Venous Thromboembolism
Conditions
Brief summary
This is a first in human study to determine the safety, tolerability, pharmacokinetics and pharmacodynamics of ONO-7684 in healthy adult volunteers. This study will be conducted in 2 parts: Part A is a single-ascending dose and Part B is a multiple-ascending dose.
Detailed description
This study aims to obtain safety, tolerability, pharmacokinetic and pharmacodynamic data when ONO-7684 is administered orally as single doses and as multiple doses to healthy subjects. The study will consist of 2 parts: A single ascending dose (SAD) phase (Part A); a multiple ascending dose (MAD) phase (Part B). One cohort of Part A will receive ONO-7684 under both fasted and fed conditions to investigate the effect of food.
