Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

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
Treatment: Drugs - Vancomycin - model-based dosing regimen

Experimental: Model-based vancomycin dosing - Participants will receive model-based intermittent intravenous vancomycin dosing as calculated by the dosing calculator available on a web application. Participants will then have routine therapeutic drug monitoring and linear dose adjustments.


Treatment: Drugs: Vancomycin - model-based dosing regimen
A dosing calculator based on a population pharmacokinetic model for vancomycin will be used to generate a participant's intermittent vancomycin dosing regimen. The participant's post-menstrual age, weight, creatinine and the target trough vancomycin level will be entered into the dosing calculator and the dose will be generated (intermittent infusion, dosing frequency will be from 1 to 4 times per day according to the corrected gestational age).

Outcomes
Primary outcome [1] 0 0
The proportion of young infants achieving target trough vancomycin concentrations (10 to 20 mg/L) at the first steady-state level when using a model-based dosing regimen
Timepoint [1] 0 0
From first vancomycin dose (immediately after consent) to steady state level taken at 24-48 hours post-first-dose.
Secondary outcome [1] 0 0
The proportion of young infants with supra- (defined as >20mg/L) or sub- (defined as <10mg/L) therapeutic vancomycin concentrations at the first steady state level using a model-based dosing regimen (through a web application)
Timepoint [1] 0 0
From first vancomycin dose (immediately after consent) to steady state level taken at 24-48 hours post-first-dose.
Secondary outcome [2] 0 0
The proportion of young infants who are excluded from the study due to the model-based dosing regimen providing a total daily dose which exceeds 80 mg/kg/day despite a target trough concentration of 10 mg/L.
Timepoint [2] 0 0
From consent to calculation of vancomycin dose (immediately after consent)
Secondary outcome [3] 0 0
The frequency of drug-related adverse events (including infusion-related adverse events and nephrotoxicity).
Timepoint [3] 0 0
From first vancomycin dose (immediately after consent) to completion of vancomycin therapy (as determined by clinical team, an average of 5 days)
Secondary outcome [4] 0 0
The frequency of drug administration errors
Timepoint [4] 0 0
From first vancomycin dose to completion of vancomycin therapy (as determined by clinical team, an average of 5 days)

Summary
Brief summary
Current dosing regimens for vancomycin result in many young infants not reaching the target level of vancomycin in the blood at steady state (when the blood is in equilibrium at 24-48 hours).The purpose of this study is to assess an improved method of calculating the dose of vancomycin ('model-based dosing') in young infants with infections in order for them to achieve the target vancomycin level at steady state. A dosing calculator (which will be available through a web application) will be used for the dose calculation.
