Brief Summary

TEMO-CARB is a phase 3, randomized, controlled, multicentre, open-label pragmatic clinical trial to test the non-inferiority of temocillin versus carbapenem as initial intravenous treatment of Urinary Tract Infection (UTI) due to extended-spectrum beta-lactamase (ESBL) producing enterobacteriaceae.

Detailed Description

Urinary tract infections are among the most common bacterial infections that are treated in the community by an empirical antibiotic treatment regimen. Enterobacteriaceae are the most common bacteria involved in urinary tract infection. Since 2006, extended-spectrum beta-lactamase (ESBL) producing enterobacteriaceae have spread in France, as elsewhere. Finding therapeutic alternatives to carbapenems in infections caused by ESBL producing enterobacteriaceae is imperative. Although temocillin, 6-Ξ±-methoxy derivative of ticarcillin has been suggested as a potential alternative to carbapenem therapy for ESBL related infections, it was not investigated in accordance with current standard. The hypothesis to test in this study is that temocillin is not inferior to a carbapenem as initial intravenous treatment of urinary tract infections caused by ESBL producing enterobacteriaceae.

Exclusion Criteria
  • Patient infected with a bacteria which is not an ESBL-producing enterobacteriaceae.
  • Polymicrobial infection.
  • Hypersensitivity and/or previous intolerance to carbapenem or temocillin, or penicillins or any other beta-lactam.
  • Patient with a contraindication to any of the drugs to be used in research
  • Patient presenting another site of infection than urinary (except onset of bacteraemia from urinary tract origin due to Gram negative bacteria).
  • Woman who is pregnant, breastfeeding, or expecting to conceive at any time during the study (pregnancy test will be conducted for woman without menopause).
  • Palliative care of life expectancy < 90 days.
  • Ongoing empirical treatment of the urinary tract infections with carbapenem or temocillin > 24 hours before randomization
  • Delay in randomization > 48 hours after identification of ESBL producing enterobacteriaceae in urinary and/or blood culture.
  • Participation in other clinical trial for the infection.

Primary Outcome Measures
NameTimeMethod
Clinical and microbiological cure5-7 days after end of treatment

The primary endpoint, was defined as achieving both clinical cure and microbiological eradication of all baseline pathogens 5-7 days after completion of treatment.

Clinical cure is defined as complete resolution, substantial improvement or return to pre-infections signs and symptoms of complicated lower urinary tract infections or pyelonephritis without the need for additional antibiotic therapy Microbiological efficacy will be assessed by quantitative urine culture and defined as follows \< 10\^3 Colony Forming Unit (CFU)/mL of the baseline pathogens

Secondary Outcome Measures
NameTimeMethod
Clinical recurrences60 days after randomization

Relapse: new symptoms of urinary tract infection in a patient previously considered as clinically or microbiologically cured in the visit 5-7 days after treatment completion plus positive urine Β± blood culture grows the same microorganism isolated that in the initial culture.

Re-infection: same definition but with different strain in urinary culture

Mortality60 days after randomization

Death for any reason or for infectious events

Frequency of oral antibiotic switch in both arms (temocillin vs. carbapenem)60 days after randomization
Length of hospital stay60 days after randomization

Time from randomization to hospital discharge

Persistent cure rate60 days after randomization

Clinical cure is defined as complete resolution, substantial improvement or return to pre-infections signs and symptoms of complicated lower urinary tract infections or pyelonephritis without the need for additional antibiotic therapy

Microbiota impact studyTime Frame : 5-7 days after treatment completion

Study treatment impact in the gut colonization with multidrug Gram negative bacilli) and temocillin resistant Gram negative bacilli

Early microbiological eradication3-4 days after randomization

Microbiological eradication will be assessed by quantitative urine culture and defined as follows \< 10\^3 colony forming unit Colony Forming Unit (CFU)/mL of the baseline pathogens
