- Allocation: RandomizedIntervention Model: Crossover AssignmentIntervention Model Description: Once enrolled, patients will be randomized 1:1 to immediate release tacrolimus that the patient had been maintained on prior to the study (twice daily formulation) or Envarsus XR® using a permuted block randomization sequence to improve the likelihood of balance between groups. Following randomization, and independent of the formulation of tacrolimus, each patient will have a "run-in" period of 14 days to optimize the dose to reach a tacrolimus trough level within their therapeutic target. Randomization will be stratified based on each patient's follow-up period post-transplant in 2 stratification groups.Masking: None (Open Label)Primary Purpose: Treatment
Participation Requirements
- Age
- Between 13 years and 20 years

This is a randomized, prospective, single-center, pilot study assessing once daily Envarsus XR® medication efficacy, adverse events, medication non-adherence, patient-reported outcomes, and abbreviated pharmacokinetics/ dose finding to evaluate a population of adolescent renal transplant recipients while on stable tacrolimus (twice daily) and then after conversion to Envarsus XR® to provide critical efficacy, safety, dose-finding, adherence, and patient reported outcome data that could lead to adoption of Envarsus XR® as a mainstay of pediatric/adolescent post-transplant immunosuppression. Following randomization, and independent of the formulation of tacrolimus, each patient will have a "run-in" period of 14 days to optimize the dose to reach a tacrolimus trough level of 4 to 10 ng/ml. Drug Administration: After randomization (to either twice daily tacrolimus or once daily Envarsus ®) and the "run-in" period, patients will be continued on their assigned tacrolimus formulation for 4 months. He/she will then be then switched to the opposite tacrolimus formulation. Following the switch, there will be a 14 day run-in period to establish the optimal trough level (4-10 ng/ml) (analogous to the first run-in period) and then continued on that tacrolimus formulation for 4 months. Pharmacokinetics: Irrespective of whether a patient starts on Envarsus XR® after randomization or is switched to Envarsus XR® after 4 months of immediate release tacrolimus, the dose of Envarsus XR® will be determined by using a dose conversion ratio targeting 0.7 (but may range from 0.66-0.8 because of dosage strengths of Envarsus XR® dosing formulations) relative to the immediate release formulation that he/she was receiving as maintenance.
