The goal of this study is to assess the bioequivalence (BE) between the liquid formulation and the new solid formulation of ABX-002 under fasting conditions and to evaluate the effect of food on the pharmacokinetics (PK) of the new solid formulation of ABX-002.This study design is consistent with FDA guidelines for the assessment of BE. This was an open label, randomized, single dose, three-way crossover BE and food-effect study. Therefore, the total number of participants in this study was 18.
