Once-daily LCP-Tacro MeltDose tacrolimus for the prophylaxis of organ rejection in kidney and liver transplantations.

Tacrolimus is a cornerstone of the immunosuppression regimen for prevention of allograft rejection in kidney and liver transplantations, with efficacy proven in many clinical trials. The currently available and extensively used tacrolimus formulations are flawed by large inter- and intra-individual variability, low bioavailability, wide peak-to-trough fluctuations and a narrow therapeutic index. Drug delivery technology can significantly impact the pharmacologic action of a drug, influencing its pharmacokinetic and subsequent therapeutic profile. LCP-Tacro is a novel, prolonged-release, MeltDose(®) formulation of tacrolimus designed for once-daily administration. A hallmark differentiation between this formulation and other once- and twice-daily tacrolimus products is the proprietary MeltDose drug delivery technology which is designed to improve the bioavailability of drugs with low water solubility. Considering the studies conducted to date, once-daily LCP-Tacro has shown improved pharmacokinetic properties, rapid achievement of therapeutic trough levels, consistent exposure, non-inferior efficacy and similar safety, with lower tacrolimus dose than other tacrolimus formulations.
