To Investigate Pharmacokinetics (Absorption, Distribution, Elimination), Safety and Tolerability of a Single Oral Dose of 75 mg Molidustat Tablet in Male and Female Subjects Requiring Hemo- or Peritoneal Dialysis Compared to Healthy Subjects

The study investigates the pharmacokinetics (absorption, distribution, elimination) of molidustat after intake of a single 75 mg tablet in subjects with renal impairment requiring hemo- or peritoneal dialysis compared to age-and gender-matched healthy subjects. In addition, the effect of molidustat on the hormone erythropoietin will be evaluated as well as the safety and tolerability of molidustat.
