This is a phase I, randomised, double-blind , placebo controlled study to investigate the safety, tolerability, and PK of AX-158 in healthy male participants following single (Part A) and multiple (Part C) ascending doses including food effect (Part B).The study will be conducted in three parts (Part A, Part B and Part C). Part A will enrol 8 participants per cohort randomised (3 :1) to receive AX-158 (6 participants) or placebo (2 participants). Part A will follow a single ascending dose (SAD) design with all participants receiving one dose of AX-158 (or placebo) in the fasted state. Part B (Food Effect) will be conducted in 8 participants in a cross-over manner; each participant will receive AX-158 in the fed and fasted state. Part C will enrol 8 participants per cohort randomised to (3 :1) to receive AX-158 (6 participants) or placebo (2 participants). Part C will follow a multiple ascending dose (MAD) design with participants receiving AX-158 (or placebo) once daily for 10 consecutive days, in a fed or fasted state (depending on the outcome of the Part B (Food Effect).
This is a Phase I Healthy volunteer study with the primary objective to evaluate the safety and pharmacokinetics profile of AX-158. The first part will evaluate single ascending dose administrations. A substudy will be performed as well to evaluate possible impact of food on drug exposure if administered under fasted or fed state. The second part will evaluate multiple ascending dose over 10 days of dosing in fed or fast state depending on the results of the substudy food effect on AX-158.
