Swiss approval for Zevtera in treatment of complicated skin and soft tissue infections

Nov 13 2008

Swissmedic, the Swiss agency for therapeutic products, has approved Zevtera (ceftobiprole medocaril) for the treatment of complicated skin and soft tissue infections, including diabetic foot infections which have not spread to the bone.

Ceftobiprole is licensed from and co-developed with Basilea Pharmaceutica Ltd. Janssen-Cilag will market ceftobiprole in Switzerland under the trade name Zevtera. Swiss based Basilea Pharmaceutica Ltd will co-promote the drug in key European markets and North America.

Ceftobiprole is the first, broad-spectrum, anti-MRSA cephalosporin antibiotic with activity against a range of difficult-to-treat Gram-positive and Gram-negative hospital- and community-acquired pathogens including methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa. In clinical trials, ceftobiprole has demonstrated high cure rates in patients with complicated skin infections, including those caused by the potentially deadly MRSA.

Data from the European Antimicrobial Resistance Surveillance System (EARSS) show that the prevalence of MRSA - a difficult to treat cause of hospital-and- community acquired infections - while varying considerably among countries, has been rising across Europe for the past six years.

The use of ceftobiprole in adults for the treatment of complicated soft tissue infections, including diabetic foot infections which have not spread to the bone, is under regulatory review in United States, Australia and in the European Union among other countries. In Canada, ceftobiprole was launched in August 2008 under the trade name Zevtera.

Complicated skin and soft tissue infections are among the most common infections in the hospital setting. Staphylococcus aureus is the predominant pathogen in these infections. In recent years, resistant strains, such as MRSA have become increasingly common and have been associated with increased morbidity and mortality. New broad-spectrum antibiotics that cover resistant bacteria such as MRSA, but also clinically important and problematic Gram-negative pathogens, address a high-unmet medical need in the treatment of severe skin and soft tissue infections.

Patients with chronic wounds or those who have recently received antibiotics may also be infected by Gram-negative pathogens. This is frequently the case for diabetic patients with foot infections. Adequate treatment of diabetic foot infections can require hospitalization, surgery and broad-spectrum intravenous antibiotics.

Ceftobiprole, the first anti-MRSA cephalosporin to be approved, is an intravenous antibiotic that belongs to the class of antibacterial drugs known as cephalosporins, which are used to treat serious infections caused by a broad range of bacteria, characterized as Gram-negative and Gram-positive, based on a classification process that is used to identify the specific type of bacteria.

Phase III clinical trials have demonstrated that ceftobiprole is clinically efficacious against the following pathogens: Enterobacter cloacae, Enterococcus faecalis, Proteus mirabilis, Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus agalactiae, Streptococcus pyogenes, Escherichia coli, Klebsiella pneumonia and Pseudomonas aeruginosa.

The Janssen-Cilag company have a long and successful track record in developing and marketing treatments for a wide variety of conditions such as infectious disease, HIV, pain management, fungal infections, multiple myeloma, gastroenterological disorders, epilepsy, Alzheimer's disease, schizophrenia, acute bipolar mania, behavioural psychological symptoms of dementia, disruptive behaviour disorders, and autism.
