Safety and Pharmacokinetics of Single Intravenous Doses of Peginesatide in Healthy Volunteers

A Phase 1, Double-blind, Placebo-controlled, Dose Escalation Study of the Safety and Pharmacokinetics of Single Intravenous Doses of Peginesatide in Healthy Volunteers

The purpose of this study is to evaluate the safety, pharmacokinetics (PK), and minimum pharmacologically active dose of peginesatide in Healthy Volunteers.

This was a Phase 1, double-blind, placebo-controlled trial of peginesatide, an erythropoiesis stimulating agent, with approximately 7 treatment cohorts and 7 healthy volunteer participants per cohort. In each cohort of 7 participants, a ratio of 5:2 participants was randomly assigned to receive a single dose of peginesatide or placebo, respectively, administered as an intravenous infusion. Planned peginesatide dose levels were to escalate by cohort. The study was conducted at a single clinical center.

Main eligibility criteria:

• Participant is a healthy male, age ≥ 18 years and ≤ 40 years, with body mass index (BMI) ≥ 18 and ≤ 30 kilograms per squared meter (kg/m^2), and weight ≥ 50 and ≤ 95 kilograms (kg)
• Participant has hemoglobin of ≤ 16 grams per deciliter (g/dL) at the time of study entry
• Participant has normal iron stores
