17. Subject participated in any study or has been treated with any investigational drugs within 90 days or 5 half-lives whichever is longer, prior to screening.
18. Subject is unable to communicate, read and understand German, or any other condition which, in the Investigator’s opinion, makes the subject unsuitable for study participation.
