Influence of Once-daily Versus Twice-daily Immunosuppressant on Renal Transplant
Study Details
Study Description
Brief Summary
The main objective of this study was to compare the drug compliance in patients after renal transplantation under once or twice-daily tacrolimus-based immunosuppressive regimen.
The rationale for this study is to access the influence of once-daily prolonged-release tacrolimus versus standard twice-daily tacrolimus on drug compliance in renal transplantation recipients base on the assumption that once-daily dosing regimen may help to improve drug compliance.

Detailed Description
This study will be a prospective, two-arm randomized and open-label, phase IV study to compare the drug compliance in patients under prolonged-release once-daily tacrolimus versus standard twice-daily tacrolimus based regimen after de novo renal transplantation.
The investigators will evaluate the drug compliance of the patients under once or twice-daily tacrolimus-based regimen using the medication scale BAAIS® (basal assessment of adherence with immunosuppressive medication scale)

Outcome Measures
Primary Outcome Measures
- basal assessment of adherence with immunosuppressive medication scale [12 months]
We will evaluate the drug compliance of the patients under once or twice-daily tacrolimus-based regimen using the medication scale BAAIS® (basal assessment of adherence with immunosuppressive medication scale)
Secondary Outcome Measures
- serum creatinine level [12 months]
We will evaluate the serum creatinine level of the patients enrolled in this study.
- graft survival [12 months]
We will evaluate the graft survival of the patients enrolled in this study.
- patient survival [12 months]
We will evaluate the patient survival of the patients enrolled in this study.
