Filter by:The purpose of this study is to evaluate the safety and effectiveness of levofloxacin, an antibiotic, compared with ciprofloxacin, another antibiotic, in the treatment of adults with mild to moderate infections of the skin and the supportive layers beneath the skin.
This is a randomized double-blind three-arm trial to evaluate two dosages of CVT-E002 against placebo in pediatric upper respiratory tract infections (URTI). It is hypothesized that CVT-E002 use at standard doses reduces the duration of URTI in children aged 3-12 years.
The purpose of the study is to compare the safety and effectiveness of the antibiotic levofloxacin by administering a higher dose of levofloxacin and using a shorter course of therapy.
The aim of this study is to define the etiology of intra-abdominal infections, to study the role of Enterococcus spp and Pseudomonas aeruginosa in these infections and to clarify the need for specific enterococcal antimicrobial coverage.
This is a two phase study (randomised and non-randomised phase). The randomised phase will initially examine 4 blinded doses of GW640385 boosted with rtv (with continuation of current background therapy) in comparison to an ongoing, open-labeled rtv-boosted protease inhibitor (PI) regimen for 15 days. At the Day 15 visit, all subjects will optimize background therapy. Additionally, subjects receiving the lowest dose of GW640385 will be re-randomised to one of the higher doses and subjects in the control arm will receive a new rtv-boosted PI based on resistance testing at screening. Subjects will remain in the randomized phase on one of these 4 continuing treatment arms for at least 48 weeks. An interim analysis will occur during the randomised phase to select for a dose of GW640385 to evaluate further in Phase III studies. After dose selection subjects will move to the non-randomised phase of the study. In the non-randomised phase subjects who are receiving GW640385 will be assigned to final selected dose for assessment of long term safety, tolerability, pharmacokinetics, and antiviral activity.
This study will assess the efficacy of subsequent protease inhibitor (PI)-containing therapy in subjects who have acquired HIV-1 protease mutations whilst receiving a GW433908 (fosamprenavir)-containing regimen.
Seniors are a population vulnerable to respiratory infections. It is hypothesized that regular use of COLD-fX following an influenza vaccination would potentially augment immune response in the elderly. Use of COLD-fX may also provide additional protection again respiratory infection and reduce the incidence and severity of respiratory infections in otherwise healthy seniors.
The purpose of this study is to determine the role of HIV-specific CD4 T cell responses and immune responses dependent upon these CD4 responses that develop when antiretroviral drugs are started during acute or recent HIV infection, whether these CD4 responses can be enhanced with a therapeutic HIV vaccine (HIV-1 immunogen), and what pattern of HIV-specific immune responses is associated with control of HIV upon discontinuation of antiretroviral drugs during an analytical therapeutic interruption. Participants will be treatment-naive adults with acute or early HIV infection who will choose to start or not start anti-HIV drugs at the beginning of the study. NOTE: In August 2007 we were notified by the manufacturer of the candidate vaccine that they were no longer making the vaccine, and that the vaccine would no longer be available. Unfortunately too few participants have received either the vaccine or placebo to conclude anything about efficacy. No safety problems occurred.
RATIONALE: Voriconazole and caspofungin acetate may control invasive fungal infections in patients who have weakened immune systems. PURPOSE: This phase II trial is studying how well giving voriconazole together with caspofungin acetate works in treating invasive fungal infections in patients with weakened immune systems.
Six sites of the Pediatric Inflammatory Bowel Disease Consortium (plus 2 additional sites) will participate in this study. The participating sites will be that of the Principal Investigator (PI), Emory University School of Medicine, Atlanta, GA (Benjamin D. Gold, MD); Texas Children's Hospital / Baylor College of Medicine (George Ferry, MD and Tony Olive, MD); Children's Hospital of Philadelphia, Philadelphia, PA (Bob Baldassano, MD); University of Chicago Children's Hospital, Chicago, IL (Barbara Kirschner, MD); University of California, San Francisco (Mel Heyman, MD); Mass General Hospital / Harvard University (Harland Winter, MD); V.A. Stanford University School of Medicine, Stanford, CA (David Relman, MD); Children's Center For Digestive Healthcare, Atlanta, GA (Stanley Cohen, MD); and Centers for Disease Control and Prevention, Atlanta, GA (Drs. Jeannette Guarner, Siobhan O'Connor and Thomas Shinnick) The duration of study is 2 yrs. Objectives: 1. Improve the methods to collect biopsies from the colon and ileum, tissue storage techniques and best methods to detect specific infections in children with Crohn's disease; 2. Determine if there are specific infectious agents that are more common in children with Crohn's disease, and; 3. Determine if there are types of children with Crohn's disease (e.g., children living in Boston, African American children) who may be more at risk for getting the infections. The study design involves children ages 6 months through 17 11/12 years of age who are undergoing a clinically-indicated colonoscopy. Subjects will be grouped into cases and controls. - Any child ages 6 mos through 17 11/12 years of age, undergoing a clinically-indicated colonoscopy as determined by the treating physician, is eligible for enrollment. About 500 patients will be enrolled in this study. - Cases will consist of those children within the defined age group, who are undergoing diagnostic colonoscopy and have the definitive diagnosis of Crohn's disease. - Children who have the diagnosis of indeterminate colitis or ulcerative colitis for the purpose of this R03, will be excluded as cases and from initial analysis, but will have tissue specimens banked for subsequent evaluation for infectious agents. - Controls will consists of children within the defined age group, undergoing clinically indicated colonoscopy and who are not diagnosed with Crohn's disease, ulcerative colitis or indeterminate colitis (e.g., juvenile polyps, irritable bowel syndrome or functional bowel disease). - Stool specimen (5ml/1 tsp) will be collected to test for different types of bacteria - A questionnaire will be administered to each research volunteer. - Each subject's medical information (i.e. diagnosis, disease stage, and laboratory results) will be stored electronically in a separate access-based database. A unique identifier will be assigned to each patient entered into the study and will also be used for blinding of the specimens analyzed by the pathologist and by molecular assays for infectious agents. - Colonoscopy will be performed by the treating pediatric gastroenterologist and biopsies obtained in the usual standard of care. - Clinical biopsies from the rectum, left, right, transverse colon and cecum will be placed in formalin containing vials as per standard of care for the clinical pathologist and diagnostic evaluation.
