Background: There is very limited evidence on the pharmacokinetic (PK) and clinical outcomes, comparing a generic tacrolimus with the standard reference drug in transplant (Tx) setting. The SparTacus (NCT01649427) study was designed to evaluate the PK profile and clinical data of tacrolimus Hexal® vs. Prograf® in de novo kidney Tx recipients (KTxR).
Methods: A total of 76 de novo KTxR were randomized in this prospective, two-phase open-label study to receive either tacrolimus Hexal® (n=35) or Prograf® (n=41), both in combination with enteric-coated mycophenolate sodium + corticosteroids + induction therapy with basiliximab. Starting dose of tacrolimus was 0.15 mg/kg/day, adjusted to target trough levels (C0) of 8–12 ng/mL from Tx to month (M) 1; 5–10 ng/mL up to M3; and 5–8 ng/mL up to M6. Primary objective (phase I) was to demonstrate comparable PK of tacrolimus Hexal® vs Prograf® as assessed by the ratio of the AUC0-12h over a period of 1-M post-Tx. Here we present the PK results at M1 along with efficacy and safety data at M6.
Results: Of 76 patients, 44 patients had an evaluable PK profile on Day 3, 10 and M1 and were included in PK analysis (tacrolimus Hexal®, n=23; Prograf®, n=21). A total of 73 patients were included in safety analysis (tacrolimus Hexal®, n=35; Prograf®, n=38). At M1, PK parameters: dose-normalized tacrolimus 12-h-AUC (h/103xL), Cmax (1/103xL), and mean 12-h tacrolimus C0 ([mu]g/L) were comparable between the treatment arms. At M6, tacrolimus Hexal® vs Prograf® had comparable incidence of composite events and its individual components (biopsy-proven acute rejection, graft loss, or death). Incidence of adverse events (AEs) and serious AEs were comparable between the treatment groups.
Conclusion: Tacrolimus Hexal® and Prograf® in de novo KTxR had a similar PK profile with comparable efficacy and safety.
