Official title: Tacrolimus and Risk Factors for Glucose Metabolism Disorders in Kidney Transplant Patients

Run by Chiesi Poland Sp. z o.o. · NCT06833463 · Data updated 2026-11-12

This study tests whether how quickly adults break down tacrolimus affects their risk of developing prediabetes or diabetes after a kidney transplant.

Is this trial a fit for you?

Likely a good fit

Adults (age ≥18) who received a single-organ kidney transplant, are placed on standard immunosuppression including LCP tacrolimus started at transplant or converted by day 8, and do not have diabetes at enrollment are ideal candidates.

Probably not a fit

People with pre-existing diabetes, kidney retransplantation or multi-organ transplants, or those on chronic drugs that affect carbohydrate metabolism are unlikely to benefit from this study's findings.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is an observational study of adult kidney transplant recipients treated with LCP tacrolimus (Envarsus®) as part of standard immunosuppression. Researchers will measure tacrolimus blood concentrations and dosing to calculate a concentration-to-dose ratio and classify patients as faster or slower metabolizers. They will then track new problems with glucose metabolism (such as prediabetes or diabetes) in patients who did not have diabetes at enrollment. Patients must start LCP tacrolimus on the day of transplant or convert to it by day 8 according to routine care at participating Polish transplant centers.

Why it matters

Potential benefit: If successful, the findings could help clinicians personalize tacrolimus dosing to lower the chance of new-onset glucose problems after kidney transplant.

How similar studies have gone: Previous research has linked tacrolimus to new-onset diabetes and suggested metabolism rate affects toxicity, but applying LCP tacrolimus concentration-to-dose profiling specifically to predict post-transplant glucose disorders is relatively underexplored.
