A First in Human Study to Assess the Safety, Tolerability and Pharmacokinetics of ONO-2808-01 in Healthy Participants

A Randomised, Double Blind, Placebo Controlled, Single Centre, Three-Part Study to Assess the Safety, Tolerability and Pharmacokinetics of Single and Multiple Oral Doses of ONO-2808 in Healthy Subjects.

This is a first in human study to determine the safety, tolerability and pharmacokinetics of ONO-2808 in healthy adult participants. The study will be conducted in 3 parts: Part A, a single-ascending dose part with an assessment of the potential food effects in non-Japanese adult participants; Part B, a single dose part to assess the effect of age in non-Japanese elderly participants; and Part C, a multiple-ascending dose part with ONO-2808 administered to healthy subjects.
