A Single Center Four Part Study in Healthy Adult Subjects to Evaluate: the Safety, Tolerability and Pharmacokinetics of a Single Oral Dose and Repeat Escalating Oral Doses of GSK945237; the Effect of Linezolid on Hematology Safety Parameters; and the Effe

Summary

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.

A Study To Assess The Effect Of Linezolid On QTc Interval

The FDA has asked Pfizer to assess the risk of linezolid on QT interval (obtained from ECG readings) which could predispose patients to ventricular arrhythmias. This study is conducted to...

Moxifloxacin in Preventing Bacterial Infections in Patients Who Have Undergone Donor Stem Cell Transplant

RATIONALE: A donor stem cell transplant can lower the body's immune system, making it difficult to fight off infection. Giving antibiotics, such as moxifloxacin, may help prevent bacterial...

The purpose of this study is to evaluate the safety and efficacy of omadacycline as compared to linezolid in the treatment of adults with acute bacterial skin and skin structure infections...

Study to Compare Lefamulin to Moxifloxacin (With or Without Linezolid), for the Treatment of Adults With Pneumonia

This study evaluates the safety and efficacy of lefamulin, a pleuromutilin, for the treatment of adults with moderate to severe community-acquired bacterial pneumonia.

Safety and Efficacy of CEM-102 Compared to Linezolid in Acute Bacterial Skin Infections

The purpose of this study is to determine the safety and efficacy of CEM-102 compared to Linezolid in the treatment of acute bacterial skin structure infections (ABSSIs).
