NCT03317093COMPLETEDPhase 2Ceftobiprole is a very active new cephalosporin on staphylococci resistant to methicillin (SEMR: Staphylococcus epidermidis Resistant to Meticillin, SAMR: Staphylococcus aureus Resistant to Meticillin) and / or vancomycin; it is also very active on pneumococci resistant to penicillin and / or 3rd generation cephalosporins. This new drug has AMM in nosocomial respiratory infections, Animal work shows the efficacy of ceftobiprole in gram negative bacillus meningeal infections. The rationale of this study is based on the antibacterial spectrum of ceftobiprole, which would therefore be useful in the treatment of staphylococcal bacterial meningitis resistant patients (SEMR or SAMR) encountered in intensive care and / or neurosurgery and in the treatment of pneumococcal meningitis. To validate these possibilities, it is necessary to know the concentrations of ceftobiprole in the meningeal space.
