Abstract
This was an open-label, randomized, single-dose, 2-period, crossover clinical trial with an adaptive design to evaluate the bioequivalence and comparative pharmacokinetics of generic glecaprevir/pibrentasvir versus the brand name product in healthy White male and female volunteers under fed conditions. Safety profiles were also assessed. A total of 56 healthy adult volunteers were enrolled and randomly assigned in a 1:1 ratio to receive a single dose of either the generic or reference formulation. After a 7-day washout period, subjects received the alternate product. Blood samples were collected at pre-specified time points up to 48hours post-dosing. Plasma concentrations of glecaprevir and pibrentasvir were determined using a validated high-performance liquid chromatography-tandem mass spectrometry method. The geometric mean ratios of the test to the reference formulation for maximum plasma concentration (Cmax) and area under the concentration-time curve from drug administration to the last measurable concentration (AUC0-t) fell within the predefined bioequivalence range of 80%-125%. Both formulations demonstrated comparable pharmacokinetic profiles for glecaprevir and pibrentasvir, and can be considered bioequivalent. No adverse events were reported, and both formulations were well tolerated by all participants.
