Active clinical trials for "Gram-Positive Bacterial Infections"

The purpose of this study is to determine whether telavancin (TD-6424, ARBELIC) can be safety administered to patients with bloodstream infections and whether telavancin is effective in treating these infections.

The incidence and prevalence of nontuberculous mycobacteria (NTM) infections have gradually increased over the years worldwide (1-3). In China, Mycobacterium avium complex (MAC) was the most prevalent NTM specie (4), while challenged by long treatment duration, frequent drug-induced adverse events, lack of treatment alternatives, poor treatment outcome and high recurrence rate (5, 6). In order to maximize the efficacy of the few available drugs and prevent the development of drug resistance, ensuring adequate plasma drug concentrations are of importance. Despite the role of pathogen susceptibility, determined by minimum inhibitory concentration (MIC), is non-negligible, the evidences regarding its association with treatment outcome are limited, especially for rifamycin and ethambutol. The difficulties in explaining the clinical values of MIC might partially be attributed to the lack of in vivo drug exposure data, which cannot be accurately predicted by the dose administered because of between-patient pharmacokinetic variability (7). Therapeutic drug monitoring (TDM) is a strategy to guide and personalize treatment by measuring plasma drug concentrations and pathogen susceptibility, which might have the potential to improve treatment response to MAC lung disease. In this observational study, the hypothesis is that the drug exposure and/or MIC of antimycobacterial drugs are correlated to the treatment response of MAC lung disease, which is assessed from the perspective of treatment outcome, mycobacterial culture negative conversion, lung function, radiological presentation and self-reported quality of life. Consenting adult patients with culture-positive MAC lung disease will be recruited in study hospital. Respiratory samples (sputum and/or bronchoalveolar lavage fluid) will be collected regularly for mycobacterial culture on the basis of BACTEC MGIT 960 system and MIC will be determined using a commercial broth microdilution plate. Drug concentrations will be measured at 1 and/or 6 months after treatment initiation using liquid chromatography tandem mass spectrometry (LC-MS/MS). The final treatment outcome is recorded at the end of MAC treatment and defined according to an NTM-NET consensus statement (8).

The main purpose of this study is to find out whether changing the hospital policy to allow switch from glycopeptide antibiotics (given by intravenous drip), to an equally effective oral antibiotic (linezolid) will enable patients who are otherwise well enough to be discharged from hospital sooner. The secondary objectives are To identify those patients who could potentially be discharged on an oral agent from those being treated with a glycopeptide, thus helping target this approach most effectively To evaluate the cost involved and compare this with the costs that would have taken place if use of an oral agent and discharge had not occurred.

This study will treat patients who have a short term central catheter that is thought to be infected with a specific bacteria (gram positive bacteria)

The purpose of this study is to evaluate safety, tolerability, pharmacokinetic characteristics and efficacy of TNP-2092 in adults with ABSSSI suspected or confirmed to be caused by gram-positive pathogens.

The purpose of this study is to determine whether contezolid acefosamil is as safe and effective as linezolid in the treatment of adult patients with acute bacterial skin and skin structure infections

To assess the onset of action of linezolid

To evaluate the safety and efficacy of tigecycline in the treatment of selected serious infections caused by VRE. The primary efficacy endpoint will be the clinical response for all subjects.

Purpose: To provide a mechanism for the emergency use of tigecycline in the appropriate clinical situations.

Serious infections caused by resistant bacteria are becoming more of a medical problem throughout the world. One of the ways to deal with this problem is to develop new drugs that can control these bacteria. This study will measure how well TD-6424 (Telavancin) can control infections and whether this drug can be safely given to patients.
