A Study to Learn How BAY94-8862 Moves Into, Through and Out of the Body, How Safe it is and How it Affects the Body in Adult Participants With Reduced Kidney Function and in Healthy Participants With Similar Age, Weight and Gender Distribution

Inclusion criteria

• The informed consent must be signed before any study specific tests or procedures are done;
• Male participants and female participants without childbearing potential (postmenopausal women with 12 month of spontaneous amenorrhea or with 6 month of spontaneous amenorrhea and serum follicle-stimulating hormone (FSH) levels >30 mIU/mL; women with 6 weeks post bilateral ovarectomy, women with bilateral tubal ligation, and women with hysterectomy);
• Age: 18 to 79 years at the first screening examination;
• Race: White;
• Body mass index (BMI): ≥ 18 and ≤ 34 kg / m2;

Participants with renal impairment

• Creatinine clearance (CLCR) ≤ 80 mL/min determined from a 24 hour urine collection interval 2 - 14 days prior to dosing;
• Stable renal disease, ie a serum creatinine value determined at least 3-6 months before the pre-study visit should not vary by more than 20% from the serum creatinine value determined at the pre-study visit;

Healthy participants

• Mean age and body weight in Group 1 (control group, healthy participants) and Groups 2 - 4 should not vary by more than +/- 10 years and +/- 10 kg, respectively.

Exclusion criteria

• Participation in another clinical trial during the preceding 3 months for multiple dose studies and 1 month for single-dose studies; (final examination from previous study to first treatment of new study);
• Exclusion periods from other studies or simultaneous participation in other clinical studies;
• Donation of more than 100 mL of blood within 4 weeks before the first study drug administration or more than 500 mL in the preceding 3 months;
• Regular use of following medication during or within the 1 - 2 weeks preceding the study:

• concomitant administration of other Aldosterone-antagonists (eg. eplerenone or spironolactone), potassium-sparing diuretics, potassium supplements, nonsteroidal anti-inflammatory drugs like ASS (secondary prevention with a dose of 100 mg daily is allowed), indomethacin or ibuprofen
• concomitant use of cytochrome P450 isoenzyme 3A4 (CYP3A4) inducers (eg St. John´s wort, rifampicin, carbamazepin, phenytoin, phenobarbital, bosentan)
• concomitant use of weak to moderate CYP3A4 inhibitors (eg erythromycin, quinupristin/dalfopristin, saquinavir, fluconazole, amiodarone, diltiazem, fluvoxamine, verapamil, valproic acid, fluoxetine, grapefruit juice)
• strong inhibitors of CYP3A4 (eg human immunodeficiency virus (HIV) protease inhibitors like indinavir, nelfinavir, ritonavir, atazanavir, lopinavir, amprenavir and saquinavir; macrolide/ketolide antibiotics like clarithromycin, telithromycin; antimycotic agents like itraconazole and ketoconazole [topical formulations will be allowed]; nefazodone)
• moderate and strong inhibitors of cytochrome P450 isoenzyme 2C8 (CYP2C8) (eg gemfibrozil, montelukast, trimethoprim, glitazones)
• Women of childbearing potential, pregnant or lactating women;
• Positive results for hepatitis B virus surface antigen (HBsAg), hepatitis C virus antibodies (anti-HCV), human immune deficiency virus antibodies (anti-HIV 1+2);
• Serum potassium level ≥ 5.5 mmol/L;
• Serum sodium level ≤ 130 mmol/L;

For participants with renal impairment

• Acute renal failure;
• Acute nephritis;
• Any organ transplant;
• Failure of any other major organ system other than the kidney;
• Diastolic blood pressure (DBP) > 100 mmHg and/or systolic blood pressure (SBP) > 180 mmHg (at the pre-study examination; readings taken at the end of the dosing interval of antihypertensive medication, if any);
• Heart rate below 45 or above 110 BPM at screening visit;
• Hemoglobin < 8 g/dL;
• Serum albumin < 30 g/L;
• Severe cerebrovascular or cardiac disorders, eg myocardial infarction less than 6 months prior to dosing, congestive heart failure of New York Heart Association (NYHA) grade III or IV, decompensated heart failure, severe arrhythmia requiring antiarrhythmic treatment;

For healthy participants

• A history of relevant diseases of vital organs, of the central nervous system or other organs;
• Systolic blood pressure below 100 mmHg or above 145 mmHg;
• Diastolic blood pressure above 95 mmHg;
• Heart rate below 45 or above 95 BPM at screening visit;
• Clinically relevant deviations of the screened laboratory parameters in clinical chemistry, hematology, or urinalysis from reference range;
• Relevant deviation from the normal range in the clinical examination as judged by the investigator.
