Model Informed Precision Dosing (MIPD) integrates clinical data to optimize dosing for patients with unstable pharmacokinetics, like those with hematologic malignancies or critical illnesses. This study aims to create a pharmacokinetic model for teicoplanin, addressing complex dosing challenges and improving therapeutic outcomes through MIPD-driven recommendations.

concentration of teicoplanin
In recent years, there has been a trend towards not only monitoring drug concentrations but also incorporating clinically significant data into mathematical models to provide recommended dosages with improvement of clinical treatment outcomes, known as Model Informed Precision Dosing (MIPD). The purpose of MIPD is to address the challenges faced by patients with unstable pharmacokinetics, such as those with hematologic malignancies or critical illnesses. These patients often struggle to achieve stable drug concentrations due to various factors, leading to suboptimal therapeutic effects. Both hematologic malignancy and critically ill patients are prone to infections. Since pathogens are difficult to diagnose early, the primary strategy is to administer broad-spectrum antibiotics that cover Gram-positive bacterial infections. Teicoplanin, a glycopeptide antibiotic, is used to treat infections caused by Gram-positive bacteria, including Staphylococcus aureus. However, due to its long elimination half-life (83\~182 hours), It has been a clinical challenge to determine the appropriate dosage. Additionally, these two patient groups often exhibit hypoalbuminemia and unstable renal function. Since teicoplanin is highly protein-bound (90-95% bound) and primarily excreted by the kidneys (97% excretion), optimal dosing recommendations require therapeutic monitoring to achieve better treatment outcomes. Recommended target of therapeutic drug monitoring was established by the Japanese Society of Infectious Diseases in 2022. The targeted pharmacokinetic pharmacodynamic parameter is the 24 hours area under the curve to minimum inhibitory concentration (AUC24/MIC). Since MIPD software to estimate AUC of teicoplanin is not available in many institutions, achieving the trough level target is recommended. Our previous study found that, following a loading dose regimen of 12 mg/kg/dose every 12 hours for three doses, followed by a fourth dose at the 24th hour, hematologic malignancy patients achieved the best therapeutic effect if the trough level reached ≥18.85 mcg/ml at 48 hours. This research aims to retrospectively construct a population pharmacokinetic model by using data from hematologic malignancy patients. Moreover, it will prospectively apply MIPD concept to provide optimal clinical dosage recommendations for hematologic malignancy or critically ill patients and subsequently analyzing the outcomes.
