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 observational study will obtain liver biopsy samples and evaluate the long-term effect of adeno-associated virus (AAV)-mediated gene therapy on the liver tissue in adult patients with hemophilia A or hemophilia B who have previously been treated with a factor VIII or factor IX gene-containing AAV-vector for liver-targeted gene transfer. Participants are from a cohort of patients treated with AAV-mediated gene transfer and at least 6 months after vector infusion
This is a phase IV, unblinded, open-label study assessing the impact on skin quality, hydration, and barrier of three (3) Hydrafacial treatments in healthy adults of Fitzpatrick Skin Types I & II, III, IV, V & VI, 30 to 55 years of age. Efficacy and subject satisfaction will be assessed, before and after three (3) HF treatments, in 6 patient cohorts, each cohort defined by FST I-VI.
Objectives: The investigators will test whether combination of chemoimmunotherapy or dual agent immunotherapy alone improves efficacy for patients with MPM. Primary Objectives: The primary objective is to test whether the combination of platinum-based chemotherapy and pemetrexed with durvalumab / tremelimumab or durvalumab / tremelimumab alone improves recurrence-free survival for patients with resectable MPM compared to historical, published data for surgery with chemotherapy. Secondary Objective(s): The secondary objectives are to determine the safety of and whether the platinum-based chemotherapy and pemetrexed with durvalumab / tremelimumab or durvalumab / tremelimumab alone improves response rate, resectability, major pathological response, and complete pathological response. Exploratory Objective(s): The exploratory objectives are to determine the safety of and whether the platinum-based chemotherapy and pemetrexed with durvalumab / tremelimumab or durvalumab / tremelimumab alone improves response rate, resectability, major pathological response, and complete pathological response for patients with epithelioid and non-epithelioid histologies. The scientific exploratory objectives include: 1. Develop an NGS plasma assay of common mutations identified from our previous grant cycle to prospectively measure minimal residual disease (MRD) after resection as a potential, novel biomarker test in mesothelioma. 2. Determine the predictive role of BH3 profiling in patients undergoing neoadjuvant ICI followed by surgery: With patient samples collected from our neoadjuvant ICI trial, the investigators will test whether BH3 profiling from pre-treatment tumor biopsies and PBMC predicts clinical, radiological, and pathological responses to ICIs. The investigators will identify TAMs from the TiME in MPM tumor samples before and after treatment to compare differences in polarization induced by ICI in clinical and pathologically responding versus non-responding patients.
Research suggests that Whole Body Hyperthermia in a sauna-like environment can reduce symptoms related to post-acute sequelae of SARS-CoV-2 (PASC), or Long Covid. The investigators aim to study the feasibility and treatment effect of this procedure for patients experiencing Long Covid symptoms.
The suicide rate among active duty service members and Veterans increased substantially following the onset of post-9/11 conflicts in Iraq and Afghanistan. Accordingly, Veteran suicide prevention has been identified as a national healthcare and research priority. The investigators will recruit 136 female and male Veterans who have been hospitalized for suicide risk and randomly assign them to receive one of two psychotherapy treatments for suicide risk after they leave the hospital. The goals of this study are to examine if a) a longer psychotherapy causes greater improvements in coping skills and reductions in negative suicidal thinking, b) a longer psychotherapy is more effective in reducing suicide risk, and c) if Veterans with a history of multiple suicide attempts are more likely to benefit from the longer psychotherapy. Additionally, this study will use magnetic resonance imaging (MRI) neuroimaging scans of Veterans shortly after they leave the hospital and again 4- and 12-months later. This study will explore a) if brain markers can predict suicide attempts, b) if brain markers change over time as suicide risk changes, and c) if brain markers change differently for the two types of psychotherapy.
Regular exercise participation is known to reduce cardiometabolic disease risk but the impact that exercise training has on adipose tissue (AT) metabolism is poorly understood, particularly in humans. It is well established that exercise training improves whole-body glucose levels and increases insulin sensitivity, and this can occur within one or two weeks. These effects are usually due to adaptations in skeletal muscle, the tissue responsible for the majority of glucose disposal. However, many studies have now determined that exercise training also results in adaptations in AT that improve whole-body metabolic health by improving glucose uptake into the AT. Skeletal muscle is thought to account for approximately 75-85% of glucose uptake , and this process is impaired in .individuals who are insulin-resistant state. It is postulated that the increased level of adiposity that accompanies severe obesity would result in higher dependency on AT for glucose uptake as the AT would be a bigger "sink". Thus the role of AT in inducing whole body insulin resistance is still unclear, particularly in individuals with obesity. This study will examine the changes in AT glucose uptake before and after 4 weeks of exercise training in obese individuals and establish if there are sex differences.
This clinical trial evaluates a remotely delivered, culturally tailored weight loss interventions in Latina breast cancer (BC) survivors. Cancer is the leading cause of death among Latinos, and among Latinas, BC is the leading cause of cancer death. An estimated 80% of Latinas in the United States have overweight/obesity, which is associated with poorer BC outcomes. However, few, if any, effective interventions exist to promote and maintain weight loss in Latina BC survivors. The development of an adaptive program that provides survivors the support they need, as opposed to what is typically available, is essential to reducing persistent inequities in cancer survivorship.
Investigators' recent findings from the pilot clinical trial in MCI individuals demonstrated EVOO improved vascular function and memory. Yet, up to date, whether EVOO protects against AD in individuals with a family history of AD is unknown. Thus, in this study, the investigators will recruit healthy individuals with a family history of AD for participation. From eligible participants, blood samples for ApoE genotyping will be collected, followed by metabolomics, lipidomics, and transcriptomics analyses at baseline. Participants will be randomized into 2 groups (n=20 each); one group will receive EVOO daily (~2 tablespoons, 30 ml) for 6 months, and the second group will not receive olive oil. Both group participants will receive educational information on brain health and how environmental factors such as lifestyle, diet, and exercise could impact brain health. After 6 months, another blood sample will be collected from the participants to evaluate the effect of EVOO on metabolites, lipids, and genes, and thus physiological pathways. The investigators will perform non-targeted and comprehensive metabolomics, lipidomics, and transcriptomics analyses. Examples of metabolites to be analyzed are antioxidative and anti-inflammatory metabolites, neurotransmission, mitochondrial, tryptophan, and purine metabolisms. Examples of lipidomics include sphingomyelins (SMs), cholesterol esters (ChEs), phosphatidylcholines (PCs), phosphatidylethanolamines (PIs), phosphatidylinositols (PIs), and triglycerides (TGs). Transcriptomics will be used to identify changes in mRNAs involved in different pathways contributing to AD, such as genes involved in inflammation and oxidative stress, in both ApoE-dependent and independent fashion.
This is a trial with an observational and an interventional arm, in patients with moderate to severe anemia and control subjects. The main purposes of this study is to phenotype the scope of neurocognitive deficits from iron deficiency anemia (IDA) in adult women, determine derangements in cerebral perfusion, vascular reactivity, functional connectivity, and blood brain barrier permeability in adult-onset IDA and relate them to neurocognitive deficits, as well as determine the reversibility and durability of both the physiologic and neurocognitive derangements by iron replacement therapy. All eligible subjects will be asked to provide informed consent before participating in the study.
Clinical research participation has historically been heavily biased toward specific demographics. This study will invite several participants to gather a wide range of information on clinical trial experiences for squamous cell carcinoma patients. The aim of the study is to identify the factors that limit the ability of a person to enroll in, as well as complete a clinical trial for treatment of squamous cell carcinoma. People with squamous cell carcinoma who are invited to take part in clinical research will benefit from the analysis of the data.
