A Study to Test How Different Doses of Nerandomilast (BI 1015550) Are Taken up in the Body of Healthy Japanese Men

Pharmacokinetics of R-BI 1015550 After Single Oral Doses of BI 1015550 in Japanese Healthy Male Subjects (Open-label, Non-randomised, and Parallel Group Design)

The main objectives of this trial are to investigate pharmacokinetics (PK) of R-BI 1015550 in Japanese healthy male subjects following oral administration of two different single BI 1015550 doses.

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: Adult
• Accepts Healthy Volunteers: Yes

Description

Inclusion Criteria:

• Healthy male subjects according to the assessment of the investigator, as based on a complete medical history including a physical examination, vital signs (blood pressure (BP), pulse rate (PR), Respiratory rate (RR)), 12-lead Electrocardiogram (ECG), and clinical laboratory tests
• Age of 18 to 45 years (inclusive)
• Body mass index (BMI) of 18.5 to 25 kg/m2 (inclusive)
• Signed and dated written informed consent in accordance with International Council for Harmonisation-Good Clinical Practice (ICH-GCP) and local legislation prior to admission to the trial

Exclusion Criteria:

• Any finding in the medical examination (including BP, PR, RR or ECG) deviating from normal and assessed as clinically relevant by the investigator
• Repeated measurement of systolic blood pressure outside the range of 90 to 140 millimetre(s) of mercury (mmHg), diastolic blood pressure outside the range of 40 to 90 mmHg, or PR outside the range of 40 to 99 beats per minute (bpm)
• Any laboratory value outside the reference range that the investigator considers to be of clinical relevance
• Any evidence of a concomitant disease assessed as clinically relevant by the investigator
• Gastrointestinal, hepatic, renal, respiratory, cardiovascular, metabolic, immunological or hormonal disorders
• Cholecystectomy or other surgery of the gastrointestinal tract that could interfere with the pharmacokinetics of the trial medication (except appendectomy or 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
• History of relevant orthostatic hypotension, fainting spells, or blackouts Further exclusion criteria apply.

IPD Plan Description

Clinical studies sponsored by Boehringer Ingelheim, phases I to IV, interventional and non-interventional, are in scope for sharing of the raw clinical study data and clinical study documents. Exceptions might apply, e.g. studies in products where Boehringer Ingelheim is not the license holder; studies regarding pharmaceutical formulations and associated analytical methods, and studies pertinent to pharmacokinetics using human biomaterials; studies conducted in a single center or targeting rare diseases (in case of low number of patients and therefore limitations with anonymization).
