Filter by:This is an open-label, multi-center, two-part, parallel-design study to assess the PK, safety, and tolerability of TR-701 FA and its active metabolite, TR-700, following a single oral dose (Part A) or IV dose (Part B) of TR-701 FA in 12 to 17 year old adolescent patients.
Retapamulin, a topical pleuromutilin antibiotic, is the first in a new class of topical antibiotics approved for human use. In the United States (US), retapamulin is approved for the treatment of impetigo in persons nine or more months of age and was launched on 12 April 2007. This five-year study is designed to examine use of retapamulin in the pediatric population less than nine months of age. We will conduct an annual assessment of prescription sales claims for retapamulin using the Integrated Health Care Information Services (IHCIS) National Managed Care Benchmarked Database. For each year of reporting, the observed frequencies of the exposure, with or without same-day, co-prescribed sales claim of mupirocin, will be identified. The study objectives are to determine the frequency of retapamulin sales in a representative US population stratified by the designated age group and to determine the frequency of same-day sale of the topical agent, mupirocin.
Observational: studies in human beings in which biomedical and/or health outcomes are assessed in pre-defined groups of individuals. Subjects in the study may receive diagnostic, therapeutic, or other interventions, but the investigator does not assign specific interventions to the subjects of the study.
This is a Phase II, multi-center, randomized, double-blind study comparing the safety and efficacy of two doses of BC-3781 versus vancomycin in patients with acute bacterial skin and skin structure infection.
Infants and children under two years are the group with the highest rates of iron deficiency anemia. Provision of sufficient dietary iron to this age group is a challenge, and in-home iron fortification of complementary foods using micronutrient powders can be an effective approach. However, WHO has recently cautioned against untargeted use of in-home micronutrient powders that contain the entire iron RDA for a child in a single dose in areas with high rates of infections from malaria and diarrheal disease. Therefore, in this study, we will investigate the effect on the infant gut microbiota of a low dose (ca. 25% of the RDA) of highly bioavailable iron, provided by a micronutrient powder added to a complementary food. The study aim is to determine if in-home fortification using an iron-containing micronutrient powder in Kenyan infants will improve iron status and/or modify the composition and metabolic activity of the gut microbiota. Active surveillance will be done weekly to monitor the health of the infants. Our study will be done in a subgroup (n=160) of a larger double-blind controlled feeding trial in which 330 infants will be randomized to receive a micronutrient powder containing either 2.5 mg iron or no iron for 1 year. In our substudy, the infants will be studied only over the first 6 months of the 1 year intervention. Blood samples, taken at baseline and after 6 months will be used to define the iron status and the anemia level of the infants. Stool samples (2 at baseline before intervention, 6 throughout the study and additional samples in case of diarrhea) will be obtained for analysis of the gut microbiota. In the entire study (n=330), we will measure changes in iron status over 1 year.
The approach we will use is to employ measurement of the activation of white blood cells, to look at patterns of responses during a controlled infection of the gut with Mycobacterium bovis. M. bovis can be conveniently obtained in a safe and pure form as an oral vaccine. By giving three challenges of M bovis to the gut, we will simulate repeated gut infections with this organism. We can then compare the activation of cells in the blood to the immune responses seen after each challenge, to determine whether the non-specific defences of the gut can block each subsequent infection.
The aim of the study is to explore the distribution of antibiotics in the brain after an acute brain injury because brain infections treatment is still an health care problem.
To assess the relative bioavailability of two different batches of Frademicina® drug product, containing 500 mg lincomycin hydrocloride, manufactured by Pfizer Laboratories Ltd. The formulations' comparative bioavailability after oral administration will be assessed based on the statistical comparisons of the relevant pharmacokinetic parameters, obtained from the drug concentrations in the blood. The lincomycin hydrocloride concentration will be measured by a proper and validated analytical method.
GSK945237 belongs to the Bacterial Type II Topoisomerase Inhibitor (BTI) class of antibiotics. GSK945237 has demonstrated in vitro and in vivo activity against Gram positive [including methicillin resistant Staphylococcus aureus (MRSA)] and Gram-negative pathogens associated with respiratory tract, skin and soft tissue infections including isolates resistant to existing classes of antimicrobials. This study will be conducted in four (4) parts, with a single oral dose being explored in Part A (2400 mg) and repeat oral doses (b.i.d. and q.d.) being explored in Part B. Parts C and D will be optional evaluations of repeat oral doses of linezolid and a comparative evaluation of the effect of GSK945237 and moxifloxacin, respectively. Parts A and B will be single-blind, randomized, placebo-controlled, dose-rising (Part B only) studies of healthy subjects to evaluate the safety, tolerability and pharmacokinetics of GSK945237. The proposed doses range from 400 mg to 2400 mg. Part C will be a single-blind, randomized, and placebo-controlled repeat dose evaluation of 600 mg (b.i.d.) of linezolid. Part D will be a single-blind, randomized, placebo-controlled, two period crossover study. The proposed doses for Part D will be 1200 mg GSK945237 and 400 mg moxifloxacin.
This is a research study designed to look at the pharmacokinetics (distribution, breakdown, and removal) and tolerability of a single dose of daptomycin in patients aged 3 months to 24 months who have proven or suspected infections that are caused by a specific group of bacteria (called Gram-positive bacteria)or perioperative subjects that are receiving prophylactic antibiotics .
