Exclusion criteria
* Subjects who had trouble with continuing peritoneal dialysis due to peritonitis, development of catheter trouble (e.g. tunnel infection) within 4 weeks before the screening assessment * Concurrent retinal neovascular lesion requiring treatment and macular edema requiring treatment * Concurrent autoimmune disease with inflammation that could impact erythropoiesis * History of gastric/intestinal resection considered influential on the absorption of drugs in the gastrointestinal tract (excluding resection of gastric or colon polyps) or concurrent gastro-paresis * Uncontrolled hypertension * Concurrent congestive heart failure (NYHA Class III or higher) * History of hospitalization for treatment of stroke, myocardial infarction, or pulmonary embolism within 12 weeks before the screening assessment * Positive for hepatitis B surface antigen (HBsAg) or anti-hepatitis C virus (HCV) antibody at the screening assessment, or positive for human immunodeficiency virus (HIV) in a past test * Concurrent other form of anemia than renal anemia * Having received treatment with protein anabolic hormone, testosterone enanthate, or mepitiostane within 6 weeks before the screening assessment * Aspartate Aminotransferase (AST), Alanine Aminotransferase (ALT), total bilirubin, or Alkaline Phosphatase (ALP) that is greater than the criteria below, or previous or concurrent another serious liver disease at screening assessment * Previous or current malignant tumor (no recurrence for at least 5 years is eligible.) * Having undergone blood transfusion and/or a surgical procedure considered to promote anemia (excluding shunt reconstruction surgery for access to the blood) within 4 weeks before the screening assessment * Having undergone a kidney transplantation * Having a previous history of treatment with ASP1517 * History of serious drug allergy including anaphylactic shock * Participation in another clinical study or post-marketing clinical study (including that of a medical device) within 12 weeks before informed consent acquisition
