Clinical Trial: Safety of Single Doses of Hematide in Patients with Chronic Kidney Disease

This study is currently recruiting patients.

Sponsored by: Affymax
Information provided by: Affymax


The purpose of this study is to evaluate the safety, pharmacodynamics (PD), and pharmacokinetics (PK) of single intravenous dose levels of Hematide in patients with chronic kidney disease (CKD) who are not on dialysis.

Condition Treatment or Intervention Phase

 Drug: Hematide
Phase II

MedlinePlus related topics:  Kidney Diseases

Study Type: Interventional
Study Design: Treatment, Randomized, Double-Blind, Placebo Control, Parallel Assignment, Safety Study

Official Title: A Phase 2a, Randomized, Double-blind, Placebo-controlled, Sequential Dose Escalation Study of the Safety, Pharmacodynamics, and Pharmacokinetics of Single Intravenous Doses of Hematide™ in Patients with Chronic Kidney Disease Who are not on Dialysis and Who Have Not Had Prior Erythropoiesis Stimulating Agent (ESA) Treatment

Further Study Details: 
Primary Outcomes: Evaluate the safety profile of single intravenous (IV) dose levels of Hematide in CKD pre-dialysis patients
Secondary Outcomes: Evaluate the dose response relationships of a single dose of Hematide on hemoglobin, reticulocytes, and iron stores; Evaluate the PK profiles of single dose levels of Hematide administered intravenously in pre-dialysis patients; Determine the pharmacologically active dose of Hematide administered intravenously in pre-dialysis patients
Expected Total Enrollment:  54

Study start: March 2005;  Expected completion: December 2005
Last follow-up: October 2005;  Data entry closure: November 2005

Up to a maximum of 54 pre-dialysis patients, aged 18-75 years, with hemoglobin ≥ 9 g/dL and ≤ 11 g/dL secondary to chronic kidney disease who have not had previous treatment with ESAs and who meet eligibility criteria will be enrolled in up to 6 dose cohorts (9 patients per cohort, 7 on study drug and 2 on placebo). Patients will be followed through Day 29 or until stabilization of adverse events.
