Filter by:This study is a two-part study. Part one is designed to see how different formulations of GSK364735 are absorbed in the body and To see how food affects how GSK364735 is absorbed in the body. Part two is designed to see how repeat dosing affects how GSK364735 is absorbed in the body.
The purpose of this study is to describe respiratory syncytial virus (RSV) hospitalization rates and to begin to address the utilization of outpatient resources for RSV medically-attended lower respiratory tract infections (MALRI) in 32-35 week gestational age (GA) premature infants who are less than 6 months of age and do not receive treatment.
The primary objective of this trial is to demonstrate the equivalence, in terms of immunogenicity, of three different industrial lots of the investigational vaccine thereby supporting consistency of the manufacturing process. Secondary Objectives: Immunogenicity To demonstrate that the investigational vaccine induces an immune response at least as good as the one induced by the reference vaccine, in terms of antibody titers. To assess the immunogenicity of the investigational vaccine using parameters defined in the European Medicines Agency (EMEA) Note for Guidance (CPMP/BWP/214/96). Safety: To demonstrate that the investigational vaccine is at least as well tolerated as the reference vaccine, in terms of defined safety profile. To describe the safety profile after vaccination. Comfort of the vaccination assessment: To assess the pain immediately after the injection using a Verbal Rating Scale. To describe the vaccination comfort after the injection using a -Patient-Reported Outcome questionnaire: the Vaccination Comfort Questionnaire.
Vaccination against influenza is a high priority for the elderly population who present the highest morbidity and mortality rate. However, due to their weak antibody response an improvement of the immune response to influenza vaccination remains an unmet medical need. The purpose of an investigational influenza vaccine candidate administered by an alternate route is to improve immune responses to the vaccine in the elderly population, which could provide additional reductions in influenza-associated morbidity and mortality in this population. Primary Objective: To demonstrate that the investigational vaccine induces a better immunogenicity than the reference vaccine in terms of seroprotection rate after the first vaccination. Secondary Objectives: Immunogenicity: To describe the antibody persistence induced by both vaccines at 3, 6, and 12 months after the first vaccination in a subset of subjects. To describe the immunogenicity of the investigational vaccine after each vaccination using parameters defined in the European Medicines Agency (EMEA) Note for Guidance (CPMP/BWP/214/96) specific to elderly subjects. Safety: To demonstrate the tolerance of the investigational vaccine after the first vaccination, in terms of pre-defined solicited systemic reactions. To describe the safety profile after each vaccination. To describe the effect of repetitive injections on the safety profile.
This study will determine how best to use a vaccine for generating high levels of antibodies called immune globulins (IVIG) in people, which, in turn, can be collected and used to develop a possible treatment for avian influenza (bird flu). Immune globulins are proteins made by the body that attack the influenza virus. This study will use an experimental bird flu vaccine to stimulate immune globulin production in healthy people. The vaccine is similar to the regular influenza vaccine and has been studied in more than 450 people. This study will use high doses of the vaccine to generate high antibody levels that can be collected for producing the new treatment. Healthy adults between 18 and 60 years of age who weigh at least 110 pounds may be eligible for this study. Candidates are screened with a medical history and physical examination. Participants are given one of three doses of the vaccine, depending on when they enter the study. The first 25 people enrolled receive a dose of 90 micrograms (mcg). If this dose is well tolerated, the next 25 people receive 120 mcg, and if this dose is also well tolerated, the last 25 people receive 180 mcg. Vaccination consists of either two shots (one in the muscle of each arm) or one shot in the buttock on four occasions. Subjects are vaccinated on four occasions, each 4 weeks apart. On the day of each vaccination, subjects provide a blood sample to evaluate blood counts, chemistries, and antibody levels, and to test for HIV, hepatitis B and C, syphilis, and antibody against avian flu. For 7 days after each vaccination, subjects keep a diary card to record any symptoms, such as pain, fever, muscle aches, or others. At the end of the 7 days, they are contacted by study staff to report the symptoms. In addition to the vaccinations, subjects undergo apheresis to collect IVIG once their blood test shows moderately high antibody levels. For this procedure, blood is collected through a needle in an arm vein and flows through a catheter (plastic tube) into a machine that separates the blood cells from the antibodies and protein. The antibodies and protein are collected and the rest of the blood is returned to the body. Subjects are asked to undergo at least three apheresis procedures.
International studies have repeatedly documented a substantial prevalence of sexual risk behaviors and high rates of human immunodeficiency virus (HIV) and other sexually transmitted infections (STI) ranging from 5%-56% amongst long-distance truck drivers ("truckers") living in diverse international settings including India, Bangladesh, South Africa, China, Laos and Thailand. The prevalence of sexual risk factors and STI/HIV in US drivers is unknown. This proposal will provide both qualitative and quantitative data on HIV risk behaviors by interviewing and testing truckers working for established long-distance trucking firms, the sector which accounts for most of the jobs in the trucking and warehousing industry in the United States. The data obtained from this study will be used to inform the development of an HIV prevention intervention for long-haul truck drivers.
The purpose of this study is to evaluate the safety, tolerability and efficacy of ertapenem sodium as initial therapy for the treatment of complicated urinary tract infections, including pyelonephritis in indian adults.
This randomized controlled trial will evaluate the effect of a multifaceted intervention including performance feedback on adherence to hand hygiene among healthcare workers. A key component of the study is to demonstrate whether improved adherence to hand hygiene leads to a reduction in rates of infection.
Study Phase: IV Study Type: Open-label, multicenter, randomised clinical trial with two arms stratified for an intensified immunosuppressive regimen in patients at high risk for acute rejection. Study Description: 148 kidney transplant recipients at risk for CMV disease were randomized and treated with ganciclovir capsules for 3 months (Group A, prophylaxis, N=74) or received ganciclovir IV only in case of proven CMV viral load (Group B, preemptive therapy, N=74). Initially, a 2 months follow up was planned in this trial. However, the study group decided to offer a longterm follow up to all patients and amended the protocol, respectively. The aim of the study was to identify the most efficacious way to prevent renal transplant recipients from CMV disease and to find out, if one of these two strategies may increase graft or patient survival. Therefore, both wellknown approaches of CMV prevention were compared in two study groups: Prophylaxis (Group A): Oral primary prophylaxis with ganciclovir capsules was started directly after transplantation and performed until day 90. In case of CMV infection (proven CMV viral load) or symptomatic CMV disease, treatment with ganciclovir IV was initiated. Preemptive Therapy (Group B): No oral primary prophylaxis was given. Treatment with ganciclovir IV was given to patients with proven CMV viral load (CMV infection or CMV disease) only.
The purpose of this clinical research study is to develop observational clinical experience with the use of entecavir in participants who are either of Black/African-American race or of Hispanic ethnicity.
