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.
Myelofibrosis (MF) is a bone marrow illness that affects blood-forming tissues in the body. MF disturbs the body's normal production of blood cells, causing extensive scarring in the bone marrow. This leads to severe anemia, weakness, fatigue, and an enlarged spleen. The purpose of this study is to see how safe and tolerable ABBV-744 is, when given alone, and in combination with ruxolitinib or navitoclax, for adult participants with MF. ABBV-744 is an investigational drug being developed for the treatment of MF. The study has 4 segments - A, B, C, and D. In Segment A, the safe dosing regimen of ABBV-744 is identified and then, given alone as monotherapy. In Segment B, C, and D, combination therapies of ABBV-744 with either ruxolitinib or navitoclax are given. Adult participants with a diagnosis of MF will be enrolled. Around 130 participants will be enrolled in 60 sites worldwide. In Segment A, participants will receive different doses and schedules of oral ABBV-744 tablet to identify safe dosing regimen. Additional participants will be enrolled at the identified monotherapy dosign regimen. In Segment B, participants will receive oral ruxolitinib and ABBV-744 will be given as "add-on" therapy. In Segment C, participants will receive ABBV-744 and oral navitoclax. In Segment D, participants will receive ABBV-744 and ruxolitinib. Participants will receive treatment until disease progression or the participants are not able to tolerate the study drugs. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of treatment will be checked by medical assessments, blood and bone marrow tests, checking for side effects, and completing questionnaires.
The researchers are doing this study to find out whether the researchers can combine information provided by PET/MRI scans with information from tests on blood and tissue samples to develop a very detailed description (profile) of high-grade serous ovarian carcinoma (HGSOC), which could improve our ability to treat this disease. The study researchers will use computers to analyze the combined results of the imaging tests and the genetic and immune system tests on the tumor samples. The study researchers think that this information will help them more accurately predict the way tumors respond to treatment, which may improve their ability to individualize treatments for this disease.
To evaluate the feasibility of a fully randomized validation trial for the Oxalert EPO.
Phase I/II, open label, multicenter, multinational (Japan, Brazil and the US) extension study of JR-171-101 for the treatment of MPS I
The goal is to provide health care professionals, including dentists, with the best possible evidence for clinical decision making when deciding upon analgesics for acute post-surgical pain management, a double-blind, stratified randomized clinical trial will be conducted to test the hypothesis that a combination of over-the-counter non-opioid containing analgesics is at least as, if not more, effective (non-inferior) than the most commonly prescribed opioid analgesic. The impacted 3rd molar extraction model will be used due to the predictable severity of the post-operative pain and generalizability of results. This double-blind, prospective, stratified, randomized pragmatic clinical trial will use the impacted 3rd molar extraction pain model.
With the introduction of effective anti-retroviral therapy (ART), HIV-infected persons can now survive for decades, but this success has been accompanied by an increased risk of developing metabolic disease and diabetes in HIV-infected persons compared to the general population. Recent studies from HIV-negative subjects have identified several associations between circulating immune cell populations and impaired glucose tolerance, including increased activated CD4+ and CD8+ T cells, and reduced regulatory T cells. Of note, these same changes in peripheral T cell subsets are frequently observed in patients with chronic HIV infection. The goal of this study is to assess whether the circulating T cell distribution is reflective of the adipose tissue T cell distribution, and to understand whether chronic adipose tissue T cell activation may impair adipocyte (i.e., fat cell) function and insulin sensitivity. If the investigators' hypotheses are correct, this will demonstrate that chronic peripheral immune activation (i.e., high memory T cells, low naïve cells, and increased expression of activation surface markers) is associated with greater adipose-resident CD4+ and CD8+ T cell expression of activation markers, adipose tissue inflammation, and insulin resistance.
The main purpose of this study is to evaluate the safety and tolerability of LY3372993 in participants with AD, non-Japanese, and Japanese healthy participants who are of first-generation Japanese origin. The study will also investigate how much LY3372993 gets into the bloodstream and will test the effects of LY3372993. The study will be conducted in two parts. The part A includes participants with AD and part B includes healthy participants. Participation could last up to about 61 weeks and may include up to 31 visits to the study center.
Single-center study to determine the relationship between changes in depression symptoms and electroencephalographic (EEG) patterns induced by electroconvulsive therapy (ECT)
TRACK-MSA is an observational, non-interventional, longitudinal natural history study to define changes in clinical, neurological, blood, CSF, and neuroimaging biomarkers in patients with multiple system atrophy (MSA) comparing baseline to 6-month and 1-year assessments. The study will enroll 50 patients with MSA-P or MSA-C at 2 or more participating sites.
In a retrospective community based cohort study from Pueblo County Colorado which has a higher population proportion of metabolic syndrome and diabetes mellitus, we hope to clarify and quantify an association of the AGE HBa1c elevation with the early subclinical hemodynamic changes of diabetic cardiomyopathy as measured by LAV, LVM, E/A ratio, E/e' ratio and BNP in patients with stage A heart failure.
