A Multicenter Non-inferiority Randomized Trial Comparing Cloxacillin Versus Cefazolin Efficacy for the Treatment of Bacteremia Caused by Methicillin-susceptible Staphylococcus Aureus (MSSA)
In Brief
A clinical study evaluating Cloxacillin and Cefazolin for Bacteremia Due to Methicillin Susceptible Staphylococcus Aureus. Completed, enrolled 315 participants across 1 site.
Detailed Summary
"Methicillin-susceptible Staphylococcus aureus (MSSA) bacteremia remains a major cause of community- or hospital-acquired bloodstream infections with an overall mortality estimated around 25%. Anti-staphylococcal penicillins (APs) such as oxacillin or cloxacillin are recommended as first-line agents. With the exception of first-generation cephalosporin (1GC) such as cefazolin, no alternative has yet proven a similar efficacy. Due to an unfavourable safety profile for high doses used in severe infection, an uneasy dosing schedule in patients with renal failure and possible recurrent stock-out events for APs, alternative to APs are needed. This led to propose an open-label, randomized, controlled parallel groups, phase IV, non-inferiority trial comparing the efficacy, the safety, and the ecological impact of cefazolin versus cloxacillin for the treatment of MSSA bacteremia in adults. The primary objective is to compare the therapeutic efficacy of cefazolin vs cloxacillin at day 90 after the inclusion. "

Interventions
Intravenous treatment by cloxacillin, 25 to 50 mg/kg every 4 or 6 hours, without doing less than the minimum daily dose of 8 g/day and without exceeding the maximum daily dose of 12 g/day, administered as a 60-minutes infusion. This treatment will be administered for at least 7 days by intravenous route. Dosing regimen will be adapted in patients with chronic renal failure (glomerular filtration rate below 30ml/min/1.73m²) and in patient with impaired hepatic function associated with renal impairment whatever the level of the estimation of the glomerular filtration rate, according to SPC.
Intravenous treatment by cefazolin, 25 to 50 mg/kg every 8 hours (without exceeding the maximum daily dose of 6 g/day), administered as a 30-minutes infusion. This treatment will be administered for 14 days by intravenous route. Dosing regimen will be adapted in case of glomerular filtration rate between 30-50ml/min according to SPC. As currently recommended, investigators will be encouraged to use the intravenous route for the entire duration of treatment. However, in order to interfere as little as possible with usual practice in each center, the antimicrobial therapy will be let to the choice of the physician in charge of the patient after a minimum of 7 days of intravenous treatment.
