Extension Study to Evaluate Safety and Tolerability of Peginesatide for Long-Term Treatment of Anemia in Participants With CKD
Condition: Chronic Renal Failure; Chronic Kidney Disease; Anemia
MeSH terms: Kidney Diseases; Renal Insufficiency, Chronic; Renal Insufficiency; Kidney Failure, Chronic; Anemia
Intervention: peginesatide
Intervention description: Participants received the same initial peginesatide dose as was administered at the end of the previous peginesatide treatment study (NCT00228449) in which the participant was enrolled. The median first dose at study start was 0.087 milligram per kilogram (mg/kg) with an interquartile range of 0.064 to 0.123 mg/kg. Each participant was to receive peginesatide as an injection administered intravenously once every 4 weeks for approximately 54 months in this trial.

Summary:

      The purpose of this study was to evaluate the long term safety and tolerability of
      peginesatide for the maintenance of hemoglobin in participants with chronic kidney disease
      (CKD) who had received at least 24 weeks of peginesatide treatment in an earlier study.
    

Eligibility criteria:

        Inclusion Criteria:

          -  Participant is informed of the investigational nature of this study and has given
             written, witnessed informed consent in accordance with institutional, local, and
             national guidelines

          -  Males or females ≥ 18 years of age. Pre-menopausal females (with the exception of
             those who are surgically sterile) must have a negative pregnancy test at screening;
             those who are sexually active must practice a highly effective method of birth control
             for at least 4 weeks prior to study drug administration, and must be willing to
             continue contraception until at least 4 weeks after the last dose of study drug.

          -  Participant who has received at least 24 weeks of peginesatide dosing in a previous
             Affymax-sponsored study

          -  One hemoglobin value of > 10.0 g/dL in the 4 weeks prior to study drug administration

        Exclusion Criteria:

          -  Known intolerance to peginesatide or pegylated products

          -  History of antibodies to any erythropoiesis stimulating agent (ESA) or history of pure
             red cell aplasia (PRCA)

          -  High likelihood of early withdrawal or interruption of the study (e.g., participant
             suffers from any clinically significant medical disease or condition that may, in the
             Investigator's opinion, interfere with safety, assessment, or follow-up of the
             participant)

          -  Anticipated life expectancy < 18 months

          -  Receipt of any ESA other than peginesatide at any time after participant enrollment in
             the previous Affymax-sponsored study
