Abstract

Complicated skin and skin structure infections (cSSSIs) are common and are associated with significant health and economic costs. These infections are predominantly characterized by infection with Staphylococcus aureus, and SENTRY Surveillance data indicate that the occurrence of this pathogen in cSSSIs has increased and that almost half of the isolated pathogens are methicillin-resistant S. aureus (MRSA). Surveillance data also indicate that Gram-negative isolates are not uncommon in cSSSIs. In the past, empiric antimicrobial coverage of both Gram-positive and Gram-negative infections has generally necessitated the use of at least 2 antimicrobial agents. Ceftobiprole, a novel advanced-generation pyrrolidinone cephalosporin, is currently under review by the Food and Drug Administration as therapy for cSSSIs. This article presents a summary of the results of 2 recently published multicenter noninferiority trials involving approximately 1600 patients with a variety of cSSSIs. In the 1st trial, which included patients with Gram-positive cSSSI, the clinical cure rate at the test-of-cure (TOC) visit (the primary end point) among patients receiving ceftobiprole was 93.3%. The 2nd trial included a broad range of cSSSIs of varying pathogenicity. In this trial, the clinical cure rate among patients receiving ceftobiprole for S. aureus and MRSA infection was 94.6% and 91.8%, respectively. Ceftobiprole's capacity as a broad-spectrum agent was demonstrated in the 2nd trial, in which the clinical cure rate at TOC was 90.5% against a variety of infections and pathogens (including Gram negatives). In addition, the cure rate among patients with moderate to severe diabetic foot infection who received ceftobiprole was 86.2%, and these patients experienced a shorter length of stay in the hospital than those who received a comparator. This article also addresses the results of these trials in the context of the current medical need for safe broad-spectrum antimicrobial agents with MRSA coverage.
