Clinical Trial Summary

This study assessed the comparability of the pharmacokinetics (PK) of epoetin following intravenous administration of Hospira Epoetin and Epogen/Epoetin Alfa (Amgen) in patients with chronic renal failure receiving hemodialysis treatment.

Description:

This is a multicenter, active-controlled, cross-over, evaluator-blind, Phase I study in patients with chronic renal failure requiring hemodialysis. The study comprises a 4-week Screening Period, a 1-week Pre-Treatment Period, a 1-week Treatment Period 1, a 1-week Treatment Period 2 and a Follow-up visit at Week 7.

Subject eligibility will be determined during the 4-week Screening Period. All subjects must be optimally titrated and stable to qualify for entry into Pre-Treatment Period.

During the 1-week Pre-treatment period the patients will continue on the same stable dose as they received during the Screening Period. Blood samples will be collected during the Pre-Treatment Period to assess pharmacokinetics of Epogen. Eligible subjects will be randomized at Day 1 of Treatment Period 1 to receive either Epoetin Hospira or Epogen (Amgen) by intravenous (IV) bolus injections administered three times a week for 1 week.

Subjects will then be switched to receive the alternate study drug for three times a week for 1 week in Treatment Period 2. Blood samples will be collected during Treatment periods 1 and 2 to assess pharmacokinetics of Epoetin Hospira and Epogen.

Primary endpoint, i.e. pharmacokinetics concentrations, will be evaluator blinded. After completing Treatment Period 2, all subjects will receive standard of care treatment and will undergo a Follow-up Visit at Week 7 (i.e., 28 days after Treatment Period 2).

If hormonal contraceptives are used, the specific contraceptive must have been used for at least 3 months prior to randomization. If the subject is currently using a hormonal contraceptive, she should also use a barrier method during this study and for 1 month after last dose of Study Medication (Dosing Day 3 of Treatment Period 2).

Exclusion Criteria:

• A subject with any active, uncontrolled systemic disease that in the investigator's opinion may be significant to exclude participation in the study , including but not limited to microbial, viral or fungal infection or mental disease (including demyelinating diseases such as multiple sclerosis).

• History of drug abuse or alcohol abuse within 2 years prior to randomization as determined by the Investigator or a positive serum or saliva drug screen during the Screening Period or on Day 1 of each Treatment Period.

• Significant drug sensitivity or a significant allergic reaction to any drug, as well as known hypersensitivity or idiosyncratic reaction to epoetin (or it's excipients, including albumin) or any other related drugs.

• A subject who in the Investigator's opinion, has any clinically significant abnormal laboratory evaluations, including Human Immunodeficiency Virus (HIV), Hepatitis B virus surface antigen (HBsAg) and liver function taken at Screening Visit.

• Current treatment with long-acting epoetin analogues such as Aranesp.

• The following within 6 months prior to randomization: unstable congestive heart failure (New York Heart Association [NYHA] class III or IV), cerebrovascular accident, myocardial infarction, coronary angioplasty or by-pass surgery.

• Uncontrolled hypertension in Investigator's opinion within 4 weeks prior to randomization.

• A subject who has received a recent (within last 6 months) live or attenuated vaccination (except flu vaccination).

• A female subject who is pregnant, nursing, or planning a pregnancy during the study.

• Donated or lost >= 457 ml (i.e., 1 pint) blood volume (including plasmapheresis) or had a transfusion of any blood product within 3 months prior to randomization.

• Known clinically manifested untreated deficiency of folic acid and/or vitamin B12.

• Current participation or participation in a drug or other investigational research study within 30 days prior to randomization.

• May not be able to comply with the requirements of this clinical trial, communicate effectively with study personnel, or is considered by the Investigator, for any reason, to be an unsuitable candidate for the study.

• Known positive test for anti-epoetin antibodies.
