We set the bar by recruiting more than 2,000 volunteers to phase I trials targeting elderly people, aged 65 years or older.

So that volunteers can apply to participate in clinical trials with confidence, we have a reliable system in place for managing personal information such as the acquirement of Privacy Mark.
