Effectiveness and safety of once-daily tacrolimus formulations in de novo liver transplant recipients: The PRETHI study. Clin Transplant 2023; 37:e15105.

Abstract
Data comparing long-term effectiveness and safety of once-daily tacrolimus formulations in de novo liver transplantation are scarce. We compared the effectiveness, pharmacokinetic profile, and safety of LCPT (Envarsus) and PR-Tac (Advagraf) for up to 12 months post-transplant. Adult de novo liver transplant recipients who started IR-Tac (Prograf) and were converted to LCPT or PR-Tac 3-5 days post-transplant were included. Data from 163 patients were analyzed, 87 treated with LCPT and 76 with PR-Tac. The incidence of treatment failure was 30.5% in the LCPT group versus 23.0% in the PR-Tac group (p = .291). Biopsy-proven acute rejection (BPAR) was reported in 26.8% of patients in the LCPT group and 17.6% in the PR-Tac group (p = .166). Graft loss was experienced in one patient (1.2%) in the LCPT group and three patients (4.1%) in the PR-Tac group (p = .346). Death was registered in three patients (3.7%) in the LCPT group and three patients (4.1%) in the PR-Tac group (p > .999). Patients in the LCPT group showed 45.7% higher relative bioavailability (Cmin /total daily dose [TDD]; p < .01) with similar Cmin and 33.3% lower TDD versus PR-Tac (p < .01). The evolution of renal function, safety profile, and the incidence of post-transplant renal failure, dyslipidemia, obesity, hypertension, and diabetes mellitus were similar in patients treated with LCPT and PR-Tac. In de novo liver transplant patients, LCPT and PR-Tac showed comparable effectiveness with higher relative bioavailability, similar Cmin and lower TDD in the LCPT group. Renal function, safety, and post-transplant complications were comparable in LCPT and PR-Tac groups.

Effectiveness and safety of the conversion to MeltDose ® extended-release tacrolimus from other formulations of tacrolimus in stable kidney transplant patients: A retrospective study. Clin Transplant 2019; 34:e13767. [PMID: 31815310 PMCID: PMC7050537 DOI: 10.1111/ctr.13767] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2019] [Revised: 11/14/2019] [Accepted: 11/25/2019] [Indexed: 12/24/2022]
Abstract
Tacrolimus is the cornerstone of immunosuppressive therapy after kidney transplantation. Its narrow therapeutic window mandates serum level strict monitoring and dose adjustments to ensure the optimal risk‐benefit balance. This observational retrospective study analyzed the effectiveness and safety of conversion from twice‐daily immediate‐release tacrolimus (IR‐Tac) or once‐daily prolonged‐release tacrolimus (PR‐Tac) to the recent formulation once‐daily MeltDose® extended‐release tacrolimus (LCP‐Tac) in 365 stable kidney transplant recipients. We compared kidney function three months before and three months after the conversion. Three months after conversion, the total daily dose was reduced ~35% (P < .0001), and improved bioavailability and stable serum LCP‐Tac concentrations were observed. There was no increase in the number of patients requiring tacrolimus dose adjustments after conversion. Renal function was unaltered, and no cases of BPAR were reported. Reports of tremors, as collected in the clinical histories for each patient, decreased from pre‐conversion (20.8%) to post‐conversion (11.8%, P < .0001). LCP‐Tac generated a cost reduction of 63% compared with PR‐Tac. In conclusion, the conversion strategy to LCP‐Tac from other tacrolimus formulations in stable kidney transplant patients showed safety and effectiveness in a real‐world setting, confirming the data from RCTs. The specific pharmacokinetic properties of LCP‐Tac could be potentially advantageous in patients with tacrolimus‐related adverse events.
