Study summary

Evaluate efficacy and safety of 16 weeks of titrated dose treatment with BAY85-3934 versus epoetin alfa/beta as measured by hemoglobin (Hb) levels. Fixed starting doses of 25, 50,75 and 150 mg of BAY85-3934 titrated at the scheduled dose control visits. Titration will be based on the subject's Hb response and tolerability of the prior dose. Planned doses include 15, 25, 50, 75, 100,150 and 200 mg/day

Exclusion criteria

  • Subjects with significant acute or chronic bleeding, such as overt gastrointestinal bleeding
  • Hereditary hemoglobinopathies (including, but not limited to, sickle cell disease, beta thalassemia, and thalassemia major) which may be the primary cause of anemia
  • Chronic lymphoproliferative diseases
  • 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)
  • Chronic inflammatory disease that could impact erythropoiesis (e.g., systemic lupus erythematosis, rheumatoid arthritis, celiac disease)
  • Subjects treated with immuno- or myelosuppressive therapy within 8 weeks prior to randomization: e.g., everolimus, sirolimus, rituximab, azathioprine, mycophenolate mofetil, mycophenolic acid, cyclosporine,methotrexate, and tacrolimus, chemotherapeutic agents and other anticancer agents, and systemic steroids (except inhaled steroids) for 7 days
  • RBC-containing transfusion within 8 weeks before randomization
  • History of cardio- (cerebro-) vascular events (e.g., unstable angina, myocardial infarction, stroke, transient ischemic attack, deep vein thrombosis, pulmonary embolism) within the last 6 months from the initial screening visit
  • Sustained, poorly controlled arterial hypertension or hypotension at screening, defined as a mean BP ≥ 180/110 mmHg or systolic BP \< 95 mmHg, respectively
  • Severe rhythm or conduction disorder (e.g., HR \< 50 or > 110 bpm, atrial flutter, prolonged QT >500 msec, second or third degree atrioventricular [AV]block if not treated with a pacemaker)
  • New York Heart Association Class III or IV congestive heart failure
  • Severe hepatic insufficiency (defined as alanine aminotransferase [ALT], aspartate aminotransferase [AST], or gamma-glutamyl transferase > 3 times the upper limit of normal [ULN], total bilirubin > 2 mg/dL, or Child-Pugh B or C) or active hepatitis in the investigator's opinion
  • A scheduled surgery that may be expected to lead to significant blood loss
