NCT02251366
Intravitreal delivery of anti-vascular endothelial growth factor (VEGF) drugs has revolutionized the management of neovascular age-related macular degeneration (NVAMD). However, the requirement for near monthly administration of therapy coupled with the growing number of patients needing treatment has become a universal challenge in efficient delivery of care for retina physicians. While many retina practices have both increased the size of their staffs to accommodate the growing patient population and increased efficiency with the aid of digital photography, patient encounter times in clinic continue to increase, often spanning 2-4 hours. While maintaining the highest level of patient care, a streamlined alternative in the evaluation of patients with NVAMD to determine whether intravitreal therapy with an anti-VEGF agent is indicated at a particular office visit would be desirable. This multi-satellite, prospective, randomized pilot study will compare standard-of-care, physician- based retinal evaluation, defined as retinal examination by a physician and standard imaging with optical coherence tomography (OCT) and optional fluorescein angiography (FA), versus physician-guided diagnostic evaluation, defined as standard imaging with OCT and optional FA without retinal examination by a physician in the management of NVAMD with anti-VEGF therapy. Outcomes for this study are aimed primarily at demonstrating that the physician-guided diagnostic approach to managing patients with NVAMD is not inferior to the physician-based retinal evaluation based on measures such as a change from baseline in visual acuity and in central subfield thickness (CSF) on OCT. Other outcomes to be assessed in this study are length of visit times, numbers of intravitreal injections of anti-VEGF agents administered, numbers of diagnostic tests performed to determine whether treatment should be given at each visit, and frequency of retinal examinations performed for each participating patient in each cohort. Perceptions of quality of vision and patient satisfaction will be captured by interviews with patients following each clinic visit; clinical impressions of physicians will be captured by a brief physician survey. Finally, the feasibility of recruiting patients, as measured by how many eligible patients are seen at each Wilmer satellite, how many patients agree to be randomized, how many patients follow-up, and the attrition rates at the 4 and 8-month outcome visits will be assessed.
NCT01281995
Background: \- Corticosteroids have been used to treat inflammation and immune system diseases for decades. However, despite their widespread use, there is little information on the specifics of how corticosteroids affect the immune system in humans. The Center for Human Immunology, Autoimmunity, and Inflammatory Diseases is interested in studying how the steroid hormone hydrocortisone affects the immune system in healthy volunteers, and in doing so to understand how hydrocortisone given at different doses works in treating many immune and inflammatory conditions. Objectives: \- To evaluate the effects of hydrocortisone on the immune and inflammatory responses of healthy volunteers over the short and intermediate term (up to 28 days after administration). Eligibility: \- Healthy volunteers at least 18 years of age. Design: * Participants will be screened with a full medical history and physical examination, and blood and urine tests. At this visit, participants will be separated into two groups, with each group scheduled to receive a different amount of hydrocortisone during the study visit. * One week before the study visit, participants will provide a blood sample for baseline testing. * Participants will be admitted for a 24-hour inpatient stay that will involve frequent blood draws. Between blood draws, participants will be able to work, watch TV, walk around, and so on, and will be provided with regular meals. * Blood will be drawn 1 hour before the infusion of hydrocortisone. Participants will be divided into two further sets of groups with different blood draw schedules: * Groups 1 (lower dose) and 2 (higher dose) will have blood draws 1, 4, 8, 12, and 24 hours after the hydrocortisone infusion. * Groups 3 (lower dose) and 4 (higher dose) will have multiple blood draws over 24 hours, with timing based on data from the previous groups blood test results. * Participants will provide additional blood samples 7 and 28 days after the in-patient visit....
NCT01818440
Background: \- Researchers are interested in comparing two methods that doctors can use to position catheters in blood vessels. These methods are used to deliver chemotherapy and close the blood supply to a tumor. The methods are the standard method called fluoroscopy and a new way called 3-D Roadmap. The 3-D Roadmap software uses computed tomography (CT) images to help the doctor choose the best position for the catheter to get to the tumor. The computer shows the route on an x-ray screen in real time. This technique may help doctors position the catheter with less x-ray dye and in a shorter time. These methods will be compared in people who are having a procedure to destroy liver tumors. The procedure, called trans-arterial embolization, will deliver chemotherapy and destroy the tumor blood supply. Objectives: \- To compare the effectiveness of fluoroscopy or 3-D Roadmap software for liver tumor treatment. Eligibility: \- Individuals at least 18 years of age who are having trans-arterial embolization for liver cancer. Design: * Participants will be screened with a physical exam and medical history. They will provide blood and urine samples, and have imaging studies. * Participants will be divided into two groups. One group will have regular fluoroscopy (X-ray) during the procedure. The other group will have the procedure with the 3-D Roadmap software. * In the first group, participants will have a CT scan. The doctor will decide how many vessels need to be treated. The doctor will advance the catheter using fluoroscopy only. Another CT scan will be given after the procedure. * In the second group, participants will have a CT scan. The doctor will look at the scan with the 3-D Roadmap software. The software will show the path to advance the catheter. The doctor will use the software to help destroy the tumors. Another CT scan will be given after the procedure. * Both groups will have the same follow-up care afterward. Other tests will be given as needed for the cancer treatment.
NCT01547832
Background: \- Early-onset Parkinson's disease (EOPD) is more likely to be caused by gene mutations than Parkinson's disease that develops in older people. Studying these mutations may help find therapies for EOPD. Researchers want to study mutations on a gene called PARK2. These mutations prevent fat uptake into cells and may interfere with normal brain function. Researchers want to study fat and cholesterol in the body to look at the effects of these mutations on the body and brain. Objectives: \- To study connections between genetic mutations and EOPD. Eligibility: * Individuals between 18 and 80 years of age with EOPD. * Individuals between 18 and 80 years of age with no family history of Parkinson s disease. Design: * Participants will be screened with a physical exam and medical history. Blood and urine samples will also be collected. * Participants will have some or all of the following tests: * Blood samples and tissue (skin and fat) biopsies * Cell line development from these tissue samples to study the function of PARK2 * DEXA scan to measure body fat context using low dose x-rays * Glucose and insulin tolerance testing to measure blood sugar levels. * Treatment will not be provided as part of this protocol.

NCT00134017
RATIONALE: Giving chemotherapy before a donor bone marrow transplant helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclophosphamide, mycophenolate mofetil, or tacrolimus after transplant may stop this from happening. PURPOSE: This clinical trial is studying how well giving combination chemotherapy together with tacrolimus and mycophenolate mofetil works in treating patients who are undergoing a donor bone marrow transplant for hematologic cancer.
NCT02367521
Traumatic brain injury (TBI) is frequently complicated by depression and other problems such as post traumatic stress disorder (PTSD), sleep disturbance, cognitive deficits and behavioral problems. Untreated depression can lead to reduced productivity and poor global outcome. There is no Food and Drug Administration (FDA) approved drug for the treatment of TBI-related depression. The overarching goal of this small study is to determine the effectiveness of low frequency right (LFR) rTMS for the treatment of post-TBI depression and co-occurring psychiatric symptoms. Repetitive transcranial magnetic stimulation (rTMS) is a brain stimulation technique. It involves generating a brief magnetic field in a coil that is placed on the scalp. The magnetic field passes through the skull and induces a weak electrical current in the brain that briefly activates neural circuits at the stimulation site. Adults aged 18 and older, with a history of head injury of mild or moderate severity , who are currently experiencing symptoms of clinical depression may join the study.
NCT00278343
This phase II trial is studying how well cediranib maleate works in treating patients with persistent, recurrent, or refractory advanced ovarian epithelial, peritoneal cavity, or fallopian tube cancer. Cediranib maleate may stop the growth of tumor cells by blocking blood flow to the tumor and by blocking some of the enzymes needed for cell growth.
NCT01438554

NCT02186704
The primary aim of the "Sensing Atrial High Rate Episodes with DX System in Implantable Cardioverter Defibrillators Trial" (SENSE Trial) is to assess the efficacy of a implantable cardioverter-defibrillator (ICD) lead with dedicated atrial sensing dipoles in detecting atrial high rate episodes. The study hypothesis is that an ICD system with a lead with dedicated atrial sensing dipoles will have a diagnostic yield comparable to that of a standard dual chamber ICD system and superior to that of a standard single chamber ICD system.
NCT02794519
Sirukumab is a fully human anti interleukin (IL)-6 immunoglobulin G1-kappa monoclonal antibody (MAb) which is in development for the treatment of rheumatoid arthritis (RA). The continuing unmet need in subjects with asthma refractory to corticosteroid therapy and increased understanding of asthma pathogenesis have stimulated the development of targeted biologics based on predictive biomarkers. The majority of approaches to date have targeted T Helper 2 (Th2) cytokines or their downstream effects. Targeting IL-6 in severe asthma represents an unprecedented approach that has potential to address non-Th2 drivers of severe asthma. This multicenter, randomized, double-blind (sponsor-unblind), placebo-controlled, parallel group study will investigate the efficacy of sirukumab compared to placebo in subjects having uncontrolled severe asthma despite use of high dose inhaled corticosteroid (ICS) in combination with long-acting Beta-agonist (LABA). The study will employ a variable treatment period for individual subjects. Dosing will continue every 4 weeks until week 44 (inclusive), or until 24 weeks after the final subject has been randomized, whichever the sooner. Upon receiving the final dose of study medicine or placebo, subjects will enter a 16 week Follow Up period. Overall, the duration of participation for subjects who complete the full 44-week treatment period and Follow Up period may be up to 64 weeks. Approximately 175 subjects will be randomized such that 140 evaluable subjects complete the study.
NCT02886702

NCT03318575
The purpose of the study is to evaluate the hypothesis that patients receiving remote ischemic conditioning using the autoRIC device show statistically significant reduction in the prevalence of ischemia-reperfusion injury to the myocardium as compared to patients in the autoRIC Sham device arm (within 12-24 hours post non-emergent PCI with stent implantation).
NCT00032344
Colorectal cancer is a leading cause of cancer death in the United States. Mortality remains high because most colorectal cancers are detected after there has been regional or distant spread, precluding curative surgical resection. With this in mind, screening strategies have been recommended for asymptomatic individuals which hope to reduce mortality from colon cancer by detecting and removing premalignant adenomatous polyps or early malignant lesions. Screening of asymptomatic individuals over age 50 with sigmoidoscopy and fecal occult blood tests has been advocated by the American Cancer Society. However, current screening will identify only 50% of patients who have adenomatous polyps. More sensitive tests for polyp detection, like colonoscopy, are costly, require extensive resources and are unlikely to be used for screening large populations. Ideal screening would identify patients with the highest risk of cancer and target more sensitive screening tests at this population. The identification of low cost, easily collectible risk factors which can be used to target patients for the more sensitive screening tests is the primary purpose of this study. Since a major segment of the veteran population is over the age of 50, there will be a substantial impact in reduction of both mortality and morbidity due to colon cancer and attendant cost savings to the VA for treatment if such risk factors can be identified. Phase I is a cross-sectional study designed to identify risk factors for large (\>1 cm) adenomatous polyps. Approximately 3200 asymptomatic subjects (age 50-75) have completed risk factor assessment, medical and dietary histories, and have undergone complete colonoscopy examination. This will identify for comparison purposes a polyp-free control group and is the first large prospective study to include such a group. Data at colonoscopy will characterize the prevalence, size and distribution of adenomatous polyps. This will permit an assessment of sensitivity of sigmoidoscopy in this population. In addition, tissue from normal rectal mucosa will be analyzed for evidence of cell proliferation activity. The primary focus of Phase I is a risk factor analysis. A multivariate analysis will be performed to determine the relationship of historical and environmental factors as well as cell proliferation activity with the presence of adenomatous polyps. A cohort consisting of a subgroup of polyp patients (large and small) and matched polyp-free controls will be tracked longitudinally to determine polyp occurrence/recurrence rates. Phase II of the study is a long-term follow-up study designed to evaluate the relative risk of two repeat colonoscopies. Phase III is an extension in follow-up of an additional five years, a total of ten years in all, to include all study patients. The primary focus will be on documenting long-term mortality and medical outcomes as well as occurrence/reoccurrence of neoplasia with special emphasis on ten-year cancer rates.
