Clinical study to evaluate the efficacy of fosfomycin vs meropenem in the treatment of bacteremia due to Escherichia coli (general infection caused by a specific bacteria).

Randomized, phase III, multicentre, open-labelled clinical trial, to evaluate the efficacy of fosfomycin vs meropenem in the treatment of bacteremic urinary tract infection caused by Escherichia coli producing extended-spectrum beta-lactamases (ESBL).

Design outcomes

Primary

MeasureTime frame
Secondary Objective: *To evaluate the early clinical and microbiological response in both arms. * To compare mortality and hospitalization period in the first 30 days, in patients treated with fosfomycin and meropenem. *To evaluate the safety of intravenous fosfomycin in this treatment. *To compare recurrent episodes rate(relapse or reinfection) in both arms. *Pharmacokinetics of intravenous fosfomycin in patients with bacteremic urinary tract infection by E. coli extended spectrum beta-lactamase (ESBL). *To compare the impact of fosfomycin and meropenem about the colonization in the intestinal tract by multiresistant gram-negative bacilli. *To assess the frequency of emergence resistant strains to fosfomycin and the resistance mechanisms involved. ;Main Objective: The main objective of this study is to evaluate the efficacy of intravenous fosfomycin with regard to meropenem for the treatment of bacteremic urinary tract infections caused by E. coli ESBL.;Primary end point(s): Clinical and microbiological cure occurring at 5?7 days after the end of the treatment.;Timepoint(s) of evaluation of this end point: At 5?7 days after the end of the treatment.

Secondary

MeasureTime frame
Secondary end point(s): *Early clinical recovery. *Early microbiological recovery. *Recurrent episodes (relapse or reinfection) in the fisrt 60 days. *Mortality in the first 30 days and hospitalization period. *Frecuency and seriousness of adverse events. *Fosfomycin plasmatic concentration in stationary phase (day 3). *Ratio of E. coli resistant to fosfomycin and meropenem during the treatment ; Timepoint(s) of evaluation of this end point: *Day 3 (Visit 2) *Day 5 (Visit 3) *Day 5-7 (Visit 4) *In the first 30 days *In the first 60 days
