The primary objective of this trial was to investigate safety and tolerability of multiple doses of BI 409306 in healthy young and elderly volunteers.

The secondary objective was to explore the pharmacokinetics and pharmacodynamics of multiple doses of BI 409306 in healthy young and elderly volunteers


Eligibility Criteria:
