Eligibility Criteria

Inclusion Criteria

For preliminary enrollment

• Patients with stable chronic kidney disease who received hemodialysis 3 times a week for at least 12 weeks (84 days) prior to the day of preliminary enrollment
• Patients who did not have dialysis conditions altered (dialysate calcium concentration, dialyser, and dry weight) within 10 days prior to the day of preliminary enrollment
• Patients who did not have the following dosage or administration altered at least 28 days prior to the day of preliminary enrollment: phosphate binders, or drugs/food with phosphate binding action (including newly started treatment)
• If receiving vitamin D or calcitonin agent, patients who did not have dosage and administration altered (including newly started treatment) for at least 28 days prior to the day of preliminary enrollment.
• Patients who did not use cinacalcet hydrochloride for at least 28 days prior to the day of preliminary enrollment

For practical enrollment

• Patients whose pre-dialysis serum phosphorus level after the maximum dialysis interval at Week 1 of the washout period was ≥8.0 mg/dL and <10.0 mg/dL or that at Week 2 was ≥6.0 mg/dL and <10.0 mg/dL
• Patients who continued to receive hemodialysis 3 times a week after the day of preliminary enrollment
• Patients who did not have dialysis conditions altered (dialysate calcium concentration and dialyser) after the day of preliminary enrollment
• Patients who did not receive phosphate binders, or drugs/food with phosphate binding action during the washout period
• If receiving vitamin D or calcitonin agent (including start of new treatment) after the day of preliminary enrollment, patients who did not have dosage and administration altered for at least 28 days prior to the day of preliminary enrollment
• Patients who did not use cinacalcet hydrochloride after the day of preliminary enrollment

Exclusion Criteria

For preliminary enrollment

• Patients with a history of gastrectomy or enterectomy (except for appendectomy) or with a complication of dysphagia, ileus, or hemorrhagic gastrointestinal lesions
• Patients with severe persistent constipation or diarrhoea
• Patients who underwent parathyroid intervention (parathyroidectomy [PTx], percutaneous ethanol injection therapy [PEIT], etc.) within 1 year prior to the day of preliminary enrollment
• Patients who are fasted or are on extreme dietary restrictions
• Patients with uncontrollable hypertension (all the last 3 measurement values of pre-dialysis systolic/diastolic blood pressure before the day of preliminary enrollment are ≥180 mmHg and ≥120 mmHg, respectively)
• Patients with severe heart disease (congestive heart failure [NYHA cardiac function classification Class III or severer], a history of extensive old myocardial infarction, etc.) or patients who were hospitalized for the treatment of cerebrovascular disease or heart disease within 12 weeks (84 days) prior to the day of preliminary enrollment
• Patients with a complication of serious hepatic disease (acute and active chronic hepatitis, hepatic cirrhosis, etc.)
• Patients with a history of serious drug hypersensitivity, such as anaphylactic shock
• Patients with a history or complication of malignant tumor (considered eligible if recurrence has not been observed for at least 5 years)
• Patients who are pregnant, nursing, suspected to be pregnant, or wish to become pregnant during the study period
• Patients who have previously received ASP1585
• Patients who participated in another clinical study or a post-marketing clinical study (including that of a medical device) within 12 weeks (84 days) prior to informed consent

For practical enrollment

• Patients whose pre-dialysis serum phosphorus level after the maximum dialysis interval at Week 1 or 2 of the washout period was ≥10 mg/dL
• Patients who underwent gastrectomy or enterectomy, or had dysphagia, ileus, or hemorrhagic gastrointestinal lesions after the day of preliminary enrollment
• Patents who had severe persistent constipation or diarrhoea after the day of preliminary enrollment
• Patients who underwent parathyroid intervention (parathyroidectomy [PTx], percutaneous ethanol injection therapy [PEIT], etc.) after the day of preliminary enrollment
• Patients who were fasted or on extreme dietary restriction after the day of preliminary enrollment
• Patients with uncontrollable hypertension (more than two thirds of pre-dialysis systolic/diastolic blood pressure values were ≥180 mmHg and ≥120 mmHg, respectively, after the day of preliminary enrollment)
• Patients with severe heart disease (congestive heart failure [NYHA cardiac function classification Class III or severer], etc.) or patients who were hospitalized for the treatment of cerebrovascular disease or heart disease after the day of preliminary enrollment
