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 biomarker study designed to collect and analyze blood specimens from individuals carrying known familial frontotemporal lobar degeneration (f-FTLD) mutations compared to a control group of individuals without known f-FTLD mutations. The NSP is an ancillary study to the ARTFL LEFFTDS Longitudinal Frontotemporal Lobar Degeneration" (ALLFTD) study, NCT04363684. More information can be found at https://www.allftd.org/.
This study investigates the bone-related side effects caused by immunotherapy drugs such as nivolumab and pembrolizumab in patients with melanoma. Nivolumab and pembrolizumab are immunotherapy drugs (drugs that boost your immune system) used to prevent cancer from coming back in patients with melanoma. Specifically, researchers want to learn if there is any relationship between receiving immunotherapy and bone density (thickness) measured by a dual-energy X-ray absorptiometry (DXA) scan or bone turnover markers (which indicate levels of bone loss) found in the blood. This study may provide researchers with more information on bone loss and may help prevent bone loss in future patients.
This phase II trial investigates how stereotactic radiosurgery affects brain functions while treating patients with small cell lung cancer that has spread to the brain (brain metastasis). Standard of care treatment consists of whole brain radiation therapy, which targets the entire brain, and may result in side effects affecting the nervous system. Stereotactic radiosurgery only targets areas of the brain that are suspected to be affected by the disease. The purpose of this trial is to learn if and how patients' brain functions are affected by the use of stereotactic radiosurgery rather than whole brain radiation therapy in managing brain metastasis caused by small cell lung cancer. Stereotactic radiosurgery may help patients avoid nervous system side effects caused by whole brain radiation therapy.
A prospective, open label, single-arm 90-day study designed to assess the safety, performance and efficacy of thrombus removal in subjects presenting with acute ischemic stroke with the NeVa stent retrievers.
This phase I trial investigates the side effects and best dose of BAY 1895344 when given together with usual chemotherapy (irinotecan or topotecan) in treating patients with solid tumors that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced), with a specific focus on small cell lung cancer, poorly differentiated neuroendocrine cancer, and pancreatic cancer. BAY 1895344 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Chemotherapy drugs, such as irinotecan and topotecan, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Adding BAY 1895344 to irinotecan or topotecan may help to slow the growth of tumors for longer than seen with those drugs alone.
This phase I trial investigates the side effects of cabozantinib and nivolumab in treating patients with cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) and who are undergoing treatment for human immunodeficiency virus (HIV). Cabozantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving cabozantinib and nivolumab may shrink or stabilize cancer in patients undergoing treatment for HIV.
Discrepancies exist among aortic stenosis severity classification, patient symptom burden, and - in some cases - even survival. The new Stress Aortic Valve Index (SAVI) metric correlates better with transvalvular flow and might be a better predictor of symptoms and prognosis. The current study will demonstrate the value of SAVI (both non-invasive and invasive) in patients with moderate aortic stenosis. The population will consist of subjects at least 50 years old with moderate aortic stenosis (defined as aortic valve area >1.0 cm2 plus either maximal velocity 2.5-3.9 m/s or mean gradient 15-39 mmHg). Subjects with severe concomitant valve disease or severe unrevascularized coronary artery disease will be excluded, so that the isolated prognosis of aortic stenosis can be investigated. All subjects will undergo invasive SAVI measurements during catheterization. Furthermore patients will receive non-invasive testing with an exercise echocardiogram and computed tomography (CT) scan for non-invasive SAVI measurements. The short-term objective will compare SAVI with standard resting indexes for symptom burden, functional capacity, and biomarkers. The long-term objective will associate SAVI and standard resting indexes with clinical outcomes related to valvular disease. The investigators hypothesize that low SAVI (more marked AS during stress) will track with more symptoms and a worse prognosis. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: The patients will have several study visits. The index visit will be planned to obtain informed consent and baseline parameters. The measurement visit(s) will consist of the invasive SAVI measurement, echocardiogram, stress echo imaging, 6-minute walk test, quality of life questionnaire, and the cardiac CT. During the final visit after 12 months, subjects will undergo a CT valvular calcium scan, quality of life questionnaire, and 6-minute walk test. Every subject will have an echocardiogram yearly as suggested by guideline criteria and could possibly be contacted until five years after enrollment. Blood samples will be drawn at baseline and the 1-year follow-up. Potentially the new SAVI metric could identify patients at higher risk among those with moderate gradient AS. However, since no outcome data currently exists regarding SAVI and prognosis, no conclusions could be derived from these measurements until study completion.
Open-label, single-arm, single center pilot study to assess safety and feasibility of administering dexamethasone intrathecally and simvastatin orally during axicabtagene ciloleucel (axi-cel) treatment. Feasibility will be measured by the proportion of patients completing two-thirds (2/3) of their assigned treatments. The study will be deemed feasible if 2/3 or more of the patients complete 2/3 or more of their allocated treatments.
This study investigates a new diagnostic test in detecting SARS-CoV-2, the virus that causes the disease COVID-19. This may help to improve testing for COVID-19.
The purpose of this study is to evaluate the efficacy and safety of atezolizumab in combination with tiragolumab compared with durvalumab in participants with locally advanced, unresectable Stage III non-small cell lung cancer (NSCLC) who have received at least two cycles of concurrent platinum-based chemoradiotherapy (CRT) and have not had radiographic disease progression.
