An Exploratory Sub-study for the RED-HF™ (Reduction of Events With Darbepoetin Alfa in Heart Failure) Trial

April 7, 2011 updated by: Amgen

Double-Blind, Placebo Controlled, Multicenter Study to Assess the Effect of Darbepoetin Alfa Treatment on Cardiac Function and Disease Specific Biomarkers in Subjects With Symptomatic Left Ventricular Systolic Dysfunction and Anemia: An Exploratory Sub-study for the RED-HF™ Trial

The purpose of Study 20060172 was to measure echocardiographic parameters and biomarkers in a subgroup of study subjects enrolled in Study 20050222 (the RED-HF Trial). This substudy 20060172 was terminated early due to feasibility constraints. All subjects enrolled in 20060172 were also enrolled in Study 20050222, which is ongoing. Study data will be analyzed when Study 20050222 ends, since unblinding before then would adversely affect Study 20050222.

Intervention / Treatment
Placebo Comparator: Placebo
Drug: Placebo
Placebo group to receive volume and dose frequency changes resembling titration dosing in the treatment group.
Experimental: Active
Drug: Darbepoetin alfa

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Time Frame

Time Frame: 12 months
12 months

Secondary Outcome Measures

Outcome Measure
Time Frame
Explore correlations among measures of cardiac systolic and diastolic function, surrogate markers of cardiac injury and function, and clinical outcomes in heart failure subjects treated with darbepoetin alfa or placebo.
Time Frame: 12 months
12 months
Investigate the effect of treatment of anemia with darbepoetin alfa on novel biomarkers relevant to the pathophysiology and progression of heart failure
Time Frame: 12 months
