A Study of Molidustat for Treatment of Renal Anemia in Peritoneal Dialysis Subjects

The purpose of this study is to evaluate the efficacy and safety of molidustat in peritoneal dialysis subjects with renal anemia


Eligibility Criteria:
Inclusion Criteria:

* Subject with end-stage kidney disease (ESKD) on peritoneal dialysis prior to assignment and not expected to start maintenance dialysis (e.g., hemodialysis, hemodiafiltration) other than peritoneal dialysis during the study period
* Body weight \> 40 and ≤ 160 kg at screening
* Male or female subject ≥ 20 years of age at screening
* At least one kidney
* Subjects who meet one of the 1 or 2 following criteria

  * Subjects untreated with ESA at assignment: Mean of the last 2 Hb level (central laboratory measurement) during the screening period must be ≥ 8.0 and \< 11.0 g/dL (2 measurements must be taken ≥ 2 days apart and the difference between the 2 measurements must be \< 1.2 g/dL) with the last screening Hb measurement within 14 days prior to study drug assignment
  * Subjects pre treated with ESA at assignment: Mean of the last 2 Hb level (central laboratory measurement) during the screening period must be ≥ 10.0 and \< 13.0 g/dL (2 measurements must be taken ≥ 2 days apart and the difference between the 2 measurements must be \< 1.2 g/dL) with the last screening Hb measurement within 14 days prior to study drug assignment
* Subjects who meet one of the 1 or 2 following criteria

  * Subjects untreated with ESA at assignment: Subject with ESKD on peritoneal dialysis for at least 2 weeks prior to assignment. AND. Subject not received ESA for 8 weeks prior to assignment. OR. In case of the patient washed out from ESAs, when mean of the last 2 Hb level (at least 2 central laboratory measurements must be taken ≥ 2 days apart) has decrease to ≥ 0.5g/dL from the Hb level (central laboratory measurement) after the last ESA administration, AND the interval from the last ESA administration to the study drug assignment should be over 2 week for epoetin-alpha/beta, 4 weeks for darbepoetin alpha or epoetin beta pegol
  * Subjects pre treated with ESA at assignment:

    * Subject with ESKD on peritoneal dialysis for at least 12 weeks prior to assignment
    * Subject treated with ESA by IV or SC within 8 weeks prior to assignment
    * Treated with 2 or 4 weekly dose of darbepoetin alfa, 4 weekly dose of epoetin beta pegol, OR 3 times per week, twice per week, weekly or bi-weekly dose of epoetin alfa/beta, and having had no more than one dose change within 8 weeks prior to assignment

Exclusion Criteria:

* New York Heart Association (NYHA) Class III or IV congestive heart failure
* History of cardio- (cerebro-) vascular events (e.g., unstable angina, myocardial infarction, stroke, pulmonary thromboembolism, and acute limb ischemia) within 6 months prior to randomization
* Sustained and poorly controlled arterial hypertension (defined as systolic BP≥ 180mmHg or diastolic BP ≥ 110mmHg) or hypotension (defined as systolic BP \< 90mmHg) at randomization
* Proliferative choroidal or retinal disease, such as neovascular age-related macular degeneration or proliferative diabetic retinopathy requiring invasive treatment (e.g., intraocular injections or laser photocoagulation)
