Study Description

Brief Summary:

The purpose of this FIH study is to evaluate the safety, tolerability and pharmacokinetics of ONO-2020 in healthy adult participants. This FIH study consists of five parts (Parts A-E) to study single or multiple doses of ONO-2020 in healthy participants, including elderly and Japanese participants, as well as the food effect on the PK of ONO-2020. These data will support the clinical development program and help inform dose selection in future studies.
