简要总结

This study will assess the pharmacokinetics, safety, and tolerability of single and multiple doses of intravenous ceftazidime-avibactam in hospitalized infants and neonates from 26 weeks gestation to 3 months of age. In Part A of the study all patients will receive a single dose of ceftazidime-avibactam. In Part B all patients will received multiple doses of ceftazidime-avibactam. Efficacy will be assessed in the infants and neonates receiving multiple doses of ceftazidime-avibactam.

排除标准

•Exclusion Criteria (All Subjects):
•Investigator site staff members directly involved in the conduct of the study and their family members, site staff members otherwise supervised by the Investigator, or subjects who are Pfizer employees, including their family members, directly involved in the conduct of the study.
•Participation in another clinical study involving investigational drug(s) within 30 days prior to study entry and/or during this study participation or have previously participated in the current study or in another study of CAZ-AVI (in which an active agent was received).
•Use of potent inhibitors of organic anion transporters OAT1 and/or OAT3 (eg, probenecid, p-aminohippuric acid (PAH), or teriflunomide) are prohibited.
•This prohibition of OAT1 and/or OAT3 inhibitors also applies to the mothers of any neonates or infants who are breast feeding during the trial.
•Other acute or chronic medical or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the Investigator, would make the subject inappropriate for entry into this study.
•Documented history of any hypersensitivity or allergic reaction to any beta-lactam antibiotic.
•Refractory septic shock within 24 hours before screening that does not resolve after 60 minutes of vasopressor therapy.
•Moderate or severe renal impairment defined as serum creatinine greater than or equal to 2 times the upper limit of normal (ULN) for age OR urine output less than 0.5 mL/kg/h (measured over at least 8 hours) OR requirement for dialysis.
•Deterioration of renal function after enrollment during Part B of the study will be handled on a case-by-case basis in discussion with the Medical Monitor.
•Evidence of progressively fatal underlying disease, or life expectancy of less than or equal to 60 days.
•Documented history of seizure.
•Active acute viral hepatitis or acute hepatic failure.
•Known Clostridium difficile associated diarrhea.
•Any condition (eg, cystic fibrosis, urea cycle disorders), antepartum/peripartum factors, or procedures that would, in the opinion of the Investigator, make the subject unsuitable for the study, place a subject at risk, or compromise the quality of data.
•Treatment with ceftazidime within 12 hours of CAZ-AVI administration.
•Exclusion Criteria for Part A Subjects Only:
•Subject received a blood or a blood component transfusion within 24 hours of the start of CAZ AVI infusion.
•Subject is expected to be discharged less than 24 hours after the start of CAZ AVI infusion.
•At study entry, subject has confirmed or strongly suspected infection with a pathogen known to be resistant to CAZ-AVI or only a Gram-positive pathogen or viral, fungal, or parasitic pathogens as the sole cause of infection.
•Confirmed or suspected CNS infection (meningitis, brain abscess, subdural abscess etc.)
•Anticipated need for antibacterial therapy longer than 14 days (osteomyelitis, endocarditis etc.).
•This applies to both study treatment with CAZ AVI as well as adjunctive IV antibacterial treatment for suspected co infection with Gram positive organisms or multi drug resistant Gram negative organisms.
•Receipt of more than 24 hours of non study systemic antibacterial treatment for Gram negative organisms after culture and before administration of study doses of CAZ AVI.
•Empiric coverage with an aminoglycoside for suspected multidrug resistant organisms is permitted, provided CAZ AVI is initiated within 24 hours after culture.
