E.5 End points |
E.5.1 | Primary end point(s) |
Emergence of any of the two following events (see suggested definitions below):
Colonisation or infection with C. difficile, and/or colonisation or infection with Enterobacteriaceae resistant to extended-spectrum cephalosporins (cefotaxime and/or ceftazidime).
|
Förekomst av minst en av följande två händelser i tarmens mikrobiota efter avslutad intravenös behandling av studieläkemedlet:
• Kolonisation eller infektion med Clostridium difficile.
• Kolonisation med Enterobacteriaceae resistent mot cefalosporiner med utvidgat spektrum.
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
After the last dose of study drug, prior to any de-escalation therapy (Sample 2). |
Efter avslutad behandling med studieläkemedel (prov 2). |
|
E.5.2 | Secondary end point(s) |
Clinical endpoints:
• Clinical efficacy of temocillin compared to cefotaxime in the treatment of febrile UTI, 7-10 days after discontinuation of antibiotic treatment (parenteral and oral).
• Bacteriological cure per patient and per pathogen.
• Early clinical response, Day 4.
• Rate of patients with diarrhea (≥ 3 loose stools per day) during treatment and up to 7-10 days after discontinuation of antibiotic treatment (parenteral and oral).
• Frequency adverse events during the study period.
Microbiological endpoints:
• Difference between treatment groups in each of the two separate endpoints comprising the composite primary endpoint above.
• Decreased susceptibility among intestinal Enterobacteriaceae to of the study drugs over time.
• Difference between treatment groups in each of:
- Shift of dominating Enterobacteriaceae from E. coli to non-E. coli (e.g. Klebsiella, Enterobacter, Citrobacter spp.)
- Overgrowth (increased relative frequency of) of Candida spp,
- Overgrowth (increased relative frequency of) of Enterococcus spp.
