Together with the mulCvariate model developed, they can be leveraged to individualize tacrolimus starCng dose. Donor age, recipient age at baseline, CYP3A phenotype and corCcosteroid treatment explained 33.5% of IIV over D8-M3 post-transplant. Donor age, recipient age at baseline, CYP3A phenotype, diabetes at baseline and ASpartate Amino Transferase (ASAT) explained 36.4% of IIV at M3-M12 post-transplant.Excluding the CYP3A phenotype resulted in a significant effect of ethnicity at all Cme periods, but with lower performance to explain tacrolimus dose requirement. No significant food-effect was found at any Cme period, whether expressed as the Cming of tacrolimus intake with respect to meals, or as a fat diet.Intra-individual variability was generally moderate over M3-M12. It was significantly lower in paCents with chronic hepaCc disorder or cancer.
