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.
Background: - Some people with gastrointestinal or ovarian cancer also have ascites. That is free fluid built up in the abdomen. Researchers want to see if a new drug can affect some of the immune cells in the ascites. This may also treat the cancer. Objective: - To look at the immune markers the ascites of people with gastrointestinal or ovarian cancer. Eligibility: - Adults age 18 and older with a malignancy of the GI tract or metastatic ovarian cancer. As a result, they have ascites in the abdomen. Design: - Participants will be screened with: - Medical history, physical exam, and blood tests. - Echocardiogram: sound waves make images of the heart. - Electrocardiogram: measures electrical activity of the heart. - Paracentesis: a needle will be inserted in the abdomen and will remove some of the ascites fluid. - They may have a tumor biopsy. - Participants will get AZD9150 through a vein for 3 hours. They will get this 6 times in cycle 1 and 4 times all other cycles. Each cycle is 28 days. - Each cycle, participants will: - Have a physical exam. - Have blood tests weekly. - Be asked about how they feel and any medicines they are taking. - After every 2 cycles (about every 2 months), participants will have scans and x-rays of their tumor. - Participants will have paracentesis 2 more times during the study. They will have another echocardiogram. - At the end of therapy, participants will have a physical exam and blood tests. They will be asked about how they feel and any medicines they are taking.
Pain associated with sickle cell disease is a common emergency department visit. It is also frequently associated with a high emergency department recidivism rate for pain control and admissions to the hospital. Opiates are considered the first line therapy for acute flares and to manage chronic pain. This often times leads to a stigma of being "opiate seekers" or "frequent fliers". With this study, we wish to explore whether adding ketamine to standard acute opiate therapy (morphine or dilaudid) will decrease subsequent repeat doses of opiates while improving the patient's perception of pain. In addition, we will be exploring whether ketamine as an adjuvant therapy can help reduce hospital admissions for the management of acute sickle cell crisis pain.
Fevers raise the concern for serious bacterial infections in pediatric oncology patients receiving chemotherapy. The gold standard for diagnosing bacteremia (bacterial infection of the blood) is a blood culture. However, bacterial growth may not occur for 48 hours or there can be a false negative result. Thus, the biomarker, procalcitonin, has been investigated for its predictive ability to identify bacteremia earlier than blood culture. We believe that procalcitonin can assist in differentiating bacteremia from non-bacteremia infections in febrile pediatric oncology patients. A reliable predictor of bacteremia infections in pediatric oncology patients should decrease hospitalizations for fever and unnecessary antibiotic treatment. In our study we will measure procalcitonin levels in pediatric oncology patients presenting with fever. We will measure procalcitonin at the time of admission which is part of our standard of care for febrile pediatric oncology admissions. For the purpose of our study, we will additionally measure procalcitonin levels at 12 hours and at 24 hours post admission. We will examine procalcitonin levels at these three timepoints to determine if elevated procalcitonin levels predict bacteremia in pediatric oncology patients with and without neutropenia.
This is a Phase III, multicenter, randomized, double-blind, parallel-arm, active comparator trial to evaluate BI 695500 versus rituximab as a first-line immunotherapy treatment in patients with LTBFL. Patients will be randomly assigned in a 1:1 ratio to receive 375 mg/m2 of BI 695500 or rituximab via intravenous (IV) infusion once a week for 4 weeks (total of 4 dosages administered on Days 1, 8, 15, and 22). Disease assessments will be performed at the End of Study (EOS) Visit at Week 30.

Diabetes increases the risk of cognitive dysfunction. The incidence of dementia is 1.5 to 2.5 times higher in persons with diabetes than the general population. There is evidence that cognitive decline significantly impacts the ability to self-manage diabetes. Strategies to prevent cognitive decline in persons with diabetes has not been well studied. A recent study reported that in persons who had vitamin D deficiency, the risk for all-cause dementia and Alzheimer's was doubled. Vitamin D receptors are located in the brain and deficiency of vitamin D has been reported to negatively affect the development of brain. Therefore, providing vitamin D supplementation to improve cognitive function is worthy of study. The investigators propose a small, randomized controlled trial to determine the effects of vitamin D3 supplementation in persons with type 2 diabetes who have symptoms of cognitive impairment. Persons will be randomized to receive either weekly vitamin D3 supplementation (50,000 IUs) or a matching comparator (5000 IUs) for a period of three months. The study aims are to determine (1) the effect of vitamin D3 supplementation on cognitive function and (2) the effect of vitamin D3 supplementation on diabetes self-management. A sample of persons with type 2 diabetes (n=62), who have a subjective complaint of a cognitive dysfunction or scoring at least one standard deviation below normal on a cognitive functioning screening test, have vitamin D levels less 30 ng/ml, are not depressed (as this impacts cognitive function), and do not have severe diabetes complication will be recruited. Participants will be phone screened and complete two baseline visits prior to randomization. They will then have phone call and follow-up visits to assess (1) cognitive function using standardized tests to assess for executive function (2) serum measurements (HBA1c, fasting glucose, vitamin D levels, and cardiometabolic profile) and (3) surveys to assess cognitive function as well as self-management behaviors.
The purpose of this study is to evaluate the effect of Losartan on cigarette smoke-induced lung injury in smokers and ex-smokers with and without chronic obstructive pulmonary disease (COPD).
This phase 2 trial studies ibrutinib to see how well it works in treating patients with systemic (affecting the entire body) mastocytosis that has spread to other parts of the body and usually cannot be cured or controlled with treatment (advanced). Systemic mastocytosis is a disease in which too many mast cells (a type of immune system cell) are found throughout the body. Mast cells give off chemicals such as histamine that can cause flushing (a hot, red face), itching, abdominal cramps, muscle pain, nausea, vomiting, diarrhea, low blood pressure, and shock. Ibrutinib may stop the growth of mast cells by blocking some of the enzymes needed for cell growth.
The purpose of this study is to find at least one dose of BMS-955176 that will be safe, effective and tolerable for HIV-1 infected treatment naive adults.
The aim of this project is to evaluate the efficacy of the influenza vaccine in individuals with major depressive disorder (MDD) as well as to elucidate the nature of the immunological abnormalities in MDD using a quasi-experimental design. Specifically, the investigators plan to induce transient, mild inflammation in medically-healthy study participants using the influenza vaccine. Initially the investigators will conduct a pilot project with up to 20 individuals in order to evaluate the time-point at which the peak inflammatory response to the vaccine occurs. Subjects will receive the seasonal influenza vaccine and provide blood samples 4 hours, 2 days, and 30 days post vaccination. Subsequent to the pilot study, both depressed and psychiatrically-healthy participants will be randomized in a parallel group, double-blind design so that they receive either influenza vaccine (seasonal vaccine) or saline (i.m). At baseline, subjects will provide a blood sample, complete a number of rating scales to measure mood and fatigue, and may complete approximately one hour of MRI scanning with or without simultaneous EEG recording. Two-days post vaccination, they will provide a second blood sample, complete more clinical ratings and may complete another identical MRI session with or without simultaneous EEG. Four weeks later, participants will be asked to return to provide a third blood sample and complete additional clinical ratings. The blood samples will be used to measure both innate and adaptive immune function and may be used to correlate the vaccine-induced immunological changes to neurophysiological changes in the brain measured by MRI and/or EEG.
