Outcome Measures
Primary Outcomes (3)
Evaluation of T(Max) for Envarsus XR, Astagraf XL and Prograf.
Tacrolimus whole blood concentrations obtained from the central lab was used for PK analysis. Actual sampling times was used to calculate T(max). Nominal time points used were: Prograf sampling strategy (21 samples): Pre-dose (C0) and then 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 12.5, 13, 13.5, 14, 14.5, 15, 16, 18, 20, and 24. Envarsus XR sampling strategy (18 samples): Pre-dose (C0) and then 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12, 14, 16, 18, 21, 24, and 27. Astagraf XL sampling strategy (17 samples): Pre-dose (C0) and then 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12, 14, 16, 18, 21, and 24.

Envarsus XR sampling strategy (18 samples): Pre-dose (C0) and then 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12, 14, 16, 18, 21, 24, and 27. Astagraf XL sampling strategy (17 samples): Pre-dose (C0) and then 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12, 14, 16, 18, 21, and 24.

Envarsus XR sampling strategy (18 samples): Pre-dose (C0) and then 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12, 14, 16, 18, 21, 24, and 27. Astagraf XL sampling strategy (17 samples): Pre-dose (C0) and then 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12, 14, 16, 18, 21, and 24.
