Who can take part
You may be able to join if
- Participant must be from birth to <18 years of age. Participants up to 2 months must have been born at term or preterm with a gestational age ≥32 weeks.
- Sufficient intravascular access (peripheral or central) to receive study intervention.
- Written informed consent from parent(s) or other legally acceptable representative(s), and informed assent from participant (if age appropriate according to local regulations).
- If female and has reached menarche, or has reached Tanner stage 3 development, (even if not having reached menarche) the participant is authorized to participate in this clinical study if the following criteria are met: i. Participant has a negative urine and/or serum human chorionic gonadotropin test at screening visit. As serum tests may miss an early pregnancy, relevant menstrual history, and sexual history, including methods of contraception, should be considered ii. Participant agrees to avoid conception from the time of screening until 7 days after receipt of study intervention and agrees not to attempt pregnancy from the time of screening until 7 days after EOT with study intervention, and participant agrees to follow guidelines received regarding continuation of abstinence, initiation of abstinence or about allowed contraception, and iii. Participant reports sexual abstinence for the prior 3 months or reported the use of at least 1 of the acceptable methods of contraception, including an intrauterine device (with copper banded coil), levonorgestrel intrauterine system or regular medroxyprogesterone injections, or participant agrees to initiate sexual abstinence from the time of screening until 7 days after end of treatment (EOT) with study intervention.
- Participant has a clinically suspected and/or bacteriologically documented complicated urinary tract infection (cUTI) or acute pyelonephritis judged by the investigator to require the participant to be hospitalized for treatment with intravenous (i.v.) therapy.
- The causative pathogen is confirmed to be either susceptible to cefepime (if results are available) or suspected to be susceptible to cefepime-enmetazobactam, and the patient is suitable for treatment with cefepime according to the investigator judgement.
You likely can't join if
- History of serious allergy, hypersensitivity (e.g., anaphylaxis), or any serious reaction to cefepime, any cephalosporin, penicillins, β-lactamase inhibitors (e.g., tazobactam, sulbactam, or clavulanic acid), or other βlactam agents
- Participant is considered unlikely to survive the 6-week study period or had a rapidly progressive illness, including septic shock, that was associated with a high risk of mortality.
- At the time of first study intervention administration, known presence of a cUTI caused by pathogens resistant to Cefepime - enmetazobactam.
- Presence of any of the following clinically significant laboratory abnormalities: a. Haematocrit <25% or haemoglobin <8 g/dL (<80 g/L, <4.9 mmol/L) for children ≥ 1 month, or <13 g/dL (<130 g/L, <8.0 mmol/L) for children < 1 month. b. Serum alanine aminotransferase (ALT) or aspartate aminotransferase (AST)>3 times the age-specific upper limit of normal (ULN), or total bilirubin >2 times ULN (except known Gilbert’s disease) and Absolute Neutrophil count<1000/ mm3 . c. eGFR <30 mL/min/1.73m2 . (updated creatinine-based “Bedside Schwartz” equation (Schwartz et al. 2009))
- Participant has baseline QTcB (corrected Bazett’s formula) of greater than 450 msec.
- History of seizures, excluding well-documented febrile seizures of childhood.
