Brief Summary

To evaluate the safety profile of single intravenous (IV) dose levels of peginesatide in participants with chronic kidney disease(CKD) not on dialysis.

Detailed Description

This was a Phase 2a, randomized, double-blind, placebo-controlled, sequential dose escalation study conducted at a single clinical center. The study was designed to evaluate up to 6 treatment cohorts of 9 participants with CKD not on dialysis in the first cohort and 5 participants in each subsequent cohort. In each treatment cohort, participants were randomly assigned to receive either a single dose of peginesatide (n=7 in the first cohort, n=4 in subsequent cohorts) or placebo (n=2 in the first cohort, n=1 in subsequent cohorts). Participants were followed for a minimum of 28 days.

8. Weight ≥ 45 kg within 28 days prior to administration of study drug;

9. One white blood cell count ≥ 3.0 x 10^9/L within 28 days prior to administration of study drug; and

10. One platelet count ≥ 140 x 10^9/L and ≤ 500 x 10^9/L within 28 days prior to administration of study drug.

4. Hemoglobinopathy (e.g., homozygous sickle-cell disease, thalassemia of all types, etc.);

5. Hemolysis based on medical judgment;

6. Chronic, uncontrolled, or symptomatic inflammatory disease (e.g., rheumatoid arthritis, systemic lupus erythematosus, etc.);

7. C Reactive Protein (CRP) greater than 30 mg/L within 14 days prior to administration of study drug;
