Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
extended (prolonged) intravenous infusion of cefepime 1g over 6 hours every 12 hours for first 3 days of therapy
Intervention code [1] 3892 0
Treatment: Drugs
Comparator / control treatment
2 comparator arms.
1. cefepime at 1g infused intravenously over 5 minutes every 12 hours for first 3 days of therapy
2. 2g infused intravenously over 5 minutes every 12 hours for first 3 days of therapy
Control group
Active

Outcomes
Primary outcome [1] 5260 0
percentage of dosing interval above pharmacodynamic breakpoint during the first 12 hours of treatment determined via limited sampling of cefepime concentrations to facilitate pharmacokinetic modelling
Timepoint [1] 5260 0
At 12 hours from start of treatment
Primary outcome [2] 5261 0
percentage of dosing interval above pharmacodynamic breakpoint from 48 to 60 hours of treatment determined via limited sampling of cefepime concentrations to facilitate pharmacokinetic modelling
Timepoint [2] 5261 0
At 72 hours from the start of treatment
Primary outcome [3] 5262 0
limited sampling of cefepime concentrations along with pharmacokinetic modelling will be used to determine the full pharmacokinetic profile for cefepime in intensive care patients with sepsis
Timepoint [3] 5262 0
Limited sampling will occur on days 1 and 3 at time = 0, 5 minutes, 30 minutes, 3 hours, 6 hours, 8 hours 10 hours and 12 hours after the start of the cefepime infusion. Pharmacokinetic modelling will be completed at the end of the first 3 days of treatment (ie 72 hours after the first dose of cefepime).
Secondary outcome [1] 8867 0
Feasibility of administration of extended (prolonged) infusions of cefepime in the medical / surgical intensive care setting by the monitoring by health care professionals of the success in administering the infusions and survey by the researchers of the intravenous lines and other infusions administered during the study period.
Timepoint [1] 8867 0
Daily during the 3 day study period
Secondary outcome [2] 8868 0
daily monitoring during the study period by health care professionsals of significant clinical outcomes (duration of mechnical ventilation, length of intensive care unit and hospital stay) , and any possible relation to the use of extended (prolonged) infusions of cefepime which may be used to inform the design of future studies of extended infusions
Timepoint [2] 8868 0
hospital discharge

Eligibility
Key inclusion criteria
An adult intensive care patient who: Has been prescribed cefepime according to The Alfred Intensive Care Unit (ICU) Antibiotic Guidelines (ie. after 7 days of hospital admission and requiring empiric or directed anti-microbial treatment); Is likely to remain in ICU for at least three days from enrolment; Has an arterial line already in situ for blood sampling.
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. Any documented allergy or adverse reaction to cefepime or other cephalosporin antibiotic or significant / serious adverse reaction to other beta-lactam or monobactam antibiotics which would normally preclude the prescribing of cefepime according to the Alfred ICU Antibiotic Guidelines.
2. Moderate to severe renal impairment (calculated estimated glomular filtration ratre (eGRF) <30mL/min at enrolment) or need for continous renal replacement therapy or intermittent heamodialysis.
3. Patients with significant burns (ie. greater than 15% body surface area)
4. Patients with extracorporeal circuits (eg. extracorporeal membranous oxygenation, ventricular assist devices)
5. All transplant patients including solid organ and bone marrow transplants
6. Pregnancy
7. Inclusion in other study protocols which preclude enrolment in this study.

Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Sequentially numbered sealed envelopes will be prepared and used to randomise patients at enrolment.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A computer generated randomisation table prepared by a statistician will be used.
Masking / blinding
Open (masking not used)
