Vancomycin for Sepsis
(VAST-i Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial examines whether personalized dosing models for vancomycin, an antibiotic, can improve treatment for children with sepsis. Sepsis is a severe infection, and the trial aims to determine if these new dosing methods can maintain optimal vancomycin levels—not too high or too low. By adjusting doses based on each child's kidney function, the trial seeks to treat infections effectively while minimizing side effects. Children admitted to an ICU with sepsis, who are on a ventilator or require medication for blood pressure, might be suitable candidates for this study. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants a chance to contribute to groundbreaking medical research.
Do I need to stop my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
Is there any evidence suggesting that vancomycin is likely to be safe for children with sepsis?
Research has shown that vancomycin is generally safe when carefully monitored. About 90% of patients can be successfully treated with the right dose, typically between 40-60 mg per kilogram of body weight per day. Most people handle the drug well at these levels.
However, some risks exist. About 20% of patients might experience a negative reaction to the medicine, known as an adverse drug event (ADE). The risk of kidney problems increases if vancomycin levels in the blood become too high. Specifically, if the lowest concentration in the bloodstream, called the trough level, exceeds 15 mg/L, the risk of sudden kidney issues can triple.
The trial is in its early phase, focusing on understanding the safety of vancomycin for children with sepsis. At this stage, less safety information is available compared to later stages of research.12345Why are researchers excited about this trial?
Researchers are excited about this trial because it explores a new way to personalize vancomycin dosing for sepsis patients. Unlike standard treatments that use a one-size-fits-all approach, this method uses a personalized pharmacokinetic model that adjusts doses based on individual patient needs, specifically incorporating levels of urinary NGAL to guide adjustments. This approach aims to optimize effectiveness and minimize kidney damage, potentially leading to better outcomes for patients.
What evidence suggests that personalized vancomycin dosing could be effective for sepsis?
This trial will evaluate a personalized vancomycin pharmacokinetic model for dose adjustments in patients with sepsis. Studies have shown that personalized methods for vancomycin dosing enhance treatment accuracy. These methods predict the correct vancomycin levels in the blood, reducing the risk of kidney damage from excessive medication or ineffective treatment from insufficient dosing. A predictive method, such as one using machine learning, accurately estimates the vancomycin levels needed for effective treatment. Research indicates that personalized dosing can achieve target vancomycin levels that effectively combat infections while minimizing side effects. This approach promises improved sepsis management.678910

What Are the Treatments Tested in This Trial?
Interventions
- Vancomycin
Trial Overview
The study tests whether personalized dosing adjustments of vancomycin in children with sepsis can achieve effective blood levels without causing kidney injury, by accounting for each child's unique metabolism.

Experimental Treatment
Enrolled patients who are prescribed vancomycin by the clinical team will transition to the study-determined empiric vancomycin dosing at the time of enrollment, 12mg/kg/dose administered as an extended intravenous (IV) infusion over 2 hours given every 6 hours. Urinary neutrophil gelatinase-associated lipocalin (NGAL) will be measured as soon as possible after enrollment. Dosage adjustments will be made using the personalized vancomycin pharmacokinetic (PK) model incorporating the NGAL level once resulted. Daily urinary NGAL will be measured while on vancomycin therapy and in the intensive care unit (ICU) to evaluate for ongoing changes in renal function that may necessitate further dosage adjustments using the personalized vancomycin PK model, until clinically stabilized. Patients will undergo vancomycin area under the curve (AUC) monitoring with three timed blood draws for vancomycin concentrations with each vancomycin dosing change with a goal AUC target range of 400-600.
