This will be an open-label, parallel-group study to evaluate the pharmacokinetics of GSK1278863 and metabolites in normal subjects and subjects with impaired renal function, including those who are hemodialysis dependent. GSK1278863 will be administered once daily for 14 days to normal subjects and subjects with Stage 3 and Stage 4 renal function, and 15 days to subjects with Stage 5 renal function. Pharmacokinetic assessments will be made on Days 1 and 14 (normal subjects, subjects with Stage 3 and Stage 4 renal function) or Days 14 and 15 (dialysis and non-dialysis days; Stage 5).
Valortim is the name of the experimental drug that volunteers will receive in this study. Valortim may also be called MDX-1303. Experimental means that the drug is not yet approved by the Food and Drug Administration (FDA). Valortim is a monoclonal antibody (laboratory-made immune system molecule) for the treatment of inhalation anthrax (when the infection starts in the lungs). Valortim works by attaching itself to part of the anthrax toxin preventing the toxin from doing damage to cells. This study is being conducted to see if Valortim given over 120 minutes is safe and tolerable. This study will take place in five parts: Screening Phase, Check-in Phase (the day you arrive at Quintiles to start the study), Treatment Phase (the time when you receive the study medication), Follow-up Phase (the time after you receive the study medication) and Final Visit.
This is an observational, physiology pilot study of subjects with overactive bladder, insomnia and normal subjects. No study drug will be given. All subjects will complete a one week sleep diary and a 3-day bladder diary. After one week, subjects meeting eligibility requirements will complete a single sleep night stay in a sleep laboratory setting. During the sleep night stay, subjects will be evaluated using cystometry and polysomnography. In the morning following the sleep night stay, subjects will complete a sleep questionnaire and this will complete their participation in the study.
Hypothesis: Low dose aspirin does not change exhaled inflammatory breath mediators in normal subjects.
Type 1 diabetes mellitus (T1DM) is an autoimmune disease. Autoimmune diseases happen when the immune system does not identify part of the body as belonging to it. The immune system then destroys that part as if it were an unknown tissue in the body. In T1DM, the body kills the cells in the pancreas that produce insulin. Insulin is the hormone that "unlocks" the cells of the body. It allows glucose to enter and fuel them. Special cells in the body called islets make the insulin. Since glucose cannot enter the cells, it builds up in the blood. The body's cells literally starve to death. Children are at risk of developing T1DM and the risk is much higher than other severe, chronic childhood diseases. The only treatments are a careful diet, planned physical activity, and testing blood sugar levels several times a day. The patient must also inject insulin each day or use an insulin pump. There is no cure for T1DM. Insulin injections are considered life support, because going without insulin for just a few days causes the blood to have too much acid in it and that can lead to death. On the other hand, taking too much insulin makes blood sugar levels go too low, and if untreated, can lead to death as well. DiaKine is developing Lisofylline to treat the failed immune system. This is what caused T1DM in the first place and it does not go away. The purpose of this study is to see how safe the study drug is. The study is also going to compare the levels of study drug in the blood and to measure the effect of the study drug on other substances in the blood that are linked to type 1 diabetes. These levels will be measured after the study drug is given as an injection under the skin and an injection into the vein. To date, Lisofylline has been tested when given as an injection in the vein. The investigators hypothesize that Lisofylline will be safe when given as an injection under the skin and in the vein and that levels of study drug will be very similar when given as an injection under the skin and in the vein. The investigators also hypothesize that Lisofylline will have a positive effect on the substances in the blood that are linked to type 1 diabetes.
The purpose of this study is to demonstrate the feasibility of near-infrared fluorescence imaging in subjects with acquired or hereditary lymphedema, in subjects with lipidema and other lymphovascular disorders and in normal health subjects; in order to attempt to correlate imaging phenotype(s) with genotype(s).
The study will investigate whether GSK1362885 is safe and well-tolerated when administered to normal healthy subjects. The study will also measure blood levels of the study drug to determine how the body processes the drug (pharmacokinetics) and what effects the drug has on the body (pharmacodynamics).
The objective of this study is to assess and compare the pharmacokinetic properties of YM178 in normal subjects and those with mild, moderate and severe renal impairment.
This study examines the effects of an antidepressant medication and placebo on the brain functioning of normal subjects. In this study, recordings of brain electrical activity are being used to detect and monitor the response to treatment with venlafaxine IR (Effexor), a drug used for the treatment of depression. The intent of this study is to test specific hypotheses regarding: 1. long-term brain effects of a single course of antidepressant treatment 2. pharmaco-conditioning effects underlying antidepressant tolerance/sensitization 3. brain functional response to initial versus subsequent antidepressant trials in normal healthy subjects.
Von Willebrand disease is an inherited bleeding disorder that impacts the blood's ability to clot properly. Von Willebrand disease is cause by the lack or not working substance in the blood known as Von Willebrand factor. Current therapy for Von Willebrand disease includes desmopressin acetate (DDAVP) and /or VWF/FVIII concentrates. Patients with severe Von Willebrand disease face a lifetime of weekly treatments and mounting medical bills. Gene therapy could help these patients improve their quality of life by providing the missing factors necessary for the blood's ability to clot properly. The gene transfer options being studied include naked DNA, viral gene transfer vectors encoding Von Willebrand factor transgenes, and ex vivo cell therapy. The latter involves transplantation of the patient's own cells modified with a corrected copy of the defective gene. Human blood outgrowth endothelial cells (BOEC) display all the properties needed for successful ex vivo cell therapy. We plan to obtain blood samples from normal research subjects and patients with Von Willebrand Disease in order to isolate blood outgrowth endothelial cells (BOEC) from peripheral blood, and develop a ex vivo gene therapy for Von Willebrand Disease.
The purpose of the study is to measure how much nitroglycerin or its metabolites may be found in the bloodstream when MQX-503 or an FDA approved Nitroglycerin ointment 2% USP is applied to the skin of healthy subjects.
The purpose of this study is to determine what effect Magnevist (gadopentetate dimeglumine) injection has on the way the heart conducts the electrical impulses that allow it to beat effectively. The study will compare Magnevist injection's effect to that of placebo (a saline injection).
This study is being done to measure the functions of the stomach after eating a meal and to develop a new method that will simultaneously measure both gastric emptying and the relaxation of the stomach after a meal using nuclear medicine testing. This would make the testing more convenient for patients and will also offer better understanding of these two gastric functions.
The primary objective of this study is to determine whether EGG readings obtained from both normal subjects and dyspeptic patients are reproducible from one EGG recording to another on a different day. The secondary objective of this study is to determine whether the EGG readings are analyzed and diagnosed consistently when reviewed and compared by multiple blinded readers when the same tracing is reviewed.
St. John's Wort is a popular dietary supplement that many people take to elevate mood or relieve stress. This study will test in normal volunteers whether this preparation may alter mood and if so, by what means. Animal studies suggest that St. John's Wort may work similarly to some antidepressants that affect levels of the chemical serotonin in the brain. Participants in this study must also be enrolled in NIMH protocol #98-M-0094 (SPECT Imaging of Dopamine and Serotonin Transporters in Neuropsychiatric Patients and Normal Volunteers) and protocol #91-M-014 (MRI Imaging of Neuropsychiatric Patients and Controls). Separate consent forms are required for each study. Candidates will undergo medical and psychiatric evaluations that may include blood and urine tests, electroencephalogram and electrocardiogram. Normal volunteers will have a mood assessment at the beginning of the study. They will then be randomly assigned to take either placebo (a pill with no active ingredient) or St. John's Wort 3 times a day for 2 weeks, and will be told what they are taking. After an 11-week hiatus, they will again start treatment on the same schedule, but will not be told which preparation they are receiving. Each evening during the 2-week treatment periods, subjects will complete a brief self-rating mood assessment questionnaire. At the end of each treatment period, they will undergo SPECT brain imaging (a type of CT scan) to determine dopamine and serotonin distribution and density in the brain. For this procedure, study subjects take three drops of potassium iodide solution within 24 hours before the scan and two drops nightly for 3 days following the procedure. About 10 ml (less than two teaspoons) of blood are drawn before a radioactive tracer is injected. SPECT imaging is done the next day. After about 1 hour of imaging, subjects are given either a placebo or St. John's Wort, and then imaging continues for another 2 hours. During the procedure, up to five blood samples of 6 ml each may be drawn. At some point during the study, a MRI scan of the brain will be done.
This protocol is being submitted to consolidate, update, and expand two previously approved protocols (77-C-0066 and 82-C-0044) into a single protocol. The purpose of this study is to examine the factors involved in the regulation of the immune system of healthy individuals and to define the abnormalities in this regulation that underlies the immunological disorders of patients with a variety of immunodeficiency and malignant disorders. The studies will include the ex vivo phenotypic and functional analysis of the network of cells involved in humoral and cellular immune responses, and in vivo testing for the capacity to make delayed-type hypersensitivity and humoral responses following immunization with a variety of antigens. Individuals to be studied will include patients with a variety of malignancies and patients with primary and secondary immunodeficiency disorders. Selected family members or family members known to be genetic carriers of certain immunodeficiency diseases as well as normal, unrelated individuals will also be studied. A small number of procedures will be used including analysis of blood obtained by phlebotomy, apheresis, skin testing and recall antigens and immunization to assess humoral immunity....
The goal of the protocol is to define the normal humoral and cellular immune responses to antigens in volunteers and to define abnormalities of these immune responses in patients with immunodeficiency diseases or cancer. In vitro assays and in vivo skin tests and immunization with antigens will be utilized.
The objective is to determine the length-tension properties of the anal sphincters using Fecobionics in normal subjects and FI patients during anal distension and during simulated evacuation. Fecobionics has the consistency and shape of normal stool and can record pressures, cross-sectional area, orientation and viscoelastic properties of the anorectum and can map the geometric profiles during evacuation, and thereby provides multi-dimensional measurements of pressures, deformability, and topographic changes. Fecobionics combines several existing tests to provide novel insight into anorectal function. The purpose for the development was to overcome the technological controversies and disagreement between various tests and unphysiological test conditions. The aim was to imitate defecation as much as possible to the natural process. Fecobionics was developed to simulate stool and to provide the driving pressure and resulting deformations of stool along with a measure of an objective anorectal angle during defecation in a single examination. Fecobionics makes it possible to describe objectively, without disturbing the defecation process, the opening characteristics and pressure signatures during initial entry into the relaxing anal canal. The overall goal is to provide mechanistic understanding of defecation in health and defecatory disorders. It exceeds previous attempts to make artificial stool for evaluation of defecation (BET and FECOM) and integrates other technologies as well. It was designed to have a consistency and deformability of Type 4 (range type 3-5) on the Bristol stool form scale. The range from types 3-5 is found in 70% of normal subjects. A major novelty is that Fecobionics measures pressures in axial direction; i.e., in the flow direction.

It is anticipated that Fecobionics will shed light on the neurophysiology of defecation in health and disease, including understanding the effect of biofeedback and neuromodulatory effect of SNS. It will be of great value to provide endpoints in normal subjects that in future studies can be objective measures for monitoring treatment efficacy. The present protocol is on normal subjects only.
