Results of the international study were presented at the American College of Cardiology's annual meeting in San Francisco on March 10 and published simultaneously online by The New England Journal of Medicine.
Initiated in 2006, the RED-HF (Reduction of Events With Darbepoetin Alfa in Heart Failure) trial involved 2,278 anemic heart failure patients at 453 sites in 33 countries.
Patients were randomly given either darbepoetin alfa or placebo. In the darbepoetin alfa group, 50.7 percent of the patients experienced death from any cause or hospitalization for worsening heart failure. In the placebo group, 49.5 percent of the patients experienced similar clinical outcomes.
The trial was funded by Amgen, the maker of darbepoetin alfa (trade name: Aranesp).
“This landmark study provides answers to caregivers who treat patients with heart failure complicated by anemia,” says James Young, M.D., cardiologist and Chair of the Cleveland Clinic Endocrinology & Metabolism Institute, and co-investigator of the RED-HF trial. “Our findings do not support the use of darbepoetin alfa to treat anemic heart failure patients.”
Anemia, the lack of red blood cells, is a common and serious problem in people who suffer from heart failure. It can lead to worse quality of life, higher rates of hospitalization and death. Treatment options have focused on correcting anemia with the use of intravenous iron or drugs that stimulate red blood cells.
“The benefits of erythropoietin-stimulating agents (ESAs) such as darbepoetin alfa to treat patients with heart failure and anemia have been questioned due to contradictory research findings,” says Karl Swedberg, M.D., Ph.D., a senior professor at the Sweden-based Department of Medicine, Sahlgrenska Academy, University of Gothenburg, and co-investigator of the RED-HF trial.
“Our study results show that the use of darbepoetin alfa to stimulate the production of red blood cells is an ineffective treatment for patients with heart failure and anemia.”
According to the study, researchers found that darbepoetin alfa treatment led to an early and sustained increase in hemoglobin compared with placebo. However, darbepoetin alfa treatment did not reduce the risk of death from any cause or hospitalization from heart failure.
Findings suggest that hemoglobin is a marker of poor prognosis in heart failure, rather than a therapeutic target. There were no new safety findings identified in the study. However, researchers observed an increased risk of thrombosis in the darbepoetin alfa group.
Researchers note that further research is needed to identify treatment options for this patient population.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
