Late-onset Sepsis in Term and Pre-term Neonates and Infants up to 3 Months of Age

This was a multicenter, open-label, single-arm, multiple-dose study of intravenous (IV) ceftobiprole medocaril (prodrug of the active moiety ceftobiprole). It could be combined with ampicillin and/or an aminoglycoside based on the Investigator's judgement according to manufacturer's instructions and/or local standard of care.

Following screening, ceftobiprole was administered as a 2-hour infusion at a dose of 7.5 mg/kg every 12 hours to 15 mg/kg every 8 hours, depending on age and weight.

The target treatment duration was 3-10 days, which could be extended to 14 days if considered clinically necessary by the Investigator.
