Indicated for the treatment of community-acquired pneumonia or complicated skin and soft tissue infections in neonates, infants, children, adolescents and adults1, Zinforo is a fifth-generation cephalosporin with an extended spectrum of activity* relative to third-generation compounds.2
Zinforo mode of action
Zinforo targets key pathogens in cSSTI and CAP in paediatric patients from birth. Use of Zinforo for the treatment of cSSTI or CAP in neonates and young infants aged <2 months is supported by evidence from adequate and well-controlled studies in adults, as well as pharmacokinetic and safety data from paediatric studies1,3-6
Zinforo has a safety and tolerability profile consistent with comparator therapies in clinical studies†7-12
Treat the majority of patients with simple dosing and a flexible infusion time
Identifying patients at risk of initial treatment failure is vital for appropriate selection of antimicrobial therapy as initial treatment failure increases patients’ risk of mortality in both CAP and cSSTI.**13-18
Zinforo has an extended in vitro spectrum of coverage, including key pathogens in CAP and cSSTI‡1,2,19,20

*Efficacy has been demonstrated in CAP clinical studies against the following pathogens that were susceptible to ceftaroline in vitro: Streptococcus pneumoniae, Staphylococcus aureus (methicillin-susceptible strains only), Escherichia coli, Haemophilus influenzae, Haemophilus parainfluenzae, and Klebsiella pneumoniae.1 Efficacy has been demonstrated in cSSTI clinical studies against the following pathogens that were susceptible to Zinforo in vitro: Staphylococcus aureus (including methicillin-resistant strains), Streptococcus pyogenes, Streptococcus agalactiae, Streptococcus anginosus group, Streptococcus dysgalactiae, Escherichia coli, Klebsiella pneumoniae, Klebsiella oxytoca and Morganella morganii.1
†Zinforo is contraindicated in patients with hypersensitivity to any active substance or excipient and should not be used in patients with a history of hypersensitivity to other cephalosporin-class antibiotics or who have had an immediate and severe hypersensitivity reaction (e.g., anaphylaxis to other β-lactam antibacterial agents). Fatal hypersensitivity reactions are possible.1 Antibacterial-associated colitis and pseudomembranous colitis (Clostridium difficile) have been reported including cases that were life-threatening.1Patients with a pre-existing seizure disorder should use Zinforo with caution as seizures occurred in toxicology studies at doses higher than typical human exposures.1 DAGT (Coombs test) became positive in 11.2% of patients from five pooled pivotal studies in patients who received Zinforo every 12 hours and in 32.3% of patients who received Zinforo every 8 hours. Although no patients developed haemolytic anaemia, there remains a potential risk.1 The most common adverse reactions occurring in ≥3% of patients treated with Zinforo were diarrhoea, headache, nausea, and pruritus and were generally mild or moderate in severity.1 Comparator therapies: cSSTI, ceftriaxone; CAP, vancomycin or cefazolin, plus optional aztreonam.
**There is no experience with Zinforo in the treatment of CAP in the following patient groups: the immunocompromised, patients with severe sepsis/septic shock, severe underlying lung disease, patients with PORT Risk Class V, and/or CAP requiring ventilation, CAP due to MRSA, patients requiring intensive care; the available clinical data cannot substantiate efficacy against PNSP.1 There is no experience with Zinforo in the treatment of cSSTI in the following patient groups: the immunocompromised; patients with severe sepsis/septic shock, necrotising fasciitis, perirectal abscess and patients with third-degree and extensive burns. There is limited experience in treating patients with diabetic foot infections. Caution is advised when treating such patients.1
‡Zinforo is not active against Pseudomonas aeruginosa. Like other cephalosporins, Zinforo is not active against ESBL-producing strains. In vitro activity does not always correlate with clinical efficacy.1
