Anemia, Renal Insufficiency, Chronic
About this trial
This is an interventional treatment trial for Anemia focused on measuring Anemia on CKD
Eligibility Criteria
Inclusion Criteria:
- Male or female subjects ≥ 18 years of age with anemia of chronic kidney disease (CKD) at screening
- Estimated glomerular filtration rate (eGFR) of < 60 mL/min/1.73 m2 (Modification of Diet in Renal Disease or the formula according to Matsuo, et al.)
- Not on dialysis and not expected to begin dialysis during the treatment period of the study (at least 16 weeks from randomization)
- Treated with darbepoetin via intravenous (IV) or subcutaneous (SC) route with a weekly, bi-weekly, or monthly dose, having had no more than one dose change within 8 weeks prior to randomization
- At least one kidney
- Mean screening hemoglobin (Hb) concentration of 10.0 to 12.0 g/dL
- Men who agree to use adequate contraception when sexually active or women without childbearing potential
Exclusion Criteria:
- Subjects with significant acute or chronic bleeding, such as overt gastrointestinal bleeding
- Active hemolysis or diagnosis of hemolytic syndrome
- History of myelodysplastic syndrome, multiple myeloma, marrow fibrosis, or pure red-cell aplasia (PRCA)
- History of hemosiderosis or hemochromatosis
- Hereditary hemoglobinopathies (such as sickle cell disease and thalassemia major)
- Aplastic anemia
- Chronic lymphoproliferative diseases
- Proliferative choroidal or retinal disease, such as neovascular age-related macular degeneration or proliferative diabetic retinopathy that is likely to require invasive treatment (intraocular injections or laser photocoagulation) during the study
- Chronic inflammatory disease that could impact erythropoiesis (e.g., systemic lupus erythematosis, rheumatoid arthritis, celiac disease) even if it is currently in remission
- Known hypersensitivity to the study drugs (active substances or excipients of the preparations)
- Uncontrolled and symptomatic hyperparathyroidism
- Uncontrolled active infection
- Previous or concurrent cancer except cervical carcinoma in situ, treated basal cell carcinoma, superficial bladder tumors (Ta, Tis, and T1) or any cancer curatively treated > 3 years prior to randomization
- Any allograft (including renal allograft) in place and on immunosuppressive therapy or a scheduled kidney transplant within the next 16 weeks (being on a waiting list does not exclude the subject)

Darbepoetin alfa
Fixed starting dose of 25 mg of BAY85-3934 oral tablet (once daily dose) titrated at the scheduled dose control visits. Titration occuring every 4-weeks will be based on the subject's hemoglobin (Hb) response and tolerability of the prior dose. Total treatment time is 16 weeks. Planned doses include 15, 25, 50, 75, 100, and 150 mg once daily.
Fixed starting dose of 50 mg of BAY85-3934 oral tablet (once daily dose) titrated at the scheduled dose control visits. Titration occuring every 4-weeks will be based on the subject's Hb response and tolerability of the prior dose. Total treatment time is 16 weeks. Planned doses include 15, 25, 50, 75, 100, and 150 mg once daily.
Fixed starting doses of 75 mg of BAY85-3934 oral tablet (once daily dose) titrated at the scheduled dose control visits. Titration occuring every 4-weeks will be based on the subject's Hb response and tolerability of the prior dose. Total treatment time is 16 weeks. Planned doses include 15, 25, 50, 75, 100, and 150 mg once daily.
Darbepoetin (intravenous or subcutaneous) will be administered according to the local label and titrated at the scheduled dose control visits. Titration will be based on the subject's Hb response and tolerability of the prior dose.
