A Study in People With Normal Kidney Function and People With Reduced Kidney Function to Test How BI 1467335 is Processed in the Body

Inclusion criteria

• Despite of moderate renal impairment (Group 1) healthy male or female subjects according to the assessment of the investigator, 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
• Estimated glomerular filtration rate (eGFR) based on CKD-EPI formula for Group 1 between 30 and 59 mL/min/1.73m2 and for Group 2 ≥ 90 mL/min/1.73m2
• Age of 18 to 79 years (incl.)
• BMI of 18.5 to 34 kg/m2 (incl.)
• 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 (according to the CTFG Recommendations related to contraception and pregnancy testing in clinical trials, methods with a failure rate of less than 1% per year) starting from at least 30 days before the first administration of trial medication and until 30 days after trial completion, e.g.:

• Use of adequate contraception, e.g. any of the following methods plus condom: implants, injectables, combined oral or vaginal contraceptives (inhibition of ovulation)
• Hormonal intrauterine device
• Sexually abstinent (defined as refraining from heterosexual intercourse during the entire period of risk)
• A vasectomised sexual partner (provided that vasectomy was performed at least 1 year prior to enrolment and the vasectomised partner has received medical assessment of the surgical success)
• Surgically sterilised (including bilateral tubal occlusion, hysterectomy)
• Postmenopausal, defined as at least 1 year of spontaneous amenorrhea (in questionable cases a blood sample with simultaneous levels of FSH above 40 U/L and estradiol below 30 ng/L is confirmatory)

Exclusion criteria

Healthy subjects

• Any finding in the medical examination (including BP, PR or ECG) is deviating from normal and judged 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 judged as clinically relevant by the investigator
• Gastrointestinal, hepatic, renal, respiratory, cardiovascular, metabolic, immunological or hormonal disorders
• Estimated glomerular filtration rate (eGFR) calculated by CKD-EPI formula < 90 mL/min/1.73m2

Subjects with moderate renal impairment

• Subject with significant diseases other than moderate renal impairment. A significant disease is defined as a disease which in the opinion of the investigator:

• puts the subjects at risk because of participation in the study
• may influence the results of the study
• may influence the subject's ability to participate in the study
• is not in a stable condition Diabetic or hypertensive subjects can be entered in this trial if the disease is not significant according to these criteria.
• Any finding of the medical examination (including BP, PR and ECG) of clinical relevance
• Moderate and severe concurrent liver function impairment (e.g. due to hepatorenal syndrome) or biliary obstruction
• Clinically relevant laboratory abnormalities (except for renal function tests or deviation of clinical laboratory values that are related to renal impairment)
• eGFR calculated by CKD-EPI formula ≥ 60 mL/min/1.73m2 and < 30 mL/min/1.73m2

For all subjects

• Cholecystectomy and/or surgery of the gastrointestinal tract that could interfere with the pharmacokinetics of the trial medication (except appendectomy and 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 prior to administration of trial medication if that might reasonably influence the results of the trial (incl. QT/QTc interval prolongation)
• Participation in another trial where an investigational drug has been administered within 30 days prior to planned administration of trial medication or longer if required by local regulation, or within 5-half-lives of the investigational agent taken (whichever is longer), or current participation in another trial involving administration of investigational drug
• 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 20 g per day for females and 30 g per day for males)
• Drug abuse or positive drug screening
• Blood donation of more than 100 mL within 30 days prior to administration of trial medication or intended donation during the trial
• Intention to perform excessive physical activities within one week prior to administration of trial medication or during the trial
• Inability to comply with dietary regimen of trial site
• A marked baseline prolongation of QT/QTc interval (such as QTc intervals that are repeatedly greater than 450 ms in males or repeatedly greater than 470 ms in females) or any other relevant ECG finding at screening
• A history of additional risk factors for Torsades de Pointes (such as heart failure, hypokalemia, or family history of Long QT Syndrome)
• Subject is assessed as unsuitable for inclusion by the investigator, for instance, because considered not able to understand and comply with study requirements, or has a condition that would not allow safe participation in the study

Female subjects will not be allowed to participate if any of the following applies:

• Positive pregnancy test, pregnancy or plans to become pregnant within 30 days after study completion
• Lactation period

Male subjects will not be allowed to participate if any of the following applies:

• Male subjects with WOCBP partner who are unwilling to use male contraception (condom or sexual abstinence) from the first administration of trial medication until 30 days after last administration of trial medication
