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.

Further study details as provided by Amgen:

Primary Outcome Measures:
  • To determine whether treatment of anemia with darbepoetin alfa, in patients with heart failure and anemia, results in changes in cardiac structure and function. [ Time Frame: 12 months ]

Secondary Outcome Measures:
  • 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 ]
  • 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 ]

Enrollment: 12
Study Start Date: January 2007
Study Completion Date: October 2007
Primary Completion Date: October 2007 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Active Drug: Darbepoetin alfa
Starting dose: 0.75 mcg/kg subcutaneously Q2W. Subsequent doses: Darbepoetin alfa group to receive darbepoetin alfa titrated to achieve Hb target of 13.0 g/dL, not to exceed 14.5 g/dL.
Placebo Comparator: Placebo Drug: Placebo
Placebo group to receive volume and dose frequency changes resembling titration dosing in the treatment group.

Inclusion Criteria:

  • Signed informed consent for Study 20060172
  • Randomized into Study 20050222

Exclusion Criteria:

  • Any condition or situation that, in the investigator's opinion, may put the subject at significant risk, render the subject unsuitable for accurate echocardiography, may confound the study results, or may interfere significantly with the subject's participation in Study 20060172 or in Study 20050222.
