A Randomized, Double-blind, Placebo-controlled, Study to Assess Changes in Physical Function in Elderly Patients With Idiopathic Anemia of Aging (IAA) Receiving Epoetin Alfa (PROCRIT�)

.Some elderly patients have anemia (reduction in hemoglobin level, or low red cell count) without obvious cause. Anemia occurs commonly with aging and is a frequent medical condition in individuals over the age of 65. Physical performance and function is worse in individuals who are anemic. This is a randomized, double-blind, placebo-controlled, multi-center study to assess physical function (to include falls) and fatigue in approximately 80 elderly patients with chronic anemia (anemia present for at least 3 months) and who are receiving weekly Epoetin alfa. The study will also evaluate hemoglobin levels (oxygen carrying protein in red blood cells), safety, fatigue and cognitive function. The study hypothesis is to demonstrate the study drug will be more effective in treatment of chronic anemia than placebo, resulting in the improvement of physical function and subsequent disabilities, with minimal adverse events and the study drug is generally well-tolerated. The patients will receive weekly injections of Epoetin alfa (PROCRIT®) or placebo at a starting dose of 10,000 units administered subcutaneously (under the skin).
