This is a Phase 1, two-part, randomized, double blind, placebo controlled, single ascending dose (Part 1) and multiple ascending dose (Part 2) study to evaluate the safety, tolerability, pharmacokinetics (PK) of STI-1558 administered orally to healthy volunteers. Part 1 of the study will also incorporate a single-cohort arm to investigate the effect of food on the PK of STI-1558. Dietary status of administration in part 2 (fasted or fed) will be determined by the PK data from Part 1. Part 2 may run in parallel with Part 1, providing that the total daily dose to be administered does not exceed a dose already shown to be safe and well-tolerated in Part 1.
