Brief summary: This study will assess the efficacy and safety of subcutaneous or intravenous R744 in renal anemia patients on Peritoneal Dialysis.


Eligibility criteria: Inclusion Criteria:

* Patients who have been receiving peritoneal dialysis for at least 12 weeks before registration
* Patients aged ≥ 20 years at the time of obtaining consent
* Patients who have been receiving a rHuEPO preparation at least once a month for at least 8 weeks before registration
* Patients whose mean value of Hb concentrations determined within 8 weeks before registration has been between 10.0 g/dL and \<12.0 g/dL
* Patients whose transferrin saturation has been ≥ 20 % or ferritin has been ≥ 100ng/mL at any one time point within 8 weeks before registration

Exclusion Criteria:

* Patients with hardly controllable hypertension (patients whose diastolic blood pressure has been ≥ 100 mmHg on more than 1/3 of the determining occasions within 12 weeks before registration
* Patients with congestive cardiac failure (≥ Class III in NYHA cardiac function classification)
* Female patients who are pregnant, lactating, possibly pregnant or not willing to take a contraceptive measure in the period from the day of starting the treatment with the study drug to 90 days after the day of the last dose of the study drug
* Patients with complication of myocardial infarction, pulmonary infarction or cerebral infarction (excluding asymptomatic cerebral infarction)
* Patients confirmed to have serious allergy or serious drug allergy (shock, anaphylactoid symptom)
* Patients hypersensitive to a rHuEPO preparation
* Patients with malignant tumor (including hemic malignant tumor), severe infection, systemic hemic disease (osteomyelodysplasia syndrome, hemoglobinopathy, etc.), hemolytic anemia or apparent hemorrhagic lesion such as digestive tract hemorrhage
* Patients who have had an onset of peritonitis within 4 weeks before registration
* Patients who have received an anabolic hormone preparation, testosterone enanthate or mepitiostane within 12 weeks before registration
* Patients who have received another investigational drug within 12 weeks before registration
* Patients who have received R744 before registration
* Patients whose AST(GOT) value ≥ 100 IU/L or ALT(GPT) value ≥ 100 IU/L before registration
* Patients who have received erythrocyte transfusion within 16 weeks before registration
* Patients for whom a surgical operation accompanied by marked bleeding is planned during the study period
* In addition, patients who are judged as ineligible to participate in this study by the investigator or sub-investigator
