NCT03751332

Brief Summary

Conversion of renal transplant recipients from either tacrolimus or cyclosporin A to tacrolimus modified release to investigate the effects of the MDR1/CYP450 genotype on the trough blood levels of tacrolimus with modified galenic (tacrolimus MR4; Advagraf®).

Outcome Measures

Primary Outcomes (1)

  • Effects of the MDR1 genotype on the trough blood levels of tacrolimus with modified galenics (tacrolimus MR4; Advagraf®)

    Effects of the genotype on the concentration/dose ratio (\[ng/mL\]/\[mg/d\])

    12 months

Study Arms (1)

Conversion from either CSA or TAC

OTHER

Tacrolimus with modified galenic (tacrolimus MR4; Advagraf®) once daily. In patients treated with ciclosporin A, the initial dose will be 0.1 - 0.12 mg tacrolimus MR4 per kg of body weight per day with oral morning administration. In patients who are already treated with Prograf, the conversion to Advagraf will be performed in a 1:1 ratio.

Drug: Tacrolimus

Interventions

Conversion from either cyclosporin or tacrolimus to tacrolimus modified release

Conversion from either CSA or TAC
