Study on Precision Dosing Strategies of Anti-infective Agents in the Very Early Stage of Kidney Transplantation
An observational study of Transplant Recipient (Kidney), run by Zhongnan Hospital.
Trial summary
This study addresses the clinical problem that reliance on serum creatinine, eGFR or empirical dosing fails to accurately adjust anti-infective doses given rapid renal function shifts within the very early 0-5 days post kidney transplantation. Read more about this study

About this study
This study addresses the clinical problem that reliance on serum creatinine, eGFR or empirical dosing fails to accurately adjust anti-infective doses given rapid renal function shifts within the very early 0-5 days post kidney transplantation. We will systematically analyze dynamic trajectories of renal biomarkers (serum creatinine, cystatin C, urine output and other renal function indices), quantify their quantitative associations with the exposure, clearance and pharmacodynamic target attainment of anti-infectives. Combined with clinical profiles, medication data, TDM results and perioperative factors, a population PK/PD model will be built for patients in the very early post-transplant stage. We will further validate the value of dynamic renal markers for individualized anti-infective dosing. This research provides evidence for shifting from static renal function-based empirical dosing to precision dosing guided by real-time renal changes and drug exposure, supporting optimized anti-infective dosage, enhanced efficacy and medication safety in early kidney transplant recipients.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
In vivo exposure of anti-infective agents (time frame: Before and after each anti-infective administration within 0-5 days after kidney transplantation). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Aug 2026.
