Participant gender:
All
Summary
The purpose of this study is to compare once a week and once every other week darbepoetin alfa on the change in hemoglobin levels between the screening/baseline period and the evaluation period (weeks 25-30). This study will also assess the change in mean hemoglobin over 4 week intervals, instability of hemoglobin concentrations, darbepoetin alfa dosing requirements and red blood cell transfusions.

Criteria
Inclusion Criteria: - -Receiving hemodialysis for at least 6 months before screening -
-Clinically stable as judged by the investigator - Stable IV rHuEPO therapy administered 1,
2 or 3 times per week for at least 8 weeks before screening (stable is defined as less than
or equal to 25% change [up or down] in weekly dose and no change in frequency over 8 weeks)
- Adequate iron stores (serum ferritin greater than or equal to 100μg/L) during the
screening period - Available for follow up assessments - Before any study specific
procedure is carried out, the subject, or his/her legally acceptable representative must
give informed consent for participation in the study Exclusion Criteria: - -Treatment for
grand mal epilepsy in the last 6 months - Congestive heart failure (New York Heart
Association [NYHA] class III or IV)- - Uncontrolled hypertension, defined as a predialysis
diastolic blood pressure measurement greater than or equal to 110mmHg during the screening
period - Clinical evidence of current uncontrolled hyperparathyroidism (e.g., serum
parathyroid hormone greater than 1500pg/mL) within the past 12 months - Major surgery
within 3 months before screening (excludes vascular access surgery) - Previously diagnosed
HIV or chronic hepatitis B infection - Clinical evidence of current malignancy excluding
basal cell or squamous cell carcinoma of the skin - Systemic hematological disease (e.g.,
sickle cell anemia, myelodysplastic syndromes, hematological malignancy); myeloma;
hemolytic anemia - Alanine transaminase (ALT) and aspartate transaminase (AST) greater than
2 times the upper limit of the normal range - RBC transfusion(s) within 12 weeks before
screening or during the screening/baseline period, or active bleeding - Clinical evidence
of current systemic infections - Androgen therapy within 12 weeks before screening - No
prior treatment with darbepoetin alfa - Currently enrolled in, or has not yet completed a
period of at least 30 days since ending, other investigational device or drug trial(s).
Subjects receiving other investigational agent(s) may only enter the study after discussion
and agreement with Amgen - Pregnancy (women of child-bearing potential must be using
adequate contraception) - Breast feeding - Psychiatric, addictive, or other disorder that
compromises ability to give truly informed consent or is likely to alter compliance -
