This Study Tests BI 1467335 in Healthy Japanese and Caucasian Men. The Study Tests How Different Doses of BI 1467335 Are Taken up in the Body and How Well They Are Tolerated

Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Multiple Rising Oral Doses of BI 1467335 in Healthy Japanese Male Volunteers With Multiple Oral Doses at the Highest Dose in Caucasian for Comparison (Randomised, Double-blind, Placebo-controlled Trial)

The primary objective of the current study is to investigate the safety and tolerability of BI 1467335 in healthy Japanese male subjects following oral administration of multiple rising doses The Caucasian group will receive higher dose only.

A secondary objective is the exploration of the pharmacokinetics and pharmacodynamics of BI 1467335 in healthy Japanese and Caucasian male subjects.
