A Study of Intermittent Oral Dosing of ASP1517 in Non-Dialysis Chronic Kidney Disease Patients With Anemia
- Registration Number
- NCT02988973
- Lead Sponsor
- Astellas Pharma Inc
- Brief Summary
The objective of this study is to evaluate the efficacy and safety of ASP1517 when converted from recombinant human erythropoietin (rHuEPO) or darbepoetin alfa (DA), compared to DA in the treatment of anemia in non-dialysis chronic kidney disease patients. Another uncontrolled cohort will be included to evaluate the efficacy and safety of ASP1517 in patients converted from epoetin beta pegol (CERA). This study will also assess the safety/efficacy of long term treatment of ASP1517 (52 weeks).
- Detailed Description
This study consists of the following three cohorts. Cohort 1; subjects converted from rHuEPO or DA to ASP1517, Cohort 2; subjects converted from rHuEPO or DA to DA, Cohort 3; subjects converted from epoetin beta pegol (CERA) to ASP1517. In Cohort 1 and 3, ASP1517 will be administered orally for 52 weeks. In Cohort 2, DA will be administered subcutaneously for 24 weeks.

Group Intervention Description rHuEPO or DA to ASP1517 roxadustat Participants will receive roxadustat according to the prior randomization treatment, with starting doses of 70mg thrice weekly (TIW) to participants on \<4500 IU/week of rHuEPO or \<20 microgram (μg)/week of darbepoetin alfa (DA) and 100mg TIW to participants on ≥4500 IU/week rHuEPO or ≥ 20 μg/week DA. Participants roxadustat dosage will be adjusted every 4 weeks to maintain Hb level within the target range 10.0 to 12.0 g/dL. Dose adjustment steps will be as follows: 20, 40, 50, 70, 100, 150, 200, 250, 300 mg. rHuEPO or DA to DA DA Participants will receive DA according to the prior randomization treatment, with starting doses of 15 μg/2weeks to participants on ≤ 1500 IU/week of rHuEPO or \<11.25 microgram (μg)/week of DA, 30μg/2weeks to participants on \>1500 to \<6000 IU/week of rHuEPO or ≥ 11.25 to \< 22.5 μg/week of DA, 60μg/2weeks to participants on ≥ 6000 IU/week of rHuEPO or ≥ 22.5 to \< 37.5 μg/week of DA, 90μg/2weeks to participants on ≥ 37.5 to \< 52.5 μg/week of DA, 120μg/2weeks to participants on ≥ 52.5 to \< 75 μg/week of DA, 180μg/2weeks to participants on ≥ 75 μg/week of DA.
