This Study in Healthy Men Tests How Itraconazole Influences the Amount of BI 1015550 in the Blood

Study Overview
=================
Brief Summary
-----------------
The primary objective of this trial is to investigate whether and to what extent co-administration of multiple doses of itraconazole affect single dose pharmacokinetics of BI1015550, i.e. to compare the relative bioavailability of 6 mg BI 1015550 when given alone (reference, treatment R) to the relative bioavailability of 6 mg of BI 1015550 given on the 4th day of a 12-day-treatment with itraconazole (test, treatment T) following oral administration in healthy male subjects.

Eligibility Criteria
-----------------
Inclusion Criteria: Healthy male subjects according to the assessment of the investigator, based on a complete medical history including a physical examination, vital signs (BP (Blood Pressure), PR (Pulse Rate)), 12-lead ECG (Electrocardiogram), and clinical laboratory tests Age of 18 to 55 years (incl.) BMI of 18.5 to 29.9 kg/m2 (incl.) Signed and dated written informed consent prior to admission to the study in accordance with GCP and local legislation Exclusion Criteria: Any finding in the medical examination (including BP (Blood Pressure), PR (Pulse Rate) or ECG (Electrocardiogram)) is deviating from normal and judged as clinically relevant by the investigator Repeated measurement of systolic blood pressure outside the range of 90 to 140 mmHg, diastolic blood pressure outside the range of 50 to 90 mmHg, or pulse rate outside the range of 45 to 90 bpm (beats per minute) Any laboratory value outside the reference range that the investigator considers to be of clinical relevance Any evidence of a concomitant disease judged as clinically relevant by the investigator Gastrointestinal, hepatic, renal, respiratory, cardiovascular, metabolic, immunological or hormonal disorders Cholecystectomy and/or surgery of the gastrointestinal tract that could interfere with the pharmacokinetics of the trial medication (except appendectomy and simple hernia repair) Diseases of the central nervous system (including but not limited to any kind of seizures or stroke), and other relevant neurological or psychiatric disorders, including but not limited to mood disorders and any history of suicidality. History of relevant orthostatic hypotension, fainting spells, or blackouts Chronic or relevant acute infections History of relevant allergy or hypersensitivity (including allergy to the trial medication or its excipients or other Azoles ) Use of drugs within 30 days prior to administration of trial medication if that might reasonably influence the results of the trial (incl. QT/QTc interval prolongation) Participation in another trial where an investigational drug has been administered within 60 days prior to planned administration of trial medication, or current participation in another trial involving administration of investigational drug Further exclusion criteria apply
