Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this study is to investigate the effects of ECMO-assisted therapy on L-AmB PK parameters in patients with critically ill patients of invasive fungal infections, and to determine the in vivo pharmacokinetic changes of L-AmB in the ECMO population. To establish and validate a population pharmacokinetic model for liposomal amphotericin B in patients with critically ill patients of invasive fungal infections treated with ECMO adjuvant therapy, and to explore the pharmacokinetics/pharmacodynamics of the drug with different dosing regimens.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The information of patient characteristics, physiological parameters, ECMO related parameters, administration and sampling information of L-AmB were collected.Patients were intravenously titrated after 3 doses of maintenance dose titration. The sampling window was from 0 to 24 h. The time points were 0.5 h before and 1, 2, 3, 6, 9, 12, 16, 20 and 24 h after administration. NONMEM software was applied to establish the PPK model of L-AmB.

L-AmB group

To establish and validate a population pharmacokinetic model for L-AmB in patients with severe invasive fungal infections treated undergoing ECMO-assisted therapy.

Group Type EXPERIMENTAL

Determination of blood drug concentration

Intervention Type BIOLOGICAL

Collecting blood samples from patients and determining blood drug concentrations. Patients were intravenously titrated after 3 doses of maintenance dose titration of L-AmB. The time points of sample collecting were 30 minutes before and 1, 2, 3, 6, 9, 12, 16, 20, 24 hours after administration. Then, the blood concentrations were determined according to the established method.
