Inclusion criteria
* Subjects with renal anemia who have been receiving ESA (intravenous treatment) within the doses approved in Japan for more than 8 weeks before the screening assessment * Mean of the subject's two most recent Hb values during the Screening Period must be ≥10.0 g/dL and ≤12.0 g/dL. * Either transferrin saturation (TSAT) ≥ 20% or serum ferritin ≥ 100 ng/mL during the screening period * Female subject must either: Be of non-childbearing potential: * post-menopausal (defined as at least 1 year without any menses) prior to Screening, or * documented surgically sterile Or, if of childbearing potential, * Agree not to try to become pregnant during the study and for 28 days after the final study drug administration * And have a negative pregnancy test at Screening * And, if heterosexually active, agree to consistently use two forms of highly effective birth control (at least one of which must be a barrier method) starting at Screening and throughout the study period and continued for 28 days after the final study drug administration. * Female subject must agree not to breastfeed starting at Screening and throughout the study period, and continued for 28 days after the final study drug administration. * Female subject must not donate ova starting at Screening and throughout the study period, and continued for 28 days after the final study drug administration. * Male subject and their female spouse/partners who are of childbearing potential must be using two forms of highly effective birth control (at least one of which must be a barrier method) starting at Screening and continue throughout the study period, and for 12 weeks after the final study drug administration * Male subject must not donate sperm starting at Screening and throughout the study period and, for 12 weeks after the final study drug administration
Exclusion criteria
* 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), or total bilirubin that is greater than the criteria, 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 consider 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
