A Study in Healthy Men and Women to Test Whether BI 1358894 Influences the Amount of Bupropion in the Blood

Phase 1

Completed

Brief Summary: The main objective of this trial is to investigate the relative bioavailability of a single dose of bupropion when given alone (Reference) compared with co-administration (Test) with BI 1358894 in healthy volunteers.

Recruitment & Eligibility

Inclusion Criteria

Healthy male or female 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 55 years (inclusive)
Body mass index (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 Good Clinical Practice (GCP) and local legislation
Male subjects, or female subjects who meet any of the following criteria from at least 30 days before the first administration of trial medication until 30 days after trial completion:
- Sexually abstinent
- Use of adequate contraception, e.g. any of the following methods plus condom: implants, injectables, intrauterine device
- A vasectomised sexual partner (vasectomy at least 1 year prior to enrolment)
- Surgically sterilised (including hysterectomy)
- Postmenopausal, defined as at least 1 year of spontaneous amenorrhea (in questionable cases a blood sample with levels of follicle stimulating hormone (FSH) above 40 U/L and estradiol below 30 ng/L is confirmatory)

Exclusion Criteria

Any finding in the medical examination (including safety laboratory, 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
