Brief Summary

This study will evaluate the safety, pharmacokinetics and efficacy of ceftobiprole in term and pre-term newborn babies and infants up to 3 months of age with late-onset sepsis (LOS). Ceftobiprole is an antibiotic which belongs to a group of medicines called 'cephalosporin antibiotics'. It is approved for its use to treat adults and children with pneumonia in many European and non-European countries.

Detailed Description

This is a multicenter, open-label, single-arm, multiple-dose study of intravenous (IV) ceftobiprole medocaril (prodrug of the active moiety ceftobiprole). It may 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 will be 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 is 7-10 days, which may be either extended to 14 days if considered clinically necessary by the Investigator or may be may be stopped after 5 days at the discretion of the Investigator based on resolution of signs and symptoms of sepsis and blood inflammation markers, in accordance with local standard of care.

Primary Outcome Measures
NameTimeMethod
Safety and tolerability by incidence of adverse events (AEs) and serious adverse events (SAEs)Up to 5-7 weeks

Descriptive statistics of AEs, SAEs, deaths, and discontinuations due to AEs during treatment with ceftobiprole

Number of participants with clinically relevant findings in laboratory testsUp to 5-7 weeks

Descriptive statistics of clinical laboratory tests (including hematology, blood chemistry, urinalysis) and the change from baseline to each post-baseline visit value will also be summarized

Number of participants with clinically relevant findings in vital signsUp to 5-7 weeks

Descriptive statistics of vital signs findings including body temperature, respiratory rate, pulse rate, and systolic and diastolic blood pressures

Number of participants with clinically relevant findings in physical examinationUp to 5-7 weeks

Descriptive statistics of physical examination findings including examination of general appearance, skin, head, neck, eyes, ears, nose, throat, cardiovascular system, thorax/lungs, abdomen, lymph nodes, extremities, and nervous system

Secondary Outcome Measures
NameTimeMethod
Observed plasma concentrations of ceftobiprole, ceftobiprole medocaril, and open-ring metaboliteAt day 3

Descriptive analyses of these concentrations will be summarised by timepoint for term and pre-term neonates with post-natal age up to 3 months.

Clinical response5-7 weeks

Clinical cure rate at the end of treatment (EOT) at day 3-14 and test of cure (TOC) at 7-14 days after last ceftobiprole dose visits in the Intent-to-Treat (ITT) and Clinically Evaluable (CE) populations

All-cause mortalitythrough Day 28

All-cause mortality (ITT population)

Microbiological response5-7 weeks

Microbiological eradication or presumed eradication rate at the EOT and TOC visits (in the Microbiological Intent-to-Treat \[mITT\] and Microbiologically Evaluable \[ME\] populations)

Number of participants with improved signs and symptoms of LOSAt the Day 3 and up to 5-7 weeks

Improved signs and symptoms of LOS (including fever, hypothermia, abnormal heart rate, signs of impaired circulation, petechial rash or sclerema neonatorum, respiratory distress, gastrointestinal distress, irritability, lethargy and/or muscular or arterial hypotonia) will be assessed at Day 3, EOT, and TOC visits (ITT and CE populations)
