Brief summary: * To investigate the influence of different doses of BI 1026706 on the primary endpoint (PtP-amplitude LEP in UV skin) compared to placebo.
* The comparison of both doses of BI 1026706 to celecoxib in the UVB treatment.
* Comparison of both doses of BI 1026706 to placebo and pregabalin in the capsaicin treatment
* Exploration of the pharmacokinetics of BI 1026706
* Exploration of safety and tolerability of BI 1026706


Eligibility criteria: Inclusion criteria:

1. Healthy males according to the investigator's assessment, as based on the following criteria: a complete medical history including a physical examination, vital signs (Blood Pressure, Pulse Rate), 12-lead electrocardiogram, and clinical laboratory

2. Repeated measurement of systolic blood pressure greater than 140 mm Hg or diastolic blood pressure greater than 90 mm Hg
3. Any laboratory value outside the reference range that the investigator considers to be of clinical relevance
4. Any evidence of a concomitant disease judged clinically relevant by the investigator
5. Gastrointestinal, hepatic, renal, respiratory, cardiovascular, metabolic, immunological or hormonal disorders
6. Surgery of the gastrointestinal tract that could interfere with kinetics of the study drug(s)
7. Diseases of the central nervous system (such as epilepsy), other neurological disorders or psychiatric disorders
