No prospective or randomized clinical trial has confirmed these findings, and there is no consensus on how to adjust linezolid dosing to achieve optimal drug concentrations.\n\nObjectives: The primary objective is to determine if model-informed precision dosing optimizes linezolid dosing to achieve therapeutic trough concentrations compared to a standard dose. Secondary objectives include assessing the PK\u002FPD profile, investigating the prevalence of linezolid resistance among gram-positive bacteria, assessing microbiological resolution of infection, and evaluating the safety and tolerability of linezolid.\n\nMethodology: This study is an open, monocentric pilot randomized controlled trial with two arms: standard dose therapy versus dose adjustment based on model-informed precision dosing using therapeutic drug monitoring and PK\u002FPD targets developed in TMDx software.\n\nSample Size: 28 patients, 14 in each group. Assumptions are based on only 25% of patients in intensive care achieving the optimal therapeutic range with standard dosing, compared to an expected 80% achieving this with model-informed precision dosing.\n\nSelection Criteria: Adult patients (18+ years) already starting linezolid treatment for gram-positive infections, expected to require treatment beyond the next calendar day. Exclusions include imminent death, expected or confirmed pregnancy, expected linezolid treatment of less than 4 days or more than 4 weeks.\n\nOutcomes: The primary endpoint is defined as the difference in the proportion of patients in the intervention and in the control groups who maintained a trough linezolid concentration of 2 to 7 mg\u002FL on Day 7 and Day 13.",[57],"Gram-Positive Bacterial Infections",[22,59,60],"PK-PD Model","TDM","NOT_YET_RECRUITING","2024-05-30",{"date":64,"type":65},"2024-06-06","ACTUAL",{"date":67,"type":51},"2024-09-01",{"date":69,"type":51},"2026-06-30",{"name":5,"class":6}]
