Safety and tolerability of ertapenem versus ceftriaxone in a double-blind study performed in children with complicated urinary tract infection, community-acquired pneumonia or skin and soft-tissue infection☆
Introduction
Ertapenem is a group I carbapenem [1] with broad-spectrum antibacterial activity against aerobic and anaerobic pathogens, excluding meticillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas and Acinetobacter spp. Ertapenem has a high degree of in vitro activity against targeted Gram-negative and Gram-positive pathogens [1], [2], [3], [4] and is active in vitro against extended-spectrum β-lactamase-producing Klebsiella pneumoniae and Escherichia coli[5]. Ertapenem is safe and effective for adults with complicated intra-abdominal infection (cIAI), acute pelvic infection, complicated urinary tract infection (cUTI) and skin and soft-tissue infection (SSTI), including diabetic foot infections [6], and community-acquired pneumonia (CAP) [7]. It is also effective as prophylaxis for surgical site infections following colorectal surgery [8]. A recent study demonstrated the safety and efficacy of ertapenem for treating children with cIAI and acute pelvic infection where mixed infections are expected, and ertapenem offers a simplified regimen with the possibility of intramuscular dosing [9].

Study design
This randomised, double-blind, active-controlled trial, conducted at 39 international centres during 2002 and 2003, evaluated the safety, tolerability and efficacy of ertapenem versus ceftriaxone for treating children with cUTI, SSTI or CAP. Written informed consent was obtained for each patient from the legal guardian. The study was registered with ClinicalTrials.gov (Identifier: NCT00451386).
Patients
Children aged ≥3 months and <18 years with cUTI, SSTI or CAP requiring initial parenteral antibiotic
Patient accounting and demographics
Of 451 participants screened for enrolment, 47 (19 with CAP, 25 with SSTI and 3 with cUTI) were not randomised (Fig. 1). Of the 404 participants randomised, 304 were randomised to the ertapenem group and 100 to the ceftriaxone group. One child randomised to the ertapenem group did not receive any study drug (and is therefore not included in the safety analysis) and one child randomised to the ceftriaxone group withdrew consent (included in the safety analysis but not included in Table 1 as no
Discussion
This randomised, double-blind, active comparator study of 403 paediatric patients with cUTI, SSTI or CAP is, to our knowledge, the largest such study of a parenteral antibacterial in children to date. The double-blind design minimised the potential for bias, particularly in the assessment of clinical safety. These results extend the available data on ertapenem for treatment of moderate-to-severe cUTI, SSTI and CAP in a paediatric population and are consistent with the results obtained for these
