Tacrolimus: Tacrolimus at the dosage reccomended by the "Clinical Pharmacogenetics Implementation Consortium (CPIC) Guidelines for CYP3A5 Genotype and Tacrolimus Dosing" based on the subjects pharmacogenetic phenotype.
Tacrolimus: Subject allocated to this arm will receive tacrolimus according to clinical practice and the drug's product labelling. These subject will not receive a personalised dose based on their pharmacogenetic phenotype.
Study summary
This is a phase IV multicentre adaptive single-blinded randomized clinical trial to evaluate if preemptively genotyping populations at pretransplant chronic kidney disease susceptible of receiving tacrolimus therapy is effective, cost-effective, and feasible within the Spanish National Health System when compared to the current standard of care. This trial is nested within the iPHARMGx master protocol.

Primary outcome measure(s)
Tacrolimus concentrations levels — 4 days Number and percentage of patients achieving tacrolimus target plasma concentrations at visit 3. Tacrolimus concentrations levels at day 4 (+/-1d) will be the effectiveness surrogate outcome. It will be considered therapeutic range levels between 7-10 ng/ml.
