OBJECTIVE The purpose of this study was to assess the pretherapy microbiology and fluoroquinolone susceptibility of pathogens from 650 patients with complicated urinary tract infection (cUTI) or acute pyelonephritis (AP) as part of a multicenter, randomized, controlled clinical trial. METHODS In this post hoc analysis of a multicenter, randomized,(More)
OBJECTIVE A double-blind, noninferiority trial was conducted to establish the safety and efficacy of a once-daily, 5-day course of levofloxacin 750 mg compared to a twice-daily, 10-day course of ciprofloxacin in complicated urinary tract infections (cUTI) and acute pyelonephritis (AP). This report focuses on subjects with AP. RESEARCH DESIGN AND METHODS(More)
OBJECTIVES A clinical study was conducted to compare the efficacy and safety of levofloxacin 750 mg once daily for 5 days to ciprofloxacin twice daily for 10 days for the treatment of complicated urinary tract infections (cUTI) or acute pyelonephritis (AP). METHODS A multicenter, double-blind, randomized, noninferiority study enrolled subjects with AP or(More)
INTRODUCTION Enactment of the Food and Drug Administration Amendments Act of 2007 (FDAAA) authorized the FDA to require manufacturers to submit Risk Evaluation and Mitigation Strategy (REMS) when it was deemed necessary to ensure that a drug's benefit outweigh its risk. REMS apply to new drug applications (NDAs), abbreviated new drug applications (ANDAs)(More)
OBJECTIVE Pseudomonas aeruginosa is a difficult-to-treat bacterial pathogen often isolated from patients with serious nosocomial infections. The goal of this analysis is to present the clinical and microbiologic effectiveness of doripenem in the treatment of infections due to P. aeruginosa. RESEARCH DESIGN AND METHODS A meta-analysis was conducted on the(More)
OBJECTIVE To compare the safety and efficacy of levofloxacin 750 mg QD for 2 weeks or levofloxacin 750 mg QD for 3 weeks to levofloxacin 500 mg QD for 4 weeks in treating chronic bacterial prostatitis (CBP). RESEARCH DESIGN AND METHODS This was a randomized, multicenter, double-blind, noninferiority study. The primary efficacy end point was investigator(More)
OBJECTIVE To determine the clinical and microbiologic efficacy of levofloxacin for the treatment of subjects with pneumonia caused by multidrug-resistant (MDR) Streptococcus pneumoniae (MDRSP) and non-MDRSP strains. RESEARCH DESIGN AND METHODS A pooled analysis was conducted using data from ten clinical studies in pneumonia: five comparative studies and(More)
BACKGROUND Ventilator-associated pneumonia (VAP) is classified as early-onset or late-onset, in part, to identify subjects at risk for infection with resistant pathogens. We assessed differences in the bacterial etiology of early-onset versus late-onset VAP. METHODS Subjects enrolled in 2004-2006 in 2 clinical studies of doripenem versus imipenem or(More)
The US FDA Amendments Act of 2007 was signed into law on 27 September 2007. A provision of this law granted the FDA new powers to enhance drug safety by requiring the pharmaceutical industry to develop Risk Evaluation and Mitigation Strategies (REMS). REMS are deemed necessary when a question exists as to whether the benefits of a drug outweigh its risks.(More)
OBJECTIVE To determine the proportion of subjects with oropharyngeal streptococci resistant to either levofloxacin or azithromycin prior to and during antibacterial exposure, and to follow temporal changes in the proportion of resistant and susceptible isolates through 6 weeks post-exposure. This randomized, open-label, single-center study is registered(More)
