SAD, MAD and Food Effect Evaluation of Safety, Tolerability, and PK of AQ280 in Healthy Subjects

Study Overview
=================
Brief Summary
-----------------
The principal aim of this study is to obtain safety and tolerability data when AQ280 is administered orally as single and multiple doses to healthy subjects. This information, together with the pharmacokinetic (PK) data, will help establish the doses and dosing regimen suitable for future studies in patients.
