Trial Review

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

Description of intervention(s) / exposure
Open label pharmacokinetic study of meropenem and tazocin in septic patients requiring slow low efficiency dialysis (SLED) with haemodiafiltration (HDF).
Both the dialysis therapy and antibiotic therapy will be administered regardless of enrolment.
The pharmacokinetic study relates to a single SLED-HDF session, where the antibiotic (meropenem or tazocin) has been administered intravenously prior to the start of the dialysis session. Samples are then taken to measure antibiotic concentrations over time during the dialysis session. Where possble the pharmacokinetic study will be repeated during the next dialysis session which may be 24 or 48 hours later, depending upon the patient's clinicall status.

Outcomes
Primary outcome [1] 296083 0
Determination of pharmacokinetics of meropenem or tazocin for septic patients requiring SLED-HDF for the treatment of their acute kidney injury.
The pharmacokinetics of these drugs on SLED-HDF will be estimated using a population pharmacokinetic approach with the standard software NONMEM (ver 7.2.0).
Timepoint [1] 296083 0
Timed sampling across a dialysis session.
Baseline pre-antibiotic dose, then at 15min, 30min, 60 min, 2hours post antibiotic but pre-SLED-HDF.
Commencement SLED-HDF. Blood samples at 15 min, 30 min, 45 min, 60 min, 2hours, 4hours and 6 hours and then immediately prior to next dose.
Blood samples wil be taken before and after dialysis membrane.
Dialysate samples: baseline, 30 mins, 60 mins, 2 hours, 4 hours, 6 hours.
Urine samples (if not anuric). Baseline, 0-2hours (predialysis). 0-2 hours on dialysis, 2 - 6 hours on dialysis (before next dose of antibiotic).
Each participant will undergo 2 pharmacokinetic clearance studies on SLED-HDF. These will be separated by at least 24 – 48 hours as SLED-HDF is usually scheduled on alternate days.

Eligibility
Key inclusion criteria
Any septic ICU patient, treated with meropenem or tazocin who requires SLED-HDF for the treatment of their acute kidney injury
Minimum age
18 Years
Maximum age
80 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
The next of kin do not consent to particpation. (Rarely will the individual be able to give consent as they will be ventilated and sedated).
Intensivist deem the participant is not suitable for the study on clinical grounds.

Statistical methods / analysis
There is no data on the pharmacokinetics of meropenem or tazocin for patients on SLED-HDF, so a power calculation is not appropriate. By repeating the clearance studies for each patient twice, we assume that with 5-6 participants we will have sufficient data to undertake the pharmacokinetic modeling.
