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 study will compare basic properties of gut epithelia of hypertensive and normotensive reference subjects. The study will determine if there are fundamental differences in the gut epithelium in hypertension compared to normotension.
This Parkinson disease (PD) trial will test whether 26 months of citalopram, compared to placebo, can alter the build-up of toxic amyloid-beta plaques in the visuospatial cortex of the brain linked to visuospatial cognitive impairment in PD.
The aim of this study is to determine the safety and efficacy of cabozantinib in the management of unresectable or metastatic hepatocellular carcinoma (HCC) with underlying Child-Pugh class B cirrhosis.
To determine if biomarker-based CSF testing is reliably detecting differences between patients with Multiple Sclerosis (MS), different MS-subtypes, and other central nervous system (CNS) diseases. This study will also look to identify biomarkers that could be used for the prediction, at the time of diagnosis, of the future disease clinical course and response to therapy. The SOMAscan assay will be used for CSF samples analysis.
This is a prospective, double-blind, randomized, placebo-controlled study to assess the effects of suramin as a potential treatment option to prevent subjects with AKI from progressing to Kidney Disease Improving Global Outcomes (KDIGO) Stage III or dialysis dependent AKI.
The SAFE-PAD Study aims to evaluate the long-term safety of paclitaxel-coated devices compared with non-paclitaxel-coated devices for femoropopliteal artery revascularization among a broad, real-world population of patients with peripheral artery disease. This multi-year analysis aims to create an ongoing mechanism to evaluate the safety of paclitaxel-coated devices in real world practice. The null hypothesis is that the paclitaxel-coated devices are associated with an increase in mortality relative to the non-drug-coated devices beyond an acceptable magnitude (i.e. the non-inferiority margin), and the alternative hypothesis is that paclitaxel-coated devices are not associated with an increase in mortality relative to the non-drug-coated devices beyond the non-inferiority margin.
Radioactive iodine (RAI) is a radioisotope used to ablate thyroid gland remnant after thyroidectomy in patients diagnosed with differentiated thyroid carcinoma (DTC). A whole body scan (WBS) is performed to not only evaluate for iodine uptake by the native thyroid tissue but also to observe for uptake in other areas of the body, which could be physiological or indicative of iodide-avid metastases. Research has shown a correlation between breast cancer and thyroid cancer. Patients with DTC have been found to have elevated levels of serum prolactin, which could lead to mammary gland dysfunction. In patients with DTC undergoing RAI scanning or therapy, it has been previously observed that patients prepared by thyroid hormone withdrawal have significantly higher breast uptake on whole body scan compared to those prepared by rh-TSH. Considering the impact of prolactin on breast tissue, this study aims to correlate these findings with the lab values and the method of preparation. Accordingly, the research question is as follows: does the method of WBS preparation impact prolactin levels and how does that correlate with breast uptake in patients with DTC undergoing RAI WBS?
There are an increasing number of people in the U.S. with Alzheimer's disease and other dementias. Traumatic brain injuries (TBIs) are also common among both civilians and military personnel, and TBIs increase a person's risk for dementia. Providing care for a person with dementia is stressful. Dementia caregivers can experience difficulties including stress, depression, and reduced quality of life. Coordinated dementia care is known to benefit people with dementia and their caregivers. However, many caregivers do not have access to these supportive programs. Our project studies the benefits of telehealth as a new way for caregivers to receive coordinated dementia care services. We will offer 75 caregivers a 12-month caregiver support program delivered using telehealth (for example phones, tablets, computers). Caregivers of both Alzheimer's disease and TBI-related dementia will be included, and the program will be evaluated for effectiveness in both groups as well as in a control group. The information from our study will help improve quality of life for caregivers and individuals with dementia, including military members and Veterans. Our results will also help both civilian and military health professionals develop effective programs to support families living with dementia. Policy makers and organizational leaders can use the information to fund programs that best help families and communities facing dementia and TBI dementia.
The need for improved diagnostic methods in Multiple Sclerosis (MS) is widely recognized. Although Magnetic Resonance Imaging (MRI) is a longstanding tool for detecting MS lesions, diagnostic inaccuracies persist. Up to 20% of people diagnosed with MS (1 in 5) are later found not to have the disease. This is highly consequential, as more than two-thirds of misdiagnosed patients are unnecessarily exposed to risks from disease-modifying therapies, which in rare cases can be life-threatening. Moreover, the current standard in MS diagnosis - the McDonald criteria, which combine clinical symptoms and MRI findings - were developed from studies in people with typical clinical presentations of MS. This reduces the specificity of these criteria, rendering them uninformative for the nearly half of MS patients who present to neurologists with atypical or nonclassical symptoms. Timeliness of MS diagnosis is also key, as diagnostic delay is common in cases of relapsing-remitting MS and can carry severe and lifelong consequences. The CentrAl Vein Sign in MS (CAVS-MS) study has been designed to assess whether Central Vein Sign (CVS) criteria can help address some of these unmet diagnostic needs. It will specifically explore the role of presentation type by enrolling a mixed population of patients with typical clinical presentations (n = 200) and those with atypical presentations, including suggestive MRI findings in the absence of neurologic symptoms (n = 200) across North America.
This study is a Phase 1, open-label, single institution, dose escalation and dose expansion study to evaluate the efficacy, safety, and tolerability of APX005M in combination with nivolumab and ipilimumab in patients with advanced melanoma and RCC.
