Staphylococcus aureus is the predominant Gram-positive bacteria associated with many infections, including complicated skin and skin structure infections (cSSSI) and is carried by approximately 25 percent to 30 percent of the
According to the American Diabetes Association (ADA), nearly 21 million Americans suffer from diabetes.7 Diabetic foot infections can develop in the skin, muscle, or bones of the foot as a result of the nerve damage and poor circulation associated with diabetes. A recent
Ceftobiprole belongs to a class of antibacterial agents known as cephalosporins, which are used to treat serious infections caused by Gram-negative and Gram-positive bacteria. In clinically evaluable patients, 500mg of ceftobiprole administered intravenously every eight hours (500mg IV q8h) demonstrated an 86.2 percent cure rate compared to an 81.8 percent cure rate seen with the combination of 1g of vancomycin administered intravenously every 12 hours (1g IV q12h) plus 1g of ceftazidime administered intravenously every eight hours (1g IV q8h).
Diabetic foot infections are becoming increasingly difficult to treat, said study author, Gary J. Noel, MD, franchise medical leader of anti-infectives for Johnson & Johnson Pharmaceutical Research & Development, L.L.C. These data suggest that ceftobiprole may be useful as stand-alone therapy for this increasingly common type of complicated skin infection.
The use of ceftobiprole in adults for the treatment of complicated skin and skin structure infections, including diabetic foot infections (without concomitant osteomyelitis, an infection of the bone or bone marrow), is under regulatory review in the United States, Europe, Switzerland, Australia and Canada. These data, along with the regulatory submissions, demonstrate the ongoing commitment of Johnson & Johnson Pharmaceutical Research & Development, L.L.C., to developing novel drugs for the anti-infective market.
In a Phase III, multi-center, double-blind trial, 257 patients with diabetic foot infections without concomitant osteomyelitis, were randomized to receive either 500mg of ceftobiprole administered intravenously every eight hours (500mg IV q8h) or 1g of vancomycin administered intravenously every 12 hours (1g IV q12h) plus 1g of ceftazidime administered intravenously every eight hours (1g IV q8h). Severity of diabetic foot infections among the 257 patients varied. Severity was mild (grade 2) in 27 percent, moderate (grade 3) in 59 percent, and severe (grade 4) in 13 percent of trial patients. Additionally, 67 percent of patients were microbiologically evaluable. The most common pathogens associated with these infections were MSSA (37 percent), MRSA (15 percent), E. cloacae (9 percent), S. agalactiae (8 percent), P. mirabilis (8 percent), and P. aeruginosa (8 percent).
Ceftobiprole was well tolerated and the incidence of adverse events in ceftobiprole-treated patients were similar to the incidences that were observed in the vancomycin plus ceftazidime-treated patients.
