About this study
Official title: Observational Prospective Multidirectional Study on the Safety of Antimicrobial Pharmacotherapy in Intensive Care Unit (ICU) Children Aged 0-17
Changes in the metabolic ability of cytochrome P-450 during child development can affect both bioavailability and elimination depending on the involvement of intestinal and hepatic metabolic processes. The age-related variability of cytochrome P-450 isoenzymes in children has been described since 2010. The variability in the development of the activity of specific cytochrome P-450 isoenzymes illustrates why the pharmacogenetic features of the medicine use at different age periods should be studied for individual drugs. This will provide an understanding of the mechanisms for preventing adverse events appearing in pediatric intensive care units while more common antimicrobial pharmacotherapy is administered. Improved knowledge of the pharmacogenetic characteristics of cytochrome P-450 and the unintended consequences of modulation of its isoenzymes could provide an understanding of the susceptibility to adverse events in children in critical conditions staying at Intensive Care unit (ICU).
Read the detailed description
An observational prospective multidirectional study on the safety of antimicrobial pharmacotherapy in ICU children aged 0-17. The endpoints of the safety assessment are the frequency of adverse events with antimicrobial agents (AMA); electrocardiography (ECG), fibrinogen concentration, international normalized ratio (INR) and prothrombin index (IPT) at screening and at the end of the treatment course, and pharmacogenetic indicators (a more detailed study of the safety profile). A demonstration of the effectiveness of each of these comparisons of inequality will be based on the hypothesis testing approach, according to which the null hypothesis concludes that there is no difference between groups receiving different AMA combinations for the endpoint of interest; and an alternative hypothesis supposes a difference between treatment groups receiving different AMA combinations. Changes in the sequential organ failure assessment (SOFA) scale in dynamics compared to the baseline will be analyzed using the Mixed-Effect Model Repeated Measure (MMRM) model which assume the baseline, gender, age, AMA combination, and the duration of the AMA course. For a population of subjects aged 0-3 months, the analysis will be performed using the analysis of covariance (ANCOVA) model with the effects of INR, fibrinogen, and IPT values at the initial level for gender, age, and AMA combination in the treatment groups.
To assess the secondary endpoint for the general population - the frequency and timing of the transition to de-escalation at ICU, cluster analysis will be conducted to identify the relationship of specific AMA combinations with the possibility of de-escalation in ICU children.
Studies will be conducted to reveal the relationship in gene polymorphism encoding isoenzymes of the cytochrome P-450 biotransformation, and the relationship between the activity of transport proteins with the indicators of effectiveness and safety of antimicrobial pharmacotherapy. The lack of pharmacological safety studies in children administered medicine combinations to overcome pan-resistant gram-negative infection provides relevant prerequisites for this study.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Changes in the metabolic ability of cytochrome P-450 during child development can affect both bioavailability and elimination depending on the involvement of intestinal and hepatic metabolic processes. The age-related variability of cytochrome P-450 isoenzymes in children has been described since 2010. The variability in the development of the activity of specific cytochrome P-450 isoenzymes illustrates why the pharmacogenetic features of the medicine use at different age periods should be studied for individual drugs. This will provide an understanding of the mechanisms for preventing adverse events appearing in pediatric intensive care units while more common antimicrobial pharmacotherapy is administered. Improved knowledge of the pharmacogenetic characteristics of cytochrome P-450 and the unintended consequences of modulation of its isoenzymes could provide an understanding of the susceptibility to adverse events in children in critical conditions staying at Intensive Care unit (ICU).
Detailed description
An observational prospective multidirectional study on the safety of antimicrobial pharmacotherapy in ICU children aged 0-17. The endpoints of the safety assessment are the frequency of adverse events with antimicrobial agents (AMA); electrocardiography (ECG), fibrinogen concentration, international normalized ratio (INR) and prothrombin index (IPT) at screening and at the end of the treatment course, and pharmacogenetic indicators (a more detailed study of the safety profile). A demonstration of the effectiveness of each of these comparisons of inequality will be based on the hypothesis testing approach, according to which the null hypothesis concludes that there is no difference between groups receiving different AMA combinations for the endpoint of interest; and an alternative hypothesis supposes a difference between treatment groups receiving different AMA combinations. Changes in the sequential organ failure assessment (SOFA) scale in dynamics compared to the baseline will be analyzed using the Mixed-Effect Model Repeated Measure (MMRM) model which assume the baseline, gender, age, AMA combination, and the duration of the AMA course. For a population of subjects aged 0-3 months, the analysis will be performed using the analysis of covariance (ANCOVA) model with the effects of INR, fibrinogen, and IPT values at the initial level for gender, age, and AMA combination in the treatment groups.

The lack of pharmacological safety studies in children administered medicine combinations to overcome pan-resistant gram-negative infection provides relevant prerequisites for this study.
