Eligibility
Inclusion criteria
* Healthy males according to the following criteria, based upon a complete medical history, including the physical examination, vital signs (blood pressure (BP), pulse rate (PR)), 12-lead electrocardiogram (ECG), clinical laboratory tests * No finding deviating from normal and of clinical relevance * No evidence of a clinically relevant concomitant disease * Age ≥ 21 and Age ≤ 50 years * BMI (Body Mass Index) ≥ 18.5 and ≤ 29.9 kg/m2 * Ability to give signed and dated written informed consent prior to admission to the study in accordance with good clinical practice (GCP) and the local legislation
Exclusion criteria
