A Study in Healthy Men to Test How Different Doses of BI 1815368 Are Tolerated and How BI 1815368 is Taken up in the Body With or Without Food

A Randomised, Single-blind, Placebo-controlled Trial to Investigate Safety, Tolerability, and Pharmacokinetics of Single Rising Doses of BI 1815368 Administered as Oral Solution to Healthy Male Subjects (SRD Part), and a Randomised, Open-label, Single-dose, Three-way Cross-over Part Investigating Relative Bioavailability of BI 1815368 as Tablet Versus Oral Solution and Tablet With and Without Food in Healthy Male Subjects (BA Part)

Brief summary

Single-rising dose (SRD) part The main objectives of the SRD part of this trial are to investigate safety, tolerability and pharmacokinetics (PK) of BI 1815368 in healthy male subjects following oral administration of single rising doses. Bioavailability (BA) part The main objective of the BA part is to investigate the relative bioavailability of a tablet formulation versus oral solution and to assess the influence of food on the relative bioavailability of the tablet formulation.

Masking description

For the Single Rising Dose (SRD) part the participant is blinded. For the bioavailability (BA) part no masking is applicable.

Intervention model description

This study has 2 parts: a single rising dose (SRD) part and a bioavailability (BA) part. For the SRD part the intervention study model is sequential, while for the BA part the intervention study model is crossover.

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)), 12-lead electrocardiogram (ECG), and clinical laboratory tests * Age of 18 to 45 years (inclusive) * Body mass index (BMI) of 18.5 to 29.9 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 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 of mercury (mmHg), diastolic blood pressure outside the range of 50 to 90 mmHg, or pulse rate outside the range of 50 to 90 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
