A Study in Healthy Men to Test if Different Formulations of BI 764198 With or Without Food Influence the Amount of BI 764198 in the Blood

Study Overview
=================
Brief Summary
-----------------
BI 764198 is intended to be used in patients hospitalized for COVID-19 at risk of respiratory complications. The present trial will investigate the relative bioavailability of BI 764198 administered as capsules versus tablets in a first part, and the relative bioavailability and food effect of four oral formulations: the newly developed tablet formulation under fed and fasted conditions as well as suspension from capsules and suspension from tablets in a second part.

Official Title
-----------------

Eligibility Criteria
-----------------
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 50 years (inclusive) at screening Body mass index (BMI) of 18.5 to 29.9 kg/m2 (inclusive) at screening Signed and dated written informed consent prior to admission to the study, in accordance with Good Clinical Practice (GCP) and local legislation Male subjects who meet any of the following criteria from first administration of trial medication until 30 days after trial completion: Use of adequate contraception by the female partners, e.g. any of the following methods plus condom: implants, injectables, combined oral or vaginal contraceptives, intrauterine device that started at least 2 months prior to first drug administration to the male subject, or barrier method (e.g. diaphragm with spermicide), or surgically sterilised (including bilateral tubal occlusion, hysterectomy or bilateral oophorectomy), or postmenopausal, defined as at least 1 year of spontaneous amenorrhea Sexually abstinent Vasectomised (vasectomy at least 1 year prior to enrolment) in combination with a barrier method (e.g. condom) Sperm donation is not allowed from first study drug administration until 30 days after trial completion. 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 mmHg, diastolic blood pressure outside the range of 50 to 90 mmHg, or pulse rate outside the range of 45 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 exclusion criteria apply.
