The purpose of the study is to evaluate if rifaximin alone or rifaximin plus lactulose delays the onset of hepatic encephalopathy (HE) in participants with cirrhosis who have had a previous episode of HE.
NCT02239120
This trial will enroll approximately 6,000 patients with recent embolic stroke of unknown source (ESUS). Patients will be randomized to dabigatran or acetylsalicyclic acid (ASA) (1:1 ratio) and have visits every three months. The study doctor may prescribe blinded concomitant ASA for pts with coronary artery disease but this is not mandatory. All Adverse Events (AEs), Serious Adverse Events (SAEs), outcome events will be recorded. The trial will conclude when the required number of stroke events are positively adjudicated which is estimated to take 3 years (including 2.5 years of enrollment).
NCT01287585
This is a study of ADI-PEG 20 (pegylated arginine deiminase), an arginine degrading enzyme versus placebo in patients with hepatocellular carcinoma who have failed prior systemic treatment (chemotherapy). Hepatocellular carcinomas have been found to require arginine, an amino acid. Thus the hypothesis is that by restricting arginine with ADI-PEG 20, the hepatocellular carcinoma cells will starve and die.
NCT03360071
This is a randomized, parallel-group, double-blind, phase 2, single center, proof-of-concept study which will evaluate the effect of a preparation of FDA approved allergens (PMA) used as a sub-cutaneously administered immunotherapy for the management of allergic rhinitis (perennial and seasonal).

NCT03092687
Background: The Human Brain Collection Core (HBCC) collects brain and other tissues. They get these from deceased people who may or may not have had psychiatric disorders. The next of kin gives permission for researchers to get the tissues. Researchers want to collect medical details of people whose brains are donated. They also want to use the donated tissue to study brain chemistry and structure. This could lead to better treatments for mental illness. Objective: To create a collection of human brain tissue to learn about the causes and mechanisms of mental disorders. Eligibility: People willing to donate their deceased relative s brain tissue. The deceased person could not have had any of the following: Severe mental retardation Long-lasting seizure disorder Infections that affect the brain Decomposition Brain damage Being on a respirator for more than 12 hours Major sepsis Serious renal or hepatic disease Certain dementias and degenerative diseases Design: Medical Examiner s Offices will screen donors who have recently died. Some others will be screened by hospitals or funeral homes. Participants will be the next of kin. They will give consent for HBCC to obtain brain tissue from the deceased person. The tissue will be frozen for future research. Participants will have a 30-minute phone call. They will answer questions about the deceased person s medical and psychiatric conditions. They will answer questions about the person s use of medicines and drugs. Participants will be contacted by a social worker. They will be asked for permission to access the deceased person s medical records.
NCT02141490
Background: People with prostate, bladder, or kidney cancer often have their cancer spread (metastasize) to lymph nodes. It is important for your doctor to know if this has occurred but currently it can be hard to determine if this has occurred on standard imaging studies like computed tomography (CT) or magnetic resonance imaging (MRI). This study uses an agent called Ferumoxytol to identify lymph nodes that might be involved by cancer. Objective: \- To see how well Ferumoxytol can detect lymph node metastases in patients with prostate, bladder, or kidney cancer. Eligibility: -Adults over age 18 with prostate, bladder, or kidney cancer with lymph node involvement. Design: * Participants will be screened with a medical history. * Participants will have blood drawn and a physical exam. Their vital signs will be measured. They will answer questions about their health and current medications. * Participants should not have a history of iron overload or have an allergy to Ferumoxytol. * Participants will have a magnetic resonance imaging (MRI) scan. The scanner is a metal cylinder with a strong magnetic field. Participants will lie on a table that slides in and out of the scanner. They will have a standard sensor, known as a coil, wrapped around their abdomen to improve the scan. This is like a small blanket with wiring inside. Participants will need to lie still on the scanning table for about 1 hour. * Participants will have an ultrasound. This uses harmless sound waves to provide pictures of organs or tissues inside the body. * Participants will receive an injection of Ferumoxytol through an intravenous line. A very thin plastic tube will be inserted into a vein in order to inject the agent. * Participants will have another MRI and ultrasound 24 and 48 hours after injection. * The study will follow participants medical course for at least 1 year.
NCT02182986
Solid organ transplantation is an important therapeutic option for children with a variety of end stage diseases. However, the same immunosuppressive medications that are required to prevent the child's immune system from attacking and rejecting the transplanted organ can predispose these individuals to developing a very serious cancer that is linked to Epstein-Barr virus (EBV).
NCT03638635
The transversus abdominis plane (TAP) block can be used to reduce pain in patients who get abdominal surgery. TAP blocks are given with a local anesthetic. The purpose of this study is to compare pain medication usage after surgery between two different types of local anesthetic: liposomal bupivacaine and standard bupivacaine.
NCT03988114
The reason for this study is to see if the drug abemaciclib in combination with nonsteroidal aromatase inhibitors (anastrozole or letrozole) is effective in participants with Hormone Receptor Positive (HR+), Human Epidermal Growth Factor Receptor 2 Negative (HER2-) advanced breast cancer that have certain disease characteristics.
NCT02421887
The objective of the Males, Antioxidants, and Infertility (MOXI) Trial is to examine whether treatment of infertile males with an antioxidant formulation improves male fertility. The central hypothesis is that treatment of infertile males with antioxidants will improve sperm structure and function, resulting in higher fertilization rates and improved embryo development, leading to higher pregnancy and live birth rates. Findings from this research will be significant in that they will likely lead to an effective, non-hormonal treatment modality for male infertility. An effective treatment for men would also reduce the treatment burden on the female partner, lower costs, and provide effective alternatives to couples with religious or ethical contraindications to ART (Assisted Reproductive Technology). If antioxidants do not improve pregnancy rates, but do improve sperm motility and DNA integrity, they could allow for couples with male factor infertility to use less intensive therapies such as intrauterine insemination. Male fertility specialists currently prescribe antioxidants based on the limited data supporting their use. A negative finding, lack of any benefit, would also alter current treatment of infertile males.
NCT00369707
Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the cancer. Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Giving bortezomib together with rituximab may kill more cancer cells. This phase II trial is studying how well giving bortezomib together with rituximab works as first-line therapy in treating patients with low-grade B-cell non-Hodgkin's lymphoma.
NCT02082522
Photodynamic therapy (PDT) is a combination of a drug, porfimer sodium (Photofrin), which is activated by a light from a laser that emits no heat. This technique works to allow the medical doctor to specifically target and destroy abnormal or cancer cells while limiting damage to surrounding healthy tissue. The activation of the drug is done by lighting the abnormal areas using a fiber optic device (very fine fiber like a fishing line that permits light transmission) inserted into a flexible tube with a light called cholangioscope for the bile duct. The light will activate the porfimer sodium concentrated in the abnormal tissue, leading to its destruction. This research study will evaluate the efficacy and safety of PDT with porfimer sodium administered with Standard Medical Care (SMC) compared to SMC alone on the overall survival time of patients with non-operable advanced cholangiocarcinoma, a rare cancer of the bile ducts. It will involve 200 patients across North America and Europe. Other countries may participate if needed. Participation will last at least 18 months.

NCT02262052
The Theia-study is a prospective, multicenter, single-arm management (cohort) study. Consecutive patients with clinically suspected acute, recurrent, ipsilateral, proximal deep vein thrombosis (DVT) of the leg, who fulfil all the inclusion criteria and meet none of the exclusion criteria, are eligible for inclusion and will be managed according to the result of a magnetic resonance direct thrombus imaging (MRDTI) of the affected leg. The MRDTI is to be performed and adjudicated within 24 hours of study inclusion. The final treatment decision will be made based on this ruling of the MRDTI. In case of a positive MRDTI signal, patients will be treated with therapeutically dosed anticoagulants or modified in patients with a recurrent DVT on anticoagulant therapy. Patients with a negative MRDTI ruling will be left untreated, or treatment will be remained unadjusted if they are on anticoagulant treatment at inclusion. All patients with negative MRDTI will be subjected to a standardized compression ultrasonography (CUS) within 48 hours after initial presentation. The latter CUS serves as a reference test in case the patient returns with symptoms of ipsilateral recurrence in the future, and will not be used for management decisions at baseline. The study flowchart can be found in Appendix A. All patients will be followed for three months for the occurrence of acute recurrent venous thrombo-embolism (VTE). In case of suspected recurrent VTE, objective testing including either computed tomography pulmonary angiography (CTPA) for PE or CUS for DVT will be performed. Additionally, in case of a proven ipsilateral recurrent DVT during follow-up, MRDTI will be repeated.
