Clearance & Pharmacokinetics of Antibiotics in Renal Replacement Therapy

Status Completed

Clinical Trial Summary

This is an observational study that evaluates the dialysis clearance and pharmacokinetics of antibiotics with different protein-bound levels in patients receiving renal replacement therapy. Meropenem, vancomycin and ceftriaxone are selected to represent three typical protein-bound levels, and the primary dialysis methods being studied are intermittent hemodialysis(IHD) and hemodiafiltration(HDF). During and after the dialysis, the drug levels in both plasma and spent dialysate are monitored, but no changes are made to therapy. The study will provide detailed information on the characteristics of the removal kinetics of the three antibiotics during dialysis, and evaluate whether the dosing regimens are the most appropriate to achieve therapeutic targets while minimizing the risk of toxicity.

Clinical Trial Description

This prospective, single-center observational study is taken to evaluate the dialysis clearance and pharmacokinetics of antibiotics with three different protein-bound levels in patients receiving renal replacement therapy. As is known that the plasma protein binding rate affects the distribution, metabolism and elimination of the drug in the body, and is also an important factor affecting the removal during dialysis, the study selects meropenem, vancomycin and ceftriaxone, of which the protein-bound levels are respectively 2%, 55% and 85%, to represent three typical protein-bound levels. The primary dialysis methods being studied are intermittent hemodialysis(IHD) and hemodiafiltration(HDF). The dialysis pattern, the antibiotic choice and its dosage for each subject are made on clinical grounds. A total of 16 milliliters of blood and 60 milliliters of spent dialysate are collected from each subject for each dialysis pattern. The study will provide detailed information on the characteristics of the removal kinetics of the three antibiotics during dialysis, and evaluate whether the dosing regimens are the most appropriate to achieve therapeutic targets while minimizing the risk of toxicity. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
