a diet rich in unprocessed food improve various health outcomes? Participants will either be instructed to consume a diet rich in unprocessed food for 6 months, or consume their typical diet for 6 months. At various points in the study there will be metabolic health data collected. If there is a comparison group: Researchers will compare the low-processed group to the typical diet group to see if there are improvements in metabolic health.
The purpose of this study is to identify 1 or more doses of parenterally administered VH4524184 that are safe, well tolerated and yield a PK drug exposure profile necessary to deliver a long-acting antiretroviral therapy for the treatment of HIV-1 infection.
This study is conducted to determine the Relative Bioavailability of Ruxolitinib XR Tablets Compared With Ruxolitinib IR Tablets Administered Orally in Healthy Participants.
The investigators will accomplish our research aims by collecting cutaneous microbiome samples from 50 persons that have undergone the Osseointegration (OI) surgery at eight timepoints, prospectively. The investigators will also collect control samples to correct for turnovers in species compositions that may naturally occur and to compare the residual limb microbiome to the sound contralateral limb. The investigators will sequence the bacterial community using universal bacterial primers. Using these sequences, The investigators will borrow from ecological theory and calculate the alpha and beta diversity. The alpha diversity will determine the species and abundance of each species that are present, while the beata diversity will allow us to compare how species assemblages and frequencies change between time points. Then, the investigators will take a phylogenetic modeling approach to determine if particular species assemblages correlate with rates of wound healing. The investigators will construct phylogenies from the sequences at the different time points and "paint" the rate of wound healing along the phylogeny (e.g., improved, stagnated, worsened). Using Akaike and Bayesian information criterion, the investigators can determine which phylogenetic model best explains the patterns the investigators see across patients. Lastly, the investigators will quantify soft tissue stability and health and correlate this with the homeostasis of the microbial community. Specifically, the investigators will determine if redundant soft tissue leads to altered microbial communities that can impact the rate of wound healing. Finally, the investigators will further stratify these data to compare microbial communities between the sexes, upper versus lower limbs, and proximal versus distal amputations. This work will allow us to better treat infections after OI surgery and can shed light on wound healing process so that the investigators can better treat limb loss patients and the military community as a whole.
Chronic low back pain (CLBP) is a debilitating condition and costly to treat. Long-term drug treatment often fails due to habituation, breakthrough of pain, or adverse effects of drug treatment. Opioid use to manage this pain has contributed to the opioid epidemic. Spinal cord stimulators have emerged as a promising treatment and reduces reliance on drugs. However, response to spinal cord stimulation (SCS) is unpredictable. It is difficult to predict which patients will respond positively to SCS because the physiological mechanism for treatment responsiveness is unclear. Therefore, the aim of this study is to investigate how spinal cord stimulators affect functional measures in patients with CLBP, including functional MRI, neurophysiology, gait analysis, and questionnaires. The results of this study can lead to the widespread adoption of spinal cord stimulators as a safe and effective therapy for CLBP, reducing the reliance on opioids and mitigating the opioid epidemic's impact.
The goal of this clinical trial is to test a modified smart soft contact lens in neonates and infants at risk of developing hydrocephalus. The main questions it aims to answer are: - Can the device distinguish between intracranial pressure variations in neonates and infants diagnosed with hydrocephalus and those without - Can the device compare pressure dynamics between pre- and post-operative periods in neonates and infants who undergo surgical treatments Participants will undergo standard of care evaluations for hydrocephalus (anterior fontanelle assessment and head circumference measurement) and wear the device during standard of care evaluation; pre- and post- ventricular reservoir taps, as applicable; and/or pre- and post-operatively, as applicable.
The purpose of this study is to assess user satisfaction and the frequency of common central venous catheter insertion complications when using a novel cannulation knife.
