Ceftobiprole (Zeftera/Zevtera) is a fifth-generation[2] cephalosporin antibiotic with activity against methicillin-resistant Staphylococcus aureus, penicillin-resistant Streptococcus pneumoniae, Pseudomonas aeruginosa, and enterococci.[3][4][5] It was discovered by Basilea Pharmaceutica[6] and was developed by Johnson & Johnson Pharmaceutical Research and Development.[7] It has been shown to be statistically noninferior to the combination of vancomycin and ceftazidime for the treatment of skin and soft tissue infections.[8]

It has been described as a fifth-generation cephalosporin,[9][10] though acceptance for this terminology is not universal.

Pharmacology[edit]

Like other cephalosporins, ceftobiprole inhibits bacterial growth by blocking penicillin-binding protein, a key enzyme involved in cell wall synthesis. Ceftobiprole inhibits the 2a penicillin-binding protein (PBP) of methicillin-resistant Staphylococcus aureus and the 2x PBP of Streptococcus pneumoniae,[4] as well as the classic PBP-2 of MSSA. Ceftobiprole is resistant to staphylococcal β-lactamase.[6]

Mode of administration[edit]

Ceftobiprole is given intravenously; it cannot be given by mouth.

Regulatory approvals[edit]

Ceftobiprole has been approved for use in Canada, Switzerland, and the European Union.[11] It is under review by regulatory authorities in the United States, Australia, Russia, and South Africa.[12] In November 2008, the US FDA declined to approve ceftobiprole, citing data integrity concerns with two of the supporting studies,[13] and prompting Basilea to sue Johnson & Johnson for breach of license agreement on February 2009.[14]

Synonyms[edit]

  • RO0639141-000[6]
  • BAL9141[15]
  • Ceftobiprole medocaril
