Evaluate the potential effect of hepatic or renal impairment on the pharmacokinetics, safety and tolerability of BAY 1841788 (ODM-201).

The study was closed after Part 1 because additional investigation in volunteers with moderate renal impairment in Part 2 was not deemed to be ethically or scientifically justified.

Inclusion Criteria:

• All subjects

  -- Male and white subjects between 45 and 79 years of age with a body mass index between 18 to 34 kg/m*2 (both inclusive).

• Patients with moderate hepatic impairment (Part 1)

  -- Patients with documented liver cirrhosis confirmed by histopathology, e.g., previous liver biopsy, laparoscopy, ultrasound, or fibroscan and with moderate hepatic impairment (defined as Child Pugh class B).

• Patients with severe renal impairment (Part 1)

  -- Patients with severe renal impairment with an estimated glomerular filtration rate 15-29 mL/min/1.73 m*2, who are not on dialysis and are not expected to start dialysis in the next 3 months (Stage 4).

• Healthy subjects

  -- Healthy as determined by the investigator or medically qualified designee based on a medical evaluation including medical history, physical examination, laboratory tests and cardiac monitoring and with estimated glomerular filtration rate >90 mL/min (according to Modified Diet of Renal Disease equation).

• Patients with moderate renal impairment (Part 2)

  -- Patients with moderate renal impairment with an estimated glomerular filtration rate 30-59 mL/min/1.73 m*2 (Stage 3).

• Patients with mild renal impairment (Part 2)

  -- Patients with mild renal impairment with an estimated glomerular filtration rate (eGFR) 60-79 mL/min/1.73 m*2 (Stage 2).

• Patients with mild hepatic impairment (Part 2)

  • Patients with documented liver cirrhosis confirmed by histopathology, e.g., previous liver biopsy, laparoscopy, ultrasound, or fibroscan.
  • Patients with mild hepatic impairment (defined as Child Pugh class A).

Exclusion Criteria:

• Severe cerebrovascular or cardiac disorders, e.g., myocardial infarction less than 6 months prior to dosing, congestive heart failure of New York Heart Association (NYHA) grade III or IV.
• Subjects with percutaneous transluminal coronary angioplasty or coronary artery bypass graft less than 6 months prior to study drug administration.
• Strong cytochrome P450 (CYP) 3A4 inhibitors or strong CYP3A4 inducers within 28 days or 5 drug half-lives (if drug half-life in patients is known), before start of study treatment.
• Known BCRP (breast cancer resistant protein) and OATP (organic anion-transporting polypeptide) substrates not specifically mentioned in the protocol within 28 days or 5 drug half-lives (if drug half-life in patients is known), before start of study treatment.
• Smoking more than 20 cigarettes daily.
