Study Description

Brief Summary

Safety, tolerability, and pharmacokinetics of BI 474121 will be assessed in healthy Japanese male using single rising oral doses in order to provide the basis for an ongoing clinical development of BI 474121 for the treatment of cognitive impairment in patients with Alzheimer's Disease and schizophrenia.

  • born in Japan, have lived outside of Japan <10 years,

  • have parents and grandparents who are Japanese

  • Age of 20 to 45 years (inclusive) at screening visit

  • Use of adequate contraception by any of the following methods plus condom: intrauterine device, combined oral contraceptives that started at least 2 months prior to the first drug administration.

  • Vasectomized (vasectomy at least 1 year prior to enrolment)

  • Surgical sterilization (including bilateral tubal occlusion, hysterectomy or bilateral oophorectomy) of the subject's female partner.

Exclusion Criteria:
  • Any finding in the medical examination (including BP, PR or ECG) deviating from normal and assessed as clinically relevant by the investigator at screening visit

  • Repeated measurement of systolic blood pressure outside the range of 100 to 140 mmHg, diastolic blood pressure outside the range of 50 to 90 millimetre of mercury (mmHg), or pulse rate outside the range of 50 to 90 beats per minute (bpm) at screening visit

  • Any laboratory value outside the reference range that the investigator considers to be of clinical relevance at screening visit

  • Any evidence of a concomitant disease assessed as clinically relevant by the investigator

  • Gastrointestinal, hepatic, renal, respiratory, cardiovascular, metabolic, immunological or hormonal disorders

  • Diseases of the central nervous system (including but not limited to any kind of seizures or stroke), and other relevant neurological or psychiatric disorders

  • Chronic or relevant acute infections including viral hepatitis, human immunodeficiency virus (HIV) and/or syphilis.

  • History of cholecystectomy or other surgery of the gastrointestinal tract that could interfere with the pharmacokinetics of the trial medication (except appendectomy or simple hernia repair)

  • History of relevant orthostatic hypotension, fainting spells, or blackouts

  • History of relevant allergy or hypersensitivity (including allergy to the trial medication or its excipients)

  • further exclusion criteria apply
