Active clinical trials for "Bacterial Infections"

Streptococcus pneumoniae is a major cause of morbidity and mortality in children worldwide, resulting in up to 1 million pediatric deaths every year.Since the licensure of PCV7 and PCV13,the reported overall decline in invasive pneumococcal disease in hospitalized children younger than 5 years several years is approximately 60% in Western countries.This is a single center,blind, randomized, positive-controlled clinical trial.The purpose of this study is to preliminary evaluate the safety of PCV13i vaccine in subjects at age of 7 months and above,and to investigate the safety and immunogenicity of PCV13i vaccine at age of 2 and 3 months,compared to PCV13.

The purpose of this research is to determine if a new antibiotic called dalbavancin will work to treat and cure certain infections while reducing the need for daily antibiotics by vein.

The objective of this extension study is the initial assessment of safety and immunogenicity of the second dose of GBS Trivalent Vaccine following the time interval that is close to the inter-pregnancy interval observed in the general population.

To evaluate the immune response and the safety of a primary series schedule that includes V419 (PR5I) at 2 and 6 months of age and Pediacel at 4 months of age Primary objectives To demonstrate that the mixed schedule induces acceptable responses for Hepatitis B (HB) one month after completion of the mixed schedule To demonstrate that the mixed schedule induces acceptable responses for Haemophilus influenzae type b (Hib) one month after completion of the mixed schedule Secondary objectives To describe the antibody response to all PR5I antigens one month after completion of the mixed schedule To describe the antibody response to meningococcal serogroup C (MCC) conjugate vaccine one month after the second dose of MenC vaccine To describe the safety profile after each dose of study vaccines administered

This is a randomized, partially-blinded, placebo and moxifloxacin-controlled, single dose, 4-period, balanced crossover study. The primary objective of this study is to separately assess the effects of a therapeutic and supratherapeutic dose of GSK1322322 on the cardiac conduction (corrected QT interval [QTc]) compared with placebo in eligible healthy male and female subjects. Avelox (moxifloxacin hydrochloride) will be used as an open-label positive control in order to validate the sensitivity of the study in detecting QTc change. Approximately 56 healthy subjects will participate in the study for approximately 9 weeks i.e. 30 day Screening period, 4-week Treatment period, and a 7-10 day Follow-up period. There will be 4 treatment periods separated by at least 1 week. Subjects will be admitted to the clinical unit on Day -1 of each dosing period. Each subject will receive each of the four treatment sequences (GSK1322322 1200 milligram [mg] intravenous [IV] over 60 minutes x 1 dose, GSK1322322 3000 mg IV over 60 minutes x 1 dose, GSK1322322 Placebo IV over 60 minutes x 1 dose, moxifloxacin 400 mg administered orally x 1 dose) on Day 1 of each Treatment period in a randomized fashion. Twelve-lead electrocardiogram (ECG), continuous Holter monitoring, laboratory tests, vital sign measurements, and serial pharmacokinetic samples will be collected for up to 24 hours following each treatment. If no clinically significant abnormalities are noted, subjects will be discharged from the clinical research unit after the completion of all assessments on Day 2 in each period and return approximately one week later for the next dosing period. Each individual subject will follow the same dosing schedule at every period. A Follow-up visit will be conducted 7-10 days after administration of the last dose of study medication in treatment period 4.

The primary objectives of this study are to evaluate the immunogenicity and safety of concomitant administration of V419 (PR51) with 2 types of meningococcal serogroup C conjugate (MCC) vaccines to healthy infants at 3 and 4 months of age in terms of antibody seroprotection rate (SPR) to MCC. Participants also received a Haemophilus influenza type B (Hib)-MCC vaccination at 12 months of age. It was hypothesized that the SPR to MCC at 1 month post-dose 2 of either tetanus toxoid conjugated Meningo C (MCC-TT) or CRM197 conjugated Meningo C (MCC-CRM) vaccines would be acceptable when administered concomitantly with V419.

This study is being conducted to confirm that GSK1322322 has no negative impact on hormone levels and contraceptive efficacy when co-administered with a frequently prescribed oral contraceptive thereby to facilitate the use of GSK1322322 in women of child-bearing potential receiving oral contraceptive (OC) pre-infection. This study is designed to investigate steady-state plasma ethinyl estradiol (EE) and norethindrone (NE) pharmacokinetic (PK) following administration of Ortho-Novum (EE/NE) 1 tablet every 24 hours (q24h) fed with and without GSK1322322 1500 milligram (mg) q12h fed. Each subject will participate in the study for approximately 12 weeks: a 30 day screening period, 4-week run-in period, three 7 day treatment periods, and a 3-5 day follow-up period. The study is planned to enroll approximately 24 subjects (18 active/6 placebo).

The main purpose of this study is to determine if the Angiotech central venous catheter (CVC) is equal in effectiveness to a CVC coated with chlorhexidine and silver sulfadiazine in preventing bacterial catheter colonization. Other objectives of this study are to determine if the Angiotech CVC is equal in effectiveness to a CVC coated with chlorhexidine and silver sulfadiazine in preventing catheter-related local infection, and catheter-related bloodstream infection. This study will also assess the safety of the Angiotech CVC.

Primary Outcome Measures:Incidence density of colonization with MRSA or VRE (number of new colonization events per 1000 patient days at risk) during the intervention phase. Secondary Outcome Measures:The effect of the 2 strategies on the incidence density of colonization with MRSA and VRE individually will be determined and compared descriptively. The effect of the strategies on the cumulative incidence of bacteremia caused by MRSA and VRE will be determined to assess the clinical relevance of the strategy in preventing infection. The trial will evaluate the frequency of hand hygiene and the use of gloves and gowns by healthcare workers to substantiate whether the effect of the intensive control strategy is mediated, as expected, by an increase in the use of gloves and gowns due to an increase in the number of patients cared for using Contact Precautions.

Health-care-acquired infections are of tremendous importance for patients, especially catheter-associated infections. More than 40% of all bloodstream infections are associated with central venous catheters (CVC; catheters which are inserted into a large vein near the heart). Of all patients that acquire such an infection 1% to 5% die as a result from it. The insertion site is the main source of contamination and infection. In general, bacteria of the skin are the cause of infection, especially in short-term CVCs (10-14 days). Therefore it is necessary to efficiently disinfect the skin for the preparation and care of CVC insertion sites. Several substances are used for disinfection. Alcohol-based disinfectants are mainly used in Central Europe, other preparations contain povidine-iodine or chlorhexidine. Alcoholic disinfectants have a rapid initial effect, chlorhexidine shows an additional remanent (longer lasting) effect. A further substance, octenidine dihydrochloride, also demonstrated a remanent effect in a pilot study with neurosurgical patients. The purpose of our study is to compare an alcohol-based disinfectant containing octenidine dihydrochloride with a pure alcoholic disinfectant regarding efficacy and tolerability in patients receiving a CVC for a minimum of 5 days.
