The main objective is to demonstrate that Envarsus® (test drug) has superior (higher) oral bioavailability compared with Advagraf™ (comparator drug) at 12 weeks after kidney transplantation. The trial also aims to compare the practicability (handling) of the two drugs using a series of pharmacokinetic parameters and to explore the relationship between drug bioavailability and long-term clinical outcomes, with a special focus on dose-dependent adverse reactions, measured until 3 years post-transplantation.
