Summary
This early-stage trial tested the safety and how the body handles single doses of an experimental drug called BI 706321 in 73 healthy men. The study had two parts: one to check safety and drug levels after increasing doses, and another to compare different pill forms and the effect of food. Since this is a Phase 1 study in healthy people, it does not aim to treat any disease.

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 (BP, PR, oral body temperature), 12-lead ECG, and clinical laboratory tests * Age of 18 to 45 years (inclusive) in Part I and of 18 to 55 years (inclusive) in Part II * BMI of 18.5 to 29.9 kg/m2 (inclusive) * 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 Blood Pressure (BP), (PR), oral body temperature 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 50 to 90 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 * Chronic or relevant acute infections * History of relevant allergy or hypersensitivity (including allergy to the trial medication or its excipients) * Use of drugs within 30 days of planned administration of trial medication that might reasonably influence the results of the trial (including drugs that cause QT/QTc interval prolongation) * Intake of an investigational drug in another clinical trial within 60 days of planned administration of investigational drug in the current trial, or concurrent participation in another clinical trial in which investigational drug is administered * Smoker (more than 10 cigarettes or 3 cigars or 3 pipes per day) * Inability to refrain from smoking on specified trial days * Alcohol abuse (consumption of more than 24 g per day) * Drug abuse or positive drug screening * Blood donation of more than 100 mL within 30 days of planned administration of trial medication or intended blood donation during the trial * Intention to perform excessive physical activities within one week prior to the administration of trial medication or during the trial * Inability to comply with the dietary regimen of the trial site * A marked baseline prolongation of QT/QTc interval (such as QTc intervals that are repeatedly greater than 450 ms) or any other relevant ECG finding at screening * A history of additional risk factors for Torsade de Pointes (such as heart failure, hypokalaemia, or family history of Long QT Syndrome) * Subject is assessed as unsuitable for inclusion by the investigator, for instance, because the subject is not considered able to understand and comply with study requirements, or has a condition that would not allow safe participation in the study * Male subjects with WOCBP partner who are unwilling to use male contraception (condom or sexual abstinence) from time point of administration of trial medication until 30 days thereafter. Sperm donation is not allowed from the time point of drug administration until 30 days thereafter. * ALT (alanine transaminase), AST (aspartate transaminase), or creatinine exceed upper limit of normal range at screening, confirmed by a repeat test * During COVID-19 pandemic: laboratory test indicative of an ongoing SARS-CoV-2 infection
