Eligibility Criteria
You may qualify if:
- ≥ 18 years old
- diagnosis of CRI and not receiving dialysis therapy (must be predialysis)
- measured or estimated (using the Cockcroft-Gault formula) creatinine clearance (CrCl) of ≤ 70 mL/min, or GFR ≤ 60 mL/min (using the MDRD formula):
- Cockcroft-Gault formula: CrCl = (140 minus age in years) x (body weight in kg) serum creatinine (mg/dL) x 72.0 For women, the value will be multiplied by 0.85
- MDRD formula: GFR = 170 x \[SCr\]-0.999 x \[Age\]-0.167 x \[0.762 if subject is female\] x \[1.180 if subject is black\] x \[sun\] -0.170SAlb\]-0.318
- mean Hgb \< 11 g/dL during the screening/baseline period (if subject is not already receiving rHuEPO therapy)
- for subjects currently receiving rHuEPO therapy, the subject must have: a stable rHuEPO dose for the past month; and a rHuEPO frequency of once weekly.
- white blood cell and platelet counts within normal limits
- serum vitamin B12 and folate levels above the lower limit of normal range
- transferrin saturation (TSAT) ≥ 20% during the screening period
- availability for follow-up assessments
- subject must be able to comprehend and be willing to, or have legally accepted representative, give written informed consent for participation in the study
You may not qualify if:
- scheduled to initiate dialysis
- uncontrolled hypertension (diastolic blood pressure \> 105 mm Hg or systolic blood pressure of \> 180 mm Hg during the screening/baseline period on two separate measurements)
- clinically unstable in the judgment of the investigator (eg, subject is in the intensive care unit, immediately post-myocardial infarction, etc)
- scheduled to receive a living donor kidney transplant
- treatment of grand mal epilepsy within the past 6 months
- moderate to severe congestive heart failure (NYHA class III or IV)
- clinical evidence of severe secondary hyperparathyroidism (parathyroid hormone level \> 1500 pg/mL)
- severe active chronic inflammatory process (eg, ulcerative colitis, peptic ulcer disease, rheumatoid arthritis, etc)
- currently receiving antibiotic therapy for systemic infection (enrollment may be postponed until the course of antibiotics has ended)
- known aspartate aminotransferase (AST) or alanine aminotransferase (ALT) greater than 3 times the upper limit of the normal range on more than one occasion within three months prior to screening
- known positive HIV antibody or hepatitis B surface antigen
- clinical evidence of current malignancy and/or receiving chemotherapy with the exception of basal cell or squamous cell carcinoma of the skin and cervical intraepithelial neoplasia
- active bleeding or RBC transfusion within eight weeks of enrollment
- androgen therapy within four weeks before enrollment
- known hematologic disease (eg, sickle cell anemia, myelodysplastic syndromes, hematologic malignancy, myeloma; hemolytic anemia, etc)
- +6 more criteria
