Affymax, Inc. (Nasdaq:AFFY) and Takeda Global Research & Development Center, Inc., U.S., today announced that the U.S. Food and Drug Administration (FDA) accepted for review the New Drug Application (NDA) for peginesatide (formerly known as Hematide™) for the treatment of anemia associated with chronic kidney disease (CKD) in adult patients on dialysis.
“MEDCAC Meeting 3/24/2010 - Erythopoiesis Stimulating Agents (ESA) in Anemia Related to Kidney Disease.”
If approved, peginesatide will be the first once-monthly erythropoiesis stimulating agent (ESA) available for the treatment of anemia associated with CKD patients on dialysis in the United States.
Peginesatide is a synthetic, PEGylated peptidic compound that binds to and activates the erythropoietin receptor and thus acts as an ESA. The NDA included data from two Phase 3 studies (EMERALD 1 and 2) that evaluated the efficacy and safety of peginesatide, dosed once every four weeks, compared to epoetin alfa or epoetin beta, dosed more frequently (according to the product labels) in maintaining hemoglobin (Hb) levels. In the studies, over 1,600 CKD patients on dialysis who were receiving stable doses of epoetin were randomized to receive once-monthly peginesatide or continue treatment with epoetin. The EMERALD findings suggested that once-monthly peginesatide was comparable to epoetin in maintaining Hb levels in CKD patients on dialysis with anemia with a similar adverse event rate. The most common adverse events reported in the clinical studies were diarrhea, cough, dyspnea, nausea, and muscle spasm. A similar frequency of serious adverse events was reported between the EMERALD treatment groups.
